District of Columbia Standard Offer Service (SOS) RFP

Potomac Electric Power Company (Pepco), under the rules established by the District of Columbia Public Service Commission (Commission) per Order No. 23156, is conducting its twenty-third year Request for Proposals (RFP) process for Standard Offer Service (SOS). This solicitation seeks full-requirements wholesale electric power supply for the contract period beginning June 1, 2027. The RFP is a competitive procurement designed to secure reliable and cost-effective electricity supply for Pepco's DC customers.

The RFP targets three distinct service types: Residential, Small Commercial, and Large Commercial customer classes. Each class contains specific retail rate schedules as detailed in the RFP documents. The corresponding Peak Load Contributions (PLC) being solicited are 131 MW for Residential, 9 MW for Small Commercial, and 214 MW for Large Commercial, totaling 354 MW. Bidding is structured in tranches, with up to three rounds planned to fully procure the load. Residential and Small Commercial load is solicited under 36-month supply contracts representing approximately 26% of that combined load, while Large Commercial load is solicited under 12-month contracts for 100% of that service type. The load is divided into bid blocks of approximately 50 MW each for bidding purposes.

Prospective suppliers must submit an Expression of Interest form to gain access to the Ariba website containing the full RFP documentation. Bids are submitted electronically using specific Bid Form Spreadsheets for each tranche, service type, and contract term. All shaded cells within the spreadsheets must be completed; blank cells result in a non-conforming bid and elimination from consideration. Pricing must be represented with exactly two decimal places to prevent rounding discrepancies in the evaluation.

Evaluation is based on reducing all pricing components to a single Discounted Average Term Price for comparison. Contract blocks are awarded to the lowest conforming bidders until the tranche targets are filled. Selected suppliers are obligated to provide a percentage of Pepco's actual hourly retail load for their awarded service type, ensuring supply follows real-time demand.
