The program scope is defined by an analytical study done by the Program Engineer for each feeder and by the Distribution Feeder Management Plan which was created and is updated by consulting The Distribution Engineering Standards Engineer and Asset Management Manager. . Reliability, avoided costs, and capital offset of future O&M expense data is collected and analyzed by Asset Management. This information is normalized and entered into a selection toolwhich then ranks the feeders. o The regional distribution engineers for the East, South, North, West and Spokane regions are consulted regarding the feeder ranking and feeder p rioritization with i n thei r respective reg ions, o The program manager then balances the prioritized feeders between the states, rural/urban split, and regions. . The program manager then collaborates with Electric Operations and Contractors to coordinate the work and track the budget, scope, and schedule. 2 BUSINESS PROBLEM The Distribution Grid Modernization Program provides value to customers and shareholders through the following objectives of improving: o Grid Reliability - Replacing aging and failed infrastructure that has a high likelihood of creating customer outages and a need of an unplanned crew call-out which costs more than planned work and would filter into higher rates for customers. o Without programs like Grid Modernization and Wood Pole Management there would be an average 40 pole failure events per year effecting an average of 80 customers for 4.8 hours per event. Totaling a customer impact value of approximately $24,000 per event totaling to $960,000 per year. Exhibit No. 8 Case No. AVU-E-19-04 H. Rosentrater, Avista Schedule 3, Page 3 of 186 o Page 1 of8 Driver o Energy Efficiency - Replace equipment such as old conductor and transformers that have high energy losses with new equipment that is more energy efficient and improve the overall feeder energy performance. This creates the need for less power generation or acquisition and equates to lower rates for customers. Operational Abilitv - Replace conductor and equipment that hinders outage detection and installautomation devices that enable isolation of outages. o This means shorter outrages for customers because the areas that failed can be identified faster and possibly reroute power automatically. Currently the Grid Modernization Program in the only company initiative installing these devices. o The installation of automated line devices on a feeder of 1600 customers reduces an average outage duration from 3 hours to 5 minutes per event for 1200 of those customers. Safety - Focus on public and employee safety through smart design and work practices. o Replacing aging and failed infrastructure that puts employees and customers at risk of property damage and injury. o Bringing infrastructure up to current National Electric Safety Code. o Eliminate PCB risk to the public by eliminating transformers containing known PCB's. o The Grid Modernization program lowers the risk of high severity safety (S4) events, defined below, as follows: . 54 events are categorized as having potential for multiple serious injuries or loss of an individual life; major damage to propefty or business, and a public health infrastructure impact up to 72 hours. . Base Case (do nothing) has the risk of 10 54 events every 50 years with a total cost of $52.3M. . The Grid Modernization Program brings this risk down to 2 events in 50 years with a total cost of $10.4M. Another Safety objective of The Distribution Grid Modernization Program is to address Washington State's Department of Transportation (WSDOT) Target Zero requirements, which states that utilities move all non- breakaway structures, such as power poles and pad mount transformers, out of highway clear zone as defined in the 1U2A05 AASHTO "A Guide for Accommodating Utilities Within Highway Right-of-Way," which is attached for reference. Washington State law requires that we complete this task by year 2030. Currently this is the only program within Avista actively addressing this mandate.

Rosentrater, Avista Schedule 3, Page 5 of I 86 Distri b uti on G rid Modernization o ln order to address Avista's entire system and every customer in a 60 year cycle, the program would need to address an average of 190 miles per year of Avista's 11,300 total overhead and underground circuit miles. The miles of work planned is ultimately driven by the approved budget and generally can only be projected for 5 years. At the current funding level and average cost per circuit mile, represented in Table 2 below, it will take us approximately 90 years to address the entire system and every customer.

The red line represents the reduction of outages of these sub-reasons on the feeders that the Grid Modernization program has completed to date. You will see the Grid Modernization addressed feeder outages are trending down whereas the system wide outages are trending up. lf 2015, which is when Avista experienced a large wind storm, was excluded the system wide outages would be trending slightly downward but the Grid Modernization addressed feeders are trending downward at a faster rate.

This costs more for set up and traveltime, flagging, etc. which means higher rates for customers. This also means the customer could have multiple different planned outages and have multiple different street closers while the crews did specific work at multiple different times. The risk reduction is also cut in half compared to the comprehensive work completed by the Grid Modernization program. Per year MM YYYY MM YYYY The Grid Modernization Program combines the recommendations from two Avista system performance studies into its work activities to provide refreshed system feeders with new automation capabilities across Avista's distribution system. The first of these studies was performed in 2009 and had a system efficiencies team evaluate the potential energy savings for distribution system upgrades and analyzed the value of selective rebuild with "right sized" conductor replacements for reducing energy losses, improve reliability, and meeting future load grov'rth demand. A second study was conducted in 2013 to assess the benefits of distribution feeder automation for increased reliability, operability, and load Ioss savings. The reliability, energy losses, reductions in operations and maintenance (O&M) costs and capital investment from the individual efficiency programs under consideration were combined on a per feeder basis. This approach provided a means to rank and compare optimalfeeder modernizing and net resource costs to achieve the desired benefits. The system efficiencies team evaluated several efficiency programs to improve both urban and rural distribution feeders. The programs consisted of the following system enhancements:o Conductor losses; Exhibit No. 8 Case No. AVU-E-19-04 H. Rosentrater, Avista Schedule 3, Page 8 of I 86 o o Page 6 of 8 O Distrib ution G rid Modern ization o o o Distribution transformer losses and PCB mitigation;. Secondary district losses;o Conservation Voltage Reduction (CVR);. lntegrated VolWar Control (lWC), and;o Fault Detection lsolation and Restoration (FDIR) opportunities; The Grid Modernization Program's charter criterion has grown to include a more holistic approach to the way Avista addresses each project. This vital program integrates work performed under various operational initiatives at Avista including the Wood Pole Management Program, the Transformer Change-out Program, the Vegetation Management Program, various budgeted maintenance programs and the Feeder Upgrade Program. The ancillary work of the Grid Modernization Program includes the replacement of undersized and deteriorating conductors, replacement of failed and end-of-life infrastructure materials including wood poles, cross arms, fuses and insulators. lnaccessible pole re-alignment, right-away, undergrounding, joint use coordination and clear zone compliance issues are addressed for each feeder section. This systematic overview enables Avista to cost-effectively deliver a modernized and robust electric distribution system that is more efficient, easier to maintain and more reliable for our customers. The long-term plan aims to upgrade 190 circuit miles per year to cover the whole distribution system in a 60 year cycle. According to Avista's Asset Management subject matter experts a 60 year cycle is optimal due to the average mean time to failure and age profiles of our systems assets. lt also coordinates well with the Wood Pole Management's (WPM) program 20 year cycle. The average cost for the Grid Modernization program to rebuild a circuit mile is $110,000. !n orderto meet the 60 year cycle $21M would be needed each year. Alternatively we could complete the entire system in 80 years for $15.5M each year, but that means we would not address the entire system until approximately the year 2093. This would not be prudent at Asset Management shows a bow wave of infrastructure reaching end of life by the year 2060. Currently the program is still ramping up to its fully desired resource needs and therefore has only requested $17.5M for 2017. The plan is to have enough resources, design, and funding in place to be able to construct the 190 circuit mile per year goal by 2019. The Grid Modernization Program consists of the following fully allocated resources: Project Manager, Associate Project Manager, Distribution Engineer, six internal designers (customer project coordinators/CPC), and five contract designers and has the following part time shared resources: analyst, and two in- house and two contract field inspector/auditors, Construction labor usually consists of a mix of in-house and contract line crews totaling around eight to twelve five man crews. The program also interfaces with and relies on assistance from the following departments which might require additional resources; Real Exhibit No. 8 Case No. AVU-E-19-04 H.

Often, the work addresses failed asset replacements or customer requests that are unplanned. Occasionally, larger proiects with an identified need and short timeframe for implementation are constructed under the Distribution Minor Rebuild business. Minor Rebuild work occurs regularly and historical averages are used to estimate the appropriate funding allocations. The loca! area operation engineers, general foremen, and area construction managers manage the work as it is identified throughout the given construction season. A more formal governance is currently being developed for this business case, which will provide a check or gate on which projects in the business become approved for scheduling. 2 BUSINESS PROBLEM The work done under the distribution minor rebuild is driven by keeping the distribution system in reliable condition for customers and safe condition for the workers, responsiveness to unplanned damaged to distribution assets not related to weather events, as well as small customer driven rebuilds. Throughout the entire distribution system, minor rebuilds or replacements of asset units need to be completed to maintain system reliability and safety. Below is a categorical breakdown which fall within the Distribution Minor Rebuild business. Customer Reouested Rebuilds - Work is initiated by an existing customer or property owner, and the costs associated with the work are typically reimbursed by the requesting party. Trouble Related Work - Work required to repair damaged facilities related to non- storm related outages. A common example of trouble related work is a car hit pole. Joint Use Requested Rebuilds - "Make-ready" work required to existing facilities in order to accommodate joint use installations. The costs associated with the joint use work are typically reimbursed by the requesting joint use party(s). Hxhlblt No. 6 Case No. AVU-E-19-04 H.

General Rebuilds - Work can be initiated through a variation of sources. General rebuild work is typically small in scope (i.e. one ortwo poles) and typically addresses unplanned work that is identified as priority because of: o NESC code violations (e.9., inadequate clearance) o Failed or failing equipment (e.9., rotten cross-arms) o lnadequately sized or classed equipment for serving an existing customer or group of customers (such as an undersized transformer or fuses) o Other minor projects include minor loop feeds, installing air switches, line regulators, line reclosers, and short reconductoring projects for reliability improvements. Figure I shows a pie chart of the mentioned categorical breakdown to demonstrate the magnitude of each category. The figure gives a three year average, which has remained historically constant.

Rosentrater, Avista Schedule 3, Page l2 of 186 o Distribution Minor Rebuild ln 2016, 1,115 work orders were created with the average cost equaling only $4,400, which demonstrates the business is made of thousands of small dollar amount jobs. Occasionally larger rebuild projects, such as small reconductor project, are undertaken as Distribution Minor Blanket projects. A common reason is the work is considered critical and non-discretionary. Only 28 work orders were created over $25,000, averaging $54,000 per work order in 2016. Figure 2 displays a breakdown of the different types of charges that occur in the Minor Rebuild. The majority of charges are from specific work orders. Distribution Minor Rebuild work often consists of isolated, replacement of failed asset(s) that do not lend themselves to a specific project (i.e. trouble related work), which are charges falling under craft and non-craft expenditures. ?:OLG Types of Charges to Minor Rebuild r Craft Related Project Expenditures r Non-€raft Related Project Expenditures a Specific Work Order Charges Figure 2: Typu of Chorges lo Minor Rehuild (2016) The following is a brief description of each type of charge. .

By not funding the business will also affect the ability to respond to customers' needs for modifications to their electrical service. Lastly, it is acknowledged some minor rebuilds left unrepaired will not result in immediate catastrophic failures to the distribution system (i.e. a broken pole pin insulator), but over time an adverse accumulation of unrepaired assets would greatly put line workers and the general public at risk as minor asset failures begin to deteriorate pockets of the distribution system. o 3 PROPOSAL AND RECOMMENDED SOLUTION Figure 3 is the historical spend required to fully fund the Minor Rebuild business.

Customer Requested Rebuilds are typically a credit to the business because most are reimbursed in part or in full by the customer. As shown in 2014, Customer Requested Rebuilds are not always reimbursed back to the business. The Distribution Minor Rebuild business reaches across multiple departments in Engineering and Operations. The business involves operation area engineers, local customer project coordinators, and construction technicians who work directly with customers and perform all the designs for the business. Once the minor projects are designed and ready for construction, field personnel such as a Foremen, Journeyman Linemen, Line Servicemen, Meter men, Equipment Operators execute the work. The Distribution Minor Rebuild business provides a solution for the utility to address small unplanned asset failures and customer driven modifications to the distribution system, but excludes fixes to the system considered to be maintenance. While the work is unplanned, minor rebuilds to the distribution system occur on a regular basis every year and make up a significant portion of the business within Engineering and Operations. While unplanned and isolated minor rebuilds will always exists in the distribution system, unplanned work is minimized to the greatest extent through other systematic infrastructure programs.

This analysis is used to direct the Wood Pole Managementwork that includes inspecting and maintaining Avista's poles, hardware and equipment on a twenty year cycle. The operating guidelines are documented in the Distribution Feeder Management Plan (DFMP). The analysis is documented in the Electric Distribution System 2016 Asset Management Plan. Asset Maintenance then collaborates with Electric Operations and contractors to coordinate the work. Asset Maintenance tracks the work budget, scope, and schedule. 2 BUSINESS PROBLEM The major drivers for the program are system reliability, improved cost performance, and reduced customer outages. These drivers are obtained by replacing defective poles, associated hardware, and equipment at its end of life. The National Electric Safety Code (NESC) is adopted as Washington State Law under WAC 296-45-045. More specifically Part 013 describes the application, Part 121 describes the inspection interval, and Part 212A describes documentation and correction of the pole inspection results. The currentWood Pole Management (WPM) program inspects and maintains the existing distribution wood poles on a twenty year cycle and the transmission poles on a fifteen year cycfe. Avista has 7,7O2 overhead distribution circuit miles. The average age of a wood pole is twenty-eight years with a standard deviation of twenty-one years. Nearly 20o/o of all poles are over fifty years old and we have an estimated 240,000 Distribution poles in the system. This means approximately 48,000 poles are currently overfifty years old. Our current inspection cycle allows us to reach approximately 12,000 poles each year. Along with inspecting the poles, we inspect distribution transformers, cutouts, insulators, wildlife guards, lightning arresters, crossarms, pole guying, and pole grounds. The average asset life of this equipment is fifty-five years and requires replacement along Exhibit No. 8 Case No. AVU-E-19-04 H. Rosentrater, Avista Schedule 3, Page 17 of 186 o Business Case Justification Narrative Page 1 of 8 Mark Gabert Wood Pole Management with the pole work. The inspections document asset condition and indicate what work is required to replace assets that are damaged or near failure point. The asset condition is observed and documented during the pole inspection process as indicated in both the S- 622 Specification for the lnspection of Poles, and the Distribution Feeder Management Plan (DFMP). Designs and work plans are then created to replace the aging infrastructure. The construction work to replace the assets is part of this program. The work is required now to keep pace with the aging assets and expected failure rate. Figure 1 below shows the increased rate at which the poles are reaching the seventy-five year end of life. lf this work is not maintained the aging infrastructure will cause an increasing rate of failures leading to increased outages and higher construction costs. ln addition to the risks of outages and failures with the aging equipment, the additional risks associated with this program pertain to the following: Environmental: Risks include; large volume transformer oil spill, dfficult hazardous waste cleanup, moderate to low volume or level of PCBs, minimal impact to waterways, repeated or moderate air emission exceedance. lf the program is unfunded the potential occurrence is greater than 4 spills per year. lf funded, the potential occurrence is less than 1 per 50 years.

This reduction in outage events results in significant customer benefit. This reduction also demonstrates increased reliability and safety along with a reduction in outages.

Note there are significant improvements to some events such as; annual squirrel events being reduced from nearly 750 to around 240 events. This improvement has been realized by adding wildlife guards to the top of transformers in order to prevent squirrels from touching exposed power connections which can result in outages. Both the transformer and cutout\fuse events have been reduced by over 50% through the replacement of aged equipment. Table 2 also reveals a concerning upward trend of Pole-rotten events that indicate the impact of the aging poles. Note that the calculated cost to customers for a pole failure is $24,400 based on an average duration of 4.8 hours for 80 customers, per Asset Management, Other key OMT events that have been significantly reduced from 2009 to 2016 include Transformer, CutouUFuse, and Squirrel. The combined cost impact to customers in 2015 alone for those events was $2,265,600. See Figure 2. O Exhibit No. 8 CaseNo. AVU-E-19-04 H.

Asset Management and Distribution Engineering will contanue to monitor system reliability to determine if adjustments are required in the future. Distribution Wood Pole Management is an ongoing cyclical program that proactively replaces aging assets. By replacing assets before they fail, outage risks are reduced and replacement costs are reduced through planned work. lnvesting in the infrastructure increases life-cycle performance, safely, reliably, and is cost effective through the use of unit based pricing. Figure 2 below shows the significant improvement in "events per mile of feeder" resulting from this Program.

The work is mostly unplanned and non-specific in nature, but occurs regularly and historical averages are used to estimate a quantity. The loca! area operation engineers and area construction managers manage the work as it is identified throughout the given construction season. 2 BUSINESS PROBLEM The Electric Distribution and Transmission Road Moves/Relocation program is driven by compliance mandated by "Franchise Agreement" contracts with local city and state entities and "permits" issued by Railroad owners. ln general, a "Franchise Agreement" generally refers to a non-exclusive right and authority to construct, maintain, and operate a utility's facility using the public streets, dedications, public utility easements, or other public ways in the Franchise Area pursuant to a contractual agreement executed by the City and the Franchisee. Although each Franchise Agreement or permit is a little different, they all serve a similar purpose in providing for utility access along city, county, state and railroad right-of-way (ROW). The agreement(s) make provisions forAvista to installelectric equipment along these ROW's in order to provide service to Avista customers. Within each agreement are provisions for relocation of utilities at the request of the ROW owner. These request are usually driven by road and or sidewalk re-design projects. For reference, franchise 95-0990 recorded with Spokane County paragraph Vl states "lf at any time, the County shall cause or require the improvement of any County road, highway or right-of-way wherein Grant* maintains facilities subject to this franchise by grading or regarding, planking or paving the same, changing the grade, altering, changing, repairing or relocating the sarrre or by constructing drainage or sanitary sewer facilities, the grantee upon written notice from the county engineer shall, with all convenientspeed, change the location or readjustthe elevation of its system or other facilities so that the same shall not interfere with such County work and so that such lines and facilities shall conform to such new Business Case Justification Narrative Bxhibit No. 8 case No. AVU-E- l9-04 Page 1 0f 4 H. Rosentrater, Avista Schedule 3, Page 25 of 186 a Cody Krogh Electric Relocation and Replacement Program grades or routes as may be esfablshed," For example, a State Department of Transportation (DOT) is widening an intersection or highway, which requires Avista to relocate their overhead or underground electric facility to accommodate the new DOT design. A smaller example for instance is a local municipality is installing new ADA ramps on the corners of localstreet intersections, which sometimes requires Avista to relocate a utility pole to accommodate the new ramp design. The Electric Relocations are agreed to and executed per the jurisdictional Franchise Agreement or Permit. Work under Franchise Agreements or Permits are contractual, agreed upon, and if the terms of the agreement or permit are not executed a breach of contract will likely ensue. Also, state and local government departments which oversee highways, roads, and city streets incorporate the guidelines set forth in the American Association of State Highway Transportation Officials (AASHTO) Roadside Design Guide into the design of the highways and roads. The guidelines are based on the type of roadway and posted speed, but generally do not allow for any fixed objects inside the traveled way or sides of the roadway ("clear zones") for public safety. As a result, nearly all new road projects require utilities to relocate or remove all poles inside and outside the traveled way. The new roadside design guidelines allow for placement of new facility in a location that improves the safety of the driving public, thus reduces risk to Avista. Avista designers coordinate with each state or local road project to ensure the new relocations meet the clear zone standards, yet minimize cost. Most Franchise Agreements have provisions to prohibit the ROW owner from requiring the utility to move the same facility more than once over a span of years, usually five. The asset conditions replaced through Electric Relocations can vary since the relocations are unplanned and therefore not coordinated with Avista's Asset Maintenance programs. Most assets in an Electric Relocation project are replaced because they are unsalvageable and close to their useful life. ln the case of relocating newer assets, efforts are made to re-use as much material as possible. Under a Franchise Agreement or Permit, Avista is allowed to occupy space within a ROW owned by the respective jurisdiction in order to serve its customers. Electric relocations occur every year during the construction season, but are unplanned, so historical trends are used to estimate the annual cost to fully fund all the relocation projects. The annual costs of electric relocations has very little variance year to year, therefore fully funding the business will likely ensure all electric relocations under Franchise Agreements or Permits will be completed. H. Rosentrater, Avista Schedule 3, Page 26 of 186 o o a Electric Relocation and Replacement Programo o 3 PROPOSAL AND RECOMMENDED SOLUTION Electric Relocation projects are managed, coordinated, and executed within the Operations department. When a transportation agency has a road project requiring Avista to relocate its facility, a Customer Project Coordinator (CPC) is designated full time to coordinate the project with the agency as the direct contact from Avista. The CPC manages, coordinates, and designs the relocation of Avista's distribution or transmission facility. He or she will meet with line foreman in the field to scope out the project and identify any construction obstructions (i.e. equipment access). The Real Estate group, under Environmenta! Affairs, often is involved in Electric Relocation projects to obtain further easements or get permits approved. Because the Electric Relocations business is unplanned work, contractually obligated, and adds high risk to the company if not completed, no alternative analysis is considered. This program is demand driven and unplanned work. Funding allocation is based on historicalspending trends. The graph below shows the historicalspend for Electric Relocation eAfi -2016). The average spend over the six years is $2.3 million. However, at 2014 spend is thrown out as an outlier, it is clear the trend in electric relocations is trending upward. Because electric relocations are directly correlated with the number of highway and street projects, the reason for the upward trend in spend is likely an increase in transportation project spending.

They guide the program on any processes requiring modification or developing new processes to help improve the program. lnternal stakeholders include Construction Services, Distribution Engineering, Warehouse and Investment Recovery, Supply Chain, External Communications, Mobile Dispatch, Enterprise Asset lt/anagement, Customer Enterprise Technology, and Regional Business [Vlanagers. External stakeholders are state and local governments who have jurisdiction over roads and streets where Avista provides illumination. Neighborhood councils are a particular external stakeholder which is often involved before their neighborhood is converted to LED because the residential areas are sensitive to street lighting. 2 BUSINESS PROBLEM Any local or state government which has jurisdiction over streets and highways has an obligation to the general public they serve to provide acceptable illumination levels on their streets, sidewalks, and/or highways intended for vehicle driver and pedestrian safety. Avista manages streetlights for many local and state government entities to provide such street, sidewalk, and/or highway illumination for their streets by installing overhead streetlights. The primary driver for converting overhead streetlights from High-Pressure Sodium (HPS) lights to LED lights is the significant improvement in energy savings, lighting quality to customers, and resource cost savings. Secondly, converting streetlights to LED technology helps bring Avista in compliance with the Washington State lnitiative 937 (or the Clean Energy lnitiative), which ensured that at least fifteen percent of the electricity Washington state gets from major utilities comes from clean, renewable sources, and that Washington utilities undertake all cost-effective energy conservation measures. LED streetlight technology is part of the mentioned energy conservation measure. The desire to begin the LED Change-Out Program in2015 stems from an immediate savings in energy, positive financial impacts, benefits associated with personal injury and property theft, and resource cost savings.o Business Case Justification Narrative Page 1 of7Exhibit No. 8 CaseNo. AVU-E-19-04 H. Rosentrater, Avista Schedule 3, Page 29 of 1 86 . Each 100 watt and 200 watt HPS light replaced will save approximately 65 watts and 128 watts, respectively, per fixture. Once all of the 100 watt and 200 watt HPS street lights are replaced, the annual energy savings will be 9,903 MWH each year. . With respect to the financial impacts of converting to LED streetlight technology, the customer internal rate of return is 8.46%, assuming the current cost of materials and life expectancy of the photocells and LED streetlight fixtures. . From a public safety perspective, the consequence of converting to LED streetlights in lieu of replacing burned-out HPS bulbs shows a risk reduction for customers of nearly eight times less for potential injury, a serious fatal accident, and property theft. . Lastly, company resource demands are reduced after the initial conversion to LED technology. The Average Annual Labor Man-Hours for current practices of changing burned-out HPS bulbs is estimated at 5,200 man-hours and 2,600 equipment hours, while the average man-hours required during the fifteen year life of the LED fixtures are 3,200 man-hours and 1,800 equipment hours. ln 2011, the average cost to maintain a HPS streetlight was nearly $92 per fixture with only about $10 of the cost being the actual material. The remaining costs were the main constituents of the overall cost as seen in Figure 1. Material, Sro Equipment, Figure l: 2Al I Cost Breakdown of a HPS Lighl Fixture Also, a lifetime material usage analysis on the HPS light fixtures estimated a Mean Time to Failure (MTTF) for the various light fixture components.

Most LED fixtures have the capabilityto have real- time energy consumption measurements taken and reported back to Avista. Also, once all the streetlights are converted to LED, the number of service requests for streetlight burn-out should drop significantly from the number of service requests prior to 2015. 3 PROPOSAL AND RECOMMENDED SOLUTION Option Capital Cost Start Gomplete Do nothing $0 N/A Base Case (current practice of replacing burned-out HPS bulbs or replacing a fixture if broken) $1.70M Ongoing Optimized HPS Case (planned replacement of HPS bulbs and photocells) $1.67M 14t2015 12t2019 LED Case (change-out all fixtures to LED)$2.32M 10t2015 12t2019 Three alternative cases were considered in an analysis performed by the Asset Management Department of converting streetlights to LED technology. The current case or Base Case replaces failed HPS streetlight components only when they fail. The second case, called the LED Case, replaces the current HPS streetlights with new LED fixtures and implements a planned replacement at fifteen years for the light fixture and photocell. The analysis noted that inside the new LED Case model, a fifteen year replacement strategy proved more cost effective overthe lifecycle than running LED lights to failure. Thirdly, the Optimized HPS Gase represents keeping the current HPS light fixtures and performing planned replacements of the HPS bulbs and photocells at five year cycles for the bulbs and ten year cycle for the photocells.

The Base Case and the Optimized HPS Case, because they propose using HPS fixtures, have the same failure characteristics shown in Table 2. Table I, HPS Light Componenl Foilure Characteristics 3.4 5.7 7.4 4.4 7.3 10.5 6.7 10.6 16.3 o o Table 3 shows the failure characteristics assumed for LED fixtures and components based on manufacturer's information and an assumed failure shape characteristic.

While the Optimized HPS Case provides a better financial return to our customers compared to both the Base Case and LED Case when considering strictly labor and material costs, the energy savings associated with the LED Case becomes an overcoming driver. The customers will still see savings over the life of the LED fixtures compared to today's practices in the Base Case and eliminate the need for 2.3 Megawatts of generation at night. ln addition, customers will realize an annual system energy savings of 9,903 Megawatt hours.

The O&tvl cost in the Optimized HPS Gase would be higher than the Base Case since it includes a programmatic change-out of all HPS bulbs. The LED Change-Out Program achieves the objective of saving energy, reducing resource costs, and improving nighttime light quality, which are all objectives customers will immediately benefit from. The LED Change-Out Program has a five year timetable, beginning in 2015, to change-out all existing Avista owned non decorative streetlights to LED (Light Emitting Diode), which equates to over 35,000 change-outs. The program schedule is orientated by circuit feeder, similar to other programs. The priorities of what circuit feeders or cities in the service territory are to be completed first is based on efficiencies. At times, coordination with cities may impact the schedule of when an area is changed out. As shown in Table 4, the requested annual amount of nearly $2.32 million for five years (2015 -2019) is the minimum funding amount to complete the LED Change- Out Program in the five years. lf funded below the $2.32 million for five years, the realized O&t\4 savings to customers would be delayed to subsequent years, and to a lesser amount. However, if the Program is funded above the requested annual amount of $2.32 million for five years, customers will realize the O&M savings sooner and to a greater degree. The impacts of the LED Change-Out Program span across multiple departments at Avista. Operations is responsible for managing the work and executing the light change-outs in the field, primarily by Avista's servicemen and local reps. Avista's Operations Support Group (Mobile Dispatch) and Enterprise Asset Management (EAM) Technolog)/ are responsible for creating work orders for all 28,000 change- outs and dispatching them to the field. The Customer and Shared Services department, particularity Enterprise Systems - Customer Care & Billing (CC&B), is impacted by the project because the customer billing changes upon converting to LED light fixtures. For the LED Case, the implementation of converting to LED streetlights will require only one additional Full Time Employee (FTE) over a five year period. To remain with HPS streetlights, as in the Base Gase and Optimized HPS Case, will require no additional or new staffing. The entire alternative analysis report is attached for further detail. To summarize the overarching benefits of the LED Change-Out Program and the justification to begin the five year program sooner than later are the immediate energy savings and resource savings. Customers will benefit with every light changed out in the form of better lighting quality, reduced energy consumption and reduced labor cost. To delay the program is to delay the immediate savings to customers. The LED Change-Out Program is in alignment with the company's strategic vision of delivering reliable energy service and the choices that matter most to our customers.

This work is in suryort of the AMI project, 1.1 Steering Committee or Advisory Group lnformation The deterrnination for how the funds in this business case will be spent is a joint decision made by the Manager and General Foreman. A meter usage forecast will be used to guide the decision making process. The forecast will be based on the past five years of meter installs, current install rates, and manufacturer lead times. 2 BUS,,VESS PROBLEM The primary driver for this business case is failed plant and operations. We regularly experience failed plant when meters and/or metering equipment fails. Meters are a critical component to supplying our customers with electricity and to accurately measure their energy consumption. Please refer to Attachment 1 for the most recent meter failure analysis completed by Asset Management in early 2017. This analysis shows the failure curves for both digital and mechanical meters. The analysas suggests thatthe more digital meters that are installed the higherthe meter failure rate becomes. However, mechanical meters are no longer manufactured by our meter vendors because they have moved to the digital market. When meters fail at existing customer service point's immediate action must be taken to repair or replace the meter. This is because a failed meter will not provide accurate consumption data. Funding is necessary to replace or make needed repairs othenruise the customer billing data will have to be estimated. Billing estimation lowers the quality of service we provide our customers because estimated data can be viewed by the customer as inaccurate. Additionally, estimated billing data can put rate pressure on our customer base if usage is under estimated. lf usage is over estimated it unfairly penalizes the customer whose bill is being estimated. o o o Meter Minor Blanket Business Case Justification Narrative Exhibit No. g Page 1 of 6 Case No. AVU-E-19-04 H.

As you can see tabulated in the above table the lowest cost option is to fully fund this business case. The reduction in O&M is associated with the meter replacement portion of this business case. Historically there has been three solutions to replace failed meters: 1.) Refurbish and repair in house 2.) Return Merchandise Authorization (RMA) 3.) Replace failed meter with new meters 3.1 REFURBISH AND REPAIR IN HOUSE As Avista's population of digital meters grows and the mechanical meter population shrinks the less viable this option becomes. This is because digital meters require special equipment and training to repair, which is not available to our technicians. Also of note is that mechanical meters are no longer manufactured by our meter vendors because they have moved to the digital market. lt is very rare for our technicians to remove a mechanical meter from the field as a result of failure. The majority, if not all, of the rneter failures we experience in a given year are from the digital meter families. Table 1 shows how many digital and mechanical meters we have installed in WA and lD. This table also shows the average failure rate we experience annually. This option was not chosen due to the equipment and technical training required as well as the higher cost associated with the labor to refurbish meters.

Recent repair costs were quoted from our meter vendor to be between $20 and $40 dollars per meter. Table 3 shows the total cost to RMA a single meter. This cost was developed using very conservative values for each charge type and may be higher if more expensive (Poly-phase) meter types were included. This option was not chosen due to the high cost.

This is the lowest cost solution as shown in Table 4. There is a cost savings with new meters because there is no labor associated with refurbishing and testing and there is no RMA charges as compared to Options 1 and 2.

This information is reviewed with Asset Maintenance to establish an effective construction plan that prioritizes work based on faults and number of customer impacted. Asset Maintenance then collaborates with Electric Operations to coordinate the work. Asset Maintenance tracks the work budget, scope, and schedule. 2 BUSINESS PROBLEM The primary driver for the Underground Residential Development (URD) Cable Replacement Program is to improve system reliability by removing URD cable with a high failure rate. The other driver is to reduce O&M costs related to responding to customer outages caused by the failed cable. This work is needed to complete the replacement of the un-jacketed first generation underground primary distribution cable referred to as URD cable. This first generation URD cable was installed from 1 971 to 1982. There was over 6,000,000 feet of URD cable installed during this time period. Subsequent to installation the URD cable began to experience an increasing failure rate. From 1992 to 2005 the cable failure rates quadrupled from 2 faults to I faults per 10 miles of cable. The faults reached a peak of 238 annual failures in 2AO7. lncreased capital funding to replace this URD cable from 2005 through 2009 helped stabilize the failure rates. Continued funding and replacement of the cable has enabled a downward trend in failures as shown below in table 1. Cable installed after 1982 has not shown the high failure rate. This work is required to continue to reduce primary URD cable failures and increase reliability. Historically there have been over 200 cable faults per year. The average cost to respond to a fault in 2015 was about $3000 per event due to the challenging nature of the work to locate and repair the cable underground. The estimated remaining pre-l982 cable is around 1,000,000 circuit feet. H. Rosentrater, Avista Schedule 3,Page 42 of 186 o o o Primary URD Cable Replacement 2017 Cody Krogh o Primary URD Cable Replacement 2017 The tables below demonstrate the effectiveness of this program to reduce faults and outage expenses through the replacement of the defective cable.

There is also some analytics/engineering to identify remaining cable segment locations. Given the projected low capital spend level, the majority of the construction labor will be performed by Avista Crews. Contract crews are typically used to plow in the cable, bore conduit or trench and install conduit in the trench. Avista crews then pullthe cable into the conduit and complete the installation. The Do Nothing approach presents significant reliability risk and added O&M cost. The historic positive results from the URD cable replacement program shown above in section two provide strong justification for continuing the current funding plan. Over 6,000,000 feet of URD was installed before 1982. Programmed replacement of the problem cable has been on-going at varying funding levels. The estimated remaining pre-1982 cable is around 1,000,000 circuit feet. At the current proposed funding rate of $1M per year this program is planned for the next 20 years. Reduced funding would extend this time and result in additional outages and O&M expenses. The URD Cable Replacement Program aligns with Avista's strategic vision by increasing reliability to the electric distribution system. Safe and Reliable infrastructure is the focus area for this program. The projected annual capital spend of $1M per year is reasonable based on the realized reduction in faults from previous work and this spend level enables continued replacement of the high failure rate cable. Repair of the cable has not shown to be cost effective because the cable typically faults in another location. Avista customers will be positively impacted by this program by realizing fewer outages from the URD cable failure. This results in improved system reliability. Avista electric operations is positively impacted through converting this work to planned work that enables more efficient use of labor. lt also reduces O&M expenses. Asset Management is responsible for tracking URD cable outages from Outage Management Tool (OMT) and tracking replacement locations and cost. The Asset Maintenance group is responsible for identifying cable segments and managing the coordination of work. H.

This business case provides for replacement of existing technology in alignment with manufacturer product roadmaps for application and technology Iifecycles, as well as for deployment of new applications and technology as required to address expanding regulatory and business requirements. Technology continucs to change and T&D Systems continue to incorporate improved technology. The primary driver for this business case is to maintain and improve our real-time T&D System Operations, upgrading and replacing systems as they become outdated and obsolete. Many projects within this business case replace or upgrade equipment to meet mandatory obligations required by the Federal Energy Regulalory Cornmission (FERC), North American Electric Reliability Corporation (NERC), and the US Pipeline and Hazardous Materials Salbty Administration (PHMSA). Other projects replace existing fhiled or failing equipment to maintain operability.

Control algorithms are optimized to minimize unnecessary mechanical stress while maximizing compliance with control requirements. o Gas Operations - Gas Controllers nronitor gas system conditions around-the-clock.'they direct field crews. maintain system integrity, and respond to abnormal conditions. Controllers respond to emergency situations. o Critical lnfrastructure Protection - Numerous protection measures arc deployed to protect critical systems from unauthorized physical and electronic access. NERC standards have dozens of requirements regarding protection of critical infrastructurc. In-depth and lengthy audits are perfonned every three years by the regional reliability organization, the Western Electricity Coordinating Council. Potentially significant financial penalties result from any instances of non-compliance. o NERC reliability standards are being continually changed. New and changed standards are adopted which will address emergency operations, transmission operations, critical infrastructure protection, communications, and balancing authority operations. 3 PROPOSAL AND RECOMMENDED SOLUTION Optlon Gapltal Coet Start Complete Do nothing $o Fully funded 'SCADA - SOO and BuCC" business case $920,000 0112018 12t2018 This program (Supervisory Control and Data Acquisition - System Operations Office arrd Backup Control Ccnter) replaces and upgrades existing electric and gas control center telecommunications and computing systems as they reach the end ol'their useful lives, require increased capacity, or cannol accommodate necessary equipment upgrades due to existing constraints. Included are hardware, soliware, and operating system replacement and upgrades, as well as deployment of additional capabilities to satisfy new operational stalrdards and requirements. Some systern upgrades may bc necessitated by other requiremenls. including NEITC reliability standards. federal gas standards. systern growth. and external projects (e.g. Srnart Grid). There are multiple risks il-this program is not adequately funeled. The clearest risk would be to public and personnel safety.

Additionally there is significant compliance risk. l'hese control systems provide the capabilities required to achieve compliance with numerous reliability standards and requirements. For the electrical system these include the NERC standards BAL, COM, CIP, EOP, INT, PER, PRC, TOP, and VAR. Forthe gas system these include the PHMSA "Pipeline Safety: Control Room Management/Human Factors" rule (49 CFR Parts 192 and 195.) The expenditure of these funds is necessary to operate Avista's electric and gas systems in a safe, reliable, and conrpliant manner. The "Do Nothing" option was considered. This business case addresses the need to provide the technical capabilities and tools to remotely monitor and control our electric and gas infrastructure. The systems which accomplish this are integral to meeting our responsibilities to ensure public and personnel safety, monitor and respond to system conditions, protect equipment, and protect from cyber threats. These systems need to be periodically upgraded and expanded to continue to meet existing and new requirements. There is really no responsible "alternative" to this business case. ln addition to the risks related to public and personnel safety, compliance risk would be increased without this investment. Non-compliant operational capabilities and practices would result in negative audit findings, significant financial penalties, and litigation expenses. Obsolete equipment would remain in service until failure. Additional capacity for growth may or may not be suitable for required expansions to meet other needs (e.g. Regulatory, Smart Grid.) Further justification of the need of this business case is listed below. o There are numerous mandates in effect which compel these expenditures, numerous NERC Standards, and PHMSA's Control Room Managernent rule, in particular (49 CFR Parts 192 and 195). o There is no practical risk mitigation should we fail to meet these requirements. o This is a conlinuous program. Work is started and completed throughout each year. and in some cases, such as major upgrades, spans multiple years. o This business case is crucial in a key aspect of Our Vision; "l)elivering reliable energy service..." Il is essential in providing suflicient control center technology tools, situational awarcness, and monitor/control capabilities to achieve reliable energy service. o l'his business case is key in accomplishing the Our Focus item of "Safe & Iteliable Infrastructure."

The work is unplanned and non-specific in nature, but occurs regularly and historicalaverages are used to estimate an annualquantity. ln the event of larger scale storms, like the historical storm event in November 2015, a formal lncident Command System (lCS) is created to manage the resources needed to respond. 2 BUSINESS PROBLEM The electric storm business case is driven by restoring Avista's transmission, substation, and distribution systems (damaged plant) into serviceable condition during a weather storm event where assets are damaged. Storm events are random and often with short notice. The business case of Storms is funding a rapid response to unplanned damages and outages so customer outages are minimized. The business provides funds for replacing poles, cross arms, conductor, transformers, and all other defined retirement units damaged during storm events. The damage can be due to high winds, heavy ice and snow loads, lightning strikes, flooding, or wildfires. The importance of quickly replacing damaged facility is vital to providing reliable service to our customers. The annual budget amount is determined based on historical average experience rate of Capital restoration work. 3 PROPOSAL AND RECOMMENDED SOLUTION Option CapitalCost Start Complete Unfunded $0 Fully Funded $3,090,000M Continuous Program Figure 1 shows the historical costs (2005 - 2016) for the distribution storm business.

The Engineering Roundtable is comprised of representatives from the following departments: Asset Maintenance, Asset Management, Compliance, System Planning, System Operations, Telecommunications, Transmission Contracts, Protection Engineering, Substation Engineering, Transmission Engineering, and Substation Support. 2 BUSINESS PROBLEM Replacing and upgrading major substation apparatus and equipment as it approaches end of life or becomes obsolete is necessary to maintain safe and reliable operation of Avista's transmission and distribution systems. Rebuilding significant portions of stations may be necessaryto accommodate the replacement of failing or obsolete equipment since new standard-use apparatus and equipment is often of higher capacity and newer technology and may need to meet updated equipment spacing and operating standards. While asset condition is the primary driver triggering the need to replace major apparatus and equipment, additional factors that may contribute to the need to broaden the scope of a station rebuild project include operational and maintenance requirements, updated design and construction standards, SCADA communications, future customer load-service needs, and other programs (e.9. Grid Modernization). Future complete station rebuilds and/or replacements will be outside the scope of this business case and will be addressed individually. Major apparatus include high-voltage circuit breakers, lower voltage circuit breakers and reclosers, circuit switchers, capacitor banks, powertransformers and step voltage regulators. Associated equipment includes relays, meters, surge arrestors, station rock and fencing, panel houses, instrument transformers, high- voltage fuses, air switches, autotransformer diagnostic equipment, batteries and chargers, and panel houses.

The environmental team tests and tracks PCB level of each transformer by location. This information is reviewed with Asset Maintenance to establish an effective replacement program that prioritizes work based on environmental risk and reliability. Asset Maintenance manages the program and collaborates with Electric Operations and contractors to coordinate the work. Asset Maintenance tracks the work budget, scope, and schedule. 2 BUSINESS PROBLEM The Transformer Change-Out Program (TCOP) work has three primary drivers. First, the pre-1981 distribution transformers that are targeted for replacement average 44 years of age. Their replacement will increase the reliability and availability of the system. Secondly, the transformers to be replaced are inefficient compared to current standards and their replacement will result in energy savings. Thirdly, pre-1981 transformers have the potentialto have Polychlorinated Biphenyls (PCB) containing oil. The TCOP Program was implemented in 2011. The Program has focused on eliminating alltransformers containing or potentially containing PCBs. The initialtarget was on areas near the Spokane and Pend Oreille River watersheds and has now moved to all transformers containing PCBs. These transformers have specific work plans for removing them from the system. These PCB targeted transformers are on schedule to be replaced by 2019. The second phase of the Program is to replace all remaining pre-1981 transformers through the use of the Wood Pole Management Program. This work is planned to be complete by 2040 based on the current funding request. PCBs and PCB wastes are regulated by both the Washington Department of Ecology (Ecology), through the Dangerous Waste Regulations, Chapter 173-303 WAC, and by the U.S. Environmental Protection Agency (EPA) under 40 CFR Part 761, the Toxic Substances Control Act (TSCA). The transformers to be removed early in the program are those that are most likely to have PCB containing oil and their replacement will reduce Efilblt No. u case No. AVU-E-19-04 Page 1 0f I H.

There has also been an increased focus on PCBs and similar contaminants by local, regional, and national initiatives. On April 10,2010, the EPA had issued an Advanced Notice of Proposed Rulemaking (ANPR) on new PCB regulations. Washington State Ecology created an "urban waters initiative" to investigate persistentand bio-accumulative toxics; this initiative included the Spokane River watershed. The Spokane River is listed on the Clean Water Act "impaired" list for PCB contamination. The City of Spokane began a storm water study to find and reduce sources of PCBs in its storm water system. ln addition, PCB cleanup is very difficult in any environment and nearly impossible in aqueous environments. These and other efforts reflect how important it is to keep PCBs from entering the environment. As a result, Avista is determined to aggressively remove PCBs from its electricaldistribution system in a disciplined manner. Currently, there are 906 transformers remaining in our system that are known or predicted to contain a PCB level greater than 1 part per million. ln addition, there are 1,098 underground transformers that have been predicted to not contain PCBs (predicted non- detect) however, no actual tests have been conducted on these transformers. These transformers were analyzed using Serial Number Sequencing (SNS) where transformers with similar serial numbers were assumed to have similar PCB levels. Serial Number Sequencing is more cost effective versus PCB testing the pre-1981 transformers in the field. The predicted non-detect transformers do run a risk of containing some level of PCBs. The table below reveals the replacement plans for the targeted transformers in the immediate future. This is the sixth year of replacing the targeted (PCB containing) distribution transformers. When the program began in 2011, there were over 12,000 targeted transformers. Currently, 7o/o of the 12,000 are remaining.

The optimal replacement age of a transformer is M years old. The failure of an aging transformer results in an outage for the downstream customers. The chart below shows the positive reduction in outages as a result of this Program. Note that overhead transformer outages have been reduced nearly 60% between 2007 (approximately 250 outage events) and 2016 (approximately 100 outage events). There is a customer impact value of $5,600 per event according to the U.S. Department of Energy's lnterruption Cost Estimate (lCE) Calculator.

Rosentrater, Avista Schedule 3, Page 71 of 186 - Another significant driver for the TCOP program is energy efficiency and cost savings. A component of Washington State lnitiative l-937 is to undertake cost-effective energy conservation. To fulfillthis requirement, sources of efficiencywere identified. Distribution transformers are one of the identified groups of assets where efficiency can be gained by replacing dated models with newer models that do not lose as much energy while in an unloaded state. Upon replacement of all pre-1981 transformers, there is an expected energy savings of 5.6 MW per hour. According to Asset Management this represents a savings of $215 per hour and contributes to an estimated lnternal Rate of Return (!RR) of 8.24o/o. The key metrics of the program are to replace the targeted transformers and achieve energy savings, which results in increased reliability. The table below reflects the results tracked for the program.

Cost and timing dependent on when programs address feeders with PCB transformers ln order for the Distribution Transformer Change-Out Program to be successful, design resources are needed to complete field assessments and designs. Contract construction crews are also necessary to supplement Avista's Electric Operation resources. Pole inspection support from the Wood Pole Management group is also required to ensure the safety of the pole prior to any construction work. This Program has been funded since 2011. The current approach is considered the best solution for mitigating environmental risk and for dollar efficiency. There are alternatives that consider different implementation schedules. One alternative is to remove overhead PCB containing and other pre-1981 transformers through the Wood Pole Management program. This alternatives does have some efficiencies because it involves a crew visiting a pole one time to address multiple issues. Additionalfunding would be required for Wood Pole Management to conduct this increase in scope. Another program to address the underground transformers would also be needed. The time to replace all, would be approximately 20 years. Underground transformers run a greater risk of leaking and not detecting those leaks. This is motivation to replace those transformers in a shorter time period. Another alternative discussed was to replace the targeted transformers "as we get there". ln other words, if work is occurring at a site where a targeted transformer is located, the transformer would be replaced at that time. This method could be considered efficient by the same reasons as using the Wood Pole Management approach with a crew visiting a location one time however, this approach would take a minirnum of 12A years to replace alltargeted transformers. This increases the risks of spills and/or failures. o Business Case Justification Narrative m case No. AVU-E-19-04 Page 5 0f I H. Rosentrater, Avista Schedule 3, Page 73 of 186 Distribution Transformer Change Out Program 2017 ln addition to the risks of outages and failures with the aging equipment, the additional risks associated with this program pertain to the following: Environmental: Risks include; large volume transformer oil spill, difficult hazardous waste cleanup, moderate to low volume or level of PCBs, minimal impact to watenrvays, repeated or moderate air emission exceedance. lf the program is unfunded the potential occurrence is greater than 4 spills per year. lf funded, the potential occurrence is less than 1 per 50 years.

If the program is unfunded, the potential occurrence is less than 1 per 10 years. lf funded the potential occurrence is less than 1 per 50 years. The entire population of pre-1981 transformers total nearly 47,000 units. The first phase of targeted PCB transformers (approximately 12,000) is expected to be complete by 2019. The second phase of the program is to replace the remaining pre-1981 transformers (Predicted Non-Detect and Actual Non-Detect). This work is expected to extend 1o2040.

The 230 kV breakers are the Westinghouse oil circuit breakers with a name plate interrupting duty of 12.5 kA. The maximum 3-phase short circuit calculated at Noxon Rapids is 14.31 kA. Since the limiting ratings are both an urgent safety and reliability issue new breakers wcre ordcred in early 2016. Avista has taken delivery of the new Mitsubishi 230 kV type "F" SF6 breakers. l'he new breakers are capable of intemrpting fault currents of 40 kA and operating at steady state voltages of 253 kV. The Mitsubishi type "F" circuit breaker represents the new standard 230 kV design breaker for Avista. Completion of this project is required to mitigate a deficiency identified by TPL-001-4 and to ensure compliance with the NERC standard. 3 PROPOSAL AND RECOMMENDED SOLUTION o Optlon CapitalCost Start Gomplete Alt 1: Status Quo $0 Alt 2: Fault Reduction Scheme Alt 3: Tie Breaker to be operated normally open Alt 4: Reduce generation at Noxon Rapids HED Alt 5: Construct DBDB Sfation at Noxon Rapids Alt 6: Replace (6) limiting breakers (plus OCB Tie Breaker) within existing switchyard $4M 2017 2018 Business Case Justification Narrative Exhibit No. 8 Page 1 of 3 Case No. AVU-E-19-04 H. Rosentrater, Avista Schedule 3, Page 77 of I 86 Alternative I -Stalus Ouo/Do Nothine: This alternative is not recommended because it does not mitigate the safety and operational issues associated with over-dutied equipment within a station. Alternative 2 - Fault Reduction Scheme: This alternative is not recommended because the fault current at the Noxon 230kV Station, after opening a remote breaker, remains greater than the nameplate interrupting duty of the Noxon 230kV circuit breakers. This alternative also does not follow standard industry practices for distance relaying settings. Alternalive 3 - Tie Breaker Onerated Normallv Ooen: This alternative is not recommended because this operating condition will affect neighboring parties. This will isolate Avista's generating units on the bus tied to BPA's transmission system with no normally closed transmission path to integrate Avista's generation onto the Avista transmission system. It will also isolate Avista's new 230kV reactors on the BPA system, thereby leaving no reactive control tied to Avista's 230kV transmission system. Extensive studies for the Montana-to-Northwest transmission path will need to be addressed with affected transmission entities through a WECC process. Alternative 4 - Reduce Generation at Noxon Raoids HED: This alternative is not recommended because the ground fault current at the Noxon 230kV Station would remain too high. The only way to get the fault curent low enough is to disconnect the Noxon generator step-up transformers at the station which would leave the entire station out of service. Also, Noxon Unit No. 5 is typically used for operating reserves and reserve sharing, which would be eliminated with the station out of service. Eliminating this generation capability would be costly and infeasible. Alternative 5 - Conslruct DBDB Station: This alternative mitigates all issues but is presently not recommended due to its longer lead time to construct. The over-dutied circuit breakers are a current safety issue and need to be addressed immediately. The Noxon Switchyard Rebuild project alternative remains necessary due to asset condition and poor operational flexibility with the current station configuration, impacting both the Avista and BPA transmission systems. Alternalive 6 - Reolace Over-Dutied Breokers in Exislirts Stuitchvard: This alternative is the least-cost effective option to immediately address the safcty and operational issues by providing sufficient fault-interrupting capability at Noxon 23OkV Station. This altemative also mitigates identified NERC TPL-001-4 R 2.3 dehciencies in the 2016 Planning Annual Assessment. Solution: Alternative 6: Transmission Planning recommends replacing the six limiting breakers within the existing switchyard. In addition, the oil filled HV Bus Tie Breaker will also be replaced, bringing the total number to seven (7): Replace 3 breakers, R334, R332, and R336 at Noxon Rapids Station in Fall of 2017 Replace remaining 4 breakers at Noxon Rapids Station in 2018 o o o Noxon 230kV Switchyard HV Breaker Replacement Business Case Justification Narrative Exhibit No. 3 Page 2 of 3 CaseNo. AVU-E-19-04 H.

The methodology of Attachment A of the NERC standard was performed to identify the affected buses within the Avista BES. The Protection Systems must be capable of recording electrical quantities for each BES Elements it owns connected to the BES buses identified. The present Protection Systems are either electromechanical or first generation relays not capable of meeting the NERC PRC-002-2 standard requirements of fault recording. The scope of the project is to upgrade the existing Protection Systems on various 230 kV and 1 1skv terminals to Fault Recording (FR) capability per PRC- 002 requirements at Beacon, Boulder, Rathdrum, Cabinet Gorge, North Lewiston, Lolo, Pine Creek, Shawnee, and Westside. lmplementation is a phased approach with 50% complaint within 4 years and fully compliant within 6 years of the effective date711116.

The Point of Interconnection (POf will be the new 3-position ring bus Neilson Substation with a line position dedicated to the Interconnection Customer. The Interconnection Customer chose the POI from a number of options developed by Avista's Transmission Planning Group during the FERC- mandated interconnection study process. Per the FERC process, the Interconnection Customer and Avista have signed an Interconnection Agreement that include required milestones for completion of this project. These rnilestones include, the Interconnection Customer providing deposits totaling $1,041.500 (equivalent to the project's associated Direct Assigned Costs) in the 2018- 2019 time frame, and Avista's completion of the project with an in service date prior to Septernber 30,2020. 3 PROPOSAL AND RECOMMENDED SOLUTION Option CapitalGost Start Complete Alt 1: Status Quo: Do nothing.

BUSINESS PROBLEM There is an ongoing issue with high voltage on the 230 kV transmission system inthe Lewiston/Clarkston area. The high voltage problem is persistent most months of the year (the exception is heavy sunmer loading months) and the high voltage peaks during the overnight hours. This high voltage condition is a result of the expansion of Avista's 230 kV transmission network. Although there are many benefits to a large networked transmission system, one negative outcome is that long, lightly loaded transmission lines produce large amounts of line charging current (leading reactive MVAR), which increases system voltage. Currently, there is no practical way to correct this high voltage issue with the existing 230 kV transmission system beyond taking lines out of service. 3.

As load demands increase and customer expectations rise regarding reliability, incremental distribution substation capacity is required. This allows for improved operational flexibility, better system reliability, and easier routine maintenance scheduling as equipment is more easily taken out of service because load can be transferred. 3 PROPOSAL AND RECOMMENDED SOLUTION Optlon Capltal Gost Start Complete Do nothing $0 Recommended Solution $6M This program adds new distribution substations to the system in order to serve new and growing load as well as for increased system reliability and operational flexibility. New substations under this program will require planning and operational studies, justifications, and approved Project Diagrams prior to funding. Alternatives considered include : o Do Nothing: Maintain (to the best of our ability) all obsolete or end-of-life apparatus. Repair or replace equipment on emergency basis only. Some repairs would not be possible due to obsolescence. Considerably more, and longer, customer outages would result. Although there is zero Capital cost connected with keeping the status quo there are some associated O&M and other system sustainment costs.

Factors such as operational issues, ease of access during outages, and potential for communications build-out are also considered in prioritizing this work. A relevant metric to this business case is the Probability, Consequence, and Risk Summary developed by the Asset Management group, which indicates which transmission lines are most in need of replacement due to end-of-life indicators. This list changes on an annual basis based on the work performed under this business case in the previous year. Another relevant metric is the System Operator's Log with a focus on tracking the number of outages related to asset failures. 3 PROPOSAL AND RECOMMENDED SOLUTION Option Caplta!

There are no expected business impacts (such as staffing, etc.) to continue the program in place as it was split off of an existing business case. Without replacing old and worn-out poles and cross-arms, our system will be increasing in risk for more failures and more risk of a major fire caused by a failure. As time moves fonrard, the number of failures and risk of a major fire will increase the difference in costs between doing nothing and continuing the Transmission Major Rebuild - Asset Condition program. Transmission outages can have significant consequences as they tend to impact a large number of customers and have the potentialto start fires in dry areas. Transfers to plant will typically occur lightly over a May-June timeframe for work that can be completed in the spring, and heavily in the October-December timeframe for work that has to be completed in the fall. Most of the work is typically completed in fall months due to access conditions and availability of outage windows. This business case aligns with the organization's mission to deliver reliable energy service to customers by preventing the degradation of reliability of transmission service to the substations that serve them. lnternal stakeholders in this business case include all of the departments listed in the Steering Committee section. Option 1: Do nothing - Not recommended Option 2: According to Avista's Transmission System Asset Management Plan, "The 30-year replacement period is recommended at $21.1 million per year, split between $11.3 million for 11SkV and $9.8 million for 230kV. This policy, when coupled with an ongoing, annual risk assessment and targeting of funds, over the long term will effectively reduce risks and minimize total lifecycle costs". Option 3: Current funding level - Current spending on the Asset Condition risk category is $9.45 million annually. Funding levels will be reviewed on an annual basis.

During routinely scheduled inspections, issues are discovered regarding the condition of assets, including items such as rotten poles, broken/spliUroften crossarms, broken conductor or ground/shield wire, and air switches that no longer operate safely or reliably. A relevant metric to this business case is the System Operator's Log, with a focus on tracking the number of outages related to asset failures. This number would be expected to increase over time if this program is not funded.

This program was undertaken in response to the October 7, 2012 North American Electric Reliability Corporations (NERC) "NERC Alert" - Recommendation to lndustry, "Consideration of Actual Field Conditions in Determination of Facility Ratings". This Capita! Program covers mitigation work on Avista's "Low Priority" 230kV and 115kV transmission lines. Mitigation brings lines in compliance with the National Electric Safety Code (NESC) minimum clearances values. These code minimums have also been adopted into the State of Washington's Administrative Code WAC). This program is expected to be completed in2020. The lines that were found to have clearance discrepancies were categorized High, Medium, and Low Priority based on the following criteria: . High: Bulk Grid 230 kV linking Avista generation to primary load . Medium: Remaining 230 kV lines, and 11skv lines linking Avista generation to primary load . Low: Remaining 115 kV lines A relevant metric to this business case can be found in the NERC Alert Mitigation spreadsheet maintained by Avista's Reliability & Compliance Manager, which shows the status of mitigation work completed and work outstanding.o Business Case Justification Narrative Exhibit No. 8 paoe 1 of 3 Case No. AVU-E-19-04 H.

The Advisory Group is our Native American Relations department, who negotiates easements and settlements with the individual Native American Tribes. Projects are driven by any installation or rebuild of facility on Tribal lands. The Native American Relations department meets with Tribal representatives to negotiate easements, or modification of easements in conjunction with construction projects. 2 BUSINESS PROBLEM o o This business case is driven by compliance, the legal requirement to obtain and maintain easements for our transmission and distribution lines. This is required under Part 25 of the Code of Federal Regulations, Section 169. Several of these cross Native American Tribal land, requiring us to maintain easements or fees to occupy those areas. The Native American Relations department of Avista is the interface with the Tribes, and conducts negotiations on behalf of Avista. Failure to maintain easements would put us in immediate violation of Federal Law. We would be required, lacking an easement, to remove our facility from Tribal land. Many of our easements are for transmission lines, therefore this is not a viable option. The primary measure would be to have active easements on all Tribal encroachments. Currently, Avista maintains 81.7 miles of transmission lines on Tribal land. 3 PROPOSAL AND RECOMMENDED SOLUTION a a Optlon CapltalCost Start Complete Do nothing $0 Continue to negotiate easements as required $300,000 01 2017 122099 Business Case Justification Narrative o Exhibit No. 8 page 1 of 3 Case No. AVU-E- l9-04 H.

The Engineering Roundtable is comprised of representatives from the following departments: Asset Maintenance, Asset Management, Compliance, System Planning, System Operations, Telecommunications, Transmission Contracts, Protection Engineering, Substation Engineering, Transmission Engineering, and Substation Support. 2 BUSINESS PROBLEM The Transmission Construction Compliance Business Case covers the Transmission rebuild and reconductor work necessary to maintain compliance with the NERC Reliability Standard TPL-0014 - Transmission System Planning Performance Requirements ("Standard"). This standard mandates that an annual planning assessment be conducted and corrective actions be identified and implemented to remedy any system performance deficiencies. Corrective Action Plans must be completed within the required timeframe to meet the system performance requirements dictated by the Standard. The implementation of this business case will be considered successful if these projects are all completed prior to the required compliance dates identified in the Engineering Roundtable Project List, which are copied from the Corrective Action Plans (within the annually published Avista System Planning Assessment).

Asset lifecycle replacements are compiled by Facilities and are based on an asset condition report and industry recognized lifecycles. Site improvement projects are approved based on productivity and/or business need. ln 2011, Facilities prepared a survey of several of our existing sites that created an Asset Condition score. This survey is the basis for prioritizing asset lifecycle replacements and site improvement projects (See attached for survey results). A new site assessment survey is currently underway with an independent contractor and should be completed in 2017 - This will be the basis for the asset replaement program over the next 10 years.

Most of our building systems are also past their recommended life based on recognized industry standards defined by Building Owners and Managers Association (BOMA), and lnternational Facility Management Association (IFMA) and are requiring renovation or replacement. Many of the origina! campus layouts and buildings at our Service centers are no longer optimaltoday due to changes in our vehicle sizes, materials storage, and operations flow. These changes have required the need for project funding to address changing business and site requirements as well. Average funding splits based on proiect priorities This program is be responsible for the capital maintenance, site improvement, and furniture budgets at over 40 Avista offices, storage buildings, and service centers (over 900,000 total square feet) Companywide. This program is intended to systematically address the following needs: . Lifecycle asset replacements (examples: roofing, asphalt, electrical, plumbing) o Lifecycle furniture replacements and new furnilure additions (to support growth) .

Safety, compliance, and productivity requests are rated highest and given priority first. Many of these replacements can create safety risk if not addressed (sidewalks, structural repairs). Not systematically addressing maintenance needs could ultimately result in complete replacement of the buildings at some point. This Structures and lmprovements program will be made up of 3 main parts: 1. Capital Asset Replacements ER 7001 This portion of the Structures and lmprovements Program is based on the results of the Facilities Condition Assessment Survey. This survey willtake into account the condition and lifecycle of each Facilities asset. Assets will be graded and those requiring replacement within the next 10 years will be estimated and scheduled for replacement at an appropriate year during the 10 year time frame of the survey. Buildings as a whole will be assigned a Facilities Condition lndex (FCl) as part of the survey to help compare future capital needs and drive the decision of continued capital expenditures vs. possible replacement. o o Optlon Caplta!

Business Additions or Site lmprovements ER 7001 This portion of the program is intended to support site improvement requests and productivity or business-related needs. Project requests are made by Operations site managers in June the year before. The list is then vetted for validity and business need by director-level management. Approved projects are then prioritized vs. capital asset replacement priorities, and assigned per available capitalfunding. Projects that are tied to compliance, safety, or productivity will be given funding preference. Example (security fencing and gate, weld shop crane): A robust operations and maintenance program will be required to help further extend the lifecycle of our Facilities assets and help to lessen capital replacement needs. Conversely, limited O&M maintenance programs will result in shorter than standard asset lifecycles, and ultimately increased Capital spending. As the condition of our Facilities improve, capita! asset replacements should lessen in future years of the program. This is again dependent on sufficient O&M maintenance budgets and workforce. The majority of projects in the Facilities Structures and lmprovements program begin work in the 2nd or 3'd quarter of each year, and will usually transfer to plant before the end of the year. Some of the larger projects, or projects with extensive design, can carry over to the following year. Option 2 - Partiallv Fund Proaram based on orioritv This option would decrease the capital program and increase existing O&M budgets to prolong structures' lifecycles beyond rated life, and reduce capital needs. This option is not the prefened approach over the long-term. Capital investments can be limited with a corresponding increase in O&M dollars. As building systems continue to decline O&M burden will increase. Business site improvement requests are intended to address changing business needs. These projects are usually linked to an enhanced productivity outcome.

When the budget needs to be reduced, reductions are first made to requests in this category. Replacement is intended to replace aging units to achieve more predictable capital requirements and avoid replacement peaks caused by large-scale failures. Cutting into these requests over an extended period could lead to reduced efficiency and have safety impacts. Ootion3-Donothino This option is not recommended.

Midway through every year, business units analyze their need for tools and equipment to be purchased during the next fiscal year. Each year the Capital Tool Program has more requests for tools and equipment than can be funded (see Figure 1). The requests are prioritized by Safety and Compliance, Replacement, or Enhanced Productivity categories. Cuts to the requests are made by the business units to bring the projected cost of the list of equipment and tools into line with the budgeted amount, Review of the request is performed by Avista's CPG who may modify the funding level for the program in concert with other business budget needs. Additiona! cuts by the business units to the Tools and Equipment budget may be needed to meet the revised budget.

The approval process follows the management chain of Supply Chain Manager, Manager of Shared Services, Vice-President of Energy Delivery, and President of Avista Utilities. The CapitalTools Program does not have a steering committee but does have stakeholders who are the managers and directors of all departments. 2 BUSINESS PROBLEM Avista's Capital Tool Program provides all departments the proper tooling and equipment to perform work safely and efficiently. This equipment is necessary to safely construct, monitor, ensure system integrity, and properly repair and maintain the Avista systems (electric, gas, communications, fleet, facilities, and generation). Tool and equipment purchases are prioritized based on three categories: 1. Safety and Compliance 2. Replacements 3. Enhanced Productivity (see Figure 2) 2OL4-2OL6 Tools and Equipment Purchased Safety and Compliance, 132,27% Enhanced Productivity, 28?,570.4 Replacement, 80, t6% Figure 2 The highest priority tool and equipment purchases help ensure that Avista meets all safety and compliance requirements. Changes to safety standards and new compliance mandates may require purchasing new tools.

Avista employees must be able to rely on this equipment while performing hazardous duties, and must be confident that the equipment will perform safely and efficiently. Failed equipment can lead to hazardous conditions for the operators, potentially causing injury or death. Much of the capitalequipment used in the utility industry is very specialized and may not be readily available due to long lead times. This equipment needs to be fully functional and available, for planned work as well as emergency outage repairs on our facilities and equipment. Equipment failures cause slowdowns in work performance. Examples of tools and equipment purchased for replacement reasons are: . Replacement of telecommunications equipment when the current platform is no longer supported. Aged gas boring moles that can no longer be rebuilto Underground locating equipment when replacement parts are no longer available for repairs The third and last category for prioritizing tool and equipment purchases is enhanced productivity. Capitaltooling and equipment is used to perform new construction work or repair work for unplanned failures. Ofien this work can take less time or be completed with better results by using tools. This category also includes material handling and storage equipment for company storerooms (forklift, storage cabinets, racking, etc.) Equipment for storerooms increases warehouse response and efficiency to crews in providing the needed material or tool in a timely manner. Examples of tools and equipment purchased for enhanced productivity are: o Purchase of new underground locators, which serve as a cable locator and fault finder- previously these were separate pieces of equipmento Plasma metal cufting table so Generation can machine their own parts onsiteo IKE field data collection device used to efficiently design, capture mapping information, and field audit overhead assetso Fiber optic fusion splicing trailer to allow technicians to splice in all climates/conditions a Business Case Justification Narrative Exhibit No. 8 Page 3 of 7 CaseNo. AVU-E-19-04 H.

Due to the specialized nature of utility equipment, it is most efficient for Avista to equip employees with the necessary tools and equipment to safely perform timely emergency repairs, while using the same tools and equipment to perform ongoing scheduled work and maintenance. Furthermore, this specialized equipment is often only available directly from the manufacturer, and is not typically available as a rental. By funding this program, Avista ensures that employees have the proper equipment to safely and efficiently perform their work, while providing safe, reliable service to customers. o o O Capital Tools & Sfores Business Case Justification Narrative Exhibit No. 8 paoe 4 of 7 Case No. AVU-E- l 9-04 H. Rosentrater, Avista Schedule 3, Page 124 of 186 Option 2- Partiallv Fund Prooram based on prioritv This option is not the preferred approach over the long-term, however it is exercised when necessary. Each year when the requests for tools and equipment are submitted, cuts to Capital Tool program are made by the business units to bring the projected cost of the list of equipment and tools into line with the budgeted amount. Further modification of the funding level for the program is performed in concert with other business budget needs. When the budget needs to be reduced, reductions are first made to requests in the category of enhanced productivity, then replacement. Replacement is intended to replace aging units to achieve more predictable capital requirements and avoid replacement peaks caused by large-scale failures. Cufting into these requests over an extended period could lead to reduced efficiency and have safety impacts. Having the ability to test and incorporate equipment that falls within the enhanced productivity category can help support improved processes and lead to enhanced safety and longer equipment lifecycles. Capital lools & Sfores o o o Ootion 3 - Rent Eouiomant Renting a percentage of the capital equipment was considered as a possible altemative. Of the 430 items purchased firom20121o2014,233 can be rented, although 216 out of the 233 items are needed on hand at alltimes for emergency locates and repairs. This leaves 17 possible items, or 4o/o of the totalequipment, which qualifies as potential rentalequipment (see Figure 3). lf equipment is rented, there is no guarantee of availability. Rental companies rent equipment on a first-come, first-serve basis, making equipment scheduling for specific time sensitive jobs very difficult. Safety and compliance regulations are also affected when correct equipment is not available for rent. Equipment failure is often a con@rn with rental equipment, as it is uncertain what condition rentalequipment is in, or how it has previously been maintained. This can lead to safety issues for equipment operators when failures occur, as well as lost production time. Depending on the timeline of the rental equipment, it would not be cost effective to rent long-term as the rental costs would exceed the base price of new equipment. An average rentral price for a basic cable locator is $450/month, which equates to $5,400/year. The 2017 purehase price of this item is $3,700. 2012-2014 Renta I Possi bi llty Not Needed for Emergencies, t7,4yo Figure 3 Training on rental equipment would also be required, if different than standardized Avista equipment.

Rosentrater, Avista Schedule 3, Page 128 of 186 Campus Repurposing Phase 2o o o a Alignment of campus parking and number of employees based at main Gampus The Avista corporate campus comprises 28 acres located next to the Spokane River in heart of the Logan Neighborhood. The campus in just north of the downtown Spokane corridor. Avista also owns eight additional acres of property directly adjacent to the campus at the north end. This parcel is separated from the main campus by North Center Street (a main city arterial). Avista's corporate campus footprint is currently bound to the east by the Spokane River, and to the west and south by the Mission Park and Burlington Northern Railroad, leaving minimalflexibility to manage company parking, employee and materials space needs. The Avista corporate campus was built in 1958 to consolidate and house all utility operations that were at that time spread throughout the community. As business needs changed over time, one-off expansion projects were to reactively address changes in business need. Employee grov'rth and materials storage increases through the years have created the need to locate employees and materials at offsite locations, requiring space leases and other non-optimal solutions to meet growing company space needs.

The final properties between Avista and the neighboring Riverview Retirement Community were purchased in2O14, now allowing us to develop them for company use. The decision was made in 2011 to take a holistic approach to these issues and create a single proposed solution for the Corporate Campus that would address current issues, and future needs. The campus repurposing planning group began working in 2011 to find a way to address the growing employee space needs, parking issues, campus materials storage issues, safety and traffic flow issues (Operations traffic and employee traffic mixing), as well as look into addressing the changing business needs of our vehicle fleet and operational processes. The result of this approach is a total campus plan that repurposes the existing campus for the next 50 years, minimizing our reactive approach and ensuring the best long term results for the Company and Ratepayers. 3. PROPOSAL AND RECOMTUIENDED SOLUTION Campus Repurposing Phase 2 includes three major projects: 1. North Center Re-Route 2. Construct New Fleet Building 3. Gonstruct Parking Garage These three projects are connected and largely dependent on each other because of location, timing and the overall campus design. The projects will ultimately allow us to:. Expand and consolidate the campus footprint while establishing a formal boundary between the Avista campus and the Riverview campus.o Modernize the aged Fleet Building and address Fleet queuing needs.. Expand and locate campus parking to align the available number of parking spaces with the number of employees working onsite, improving employee and public safety by reducing parking sprawl..

Rosentrater, Avista Schedule 3, Page 130 of 186 o Phase 2oProiect 1: North Center Street Re-Route Avlsta-owned properties separated from campus by North Genter Street North Center Street currently divides us from the eight acres of property owned to the north on Ross Court. Re-routing North Center Street will allow us to consolidate our campus to include these properties. As North Center Street is a major city arterial that connects lndiana Street to Upriver Drive, a considerable amount of traffic uses the street daily. This traffic creates an ongoing safety risk to employees moving back and forth between the properties. lt also creates challenges with securing the lots during business hours (gates, entrances, etc.). Beginning in 2013, Avista began discussion with Riverview to plan the future development of each of our campuses. Riverview management expressed concern with future development on our adjacent properties due to the proximity of these properties to their resident housing. With no formal separation between our campuses, they were concerned with the height of proposed buildings as well as idling dieseltrucks next to their resident properties. Severaloptions were considered (see options listed below). After many discussions, there was interest on both sides to explore rerouting North Center Street to the north in order to: 1) consolidate our properties into our secured €mpus; and 2) give Riverview a formal separation between our campuses.

Vehicle and Building Size The originalfleet building was built to house smaller half-ton pick-ups and has been expanded twice through the years to accommodate the increased size of the new service trucks, once in 1978 and again in 1999. The size of vehicles in today's fleet have continue to increase since 1999 and some of the current fleet is difficult to service in the existing building. The curent building is much smaller than City of Spokane and Waste Management facilities, which utilize similar-sized vehicles. Many of our larger trucks cannot be worked on in the existing space without leaving the doors open. ' 't t,?{. ... I .t +q\ t--D 1,t: lttl'i;{'/t I I ,l: / I i I ./ I ,! f ( I xI'r -.-, qa,t I / q" .

The existing fleet building is not CNG rated and all CNG-fueled vehicles must be taken offsite for repairs. To make the building CNG compliant would require the addition of a new emergency exhaust system. The estimated cost to make the building CNG compliant is around $1.3 Million Environmental The hydraulic lift system installed in the existing building did not include secondary containment when originally installed, and testing has indicated possible leakage of hydraulic oil in the soi! under the building. Relocation of the building will allow us to completely encase all new hydraulic systems and mitigate any current or potential leakage. Safety The existing fleet staging and queuing area is also in the heart of the campus and is directly adjacent to multiple parking canopies and surface parking areas. This staging area is small and requires multiple trips in and out of the area for day-to-day operations. A main employee walkway also goes through this major traffic area and brings considerable safety risk to the company as some of the pedestrian traffic can be hidden by the parking canopies. Moving the fleet building to the north will allow for increased queuing area and lessen the employee and operations traffic risk considerably. Building Conditions ln addition to compliance, environmental and safety issues, the existing building has a number of conditions that affect operations and employee safety and health, including the issues below (see attachment Corp Fleet Building Issues for complete list). o Current facilities have bays less than 14'wide. Current trucks are 103" wide at the mirrors, leaving limited space for maneuvering and working on vehicles.o We cannot lift rear tandem axle trucks with in ground lifts. We utilize wheel lifts which add 38" to the width of the vehicle. This leaves less than 2' for the technician to move himself and his tools into position.

The number of parking spaces available for employees is approximately 728 (not including visitor and disabled paking). Assuming not all employees are on the property at any one time, a minimum of 400 additional parking spaces are required each day to address the current existing need as well as additional spaces for future flexibility. Avista leases parking space along Perry Street from Burlington Northern Railroad (BNR), in an open-ended lease that can be cancelled by BNR with 30 days written notice. Employees walk across railroad tracks to get to and from the buildings and these parking areas. Additionally, loss of this lease would result in the loss of almost 200 parking spaces. Aligning campus parking with employee count has been addressed through the years by relocating materials storage yards from the campus footprint and adding surface parking lots (see below). o O Mission Campus Parking Space Count 2008 538 Added Spaces South Mission Lot 2009 +57 Added Spaces Transformer Storage Lot 2009 +55 Expanded North Pole Yard 2012 +124 Added North Ross Court 2012 +49 Total Current Parking Spaces (includinq Disabilitv and Vlsitor ParkinE) 823 Total Parking Spaces Available (excludlnE Disability and Visitor Parkinq) 728 Estimated Employees/Contractors Assigned to Mission Campus as of June 2016. 1282 Estimated Employee/Contractors e not at Mission Campus on any one day (15o/o\ -129 Shortage of Parking Spaces to Meet Current Need for Employees/ Contractors Assigned to Mission Campus** 425"" Year Parking Spaces Business Case Justification Narrative a Exhibit No. tsage 13 of 20 Case No. AVU-E-19-04 H. Rosentrater, Avista Schedule 3, Page 140 of 186 Action Taken o o o Phase 2 Using valuable campus real estate for parking lots has required us to take our operations vehicles and materials storage offsite to our Beacon substation property more than a mile away, increasing crew time and resources to access materials and vehicles each day. This daily deficit in parking is currently absorbed in gravel lots on Ross Court and along the railroad tracks on Burlington Northern Railroad land. This parking is not in compliance with City of Spokane parking code, and we could be required to cease at any time. Additional parking overflow beyond these locations usually takes place in the immediate neighborhoods around Avista, and has resulted in frustrated calls, threats, and visits from our residential neighbors. The proposed parking garage is intended as a long-term solution to the employee and visitor parking deficiency and related safety concerns.

Operations traffic peaks in the mornings and afternoons, when employees are often walking to or from their vehicles. Parking areas are open and must be maintained throughout year to keep lots safe and clear of seasonal conditions. Even with ongoing maintenance, lost work days due to slipping and falls on the main campus (both inside and outside) is estimated at 1 1,000 days since 1997. ln the first quarter of 2017 , Avista experienced a record number of slips, trips and falls related to icy conditions.

Avista will Iose the sublease on the hangar after July 31, 2018, at which time Merlin's Iease will end. At that time, airport management plans to demolish the existing hangar as part of a plan to reclaim the existing property and relocate private hangars to a different part of the airport. At that time, Avista will need to secure a new hangar for the aircraft. o o Business Case Justification Narrative o Exhibit No. g Page 1 of 6 Case No. AVU-E-19-04 H. Rosentrater, Avista Schedule 3, Page 148 of 186 Airport Hangar o o 3 PROPOSAL AND RECOMMENDED SOLUTION. Four options were considered for securing a hangar for the aircraft, including building a new hangar, extending use of the current hangar, relocating to another airport, and co-use of an existing hangar. Option 1 (Recommended): Build a new Avista-owned hangar on land leased directly from Spokane lnternational Airport. This solution is recommended for the following reasons: o Spokane lnternationalAirport is convenient to headquarters. o The airport is currentty offering a good selection of plots, with good approaches and footprints that would allow easier separation of the public entrance from the secured part of the airport. . We could secure a long-term lease with the airport and lock in lease payments. Current discussions include a lease term of up to 50 years. . Construction in 2018 would allow us to take advantage of lower interest rates and construction costs than what we would likely get in 2019 or 2020. r Leasing directly from the airport will allow us to de-ice and fuel the aircraft ourselves or through a contractor we select, rather than having to use the airport's services exclusively, saving costs and increasing efficiency. o Constructing the hangar would allow us to design a structure with the future in mind. The current aircraft has an expected life of up to 20 years, and a new aircraft would change the required size of height and width of the hangar. A new hangar would include the following elements (see schematics): o Ample plane storage and room for maintenance and maneuveringo Minimal parts storageo Restroomso Offices for flight staffo Secure parking with Avista accesso Separate unsecured and secured areas for travelers Optlon Capltal Cost Start Gomplete Rlsk Mitlgation 1.

Rosentrater, Avista Schedule 3, Page I 50 of I 86 rt I L P Airpoft Hangaro o t, ? Option 2 - Direct lease from Spokane airport We looked into pursuing an extension of the existing sublease, and confirmed that we can convert our sublease into a direct lease with the airport and stay in the existing hangar temporarily. However, because of airport management's plans for vacating the land the current hangar is on, we would be able to do this for a maximum ol6-12 months, and we would need to be in negotiations with the airport on a long term solution. Option 3 - Share existing hangar There is cunently one hangar at the Spokane lnternationalAirport large enough and with owners who would consider co-leasing with Avista. Avista would not have ownership of this building, which presents several challenges: o Sharing space with co-lessor(s) would require additional security measures to protect our aircraft and ensure the security of our network (located in the office of the flight crew). These measures could require additional construction of secured entrances and areas and/or hiring security personnel, and would need to be coordinated with and approved of by any co-lessors, at Avista's cost. r There is also a concern about damage to the airplane. The plane would be stored in tight quarters alongside another aircraft, and damage is more likely to occur as planes are maneuvered in and out of the hangar. 6 E Iil.IiitI{8 h4:e ,85 : -M.2 I\.-i\i --") a '--r H__l--- i q -'Or I I r I( 9. /o/ _[I /@/ E \@ -TYl o Business Case Justification Narrative txnlDlt l\o. 6 D, Case No. AVU-E- l9-04 vage 4 of 6 H.

E: g Airport Hangar Maintaining the aircraft and keeping it secure from co-lessor's employees and/or mechanics would present a security logistical challenges as well. o Currently we do not have to coordinate departures or arrivals with another entity. Co-leasing would require us to share flight information and coordinate our departures and arrivals with our co-lessor. o Additional future co-occupants could be brought in and affect Avista's use of the hangar. Option 4 - Store at another airpoft A. Felts Field was looked into as an option to move the plane but the runway is not long enough. A 7,000-ft runway minimum is required to safely land and takeoff with our current aircraft. B. The Coeur d'Alene airport was researched as a solution. There are no options to lease an existing hangar available; however there is the possibility of building a hangar at that location. The cost of building a hangar at the Coeur d'Alene Airport would be the same or comparable as building a hangar at the Spokane lnternationalAirport, but would increase overalltravel time and cost for employees having to drive to Coeur d'Alene for flights. o o Business Case Justification Narrative o Exhibit No. 3 Page 5 of 6 Case No. AVU-E-19-04 H.

Eric Bowles (Corporate Facilities Manager.) and Rod Staton (Facilities Project Manager) traveled to the two sites and stayed in the rooms to evaluate the overallcondition of the facilities and to experience the conditions first hand. lnterviews were conducted with employees that were staying in the rooms to receive feedback. Photographs were taken of the facilities and a list of possibilities was put together to discuss with sponsors and stakeholders. (See Appendix). During these inspections, extensive issues were found, including structural and water damage to the siding and framing due to faulty construction and subsequent water penetration, inadequate and antiquated electric heating systems, HVAC deficiencies, non-cornpliant electric breaker panels and inadequate insulation. Subsequent inspections exposed black mold and mildew caused by water penetration in parts of both facilities. Upon sharing the facilities assessment with the sponsors and stakeholders it was decided that the next logical step would be to create a project to address the problems discovered at the living facilities. Bernardo Wills Architects of Spokane was hired to recommend the level of modernization needed to address the concerns found during the site assessment, and create the scope of work needed to renovate the facility. (See Appendix for concerns raised during the site assessment.) 4 PROPOSAL AND REGOMMENDED SOLUTION Ootion 1 (Recommendedl - Remodel & correct issues at both facilities. The selected altemative includes the significant renovation of the living facilities at Clark Fork and Noxon to address the identified problems and components to extend the life of the facilities and update the facility to a more modern and energy efficient state. This alternative combines the required repair work with the facility renovation to avoid duplicating efforts and saving costs on contractor mobilization and re-work. The completed facilities would provide years of additional service, increase the efficiency of energy usage, reduce annual O&M costs to maintain the structures, and provide a suitable environment for housing our workforce at these remote sites. With a centralized workforce based out of Spokane, it is criticalto provide lodging Business Case Justification Narrative Exhibit No. 8Page 2 of 8 Case No. AVU-E-19-04 H.

These living facilities are utilized by Avista maintenance crews and engineering personnel when performing work at Noxon Rapids Dam, Cabinet Gorge Dam, or other Avista equipment in the region. Both Noxon Rapids Dam and Cabinet Gorge Dam are in very rural and isolated areas. Options for lodging are extremely limited, with Sandpoint or Thompson Falls being the nearest towns. Travel time from these towns would limit the efficient use of crews for work at these facilities. Without the continued availability of the living facilities, it's estimated that it would cost $316,200 annually to procure lodging at alternate sites for work at the plants. Over a Z}-year period, the annual cost to procure alternative lodging would exceed the total cost of the project by more than double. The scope of the remodel project includes each of the 16 individualguest rooms, bathrooms, kitchen, dining room, activity room, lobby, laundry room, office, basement and building exterior. This work would extend the life of these facilities and update them to a more modern and efficient state. lnterior scope work includes: full bathroom remodels, HVAC replacements/installs, window trim replacements, lighting upg rades, new fl oori ng/trim/paint, new cab inets, countertops, & furniture, replacement of hot water heaters, new door handles & locks, and more. The exterior scope of work includes repair of termite/rot damage, re-siding, new paint, installation of snow guards & gutters, replacement of exhaust fans/vents, and more. During each construction period, the facility being worked on will be unavailable for use until the first wing of eight rooms and the common areas are completed. Once constructions moves to the second wing of eight rooms, the facility will become available at half capacity. Crews working in the region will be required to utilize the other living facility until capacity is reached and make other arrangements after that point. Option 2 - Addrcss issu* with multiple oroiects over 5 vears. This option spreads the cost of correction over a S-year period. The mold and mildew issues would be addressed first and the additional items would be addressed systemically over time. The major argument against this approach is the down time in room availability while the work is occurring. Each discovered issue needs time to be addressed in both facilities, requiring prolonged periods of time where the rooms would unavailable to the crews. This option would drive up hotel room oosts to accommodate work at the living facilities. The other major issue with this option is the staging of the work. Many of the discovered issues require substantialdemolition to complete the work. There is a cascading effect and a logical order to trade stacking, creating logical work flow, this option does not afford the stacking of trades to create efficiency. OptionS-DoNothins. Disregarding the water penetration is not an option as this would render portions ol and eventually the entire facility, uninhabitable over time. The lack of available living facilities would inhibit plant maintenance and upgrade work resulting in increased project costs and customer rates. This option is unacceptable due to health issues associated with mold and mildew. Business Case Justification Nanative Page 3 of 8Exhibit No. 8 Case No. AVU-E-19-04 H.

The JATC will, as outlined in the Avista Standards of Apprenticeship, secure the instructional aides and equipment it deems necessary to provide quality instruction. To the extent possible, related instruction will be closely correlated with the practical experience and training received on the job. 2 BUSINESS PROBLEM The capital allowance allotted to the Training Department through the Apprentice Training Business Case provides for tools, materials and equipment for training apprentices and journey workers across eleven skilled crafts or trades. This training consists of hands-on skills development that builds competency in a safe learning environment that may not always be available or controllable in the field. A well trained and competent workforce ensures reliable delivery of energy to Avista's customers and maintains a safe environment for employees, customers and the general public in all of Avista Utilities service territories. ln addition to creating a safe and skilled workforce, this training helps Avista to deliver timely training on new and emerging technologies as well as meet several federal and state mandated regulations including:. Department of Labor, Standards of Apprenticeship - Title 29 CFR 29.5 (bX4) and (bXg) - Apprentice on the job training and related instruction. Department of Labor, Occupational Safety and Health Standards - Title 29 CFR 1910,269 (aX2) Electric Power Generation, Transmission, and Distribution training. Department of Transportation, Transportation of Natural Gas and Gas by Pipeline: Minimum Federal Safety Standards - Title 49 CFR 192.805 (h) - Qualification of Pipeline Personnel, Qualification Program training. State of Washington - WAC 480-93-013 (4) - Covered Tasks: Equipment and facilities used by pipeline company for training and qualification of employees o a Business Case Justilicalion Narrative o Exhibit No. 8 page 1 of 3 Case No. AVU-E-19-04 H. Rosentrater, Avista Schedule 3, Page I 62 of I 86 Ap p renti ce/C raft T rai n i ng o o 3 PROPOSAL AND RECOMMENDED SOLUTION Capital expenditures under this program could include items such as building new facilities or expanding existing facilities, purchase of equipment needed, or build out of realistic utility field infrastructure used to train employees. Examples include: new or expanded shops, truck canopy, classrooms, backhoes and other equipment, build out of "Safe City'- commercial and residential building replicas, and distribution, transmission, smart grid, metering, gas and substation infrastructure. Without the ability to provide specific hands-on operational training in-house, the company takes on several risks which include the inability to successfully fill critical craft positions with the necessary knowledge, skills and abilities specific to Avista's operations. This would have a direct and significant negative impact on system reliability, customer response times, as well as employee and public safety. Regulating bodies may also de-certify our apprentice program due to not meeting mandatory requirements for adequate training. As a result, the inability to train in- house would require extensive travel to fulfil! our training obligations. The cost to outsource hands-on-training and field simulations would be approximately $473,000 a year for facility rental alone. This is based on current training programs that have averaged over 530 hours per year at the training center. The overall annual costs including travel, lodging, meals and registration are estimated to more than triple this rental cost and be classified as operations and maintenance costs. Again this would result in a negative impact to Avista's customers.

The model uses benchmark data, purchase and auction data, combined with nationwide vehicle information that Utilimarc uses to build an accurate and robust model. The Fleet Specialist for Capita! then takes the results of the model to validate, verify usage and work with operations managers to ensure that the identified unit meet their business needs. Capital projects requests are created for each discrete project (vehicle/equipment) that is approved by the Fleet Manager with notifications to the Manager of Shared Services and the Vice President of Operations. 2 BUSINESS PROBLEM FIeet equipment as it ages experiences a growth in cost related to its operation. Those costs are driven by the requirement of more parts and more labor required to keep that unit up and running. As your fleet's average age increases you will see a steady but accelerating trajectory of costs servicing hours required. lt can be described as more complex repairs requiring more hours and parts to fix. Those increasing costs are not just the burden of Fleet; the users will see the impact in lost productivity/downtime. ln a2011 analysis of Avista's class 46 vehicles and a subsequent analysis done in 2016 saw a 52o/o reduction in the labor hours required per truck by bringing the classes average age from 9.5 years to the industry average of 5.5 years. 2010 201 1 2012 2013 2014 201 5 AVA Avg Age 8.03 7.81 7.59 6.81 6.55 6.23 lndustry Avg Age 6.11 6.27 6.27 6.56 6.53 6.38 Avg Op Cost / Unit $10,924 $11 ,558 $11,534 $10,845 $9,739 $9,285 a Business Case Justification Narrative Exhibit No. 8 Page 1 ot 14 Case No. AVU-E-19-04 H.

Our life cycle model seeks the goal of balancing risk and limited investment dollars. The model allows Fleet to provide users with a reliable and safe tool that is ready for work at any given moment. The fully funded option allows our capital purchasing model of equipment to continue replacing aging equipment in a predictive manner that keeps technician staffing levels constant to the predictive number of repair work orders generated. The program does not include additions to the existing fleet. The analysis of the data by Utilimarc shows that this fully funded model over time will yield the lowest cost per vehicle. The recent large outages from the summer ot2014 and November 2015 show the strength of our fleet. During those thousands of hours of combined operation we only had two minor breakdowns that we were able to quickly repair and return to service before the start of the operator's next shift. The customer benefits from this in two distinct ways. One, that crews are quicker to respond to issues because they operate reliable equipment that can be ready for duty. Two, that costs for customers remain steady from a fleet cost perspective because we have a constant investment in the equipment along with a progressive maintenance that has a monthly average over 95% of vehicles ready for duty. By pursing the recommended investment path we avoid rising maintenance costs, outside of economic inflationary trends, and increasing down time due to mounting demand repair work orders. Additionally, this investments allows us to purchase equipment that has modern emissions controls or alternative energy sources allowing us reduce carbon emissions from our fleet vehicles. Option 2- Partiallv Fund Reolacement Proaram The partially funded, option 2 continues to replace vehicles but at reduced amount when compared to the recommended option. The combined ownership and maintenance costs to appear to be nominally less in costs over the time of the model. However what you see is a rapidly aging fleet in the last two thirds of the modelwhich have increasing work order counts for repairs and significant impacts to reliability/uptime not shown in the totalfleet costs. o o o Fleet Seryices Capital Plan Business Case Justification Narrative Exhibit No. haoe 2 ot j4 Case No. AVU-E-19-04 H. Rosentrater, Avista Schedule 3, Page 1 66 of 1 86 o o o Fleet Seryrces Plan Ootion 3 - Do Not Fund Replacement Prooram Option 3 is a plan designed to replace a unit only at failure. This model has rapidly increasing costs due to significant repairs required. This model will require increasing numbers of repair work orders to be assigned to outside vendors since company technicians will be able to handle only incrementally more work than today. This outside work has a higher price per hour and higher parts costs due to vendor markups. This model will lead to increasing down time of equipment as it ages. The repairs will become more costly and consume more technician time. lncreasingly, even with the best preventative maintenance plan, there will be unplanned failures in the field downing a crew while the issue is addressed. This model was practiced at Avista for over 20 years and led to clusters of vehicles failing at approximately the same time and creating capital constraint issues. Vehi c I e Rep lac ement An alvs is The following information demonstrates the effect of three different replacement strategies on Avista's Fleet performance. Three projections were built using Utilimarc Vehicle Replacement Model (VRM) to show the effect of different levels of capital commitment on fleet maintenance cost, ownership cost, average age, and demand repairs. ln the Full Budget (Option 1) scenario, vehicles are replaced in line with each vehicle's calculated, optimal, lifecycles with an annual capital cost starting at approximately $8,000,000, The Half Budget (Option 2) scenario cuts the annual replacement budget in half to start at approximately $3,700,000. The No Budget (Option 3) scenario restricts the annual capital cost to $0. Summary The table below shows the effects of each budget on annual vehicle ownership and maintenance cost for Avista's fleet. The full projections are provided on the pages to follow. Annual Vehicle Ownership and Maintenance Cost 2016 Full Budget $9,588,817 Half Budget $9,439,904 No Budget $9,350,935 2020 $9,735,956 $9,274,112 $9,145,384 2025 $10,604,849 $1 0,1 97,1 51 $10,854,088 2030 $1 1,700,794 $1 1,658,431 $13,913,603 Avista's fleet is currently ahead of its ideal lifecycle. This is shown by the increase in average age we see under even the Full Budget scenario. Because of this, the No Budget scenario is marginally cheaper in the first few years of the projection (<2'/o). However, by the 1Sth year, the No Budget scenario is 19% higher than the two alternative scenarios. Avista would also see average age increase from 9.0 years to over 20 years under this worst-case scenario. The Full Budget scenario is marginally more expensive then the Half Budget scenario in these projections, but will begin to outperform the Half Budget scenario beyond the 1Sth year. While their total costs are comparable, the Full and Half Budget scenarios differ in how money is being spent. Under the Full Budget scenario, capita! investment is larger each year, but maintenance costs are significantly lower. The Full Budget scenario also offers younger units for the crews to operate (average age of 9.22in the 15th year) vs Business Case Justification Narrative Exhibit No. 8 Page 3 of 14 Case No. AVU-E-19-04 H. Rosentrater, Avista Schedule 3, Page I 67 of I 86 14.74 in 1Sth year) and fewer demand repairs (7 ,082 work order in the 15th year). Conversely, The Half Budget scenario sees a smaller capital investment each year, but the unit for the crews to operate will be older (average age of 14.74 in year 15) and will see more demand repair (9,671 work orders in the 1Sth year). Vehicle condition, availability and downtime should also be considered in these scenarios. ln order to maximize safety, reliability and responsiveness for customer needs, including emergency outage restoration, vehicles should be equitable in terms of standards and in optimalworking condition. Assumptions o o a o lnflation: All capital, ownership and maintenance costs are increase annually be 2o/olo account for inflation. Consistent Replacement: The replacement model is programed to replace a consistent number of unit each year to achieve more predictable capital requirements and avoid replacement bubbles. When many vehicles are concentrated in relatively few vintages, these "bubbles" can cause sudden increases in parts and labor cost, vehicle downtime, and technician requirements. Replacing a constant number of unit each year avoids this problem, but consequently the model will occasionally replace a unit before it reaches in lifecycle or let a unit run beyond its lifecycle. Maintenance: Maintenance cost includes the cost of al! parts and labor needed to maintain the asset over the course of its lifetime. Note that maintenance cost does not include the cost of fuel or any administrative or corporate overheads. While there will be some fuel efficiencies associated with running younger vehicles, the unpredictable nature of the price fuel make it difficult to quantify the savings associated with these efficiencies. Maintenance Savings: The replacement model maintains a constant cost per wrench-turning hour of technician labor. This means that when maintenance cost increase or decrease, the model adjusts staffing levels to meet the increased or decreased demand for labor.

Rosentrater, Avista Schedule3, Page l7l ofl86 Methodology Annualized Total Cost For each class, Utilimarc's Vehicle Replacement Module (VRM) determines what lifecycle achieves the lowest cost to own and maintain an average asset over its lifetime. This done by calculating the annualized total cost for each potential lifecycle. Annualized cost total is the sum of all ownership and maintenance cost a unit obtains over the course of its !ife, divided by the number of years the unit is in service. Minimizing annualized total cost guarantees the lowest total cost over the life of the asset. As an example, the table below shows the annualized cost for the possible lifecycles of a light duty pickup truck. Replacement Age Annualized Total Cost Deviation $5,964 $5,759 $5,598 $5,476 $5,390 337 1 2 3 4 5 6 3.10/o 1.50/o 1.60/o 3.00/o o o 8 I 10 11 12 13 14 $5,316 $5,345 $5,397 $5,472 $5,567 $5,682 $5,816 Consider the following three replacement scenarios over a 14-year financial period: Scenario 1: A fleet manager plans to replace this vehicle every year. The annualized cost of this replacement strategy is $7,811. Over the 14-year period, this replacement strategy will cost fleet 14 x $5,946 = $83,244. Scenario 2: A fleet manager plans to replace this vehicle every seven years. The annualized cost of this replacement strategy is $5,810. Over the 14-year period, this replacement strategy will cost fleet 14 x $5,31t = $74,382. Scenario 3: A fleet manager plans to replace this vehicle every fourteen years. The annualized cost of this replacement strategy is $6,913.

Utilimarc recommends replacing units within 1.0o/o of the true lowest cost of ownership. This generally provides a three-year range for replacement, which allows for flexibility when planning replacement without dramatically affecting overall cost. o o Business Case Justification Narrative Exhibit No. 8 Page 9 of 14 Case No. AVU-E-19-04 H. Rosentrater, Avista Schedule 3, Page I 73 of I 86 Fleet Serurces Capital Plan Modelinq Ownershio Cost The Vehicle Replacement Model uses an exponential decay modelto project the ownership cost of an asset over its lifetime. Each asset is assumed to lose 18% of its current book value every year as a cost of depreciation. This decay rate of 18% is established based on historical auction information from companies across the industry. Annualized Ownerchip Cost is calculated by taking the cumulative sum of each year of depreciation for the asset and dividing by the number of years the asset is in service.

Sharing the investment in DERs across multiple building owners and coordinated across the grid reduces the investment cost to each building owner as well as provides opportunity to optimize utilization - economies of scale or "horizontal values". Leveraging both economies of scope and scale to derive value out of DERs requires the development of a platform to supervise, control, synchronize and optimize these assets -Avista Distribution System Platform (ADSP). Micro-Transactive Grid (MTG) is an extension of the ADSP platform to support the optimal utilization of DERs. Rather than optimizing a single building's utilization of DERs, the IVITG will leverage building fleets, load diversity, and building management systems to optimize the DERs across the distribution loop network. ln addition, the MTG will be designed to sectionalize the load into distinct districts which share common DER assets to improve system resiliency and reduce DER investment requirements. The opportunity to address these issues is a Strategic opportunity which has a great deal of support from the Washington State Department of Commerce, the Governor of the State of Washington, and Avista's Clean Energy Fund 2 Partners (l\4cKinstry, ltron, SEL, SPIRAE). By enabling the seamless integration of renewable and distributed energy resources, and by leveraging and extending the electric distribution grid infrastructure to support intrastate micro-transactive energy markets, Avista can enhance the role and relevancy of utilities in ways that directly align with the state's objectives for reducing emissions and increasing the strength and competiveness of its economy. New types of energy and energy service models can create opportunities for utilities to act as trusted brokers between providers and Clean Energy Fund 2 - Shared Energy Economy consumers - to manage and optimized use, performance, safety, and reliability towards a more responsible, resilient, and sustainable energy future. A delay in implementing this project could result in a lost opportunity to address these issues and the loss of matching funding from the Department of Commerce. Avista's analytical partner, the Pacific Northwest National Lab (PNNL), will extend the analysis leading to a valuation of the Shared Energy Economy by simulating a transactive market. ln these simulations, a "trading hub" enabling energy transactions between participants will be designed across multiple MTG platforms. Due to the limitation of regulatory requirements, the energy transactions will be simulated rather than executed across the MTG platforms. However, once established, the MTG platforms will operationally be utilized to facilitate the exchange in energy and balance the grid logistics from system capacity, available resources, trading routes, and system stability. The valuation and operation of the MTG Platforms will determine technical, operational, and economic opportunities to deploy DERs across an investment community participating in a Shared Energy Economy. 3 PROPOSAL AND RECOMMENDED SOLUTION Option Capital Cost Start Complete Do nothing $0 lmplementation of CEF2 Proposal $8,000,0001 0s12018 612020 Proiect Prooosal/Solution Overview Avista and its Partners will control and optimize the utilization of shared DERs across a MTG. The IiITG will consist of building management systems, solar panels, and energy storage assets integrated on a loop feed to support a shared model of renewable energy resources for commercial, university campus, and industrial parks. The ttITG project will be deployed in Spokane's University District in order to maximize the impact and visibility of the project. The University District, designated by the Department of Commerce as an lnnovation Partnership Zone, is adjacent to Spokane's downtown core. It consists of 770 acres, including the campuses of Gonzaga University, Washington State University Health Sciences Spokane, and programs from Eastern Washington University, Whitworth, University of Washington and Spokane Community Colleges. ln addition to higher education, the University District is home to Urbanova, a collaborative effort to create a living laboratory for smart cities of the future. Avista and its Partners will extend the valuation of DERs into a Shared Energy Economy model. ln this model, Avista will be evaluating how a conventional micro-grid and the inherent combination of distributed assets could provide value while connected to the grid or during an islanded condition away from the distribution system. ln a Shared Energy Economy, building owners and tenants can share in the investment and benefits obtained by a MTG. The valuation analysis for a Shared Energy Economy is fundamentally trying to show that a non-utility portion of the community can participate in the deployment of local DERs and derive both financial and operational benefits which cannot be realized within the conventional regulatory and utility model. ln addition, the Shared Energy Economy can help support the valuation of DERs when compared to traditional centralized generational assets. I Of the $8 million tolal capital cost, $3.5 nrillion has been appropriated and approved by the Washington State Departlnent of Comrnerce and will be provided to Avista upon nreeting defined Milestones Page 2 of 5 Exhibit No. 8 Case No. AVU-E-19-04 H. Rosentrater, Avista Schedule 3, Page I 80 of I 86 o o Business Case Justification Narrative o o Clean Energy Fund 2 - Shared Energy Economy To provide analysis to demonstrate the above statements, Avista and its partners will develop a set of operational modes for the MTG including both grid connected and grid islanded states. Two ttITG "platforms", or "nodes", will be deployed. The MTG platforms consist of DER assets, control devices, and distribution equipment necessary to integrate, control, and operate the MTG Platform. The projected list of major equipment for the project is listed below: . 100 kW350 kWh Energy Storage Asset . 500 kW/1.5 kWh Energy Storage Asset . Solar Arrays with total peak capacity between 50 and 125 kW o Avista intends to utilize 4-quadrant smart inverters compliant with UL1741A and similar to those compliant to CPUC Rule 21, allowing for extended voltage ride through as well as voltage and frequency grid support . 2750 kVA Power Transformers .

Final Report - Decembes 2019 Strateqic lnnovation The innovation of the project's business case lies in the development of a shared economy to reduce the initial cost of the DER assets and to increase the value from the DER assets and their operation. The MTG distributes the cost of distributed generation assets iike solar and storage across multiple building or tenant members to reduce the cost of renewable assets per member. This economic model is similar to the Combined Heat and Power (CHP) model which shares the waste heat across multiple buildings by the use of steam pipes. The MTG will supervise and control the renewable assets to coordinate and optimize their utilization across Avista's distribution loop feed between building and assets. The functionality above is not being met by other vendors or utilities in the industry, thus allowing a significant opportunity for innovation in an open part of the market.

This allowed the Grant Application to include a budget and request developed with a fair amount of confidence, and provided a stepping stone for the Phase 0 process. Phase 0, facilitated by Avista and supported by the Partners, was an opportunity to refine the proposed scope and budget of the Project. During a multi month period, Avista and the Partners met numerous times to better understand the scope of each Partner's role and to produce a 30o/o design document with a more accurate cost estimates. Given the unknown issues that can arise during the deployment of new technology and the experience of Avista and others during the CEFI implementation, the Department of Commerce was highly supportive of this effort and provided funding during the development process to fund this effort.

The secondary source will be fed from 3rd and Hatch feeder to the development at an approximate cost of $281,630 dollars. Currently, the development is under construction and a short window of a week exists to trench the underground supply to the development. The south landing development consists of the Catalyst and HUB buildings located in the Spokane UDistrict on the South side of the tracks. As a part of the development, the HUB wil! host a central HVAC system, electrical switchgear and distributed energy resources which will be operated by a private central plant operator. Due to the unique characteristics of the development's central plant, Avista Utilltles recognizes it will provide a platform to experiment with both cost and value rate design. So, in conjunction with the development, Avista has proposed to Department of Commerce Clean Energy Fund lll to leverage the central plant (Eco- District) assets to support operationa! scenarios which balance the energy and capacity needs of the plant against the appropriate utilization of the grid. The CEFlll proposal includes the cost of the secondary source and Automated Transfer Switch (ATS) but it may take a couple months before we are notified by the Department of Commerce whether we have been awarded the grant. Due to the construction schedule, the secondary source and ATS switch need to be installed in the next week while the site trenching is available. ln light of this constraint, we are proposing to fund the secondary source through this request. lf awarded the grant from the department of Commerce, the cost would be shifted from this account to the new Capital Project Request developed as an outcome from CEFlll project. o ExhibitNo. t Page 1 of 3 Case No. AVU-E-19-04 H.

Under the build phase the central plant will serve building tenants with hot and chilled water which will be offset by aggregating distributed energy resources residing in the development. The developer's goal is to obtain a net-zero, carbon free development. During the pilot phase, the central plant will also be designed and operated to supply the eco-district developments plug and fan load through its 480 V system. Due to the unique characteristics of the development's central plant, Avista recognizes it will provide a platform to experiment with both cost- and value-based rated design. Also, the central plant's point of interconnection with Avista's distribution system provides operationalflexibility from transmission and distribution deferral to load shifting for seasonal demands. Much of the operational flexibility is enhanced by the supply from two 3'd and Hatch feeders since one of the feeders is summer peaking and the other is winter peaking.
