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.

NRG Announces Plans for New Nuclear Reactors in Texas
LCG, June 22, 2006--NRG Energy, Inc. (NRG) announced yesterday plans to develop approximately 10,500 MW of new electric generating capacity in the United States, including 2,700 MW of new nuclear capacity. The plan would be implemented over the next ten years and would require a total estimated investment of $16 billion.
The plan calls for the construction of two nuclear reactors at the existing South Texas Project (STP) nuclear facility. NRG filed a letter of intent with the Nuclear Regulatory Commission on June 19 to add 2,700 MW of nuclear generating capacity. NRG's estimated construction cost for Units 3 and 4 is $5.2 billion, and operations for the two units are scheduled to commence in 2014 and 1015.
NRG's nuclear plans are based upon General Electric Company's Advanced Boiling Water Reactor (ABWR) nuclear power plant technology, which has been licensed in the United States, Japan and Taiwan. NRG stated that it intends to work with GE and Hitachi,(which has been involved in developing and constructing four ABWR plants in operation in Japan) to construct the nuclear power plants.
NRG's overall development plan calls for nearly 8,000 MW of new baseload capacity and 2,500 MW of new, highly efficient intermediate and peaking capacity. The new baseload capacity includes three coal-fired plants in the Northeast that will employ an advanced, Integrated Gasification Combined Cycle (IGCC) design. One of NRG's underlying strategies embedded in its plan is to add capacity adjacent to existing generating units to leverage existing infrastructure and generally minimize both incremental environmental impacts and costs.
NRG stated that the investments in new capacity will be underpinned by long term off-take contracts and hedges that support non-recourse project financing, together with third party equity partners and the Company's existing cash flows.
