Both power plants are used to provide power to the grid at times of peak demand. In the following the turbines specifications and wind resources are given, together with financial parameters and CO emission considerations. Wind turbine: rated power output 2MW (5 turbines are installed) at 80 m. Wind resources: wind site modelled with Weibull probability function with a k=2.52 and c=7.1 m/s at 10 m. Terrain roughness length z =0.01 m. Wind Turbine Power curve as following: wind Power output speed m/s (kW) 0 0 1 0 2 0 3 21 4 85 5 197 2 0 Quiz:

Cost of gas is 2.7 $/MMBTU (1BTU=1055 J, 1MMBTU=10 BTU). Greenhouse emission factor for gas is 57.2 kg CO -e / GJ. Capital cost of the wind turbine is $ 1800/kW, Annual O&M is 5% of the capital cost, while the salvage value at the end of the project is 1% of the capital cost. Capital cost of the gas turbine $1000/kW, Annual O&M is 5% of the capital cost, while the salvage value at the end of the project is 1% of the capital cost. Assume that both plants life is of 20 years. The discount rate is assumed to be 5%. The electricity is sold at 20 c/kWh. Compare the two plants in terms of:

a) Annual energy production, AEP (MWh, no decimal) b) Full load hours (hours, no decimal) c) Present worth ($, no decimal) d) discounted pay back period (years, 1 decimal) e) Internal rate of return (%, 1 decimal) f) Levelized cost of electricity (c/kWh, 2 decimal)

g) annual CO2 emission (tons, no decimal). 6 2 Quiz:
