TerraPower Announces Start of Construction on First Utility-Scale Advanced Nuclear Plant in Wyoming

LCG, April 23, 2026--TerraPower announced today the official start of construction on its Kemmerer Unit 1 nuclear power plant, which could be the first utility-scale advanced nuclear power plant in the United States. In early March, the Nuclear Regulatory Commission (NRC) announced that it had authorized the staff to issue a construction permit for Unit 1 commercial nuclear power plant in Kemmerer, Wyoming.

TVA Announces Two Energy Storage Agreements Totaling 425 MW/1,700 MWh

LCG, April 22, 2026--The Tennessee Valley Authority (TVA) yesterday announced two new, 20-year agreements for a 225 MW/900 MWh battery energy storage system (BESS) project in East Tennessee and for a 200 MW/800 MWh BESS project in northern Alabama. Both projects are planned to commence commercial operations in 2029.

NRC Issues Subsequent License Renewals for First Time to Nuclear Reactors in Florida

LCG, December 11, 2019--The Nuclear Regulatory Commission (NRC) staff recently approved Florida Power & Light's (FPL's) application for an additional 20 years of operation for Turkey Point Nuclear Generating Units 3 and 4. This is the first time the NRC has issued renewed licenses authorizing reactor operation from 60 to 80 years. The subsequent (or second) license renewals (SLRs) for Turkey Point Unit 3 and Unit 4 now expire on July 19, 2052 and April 10, 2053, respectively.

The Turkey Point Nuclear Generating Units 3 and 4 are located on Biscayne Bay, approximately 24 miles south of Miami and just east of the Homestead area. The first unit began commercial operation in 1972, and the second unit followed in 1973. The units are Westinghouse pressurized water reactors (PWRs) that provide a combined electric generating capacity of 1,632 MW.

FPL submitted the Turkey Point SLR application on January 30, 2018, amending the application with additional information through April 10, 2018. The initial operating license for a nuclear reactor covers 40 years. A 20-year license renewal may then extend operations to 60 years of operations. The SLR process determines whether an operating reactor can safely extend its license for an additional 20 years (from 60 to 80 years of operation).

Roughly half of the nation's nuclear power plants will need to obtain an SLR by 2040 to continue operations. NRC approval of the first SLR is an important milestone for the nuclear industry and its potential to provide carbon-free electricity to 2050 and beyond.
