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 Carolinas Files Application to Construct 750-MW Combined Cycle Facility

LCG, October 29, 2013--Duke Energy Carolinas last Thursday filed an application for a Certificate of Environmental Compatibility and Public Convenience and Necessity (CECPCN) with the Public Service Commission of South Carolina (PSCSC) requesting approval to build and operate a 750-MW natural gas-fired combined cycle plant at the existing Lee Steam Station in Anderson County, South Carolina. North Carolina Electric Membership Corporation (NCEMC) will be a minority owner of 100 MW of the project if constructed.

Duke Energy State President - South Carolina stated, "The energy needs of our customers are significant over the next 15 years. Our commitment is to meet our customers' needs in a way that balances affordable, reliable and increasingly clean electricity, and this project will help us satisfy that need."

Duke has made no final decision to construct the new facility at the Lee Steam Station and is proceeding with regulatory actions that are necessary to keep the project moving forward.

The Duke executive stated, "The Lee site is a great location for a combined cycle plant. Duke Energy will be able to leverage existing site infrastructure to minimize new generation project costs and impacts to the community and environment."

The existing site includes coal-fired units and two gas-fired turbines. Construction could commence once the necessary regulatory approvals are received, with commercial operation achieved as soon as June 2017, according to Duke.
