Battery storage
Batteries that keep the lights on in an outage and shave the peaks your tariff charges for — with ComEd's storage rebate filed, and its virtual power plant terms modeled before you sign.
What we do
- Size the battery against your interval data or your bills — backup hours for the circuits you nominate, or peak shaving against the demand charge.
- Pair it with new or existing solar, or install it on its own: under ComEd's current terms a battery interconnected on or after 1 June 2026 no longer has to sit behind a solar array to qualify.
- Smart-inverter interconnection with ComEd — the application, the required inverter settings and permission to operate.
- Transfer equipment and critical-load panels, so the battery picks up the loads that matter when the grid drops.
- File the DG Rebate and walk you through the virtual power plant commitment that comes with it.
Who performs it
Private commercial storage runs with our renewable-energy team at Gullen Energy; public-agency systems run union with Boyd Electric; home systems are installed by licensed, insured and bonded technicians. The rebate filing and the interconnection paperwork stay with us.
Batteries change the electrical service, so we check the panel and the service size in the same site walk — see electrical upgrades.
How it's funded
ComEd pays per kilowatt-hour of battery — in exchange for a seat in its virtual power plant.
ComEd's DG Rebate terms set "$300/kWh of nameplate capacity of an energy storage facility" for customers in the residential or Under 100 kW demand classes. The battery must connect through a smart inverter that adheres to the settings in Rider DG Rebate, and the total rated capacity cannot exceed 5,000 kW. Rebates may be taxable.
For commercial customers outside the Under 100 kW demand class, and for community supply, the same terms set "$250/kWh of nameplate capacity of an energy storage facility." A paired system does not have to claim the solar rebate to claim the storage rebate.
"The retail customer associated with a qualified energy storage facility must agree to participate in ComEd's Scheduled Dispatch Virtual Power Plant (SDVPP) Program for the required SDVPP term, in order for such energy storage facility to qualify for a rebate. The SDVPP Program, offered under Rider SDVPP, is anticipated to go into effect March 1, 2027." In plain terms: ComEd may dispatch the battery on scheduled events for the length of that term, which affects how much backup you hold in reserve. We model that before you sign.
A separate ComEd rebate for paired solar and storage, "only available to projects with an energy storage facility with a nameplate capacity of 100 kW or more that participate in the PJM frequency regulation market." It applies to large commercial and utility-scale batteries, not to a home or a small business.
For commercial, industrial and multifamily property in a designated PACE area, IFA C-PACE "permits terms of up to 40 years, and allows financing of up to 100% of all project and closing costs" — "in each case up to 25% of the value of the property." Eligible improvements include energy and resiliency upgrades, and repayment is a special assessment on the property tax bill.
Commercial storage can also qualify for the federal §48E clean electricity investment credit; eligibility and timing depend on when construction begins, so we confirm it with your tax advisor rather than quote it here. The residential federal credit (§25D) is not available for property placed in service after 31 December 2025.
Pre-approval comes before the purchase order. Utility programs do not pay retroactively; we file first, then we build.
