Photos: Dominion Energy utilizes "solar grazing" at solar farm in Sussex County
Dominion Energy uses flocks of sheep at their six solar farms around the state of Virginia to keep grass and vegetation at bay, known as "solar grazing". So far, the company has about a combined 1,000 sheep on their solar farms from a company called Gray's LAMBscaping, founded by Jess and Marcus Gray. The use of sheep, as opposed to mowing, is environmentally friendly by keeping the vegetation in a more natural state and reducing water runoff.
