3. Combined-cycle electric generating systems are combustion turbines and steam turbine that are operated together in what is commonly referred to as a power block. These power blocks are high efficiency power systems that produce inexpensive power on demand and are the natural competitor (and complement) to non-dispatchable power systems, e. g., solar and wind, and account for approximately 85% of the natural gas power systems in the United States. A nominal combined cycle power plant has a rated power of 700 MW, a capacity factor of 51.0%, and a heat rate of 6600 Btu/kWh. The plant has an installed cost of $980/kW and is fueled by natural gas. The cost of the natural gas is $3.75/MBtu. The operations and maintenance (O&M) cost of $0.003/kWh. The plant has an expected life of 20 years and a 5.00% discount rate. The electricity has a transmission cost of $0.010/kWh. 3d. What is the levelized cost of electricity for this gas turbine power plant including transmission costs ($/kWh)?
