Expectations for increases in power demand, particularly from energy-intensive data centers, and decarbonization goals have helped spark renewed interest in nuclear power. As we’ve discussed in previous blogs, that includes the return to service of the Palisades nuclear power plant in Michigan, which could happen as soon as this year; the restart of Unit 1 at the Three Mile Island nuclear plant in Pennsylvania; and projects that co-locate data centers and nuclear power.

Those efforts are continuing, with recent developments at three other sites:

  • NextEra Energy has filed notice with federal regulators about a possible restart of its Duane Arnold nuclear power plant in east-central Iowa. The plant closed in October 2020 after its power purchase agreement (PPA) with Alliant Energy expired. The single-unit reactor started in 1975 and was licensed to operate until 2034. CEO John Ketcham said in a January 24 earnings call that the plant could be back online by 2028.
  • South Carolina utility Santee Cooper said January 22 that it would start accepting bids from buyers interested in completing a pair of nuclear reactors at the V.C. Summer power plant that were left uncompleted in 2017. After breaking ground in 2013 with an expected cost of $9.8 billion, that project rapidly suffered cost overruns and schedule delays and, along with cost overruns at the Vogtle power plant in Georgia, led to the bankruptcy of the builder, Westinghouse. The two units were eventually canceled at a cost of just over $9 billion.
  • The California Public Utilities Commission in December approved $722.6 million in ratepayer costs to cover the 2025 operations of both units at the Diablo Canyon nuclear power plant (see photo below) in San Luis Obispo County, about midway between Los Angeles and San Francisco. A deal between legislators and Governor Gavin Newsom in 2022 extended the life of the 2,240-MW plant, which was originally scheduled to begin shutting down in 2024. The plant will now run through 2030 and its operator, Pacific Gas & Electric, has applied to have the plant’s license extended for another 20 years. The plant produces about 9% of the state’s electricity.
