ComEd - Distributed Generation and Storage Rebates
Administered by Commonwealth Edison
If you install solar or energy storage on your home or small business (under 100 kW), ComEd rebates you $300 per kW for solar and an additional $300 per kW if you add battery storage. To receive the rebate, you'll accept a lower credit rate for any excess electricity your system sends to the grid, matching rates available to community solar subscribers. If you only add storage without solar, you can skip the lower credit rate requirement.
Residential and small commercial customers under 100 kW qualify for $300/kW rebates on solar installations, with an additional $300/kW available for paired energy storage systems. Larger systems and community solar installations receive $250/kW (with $250/kW additional for storage). Customers receiving distributed generation rebates must accept net metering at the community solar credit rate, though storage-only rebates don't trigger this requirement. ComEd recently expanded eligibility to stand-alone energy storage systems under Public Act 104-458.
ComEd administers rebates for distributed solar and battery storage across residential, commercial, industrial, and federal sectors, with differentiated rates: $300/kW (plus $300/kW storage) for residential and under-100-kW demand customers, and $250/kW (plus $250/kW storage) for larger systems and community solar. Public Act 104-458 (2026) expanded stand-alone energy storage eligibility and requires ComEd to file tariffs within 120 days to provide additional compensation for grid services when customers participate in frequency regulation markets, reimbursing interconnection and software costs. Rebate recipients on distributed generation must move to the lower community solar net metering credit rate; storage-only rebate recipients may opt out of this rate change.

Program summary
As required by Illinois law, Commonwealth Edison offers rebates for distributed generation installation. Rebates are available as follows:
- For systems not owned by Residential or Under 100 kW Demand Class, or for Community Solar systems, the available rebate is $250 per kW
- For these customers, an additional rebate of $250 per kW is available for installation of energy storage systems
- For systems owned by Residential or Under 100 kW Demand Class customers, the available rebate is $300 per kW
- For these customers, an additional rebate of $300 per kW is available for installation of energy storage systems
Public Act 104-458 (2026) modifies the requirements to apply to stand-alone energy storage (previously, only storage associated with solar was eligible). The law added further requirements to existing language delineating that electric utilities with over 300,000 customers must provide additional compensation for distribution grid services. Upon proof of participation in the frequency regulation market, the customer will be entitled to a rebate equal to the cost of the interconnection facilities paid to ComEd, plus the cost of software, telecommunications hardware, and telemetry paid to enable participation. The utility must file tariffs in accordance with these requirements within 120 days of the law's effective date.
Receipt of a distributed generation rebate requires customers to receive a lower credit rate for net-metered electricity; the credit rate is the same as that received by community solar subscribers, including the energy supply, capacity, and transmission values but not delivery service charges. Receipt of a rebate for energy storage installation (but not the distributed generation installation) does not require net metering customers to move to the lower credit rate.Contact & resources
