The takeaway message is that there is* a 4-month delivery for a heating system <http://ecat.com/ecat-products/ecat-1-mw/ecat-1mw-technical-data> that has a lower levelized cost per thermal unit, including O&M, Fuel and 10 year straight line depreciation, than current natural gas price per thermal unit alone.
1dollar/MWh+1dollar/MWh+((1.5e6dollar/10year)/1MW)?dollar/1e6btu<http://www.testardi.com/rich/calchemy2/> ([{1 * dollar} / {mega*Wh}] + [{1 * dollar} / {mega*Wh}]) + ([{1.5E6 * dollar} / {10 * year}] / [1 * {mega*watt}]) ? dollar / 1e6btu = 5.6045044 dollar/1e6btu Current natural gas price for commercial heating is $8.22/1e6btu<http://www.eia.gov/dnav/ng/ng_pri_sum_dcu_nus_m.htm> . The proximate significance of this would be that even if a commercial business immediately writes-off the sunk-cost of a heating system on the order of 1MW (3.4MMbtu/hour), it still makes sense to replace it immediately. *The meaning of “is” here must be qualified as follows: If you have $1.5M to place in escrow, you can have your engineers perform whatever non-destructive tests you like to certify the system.
