BUCHANAN, NY — A tentative agreement has been reached between owners and workers of Indian Point nuclear power plant Wednesday. The deal, which was made in the early morning hours, must be voted on by the members of Utility Workers Union of America Local 1-2.

Entergy said that both sides agreed on a four-year contract which affects about 330 of the almost 1,000 Indian Point employees.

The agreement between Entergy and union leadership will have to be approved by the union membership in a vote that is expected to take place within the next few weeks. The terms were not disclosed.

“This agreement benefits all parties — the workers, the union, and Entergy. I applaud the union’s negotiating team, led by James Slevin, for its continued discussions to reach an amicable agreement,” said Tony Vitale, site vice president and Entergy’s top official at Indian Point. “All of our employees will continue to focus on their mission to provide reliable power to millions of NewYorkers through the date of permanent closure in 2021.”

Union members voted to strike Jan. 17, but held off on the action.

Indian Point provides up to one-fourth of the electricity for New York City and Westchester County. It will end operations in 2021 under an agreement reached a year ago between Entergy and the state.

The union represents operations, radiation protection, chemistry and maintenance workers at the plant.
