Overview
The Retail Electric Competition and Consumer Protection Act of 1999 requires the Public Service Commission of the District of Columbia (DCPSC) to report to the D.C. Council every two years on the overall fuel mix information for electricity sold in the District. This comprehensive report provides crucial insights into the sources of electricity powering the District and tracks progress toward renewable energy goals.
The report examines the fuel mix composition, renewable energy achievements, and emissions data, helping District residents and policymakers understand the environmental impact of electricity consumption and make informed decisions about energy choices through DC Power Connect, the official retail choice site for the District.
This biennial report fulfills multiple legislative requirements, including tracking renewable energy portfolio standard (RPS) progress and emissions disclosures, while addressing the District's broader climate commitments to achieve carbon neutrality by 2045.
2025 Biennial Report on Fuel Mix
The District continues to achieve meaningful progress on its renewable energy goals and remains a recognized leading jurisdiction within the larger PJM Interconnection regional grid, which includes 13 states and the District. For calendar year 2024, based on the specific fuel mix reports provided by the retail electricity suppliers (including Pepco's Standard Offer Service), the approximate fuel mix for the District appears to reflect an overall renewable energy component of nearly 23% of the total energy sold in the District, in contrast to the renewable PJM System Mix of roughly 8.1%.
This higher use of renewable resources, relative to the overall PJM System Mix, helped contribute to an 11% reduction in the carbon dioxide emissions associated with the sale of electricity in the District. The District continues to maintain a robust and legislatively mandated RPS program, which serves as the controlling indicator for tracking renewable energy performance in the District.
Key Highlights
- Renewable Energy Leadership: The District's 23% renewable share significantly exceeds the regional PJM average of 8.1%
