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.

Duke Submits COL Application for New Nuclear Power Station
LCG, December 14, 2007--Duke Energy yesterday submitted a combined construction and operating license (COL) application to the Nuclear Regulatory Commission (NRC) for the William States Lee III Nuclear Station. The new generating capacity is needed to meet Duke Energy Carolina's forecast growth in electric demands.
Unlike most plans to construct nuclear reactors in the United States, Duke proposes to build the two reactors at a greenfield site, rather than to add new capacity at an existing nuclear power station. The site is located in Cherokee County, South Carolina.
Duke selected Westinghouse Electric's AP1000 design for the William States Lee III Nuclear Station. The AP1000 design incorporates passive safety features. The NRC approved the Design Certification on December 30, 2005. The proposed two units will have a combined electric generating capacity of 2,234 MW.
Duke's COL application relies upon the COL application submitted October 31, 2007 to the NRC by the Tennessee Valley Authority (TVA) and NuStart Energy, a consortium of nuclear energy companies, to build two nuclear reactors at TVA's Bellefonte site in northern Alabama. Other companies that have announced the selection of the AP1000 design as the basis for additional COL applications to construct reactors include Progress Energy, Southern Company, SCANA and Santee Cooper.
