Illinois C-PACE Financing
Grantya researchSee program
Illinois C-PACE (Public Act 99-0434, 2016) finances commercial clean energy and efficiency projects through a property-tax assessment — no upfront capital, off-balance-sheet, up to 100% of project and closing costs, repaid over the useful life of the measures. The primary statewide administrator is the Illinois Energy Conservation Authority NFP (IECA, https://iecapace.org); the Illinois Finance Authority (IFA) runs a parallel statewide program with terms up to 40 years, but the IFA assessment is capped at 25% of property value. Engage the program administrator (not a capital provider) to size and place the assessment. Typically stacks with the 48E ITC, Illinois Shines, and utility rebates.

- Notes
- Administrator by jurisdiction (verified 2026-06-01): IECA (iecapace.org) administers most opted-in counties including Kane, Cook, DuPage, Will, Lake, McHenry, and Kankakee. Kane was the first C-PACE program in Illinois (2019) — do not tell Kane-County clients to "verify" participation; tell them to engage IECA as the administrator. IFA runs a parallel statewide program (contact bfletcher@il-fa.com), terms up to 40 years but capped at 25% of property value. Chicago is a separate city program (see chicago_cpace). PACE Loan Group and Inland are capital providers/aggregators, NOT the program administrator. PACE financing is repaid (not a grant); it removes the upfront capital barrier. Confirm the governing program and cap before sizing.
