Nuclear power plants generate 2,700 TWH per year, which is 10% of the world’s electricity and around c4% of the world’s total energy supply. Its share of global electricity demand peaked at 17.5% in 1996 and has since lost share.
This data-file models the economics of constructing a new nuclear power project, based on technical papers and past projects around the industry. The economics can be compared with coal, gas, hydrogen, wind or solar.
The challenge is high capex costs and long construction cycles. This means that a CO2 price of $270/ton is required before new nuclear projects would outcompete new gas projects, on an apples-to-apples basis.
