7. Proposed Mechanical System CHP system Feasibility Check Spark Spread = Electricity rate – Gas rate =$11.29/MMBtu System may be inefficient Spark Spread was lower than $12/MMBtu Building does not run 24/7 Project Background Existing Mechanical System Proposed Mechanical System CHP System GSHP System Acoustical Breadth Cost Estimation Conclusion Presentation Outline Electricity – Northeastern Utilities suppliers provide electricity rate of 0.09051/kWh to commercial buildings. Electricity rate =(0.09051/kWh) * (1 kWh / 0.003412 MMBtu) = $26.53/MMBtu Natural gas – Natural gas price was adjusted by the government and it is 14.81 dollar/ 1000 cubic feet. Natural gas rate = 14.81 dollar/ 1000 cubic feet *1.029 = $15.24/ MMBtu Spark Spread = electricity rate – natural gas rate =$26.53/ MMBtu – $15.24/ MMBtu = $11.29/ MMBtu
