China starts 8 large reactor builds 2025-2026, targets 2030 capacity lead over US and EU

Construction began on eight large reactors in China from January 2025 through May 2026. The builds follow a uniform licensing and project management system applied to batches of six or more units. Average completion time stands at 5-7 years versus the global 9-year mean and 15 years for Vogtle 3 and 4. Government capital and supply-chain repetition cut schedule variance. Data from IAEA PRIS and World Nuclear Association records show China nuclear capacity reached 58 GW in 2024 and is projected to surpass the US fleet before 2030. Each new unit adds roughly 1.1 GW at capital costs below $3,000 per kW after learning-curve effects. Small modular reactor prototypes remain pre-commercial; Antares Mark-0 reached criticality without power-conversion systems and targets grid output no earlier than late 2027. Large standardized reactors already deliver dispatchable zero-carbon power at scale while SMRs have not yet demonstrated factory production or regulatory repeatability. China’s approach extracts economies at gigawatt size rather than waiting for miniaturization. This trajectory adds firm supply that can displace coal and moderate wholesale price spikes once units reach commercial operation after 2030. No new Chinese reactors will connect to any grid inside the next 12 months, so electricity bills for millions will remain unaffected by these builds until at least 2031. Global LNG and coal price linkages will continue to dominate short-term rate movements.
