The Paris-based International Energy Agency released its annual report on global electricity systems and markets on February 6, showing the output of nuclear energy at record levels in 2025. According to Electricity 2026, nuclear energy together with renewable energy sources (mainly solar) will generate about half of all global electricity by 2030, up from 42 percent today.

Ontario Power Generation, Canada's leading power generator, has completed construction work on its massive Darlington refurbishment project, the utility announced yesterday. The overall project is forecast to be delivered four months ahead of schedule and C$150 million (about $110 million) under budget, OPG stated, adding that station staff are now completing final testing on the Unit 4 reactor in preparation of its return to full commercial operation.

The Nuclear Regulatory Commission has agreed to review an early site permit (ESP) renewal application submitted by Entergy last September for its Grand Gulf site in Mississippi, currently home to one 1,433-MWe boiling water reactor. The initial ESP for the site had been issued in 2007, following a 2003 application submittal.

On a call with investors this week, NextEra announced that it is considering new nuclear development at its existing sites, as well as projects at greenfield sites.
As the company eyes new development, work on the restart of Duane Arnold hit another milestone this month, with Linn County approving the project’s rezoning application.

Utah-based EnergySolutions announced on January 15 that it has submitted a notice of intent to the Nuclear Regulatory Commission, confirming that the company plans to submit an application for a “major licensing action” for new nuclear generation at the closed Kewaunee nuclear power plant in Wisconsin. Applications for an early site permit, construction permit, or combined license are currently being evaluated, the company said.
Gov. Hochul delivers her 2026 State of the State address in Albany, N.Y. (Photo: Darren McGee/Office of Gov. Kathy Hochul)
In June of last year, New York Gov. Kathy Hochul called on the New York Power Authority—the state's public power utility—to add at least 1 GW of new capacity to the electrical grid through the construction of an advanced nuclear power plant in upstate New York to support the state’s decarbonization goals.
It was good news for the nuclear community, to be sure, but in Hochul's State of the State address in Albany earlier this week, she made that objective sound almost unambitious.

On New Year’s Eve, Holtec International submitted Part 1 of a construction permit application to the Nuclear Regulatory Commission seeking a limited work authorization (LWA) to begin construction of a two-unit SMR-300 plant at the company’s site in Covert, Mich.
Named Pioneer-1 and -2, the twin 340-MWe pressurized water reactors would join the 777-MWe Palisades PWR that began operating in 1971, shut down in 2022, and is expected to reconnect to the grid—slightly delayed—early this year. According to Holtec’s application documents, Part 2 of its construction permit will be filed no later than mid-2027.

In 2025, New York Gov. Kathy Hochul was a vocal supporter of new nuclear development in the state. In October, she called on the New York Power Authority (NYPA)—the state’s public electric utility—to add 1 GW of new nuclear.
At the tail end of December, New York made more nuclear progress on three fronts. Hochul signed an agreement with Ontario Premier Doug Ford to collaborate on new nuclear development, Ontario Power Generation (OPG) signed a memorandum of understanding with the NYPA, and New York finalized its 2025 energy plan.
