Nation's largest nuclear fleet gets bigger

April 4, 2014 | By Barbara Vergetis Lundin

Three nuclear energy plants owned by Constellation Energy Nuclear Group, LLC (CENG) have joined Exelon Generation's nuclear fleet, which includes five reactors capable of generating more than 4200 MW at full power. The fleet was already the nation's largest commercial nuclear operation.

The reactors include R.E. Ginna Nuclear Power Plant in Ontario, N.Y., a single 583 MW pressurized water reactor; Nine Mile Point Nuclear Station in Scriba, N.Y., two boiling water reactors totaling 1937 MW; and Calvert Cliffs Nuclear Power Plant in Lusby, Md., two pressurized water reactors totaling 1768 MW.

The Nuclear Regulatory Commission determined that Exelon meets the agency's financial and technical qualifications requirements, and concluded that public health and safety will not be adversely affected by the transfers.

The consolidation, an organizational and operational realignment as opposed to a purchase or transfer of assets, follows the March 2012 merger between Exelon and Constellation Energy Group Inc., expanding Exelon's fleet of reactors to 23 nuclear generating units at 14 locations in Illinois, Pennsylvania, Nebraska, New York, New Jersey, and Maryland. In total, the units have the capability to generate more than 22,000 MW.

Electricite de France (EDF) and Exelon remain co-owners of CENG, with Exelon owning 50.01 percent of CENG and EDF 49.99 percent. Through the merger, Exelon became EDF's joint venture partner in CENG with one of the cleanest and lowest-cost power generation fleets in the nation.
