Entergy Corp. on March 19 announced that its Indian Point 2 has entered the last refueling and maintenance outage before the nuclear unit's permanent retirement by April 30, 2020.

The generating unit has been in operations since 1974 and has been generating electricity more than 96% of the time since its prior refueling outage ended in June 2016. For the latest outage, about 2,000 workers will conduct equipment maintenance, safety inspections and refueling of the reactor.

Meanwhile, Indian Point 3 remains in service and will undergo its final refueling outage next spring before its permanent shutdown by April 30, 2021.

The company expects to spend more than $75 million in the plant during the outage.

In January 2017, Entergy said it would shut down the Indian Point Energy Center as part of an agreement with New York state.
