C-PACE is a financing program that provides long-term, fixed-rate financing to building owners for renewable energy, energy efficiency, water efficiency, and resiliency projects. C-PACE is secured through an assessment lien on the property and is repaid over time as a line item on the property tax bill. If the building changes ownership during the payback period, C-PACE does not accelerate or become due. Rather, payments transfer to the new owner. Building owners work directly with private sector lenders to provide up-front costs for projects.

ComEd and Nicor Gas, customers are eligible to receive loans up to $150,000 for energy efficiency projects in their buildings. The loan is repaid through an additional charge on the customer’s utility bill. Loans can be paid over 1-10 years with a fixed interest rate. There is no penalty for early payment.

ComEd customers that operate smaller businesses and facilities (peak demand under 400 kW) are eligible for incentives on energy-saving projects in their buildings. Building owners can submit an interest form and get matched with a ComEd-approved Service Provider that will complete an energy assessment, compile a list of recommendations, and coordinate project delivery. The Service Provider can also apply ComEd incentives to bring project costs down. The program applies to existing buildings looking to pursue energy efficiency upgrades.

Nicor offers multiple resources for customers looking to complete energy efficiency projects. Businesses can receive free assessments and products, rebates for select energy efficiency projects, and custom incentives for projects that do not fall under the standard list of rebates. Nicor’s Emerging Technology program also seeks to bring new energy efficient technology into the market.

The Peoples Gas Energy Efficiency Program offers incentives for commercial customers to reduce energy consumption through efficiency improvements to their systems and equipment. The program supports commercial, industrial, and small and midsize businesses.

The SBA 504 Green Loan program is designed to assist small businesses for the acquisition of commercial real estate and heavy machinery/equipment. The SBA 504 loan program can also be used to refinance certain qualifying fixed-asset debt, providing an additional opportunity for small businesses to take advantage of the long-term, fixed-rate financing of the program. The program, updated in April 2024, now has no cap on the total project size and offers loans up to $5.5 million per project. To qualify, businesses must either reduce energy consumption by 10%, generate 15% renewable energy, or use sustainable design. These loans support energy upgrades while helping businesses save on long-term energy costs and contribute to environmental sustainability.

The Grant provides  seed funding and pre-development funding to equity eligible contractors to support energy efficiency (EE) and renewable energy (RE) projects.

This program is designed to empower small businesses by improving access to capital, particularly in markets that have historically been underserved or subjected to discrimination. It places a strong emphasis on providing targeted support to Socially and Economically Disadvantaged Communities and Individuals (SEDI) and Very Small Businesses (VSB). Additionally, the program contributes to the Climate Bank Finance’s Participation Loan Program, further enhancing its capacity to address critical funding gaps and promote equitable economic growth.

The Energy Efficiency Assessment Program provides funding to public housing authorities, local governments, or nonprofit organizations to conduct energy efficiency assessments at properties benefiting residents receiving housing assistance from a state or federal program.

A professional energy assessor or auditor conducts a site inspection and evaluates the residence to identify energy equipment, structural, and behavioral inefficiencies. Examples of recommendations found in the final report from an energy efficiency assessment can include installing programmable thermostats, adding insulation, or upgrading lighting fixtures. 

The Energy Efficiency Trust Fund was established to benefit residential electric customers through projects determined to promote energy efficiency in the State of Illinois, with an emphasis on low-income households. The Illinois EPA Office of Energy will award funds for energy efficiency projects at properties benefitting residents receiving housing assistance from state and federal programs.

The IEPA Office of Energy has released a Notice of Funding Opportunity (NOFO) expanding eligibility for this program from single family residences to multifamily properties of up to 20 dwelling units and eliminating the requirement of location in an environmental justice area of concern. Upgrades must have been identified in an energy efficiency assessment conducted within the last 5 years.
