IPC-05- IDAHO POWER COMPANY' RESPONSE TO IDAHO IRRIGATION PUMPERS ASSOCIATION' SECOND DATA REQUEST COMES NOW , Idaho Power Company ("Idaho Power" or "the Company and in response to the Second Data Request of the Idaho I rrigation Pumpers Association to Idaho Power Company, herewith submits the following information: REQUEST NO. 29: Regarding Exhibit 21 , the year 1928 shows a runoff figure of 6.660 438. Please answer the following: Is this figure in acre-feet? RESPONSE TO REQUEST NO. 298: Yes. IDAHO POWER COMPANY'S RESPONSE TO IDAHO IRRIGATION PUMPERS ASSOCIATION'S SECOND DATA REQUEST Page The response to this request was prepared by Gregory W. Said, Manager Revenue Requirement, Idaho Power Company, in consultation with Barton L. Kline Senior Attorney, Idaho Power Company. Why is this figure less than the figure of 6 966 928 for 1928 found on Exhibit 35 in Case No. IPC-03-13? RESPONSE TO REQUEST NO. 29b: Please refer to Idaho Power Company s Response to the Second Production Request of the Commission Staff Request No. 19. The response to this request was prepared by Gregory W. Said , Manager Revenue Requirement, Idaho Power Company, in consultation with Barton L. Kline Senior Attorney, Idaho Power Company. What is the source of information or method is used to calculate the runoff figures in this case and contrast that with the source of information or method used in Case No. IPC-03-13? RESPONSE TO REQUEST NO. 29c: Please refer to Idaho Power Company s Response to the Second Production Request of the Commission Staff Request No. 19. The response to this request was prepared by Gregory W. Said , Manager Revenue Requirement , Idaho Power Company, in consultation with Barton L. Kline Senior Attorney, Idaho Power Company. REQUEST NO. 30: Exhibit 22 lists for the 1993 test year a "Normalized Power Supply expense" of $48 039 000, a "Normalized CSPP" expense of $34 114 160 and Normalized System Firm Load" of 13 952 283 MWh. Please reconcile these IDAHO POWER COMPANY'S RESPONSE TO IDAHO IRRIGATION PUMPERS ASSOCIATION'S SECOND DATA REQUEST Page 2 amounts with the figures from Case IPC-93-08 of $18 733 020 power supply expense , $32 031 700 CSPP expense, and sales of 10 171 546 MWH. RESPONSE TO REQUEST NO. 30: The power supply expense and CSPP expense values (included in the question) which the Irrigators state were from the IPC-93-08 PCA case were values corresponding to a July 1991 through June 1992 test year that was utilized to establish the initial PCA regression formula. A 1993 test year was first introduced in Case No. IPC-94-5 (a general revenue requirement proceeding) and was further utilized in Case No. IPC-95-5 (the Twin Falls case). The normalized CSPP value of $34 114 160 was established in Case No. I PC-94-5 and was not changed in Case No. IPC-95-5. Test year 1993 normalized power supply expenses were established in Case No. IPC-94-, but were modified to $48 039 000 in Case No. IPC-95- The sales value of 10 171 546 MWH (included in the question) that the Irrigators state is from the IPC-93-08 PCA case is an Idaho jurisdictional sales number based upon the July 1991 through June 1992 test year used to establish the initial PCA regression formula. The 13 952 283 MWH value contained in Exhibit 22 is a system value rather than an Idaho jurisdictional value , and is a load value as opposed to a sales value. It is the system firm load number utilized in Case No. IPC-95- The response to this request was prepared by Gregory W. Said , Manager Revenue Requirement , Idaho Power Company, in consultation with Barton L. Kline Senior Attorney, Idaho Power Company. IDAHO POWER COMPANY'S RESPONSE TO IDAHO IRRIGATION PUMPERS ASSOCIATION'S SECOND DATA REQUEST Page 3 REQUEST NO. 31: Regarding pages 5 and 6 of Ms. Brilz workpapers there is listed the net investment for the various substations. Please answer the following: There are two different entries for the Don Substation with different values for each (one on page 5 and one on page 6). What is the difference between these two entries? RESPONSE TO REQUEST NO. 31a: The entry for the Don Substation on page 5 details the Contribution in Aid of Construction (CIAC) received from Astaris (previously known as FMC) for investment in the Don Substation. The entry for the Don Substation on page 6 details the CIAC received from Simplot for investment in the Don Substation. 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. Other than Simplot, what load does the Don Substation serve? RESPONSE TO REQUEST NO. 31 b: The Don Substation directly serves Simplot and Astaris. The Don Substation also operates as part of the integrated transmission system providing service to the entire Eastern Idaho area. 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. IDAHO POWER COMPANY'S RESPONSE TO IDAHO IRRIGATION PUMPERS ASSOCIATION'S SECOND DATA REQUEST Page 4 What is the capacity of the Don Substation, what percentage of this station capacity does Simplot use, what percentage of this station capacity does Astaris use, and what percentage of this station capacity is used by other customers? RESPONSE TO REQUEST 31c: Don Substation operates as part of the integrated transmission system providing service to the Eastern Idaho area customers. It is assumed the term "capacity" is intended to mean transformer capacity in Don Substation. The transformer capacity in Don Substation is 423.5 MV A. Simplot uses approximately 6% of the transformer capacity and Astaris uses approximately 1 % of the transformer capacity. 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. Why isn t this plant associated with the Don Substation directly assigned or at least a large portion ofit to Simplot and/or Astaris? RESPONSE TO REQUEST 31d: A portion of the Don Substation is directly assigned to Simplot. The amount of substation investment directly assigned to Simplot can be found on Exhibit No. 37 , page 44 , column M , line 24. Astaris is no longer a special contract customer. Consequently, no direct assignment of substation investment is made to Astaris. 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. IDAHO POWER COMPANY'S RESPONSE TO IDAHO IRRIGATION PUMPERS ASSOCIATION'S SECOND DATA REQUEST Page 5 Please supply supporting data that shows how the direct assignment of $1 343 736 of substation costs to Simplot was developed (page 2)? RESPONSE TO REQUEST NO. 31 e: The supporting data can be found on page 12 of Ms. Brilz s workpapers. 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. Regarding the DRAM and Micron Substations, what load other than the Micron load is served by these substations? RESPONSE TO REQUEST NO. 31f Both the DRAM and the Micron Substations are an integrated part of the area transmission system which provides service to all customers in the area. 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. Why isn t the entire cost of these substations directly assigned to Micron? RESPONSE TO REQUEST NO. 31g: A portion of both the DRAM and Micron Substations are integrated into the area transmission system which provides service to all customers in the area. This portion of the substation investment is not directly assigned to Micron. IDAHO POWER COMPANY'S RESPONSE TO IDAHO IRRIGATION PUMPERS ASSOCIATION'S SECOND DATA REQUEST Page 6 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. Please supply supporting data that shows how the direct of assignment of $14 599 997 of substation costs to Micron was developed (page 2)? RESPONSE TO REQUEST NO. 31 h: The supporting data can be found on pages 4 and 11 of Ms. Brilz s workpapers. 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. For each of the substations listed on pages 5 and 6 please provide the relative percentage of these substations that is serving the specific "customer class listed in the far right-hand column. RESPONSE TO REQUEST NO. 31 i: The relative percentage of the substation serving the specific "customer class" is approximated by the ratio of 12 months of energy use by the specific customer class compared to the same 12 months energy use by all customer classes served through the distribution system supplied by each substation, ignoring any parts of other local or regional area load served through the substation as part of the transmission system. As some customers may transfer between customer classes , new accounts may be added during the period , accounts may be closed during the period , and some information may not be complete in associating specific customer accounts to distribution transformers, the relative IDAHO POWER COMPANY'S RESPONSE TO IDAHO IRRIGATION PUMPERS ASSOCIATION'S SECOND DATA REQUEST Page 7 percentages may vary or have changed over time. However, the results attached with this response are the best approximation we currently have available. 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. 32: Regarding page 13 of the workpapers of Ms. Brilz the line for the Primary component of the "Ration Component" includes figures such as 161 711 547 , etc. For each of these figures , please break out the proportion that is only Primary based and the portion that supports both Primary and Secondary. RESPONSE TO REQUEST NO. 32: Property units in distribution accounts are designated as primary or secondary based on the purpose for which they are used. The identification occurs at the time of installation and is based on the information included on the actual work orders prepared as part of the Company facilities installation process. In general, distribution equipment located between substations and the transformers that ultimately serve customers is considered primary. Distribution equipment used to directly provide service to customers is considered secondary . Poles, towers, or fixtures (recorded in FERC Account 364) that support only primary lines are classified as primary. Poles, towers, or fixtures that support only secondary lines are classified as secondary. Poles, towers , or fixtures that support both primary and secondary lines are classified as primary since the poles, towers, or fixtures need to be constructed to the standards necessary to support primary lines. A breakout of the proportion of the Company s investment in poles , towers , and fixtures that support IDAHO POWER COMPANY'S RESPONSE TO IDAHO IRRIGATION PUMPERS ASSOCIATION'S SECOND DATA REQUEST Page 8 only primary lines versus those that support both primary and secondary lines is not available. The primary component amounts under the "Ratio Component" section on page 13 of Ms. Brilz s workpapers for FERC Accounts 365 , 366, and 367 are the proportions that are primary only. 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. REQUEST NO. 33: Regarding page 22 of the workpapers of Ms. Brilz the metering report for the State of Idaho has a cost per meter for Schedule 24 customers of $309 per meter and for Schedule 25 of $304 per meter. Please explain how the figures on this page are derived and why time of use meters would be cheaper than standard (presumably vintaged) meters. RESPONSE TO REQUEST NO. 33: On an annual basis, the average vintage year investment per meter property unit is determined. The average vintage year investment (by property unit) is then applied to the actual number of meters for each particular property unit and each customer class to derive the total investment in each type of meter for each customer class. The investment across all meter types is then summarized by customer class and reported on the Cost of Metering Report. The total meter investment for any particular customer class will reflect the total quantity of meters utilized by that class as well as the variation in the types and costs of meters utilized by that class. The Schedule 24 customer class has a higher proportion of larger customers who require a higher-cost transformer rated meter IDAHO POWER COMPANY'S RESPONSE TO IDAHO IRRIGATION PUMPERS ASSOCIATION'S SECOND DATA REQUEST Page 9 whereas most customers taking service under Schedule 25 utilize a lower-cost self- contained meter. In addition, approximately 400 AMR meters are installed for use by customers taking service under Schedule 24. These meters cost about $200 more than the typical meter installed for irrigation service. In 2002 , there were 219 metered service points enrolled in the Irrigation Time-of-Use Pilot Program. During 2005 , only 126 metered service points were enrolled in the Pilot. Therefore , 93 of the TOU meters which cost approximately $30 more than the typical irrigation meter, are now associated with the Schedule 24 customer class. Each of these factors affects the total meter investment attributed to each customer class. 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. DATED at Boise, Idaho, this 6th day of January, 2006. BARTO L.
