ComEd - Distributed Generation and Storage Rebates

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 systemsFor systems owned by Residential or Under 100 kW Demand Class customers, the available rebate is $300 per kWFor these customers, an additional rebate of $300 per kW is available for installation of energy storage systemsPublic Act 104-458 (2026) modifies the requirements to apply to stand-alone energy storage (previously, only storage associated with storage 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.
