UTiLITIES COMMiSSlO!\ BEFORE THE IDAHO PUBLIC UTILITIES COMMISSION IN THE MATTER OF THE APPLICATION OF ROCKY MOUNTAIN POWER FOR APPROVAL OF CHANGES TO ITS ELECTRIC SERVICE SCHEDULES CASE NO. PAC-07- Rebuttal Testimony of William R. Griffith ROCKY MOUNTAIN POWER CASE NO. PAC-07- October 2007 Please state your name, business address and present position with the Company (also referred to as Rocky Mountain Power). My name is William R. Griffith. My business address is 825 NE Multnomah Street, Suite 2000, Portland, Oregon 97232. My present position is Director Pricing, Cost of Service & Regulatory Operations in the Regulation Department. Are you the same William R. Griffith that previously submitted testimony in this proceeding? Yes. What is the purpose of your rebuttal testimony? The purpose of my rebuttal testimony is to: Offer updated proposed rate spread and rate design exhibits that reflect adjustments to the cost of service study to which the Company has agreed. Address the direct testimony of Mr. Timothy Shurtz concerning customer noticing of the general rate case. Address the direct testimony of Mr. Anthony Yankel testifying for the Idaho Irrigation Pumpers Association (lIP A) concerning rate design for Schedule 10 customers. Address the direct testimony of Mr. Bryan Lanspery for the Idaho Public Utilities Commission Staff concerning rate spread and tariff applicability. Updated Rate Spread and Rate Design Exhibits Please explain Exhibit No. 53. Exhibit No. 53 contains a revised, proposed rate spread along with billing determinants, proposed rate designs for all rate schedules in this case, and Griffith, Di-Reb - Rocky Mountain Power monthly billing comparisons. These reflect the revisions to the cost of service model discussed by Company witness Mr. Mark E. Tucker along with the revenue requirement revisions sponsored by Company witness Mr. Steven R. McDougal. The proposed rate spread is consistent with the Company s proposal in its direct case where the Company proposed uniform percentage increases for residential and irrigation customers along with larger increases for street and area lighting customers and contract customers. No changes are proposed for other rate schedule customers. In a similar manner, the design of proposed rates is consistent with the methodology in the company s direct case, except that the proposed rates now reflect the revised revenue requirement and rate spread in the Company s rebuttal case. Response to Testimony of Mr. Timothy Shurtz Do you agree with Mr. Timothy Shurtz s direct testimony wherein he indicates that Rocky Mountain Power provided "inadequate notice to rate payers No. The Idaho Public Utilities Commission s Rules 102., 102., and 102. specify customer noticing requirements for general rate cases. As indicated by the Commission staff in Mr. Daniel Klein s direct testimony, the company complied with the Idaho Public Utilities Commission s noticing requirements for general rate cases. While Mr. Shurtz might believe that additional requirements should be put in place, the Commission s current requirements have been met by the Company in this docket. Griffith, Di-Reb - 2 Rocky Mountain Power What notice did the Company provide? Rocky Mountain Power issued a press release on the day of filing (Rule 102.04) and sent a bill insert to all Idaho customers (Rule 102.03). The bill insert was distributed to all customers over the course of a billing cycle, and complied with the information requirements specified in Rule 102.01. Rocky Mountain Power also immediately made the filing available at our local offices (Rule 102.01). What is the appropriate forum for determining the adequacy of the Commission s current noticing requirements? As previously noted, the Company complied with the Idaho Public Utilities Commission s noticing requirements for general rate cases in this proceeding. However, if Mr. Shurtz believes additional requirements are needed, the appropriate forum for the review of noticing requirements is a rulemaking proceeding, not a general rate case, because the noticing requirements would apply to all utilities regulated by the Commission, not just Rocky Mountain Power. Response to Testimony of the Idaho Irrigation Pumpers Association Please respond to Mr. Anthony Yankel's recommendation that Rocky Mountain Power offer a time of use rate for irrigation (Schedule 10) customers. Rocky Mountain Power does not believe Mr. Yankel's proposed time of use rate option is complete nor reasonable. Griffith, Di-Reb - 3 Rocky Mountain Power Please explain. The Company has not proposed a time of use rate for irrigation customers in this docket. The proposal filed by IIP A is incomplete. It contains no workpapers or cost basis for the proposed time periods or rate differentials. Moreover, IIP A recommends that "something more like super-peak price be developed" that perfectly overlaps the irrigation load control demand side management program timeframe using "the same 4-days per week.. . and the same 6-hours per day (2:00 m. until 8:00 p. Is it reasonable that liP A's on-peak period proposed in its time of use rate design proposal perfectly overlap the current Irrigation Load Control demand side management program s applicable timeframe? No. We do not believe that IIPA's limited proposal is reasonable. Under IIPA' proposal, customers participating in both the irrigation load control demand side management program and a time of use rate would receive double payment-first the Company would pay customers for their on-peak demand side management efforts through the irrigation load control program and, second, the Company would provide time-of-use tariff discounts to those customers for avoiding on- peak usage. While this would be a good deal for recipients, it is not reasonable to pay customers twice under lIP A's proposal. IIP A does not address this double payment issue. Griffith, Di-Reb - 4 Rocky Mountain Power Would a tariff restriction limiting customers who participate in the irrigation load control demand side management program from participating in the time of use option solve this problem? It might. However, this has not been addressed in IIPA's proposal. What is Rocky Mountain Power s recommendation concerning liP A's time of use proposal? As discussed above, IIP A's proposal is incomplete and, in light of the current load control demand side management program, could result in excessive credits to irrigation customers. The Company recommends lIP A's time of use proposal be rejected. Following this general rate case, would Rocky Mountain Power be willing to work with liP A and other parties to attempt to develop an appropriate time of use rate proposal? Yes. The Company would be willing to work with IIP A and other interested parties on a more thorough analysis to determine the feasibility of such a program. If such a program were developed, it could be introduced at the time the Company filed its next general rate case. Response to Testimony of Commission Staff The direct testimony of Mr. Bryan Lanspery for the Commission staff recommends that the street lighting class s rate be increased so that customers are paying rates equal to their full cost of service. Please compare his recommendation with the Company The company s direct proposal recommended increasing street lighting rates by Griffith, Di-Reb - 5 Rocky Mountain Power approximately two times the overall price change, and made substantial movement toward full cost of service. Staff s recommendation results in an increase of approximately four times the Company s proposal. Does Rocky Mountain Power agree with Staff's proposal? The Company believes that each of the proposals has value and recommends that the Commission weigh the merits of the two approaches. Staff has recommended that the Company clarify the eligibility criteria for Schedule 23, General Service, and Schedule 6, General Service - Large Power. Please comment on Staff's recommendation. Currently, Schedules 23 and 6 are available to all general service customers. Schedule 23 is an energy-only rate that applies to all non-demand metered customers. It also benefits low load factor general service customers including those with demand meters. Schedule 6 has both demand and energy charges; it benefits customers with higher load factors. Along with the presence of a demand charge in Schedule , the Schedule 6 energy charge is about one third the Schedule 23 energy charge. These rate structures have been in place in Idaho for well over two decades and have been optional rates for customers. When a new customer signs up for service, Rocky Mountain Power analyzes the customer s expected usage characteristics and recommends placing the customer on the most advantageous rate for the customer. Customers have been permitted to choose from these two rates based upon their individual circumstances. Griffith, Di-Reb - 6 Rocky Mountain Power Is the Company willing to clarify the eligibility criteria for Schedule 23, General Service, and Schedule 6, General Service - Large Power? Yes. The Company is willing to work with Staff to clarify the eligibility criteria of Schedule 23 and Schedule 6. However, we note that if the current eligibility criteria are revised in such a way that the optional nature of the current rate schedules is eliminated that such a change will likely have rate impacts on customers. We recommend that this eligibility criteria review with Staff occur following the completion of this general rate case and that any revisions be proposed in the Company s next general rate case in order to properly reflect the revenue impacts of any change. Does this conclude your rebuttal testimony? Yes. Griffith, Di-Reb - 7 Rocky Mountain Power . ,- ~J I~ I . .. C~ lUO7QCT26 AM . Case No. PAC-07- . 5fExhibit No. 54 UTI IpAHO PY~, Witness: William. R.
