III. Affected Accounts
A. PG&E Accounts
PG&E's application included 28 separate accounts; it proposed based on the accounting mechanisms then in place to transfer 21 of those accounts to the TRA7 and 7 accounts to the TCBA.8 The total undercollection PG&E reflected in those accounts as of November 30, 1999, the last date it made the calculation, was $17.4 million.
B. Edison Accounts
Edison sought to transfer 35 accounts in total: 22 to the TRA and 13 to the TCBA. The total undercollection Edison reflected in those accounts as of December 31, 1999, was $48.2 million. The fact that the balance at that time showed an undercollection means that Edison had costs that it desired to recover with an offset to headroom. Subsequently, Edison updated its request in testimony dated February 19, 2002 to exclude balances that were under review by the Commission in other proceedings. This update resulted in Edison changing its request in this proceeding to show that as of September 1, 2001 its accounts reflected that a net overcollection of $55.745 million to be returned to its ratepayers.
7 The TRA was an accounting mechanism designed to facilitate the calculation of the revenues available to offset uneconomic generation costs entered into the TCBA. The TRA was credited with all billed revenues. From that total, the utilities subtracted authorized revenue requirements for distribution, transmission, public benefits programs, and nuclear decommissioning. Then the utility subtracted payments to the CalPX and Independent System Operator (ISO). The remaining balance determined "headroom," the amount available to offset uneconomic generation costs entered into the TCBA. 8 The Commission created the TCBA to track recovery of authorized costs related to uneconomic generation.
