Combined Heat & Power – CHP Calculator Tool
A Simple ROI Analysis Calculator for CHP Technology
This ROI calculator provides a simple payback calculation for various CHP technologies based on the size and energy rates. The calculations use average pricing, efficiencies, & maintenance costs provided in the CHP Technology Catalogs available from the Combined Heat and Power partnership of the EPA. This calculator also shows the carbon emissions reductions from a CHP system based off of eGRID data.
The results produced by use of this tool are intended solely as a preliminary evaluation of a potential CHP installation. For a more detailed and exact evaluation, you should seek the assistance of a qualified engineering firm with input from the appropriate manufacturers of power generation equipment.

|CHP Technology||Reciprocating Engine||Micro Turbine||Gas Turbine||Fuel Cell|
|Typical Size Range||65 kW - 15 MW||30 kW - 2000 kW||1 MW - 50 MW||200 - 2000 kW|
|Average Installed cost ($/kW)||$ 1,433 - $ 2,900||$ 2,500 - $4,300||$ 1,250 - $ 3,300||$ 4,600 - $ 10,000|
|Total Average CHP System Efficiency||78.4%||66.8%||69%||82%|
|O&M Cost ($/kWH)||$ 0.0177||$ 0.013||$ 0.0111||$ 0.040|
|Notes:||Less than a 65KW Engine is considered Micro-CHP||Can package multiple Micro turbines to reach 2 MW||Size starts at 1000KW||MCFC & PAFC|
