How much is the ComEd battery storage rebate?

The ComEd battery storage rebate pays $300 per kWh of nameplate capacity for residential and small commercial customers — a one-time check calculated purely on your battery's size, not its cost. A 10 kWh battery earns $3,000; a 20 kWh battery earns $6,000. Larger commercial and industrial systems (outside the residential/Small C&I class) receive $250/kWh instead.

That's the whole formula — nameplate battery capacity, in kWh, times the applicable rate — and state law holds the $300 residential rate through December 31, 2029. You don't have to also claim ComEd's separate $300/kW solar rebate to collect the storage rebate; the two are filed independently, though your solar system still has to qualify as an eligible distributed generation facility either way. (ComEd's separate Solar Paired With Storage rebate is aimed at large commercial systems, not homes.) What solar itself costs before either rebate comes off is on how much do solar panels cost in Illinois.

Typical residential sizes — your rebate = nameplate kWh × $300:

Thinking about more than one battery? The rebate scales the same way — nameplate kWh × $300, whatever the total. Here's what that looks like on the most common single battery size versus two of them:

Straight arithmetic on the published $300/kWh rate — not a quote, and not a guarantee your home can fit or interconnect two units. State law also caps the payment at 5 kWh of battery capacity for every 1 kW of the battery's participating power, so have your installer confirm the math on a two-unit setup. Two batteries can also mean a bigger annual payment from ComEd's virtual power plant — see how that program pays, battery by battery.

Who qualifies for the ComEd battery storage rebate?

Your battery must be paired with a qualifying solar (or other renewable) system, include a smart inverter installed and in operation, and be owned by the applicant or installed with the property owner's permission. Standalone battery storage — installed without solar — doesn't meet ComEd's definition of an eligible energy storage facility, so it isn't eligible on its own. And ComEd's rebate page states that DG rebates are available to customers who interconnected after August 11, 2022.

Already have solar? A battery added to an existing system can qualify, as long as that system counts as a qualifying distributed generation facility under ComEd's terms — interconnected after August 11, 2022, with a conforming smart inverter — and the battery meets the same inverter requirement. Confirm your interconnection date with ComEd before you buy the battery on the strength of the rebate. A battery added after June 1, 2026 also brings ComEd’s net-metering rate rule into play: what changed on September 14. The rebate tool below covers the add-on case in one read.

With a lease or solar power agreement (PPA), the provider owns the battery, so the rebate typically goes to the provider. That's part of how solar and a battery come with no upfront cost; ask how the rebate is reflected in your monthly payment or rate, the same way you'd ask an Illinois Shines Approved Vendor how REC value shows up in your contract price. How lease, PPA and purchase compare over the full term is on solar lease vs. buying in Illinois.

Want the short version for your specific situation? Jump to the 3-step rebate tool below — your size, your eligibility, and the two commitments in one read.

What does taking the rebate commit you to?

Two things, on two different clocks. Since June 1, 2026, ComEd's rebate page makes participation in its Scheduled Dispatch Virtual Power Plant (SDVPP) a condition of the DG Rebate — a five-year program term during which ComEd can call on your battery on summer weekday afternoons. Separately, the rebate's own terms require you to take supply under a Qualifying Utility Product for the life of the battery. Neither is a one-time decision like the check itself.

The date that decides which clock applies to you: a storage rebate received on or after June 1, 2026 makes SDVPP participation mandatory. A rebate paid before that date — or no rebate at all — leaves participation voluntary, and the rider's December 31 opt-out belongs to voluntary participants only. Nobody else spells this out, and it's the single most useful thing to know before you sign.

What ComEd hasn't published yet: a dollar figure for leaving early, what happens if you sell the house during the term, any enrollment cap, and how a dispatch works if the power goes out — the rider says nothing about outages or backup reserve. Until it does, get each of those answered in writing before you rely on the rebate. The full rider — dispatch rules, payment timing, who can opt out — is read line by line on the ComEd virtual power plant guide.

Is there a rate-plan requirement for the ComEd battery rebate?

Yes — ComEd requires storage-rebate recipients to enroll in a Qualifying Utility Product and stay on it for the life of the battery. It doesn't have to be hourly pricing. State law gives a rebated battery the choice of an hourly pricing program or a time-of-use rate, and ComEd's current tariff defines Qualifying Utility Products to include Hourly Pricing (Rate BESH), Time of Day Pricing (Rate BEST) and Delivery Time of Day pricing.

If you land on Rate BESH specifically, that's a bigger commitment than it sounds: your ComEd supply charge would move with wholesale prices hour to hour instead of the flat rate most customers are on, for as long as you keep the battery. If you also have solar, Hourly Pricing changes how your export credits get calculated too — see our net metering guide, or the full mechanics on our dedicated ComEd Hourly Pricing + solar page before you choose. If hour-to-hour prices worry you, the time-of-day options are the alternative: compare them on ComEd's pricing pages, expect a switch to take two to three billing cycles, and confirm your choice with ComEd in writing. Check the current price before you commit: ComEd’s fixed supply price is 10.103¢ per kWh from October 1, 2026 through May 2027, the benchmark to measure hourly and time-of-day pricing against. What the October reset changed. One thing this requirement is not: a rule of the virtual power plant. Rider SDVPP has no hourly-pricing rule of its own; the supply-product clock comes from the rebate terms. ComEd’s net-metering rider now adds a similar rule for batteries connected on or after June 1, 2026: what changed on September 14.

Can a rebated battery charge from the grid?

Yes, since September 14, 2026. ComEd rewrote its net-metering rider, Rider POGNM, so a battery paired with solar may charge from your panels, the grid or both. Before that, a net-metered battery could charge only from its own solar. The rebate itself hasn’t changed: it still requires the solar pairing.

The same rewrite added a rate rule of its own. Any battery connected on or after June 1, 2026 has to stay on an hourly or time-of-day supply plan, ComEd’s or a retail supplier’s, to keep net metering. It’s separate from the rebate’s life-of-battery supply condition, but ComEd’s Hourly Pricing or Time of Day Pricing satisfies both.

One more date matters if you’re weighing a battery without solar: from January 1, 2027, a battery that charges only from the grid becomes eligible for net-metering compensation under the same rate rule. It still doesn’t qualify for this rebate until the standalone-battery rebate’s tariffs are approved. The three ways to get a home battery in ComEd territory, side by side: solar + battery, battery only, or a supplier bundle. How ComEd credits what you export: ComEd net metering, explained. What stays on the bill either way: will I still get an electric bill after solar?

How do you apply, and how fast does ComEd have to pay?

You can apply as soon as your interconnection agreement is signed — state law lets a battery owner apply then and receive the rebate value in effect that day. The application is online, through ComEd's interconnection portal; installers usually file it, and customers can register too. Once the application is complete and the system is operating, ComEd's tariff gives it 60 days to pay. The steps, in order:

1. Before you sign anything, get the conditions in writing. Confirm the installer is an Illinois Shines Approved Vendor (five minutes, here's how), that the inverter conforms to ComEd's required smart-inverter settings, and that your contract states who receives the rebate, which Qualifying Utility Product you'll be enrolled in, and that SDVPP participation is required. What else to check in the quote. If you finance it, check the loan for dealer fees.
2. Sign the interconnection agreement — and apply. State law lets a battery owner apply the day the interconnection agreement is signed and receive the rebate value in effect that day, and ComEd's tariff holds it as long as the system has permission to operate within 24 months — worth knowing, since the law guarantees $300 only through 2029. The application is online, through ComEd's interconnection portal, which registers customers as well as contractors. Installers usually file it; ask for a copy. ComEd's terms require an itemized contractor invoice or purchase receipt with it.
3. Install, interconnect and pass inspection. The battery must be paired with a qualifying solar system; ComEd's rebate page states DG rebates are available to customers who interconnected after August 11, 2022. ComEd can inspect rebated equipment, and can ask for access to it and your project documents for up to a year after it pays.
4. The payment clock starts. ComEd's tariff gives it 60 days to pay once your application is complete, it has every document it asked for, and the system is operating in parallel with the grid. When the solar rebate is part of the same application, the tariff also waits on ComEd's notice to you about net metering. An incomplete application delays payment or gets it denied.
5. Receive the check — then keep the two commitments. Enroll in SDVPP when ComEd opens enrollment — it hadn't as of September 28, 2026 — and stay on your Qualifying Utility Product for the life of the battery. Keep your invoices and approvals on file.

Questions about a filed application go to ComEd's DG Rebate desk: [email protected] or (833) 688-7730, as listed on ComEd's rebate page on September 21, 2026.

What does taking the ComEd battery rebate cost you?

Five years of virtual-power-plant participation with the battery fixed in place, a Qualifying Utility Product for as long as the battery exists, and — according to ComEd's tariff — no Community Solar subscription at the same address. The good news: unlike the separate solar generation rebate, taking the storage rebate does not cost pre-2025 solar owners their full-retail net metering. And with a lease or PPA, the rebate typically goes to the company that owns the equipment, as part of the $0-upfront arrangement.

Weigh the two commitments as a pair, not as fine print. Ask what ComEd charges to leave the program early and what happens on a sale of the house — neither is published yet. Backup power mostly survives: dispatch only covers summer weekday afternoons, but the rider says nothing about outages, so ask your installer how much charge the battery will hold in reserve. Watch out, too, for offers that bundle a battery with a non-utility electricity-supply contract and get called a "rebate" or "free battery" — those are not this ComEd program and run on very different terms: what those contracts actually say. In fact there are now three distinct lanes to a home battery in ComEd territory — this rebated-and-net-metered lane, the supplier-bundle lane, and a standalone lane through the virtual power plant and, from January 1, 2027, net metering — each with its own rules on charging, credits and who gets paid: the three lanes, side by side. Not sure whether solar-paired storage fits your home? A two-minute eligibility check can model that against your own roof and usage before you talk to an installer.

Will a rebated battery back up your home in an outage?

Yes, if the system is built for it. A standard grid-tied solar system shuts off when the grid goes down; the Department of Energy notes that running a home without the grid takes solar paired with battery storage and an inverter designed for that job. Taking the rebate doesn’t change that.

The virtual power plant doesn’t take backup away either. Dispatch only covers 4 to 6 pm Central on summer weekdays, and Rider SDVPP says nothing about outages or backup reserve. How much charge the battery holds back is a setting you and your installer choose; holding more lowers your seasonal virtual-power-plant check but breaks no rule.

Before you sign, get three answers in writing: which circuits the battery will run in an outage, a few essentials or the whole home; how much charge it keeps in reserve during dispatch season; and how ComEd’s program handles a dispatch during an outage, which ComEd hasn’t published. Whether backup alone justifies a battery is its own question: is a home battery worth it in Illinois? For storms and snow, see how solar handles an Illinois winter.

Does the battery rebate stack with other Illinois incentives?

Yes. The storage rebate stacks with ComEd's separate $300/kW solar Distributed Generation rebate and with Illinois Shines renewable energy credits, which pay $80.77 per REC in ComEd territory for program year 2026–27 on systems up to 10 kW AC, plus $20 more per REC if you own the system outright. These are three distinct value streams on the same system, each with its own rules — see the full stack in one place on Illinois solar incentives 2026.

For the solar side of that math, see our ComEd Solar Rebate guide — this page covers storage only.

The virtual-power-plant payment is a fourth stream, and a different kind: it's a condition of this rebate, not a stacking bonus, and it pays $10 per kW-Season on what your battery actually delivers during dispatch hours — the ComEd Virtual Power Plant guide works the payment example through.

Ameren Illinois customer? Ameren pays the same $300 per kWh for homes under the same state law, but its conditions and paperwork are its own. Start with the Ameren virtual power plant guide, or see both utilities side by side on Illinois battery incentives, explained. Ameren also credits solar exports differently: Ameren net metering, explained.

What would the rebate mean for your home?

Three steps, answered from ComEd's own published terms: your battery size, the eligibility gates, and the two commitments. Nothing is sent until you choose to start the eligibility check — this runs in your browser.

The terms, in plain English

DG Rebate

ComEd's Distributed Generation Rebate — the umbrella program that pays both the $300/kW solar rebate and the $300/kWh storage rebate.

Nameplate capacity

The rated size of your equipment, in kW for solar or kWh for a battery, as stated by the manufacturer — this is what the rebate is calculated on, not what the system cost or what it's worth.

Scheduled Dispatch Virtual Power Plant (SDVPP)

ComEd's program, approved by the Illinois Commerce Commission on June 30, 2026, that pays enrolled battery owners $10 per kW-Season for energy sent to the grid on summer weekday afternoons. Participation is a condition of any storage rebate received on or after June 1, 2026.

Program Term and Season

The term is five consecutive Seasons; a Season runs June 1 to September 30. The dispatch window is 4–6 pm Central, Monday through Friday, during the Season. The battery must stay fixed in place for the whole term.

Qualifying Utility Product

The ComEd rate options that satisfy the storage rebate's life-of-battery requirement. ComEd's current tariff defines them to include Hourly Pricing (Rate BESH), Time of Day Pricing (Rate BEST) and Delivery Time of Day pricing.

Qualifying Supply Product

The net-metering rider's rate rule for batteries connected on or after June 1, 2026: ComEd's Hourly Pricing, its Time of Day Pricing, or a retail supplier's time-of-use product, kept for as long as you want net metering. Separate from the rebate's Qualifying Utility Product, though ComEd's hourly and time-of-day options satisfy both.

Rider POGNM

ComEd's net-metering tariff. The September 14, 2026 rewrite lets a solar-paired battery charge from the grid, adds the supply-product rule above, and makes a battery without solar eligible for net-metering compensation from January 1, 2027.

Rate BESH

ComEd's hourly-priced supply rate (Basic Electric Service Hourly) — one Qualifying Utility Product among others. On it, solar export credits are valued at hourly market prices and applied against the cost of your bill rather than supply alone; how that works.

Project Owner

Where a battery comes through a lease or a solar power agreement (PPA), the company that owns the equipment, and typically who the rebate is paid to. A battery bought with a loan belongs to you.

Community Solar

A subscription to a shared, off-site solar array rather than panels on your own roof. ComEd's terms treat this and the storage rebate as mutually exclusive.

ComEd Battery Storage Rebate FAQ

Does ComEd's battery rebate require solar panels?

Yes. ComEd's $300/kWh storage rebate only applies to battery systems paired with a qualifying renewable-generation facility — in practice, almost always solar. A standalone battery with no solar system attached doesn't meet ComEd's definition of an eligible energy storage facility. That's set to change: Illinois' 2025 grid law directs a standalone-battery rebate, which ComEd expects to apply to batteries interconnected on or after June 1, 2026, pending ICC-approved tariffs — until that approval, solar pairing is required.

Can I add a battery to solar I already have and still get the rebate?

Yes, if the existing system counts as a qualifying distributed generation facility under ComEd's terms. ComEd's rebate page states DG rebates are available to customers who interconnected after August 11, 2022, and both the solar system and the battery must use an inverter that conforms to ComEd's required smart-inverter settings. Confirm your interconnection date with ComEd before you buy the battery on the strength of the rebate.

How much does a typical home battery earn from the ComEd rebate?

The rebate is $300 per kWh of nameplate capacity, calculated on battery size, not battery cost. A 10 kWh battery earns $3,000; a 13.5 kWh battery (a common size class) earns $4,050; a 20 kWh battery earns $6,000. Two batteries earn roughly double, since the rebate simply scales with total nameplate kWh.

Is the ComEd battery rebate going down in 2030?

State law guarantees the $300 per kWh storage rate only through December 31, 2029. For 2030 onward, the only storage figure it names is $250 per kWh, for a stand-alone battery; it doesn't restate a rate for a battery paired with solar. Because the value locks when you apply at the signing of your interconnection agreement, a battery signed and applied for by the end of 2029 keeps $300 as long as it has permission to operate within 24 months, per ComEd's tariff.

Do I have to join ComEd's virtual power plant to get the battery rebate?

Yes, for any storage rebate received on or after June 1, 2026. ComEd's rebate page states the customer must agree to participate in its Scheduled Dispatch Virtual Power Plant for the required term — five consecutive Seasons of summer weekday dispatch, with the battery fixed in place. ComEd pays $10 per kW-Season for the energy you deliver. Rebates paid before June 1, 2026 didn't carry the requirement, and joining stays voluntary for anyone who never took the rebate.

Is ComEd's virtual power plant enrollment open yet?

Not as of September 28, 2026. The Illinois Commerce Commission approved Rider SDVPP on June 30, 2026, the tariff requires service to begin no later than March 1, 2027, and CUB reports ComEd is working toward a spring 2027 launch — but enrollment dates, any cap, and the process haven't been published. Taking the rebate now means agreeing to enroll when it opens; we re-check the day ComEd announces it.

Will my battery still back up my home in an outage if it's in ComEd's virtual power plant?

Most of the time, nothing changes. Rider SDVPP only counts what your battery sends to the grid from 4 to 6 pm Central on weekdays between June 1 and September 30, and it sets no minimum injection. It says nothing about outages or backup reserve. Because the payment is based on your average injection during those hours, holding more charge back for outages lowers your seasonal check rather than breaking a rule. ComEd hasn't published how a dispatch works if the power goes out, so ask your installer how the backup reserve will be set, and get ComEd's answer in writing.

What is a Qualifying Utility Product, and do I have to stay on it forever?

It's the ComEd rate option you must enroll in — and stay on for the life of your battery — to keep the storage rebate. ComEd's current tariff defines Qualifying Utility Products to include Hourly Pricing (Rate BESH), Time of Day Pricing (Rate BEST) and Delivery Time of Day pricing, and state law gives rebated batteries the choice of hourly or time-of-use pricing. Compare them against how your household uses power, and confirm your choice with ComEd in writing.

Can my rebated battery charge from the grid?

Yes, since September 14, 2026. ComEd rewrote its net-metering rider, Rider POGNM, so a battery paired with solar may charge from the panels, the grid or both. Before that, a net-metered battery could charge only from its own solar. The rebate itself still requires the solar pairing.

Do I need a special rate to keep net metering with a battery?

If the battery was connected on or after June 1, 2026, yes. ComEd's rewritten net-metering rider requires an hourly or time-of-day supply plan, from ComEd or a retail supplier, to stay on net metering. That's separate from the rebate's life-of-battery supply condition, though ComEd's Hourly Pricing or Time of Day Pricing satisfies both.

Can a battery without solar get net metering from ComEd?

Starting January 1, 2027. Under ComEd's rewritten rider, a battery with no solar that charges only from the grid becomes eligible for net-metering compensation that day, under the same hourly or time-of-day rate rule. This rebate is different: it still requires solar until the standalone-battery rebate's tariffs are approved.

What if I sell my house during the five-year virtual-power-plant term?

ComEd hasn't published what happens. The rider requires the battery to stay fixed in place for the whole program term, the December 31 opt-out applies to voluntary participants only, and no early-exit dollar figure or sale provision has been published. Get ComEd's answer in writing before you sign, and if a move inside five years is likely, weigh the rebate against that gap rather than assuming it transfers. What a sale means for the solar itself, and for your net metering, is covered in selling a house with solar in Illinois.

Will taking the battery rebate affect my net metering?

Not on its own. If you installed solar before January 1, 2025 and still have full-retail net metering, taking the storage rebate alone won't cost you that status. It's the separate solar generation rebate that ends full-retail netting — the storage rebate doesn't. Separately, since September 14, 2026 ComEd's net-metering rider requires an hourly or time-of-day supply plan for any battery connected on or after June 1, 2026, so confirm with ComEd how that applies to your account before you add one.

Can I get the battery rebate if I lease my battery or have a PPA?

Not directly. With a lease or solar power agreement (PPA), the provider owns the battery, so the rebate typically goes to the provider. That's part of how these offers come with no upfront cost; ask how the rebate is reflected in your monthly payment or rate.

Does the battery rebate come automatically with the solar $300/kW rebate?

No — they're filed as separate applications, and you don't have to claim the solar generation rebate to claim the storage rebate. Your underlying solar system still has to qualify as an eligible distributed generation facility either way.

When can I apply for the ComEd battery rebate?

As early as the day your interconnection agreement is signed. State law lets a battery owner apply then and receive the rebate value in effect that day, and ComEd's tariff holds it as long as the system has permission to operate within 24 months. The application is online, through ComEd's interconnection portal, which registers customers as well as contractors; installers usually file it.

How long does the ComEd battery rebate check take to arrive?

ComEd's tariff requires it to pay within 60 days once its conditions are met: a complete application, every document it asked for, and a system operating in parallel with the grid. When the solar rebate is part of the same application, the tariff also waits on ComEd's notice to you about net metering. An incomplete application delays payment or gets it denied.

Can I still get the battery rebate if I'm on a Community Solar plan?

No. According to ComEd's tariff, customers who receive a battery storage rebate can't also participate in a Community Solar subscription — it's one or the other, not both.

Is the ComEd battery rebate the same thing as Illinois Shines?

No — different programs, different payers. The battery rebate is a one-time payment direct from ComEd. Illinois Shines pays for renewable energy credits through your Approved Vendor, separately, over a 15-year contract. Many systems qualify for both.

Is the ComEd battery rebate taxable?

It may be. ComEd's 2026 rebate terms say rebates may be taxable under federal and state tax codes, and that a rebate over $600 will be reported to the IRS unless you show you're exempt — a typical $4,050 battery rebate clears that line. This isn't tax advice; ask your tax preparer how it applies to you.

Is there a federal tax credit for a home battery in 2026?

Not for a battery you buy. The residential clean energy credit (Section 25D), which covered home batteries of at least 3 kWh, ended for expenditures after December 31, 2025, and that holds for cash and loan purchases alike. A leased battery, or one installed under a service agreement with the company that owns it, can still carry a separate federal business credit, which the 2025 tax law left on a longer timeline for batteries than for solar, under stricter sourcing rules. The company that owns the equipment claims it, so ask whether a given offer still qualifies and whether its price reflects it. The full timeline is on did the solar tax credit end? Illinois has no state solar or battery tax credit either: does Illinois have a state solar tax credit?

What size battery gets the biggest ComEd rebate?

State law caps the storage payment at 5 kWh of battery capacity for every 1 kW of the battery's participating power, and at 25,000 kWh in total; projects with an interconnection agreement signed on or before June 1, 2026 are exempt. Within those limits the rebate scales with nameplate kWh at $300/kWh. A bigger battery, or a second one, earns a bigger one-time check, but it also means a bigger upfront system cost, so read the rebate as an offset, not a reason to oversize — and have your installer confirm the kWh-to-kW math on a large setup.
