Approved Business Case Spend Amount 2016‐2017 ($000s ‐ System): $7,9301
Transfer to Plant Amounts ($000s ‐ System):
Business Case Description:
The Kettle Falls generator is 32 years old and is at the end of its expected life. The stator can be rewound
on its scheduled basis during the spring outage of 2016 instead of running it until it fails. This project
consists of monitoring the existing machine, developing rewind contract, manufacturing replacement
coils, disassembly, coil removal, new coil installation, reassembly, startup, testing and commissioning. The
consequences of a stator failure include an unscheduled outage with lost generation, loss of renewable
energy credits, long term interruption of fuel supply, collateral damage to the core and hydrogen cooling
with resulting safety hazards.

Business Case Description:
This project is to replace the unit and station service control equipment with a system compatible with
our current standards. The Bailey Net 90 equipment that is installed currently is obsolete in that
replacement of the system can only be done through secondary and salvage markets. In addition, the
current system does not provide enough inputs and outputs that allow us to implement our standard unit
control and monitoring schemes. This work will replace the existing panel and control systems with a new
system. The scope of work has been expanded to include replacement governors, voltage regulators, and
protective relays.

Approved Business Case Spend Amount 2016‐2017 ($000s ‐ System): $01
Transfer to Plant Amounts ($000s ‐ System):
Business Case Description:
This is the Capital portion of a major overhaul project planned for Cabinet Gorge Unit 1. The runner hub
has significant issues, and will need to be upgraded to allow for frequent cycling with integration of
intermittent resources. The present AVR is relatively slow response due to its hybrid design. It also has
no limiters for generator protection. A new system will improve both of these. The machine monitoring
is to allow for better analysis of machine condition for this critical unit. New protective relays are to be
installed and new controls will be integrated with the project to replace the failing Bailey NET90 system.
Rehab of this unit will also allow flexibility around minimum flow for fish habitat.

Business Case Description:
Avista had planned to maintain the south channel gates to comply with FERC Dam Safety directives. When
a pre‐construction underwater investigation was done, it was discovered that the condition of the
concrete structure was very poor and would not handle the planned work. This has resulted in an effort
to evaluate options. This item includes an engineering investigation into options and project estimates.
It is anticipated that much of the existing concrete structure will be removed and replaced with a new
concrete structure, new gates and hoist systems to automate the operation.

Approved Business Case Spend Amount 2016‐2017 ($000s ‐ System): $3,5001
Transfer to Plant Amounts ($000s ‐ System):
Business Case Description:
The gantry crane at Cabinet Gorge is original equipment and is now more than 70 years old. This is a
critical asset needed to function without problems in order to service the powerhouse. We have
experienced problems with this unit, as recently as last year during the Cabinet Gorge Unit 1 project. The
controls are antiquated and have had problems. The integrity of the condition of the crane, the state of
the controls, and the inability to directly pick the Unit 1 rotor, the GSU's and to manage the tailgates make
replacing the crane with a modern and fully functioning crane a needed item.

generating stations. This program is specifically for Coyote Springs 2, Colstrip, Kettle Falls, and
Lancaster. Work includes replacement of items identified through asset management decisions
and programs necessary to maintain reliable and low operating costs of these plants. As this
program proceeds, it is expected that forced outage rates and forced derates of these facilities
will decrease to a level one standard deviation less than the current average resulting in more
economic benefits for the project.

Business Case Description:
Construct a new warehouse in 2012 and remodel the old warehouse in the Service Building to
accommodate 110 work stations in 2013. Also add 125 parking spaces. New warehouse shall utilize
current material handling technologies to increase employee efficiencies, and its height will allow for
more material to be stored per SF, thus using our limited SF here at the COF more efficiently. Provide
IS/IT infrastructure and networking in north half of the COF where it is currently non‐existent, in
anticipation of future projects. This project will also allow the HVAC renovation of the north building wing
to be accomplished in one year rather than a staged process.
O&M Offsets are gained due to line trucks and employees not having to travel and off‐load waste maters
that are recyclable or hazardous. Offsets are anticipated to be approximately $43,000 in 2016 and
$60,000 in 2017 for a total of $103,000 on a system level. Washington’s allocated portion of these offsets
are $81,000 Electric and $22,000 Natural Gas.

Building, convert all of 1950's Service building to Office Space, and increase parking lot size and build 2‐
story parking structure. Our parking lots will be beyond max capacity. The Fleet Garage is over 50 years
old and is constrained by its dims from our ever enlarging vehicles and line trucks. New garage will allow
for maintenance of CNG vehicles, current building does not allow this. Once Fleet is moved, a distinct
separation b/n Operations / Service vehicles and Administrative Employees and vehicles. Separation will
increase safety by eliminating intermingling of pedestrians in work areas. Office building & parking garage
is projected to allow Call Center and any leased facilities to come back to Mission campus. Increasing the
COF lot size will allow for efficient space and multiple uses on campus.

EDIT, and OMT/ADMS applications. The selection of the COTS solution will occur after business
requirements are gathered and an RFI/RFP process is completed. The O&M estimates are related to the
RFI/RFP process, licensing maintenance fees and when parts of the system go live during the course of
the project.

To: Meter Data Management Capital Investment - 2016 GRC File
From: Heather Rosentrater, Vice President, Energy Delivery
Date: 5/13/2016
Re: Meter Data Management Capital Investment Considerations
Avista currently uses custom functionality through Oracle’s Customer Care and Billing (CC&B)
system to perform MDM-like functions instead of a dedicated Meter Data Management (MDM)
system. CC&B is not designed to support this functionality with large volumes of meter data, and
this functionality was intended as a stop-gap measure until an MDM system could be implemented.
Avista’s Meter Data Management (MDM) project is anticipated to provide the following benefits:
Improved estimation routines – under the current state, estimation relies upon historical data for
a given meter from the previous month or the equivalent period in the prior year. The MDM system
will allow consideration of daily reads that have occurred since the last scheduled read date, which
is a significant improvement over monthly reads
Service Order Management – the MDM implementation and its Service Order Management
(SOM) module will enable appointment scheduling and optimized routing. This will also allow
service order management to be centralized on one system, providing consistent work processes
(resulting in improved efficiency) for Avista employees and operations. The availability of the
integrated appointment scheduling eliminates the need for separate capital investment to enable
this capability.
Future benefits – beyond the current benefits offered by a dedicated MDM system, the MDM
system will provide a platform for the future implementation of advanced metering infrastructure
(AMI), which carries a multitude of separate benefits. The implementation of an MDM system to
support all of Avista’s services and jurisdictions concurrently is the most efficient alternative, and
therefore lowest overall cost method of implementing this system.
Rate Design Options – the MDM implementation will support the collection of data from meters
in all of Avista’s jurisdictions, including the existing advanced meters (AMR) deployed in Idaho
and Oregon. Collecting usage data may allow for additional rate design options in the future, such
as time of use rates and the institution of demand charges for smaller-usage customers.

Approved Business Case Spend Amount 2016‐2017 ($000s ‐ System): $6001
Transfer to Plant Amounts ($000s ‐ System):
Business Case Description:
Meter Minor Blanket is used for replacement of failed, damaged or improper meters at service locations
where a meter has previously been installed. There are several events that could lead to a meter needing
replacement including: meter check orders where the meter is found to be damaged or stopped, meter
tests where the meter is found to be out of accuracy tolerance, or inspection orders where the service is
altered requiring a different meter type. Meters are replaced in order to ensure that each customer is
properly billed for their electric usage, which means maintaining properly working meters at each service
point. The risk of not maintaining the meters is inaccurate billing, estimated bills, and re‐bill work by the
Customer Service department.

Business Case Description:
The existing Noxon Rapids 230 kV Switchyard requires reconstruction due to the present age and
condition of the equipment in the station. The existing bus is constructed as strain bus (which has suffered
a number of recent failures) and is configured as a single bus with a tie breaker separating the East and
West buses. The station is the interconnection point of the Noxon Rapids Hydro Electric Dam as well as a
principal interconnection point between Avista and BPA, and as such is a significant asset in the reliable
operation of the Western Montana Hydro Complex. Equipment outages within the Station (planned or
unplanned) can cause significant curtailments of the local generation output. Due to the significance of
the station, a complete rebuild will require coordination with Avista’s Energy Resources Department and
neighboring utilities, primarily BPA. The Noxon Switchyard Rebuild Project is proposed to be a greenfield
Double Bus Double Breaker 230 kV switching station to replace the existing Noxon Switchyard.

Business Case Description:
This program maintains our fleet of Power Transformers and High Voltage Circuit Breakers. This fleet of
critical apparatus is capitalized upon receipt and placed in service for both planned and emergency
installations as required. The annual program expenditures may vary significantly in years when an
Autotransformer (230/115 kV) is purchased. In years without an Autotransformer purchase, only minor
variations will occur based on planned projects as well as replenishing apparatus fleet levels required for
adequate capital spares. These are long lead time items so apparatus levels need to be managed.

Approved Business Case Spend Amount 2016‐2017 ($000s ‐ System): $4,1001
Transfer to Plant Amounts ($000s ‐ System):
Business Case Description:
The Distribution Transformer Change‐Out Program has three main drivers. First, the pre‐1981 distribution
transformers that are targeted for replacement average 42 years of age and are a minimum of 30 years
old. 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 potential to have pcb containing oil.
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 the risk of pcb containing oil spills which are a safety, environmental,
and a public relations concern.

Business Case Description:
Avista has hydro, transmission/distribution and substation facilities on the Coeur d'Alene, Colville,
Flathead (Salish/Kootenai), Nez Perce and Spokane Tribe Reservations. These facilities are essential
components of our energy resource and delivery systems. Avista is required to obtain permits from the
Bureau of Indian Affairs (BIA) for its facilities on land held in trust by the federal government for Tribes
and/or individual tribal members. Through some of its tribal settlements, Avista obtained the necessary
tribal consent and BIA permits for its facilities on tribal trust land. However, Avista needs to renew
approximately 700 rights of way permits for other facilities on Trust Land. The original permits were
obtained 50+ years ago and the renewal process can be time‐consuming (multiple years) and costly. Some
of the permits may be in a trespass situation. Avista is actively working with the BIA and the Tribes to file
renewal applications and complete the renewal process.

Transfer to Plant Amounts ($000s ‐ System):
Business Case Description:
Avista's south region 230 kV, primarily around Lewiston‐Clarkston, experiences excessive high voltage
during light load periods. Voltages exceed equipment ratings over 35% of the time. Operation of
equipment outside of equipment ratings imposes potential legal and regulatory risks to the Company on
top of increasing large scale outage possibilities. The ability to control MVAR flow at our BPA
interconnection will also reduce power factor penalty charges. The expected IRR, including effects, is
6.38%. With automatic control, existing over‐voltages can be reduced, if not eliminated, on the 230kV
buses at Dry Creek, Lolo, and N. Lewiston, as well as Moscow and Shawnee.

Approved Business Case Spend Amount 2016‐2017 ($000s ‐ System): $9661
Transfer to Plant Amounts ($000s ‐ System):
Business Case Description:
For capital upgrades and replacement and for O&M expenses for the jointly owned 500 kV Colstrip
Transmission System. Program funding is used as transmission assets reach end‐of‐life, requiring
replacement or upgrade. Under the Colstrip Project Transmission Agreement (among Avista,
NorthWestern Energy, PacifiCorp, Portland General Electric and Puget Sound Energy), Avista is obligated
to fund capital and O&M expenses commensurate with Avista's ownership share in these facilities. Such
facilities include hardware, software, and operating system upgrades to meet new operating standards
and requirements. Some upgrades may be initiated by NERC reliability standards, growth, and third‐party
projects (e.g. transmission or generation interconnections required by FERC policy). Examples of upgrades
under this program include: 500 kV breaker replacements, dual communication path construction to
meet NERC standards, 500 kV relay upgrades and 500 kV tower erosion mitigation. One of the Broadview
600 MVA 500/230 kV autotransformers failed in in the Fall of 2013. The Replacement for the Broadview
transformer was budgeted to be funded in 2015 (Avista share estimated to be approximately $125,000
with estimated $91,000 insurance credit in 2015). Planned purchase of a spare 600 MVA 500/230 kV
autotransformer in 2015 ‐ Avista share estimated to be approximately $450,000.

Approved Business Case Spend Amount 2016‐2017 ($000s ‐ System): $20,0001
Transfer to Plant Amounts ($000s ‐ System):
Business Case Description:
The Distribution Grid Modernization Program provides value to customers and shareholders by improving
Grid Reliability, Energy Savings and Operational Ability through a systematic and managed upgrade of our
aging distribution system. This program seeks cost effective opportunities to increase service quality
performance and system availability through the identification of locations that would benefit from the
addition of switched capacitor banks, regulators and smart grid devices. The long‐term plan represented
by the IRR of 6.4% aims to upgrade 6 feeders per year to cover the whole distribution system in a 60 year
cycle. This coordinates well with Wood Pole Management's 20 year cycle. The average cost to rebuild
each feeder is estimated to be $3.5M.

Business Case Description:
The Company's Distribution Grid system includes 18,000 circuit miles of overhead and underground
primary conductors. As load and generation patterns shift, certain areas (segments) of the system
become thermally overloaded. These constrained portions of the system are identified through
systematic planning studies or from operational studyworks conducted by Area Engineers. In addition,
FDR 'Tie' switches are installed to allow load shifts between FDR circuits to balance loads and in response
to either maintenance or forced outages.
