Yorktown Units Allowed to Operate on Emergency Basis

U.S. Secretary of Energy Rick Perry has issued an order allowing the coal-fired Yorktown Units 1 and 2 to operate on a limited basis for three months this summer to prevent uncontrolled power disruptions in the North Hampton Roads area of Virginia. Dominion Energy had planned to shut down the two units to meet Environmental Protection Agency clean-air regulations. But PJM Interconnection, the regional transmission organization serving Virginia, requested the exemption in March.

“I hereby determine that an emergency exists in the Commonwealth of Virginia due to a shortage of electric energy, a shortage of facilities for the generation of electric energy, and other causes, and that issuance of this Order will meet the emergency and serve the public interest,” stated Perry in an order dated June 16.

The units will operate only as needed to reduce the risk of power outages until Dominion Energy’s 500 kV Skiffes Creek transmission line is completed. The units also can be used during transmission construction when existing lines will need to be taken out of service.

A week ago the U.S. Army Corps of Engineers gave a conditional go-ahead to Dominion to build a transmission line across the James River, eliminating the major regulatory barrier to the project. But the utility still needs to obtain permits from the Virginia Marine Resources Commission, a water quality certification from the Department of Environmental Quality, and a permit from the James City County Board of Supervisors for a switching station, reports the Williamsburg Yorktown Daily.

Meanwhile, construction is expected to take a year and a half, leaving the Virginia Peninsula vulnerable to rolling blackouts on days of peak demand in order to avoid an uncontrolled, cascading blackout that could spread way beyond the region.

Dominion had cited the threat of blackouts as justification for hurrying the permitting process, which has dragged on for years. After shutting down the two polluting Yorktown units this spring, the utility instituted a Remedial Action Scheme (RAS) that would immediately drop load to 150,000 customers in the event that  an uncontrolled blackout took place.

“The order provides authority to PJM and Dominion to run the [Yorktown] units only when needed to avoid loss of electric power in the North Hampton Roads area when certain power demand levels are reached,” says PJM spokesman Ray E. Dotter.
