Formal Case No. 1156
Pepco filed a Multi-Year Rate Plan (MRP) Application in May 2019 for approval to increase rates for its electric distribution service in the District. Traditional cost of service rate cases generally reviews costs and investments through a historical approach or partially forecasted test year (which provides for six months historical data and six months of forecasted data). Under this ratemaking paradigm, Pepco has been filing rate cases approximately every two years to recover the costs of their investments in the electric distribution system. The expenses they incurred in litigating each rate case cost ratepayers an average of $3 million each. The DCPSC has long recognized that other forms of regulation may help the District’s meet its aggressive goals regarding greenhouse gas emission reductions, transportation electrification, renewable energy development, grid modernization, and others.
With the Commission’s
grid modernization efforts solidly off the ground in mid-2017, the Commission indicated that it would allow Pepco to include in its next rate case a request for a fully forecasted test year and/or a multiyear rate proposal. The Commission recognized in its decision that the District is in a period of growth and change, with increasing distributed energy resource (DER) deployment. Future rate design questions will need to complement the city’s development of appropriate mechanisms to help us to achieve the goals outline in
PowerPath DC.
The Commission has authority to consider alternative forms of regulation (“AFORs”) under D.C. Code § 34-1504 (d) if the AFOR protects consumers, ensures quality, availability and reliability of regulated services, and is in the public interest of ratepayers and shareholders. In furtherance of the District’s clean energy goals and the Commission’s PowerPath DC objectives, the Commission established the framework for AFORs in the District in December 2019 to explore new tools to achieve those objectives, while also preserving a high standard of energy delivery system reliability and fostering grid modernization.
The Commission is expected to render a decision on Pepco’s MRP soon.
