ComEd Distributed Generation Solar + Battery Rebate (Adjacent Capital — NOT a grant incentive)

Utility$300/kW (≤100 kW) or $250/kW (>100 kW) upfront; stacks with IL Shines RECs + federal ITC
What it is

ComEd pays an upfront one-time rebate for solar installations: $300 per kW DC for systems up to 100 kW and $250 per kW DC for systems above 100 kW. A 50 kW rooftop commercial system yields approximately $15,000 upfront. Battery storage rebates ($250/kWh) are available but specific terms for standalone storage require direct ComEd verification. Stackable with Illinois Shines REC payments (IPA program) and federal ITC (§48E).

Where it applies

ComEd Distributed Generation Solar + Battery Rebate (Adjacent Capital — NOT a grant incentive) is administered at the utility level. Depending on the program, eligibility may depend on the specific location, property type, or business activity rather than a single drawn boundary.

Boundaries are precise and change over time, so whether a specific address falls inside a mapped zone always depends on that exact address. The fastest way to check is to run a free snapshot for the parcel you have in mind — mapped coverage is a location signal, not an eligibility determination.
