A proposed pumped hydroelectric storage power station in Southwest Virginia would bring approximately $576 million in economic benefits to the state — half of it to the coalfields region, Dominion Energy announced Thursday.

The figures were revealed in a new study conducted by Richmond-based Chmura Economics & Analytics and commissioned by Dominion.

The report also found that the project would support nearly 3,000 Virginia jobs during development and construction, including more than 2,000 in the coalfield region. Once in operation, the facility would produce about $12 million annually in tax revenue for local governments in Southwest Virginia, according to Chmura.

“We are very excited about the prospect of bringing another major capital investment to the coalfield region of Southwest Virginia,” said Mark Mitchell, vice president of generation construction. “The entire grid system will benefit from having this new generation once it comes online, and the local area will benefit from the jobs and economic benefits that will come from it.”

Dominion is considering two sites, an abandoned mine in Wise County and a 4,100-acre site in Tazewell County.
