A 50 MW combined-cycle plant with a heat rate of 7700 Btu/kWh operates with a 50-% capacity factor. Natural gas fuel now costs $5 per million Btu (MMBtu). Annual O&M is 0.4¢/kWh. The capital cost of the plant is $600/kW. The utility uses a fixed charge rate (FCR) of 0.12/yr.
a. What is the annualized capital cost of the plant ($/yr)?
b. What is the annual electricity production (kWh/yr)?
c. What is the annual fuel and O&M cost ($/kWh)?
d. What is the current cost of electricity from the plant ($/kWh)?
e. If fuel and O&M costs escalate at 6 percent per year and the utility uses a discount rate of 0.14/yr, what will be the levelized bus-bar cost of electricity from this plant over its 30-yr life?
