Dominion Resources will shutter its Yorktown coal plant in April, and afterwards may need to use rotating blackouts on the Virginia Peninsula in order to maintain grid reliability and avoid voltage collapse.
The Yorktown's two units do not run often, and violate environmental emissions standards. They are required to close by law, RTO Insider reports, and once they are offline, the grid will become unstable.
The Army Corps of Engineer is considering a transmission line could replace the lost power but it will need to cross the James River, and that proposal has many opponents. The design calls for more than a dozen transmission towers.
