ST. PAUL, Va. (AP) — Dominion Virginia Power says its power plant in Wise County has used nearly 1.1 million tons of waste coal since it began operating in July 2012.
The Richmond-based energy provider says Virginia City Hybrid Energy Center near St. Paul uses waste coal from old mining operations as fuel for the power station.
Dominion says the waste coal, also called "gob," is piled along streams and rivers in Southwest Virginia. It is mostly rock and lower-quality coal. About 80 percent of the gob used at the station has come from Virginia.
In addition to waste coal, the power station also is designed to be able to burn waste wood from timbering operations. Officials are hoping to ramp up use of that renewable biomass as fuel at the facility.
