CHP Resource Center

  • What is Combined Heat and Power (CHP)?

    CHP is an energy efficient technology that generates electricity and captures the heat that would otherwise be wasted to provide useful thermal energy.

    Learn the basics.

  • The CHP Energy and Emissions Savings Calculator

    The CHP Energy and Emissions Savings Calculator is a Microsoft Excel-based tool that calculates and compares the estimated fuel consumption and air pollutant emissions (CO2e, SO2 and NOX) of a CHP system and comparable separate heat and power system (e.g., grid power and a boiler system).

  • Could CHP be Right for Your Facility?

    View a list of questions to assess if your facility is a good candidate for CHP

EPA promotes greater use of combined heat and power (CHP) where cost-effective emissions reductions can be achieved by increasing the efficiency of the nation's energy supply. CHP also enhances the resiliency of commercial, industrial, and government facilities and supports renewable integration and electricity dispatch flexibility.
