STATE OF CALIFORNIA ARNOLD SCHWARZENEGGER, Governor PUBLIC UTILITIES COMMISSION SAN FRANCISCO, CA 94102-3298 September 22, 2008 Advice Letter 2224-E Akbar Jazayeri Vice President, Regulatory Operations Southern California Edison Company P O Box 800 Rosemead, CA 91770 Subject: Modification to CCA Notification and Open Season Requirements and CCA Liability for Forecasting Errors Dear Mr. Jazayeri: Advice Letter 2224-E is effective April 9, 2008 Sincerely, Kenneth Lewis, Acting Director Energy Division

Akbar Jazayeri Vice President of Regulatory Operations March 10, 2008 ADVICE 2224-E (U 338-E) PUBLIC UTILITIES COMMISSION OF THE STATE OF CALIFORNIA ENERGY DIVISION SUBJECT: Modification to CCA Notification and Open Season Requirements and CCA Liability for Forecasting Errors In compliance with California Public Utilities Commission (Commission) Decision (D.) 08-02-013, Southern California Edison Company (SCE) hereby submits for filing the following changes to its tariff schedules. The revised tariff sheets are listed on Attachment A and are attached hereto. PURPOSE As directed in D.08-02-013, SCE submits tariff changes to: 1) remove the requirement that customer notifications by Community Choice Aggregators (CCAs) be reviewed and approved by the Commission s Public Advisor; 2) modify the Commencement Date provisions of SCE s Open Season tariff (i.e. Rule 23.2); and 3) remove any references to a requirement that a CCA provide evidence of insurance, self-insurance, or a bond for forecasting errors. BACKGROUND Assembly Bill (AB) 117 enacted in 2002 authorizes cities and counties located within the service territory of an investor owned utility (IOU) the option of procuring power on behalf of citizens and businesses located within their municipal boundaries. This is known as Community Choice Aggregation. The Commission initiated Rulemaking (R.) 03-10-003 to implement AB 117. D.05-12-041, as modified by D.06-02-006, had adopted certain procedures and rules to facilitate the creation and implementation of CCAs according to the provisions of AB 117. P.O. Box 800 2244 Walnut Grove Ave. Rosemead, California 91770 (626) 302-3630 Fax (626) 302-4829

ADVICE 2224-E (U 338-E) - 2 - March 10, 2008 Following D.06-02-006, the Commission staff became aware of differing interpretations of the Commission orders dealing with Community Choice Aggregation. One dealt with whether the CCAs were required to submit the customer notifications required before the commencement of Community Choice Aggregation to the Commission s Public Advisor for review and approval. The second dealt with whether a CCA, which had provided a binding notice of intent (BNI), could modify its service commencement date once or multiple times. The assigned Administrative Law Judge (ALJ) issued a ruling on August 3, 2007, proposing changes to the IOUs tariffs to ensure consistency with Commission policy. Comments were received from San Joaquin Valley Power Authority (SJVPA) and jointly by San Diego Gas & Electric Company (SG&E), SCE, and Pacific Gas and Electric Company (PG&E) (together as Joint Utilities ). Subsequently, due to conflicting provisions within D.05-12-041, the assigned ALJ issued a ruling on December 4, 2007, proposing the elimination of references to bond, insurance, and self-insurance for forecasting errors. Comments were received from City and County of San Francisco, SJVPA, SCE, PG&E, and Local Sustainable Energy Coalition. The Commission, in D.08-02-013 adopted February 28, 2008, ordered SCE, within ten days of the effective date of the order, to revise its tariffs to reflect the modifications required by the Decision. The SCE tariffs affected by D.08-02-013 are: Rule 23 Community Choice Aggregation Rule 23.2 Community Choice Aggregation Open Season PROPOSED CHANGES The following changes to SCE s attached tariffs are made pursuant to D.08-02-013: 1. Removal of tariff provision requiring CCAs to submit customer notices to the Commission for review or approval. 2. Requiring that a new commencement date must not be more than three months after the date specified in the original BNI. 3. Requiring updates to a commencement date later than that stated in the original BNI to be made during SCE s Open Season process at least a year in advance of the original commencement date specified in the BNI. 4. Adding that a BNI date can be changed, at any time, to an earlier date. 5. Removing a provision that CCAs must satisfy credit worthiness standards related to forecasting. No cost information is required for this advice filing.

CCA CUSTOMER NOTIFICATION PROCESSES 3. The following additional provisions apply to CCA Customer Notifications: a. The CCA and SCE must mutually agree on the date before the CCA s Customer Notification process can begin. b. CCA Customer Notifications may be sent concurrently with SCE s billing cycles. c. Neither CCAs nor SCE shall use the other party s logo on CCA Customer Notifications or other materials absent express written consent to do so. Neither party shall express nor imply that the other party is affiliated with, is a sponsor of, or endorses their services or other programs. d.

Southern California Edison Revised Cal. PUC Sheet No. 43671-E Rosemead, California (U 338-E) Cancelling Original Cal. PUC Sheet No. 40064-E Rule 23.2 Sheet 3 Community Choice Aggregation Open Season A. CCA Open Season 3. CCA Default on Binding Notice of Intent If the CCA fails to commence service on the date stated in the BNI, or fails to offer service in good faith to all classes of customers stated in that Notice, the CCA will be required to reimburse SCE, upon demonstration in a filing with the Commission, for any incremental costs associated with utility procurement, as described in Section 4 below, resource adequacy penalties, or any other utility costs that are incurred as a result of CCA s default. However, the CCA or its customers will not be subject to any costs incurred by SCE as a result of the CCA's failure to commence service on the date specified if the reason for that non-performance relates to a failure of SCE to meet its commitments to the CCA. 4. Potential Penalties for Deviating From CCA Binding Notice of Intent If the CCA fails to meet its commencement of service date or fails to offer service in good faith to all customer classes stated in the Notice of Intent, SCE shall make a filing with the Commission detailing the incremental costs it incurred as a result of the CCA s failure to fulfill its commitment, for Commission determination of a CCA penalty. The potential penalty to the CCA shall not exceed the would-be transferred load that SCE must continue to serve times the difference between SCE s incremental per kwh cost of acquiring the energy and capacity to serve the load not served by the CCA, and the average cost of SCE s procurement portfolio. This penalty will be calculated on a per day basis for every day that the CCA deviates from the date provided in its BNI. The CCA shall not be entitled to a credit if SCE s per/kwh cost of serving the load not served by the CCA is below the average cost of SCE s procurement portfolio. B. Adjustments to Forecasts In a subsequent Open Season that takes place prior to the CCA commencing service to its customers, the Participating CCA may update its service commencement date, subject to the following conditions: The new commencement date specified in the update BNI must not be more than three (3) months after the date specified in the original BNI. Updates that provide for service through the CCA to commence later than stated in the original BNI must be made during the serving SCE s Open Season process that is held at least a year in advance of the original commencement date in the BNI. A CCA can change its BNI date, at any time, to an earlier date. The change of a BNI to an earlier date does not need to occur during SCE s Open Season process. Any additional costs incurred by the serving utility resulting from this change will be recovered from CCA Service customers and may be allocated to the CCA s CRS.

Southern California Edison Revised Cal. PUC Sheet No. 43672-E** Rosemead, California (U 338-E) Cancelling Original Cal. PUC Sheet No. 40064-E 40065-E Rule 23.2 Sheet 4 Community Choice Aggregation Open Season B. Adjustments to Forecasts : To the extent the CCA and SCE have collaborated on the load forecast as described above, the CCA and SCE shall provide updates to load forecasting data, such as projected rate or service changes, as they become available in advance of the CCA commencement date. This data shall be used solely to refine the collaborative load forecast when necessary. The CEC may also make adjustments to the CCA s Forecast as part of its review of all Load Serving Entity forecasts in the resource adequacy process. The CCA must satisfy SCE credit worthiness standards (which may include provision of adequate security or other assurance) to cover the amount of any potential penalties. As part of the collaborative forecast process, the parties should explore options for mitigating risks associated with forecasts. Such options could include, but are not limited to, agreeing in advance that the party who has excess power will sell power to the party that is short on power. A CCA does not need to provide evidence of insurance, self-insurance or a bond to cover the costs associated with SCE forecasting errors. (L) (L)(N) (N) C. Open Season Phase-In Requirements In the event a CCA elects to phase-in its service and participate in the Open Season, the CCA shall provide in its BNI the schedule by which it intends to phase-in service which shall include the number of customers for each class to be served per the schedule provided. The CCA shall be required to accept the transfer of customers on the dates provided for each phase of its implementation unless it provides an adjustment in a subsequent Open Season period per Section B above. The CCA load forecast shall reflect the incremental changes in CCA load as a result of phasing implementation. All other provisions of the Open Season tariff, including penalties for default and confidentiality, apply to participating CCAs that elect to phase-in implementation. D. CCA Open Season Participation Confidentiality Due to both the binding nature of the CCA commitment to serve customers on a specified date and the potential penalties a CCA may incur if it fails to fulfill its responsibility to prepare for timely commencement of service under this tariff, there is a potential to create market power for suppliers responding to a CCA s solicitation to provide electric power services. In order to prevent the possibility that participation in this tariff may create market power for potential CCA suppliers, all information concerning CCA participation in this tariff will be confidential and, at the option of the CCA, subject to a nondisclosure agreement. Use of information provided by either the CCA or SCE for purposes of load forecasting shall be limited solely for the purposes of the collaborative load forecast. Access to load forecasting information shall be restricted to authorized CCA/SCE staff assigned to prepare the load forecasts for submission to the CEC, and the Commission and CEC staff assigned to review such forecasts.
