NOTICE OF SOUTHERN CALIFORNIA EDISON COMPANY’S SUPPLEMENTAL FILING FORSUMMER 2014 INTERIM RESIDENTIAL RATE REFORM (R.12-06-013)

December 2013 Page 6 of 8

SUMMARYOn November 22, 2013, Southern California Edison Company (SCE) filed a request with the California Public Utilities Commission (CPUC), as required by Rulemaking R.12-06-013, for changes to rates for residential customers effective by the summer of 2014, as described below. SCE is proposing to better align rates with the actual costs of providing electric service to customers and to simplify rate plans.

ABOUT THE PROPOSALOn October 7, 2013 Governor Jerry Brown signed Assembly Bill 327 (AB 327) into law. This new law authorizes the CPUC to consider several changes to California’s electricity rate structure and renewable energy policies to better serve customers. SCE is requesting approval to begin the process of reforming its residential electric rate structure consistent with AB 327 by the summer of 2014. SCE’s filing is part of the CPUC’s efforts to explore improved residential rate design structures, which is currently being examined in R.12-06-013.

This proposed request will not change the amount of total revenues collected by SCE, which are determined in other proceedings. In its request, SCE proposes to redefine the range of usage and reduce the number of rate tiers from four tiers to three tiers on the standard residential electric rate plan (Schedule D). SCE does not propose any change to current baseline allowances, which are billed at the Tier 1 rate. However, SCE proposes to create a new Tier 2, which will combine usage in Tiers 2 and 3 as currently defined, for usage from 101% to 200% of the baseline allowance. The Tier 3 rate would apply to all usage in excess of 200% of the baseline allowance, which is currently defined as Tier 4.

If SCE’s proposal is adopted, residential customers would see bill increases or bill decreases depending upon their monthly usage levels, their rate plan, and other changes in SCE’s authorized revenues.

SCE proposes to provide a 30% energy rate discount to customers on the California Alternate Rates for Energy (CARE) program served on the standard CARE rate plan (Schedule D-CARE). Under SCE’s proposed changes, CARE customers would continue to receive substantial overall savings compared to bills paid by non-CARE customers within the range of discounts required by law. Currently, CARE customers receive an average overall discount of 31% on their bills. With SCE’s proposal to reduce the discount to 30%, a CARE customer using 600 kWhs a month will see an increase of $4, from the current $70 a month to $74 a month.

HOW WILL SCE’s PROPOSAL AFFECT ME?Most customers receive bundled electric service from SCE, meaning that we provide electric generation, transmission and distribution service. The tables below show current and projected rates and monthly bill impacts for non-CARE bundled customers and at various usage levels.
