Agenda Date: December 29, 1999 Item Number: 2A Docket: UE-991832 Company: Pacific Power & Light Company Staff: Roland C. Martin, Regulatory Consultant, Energy Assigned Rate Case Team Recommendation: Issue a complaint and order suspending the filing in Docket UE-991832 and set the matter for hearing. Discussion: On November 24, 1999, PacifiCorp (dba Pacific Power & Light Company) filed revised tariff sheets applicable to electric service supplied by the Company in Washington. The filing seeks to increase revenues from Washington operations in two phases: First phase (Year 1) requests a general price increase of 8.10 percent or $14.6 million effective January 1, 2000, while Second phase (Year 2) provides for an overall price change of 5.73 percent or $11.2 million effective one year after the Year 1 increase. The total proposed increase in base prices over two years is $25.8 million. In addition to the base price increase, the Company also requests to implement a 1.5 percent ($2.8 million) System Benefits Charge through a tariff rider to fund energy efficiency programs and renewable resource development. The Company’s last general rate increase in Washington was in September 19, 1986. In that proceeding, the Commission granted a revenue increase of $12 million including an attrition allowance of $3.8 million. That increase was based on $327.9 million pro forma rate base and 10.42% overall rate of return and 13.25% return on common equity. In the current filing, the Company is requesting a return on common equity of 11.25% with an overall rate of return of 9.10% to be applied to a pro forma rate base of $609 million. According to the Company, the key factors driving the need for a price increase at this time are rising capital expenditures ($2.9 billion system-wide investment over past 5 years), falling prices ( four rate decreases since 1986), and inflationary pressure on costs (over 60% increase in general price levels since 1986). The Company claims the combination of these factors resulted in its earning a current normalized rate of return of 6.5 percent in Washington. In addition to the implementation of a System Benefits Charge in this filing, the Company is also proposing to reduce subsidization across customer classes, and to modify certain Company rules regarding provision of electric service. Docket UE-991832 December 29, 1999 Page 2 The company serves approximately 120,000 retail electric customers in five counties in Washington (Yakima, Walla Walla, Kittitas, Garfield, and Columbia), and approximately 1.45 million retail customers in the States of Oregon, Utah, Wyoming, Idaho, California, and Washington. Summary of Rate Increase Impacts: The following portrays the magnitude of proposed revenue increases for the major customer classes: Year 1 Increase (Inclusive of System Benefits Charge) Customer Class: Annual Percent Revenue Change Residential $ 9,126,000 12.00% Commercial & Industrial 8,239,000 7.97% Public Street Lighting 50,000 4.00% Total $17,415,000 9.64% Year 2 Increase (Inclusive of System Benefits Charge) Customer Class: Annual Percent Revenue Change Residential $ 6,246,000 7.33% Commercial & Industrial 4,925,000 4.41% Public Street Lighting 26,000 2.00% Total $17,415,000 5.65% In order to determine whether the proposed tariff revisions are fair, just, reasonable, and sufficient, Staff recommends the Commission issue a complaint and order suspending the filing in Docket UE-991832 and set the matter for hearing.
