Retrocommissioning and Combined Heat and Power


An engineer will complete a detailed study of your facility geared toward identifying no- and low-cost opportunities for operational improvements to your facility’s existing energy-using systems.

The free study includes:

  • An initial phone call to discuss your facility’s operations and needs
  • A walk-through by an engineer to identify RCx opportunities
  • A customized report detailing estimated low-cost energy savings, and incentives for each recommended project
  • Ongoing support as identified natural gas projects are implemented

A facility may only qualify for an RCx study if the facility has an annual natural gas usage of 150,000 therms or more, has an Energy Management System (EMS) with trending capabilities and a central heating system. You must be willing and able to commit to a capital investment of at least $5,000 towards RCx related measures. This commitment is in consideration for receiving a free, valuable study.

Incentive Amount

Incentive Cap

$0.10 Per Therm Saved

Incentives cannot exceed the total project cost

Incentives are based on the therms saved from energy efficiency projects.

Combined Heat & Power

Combined Heat and Power (CHP) is an innovative and efficient way to generate power and thermal energy from a single energy source. CHP systems provide at least a portion of a facility’s electricity and capture waste heat from hot exhaust gases for use in space heating, cooling, domestic hot water heating, dehumidification and/or process heating.

The installation of these energy-saving technologies may be eligible for Nicor Gas engineering support and incentives in the CHP program administered by the University of Illinois at Chicago’s Energy Resources Center, who will assess the eligibility of customers to participate in the CHP program. Qualified customers can receive a CHP Feasibility Study conducted by the Energy Resources Center that evaluates the technical and economic viability of multiple CHP scenarios.

Nicor Gas and ComEd will perform an interconnection analysis and Nicor Gas will work with customers to determine peak gas pressure and flow demand, infrastructure needed and the customer cost, if any.

Customers will then submit a pre-approval application to the Nicor Gas Energy Efficiency Program for the capital project, install and commission the CHP system, which will undergo verification to determine eligible therm savings.

For more information and to request a CHP feasibility study, contact Darin Davenport or Ben Campbell.
