Arkansas Nuclear One says it's returned to service one of its nuclear units that's been offline since an accident in March that killed a worker.
Entergy says Unit 1 needed "extensive restoration efforts" after the accident that killed worker Wade Walters.
He died when a crane failed, causing a piece of heavy equipment to fall on him. The accident happened in a non-nuclear area of the plant.
The company says Unit 1 was reconnected to the grid late Wednesday night.
Entergy owns and operates power plants with about 30,000 megawatts of electric-generating capacity, including more than 10,000 megawatts of nuclear power.
The company provides electricity to 2.8 million customers in Arkansas, Louisiana, Mississippi and Texas.
