A VISTA CORPORATION RESPONSE TO REQUEST FOR INFORMTION JUSDICTION: CASE NO: REQUESTER: TYE: REQUEST NO.: IDAHO AVU-E-10-01 / AVU-G-10-01 IPUC Production Request Staff-079 DATE PREPARD:WISS: RESPONDER: DEPARTMNT: TELEPHONE: 06/04/2010 Don Kopczyski Mark Weiss Engineerng (509) 495-2034 REQUEST: In Ehrbar's testimony, page 5, lines 4-7, regarding why the Company is proposing an increase of such magntude in the customer/basic charge, he says "A signficant portion of the Company's costs are fixed and do not var with customer usage. These costs include distrbution plant and operating costs to provide reliable service to cutomers." (Emphasis added). He then says this again on page 32, lines 20-23. Given the recent outage on May 3rd that left 18,000 customers without power thoughout the Eastern Washington and Nort Idaho serce tertory, please explain what the Company's crteria is for determining the perormance reliability it provides to customers. Please include as part of your response an explanation of: a. How the Company quantifiably measUres its reliabilty perormance. b. How the Company incorporates the measurement parameters included in the "IEEE Guide for Electrc Power Distrbution Reliabilty" to make distrbution plant and operating investment decisions. c. How the Company uses its Outage Management System (OMS) to determine what, where and how much improvement is needed. d. How the Company measures circuit perormance, determnes its tree trmming cycle, determines outage locations, dispatches crews to trouble areas, and identifies outages as uncontrollable events. e. The causes of momentar and sustained outages over the last 5 years. RESPONSE: Avista uses several criteria to provide reliable electrc serice to its customer in Washington and Idaho. Depending on the criteria, specific capital, O&M and maintenance projects/programs are budgeted for on an anual basis. These projects are prioritized and matched against available fuding levels to determine which projects/programs are fuded each year. Ths discussion is mostly about the electrc distrbution system; however some of the reliability information does include Electrc Transmission impacts. Page 1 of4 . . . Electrc energy is required to be delivered at a ver high degree of availabilty to the customer within specific voltage tolerances which are defined by ANSI C84.1 - "Amercan National Standard for Electrc Power Systems and Equipment-Voltage Ratings (60 Her)." Ths National Standard is often adopted into state law. The distrbution of electrc energy is also limited by the thermal characteristics of the many pieces of equipment it flows though. To maitai the above critera, specific types and sizes of equipment are constrcted to serve individual customer(s) or areas with a lot of individual customers. The specific tyes and sizes of equipment are defined by additional ANSI standards, ANSI C2 - ''National Electrcal Safety Code", and Electrca and Civil Engineering calculations/judgment. Ths type of equipment is designed and expected to be long lived and to withstand the varous physical and environmental conditions of the utilty servce terrtory. Temperature is one of the environmental conditions. All of ths initial equipment installation implies a fixed level of costs whether serng a single customer or many customers. Customer expectations are for very high levels of reliabilty often measured by number of "9' s" of availabilty. For the Avista serice terrtory over the year 2009, one measure of reliabilty was measured at 99.963%. Ths translates to a System Average Interrption Duation Index of 193 minutes. In early 2000, Avista worked with the Washigton Utilities and Transportation Commission (WC) and other Washington Investor Owned Utilities to develop a program to measure the reliability of the electrc system with each Utility's serce tertory. These requirements are par of the Washington Administrative Code 480-100-398 "Electrc servce reliabilty reports", which are filed anually. Avista filed the first anual report for year-end 2001. Between 2000 and October of 2005, Avista developed and implemented an Outage Management Tool (OMT or OMS) based off of the Avista Facilties Management Geographical System (GIS) to improve the outage response and to provide better and more consistent outage information. The reporting of the reliability information is based off of the IEEE Guide for Electrc Power Distrbution Reliabilty Indices, IEEE P1366. Even though the anual reliability reportg requirements are for Washington only, Avista reports information on the entie Avista serce terrtory. For the discussion below, a sustained interrption of electrc servce (outage) is defied to be longer than 5 minutes in duration. An interption of serice that is 5 minutes or less in duration is defined as a momentar interrption. For more information and detailed explanation of several of the IEEE Reliabilty Indices, please refer to the Avista Anual Electrc Service Reliabilty Monitorig Report(s) provided as Staff PR 079-Attachment. a. How the Company quantifiably measures its reliabilty pedormance - A vista calculates several of the Indices defined in IEEE P1366 on a monthly/anual basis and analyzes the results perodically. Each of the individual indices provides a measurement of the overall system or individual feeder. One of the anual calculations is to determine the level of daily system average duration that defines what a Major Event Day (MD) is. A MED is outage incidents that are statistically not normal and represent an event that should be studied separately and outside of the normal Indices. The outage event on May 3rd 2010 was a Major Event Day for Avista. b. How the Company incorporates the measurement parameters included in the "IEEE "Guide for Electrc Power Distrbution Reliabilty" to make distrbution plant and operating investment decisions - Over the last two years, the reliabilty information has shown an increase in both the number of sustained interptions of servce and also the system average lengt of sustained interptions. As par of the reporting requirements, an area of concern has been defined and specific plans developed to address the reliabilty concers. Ths area is in the Page 2 of4 .Washington portion of the A vista servce terrtory. Some additional specific feeders in the Idaho serice terrtory have been identified and capital projects completed in the last two years. There are additional projects planed in the futue. One specific project was the completion of the Sagle Substation and associated feeder work to reduce the outages experenced by all of the customers on ths long distrbution feeder system. In 2009, A vista had numerous planed outages to improve the reliability of the Elk City distrbution line out of Grangeville, Idaho. Work was completed for both Wood Pole Management and also changing the framing on cerain sections of the feeder that were problematic. c. How the Company uses its Outage Management System (OMS) to deterine what, where and how much improvement is needed - The OMS provides a significant amount of data including location, A vista Offce area, reason/sub-reason for sustained interrption, and the specific feeder. One of the ver useful tools is to geospatially plot the sustaned outage information on a GIS area map and look at the customer(s) impacted by the outage(s). These plots are available in Staff YR _ 079- Attachment. The "reason" causes and any notes from the line operating personnel responding to the outage are reviewed to deterne what and where to implement changes to the feeder. Engineering personnel wil tyically meet with the local operating personnel to discuss the improvements that are planed and then develop the specific jobs to complete the work. How much improvement is needed is still based on engieerg judgment and how much improvement actually occurs with work completed on the area. d. How the Company measures circuit performance, deterines its tree tring cycle, determnes outage locations, dispatches crews to trouble areas, and identifies outages as uncontrollable events - . Individual circuit performance measurements were described above. A vista has done analysis and has extensive experence in determining the curent tree trmmg cycle for both the Electrc Transmission and Distrbution System. The industr (utilities, PUDs, Muncipalities) also reflects varous trmmng cycles from 18 months to five years, with most utilities utilzing a five (5) year cycle for distrbution line clearance. Trimming cycles are based on regional tree growt rates and available fuding. Triing cycles provide inspection and maitenance on a regular basis, and an abilty to identify and remove high-risk trees in a timely fashion. Site and species are a consideration in all vegetation management programs, and trees are prued so adequate clearance can be maitained between the tree and the overhead lines between cycles. The shorter the tring cycle, the less live biomass (branches) that needs to be removed, and the amount of prug required for each cycle is signficantly reduced. This assumes the trmming is completed on a regular, established cycle. Avista's goal is (and Asset Management Modeling has shown) a five (5) year cycle would be the optimal multiple year work plan for A vista distrbution vegetation management program. Components of determining the multiple year work plan include tree related outage data last trm date, and conversations with the local offce operating personneL. The 2010 work plan is based on curent fuding levels and a projected cost per mile of circuit trmmed (from historical average anual cost per mile data). The Company's curent vegetation management plan includes a six (6) plus year cycle..The Transmission Vegetation Management plan relies on a major reclearng activity that is done on a ten to fifteen year cycle based on vegetation condition obsered during line patrols. Minor reclearng and hazard tree work or spot work is identified durg anual line patrols Page 3 of4 , (aerial and ground patrols) and from reports from line servcemen, field personnel and the System Operator..Avista implemented an Interactive Voice Response system (IV) that provides the star of the sustained outage duration and customer location to the OMS. A distrbution dispatcher is notified of the outage incident(s). As the customer calls come in, they can bundle the incident together to a common device that may have resulted in the outage. A crew is called and assigned to the incident to resolve. The assigned crew then responds and makes an assessment of the outage cause and takes corrective action. If the number of incidents (such as a storm) becomes very large, additional resources are assigned in Distrbution Dispatch, outages are prioritized, resources are assigned to provide intial assessment and material needs before a crew is assigned to that outage area. After each outage event/incident is closed out, the Dispatcher assign a Reason and Sub-reason cause to the outage from information the operating personnel provide. The Reason and Sub-reason cause codes provide some abilty to determine the difference between a "planed" outage versus an "unplaned" outage. See the Reason and Sub-reason cause code descriptions in Staff_PR-079-Attachment. e. The causes of momentar and sustaned interrptions over the last 5 years. .

Introduction Washington state investor-owned electnc companies are to provide statements describing their reliabilty monitoring in an anual report pursuant to WAC 480-100-393 and WAC 480-100-398. This document reports Avista Utilties' reliabilty metrics for the calendar year 2009. All numbers in this document are based on system data. The Company's system includes eleven geographical divisions. Two of these divisions straddle the Washington and Idaho border and commingle jursdictional customers. A map of Avista's operating area is included in a following section. WAC 480-100-393 (3)(b) requires the establishment of baseline reliabilty statistics. The Company's baseline statistics are included in this report. A vista continues to review its baseline reliabilty statistics in light of operational experience under this regulatory protocol. A vista may modify its baseline statistics as appropnate and wil update the Commission accordingly. Avista added a new section to the 2007 anual report which analyzes the areas where customers are expenencing multiple sustained outages. This new section provides analysis of a reliability indice called CEMIn, which implies Customers Expenencing Multiple sustained Interrptions more than n times. Avista Utilities 2009 Service and Reliabilty Report Draft 04/16/2009 StafLPR_079 Attachment 1 Page 50f66 . Data Collection and Calculation Changes WAC 480-100-398 (2) requires the Company to report changes made in data collection or calculation of reliabilty information after initial baselines are set. This section addresses changes that the Company has made to data collection. Data Collection . Since Avista's Electrc Service Reliability Monitorig and Reporting Plan was filed in 2001, there have been several improvements in the methods used to collect outage data. In late 2001, centralizing the distribution trouble dispatch and data collection fuction for Avista's entire service terrtory began. The distribution dispatch offce is located in the Spokane main complex. At the end of September 2005, 100% of the Company's feeders, accounting for 100% of the customers, are served from offces that employ central dispatching. The data collected for 2009 represents the four full year of outage data collected though the Outage Management Tool (OMT). For 2009, all data was collected using the "Outage Management Tool" (OMn based on the Company's Geographic Information System (GIS). The OMT system automates the logging of restoration times and customer counts. .A vista did discover a software coding error that has been within the OMT system since 2002 that wil cause a small increase in the SAII and CAIDI for 2008. Previous years were also evaluated to determine the overall impact to the A vista baseline statistics and at this time A vista is not proposing a change to the baseline numbers. The softare error only occured during very specific outage conditions when a group of customers with an initial outage starting time were "rolled" up into another group of customers that were determined to be par of the first group outage. The second group may have had a later outage staing time. When the first group of customer outage information was rolled up, the original outage staing time was lost and the second group outage staring time was used for both groups of customers instead of using the fist outage startng time. The number of customers was counted correctly. Even as good as the OMT system is at quantifyng the number of customers and duration of the outage duration, there stil are areas where the data collection is not precise. Determinng the exact staing time of an outage is dependent on when a customer calls in, how well the A vista Distrbution Dispatcher determines where the outage is and defies the device that has opened to remove the faulted section. As AM AM metering is implemented in the futue and the customer meter provides outage information to the OMT system though an interface, the SAII and CAII numbers are expected to increase. This is similar to the above discussion. Use of the OMT system and GIS data has improved the tracking of the numbers of customers without power, allowed for better prioritization of the restoration of service and the improved dispatching of crews.. Avista Utilities 2009 Service and Reliabilty Report Draft 04/16/2009 StafCPR_079 Attchment 2 Page 6 of 66 . . . . A vista has reported in the previous anual reports that the completion of the transition to the OMT system had caused an increase in the variability of the data collected from 2001 to 2007. This Anual Report continues to show that a gradual increase in the SAIFI and SAII numbers that canot be attbuted to the transition to the OMT system. Review the chars, on pages 9 and 12 that provide a trend line for SAII and SAIDI historical data. Continued scrutiny wil be importt over the next year or so to determine if the increase in SAIFIISAIDI continues, or can be slowed or reversed by reliabilty improvement programs implemented in 2009 and underway in 20 I O. If it canot be slowed or reversed to examne if this is drven by other sources or conditions not recognized yet. See SAII Linear Trend Line Chart later in this document. Interruption Cause Codes Cause code information is provided in this report to give readers a better understading of outage sources. Furher, the Company uses cause information to analyze past outages and, if possible, reduce the frequency and duration of futue outages. . The Company made several changes in the classification of outage causes for the reporting of 2005 outages and subsequent years. Customers Experiencing Multiple Interruptions The IEEE Standard 1366P-2003 provides for two methods to analyze data associated with customers experiencing multiple momenta interrptions and/or sustaied interrptions. Avista's Outage Management Tool (OMT) and Geographical Information System (GIS) provide the ability to geospatially associate an outage to individual customer service points. This association allows for graphically showing Customers Experiencing Multiple sustained Interrptions (CEMln) with Major Event Day data included onto GIS produced areas. Data can be exported to MS Excel to also create graphs representing different values of n. 2009 information is provided in the new section added to the 2007 report after the Areas of Concern Section to sumarize the analysis A vista performed on the 2009 outage data. The calculation for CEMIn and Customers Experiencing Multiple Sustained and Momenta Interrptions CEMSMln is provided in the Indices Section. Avista Utilties 2009 Service and Reliabilty Report Draft 04/16/2009 StafCPR_079 Attachment 3 Page 70f66 . . . Definitions Reliabilty Indices SAIFI (System Average Interrption Frequency Indices), MAIFI (Momentary Average Interrption Frequency Indices), SAII (System Average Interrption Duration Indices), and . CAIDI (Customer Average Interrption Duration Indices) are calculated consistent with industr stadards as described below. Avista adopts these for puroses of tracking and reporting reliabilty performance. Furher explanation and definitions are provided in the "Indices Calculation" section of this report. While these indices are determined using industry standard methods, it is important to note that differing utilties may use different time intervals for momenta and sustained outages. Avista defies momenta outages as those lasting five (5) minutes or less. Sustained outages are those lasting longer than five (5) minutes. Baseline Reliabilty Statistics WAC 480-100-393 (3) (b) requires the establishment of baseline reliability statistics. The Company's 2003 Electrc Service Reliabilty Monitoring and Reporting Plan initially established Avista's Baseline Reliabilty Statistics. At that time, the Company selected the baseline statistics as the average of the 2001 though 2003 yearly indices plus two standard deviations (to provide 95% confidence level). In 2006 the Company reviewed the calculation of the baseline statistics in light of the completion of the transition to the GMT in 2005 and the data collected in 2006. Calculating the baseline reliability statistics including the 2004 though 2006 data show an increase in the values, which the Company believes, represents better reporting using GMT. The Company proposed the latest calculated Baseline Statistic values to reflect the best available data collection. Because the Company believes that the GMT data collection has affected the SAII index the most it used the years 2004 to 2006 for the SAIFI Baseline Statistic and the years 2002 to 2006 for the MAI and SAII Indices. The baseline indices have been adjusted by removing Major Event Days, MED's, as defined in the following section. The following table sumarzes the baseline statistics by indices. 2004-2006 Baseline Indices Average Statistic ~xcmdin2 Mmor Evenæ)(Ave + 2 Stadard Deiations) SAIFI 1.09 1.44 2002-2006 Baseline Indices Average Statistic ~xciudi2 Maior Evenæ)(Ave + 2 Stada Deations) MAIFI SAIDI 4.52 114 5.82 160 Avista Utilities 2009 Service and Reliabilty Report Draft 04/16/2009 StafLPR_079 Attachment 4 Page 8 of 66 . . . Additional comparison of the Baseline Indices is provided in the System Indices section of this report. A vista is anticipating using the different years in the Baseline Statistics for SAIFI for a few years until a full five years of data is gathered using the curent Outage Management TooL. Avista Utilties 2009 Service and Reliability Report Draft 04/16/2009 StafCPR_079 Attachment 5 Page 90f66 . Major Events Major Events and Major Event Days as used in this report are defined per the IEEE Guide for Electric Power Distribution Reliabilty Indices, IEEE P1366-2003. The following definitions are taken from this IEEE Guide. Major Event - Designates an event that exceeds reasonable design and or operation limits of the electric power system. A Major Event includes at least one Major Event Day (MED). Major Event Day - A day in which the daily system SAIDI exceeds a theshold value, T MED. For the puroses of calculating daily system SAIDI, any interrption that spans multiple calendar days is accrued to the day on which the interrption began. Statistically, days having a daily system SAII grater than T MED are days on which the energy delivery system experenced stresses beyond that normally expected (such as severe weather). Activities that occur on major event days should be separately anlyzed and reported. The Company wil use the process defined in IEEE P1366 to calculate the theshold value ofTMED and to determine MED's. All indices wil be reported both including and excluding MED's. The comparisons of service reliability to the baseline statistics in subsequent years wil be made using the indices calculated without MED's. The table below lists the major event days for 2009. .Major Event Days SAlOl (Customer- Minutes) Cause 2009 Major Event Day Threshold 9.925 No Major Event Days Additional analysis of the 2009 Major Event Days is not provided in this Anual Report as was done in previous years staing on Page 53, section Major Event Days Causes. . Avista Utilities 2009 Service and Reliability Report Draft 04/16/2009 StafCPR_079 Attachment 6 Page 10 of 66 . . . Customer Complaints The Company tracks reliability complaints in two areas, Commission Complaints and Customer Complaints. Commission Complaints are informal complaints fied with and tracked by the Commission. Customer Complaints are recorded by our Customer Service Representatives when a customer is not satisfied with a resolution or explanation of their concern. See the Customer Complaints section on Page 36 for a summar of results for this year. System Indices The charts below show indices for Avista's Washington and Idaho ("system") electrc service territory by year. Breakdown by division is included later in this report. The Company continues to use the definition of major events as described above to be consistent with IEEE Standards.

SAIFI for 2009 was over the existing baseline established in 2006 and represents the increasing trend. Using a simple linear regression to establish a trend line, it would look like about a 9.9% growth in number of customers affected. The R2 coefficient of determination shows a much stronger correlation to the data than last year. A char of this analysis has been provided just after this discussion. Major contrbutors to this higher number of customers affected were animals, planed outages, undetermined, and weather. Avista Utilties 2009 Service and Reliability Report Draft 04/16/2009 StafCPR_079 Attachment 8 Page 12 of 66 .There were 138,951 customers affected by sustained outages caused by weather in 2009. This compares to the 2004-2008 average of 83,395 customers. 51,024 customers were affected by sustained outages associated with animal related incidents. This compares to the 2004-2008 average of28,233 customers. The vast majority of the animal related reasons were associated with squirrel caused incidents. Planned maintenance activities and also forced repairs affected 52,838 customers as compared to the 2004-2008 average of 24,845 customers. Continued maintenance activities associated with the Company equipment replacement program contrbuted to the increase in this cause and reduced the Overhead Equipment outage causes. An increase in the number of Undetermned Causes occured in 2009 as compared to the 2004- 2008 average. 92,117 customers had undetermined causes as compared to the average of 43,835. A large number of outages were associated with transformer fuses, but there was no known reason for the fuse to operate. Additional analysis in 2009 along with discussions with local area personnel could only suspect these maybe animal caused as the common element that is suspected. No evidence can be contrbuted to these outages. SAIFI Linear Trend Line Chart .1.60 . 1.40 1.20 1.00 . 0.80 0.60 0.40 0.20 0.00 2002 2003 2004 2005 Linear Trend for SAIFI without MED's ..

The 2009 results for MAIFI show a large decrease over 2008 and about the same as 2007 levels. There was a reduction in weather related momentary outages that canot be explained on weather conditions alone. There was a corresponding increase in the number of undetermined outages, which can reflect that weather conditions did cause outages. Distrbution Dispatch continues to make improvements in correlating the momenta outages with subsequent sustained outages, which reduces the undetermined causes. All other categories showed either a slight decrease that would be consistent with previous years.

Areas of Concern As in previous years, Colville continues to have the lowest reliability of Washington's operating areas. However, the Colvile area continues to show improvement over previous years as work plans are implemented. Colvile was judged lowest based on its performance in the yearly indices for SAII, SAII, CAIDI, and MAIF!. Within the Colvile area, six feeders were identified as the areas of concern for 2009. These feeders are Gifford 34F1, Gifford 34F2, Colvile 34F1, Colvile 12F4, Valley 12F3 and Valley 12Fl. For this report, these same six feeders are identified as the areas of concern for 2009. Cause Information: Generally rual areas have a greater number of outages per customer. Colvile is a predominately rual and forested area. There are approximately 2342 miles of distribution line exposed to weather, underground cable failures and tree problems. Unlike most of the Company's system, lines in this area are built on the narow, cross-countr rights-of-way, tyical of PUD constrction practices prior to A vista acquirg the system. These conditions make patrollng, tree trimming, right of way clearng and other maintenance difficult. When cost effective, Avista moves sections of these overhead lines to road rights of way and/or converts them to underground. Furher, when outages occur in rual areas, the time required to repair daage is longer. More time is required for first responders to arve and assess the daage and more time is required for the crew to reach the site. Often the damage is off road and additional time is required to transport materials and equipment to the site. Listed below is a summary of the specific cause data for each feeder. This is a compilation of data from the Avista Outage Management Tool and the reportng from our local servcemen to Distrbution Dispatch. Data from the reportng system is shown as a percentage of total customer- outages, (SAII) for that feeder. Snow loading on green healthy trees growing beyond the rights-of-way often causes them to bend or break and contact distribution lines. These trees are not cut as par of our vegetation management program because they are outside our right of way and are considered healthy marketable timber.

Colville Area Work Plans: The improvement work that has been accomplished or planed for each feeder is listed below. The Company's reliability workig group is continuing to study these feeders to develop additional work plans. Each of the identified feeders also had planed outages that correspond to the maintenance and replacement activities in the area. Gifford 34Fl . 10,300' ofUR cable was replaced in 2009, and 12,850' ofUR cable is planed for replacement in 2010. . A reliabilty improvement project is scheduled for 2010 in the Pleasant Valley area of this feeder to replace (42) 1940 class poles with new poles and replace approximately 2.2 miles of I-phase #6A, #6CW, and #9 1/2D wire (all in poor shape) with 2-phases of #2ACSR wie. . Vegetation Management completed tree trmmng of698 trms and 522 tree removals in 2009. No work planned for 2010. Colvile 34Fl . 12,350 ofUR cable was replaced in 2009. None is scheduled to be replaced on this feeder in 2010 . A capital improvement project was completed in 2009 to replace 2.2 miles of 3-phase #6 Crapo wire in poor condition in a difficult access area with 3-phases or UR cable. . A reliabilty improvement project is planed for 2010 to perform an RF surey of the tr of this feeder and pedorm follow-up work to address issues that are found. . Vegetation Management completed 6 tree trms and 713 tree removals in 2009. No work planed for 2010. Chewelah 12F3 . 7700' ofUR cable was replaced in 2009, and 5200' ofUR cable is planed for replacement in 2010. . A reliability improvement project was completed in 2009 to split the Chewelah 12F3 into two feeders (Chewelah 12F3 and Chewelah 12F4). Also, another reliabilty project was completed to convert 2- miles of I-phase overhead line with bad access with 2-phases of UR. . Late December 2009 saw the completion of the new Chewelah 12F4 feeder, which split the existing 12F3 into two par. The origial 12F3 feeder was almost 66 miles in circuit miles and is now about 26 circuit miles. 12F4 wil be about 40 circuit miles. Gifford 34F2 . 2775' ofUR cable was replaced in 2009, and 8510' ofUR cable is planed for replacement in 2010. . A reliabilty improvement project is planed for 2010 to convert 3.5 miles of3-phase overhead line to UR in the Twin Lakes area near Inchelium. Valley 12F1 . No UR cable was replaced in 2009, but 300' ofUR cable is planed for replacement in 2010. Avista Utilities 2009 Service and Reliability Report Draft 04/16/2009 StafCPR_079 Attchment 18 Page 22 of 66 . . . . A reliability improvement project was completed in 2009 to convert 1.9 miles of I-phase overhead line to UR in the Hesseltine Rd. area. . Another reliabilty improvement project is planed for 20 I 0 to convert 3.2 miles of 2- phase overhead line to I-phase UR in the Jepsen Rd area. Valley 12F3 . 1300' ofUR cable was replaced in 2009, and 700' ofUR cable is planed for replacement in 2010. . Vegetation Management completed 749 tree tris and 293 tree removals in 2009. A small amount of work is planed for 2010. Avista tyically uses several different protective devices on its feeders to isolate faulted or overloaded sections and also continue to serve the remaining customers. Generally, two different protection schemes are used to either "save" the lateral fuse or "blow" the lateral fuse by using or not using the instantaneous over curent trp. Depending on the feeder, number of customers, tyes of faults, (temporary or permanent), customer tye, time of year, etc. both of these schemes may be used on an individual feeder at different times at the discretion of the field personneL. With the better data and cause code collection that GMT provides and the customer growth on some of the Colvile feeders, changes to the tye of scheme used has been reviewed. Listed below are major reliabilty projects specifically identified by feeder. Three of these are in the State ofIdaho.

Avista Utilties 2009 Service and Reliability Report Draft 04/16/2009 StafCPR_079 Attchment 19 Page 23 of 66 . . . Avista System Wide Work Plans: A vista develops a detailed annual budget for various improvements to the facilities it owns and operates. For 2009, three reliability feeder projects (one has been deferred to 2010) were completed and described above. The reliabilty improvement should show up over the next couple of years. Additionally Asset Management has developed some specific projects that are expected to improve reliabilty on several feeders system wide. These projects are summarzed in the table below. Porcelain cutout replacements were completed at the end of 2009. During 2009, Avista looked at the possibilty of performng extensive constrction and rehabiltation of the Ninth and Central 12F4 feeder in Spokane. This included reconductoring specific sections ofline for loss improvement, changig transformers that were older than 1983, replacing many long seconda districts, and replacing many wood poles. Reliability in 2009 was degraded due to the many planned outages, however only two non planed outages have been reported in early 2010. Additional review wil be done for the year end 2010. Material records show that some wildlife guards were installed on new distrbution transformers installations starting in the mid 1980's. With the recognition of increases in animal caused outages, new materials and improvements have been made in the constrction standards for new distribution transformer installations to reduce these tyes of outages. Initial indications show that the outage reduction on a feeder after wildlife guards are installed is significant. 2009 was the sta of the multiyear wildlife guard installation program to reduce the squirel and bird related outages on approximately sixty feeders in Washington and Idaho. Most of the wildlife guards were installed with a hot stick on existing transformers that do not have an existing wildlife guard. Avista installed a total of 4534 wildlife guards on 20 feeders in 2009. There were 2130 wildlife guards installed in Idao on 9 feeders and 2404 wildlife guards installed in Washington on 11 feeders. One feeder (Orin l2F3) in the Colvile area had wildlife guards installed last year. A vista deferred plans to install wildlife guards on additional feeders in Washington for 2010 due to unfavorable pro-forma rate treatment of the program. Avista wil continue with plans to install wildlife guards in the State ofIdaho. 9 feeders are planed to have wildlife guards installed. Asset Management in conjunction with the Wood Pole Management Program stubbed or replaced numerous poles and additionally replaced numerous pole top transformers and associated cutouts/aresters. Avista System Wide Vegetation Management Plan: A vista has an anual vegetation management plan and budget to accomplish the plan. The budget is allocated into distribution, transmission, admistration, and gas line reclearg. Distrbution Our curent plan for Avista's distribution system is managed by Asplundh Tree Expert Co. Every distrbution circuit is scheduled to be line clearance prued on a regular maintenance cycle of four year urban and seven years rual. Other distrbution vegetation management activities include hazard tree patrol and herbicide application.Avista Utilties 20 2009 Service and Reliability Report Draft 04/16/2009StafCPR_079 Attachment Page 24 of 66 . . . Transmission The transmission system is managed by Avista's forester. All 230 kV lines are patrolled anually for hazard trees and other issues, and mitigation is done in that same year. Approximately one third of 115 kV transmission system is patrolled annually for hazard tree identification, and assessment of right of way clearing needs. Right of way clearg maintenance is scheduled and performed approximately every ten to fifteen years (for each line). Interim spot work is done as identified and needed. Engineering specifications for varous voltages, line configuations are followed when clearing the right of way. Curently, the work is bid to a variety of contractors. Customers Experiencing Multiple Interruptions A vista has used the data from the OMT system integrated with the GIS system to geospatially display reliabilty data for specific conditions. The specific conditions imply looking at the number of sustained interrptions for each service point (meter point). This would be similar to the SAIFI indice, but would be related to a certin number of sustained interrptions. A vista includes all sustained interrptions including those classified under Major Event Days. This provides a view of what each customer on a specific feeder experiences on an anual basis. Momentar Interrptions are not included in the CEMln indice, because of the lack of indication on many of the rual feeder reclosers. The first char below provides a view of the percentage of customers served from the A vista system that have sustained interrptions. 65 % of A vista customers had 1 or fewer sustained interrptions and 5.4% of Avista customers had 6 or more sustained interrptions durg 2009. The remaining geographic plots show the sustained interrptions by color designation according to the legend on each plot for each office area. Note the office area is designated as the area in white for each plot and that there is overlap between adjacent offce area plots. The adjacent offce areas are shown in light yellow. The plots provide a quick visual indication of varng sustained interrptions, but significant additional analysis is required to determine underlying cause(s) of the interrptions and potential mitigation.

MED - Major Event Day A major event day is a day in which the daily system SAII exceeds a theshold value. Its purose is to allow major events to be studied separately from daily operation, and in the process, to better reveal trends in daily operation that would be hidden by the large statistical effect of major events. T MED is calculated (taken from the IEEE 1366-2003 Standard) The major event day identification threshold value, T MED, is calculated at the end of each reporting period (typically one year) for use during the next reporting period as follows:a) Collect values of daily SAlOl for five sequential years ending on the last day of the last complete reporting period. If fewer than five years of historical data are available, use all available historical data unti five years of historical data are available. b) Only those days that have a SAlOl/Day value wil be used to calculate the T MED (do not include days that did not have any interruptions). c) Take the natural logarithm (In) of each daily SAlOl value in the data set. d) Find cx(Alpha), the average of the logarithms (also known as the log-average) of the data set. e) Find ß(Beta), the standard deviation of the logarithms (also known as the log-standard deviation) of the data set. f) Compute the major event day threshold, TMED, using equation (25). T - e(Ol+ 2.5 ß)MED-(25) g) Any day with daily SAIDI greater than the theshold value TMED that occurs during the subsequent reporting period is classified as a major event day. Activities that occur on days classified as major event days should be separately analyzed and reported.. .

In your response, please provide an executable electronic summar ilustrating each class's anual percentage of Idaho dual servce customers over the last 10 years. RESPONSE: On page 16 in his testimony, Mr. Ehrbar noted that the only economic effciency for dual servce customers is a reduction in biling expenditues. A recent estimate of the cost of biling (bil preparation, paper supplies, postage, etc.) was 54.3 cents per bilL. Other potential savings for dual service customers usually relate to servces and meter reading. As he discusses in his testimony, there are no savings of dual serces as both require separate facilties to provide servce. Furer, regarding meter reading, electrc and natual gas meter reading has been automated in our Idaho facilties. The reduction in meter reaing expenses have already been included in the Company's rates. It is important to note that, even with the savings of 54.3 cents for dual servce customers, far more fixed costs of providing serce to our customers (dual serce or not) are not being recovered in the basic charge. The Company believes that it is appropriate to recover a more reasonable level of these fixed customer costs though the basic charge. StafCPR _ 089 Attachment A is an executable electronic sumar ilustrating each rate schedules anual percentage ofIdaho dual servce customers from 2003 through 2009 (seven years).

(509) 495-2204 REQUEST: Please provide a narative description of how the collaborative group decides which projects to approve, and how much to expend per project. RESPONSE: Avista owns and operates the Noxon Rapids and Cabinet Gorge hydroelectrc developments (Clark Fork Project No. 2058). The operation of the Clark Fork Project is conditioned by the Clark Fork Settlement Agreement (CFSA), signed in 1999, and Federal Energy Regulatory Commission (FERC) License No. 2058, effective date of March 1,2001. The CFSA and FERC license established Protection, Mitigation and Enhancement measures (PM&Es). The CFSA and FERC license also established a number of committees and a process for the review and approval of the implementation of all the PM&Es (see attached organizational char). . The ultimate decision makng body is FERC, however, prior to A vista requesting FERC approval, all proposed PM&E activities are approved by the Clark Fork Management Committee (MC). The MC is comprised ofthe 28 signatories to the CFSA. The MC includes representatives from federal, state, and local governent, five Native American trbes, non-governental organizations and A vista. The MC strves to make all decisions, including approval of planed activities and expenditues, by consensus. The anual approval process begis on December 1 st of each year, when the first drafts of Anual Implementation Plans (Als) are due to Avista. These draft Als are prepared by stakeholders and/or Avista. During this month all aquatic Protection, Mitigation and Enhancement (PM&E) Als (CFSA Appendix A, B, C, D, E, Fl, F2, F3, F4, F5 and T) are reviewed by the Aquatic Implementation Team (Avista, IDFG, MFWP and USFWS fishery biologists). The first drafts for the terrestral PM&Es are also due December 1 st of each year, and are developed by Avista with input of our stakeholders. Depending upon the resource being addressed, these draft Terrestral Als are reviewed and refined by subcommittees of the Terestral Resource Techncal Advisory Committee (TRTAC established in the CFSA), such as the Riparan Implementation Team, Land Use Subgroup, or Recreation Resources Subgroup. . Following this initial review process, all proposed individual projects that deal with stream habitat restoration, habitat acquisitions/easements and total dissolved gas mitigation efforts are raned and prioritized following established Management Committee (MC) approved raning criteria. Usually, these types of proposed projects are found within Appendix A, B, Fl, H, and K. The process is undertaken by interested participants from the Water Resources Techncal Advisory Committee (WRTAC) and TRTAC composed of representatives from the CFSA signatories. . . . Page 2 After this ranng process, all of the draft Als, including the top raned stream habitat restoration, habitat acquisitions/easements and total dissolved gas mitigation projects, are collated and mailed, depending on subject category, to either the WRTAC or TRTAC for their review and consideration. The Cultual Resources Techncal Advisory Committee also receives all of the Als for their review and consideration. Formal meetings of these Technical Committees are held toward the end of Januar where all Als are reviewed, modified and/or approved to be forwarded onto the Management Committee. After a short internal editing period, all of the draft Als are collated and mailed to the MC for their review and consideration in the middle of Februar. During their March meeting, usually held in the middle of the month, the MC reviews, modifies and approves the Als for the year. All Als are then submitted for FERC approval by April 15th. Meeting notes from the Management Committee and all subcommittees are available upon request. . . .
