Power bills in Loudoun County
Most of the county is served by Dominion Energy.
Deferred fuel cost recovery (docket PUR-2026-00078) is pending; Dominion Energy says it would add about $7 to $9 to a typical monthly bill. Data center cost allocation and transmission rider (docket PUR-2026-00056) adds about $0.94 a month to a typical bill, decided August 1, 2026. 2025 biennial review base rate increase (docket PUR-2025-00058) adds about $11.24 a month to a typical bill from January 2026.
Dominion's fuel and purchased power costs ran roughly a billion dollars past what bills collected. Recovering it directly would add about 21.79 dollars a month to a 1,000 kWh bill; Dominion proposes spreading it over 7 to 10 years with bonds instead, about 8 dollars a month. The hearing was August 12, 2026 and a decision is due by late September 2026.
