On May 1, 2020, Dominion Energy filed its 15-year, long-term integrated resource plan (IRP) for Virginia which includes three separate models to increase solar, wind, and energy storage capacity.[1][2] According to the IRP, the utility has already begun to transition its generation fleet away from fossil fuels; over the past decade more than 2.2 GW of coal, oil, and gas-fired generation has been retired. Currently the utility has 396 MW of solar, 1.8 GW of energy storage, and 12 MW of offshore wind under construction or in operation. Its latest IRP would add between 6.7 GW and 18.8 GW of solar, up to 2.7 GW of storage and up to 5.1 GW of offshore wind in the next 15 years. It would also add natural gas resources and potentially keep more gas-fired generation on the system to address system reliability.

In April 2020, Virginia passed the Virginia Clean Economy Act (VCEA) which set a goal of 100% clean energy resources by 2045 and requires the addition of up to 5.2 GW of offshore wind.[3] Three of the four scenarios Dominion proposed take into account the VCEA and other legislation passed in spring 2020, while one presents a “low cost” plan.
