Chesterfield Power Station Project Summary – Chesterfield Energy Reliability Center (CERC) Project

In January 2018, Dominion Energy (Dominion) stopped using their two coal-fired boilers #3 and #4 and shut them down on March 31, 2019. Coal boilers #5 and #6 were shut down on May 31, 2023. The facility no longer combusts coal in any units.

DEQ received revised Prevention of Significant Deterioration (PSD) permit applications for the CERC project on August 1, 2023 and March 3, 2025. Dominion is seeking a PSD permit for a simple-cycle electrical generating station to be located on the site of the Chesterfield Power Station. Dominion states the purpose of this project is to “support the clean energy transition while optimizing reliability and economics” for their system customers.

Proposed equipment:

Four 250 MW simple-cycle combustion turbines, capable of combusting natural gas, natural gas with hydrogen (up to 10%), and low sulfur #2 distillate fuel oil.
Seven 3,500 kW black start generators firing ULSD.
Several circuit breakers, using SF6 as an insulating gas.
Eight fixed-roof fuel oil storage tanks (one 12 million gallons and seven 3,500 gallons)
Fugitive emissions from piping components

Proposed emissions from facility (tons/year):

PM	PM10	PM25	SO₂	NOx	CO	VOC	Pb	H₂SO₄	CO₂e
81.8	153.9	153.9	27.8	353.3	825.3	162.5	0.063	18.7	2.2 million

Turbine emission include startups and shutdowns (firing both natural gas or fuel oil)

The facility is already considered a major source of HAP emissions. The proposed annual HAP emissions from this project: Maximum individual HAP, 5.07 tons of formaldehyde, Total HAP: 13.5 tons.

Proposed permitting timeline: Permitting Enhancement and Evaluation Platform (PEEP)
