OPINION ON SOUTHERN CALIFORNIA EDISON COMPANY’S
TEST YEAR 2006 GENERAL RATE INCREASE REQUEST

1. Introduction

1.1 Summary of Decision

This decision addresses the general rate increase request of the Southern California Edison Company (SCE). For test year 2006, SCE is authorized a revenue requirement of $3,749,292,000, which reflects an increase of $333,115,000 or 9.75% over the previously authorized level of $3,416,177,000. The adopted methodology for calculating post-test year revenue requirements results in additional revenue requirement increases of $143,350,000 (3.82%) for post-test year 2007 and $192,573,000 (4.95%) for post-test year 2008. On a general rate case (GRC) revenue basis, when reflecting the effect of increased sales for the test year and post-test years, the revenue increases amount to $273,455,000 (7.87%) for 2006, $73,541,000 (1.93%) for 2007 and $104,055,000 (2.61%) for 2008. On a total system revenue basis, the revenue increases amount to 2.74% for 2006, 0.72% for 2007 and 1.00% for 2008. For test year 2006, this decision also reflects a one-time $139,559,000 reduction for an overcollection in post-retirement benefits other than pensions (PBOPs).[1]

In brief summary, the decision also:

·  Assumes a temporary shutdown of the Mohave Generating Station (Mohave) and reflects costs for this scenario, as forecasted by SCE. All costs will be booked to a twoway balancing account and will be subject to reasonableness review.

·  Orders SCE to establish a Mohave Sulfur Credit SubAccount to accumulate revenues from the sale of any sulfur credits created by the December 31, 2005 Mohave closure. Funds should not be disbursed from this sub-account without specific Commission authorization to do so. The issue of the distribution of revenues accumulated in the Mohave Sulfur Credit Sub-Account will be addressed in a separate proceeding when more information on the future operating status of Mohave is known.

·  Excludes costs for SCE’s proposed Project Development Division in rates, but allows SCE to establish a memorandum account to track those costs that support new generation and are not associated with proposed projects. SCE can then seek to include those supportive costs in future rates.

·  Approves a stipulation regarding Priority 5 maintenance activities. Such activities will continue to be performed on an opportunity basis, while SCE and the Commission’s Consumer Protection and Safety Division work out the details to implement a new maintenance program.

·  Modifies SCE’s Results Sharing request by requiring SCE to credit ratepayers for any difference between the authorized level for Results Sharing and the Recorded level.

·  Adopts The Utility Reform Network’s (TURN) recommendation to recognize, for ratemaking purposes, the regulatory liability associated with plant removal costs that do not meet the definition of an Asset Retirement Obligation.
