Statewide

No data-center-specific DC large-load docket or tariff found: the DC Public Service Commission's list of open formal cases has no case title that mentions data centers or large loads. The closest are FC 1183 (an investigation into the effects of the PJM capacity auction, which also set up a PJM Capacity Auction Task Force) and FC 1186 (an investigation into energy affordability in the District). (Public Service Commission of the District of Columbia, Oct. 28, 2026) On Jan. 16, 2026, the DC PSC opened Formal Case No. 1186 (Order No. 22774), an investigation into energy affordability that the Office of the People's Counsel had petitioned for. The announcement names continued load growth as one reason costs are rising but does not mention data centers. (Public Service Commission of the District of Columbia, Jan. 16, 2026) On June 3, 2026, the DC PSC held a legislative-style hearing in Formal Case Nos. 1017, 1183 and 1186 on why the generation portion of residential bills has risen. The Office of the People's Counsel's statement argued that large-load customers such as data centers should pay more of the transmission upgrades built to serve them, and that speculative large-load growth should not leave residential customers carrying the cost. (Public Service Commission of the District of Columbia, June 3, 2026; Office of the People's Counsel for the District of Columbia, May 29, 2026) In a June 25, 2026 letter to the PJM Board, the director of DC's Department of Energy & Environment said the District has no large data centers and no prospect of any, has no large loads to assign new costs to, and has a falling peak load. The letter also said no law or regulation gives the District a way to shift data-center-driven costs elsewhere, and its retail tariffs cannot protect residents from them. (DC Department of Energy & Environment (filed with PJM), June 25, 2026) Not law, but official action: DC Councilmember Charles Allen signed the PJM Legislators Collaborative letter of Nov. 17, 2025, for the District. The letter asked PJM to require new large loads such as data centers to bring their own capacity before PJM buys capacity for them.
