Subject: Pueblo

Bill,

Yesterday, we decided to look at two options for Pueblo; a 60 MW case and a
140 MW case. 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.
