Combined heat and power

Recycle waste heat and generate power on-site.

What is CHP?

CHP, also known as cogeneration, describes a suite of technologies that can use a variety of fuels to generate both electricity and usable thermal energy (heat). This proven technology has been utilized for more than 30 years, often by commercial and industrial facilities with demand for both electricity and heat.

Benefits of CHP

CHP systems offer your facility an innovative way to:

  • Save energy
  • Lower costs
  • Help the environment

CHP systems help facilities turn typically wasted heat into useful electricity and thermal energy, which can be used for:

  • Space heating
  • Cooling
  • Domestic hot water heating
  • Dehumidification
  • Process heating

Available Rebates and Incentives

  1. Rebates: Combined Heat and Power (CHP) rebates depend on the amount of natural gas savings each system produces. Gas savings are calculated using the methodology outlined in the Illinois Technical Reference Manual (TRM).
    Customer sector Rebate
    Private sector $1/therm ($10/MMBtu) up to $500,000*
    Public sector $2.5/therm ($25/MMBtu) up to $500,000*

    *Rebates may not exceed 50% of the total project cost

  2. Engineering study incentives: We provide up to $15,000 to offset the cost of on-site engineering support to perform a feasibility study, investment-grade audit or process evaluation. Refer to the engineering study application for instructions on how to apply. All applications must receive preapproval before the study begins.

How do I get started?

Schedule an appointment with one of our energy advisors by contacting us online or calling 855-849-8928 and ask for the CHP program.

What are other ways my business can save energy and money?

Commercial and industrial customers can earn prescriptive rebates when they install qualifying steam traps; pipe, valve and fitting insulation; boiler reset controls; demand-controlled ventilation; commercial kitchen equipment; and other energy-saving items.
