State utility regulators have approved a plan by Entergy Mississippi to increase the output from its Grand Gulf Nuclear Power Plant in Port Gibson.
Approval by the Mississippi Public Service Commission came Monday. Federal regulators also must approve the proposal.
Haley Fisackerly, president and CEO of Entergy Mississippi ( EMO – news – people ), says Grand Gulf’s capacity would rise to 1,443 megawatts from 1,265, a 13 percent increase.
Fisackerly, in a statement released Wednesday, says the total cost, estimated at $510 million, will be shared among the joint owners of Grand Gulf. He said costs to Entergy Mississippi are estimated at $151 million.
