Allied Power will continue to provide maintenance at 12 Constellation nuclear plants through mid-August 2028, per an extension signed by the companies. The new agreement includes staff augmentation and has an option for a five-year renewal.

The 12 plants are located in Illinois, Maryland, New York and Pennsylvania.

Allied Power provides a range of services, from routine maintenance to outage services and management, capital construction and specialized support – for power plants throughout the U.S.

Constellation is the largest owner and operator of nuke plants in the U.S. In October 2022 we reported the Exelon spinoff plans to ask the Nuclear Regulatory Commission (NRC) to extend the operating licenses of its Clinton and Dresden nuclear plants in Illinois by an additional 20 years.

If approved by the NRC, Clinton could operate until 2047 and Dresden could operate until 2049 (Unit 2) and 2051 (Unit 3).
