LCG, February 24, 2026--The AES Corporation (AES) and Google today announced agreements for clean power generation that will be co-located with a new Google data center in Wilbarger County, Texas. The agreements include a 20-year Power Purchase Agreements (PPA) for co-located power generation. These coordinated energy projects and powered land will enable Google to rapidly expand its operations to meet demand for core services, while AES will expand its power generation portfolio.

NRC Approves the Natrium® Reactor Construction Permit for TerraPower's Wyoming Nuclear Project
LCG, March 5, 2026--The Nuclear Regulatory Commission (NRC) announced yesterday that it has authorized the staff to issue TerraPower’s subsidiary, US SFR Owner, a construction permit for the company’s Kemmerer Power Station Unit 1 commercial nuclear power plant in Kemmerer, Wyoming.
TerraPower’s project is the first commercial reactor the NRC has approved for construction in nearly a decade and the first approval for a non-light water reactor in more than 40 years. NRC staff finished their technical review of this new design in less than 18 months. The NRC's Chairman stated, "This is a historic step forward for advanced nuclear energy in the United States and reflects our commitment to delivering timely, predictable decisions grounded in a rigorous and independent safety review."
TerraPower’s president and CEO said, "Today is a historic day for the United States’ nuclear industry. We are beyond proud to receive a positive vote from the Nuclear Regulatory Commissioners to grant us our construction permit for Kemmerer Unit One. This is the first commercial-scale, advanced nuclear plant to receive this permit.
Our team has worked relentlessly for over 4 years with the NRC staff to get to this moment. We had extensive pre-application engagement with the NRC; and we submitted a robust and thorough construction permit application almost 2 years ago. We have spent thousands of manpower hours working to achieve this momentous accomplishment.
We plan to start construction on the Natrium plant in the coming weeks and look forward to bringing the first Natrium reactor and energy storage system to market in the great state of Wyoming."
The advanced nuclear project uses the Natrium plant design that includes a 345-MW sodium-cooled fast reactor with a patented molten salt-based energy storage system that can boost the system’s output to 500 MW of power when needed. The project is designed to keep base output steady, ensuring constant reliability, with the ability to quickly ramp up when demand peaks. This energy storage system is unique to TerraPower's advanced reactor design.
The NRC stated that after a streamlined mandatory hearing process, the Commission authorized its Office of Nuclear Reactor Regulation to issue the permit, having found the staff’s review of the Kemmerer application adequate to make the necessary regulatory safety and environmental findings. The staff expects to issue the permit soon.
TerraPower filed the application in March 2024, requesting a permit to build the sodium cooled, advanced reactor design on a site near an existing coal-fired power plant. The NRC staff accepted the application and began formal review in May 2024. Initially the NRC established a 27-month review schedule. In 2025, the review process was streamlined due to TerraPower’s complete application, the company’s responsiveness to questions, the NRC staff’s dedication to the review process, Congressional support with the Nuclear Energy Innovation and Modernization Act and President Trump’s Executive Orders that support nuclear energy. The review was completed in just 18 months - nine months less than originally planned.
The NRC staff issued its safety evaluation for the permit in December 2025, and the final environmental impact statement for the site in October 2025. US SFR Owner will need to submit a separate operating license application, and the NRC staff will need to approve it before the facility can operate.
This first Natrium plant is being developed through the U.S. Department of Energy’s Advanced Reactor Demonstration Program (ARDP), a public-private partnership. That project is expected to be completed in 2030 and is likely to be the first utility-scale advanced nuclear power plant in the U.S.
TerraPower is poised to expand its nuclear footprint. On January 9, 2026, TerraPower and Meta announced an agreement to develop up to eight Natrium reactor and energy storage system facilities in the U.S., which would provide Meta with up to 2.8 GW of carbon-free, baseload energy. Adding the Natrium technology’s energy storage system would boost total output to 4 GW of electric capacity. Under the commercial agreement, Meta will provide funding to support the deployment of the Natrium plants.
TerraPower's president and CEO said in the announcement, "To successfully address growing energy demand, we must deploy gigawatts of advanced nuclear energy in the 2030s. This agreement with Meta is designed to support the rapid deployment of our Natrium technology that provides the reliable, flexible, and carbon-free power our country needs. With our first Natrium plant under development, we have completed our design, established our supply chain, and cleared key regulatory milestones. These successes mean our TerraPower team is well-positioned to deliver on this historic multi-unit delivery agreement."
Meta's Director of Global Energy added, "Meta is committed to supporting innovative energy solutions that can deliver reliable, scalable, and clean power for our operations and the communities we serve. This agreement with TerraPower – the result of Meta’s nuclear RFP process, which identified leading developers of nuclear energy to help us advance our energy goals – marks a significant step forward in advancing next-generation nuclear technology. Supporting new nuclear energy generation spurs job growth, drives innovation in our local communities, and reinforces America’s leadership in energy technology."
