In order to match these outputs as closely as possible with available equipment, I made the following selections: Case 1 Equipment 3 X GE LM 2500 Gas Turbine Generators with Heat Recovery and 1 X 22 MW Steam Turbine Generator Output at 95 deg F & 5000 ft 67 MW Output at avg. conditions (60 deg F) 73.4 MW Heat Rate at avg. conditions 8170 Btu/kWh (HHV) Case 2 Equipment 3 X GE LM 6000 Gas Turbine Generators with Heat Recovery and 1 X 44 MW Steam Turbine Generator Output at 95 deg F & 5000 ft 130 MW Output at avg. conditions (60 deg F) 143.7 MW Heat Rate at avg. conditions 7900 Btu/kWh (HHV) There is a wide fluctuation in ambient temperature in Albuquerque and I sized the blocks based on 95 deg F but used the annual average output at 60 deg F for estimating power sales. I have attached files that show the build-up of the estimated EPC price for the plants. The required power prices are projected in a simple-minded economics file attached. The projections are based on: 70% debt financing at 10% rate. 10-year project and debt life. 8500 hours per year at average output (97% capacity factor). Gas at $4.40/MMBtu. The results turn out pretty much as anticipated. Even with the larger plant, we'd have to sell the power for over 6c/kWh.
