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.

St. Lucie County Blocks FPL's Proposed Coal Plant
LCG, November 9, 2005--The St. Lucie County Commission unanimously voted to block the development of a new coal plant in the Bluefield area proposed by Florida Power & Light (FPL). The opposition from local officials and citizens was largely tied to perceived environmental impacts associated with burning coal, rather than the construction and operation of a new power plant. FPL announced its plans in February to build a new, coal-fired station in St. Lucie County in order to meet Florida's growing demand for electricity. The proposal was to construct two, 850-MW units that employ a supercritical pulverized coal design. The first unit was to begin operations in 2012, with the second unit generating power in 2013.The project was proposed following a study published by the State of Florida that was generally favorable towards the development of new coal plants. In that most of the generation installed in Florida over the past ten years is gas-fired, the development of new coal plants would provide for greater fuel diversity.With Florida's growing electricity requirements and the new heights that natural gas prices have reached, a number of new coal plants are under consideration at this time. In July, Tallahassee Electric Utility, JEA, Florida Municipal Power Agency and the Reedy Creek Improvement District announced that they are exploring the development of an 800-MW, $1.4 billion coal plant in northern Florida. The new station would be operational in 2012. In March, Seminole Electric Cooperative, Inc. announced plans to add a third, 750-MW coal-fired unit at its existing 1,300 MW Seminole Generating Station. Like the JEA project, the target date for operations is in 2012. Seminole states that the new capacity is needed to provide reliable, economical energy supplies to its ten member systems in Florida.Roughly a year ago, Orlando Utilities Commission (OUC) and Southern Power, the unregulated subsidiary of Southern Company, announced plans to develop a 285-MW, advanced coal plant to be built at OUC's existing Stanton Energy Center near Orlando, Florida. The operational date for this project is 2010. Gainesville Regional Utilities has also explored the development of a 220-MW, coal-fired plant, with operations planned for 2011.If other local governments follow the path taken by St. Lucie County, it will be interesting to see how Florida manages to supply its demand for electricity.
