Investment costs per kW at various costs of capital – 3%, 7%, and 10%.

Net capacity and overnight costs of projects are indicated by country.

However, the cost of capital is not the only parameter determining the successful completion of nuclear new built projects where issues such as electricity market design, project management and incentive structures play important complementary roles.
