1 Jason M. B. Manuel Director, Pricing & Tariffs P.O. Box 1475 Baltimore, Maryland Fax September 1, 2011 Terry J. Romine, Executive Secretary Public Service Commission of Maryland William Donald Schaefer Tower 6 St. Paul Street, 16 th Floor Baltimore, MD Re: Case Nos. 9056/9064: Supplement 488 to P.S.C. Md. E-6: Rider 29 Rate Mitigation and Recovery Charge Adjustment Dear Ms. Romine: Baltimore Gas and Electric Company ( BGE or Company ) files herewith Supplement 488 to P.S.C. Md. E-6 of the Retail Electric Service Tariff. This Supplement establishes Rider 29 Rate Mitigation and Recovery Charge Adjustment. The purpose of this Rider is to recover from Schedules G and GS Type II customers the Standard Offer Service (SOS) costs above those limited by their total bill increase of 15 percent for the period June 1 August 30, 2008 ( mitigation costs ). Further, this Rider credits to all nonresidential customers the same mitigation costs they were required to incur during this period. Background On May 1, 2008, BGE filed Supplement 414 to P.S.C. Md. E-6 of the Retail Electric Service Tariff (Mail Log # ). This filing included implementation of the expanded definition for Type II customer eligibility pursuant to Order No , issued November 8, In addition, the filing presented revised Type II SOS rates for the June 1 August 31, 2008 billing period, based upon the results of the SOS procurement approved by the Maryland Public Service Commission ( PSC or Commission ) in Order No issued April 25, 2008 in the above-referenced Cases. In a May 16, 2008 Letter Order, the Commission suspended portions of the BGE filing affecting the SOS rates of the New Type II Customers (Schedules G and GS). The Order directed BGE to file substitute tariff pages with SOS rates effective June 1 August 31, 2008 that limited the total average bill increase to 15 percent for the New Type II Customers, compared to the same period in The Order also directed the Company to recover the Estimated Mitigation Costs from all non-residential customers through an adjustment to each rate class distribution charge

2 Terry J. Romine, Executive Secretary September 1, 2011 Page 2 for the June 1 August 31, 2008 rate-effective period. The Estimated Mitigation Costs represented the total revenue difference between the full Type II Market-Priced SOS rates for Schedules G and GS and the mitigated 15 percent bill increase imposed by the Order. The Commission approved BGE s revised tariff in a June 6, 2008 Letter Order. The Maryland Energy Group (MEG) and RG Steel Sparrows Point, LLC objected to the Commission s Orders, contending that the PSC was without authority to cap the SOS rate for new Type II customers and shift a portion of that SOS price to large commercial customers through the non-bypassable distribution charge. The May 16 and June 6, 2008 Letter Orders were subsequently invalidated by the Maryland Court of Appeals on September 17, The case was then remanded to the PSC for further proceedings consistent with the Court s Opinion. On August 19, 2011, representatives from BGE, MEG, RG Steel and PSC Staff met before the Commission. Reversing the original 2008 mitigation and recovery adjustments, the Commission s Bench Order requires: 1. A twelve-month assessment of the mitigation charge for Schedules G and GS Type II customers for the period October 2011 September 2012; 2. A twelve-month credit of the mitigation charge for all non-residential customers for the period October 2011 September 2012; 3. Inclusion of simple interest on the actual mitigated revenue based on the Consumer Price Index (CPI): Urban Consumer All Items ( =100); and 4. A final true-up of the mitigation adjustment at the end of the effective period, the duration to be determined by the PSC based on the magnitude of the trueup amount. The final true-up amount will also reflect the interest accrued during the October 2011 September 2012 credit period based on the actual monthly CPI. Proposed Rider 29 The spreadsheet in Attachment 1 shows the Schedules G and GS Type II adjustments applicable to the SOS rates. In addition, the Attachment includes the offsetting credit of the mitigation costs applied to all non-residential customers. Attachment 2 provides background for the interest calculation based on Consumer Price Indices. The proposed Rider 29 - Rate Mitigation and Recovery Charge Adjustment and associated Tariff pages, Attachment 3, formalize the process as specified in Commission s Bench Order and include the Mitigation Cost Charges and Credits for the October 1, 2011 September 30,

3 Terry J. Romine, Executive Secretary September 1, 2011 Page rate-effective period. The Rider also includes a provision for the final true-up of the mitigation cost adjustment. BGE respectfully requests that this matter be considered at the September 28, 2011 administrative meeting. Respectfully submitted, Jason M. B. Manuel Attachments

17 Baltimore Gas and Electric Company Electric Retail Graduated Rate Discount The Graduated Rate Discount Pilot Program will run for a period of 12 months, from July 1, 2010 through June 2011 billings. The Graduated Rate Discount Pilot Program participants must meet the income eligibility requirements for the Maryland Energy Assistance Program (MEAP) and the Utility Service Protection Program (USPP). The Rider 31 Pilot Program and the Graduated Rate Discount Pilot referenced in the Gas Rider 15 will consist of 3 groups of approximately 300 customers each. One group is required to schedule and complete a Quick Home Energy Checkup (QHEC). Failure to complete the QHEC requirement will result in disenrollment from the pilot. Another group will receive case management services. The Graduated Rate Discount tiers are: Total monthly usage Bill Discount kwh 40% kwh 30% kwh 20% kwh 10% kwh $15 Credit A single discount rate from the table above is applied to the total of the Electric Supply amount and the Electric Distribution Charge amount of a customer s monthly bill. The discount will be combined with any applicable discount earned by customers also participating in the Gas Rider 15 (Graduated Rate Discount) Pilot Program and appear as a separate line item on the customer s bill. Customers having arrearages above $1,000.00, or have not made a payment in the 3 months leading up to the date of enrollment selection, or with a record of theft and/or fraud may not enroll in the program. Customers enrolled in the Electric Rider 32 (CAMP) Pilot that runs concurrently from July 1, 2010 through June 2011 billings cannot also participate in the Graduated Rate Discount Pilot Program. Participants whose service is turned off for fraud, theft or nonpayment will be disenrolled from the pilot program. However, a customer disqualified due to nonpayment may be reinstated into the pilot program with full payment. P.S.C. Md. E-6 (Suppl ) Filed 03/18/201109/01/11 Effective 04/27/201110/01/11
