Utility Entergy Corp. is in talks with some of its biggest customers about deploying small nuclear reactors as electricity demand surges from factories and artificial intelligence data centers, said Chief Executive Officer Drew Marsh.

The utility, which serves a heavily industrialized portion of the Gulf Coast, owns four large-scale nuclear plants and is considering upgrades to them that would, together, generate perhaps another 400 megawatts of electricity, Marsh said. But the cost of developing new nuclear plants is too great for Louisiana-based Entergy to finance on its own.
