The capacity of nuclear reactors under construction is one of the highest levels seen in the last 30 years with plants with a combined capacity of 78 GW under construction in 15 countries, the International Energy Agency (IEA) has said.

Half of capacity under construction globally is in China, with total installed capacity in the country expected to reach 100 GW by around 2030.

Among other emerging market and developing economies, Egypt, India and Turkey each have around 5 GW under construction. In advanced economies, Japan, South Korea and the UK each have two reactors under construction, while Slovakia has one. Their combined capacity is 9.5 GW. Japan continues to restart reactors whose operations had been suspended.
