LCG, August 15, 2025--Xcel Energy announced that the company received state approval yesterday from the Minnesota Public Utilities Commission to extend operations of the Prairie Island nuclear plant through the early 2050s. Prairie Island has two units that have a combined generating capacity of 1,100 MW. The units’ current operating licenses expire in 2033 and 2034.

LCG, August 7, 2025--Portland General Electric (PGE) today announced the completion of three, four-hour lithium-ion utility-scale battery energy storage systems (BESS) in Oregon, adding 475 MW and more than 1.9 GWh of dispatchable capacity to serve the Portland metro area. Each of these BESS facilities can deliver power during peak demand or when other electric generating facilities are limited, which improves system flexibility, reliability and costs.

Unistar Nuclear Energy Engages AREVA-Bechtel Power
LCG, February 5, 2008--UniStar Nuclear Energy, a joint venture between Constellation Energy and the EDF Group, yesterday announced that it has engaged an AREVA-Bechtel Power consortium to start developing the detailed design engineering for UniStar's proposed fleet of advanced nuclear power plants in the United States.
The announcement indicates both growing momentum and commitment by Unistar to develop a fleet of nuclear reactors using AREVA's U.S. Evolutionary Power Reactor (U.S. EPR) design, which is a Generation III+ design based upon AREVA's 1,600-MW, European EPR now being deployed in Europe. In December, AREVA filed its design certification application for the U.S. EPR with the Nuclear Regulatory Commission (NRC). AREVA expects the Design Certification application will be validated by 2010, which would enable a U.S. EPR to be licensed and ready for operation as early as 2015.
UniStar is working to develop U.S. EPRs at a number of sites. Unistar is using the U.S. EPR design in its plans to build a nuclear reactor at Constellation Energy's existing Calvert Cliffs Nuclear Power Plant in Lusby, Maryland. In July 2007 Unistar filed the environmental report portion of a combined construction and operating license (COL) application with the NRC to build the reactor, and Unistar plans to submit the remainder of the application in early 2008. On January 25, the NRC accepted for detailed review UniStar's partial COL application. UniStar plans to submit the remaining portions of the COL application in March.
In December 2007, PPL Corporation announced that it contracted with Unistar to prepare a COL application with one of its subsidiaries to submit to the NRC for approval to build and operate a nuclear reactor using AREVA's U.S. EPR design. The reactor would be built near the Susquehanna nuclear power plant in Pennsylvania. The existing Susquehanna facility is jointly owned by PPL Susquehanna, LLC and Allegheny Electric Cooperative Inc. and is operated by PPL Susquehanna. The application will be submitted by the end of 2008.
