Six years ago, an 80-kW diesel electric set cost $160,000. The cost index for this class of equipment six years ago was 187 and is now 194. The cost-capacity factor is 0.6.
a. The plant engineering staff is considering a 120-kW unit of the same general design to power a small isolated plant.
Assume we want to add a pre-compressor, which (when isolated and estimated separately) currently costs $18,000. Determine the total cost of the 120-kW unit.
b. Estimate the cost of a 40-kW unit of the same general design. Include the cost of the $18,000 pre-compressor.
a. Total Cost = $229, 707
b. Total Cost = $127, 512
