An integrated, combined cycle power plant produces 280 MW of electricity by gasifying coal. The capital investment for the plant is $460 million, spread evenly over two years. The operating life of the plant is expected to be 25 years. Additionally, the plant will operate at full capacity 77% of the time (downtime is 23% of any given year). The MARR is 8% per year. a. If this plant will make a profit of two cents per kilowatt-hour of electricity sold to the power grid, what is the simple payback period of the plant? Is it a low-risk venture? b. What is the IRR for the plant? Is it profitable?
