ZZ. ENERGY RESOURCE RECOVERY ACCOUNT
1. Purpose
The Energy Resource Recovery Account (ERRA) is established pursuant to
D.02-10-062. The purpose of the ERRA is to record SCEs: (1) ERRA Revenue, (2)
Utility Retained Generation (URG) fuel costs, and (3) purchased power-related
expenses, excluding California Department of Water Resources DWR power
contract expenses. Electric Energy Transaction Administration (EETA) costs should
be excluded from the ERRA consistent with D.02-12-074. Pursuant to D.04-01-048,
SCE is authorized to record the above-market cost of Qualifying Facilities and
Purchase Agreements in the ERRA. Pursuant to Resolution E-4112, SCE
established the SO
2
Credit-Account (SO2CSA) to track the revenue and cost
associated with the sale and purchase of both Mohave and non-Mohave SO
2

allowances.

Total Authorized Fuel and Purchased Power Revenue Requirement:

Total Authorized Fuel and Purchased Power Revenue Requirement shall be
the current Commission adopted revenue requirement in rate levels
associated with SCE fuel and purchased power expenses.

Total Authorized SCE Generation Revenue Requirement shall be the current
Commission adopted revenue requirement in rate levels associated with
SCEs base generation, fuel and purchased power, and any other
commission adopted generation costs (excluding SCEs allocation of DWRs
revenue requirement).
c.
ERRA Billed Revenues:

Shall be determined each month as follows:

(A / B) * C
Where: A = Total Authorized Fuel and Purchased Power Revenue
Requirement

B = Total Authorized SCE Generation Revenue Requirement

C = Total recorded billed Generation revenues adjusted to remove
the impact of 20/20 Rebate Program, the Residential
Generation Tier 1 and Tier 2 revenue shortfall/surplus that
occurs as the result of implementing Resolution E-3897, and
the 2006 Residential revenue deferral that will take place as the
result of deferring the Residential rate increase authorized in
D.06-06-067 until February 14, 2007
.



d.
ERRA Unbilled Revenues:

Unbilled Revenues are accrued (earned revenue for financial statement
purposes) ERRA revenues associated with electric customer kWh usage that
has not yet been billed by SCE. (ERRA Unbilled Revenues will be allocated
using the same percentage as used to determine the ERRA Billed Revenue).

including DWR revenue billed to Direct Access Customers through the DA
Cost Responsibility Surcharge.

j. Interest
Rate:

The Interest Rate applicable to undercollections shall be the most recent
monthly interest rate on Commercial Paper (prime, three months), published
in the Federal Reserve Statistical Release, H-15 (index) plus a premium of
three-fourths the spread between the index and SCEs actual cost of short-
term financing until that spread is 50 basis points or less or until SCE is able
to issue commercial paper, which ever occurs first. This premium on the
index shall not be precedent setting. At that time the interest rate for
undercollections shall revert to the index rate. The interest rate for
overcollections shall be set at the index rate. Should publication of the
interest rate on Commercial Paper (prime, three months) be discontinued,
interest shall so accrue at the rate of the most recent annual interest rate on
Commercial Paper that most closely approximates the rate that was
discontinued, and which is published in the Federal Reserve Statistical
Release H-15, or its successor publication.
