RICHMOND, Va. (AP) — Dominion Virginia Power has started commercial operations at its Virginia City Hybrid Energy Center in Wise County as part of its blueprint to meet growing energy demands and comply with changes to environmental regulations.

The Richmond, Va., energy provider said Wednesday that the 585-megawatt power station in St. Paul was placed in commercial operation late Tuesday after four years of construction that employed nearly 2,400 workers at its peak. The $1.8 billion power station uses coal, waste coal and biomass to produce enough to power 146,000 homes at peak demand.
