Entergy is considering expanding its nuclear power generation capacity and exploring new nuclear technologies with the Louisiana electric utility mulling building a new reactor in Mississippi and upgrading existing plants, company executives said.

New Orleans-based Entergy, which provides electricity to parts of Arkansas, Louisiana, Mississippi, and Texas, is exploring several operations for increasing its approximately 5,000 MW of nuclear capacity, executives said on its earnings conference call.

The company owns and operates a fleet of reactors in four locations in the southern US. They are two units at the Ano nuclear station in Arkansas and single units at Grand Gulf in Mississippi, River Bend in Louisiana and Waterford, also in Louisiana.
