Utilities in the Chicago area

Utility efficiency programs follow the company that delivers your power or gas, so check your bill before you book anything.

Electric

  • ComEd (Commonwealth Edison) Electric delivery for the City of Chicago and most of northern Illinois (ComEd says it delivers energy 'for over 9 million people in northern Illinois'). Its efficiency programs are open only to ComEd residential delivery customers. Source ↗
  • NIPSCO (Northern Indiana Public Service Co.) Electric and gas utility for northern Indiana, which covers the metro's Indiana side (Lake, Porter, Jasper and Newton counties). Service boundaries were not checked county by county. Source ↗

Natural gas

  • Peoples Gas City of Chicago. The rebate application says the program 'serves Peoples Gas customers in the city of Chicago'. Source ↗
  • North Shore Gas The '54 communities between Winnetka and the Illinois-Wisconsin border'. It shares rebate programs with Peoples Gas. Source ↗
  • Nicor Gas 'Most of the northern third of Illinois, excluding the city of Chicago', which means most Illinois suburbs in the metro. Source ↗

Chicago homes pair ComEd (electric) with Peoples Gas (gas). Most Illinois suburbs pair ComEd with Nicor Gas, and the north-shore suburbs pair ComEd with North Shore Gas. Some suburbs buy power from municipal or cooperative utilities, which ComEd and Nicor programs don't cover. Illinois EPA's Residential Electrification Catalyst Grant is aimed at those 'municipal and cooperative utility service areas', but only through weatherization agencies. The Indiana counties are served by NIPSCO.

How to get a home energy audit in Chicago

Home Energy Savings in-home assessment (ComEd with Nicor Gas, Peoples Gas and North Shore Gas)

ComEd Energy Efficiency Program, jointly with Nicor Gas, Peoples Gas and North Shore Gas

Open Open to income-eligible customers (at or below 80% AMI) as of 2026-10-12. ComEd says program details are 'subject to change or cancellation due to funding limits'.
Free Income-qualified

Official page ↗ · verified October 12, 2026

Who qualifies
ComEd residential delivery customers in single-family homes, two-flats, condos, mobile or manufactured homes and townhomes. Renters need the landlord's permission. Total household income must be at or below 80% of area median income. ComEd's limits for most of the Chicago metro are $67,150 for 1 person, $76,750 for 2, $86,350 for 3, $95,900 for 4, $103,600 for 5, $111,250 for 6, $118,950 for 7 and $126,600 for 8. Homes without gas service can still take part. Market-rate households can't get the in-home visit; they can do the online self-assessment described below.
What you get
A 60-90 minute in-person walkthrough by a ComEd-authorized energy advisor. ComEd says it is 'a visual walkthrough only – no diagnostic testing is performed'. Free installed products may include LEDs, a programmable or ENERGY STAR smart thermostat, WaterSense showerheads and aerators, hot-water pipe insulation and door sweeps. Advanced power strips, smart sockets and air filters can follow for self-install. You get a personalized report. Households that would benefit most may then get a separate 3-4 hour weatherization assessment (thermal imaging, blower door and combustion safety testing) and free insulation and air sealing, or a referral to IHWAP.

Federal Home Energy Rebates in Illinois and Indiana

The two federal rebate programs, HOMES (whole-home efficiency) and the high-efficiency electric home rebates (HEAR, renamed HEEHR in 2026), are run by each state, so availability depends on the state. DOE rewrote the rules effective May 29, 2026 (Program Notice 26-2 ↗): no more federal rebates for switching from gas, oil or propane to electric equipment, and insulation and air sealing come before heating and cooling upgrades unless a home already meets a state-set level.

Status for the Chicago metro
Not open yet not launched (as of 2026-10-12). Illinois HOMES pilot 'pending USDOE approval'; HEAR application 'has not yet been processed by USDOE'. Indiana side of the metro: open (Indiana Energy Saver Program, launched 2025-05-14). Official page ↗ verified October 12, 2026

Program: Illinois Home Energy Rebate Programs: Home Efficiency Rebates (HOMES, IRA Section 50121) and Home Electrification and Appliance Rebates (HEAR, Section 50122)

Run by: Illinois EPA Office of Energy. HOMES is to be run by the Illinois Department of Commerce and Economic Opportunity (DCEO).

Illinois was allocated $263 million and neither program has launched as of 2026-10-12. On HOMES, Illinois EPA says it 'intends to launch a pilot... with two Local Administering Agencies' and 'The program launch is pending USDOE approval.' On HEAR, the application 'has not yet been processed by USDOE or provided to Illinois EPA for administration or distribution.' Illinois plans to put 100% of rebate funds toward households below 80% AMI at first, with at least 10% for low-income multifamily. It will not pay retroactive rebates. The page gives no launch date or rebate amounts. On the Indiana side of the metro, the Indiana Energy Saver Program (HOMES and HEAR, about $182 million, run by the Indiana Office of Energy Development) launched May 14, 2025, and its official pages show applications open (indianaenergysaver.com).

Help for lower-income households

Illinois Home Weatherization Assistance Program (IHWAP), delivered in Cook County by CEDA

Illinois DCEO (statewide). CEDA (Community and Economic Development Association of Cook County) delivers it locally.

Free weatherization: air sealing, insulation, heating repair or replacement and ventilation (windows usually not eligible), up to $20,000 per home. Household income must be at or below 200% of the federal poverty level. CEDA serves owner-occupied buildings of up to four units that are structurally sound and haven't had IHWAP in the last 15 years. Elderly, disabled and young-child households get priority. Apply through DCEO's online pre-application, by calling 1-800-571-2332, or at a CEDA partner intake site. Peoples Gas (the City of Chicago's gas utility) sends customers to CEDA for weatherization. DCEO's directory sends 'Cook County (Outside of Chicago)' to CEDA, and 'Chicago only' to the City's Department of Family and Support Services, which lists only CSBG services. Collar-county agencies on DCEO's list include DuPage County Department of Community Services, Will County Center for Community Concerns, Community Action Partnership of Lake County, McHenry County Housing Authority, Kendall-Grundy Community Action and Family Services Agency of DeKalb County.

Who it applies to Large buildings only: existing commercial, institutional and residential buildings over 50,000 sq ft. It does not affect ordinary homeowners.

Owners benchmark whole-building energy use in ENERGY STAR Portfolio Manager every year, report to the City by June 1, and have the data verified by a credentialed professional every three years.

Proposed · not in force

Clean and Affordable Buildings Ordinance (proposed)

Who it applies to New construction only, as proposed. It does not cover existing homes.

Introduced January 24, 2024 to set an emissions standard that would push most new buildings to all-electric. It was sent to the Rules Committee. I couldn't find an official source confirming it passed. Treat it as pending or unverified, not as a rule homeowners must follow.

Notes worth knowing

  • The free utility in-home assessment in ComEd territory is now income-qualified (80% AMI or less).
  • Market-rate Chicago-area homeowners get only the online self-assessment and kit, so a diagnostic (blower door) audit means paying a private auditor.
  • Nicor itself says an energy audit 'may cost between $100 and $500 or more'.
  • ComEd's on-bill financing stops taking new applications about October 15, 2026 and closes to new customers January 1, 2027.
  • ComEd Whole Home Electric funding for gas-heated homes is fully allocated for 2026.
  • Illinois has not launched its IRA HOMES or HEAR rebates (pending USDOE).
  • Green Homes Chicago registration closed February 27, 2026.
  • Some partner pages (Chicago Bungalow Association, Indiana OED) still describe the federal credits as available.

Can I claim a federal tax credit for an energy audit in Chicago?

Not for an audit done in 2026.

Public Law 119-21 ended 25C and the Residential Clean Energy Credit (25D) for 2026 work. An audit done in 2025 is claimed on the 2025 return (Form 5695).
