“Peaker plants” are small electric generating plants that produce electricity for brief periods during high demand. Older peakers were often powered by oil. Newer peakers are powered by natural gas. In early November Dominion Energy floated an RFP (request for proposal) for companies to build a series of peakers (no smaller than 50 megawatts) totaling a combined 1,500 MW to come online beginning 2022 in Virginia. A month later, following criticism from a competitor, Dominion has canceled the RFP…at least for now.
