Five years ago, an 80 MW gas power unit cost $150,000. The cost index for the turbine 5 years ago was 180 and it is now 196. The cost capacity factor is 0.7.
a. The plant engineering staff is considering a 100 MW unit of the same design to power a small isolated plant. Assume we want to add an additional compressor, which (when isolated and estimated separately) currently costs $25,000. Determine the total cost of the 100 MW unit.
b. Estimate the cost of a 50 MW unit of the same general design. Include the cost of the $25,000 compressors.
