NERC's New Winter Reliability Assessment Raises Concerns for Elevated Risk of Insufficient Supplies to Meet Demand in Extreme Operating Conditions

LCG, November 19, 2025--NERC yesterday released its 2025–2026 Winter Reliability Assessment (WRA), which concludes "much of North America is again at an elevated risk of having insufficient energy supplies to meet demand in extreme operating conditions." The WRA does state that resources are adequate for normal winter peak demand, but extended, wide-area cold snaps will be challenging.

Duke Energy North America Plans Three Merchant Plants

LCG, Jan. 14, 2002--Duke Energy North America has signed contracts with Duke/Fluor Daniel to design and construct three merchant generating plants worth a total of 2,420 megawatts of new capacity.

Jeff Faulk, president and chief executive officer of Duke/Fluor Daniel noted, "This brings our portfolio of active EPC projects to more than 16,000 megawatts of fossil-fueled power generation." The plants will be located in three disparate areas within the western states. The Luna Energy Facility will be located in Luna County N.M., and will have a nameplate capacity of 600 megawatts. In Grays Harbor County, Wash., the 620-megawatt Grays Harbor Energy Facility is planned. Moapa County, Nev., will be home to the 1,200-megawatt Moapa Energy Facility.

Each of the power plants will be a combined-cycle facility, fired by natural gas. Commercial operation of the plants, which will utilize eight General Electric-7FA combustion turbines, is expected starting in the summer of 2003.

Jim Donnell, president and chief executive officer of DENA commented that with Duke/Fluor Daniel's record, he believed that "these facilities will be providing competitively priced power to the western United States when demand peaks in the summer."
