Owner wants to close Salem power plant by June 2014

SALEM — Energy provider Dominion Resources Inc. has asked the regional electricity grid manager to allow it to permanently close its Salem Harbor Power Station in Massachusetts by June 2014.

Virginia-based Dominion said yesterday it made the request to ISO New England on Feb. 10. ISO has 90 days to determine if it will need the plant to ensure reliable electricity delivery.

ISO can’t force the station to stay open, but it could negotiate a deal with Dominion that sees ratepayers covering needed upgrades to keep it running.
