History of Excellence
Entergy operates and owns nuclear power plants in Arkansas, Louisiana, Massachusetts, Michigan, Mississippi, New York and Vermont and has a management contract with Cooper Nuclear Station in Nebraska. With more than 10,000 megawatts of nuclear capacity, Entergy is one of the nation’s leading nuclear electricity generators. Entergy Nuclear’s national headquarters are located in Jackson, Miss.
Entergy Nuclear’s history begins here.
- In 1990 Entergy created Entergy Operations to formalize the nuclear power management company located in Jackson, Miss. Entergy operated five reactors in Arkansas, Louisiana and Mississippi.
- Entergy Nuclear was recognized in 1998 as the “Best of the Best” by the Nuclear Energy Institute for the Grand Gulf “Advanced Resin Cleaning System” chosen from nuclear operator in the United States.
- In 1999 Entergy became the first company in the United States to acquire an operating nuclear plant through competitive bidding when it purchased the Pilgrim Power Plant from Boston Edison.
- Seeing unrealized value of the nation’s nuclear plants, Entergy began the addition of five more nuclear reactors to the five reactors already in Entergy’s service territory. It included the purchase of Indian Point Units 2 and 3 and James A. FitzPatrick Nuclear Power Plant in New York; Vermont Yankee Nuclear Power Station; and Palisades Power Plant in Michigan.
- In 1999 Entergy Nuclear’s Arkansas Nuclear One plant was recognized as the “Best of the Best” by the Nuclear Energy Institute for “Risk-Informed Inspection Program for Piping Welds” marking prestigious back-to-back industry recognition for Entergy Nuclear.
