Issue 4: Should the Commission alter the "incentive mechanisms"

pending I.01-08-029 and should adjust the customer satisfaction

DECISION GRANTING PETITION TO MODIFY
SOUTHERN CALIFORNIA EDISON COMPANY'S
PERFORMANCE BASED RATEMAKING MECHANISM
We grant in part the Expedited Petition for Modification of Decision (D.) 96-09-092 (Petition) filed by Southern California Edison Company (Edison) that seeks to extend and modify Edison's Performance Based Ratemaking (PBR) mechanism until superseded by its 2003 General Rate Case (GRC).1 In particular, we adopt a methodology for setting a revenue requirement for calendar year 2002 and for the period from June 14, 2001 to December 31, 2001. The adopted methodology increases Edison's distribution revenue requirement by the change in the Consumer Price Index (CPI) minus a productivity factor, X. In addition, the methodology increases Edison's revenue requirement to account for the additional costs produced by expanding the distribution network to connect new customers. Further, pursuant to Pub. Util. Code § 739.10,2 we establish a balancing account to ensure that errors in estimates of electricity sales do not result in material over- or under-collections of the revenues authorized by the adopted methodology.
In addition, we examine other aspects of the PBR to determine if modifications are required. We do not change the financial "trigger mechanism," a process for changing Edison's authorized Return on Equity (ROE). We suspend the incentive program concerning worker safety because it is not needed to promote worker safety. In addition, we update the performance benchmark for the customer satisfaction and outage frequency programs to reflect recent trends in Edison's performance. We leave unchanged the incentive program concerning the duration of outages. Finally, we decline to supplement the revenues earmarked for conservation programs in this proceeding.
1 Edison originally filed its motion in NOI 00-09-008, but served it on the parties to Edison's last GRC Application 93-12-025/Investigation (I.) 94-02-002. The Commission transferred the motion to the GRC docket. 2 All subsequent statutory references are to the Public Utilities Code.
