b. Pure capital cost of a 600 MW super critical coal plant is expected to be 2000 US$/kW. Construction period is about 4 years, and the annual capital disbursement is expected to be 0.15, 0.35, 0.35 and 0.15 respectively. Assuming 10% discount rate, calculate the IDC and the actual capital cost of the project. c. Table Q2 shows the investment, maintenance and fuel costs of nine thermal power plants.
