Exelon nuclear plant closing 10 years early

The nation’s oldest nuclear power plant will close in 2019 — 10 years earlier than planned — but will not have to build costly cooling towers, according to two people with direct knowledge of the situation.

The people, who spoke to The Associated Press on Wednesday on condition of anonymity because they weren’t authorized to discuss the plans ahead of an announcement expected Thursday, said the Oyster Creek Nuclear Generating Station in the Forked River section of Lacey Township will close a decade earlier than called for under its current license.

In return, the aging plant, owned by Chicago-based Exelon Corp., will not be required to build one or more cooling towers to replace its current technology, which draws 1.4 billion gallons of water a day from Barnegat Bay, killing billions of aquatic creatures each year. Get the full story »

Vermont politics could, however, complicate any potential sale. Earlier this year, the state Senate voted overwhelmingly to shut the reactor and the person heading that effort is now the unofficial Governor-elect Peter Shumlin, a Democrat.

Analyst Brian Chin said the likely bidders could include other nuclear operators like Exelon Corp., NextEra Energy Inc. and Constellation Energy Group Inc. Get the full story »
