A company desires to estimate the cost of building a 600-MW fossil-fuel plant for the assembly of its new long-distance aircraft. It is known that a 200-MW plan cost $100 million 20 years ago when the approximate cost index was 400, and the cost index is now 1,200. The cost-capacity factor for a fossil-fuel power plant is 0.79. Estimate the cost of the 600-MW plant.
