Dominion Virginia Power is proposing to convert Bremo Power Station from using coal to natural gas as fuel to generate electricity. In its application filed with the Virginia State Corporation Commission (SCC), Dominion noted that it had agreed to stop using coal and convert the power station by spring 2014 as part of the air permit for the Virginia City Hybrid Energy Center. Virginia Center went into service in July 2012. If the SCC approves the conversion, the company would cease burning coal at the station in the fall of 2013.

Bremo Power Station is the oldest coal-fired power station managed by Dominion. Bremo's two generating units can generate 227 megawatts of electricity.
The station generates about 3 percent of all the power used by the homes, businesses and industries in the company's 30,000-square mile service area.
The station's first two generating units went into service in 1931 and had a total capacity of 30 megawatts. After operating longer than their projected lifetimes, those units were removed from service in 1972.
The third and fourth Bremo units went into service in 1950 and 1958 respectively. Unit 3, the smaller of the two, has a capacity of 71 megawatts. Unit 4 has a capacity of 156 megawatts.
Bremo Power Station is located adjacent to the historic James River near Bremo Bluff, Virginia, in Fluvanna County.
As with any coal-burning power station, Bremo produces particles known as fly ash. After the smoke, or flue gas, containing fly ash leaves the station's boilers, it passes through electrostatic precipitators.
The precipitators act like giant electric air cleaners and remove about 99 percent of the ash and other particles contained in the gases. The cleansed gases are then vented to the atmosphere through one of two tall stacks at the station.
Bremo Power Station also uses low nitrogen oxide (NOx ) burners that reduce the gas from the flue emissions. Nitrogen oxide is one of the causes of air pollution.
The fly ash removed from the gases, together with ash from the bottom of the boilers, is loaded on trucks and hauled to a disposal site near the station where it is disposed in an environmentally safe manner.
