Using 50 units as the nth of a kind volume for both the microturbine subsystem and for the fuel cell related subsystem estimates include capital costs variable operating costs and replacement costs. Using MTI s proprietary Upgrades and Enhancements Financial Evaluation Program software and incorporating a industry recognized standards for Cost of Electricity COE calculation a wide variety of plant equipment operations and variable cost simulations were conducted to evaluate different scenarios for system configuration. Using the system described within Section 2 component costs were compiled and nth of a kind costs were estimated based upon volume manufacturing cost reductions technology innovations leading to lower material process and manufacturing costs and performance enhancement to component and system operations leading to lower cost components. Initial installation nth of a kind capital costs including a 10 installation charge were 454 850 for the 727kW system leading to a 625 kW capital cost. Nth of a kind microturbine subsystem costs were 85 000 and fuel cell subsystem costs accounted for the remaining 328 500 excluding the 10 installation charges in both cases . In addition to the initial capital costs a conservative approach to one-time fixed costs assuming non-depreciable capital costs was utilized to replace both subsystems in their entirety at the end of each subsystems assumed lifetime .
