A tentative agreement has been reached avoiding a possible strike or lockout at the Indian Point nuclear power plant.
Entergy, the plant's owner, and union officials agreed on the last-minute deal early Saturday morning.
Their contract was set to expire at midnight on Friday, and the workers had authorized a walkout if no agreement was reached.
A statement from Entergy said that the agreement allows workers to focus on their mission of safely providing affordable and reliable power to the city.
The union's spokesman confirmed the tentative deal and said that it benefits the workers, the union and Entergy.
According to Entergy, Indian Point generates about 25 percent of the power used in the city and Westchester County.
Union members have to approve the deal in a vote expected within the next few weeks.
