Briefings

MIT Technology Review reports that Constellation plans to add nearly 1 gigawatt across 11 reactors at six plants, while the DOE awarded a $4.2 billion loan to Vistra for upgrades at three plants. These projects aim to increase capacity by roughly 433 megawatts, potentially powering 700,000 homes. The Constellation project is funded by Google's 20-year electricity purchase agreement, and Vistra's upgrades are supported by a $4 billion DOE commitment. While uprates can boost capacity by up to 20%, recent major uprates like Browns Ferry's 14% expansion show that significant equipment replacement is required. Current US nuclear capacity is 98 gigawatts, with potential uprates estimated between 3 and 8 gigawatts, though PJM expects 30 gigawatts of additional demand by 2030 from AI, meaning nuclear uprates would cover only a fraction of that need.

Key points

• Constellation plans to add nearly 1 gigawatt of new capacity across 11 existing reactors at six US plants.
• The DOE awarded a $4.2 billion loan to Vistra for upgrades at three plants, adding 433 megawatts of capacity.

Context and limitations

Data reflects plans and funding announcements up to October 2026; actual implementation timelines and final capacity gains remain uncertain.
