LCG, December 16, 2025--The Nuclear Regulatory Commission (NRC) announced today that it has renewed the operating licenses of Constellation LLC’s Clinton Unit 1 in Clinton, Illinois, and Dresden Units 2 and 3, near Morris, Illinois, for an additional 20 years beyond the current expiration dates. The combined capacity of these three, Illinois-based nuclear units is 2,925 MW, and the operating license extension will enable the units to generate carbon-free power through about 2050.

LCG, December 12, 2025--Today, the Electric Reliability Council of Texas, Inc. (ERCOT) announced strategic organizational changes designed to accelerate innovation, strengthen grid reliability, and support the unprecedented growth in the demand for electricity across Texas. To meet these objectives, ERCOT created two new organizations: Interconnection and Grid Analysis, and Enterprise Data and Artificial Intelligence (AI). The two organizations will formally launch in January 2026.

Progress Energy May Develop Nuclear Plants in Both Florida and the Carolinas
LCG, November 2, 2005--Progress Energy yesterday announced that it plans to seek licenses to build up to four nuclear reactors at two locations, with one site in Florida and another in the Carolinas. The company plans to submit applications for both sites to the U.S. Nuclear Regulatory Commission (NRC) by 2008. Construction would begin two years later, with operations commencing as early as 2015.Progress Energy previously notified the NRC on August 29, 2005 that its plans may result in its submittal of one combined construction and operating license (COL) for a new nuclear power plant in Florida. At that time, Progress Energy also notified the NRC that it expects to select a potential site and reactor vendor by the end of 2005.The announcement that Progress Energy plans to submit a second license highlights the renewed efforts to develop nuclear reactors in the Southeast. Last week, Duke Power announced that it is preparing a combined COL application to construct two nuclear reactors. Southern Nuclear Operating Company announced in August that it has selected its Vogtle Nuclear Station in Georgia for consideration as a site for new nuclear units. SCANA, the parent company of South Carolina Electric and Gas Co., and Santee Cooper announced in August that they are considering extending an existing nuclear generation joint ownership agreement so that they can study construction of a new nuclear generation facility. (The two companies currently co-own the V.C. Summer Nuclear Station near Jenkinsville, South Carolina.)The NuStart Energy Development, LLC, a consortium founded last year to support the development of new nuclear power, announced in September that its two finalist sites for the development of new nuclear reactors are Grand Gulf Nuclear Station (owned by Entergy Nuclear) in Port Gibson, Mississippi and Bellefonte Nuclear Plant (owned by the Tennessee Valley Authority) near Scottsboro, Alabama. NuStart plans to prepare applications to the NRC for combined COL. One application will be for a GE Economic Simplified Boiling Water Reactor (ESBWR) and one application will be for a Westinghouse Advanced Passive 1000 (AP1000) reactor.Both the GE and Westinghouse designs incorporate passive safety features that rely upon natural forces, such as gravity, in order to reduce reliance on active, mechanical systems, like pumps and valves. The Westinghouse AP1000 reactors are each able to generate 1,100 MW of electricity. According to Westinghouse, the AP1000 is scheduled to receive Design Certification in December 2005.GE submitted its Design Certification application to the NRC for its 1,500-MW, ESBWR design in August and anticipates the Final Design Approval toward the end of 2006, with the Design Certification received immediately thereafter.Progress Energy is a participant in NuStart Energy Development, LLC, a consortium founded in 2004 to support the development of new nuclear power stations. Other participants include Exelon, Entergy, Southern Company, Constellation, Duke Energy, the Tennessee Valley Authority, Florida Power & Light, EDF International, and the two reactor vendors, GE and Westinghouse Electric.
