Dominion Energy Inc. will permanently shut down more than 2,000 MW of oil-, gas- and coal-fired capacity including 10 units that were idled in 2018.

Paul Koonce, president and CEO of the Dominion Power Generation Group, said March 25 that the company is "going to retire" the less efficient coal, oil and natural gas units it placed into "cold reserve" in early 2018. Dominion also announced the planned closure of the 790-MW Possum Point 5 oil-fired unit.

"That will be part of how we see ourselves lessening our dependence on steam-based generation," Koonce told analysts at the company's 2019 investor day in New York.

Dominion spokesman Dan Genest said 10 units representing 1,292 MW of capacity will be retired by the end of March.

This includes Possum Point units 3 and 4 and Bremo Bluff units 3 and 4, which all were converted from coal to natural gas within the last decade.

The 267-MW Bellemeade Power Station and 138-MW Mecklenburg Cogeneration Facility also will be retired, along with coal-fired units 3 and 4 at the 1,301-MW Chesterfield coal plant and the 83-MW Pittsylvania Power Station.

The company said the units placed in cold reserve account for less than 1% of its generation.

Possum Point 5 will be retired in 2021, Genest said.

Koonce added that the company sees the potential for more retirements over the next decade as the company adds solar capacity.
