PROGRAM DETAILS
WHAT YOU GET
ComEd offers a separate rebate for energy storage systems installed alongside qualifying distributed generation. This storage rebate stacks with the DG Rebate (smart inverter rebate) — you can receive both. For commercial systems, the rebate is $250 per kWh of nameplate storage capacity.
For a 500 kW solar + 500 kWh storage project, the combined ComEd rebates total $250,000 ($125,000 DG + $125,000 storage) — before ITC, MACRS, or IL Shines are applied.
C&I REBATE RATE
$250/kWh
Based on nameplate storage capacity.
ELIGIBLE TECHNOLOGIES
Electrochemical, Thermal, or Electromechanical
Must be commercially available, fixed in place, and capable of absorbing, storing, and discharging energy.
STACK WITH DG REBATE
Yes- claim both
Storage rebate is separate from and additive to the solar DG rebate.
INTERCONNECTION
Behind-the-Meter or Separate Meter
Storage may be interconnected behind the customer's meter or behind its own dedicated meter.
C&I Rate Schedule
No change required
Unlike residential, C&I customers are NOT required to switch rate schedules to receive the rebate.
ASSOCIATED DG REQUIRED
Must Be Paired with Solar (or Other DG)
The storage rebate requires an associated qualifying distributed generation facility — standalone storage does not qualify.
OUR ROLE
HOW GEC HELPS
GEC designs and installs solar-plus-storage systems and handles rebate applications for both components.
Battery system sizing based on your load profile and objectives
Combined DG + storage rebate application
Interconnection coordination for hybrid solar-storage systems
Guidance on Multi-Year Integrated Grid Plan participation requirements
IL Shines contract review and execution support
ITC documentation for storage (storage qualifies for ITC when charged primarily from solar)
WHO QUALIFIES
ELIGIBILITY REQUIREMENTS
Must be a current ComEd delivery service customer
Storage must be associated with a qualifying distributed generation facility (solar, wind, etc.)
Commercially available technology capable of absorbing, storing, and discharging energy
May be interconnected behind the customer's meter or behind its own meter
Must be fixed in place (not mobile)
DG Rebate application is not required to receive the storage rebate (though most projects claim both)
For commercial and industrial customers who take the storage rebate, you will be required to participate in one or more programs offered through ComEd's Multi-Year Integrated Grid Plan — typically a peak load reduction or demand response program. Program details are still being developed by ComEd. GEC will provide updates as program rules are finalized.

COMMON QUESTIONS
FREQUENTLY ASKED QUESTIONS
No. The storage rebate requires the battery to be associated with a qualifying distributed generation facility. For most commercial projects, this means solar PV.
Utility rebates generally do not reduce ITC basis. Storage systems charged primarily from solar qualify for the same ITC rate as the solar system. Consult your tax advisor for project-specific guidance.
ComEd is still developing the specific requirements for C&I customers who take the storage rebate. Generally, you should expect to participate in grid support programs that may require battery discharge during peak events. GEC will provide updates as program details are finalized.
Yes, if the existing solar system qualifies as a distributed generation facility. However, the solar system itself must have been interconnected after August 11, 2022 to qualify for the DG Rebate. Contact GEC to evaluate retrofit options.
The storage must be associated with a DG facility not exceeding 5,000 kW. There is no separate kWh limit specified for the storage component.
