IPC-05- IDAHO POWER COMPANY' RESPONSE TO IDAHO IRRIGATION PUMPERS ASSOCIATION' FOURTH DATA REQUEST COMES NOW, Idaho Power Company ("Idaho Power" or "the Company and in response to the Fourth Data Request of the Idaho Irrigation Pumpers Association to Idaho Power Company dated January 6, 2006, herewith submits the following information: REQUEST NO 45: Regarding the Company s response to Irrigator Request 3b, please answer the following: Please supply a copy of this information in electronic format. Please provide the full names of each of the substations listed as well as the County in which it is located and the nearest city/town. IDAHO POWER COMPANY'S RESPONSE TO IDAHO IRRIGATION PUMPERS ASSOCIATION'S FOURTH DATA REQUEST Page It appears that the first entry for each feeder may be some sort of composite value for each feeder. Please explain the significance of those first entries and how the values for "new service" relate to the other values listed for the feeder. What do the "kWh" figures represent? Are they annual figures figure since connection , annual estimates, etc. What do the suffixes (B , P , S, CB , SB, M , etc.) mean under the rate" column? What is the significance/relationship of the first few lines that list the Feeder" as " RESPONSE TO REQUEST NO. 45(a): The requested information in electronic format is included on the CD labeled "Fourth Production Request of Irrigation Pumpers - Responses" included with this response. The response to this request was prepared by David L. Sikes, Planning Manager, Idaho Power Company, in consultation with Barton L. Kline, Senior Attorney, Idaho Power Company. RESPONSE TO REQUEST NO. 45(b): The full name of each of the substations and the county in which each substation is located are included with this response. The four-letter location code, or DIGIT4, of each substation corresponds to the first four letters of the feeder designation included on the Response to Request No. 3(b). The Company s records do not contain information regarding the nearest city/town. IDAHO POWER COMPANY'S RESPONSE TO IDAHO IRRIGATION PUMPERS ASSOCIATION'S FOURTH DATA REQUEST Page 2 The response to this request was prepared by David L. Sikes, Planning Manager, Idaho Power Company, in consultation with Barton L. Kline , Senior Attorney, Idaho Power Company. RESPONSE TO REQUEST NO. 45(c): The first entry for each feeder is the name of the feeder. The name consists of the four-letter location code and a two- digit numerical identifier. The second entry is the rate code indicating the service schedule under which the service points served by the feeder are billed. The data in the New Service" column are the counts of the service points within each rate for each feeder. Entries which do not have an entry in the "Rate" column are typically un- metered services and are not assigned a Rate Code in the Company s Geographic Information, System data base. The final column is the kWh usage within each rate for each feeder. For un-metered services the kWh usage shown in the column is zero. The response to this request was prepared by David L. Sikes, Planning Manager, Idaho Power Company, in consultation with Barton L. Kline , Senior Attorney, Idaho Power Company. RESPONSE TO REQUEST NO. 45(d): The kWh figures represent the energy for the selected customers for the period , in this case between 1/01/2004 and 11/30/2005. There is always some overlap or exclusion based upon meter read dates and the query dates. For example , if a meter existed and was read 2 January 2004 the kWh for that meter read would be included even though the actual consumption was for the time period prior and up to the actual meter reading. Similarly at the end of the defined period , energy may not be included if the meter was read after the period. If a IDAHO POWER COMPANY'S RESPONSE TO IDAHO IRRIGATION PUMPERS ASSOCIATION'S FOURTH DATA REQUEST Page 3 new metered Service Point was added in between the dates, the figure would represent the kWh since connection. The response to this request was prepared by David L. Sikes, Planning Manager, Idaho Power Company, in consultation with Barton L. Kline, Senior Attorney, Idaho Power Company. RESPONSE TO REQUEST NO. 45(e): The suffixes represent certain information related to the rate within the Company s customer information system. The suffixes P and S designate the service level within the rate , with P designating Primary Service Level and S designating Secondary Service Level. A "B" in the suffix indicates that the rate is coded with a BPA designation. This coding is meaningful for the irrigation rate schedules only and indicates eligibility for the BPA Small Farm Energy Credit. For all other rate schedules, any B designation is simply a holdover from the Company s previous customer information system. The designation "C" on Schedule 24 is used for those accounts that have five horsepower or less of connected load and indicates that the billing demand is determined based on the number of horsepower. The designation "C" on Schedule 84 indicates that the net-metering service is for commercial customers. The designation "M" indicates that the service is metered. The response to this request was prepared by Maggie Brilz, Director of Pricing, Pricing and Regulatory Services , Idaho Power Company, in consultation with Barton L. Kline , Senior Attorney, Idaho Power Company. RESPONSE TO REQUEST NO. 45(t): The service points with a "0" in the Feeder column were not yet associated with a feeder in the Geographic Information System when the query was performed. IDAHO POWER COMPANY'S RESPONSE TO IDAHO IRRIGATION PUMPERS ASSOCIATION'S FOURTH DATA REQUEST Page 4 The response to this request was prepared by David L. Sikes, Planning Manager, Idaho Power Company, in consultation with Barton L. Kline, Senior Attorney, Idaho Power Company. REQUEST NO. 46: Please provide an explanation regarding the development of the load research weighting factors. Specific information is requested regarding: When the weighting factors were developed? What steps are taken to ensure that the weighting factors are reflective of test year usage? Do the weighting factors reflect demand values or energy values? How does the Company address strata migration within its load research sample? RESPONSE TO REQUEST NO. 46(a): Stratified random sampling is the selection process whereby a population (or sample frame) is partitioned into two or more subpopulations (strata) and an independent simple random sample is drawn from each stratum. The stratum weights are determined by each stratum s share of the population. Two of the load research samples used to develop cost-of-service demand allocators in this case were stratified. The weighting factors were developed when the samples were designed. The Schedule 9 sample was designed in 2000 using billing data for the 12 months ending June 2000. The Schedule 24 sample was designed in 2002 using billing data from May through September 2000. Irrigation billing data from 2001 was not used IDAHO POWER COMPANY'S RESPONSE TO IDAHO IRRIGATION PUMPERS ASSOCIATION'S FOURTH DATA REQUEST Page 5 because consumption was affected by the temporary Irrigation Load Reduction Program. (See Case IPC-01-3). RESPONSE TO REQUEST NO. 46(b): At Idaho Power once the sample frame has been partitioned , the strata have been defined , each customer (service point) has been assigned to one and only one stratum, and a separate random sample of each stratum has been selected , the stratification process is complete. Customers are not subsequently moved to a different stratum , and stratum weights do not change. Each stratum contains a certain percentage of the total sample frame, and each stratum sample represents that portion of the entire frame. The stratum weights are appropriate for estimating ratios of the weighted average demand and energy values per customer in the original sample frame during the test year. These ratios may then be applied to the actual test year billed energy adjusted to calendar month consumption to determine system coincident and group peak demands. Alternatively, five-year median ratios may be applied to normalized calendar month energy for the test year to arrive at surrogate normalized demand values. RESPONSE TO REQUEST NO. 46(c): The weighting factors reflect the percentage of the sample frame population in each stratum and are used to estimate both demand values and energy values. Customers were assigned to strata based on their maximum monthly billed kWh during the time period used for sample design. RESPONSE TO REQUEST NO. 46(d): Some customers shift their usage patterns over time to the point where they would no longer be in their original stratum if the sample frame were restratified based on current usage. Some degree of shifting IDAHO POWER COMPANY'S RESPONSE TO IDAHO IRRIGATION PUMPERS ASSOCIATION'S FOURTH DATA REQUEST Page 6 usage by sample customers is expected and reflects normal changes in the population. The Company does not migrate customers to new strata for analysis but does recognize that shifting usage patterns may cause the strata to become less internally homogeneous as the sample ages and may lead to a deterioration of the relative precision of the sample estimates. While post-stratification is possible, it can introduce a degree of complexity and produce biased results. The Company prefers to replace the load research samples before post-stratification becomes necessary. In general, the samples are replaced every four years. The Schedule 24 sample was replaced in 1998 and 2002, and a new sample is planned for 2006. The Schedule 9 sample was replaced in 1997 and at the end of 2000. Because the Company was planning to recommend changes to the Schedule 9 eligibility criteria as part of the current rate case, it was determined that a new Schedule 9 sample should be identified at the conclusion of the case rather than in early 2005. Therefore, a new Schedule 9 sample is planned for the end of this year after the Commission has determined the outcome of the Company s Schedule 9 rate design proposal. The response to this request was prepared by Paul Werner, Load Research Team Leader, Idaho Power Company, in consultation with Barton L. Kline Senior Attorney, Idaho Power Company. REQUEST NO. 47: Regarding the Company s response to Irrigator Request 12 , there were a number of attachments provided with the extension "REP" We were unable to open these files. Could they be provided in some other format? IDAHO POWER COMPANY'S RESPONSE TO IDAHO IRRIGATION PUMPERS ASSOCIATION'S FOURTH DATA REQUEST Page 7 RESPONSE TO REQUEST NO. 47: The "REP" files are text files produced by the LodeStar system, and it should be possible to open them using a text program such as Microsoft Notepad. For convenience, the files have been reformatted and are included on the enclosed CD labeled "Fourth Production Request of Irrigation Pumpers - Responses" as "DOC" files that can be opened with Microsoft Word. The response to this request was prepared by Paul Werner, Load Research Team Leader, Idaho Power Company, in consultation with Barton L. Kline Senior Attorney, Idaho Power Company. REQUEST NO. 48: With respect to the Company s response to Irrigator Request 14 , please explain what "Bookouts" are and where they show up in the Company s FERC Form 1 , in the power cost model , and in the PCA calculation. RESPONSE TO REQUEST NO. 48: Bookouts are a simple way to eliminate the physical tagging of energy when a party has purchases and sales that occur at the same point in time, at the same location, for the same volume creating a net position of zero. When a bookout occurs , the transactions are billed as normal however no energy is tagged and no energy physically flows. There are no financial implications for bookouts , they are simply a way to reduce the unnecessary workload associated with physically tagging transactions whose volumes net to zero. The financial obligations are unchanged regardless of whether the energy actually flows or not. A bookout can be used to describe both preschedule and real time transactions. Bookouts are reported in FERC Form 1 as sales for resale and purchased power recorded in FERC Accounts 447 and 555 , respectively. Since bookouts are IDAHO POWER COMPANY'S RESPONSE TO IDAHO IRRIGATION PUMPERS ASSOCIATION'S FOURTH DATA REQUEST Page 8 normal sales and purchases , they are treated as such in the Company s PCA calculations. Bookouts do not occur in the Company s power cost modeling. The response to this request was prepared by David Bean , Controller Power Supply, Idaho Power Company, and Gregory W. Said , Manager, Revenue Requirement, Idaho Power Company, in consultation with Barton L. Kline , Senior Attorney, Idaho Power Company. REQUEST NO. 49: The data provided in the company s response to Irrigator Request 22g for June 2004 appears to have inappropriate numbers supplied for the price of these sales. Please supply the correct values. RESPONSE TO REQUEST NO. 49: Line 1020, Deal # 157605 included in the data file provided in the Response to Request No. 22(g) showed the incorrect price for the transaction; however, the total dollars shown for the transaction were correct. There was an after-the-fact correction made to this transaction during the checkout process to record the correct transaction dollar amount; a correction to the price was not made at the same time. The file included on the CD labeled "Fourth Production Request of Irrigation Pumpers - Responses" provided with this response reflects the correction to the price. All other data included in the file provided in the Response to Request No. 22(g) is correct. The response to this request was prepared by David Bean , Controller Power Supply, Idaho Power Company, in consultation with Barton L. Kline, Senior Attorney, Idaho Power Company.
