At peak output, these facilities will produce 56 megawatts (MW) of emission-free generation, enough to power more than 14,000 homes.

Dominion Virginia Power Generation Construction vice president Mark D. Mitchell said: "The successful completion of these solar projects is a result of the proficient collaboration between Dominion, the counties and the skilled crafts personnel that worked diligently and safely to get the job done.

"We remain focused on meeting the energy needs of customers, and adding to our solar generation fleet continues to play an essential role in that effort."

Amec Foster Wheeler, Dominion's construction contractor, managed the facilities through the engineering and environmental permitting process in the first half of 2016, and completed construction over the next five months to become operational in December 2016.

Most of the construction workers were hired locally within all three counties resulting in an economic boost for the Commonwealth. 

Dominion acquired the solar development in Isle of Wight from Coronal Development Services and the development in Powhatan from Virginia Solar. The facility in Louisa was developed by Dominion.
