In 2019, 5.5 GW of additional nuclear capacity were connected to the grid and 9.4 GW were permanently shut down, bringing global capacity to 443 GW. New projects were launched (about 5.2 GW), and refurbishments are under way in many countries to ensure the long-term operations of the existing fleet. Nevertheless, while the existing nuclear fleet remains the world’s second most important low-carbon source of electricity, new nuclear construction is not on track with the SDS. According to current trends, nuclear capacity in 2040 will amount to 455 GW – well below the SDS level of 601 GW. Additional lifetime extensions and a doubling of the annual rate of capacity additions are therefore required.
