WASHINGTON BOISE, IDAHO 83702-5983 Attorney for the Commission Staff BEFORE THE IDAHO PUBLIC UTILITIES COMMISSION IN THE MATTER OF THE REVISION AND UPDATED CALCULATION OF THE AVOIDED COST RATES FOR A VISTA CORPORATION DBA A VISTA UTILITIES, FOR IDAHO POWER) COMPANY AND FOR P ACIFICORP DBA UTAH) POWER AND LIGHT COMPANY. CASE NO. A VU-O4- IPC-O4- P A C- E-O4- COMMENTS OF THE COMMISSION STAFF COMES NOW the Staff of the Idaho Public Utilities Commission, by and through its Attorney of record, Scott Woodbury, Deputy Attorney General, and in response to Order No. 29628, Notice of Avoided Cost Recalculations, Notice of Modified Procedure and Notice of Comment/Protest Deadline issued on November 4 2004 in Case Nos. A VU-04-, IPC-04- and PAC-04-, submits the following comments. BACKGROUND Pursuant to the Public Utility Regulatory Policies Act of 1978 (PURP A) and the implementing regulations of the Federal Energy Regulatory Commission (FERC), the Idaho Public Utilities Commission (Commission) has approved a methodology for calculation of the avoided cost rates paid to PURP A qualifYing cogeneration and small power production facilities (QFs) by Idaho STAFF COMMENTS NOVEMBER 23 , 2004 Power Company, A vista Corporation and PacifiCorp. Avoided cost rates are the purchase price paid to QFs for purchases of QF capacity and energy. Three recent events have triggered consideration of computation of new PURP A avoided cost rates, i., the conclusion of general rate cases for Idaho Power and A vista, and the release of a new natural gas price forecast by the Northwest Power and Conservation Council (NPCC) 1 The conclusion of a general rate case affects avoided cost rates because cost of capital figures are used in avoided cost computations in accordance with the approved methodology. The Commission, in Order No. 29628 , found that the appropriate time to incorporate new cost of capital figures is following a general rate case. A final Order in Idaho Power s general rate case was issued on May , 2004 (Order No. 29505) and a Reconsideration Order was issued on September 28 , 2004 (Order No. 29601). A final Order in Avista s general rate case was issued on October 8, 2004 (Order No. 29602). On September 24 2004, the Northwest Power and Conservation Council released a new natural gas price forecast. Because the new forecast was released at about the same time as the Idaho Power and A vista rate cases were concluded, the Commission has found that both the new cost of capital figures and the new natural gas prices should be incorporated in the computation of new avoided cost rates. Reference Order No. 29628. The Commission is not proposing to revise the cost of capital figures used for PacifiCorp. The practice of updating avoided cost rates due to new fuel price forecasts can be traced to Commission Order No. 29124, Case No. GNR-02-1. In that Order, the Commission adopted a fuel price forecast from the draft Fifth Northwest Conservation and Electric Power Plan, April 25 2002 of the Northwest Power Planning Council (NWPPC) as a reasonable method for calculating a starting gas price in the avoided cost methodology. In doing so , the Commission expressed confidence in the source and the use of a medium forecast, which it continues to believe is reasonable. In Order No. 29124, the Commission stated that "natural gas prices can be updated when a new NWPPC forecast becomes available." The Commission has since approved updated gas prices based on an April 22, 2003 NWPPC forecast in December 2003. Order No. 29391. Formerly the Northwest Power Planning Council (NWPPC). STAFF COMMENTS NOVEMBER 23, 2004 STAFF REVIEW Staff has computed new rates using the Council's September 24, 2004 natural gas price forecast and Idaho Power s and Avista s revised costs of capital. The new rates are approximately 5 mills/kWh higher than the rates currently in effect for all three utilities. Computation of the rates is a ministerial task done in accordance with prior Commission orders; nevertheless, Staff s computation of the rates has been reviewed by the utilities to insure mathematical accuracy. In its review of the draft rate computations, Idaho Power pointed out to Staff that an updated general inflation rate of 2.9% had been used in the spreadsheet that calculates the initial gas price and the gas price escalation rate. Idaho Power contends that updating the general inflation rate is outside the scope of the fuel price and cost of capital changes outlined by the Commission in establishing these dockets. Moreover, the general inflation rate is also one of many other variables used in the avoided cost spreadsheet, yet none of those other variables are being updated in these proceedings. Staff agrees with Idaho Power that the general inflation rate should not have been changed. Staff has re-computed the avoided cost rates using a general inflation rate of2.7%, which was used previously and as established in Order No. 29124. A copy of the re-computed avoided cost rates is attached for each of the three utilities. No other errors or corrections were identified or recommended by any of the utilities following their reviews. RECOMMENDATION Staff recommends that the Commission adopt the avoided cost rates that are attached to these comments. These rates reflect incorporation of the NPCC's September 24, 2004 natural gas price forecast, in addition to the newly adopted cost of capital figures for Idaho Power and A vista as determined in their recently concluded rate cases.
