🌐Where are all the Nuclear Power Plants?
October 28, 2025
Nuclear power is now in focus as solving the power deficit needed to supply electricity to new AI data centers that are projected to use 176 gigawatt (GW) by 2035 according to Deloitte. Consider that 1 GW is sufficient to power 850,000 homes for one year.
The last nuclear power plant to go online was Unit 4 of the Vogtle plan in Georgia in May 2024, which generates approximately 1 GW. The last nuclear power plant to go online before Vogtle #4 was twenty years ago.
Where are the rest of the power plants with greater than 1GW of generating capacity? See the list below and map at right (Source: US Energy Information Administration).
