Is a Free Home Battery Worth It When Backup Power Is Not Guaranteed?

A "free home battery" is a leased battery. The provider is the lessor and stays the owner; the equipment is bolted to your wall, wired into your panel, and it is still theirs. From that moment, everything you get out of it is whatever the lease agreement requires them to give you, not the retail price of the hardware, not what the salesperson said, not what the provider normally does. The lease. So whether you are in PSE&G territory or anywhere else in New Jersey, what decides whether your sump pump runs at 2 a.m. during a nor'easter is not the box on your wall. It is whether the lease requires usable energy to be in that box when the power fails.

Many homeowners think energy independence begins with having a battery installed, but ownership, operating control, and guaranteed stored energy determine whether it provides dependable protection. All three are decided on paper, not on the wall. A battery you do not own, cannot control, and are not promised any particular amount of stored energy from leaves you with no claim on anyone the night it is empty.

One distinction decides everything. A reserve target, an operating preference, and a best-efforts policy all describe what the lessor intends. A guarantee is a term the lessor must meet — measured in a defined way, at a defined time, with a consequence if it is missed. Sales language can use the first three in a tone that sounds like the fourth, and only the fourth is worth anything when the grid goes down.

These arrangements can be entirely legal and legitimate, they are disclosed in the lease, and for some New Jersey households the trade is a reasonable one. But run the arithmetic before you sign. If the lease gives you no ownership, no share of the grid revenue the battery earns, no claim on any incentive it may one day qualify for, no control over when it discharges, and no guaranteed backup, what substantial benefit is left on your side of the table? That is not an accusation. It is a valuation question, and the answer is sitting in the lease in front of you.

As of July 14, 2026: New Jersey has no open rebate or performance-incentive program that pays homeowners for a home battery — the Garden State Energy Storage Program's only open solicitation is limited to transmission-scale systems of at least 5 MW AC, and the distributed, behind-the-meter segment that would reach home batteries has not launched. The state also has no operating virtual power plant program; the Board of Public Utilities is still gathering stakeholder input. The federal Residential Clean Energy Credit (Section 25D) is no longer available for homeowner-owned property installed after December 31, 2025, while a business that owns a home battery may still be eligible for the commercial Clean Electricity Investment Credit. In a leased, provider-owned "free" battery program, what you receive is whatever the lease requires the provider to deliver — nothing more.

Free Home Battery Offers at a Glance

• Is a free battery really free? It may carry no upfront charge, but it is a lease — and you may be granting long-term ownership, operating, supplier, and property-access rights in exchange.
• Who qualifies? Any New Jersey homeowner a provider will sign — eligibility is set by the lease, not by a state program, because New Jersey has no open rebate or performance-incentive program that pays homeowners for a home battery today. (Two long-standing state tax exemptions do apply to home batteries, but neither is a cash rebate.)
• Timing: New Jersey's distributed storage incentive (Garden State Energy Storage Program, Phase 2) has not launched as of July 14, 2026, and no amounts are set — but a lease signed today may already assign any future incentive to the lessor, so ask in writing who would receive it.
• Federal credit status: The residential clean energy credit (Section 25D) is gone for homeowner-owned systems installed after December 31, 2025 — and it never applied to a leased battery in the first place, so under a lease you were never in the federal tax picture at all. The commercial credit still exists and follows whoever owns the equipment.
• Is backup guaranteed? Only if the lease states a measurable minimum reserve and a remedy. A reserve target is not a guarantee — assign it zero guaranteed value.
• Before you sign: Get written answers on who owns the battery, who holds dispatch rights, who the lease assigns any incentive or grid revenue to, and what the guaranteed backup reserve is.

What does "free" actually mean in a free home battery offer?

"Free" means no upfront charge. It does not mean the battery is yours. In these offers "free" describes the absence of an equipment bill, an installation bill, and a separate battery payment — not a transfer of title, not operating control, and not guaranteed backup power. The instrument is a lease, and you are the host site.

There is real substance on the "free" side: no upfront equipment payment, no installation charge, no separate monthly battery payment, and commonly lessor-paid maintenance while the program is active. What "free" may not mean is the list that decides the value of the deal:

• You receive ownership of the battery.
• Ownership ever transfers to you, at any point, at any price.
• You control when the battery charges or discharges.
• You receive any incentive, rebate, tax credit, or grid-program payment the system earns — the lease may assign every one of them to the lessor, including from programs that do not exist yet.
• You receive any virtual power plant (VPP), demand-response, or energy-arbitrage revenue the battery earns.
• Backup availability is guaranteed at any particular level.
• You can walk away without consequences.

That gap forces a reframe. The homeowner should not value the offer according to the retail price of the installed battery if the provider retains ownership. The homeowner is not necessarily receiving the asset; the provider may be locating its own revenue-producing equipment at the customer's property. Hosting is not owning.

Ownership matters here for exactly one reason: it is why the lessor holds all the definite rights and you hold only what the lease hands back. So value the program by what the lease obligates the lessor to deliver to you — never by the sticker price of the hardware on your wall.

Who gets what in a provider-owned home battery deal?

The lessor gets the definite rights; you get whatever the lease requires it to give you. On the lessor's side that may include ownership of the battery, long-term access to your property, remote dispatch rights, tax benefits, incentives, grid-program revenue, and a long-term retail-energy relationship. On yours: no upfront payment, plus whatever the lease expressly and measurably guarantees.

Read the table with one word in mind: may. Not every program includes every item, and a well-written lease can put real, enforceable benefits in your column. Hold your own lease up against it, clause by clause.

The question is not whether the lessor's column is long. It is whether your column is definite, measurable, and enforceable. Take each benefit you were told about and ask three things: does the lease require it, could you measure whether it was delivered, and does anything happen if it is not?

Almost everything in the lessor's column is a clause you can ask to read today — the term, site access, dispatch rights, transfer duties, the right to assign the lease to another company, and the clause that assigns the benefits. That last one deserves its own reading; the New Jersey incentives section later in this article shows you exactly what to look for and what to ask.

Stated at its sharpest, and stated fairly: the homeowner may assume definite, long-term obligations while receiving no comparably definite core benefit. It is a description of how the paperwork is shaped, and it is fixable — by written obligations in the lease, with remedies behind them.

Is backup power the entire consumer bargain in a free-battery program?

Often, yes. Take away ownership, incentives, VPP compensation, and operating control, and dependable backup is the only substantial reason left to sign. That makes a weak or non-guaranteed backup commitment a problem that goes to the heart of the deal rather than a minor limitation.

Nobody signs up for electricity-price arbitrage. They sign up for the outage: the food in the refrigerator, the water rising in the basement, the CPAP machine, the furnace that will not run without power to its controls. Backup is the product. If backup is the reason you signed and backup is the one thing the lease does not require, the lease has given you obligations in exchange for a hope.

Four things that are not the same

Most confusion in this market comes from collapsing four situations into one word. Keep them apart:

• Receiving a battery. Title passes to you. The equipment is yours, and so is everything it stores and everything it earns.
• Hosting somebody else's battery. The equipment is at your address but is not yours. You are the site for an asset another company owns, operates, and monetizes.
• Receiving occasional backup when energy happens to be available. Sometimes the battery is charged when the power fails; sometimes it is not. Nothing in the lease decides which.
• Receiving a contractually guaranteed amount of backup. The lease states a measurable minimum, when and how it is measured, a limit on discharging below it, and a remedy. This is the only one of the four you can plan around.

A sales conversation can describe the second and third situations in language that sounds like the first and fourth. Sort every promise into the right bucket before you sign — because afterward, the lease does the sorting for you.

When "usually available" is not enough

Backup power is an emergency-preparedness product, and preparedness has a different standard than convenience. Refrigeration for food and medication, a sump pump keeping a basement dry, medical equipment that runs overnight, heating controls, communications, a well pump — every one has a failure mode where "usually" is not a plan. In New Jersey the outages homeowners worry about arrive with coastal storms, nor'easters, and summer thunderstorms, the same weather that puts a sump pump to work. A sump pump that runs for an hour or two because that is all the energy that happened to be in the battery is not flood protection. It is a delay.

So set the standard clearly: a backup benefit that is a contingent possibility rather than an enforceable deliverable cannot be counted as protection. None of this says the battery will not provide backup — it very well may, and often. The claim is narrower and more durable: under a lease with no reserve obligation, backup cannot be relied on contractually, and a benefit you cannot enforce is a benefit you cannot price.

What is the zero-guaranteed-value test?

The zero-guaranteed-value test is one question: would you sign this same lease — same term, same supplier requirements, same operating restrictions, same transfer obligations, same provider control — if the battery held no usable energy during an outage? If the answer is no, the rule follows: assign zero value to every benefit the lessor is not contractually obligated to deliver.

You are not predicting that the battery will be empty. You are asking what your lease would be worth if it were. Run it as four steps, with the lease in front of you:

1. List every obligation you take on: the term, the ownership you never receive, the site access you grant, the dispatch rights the lessor holds, any supplier enrollment, any consent or transfer duties, and any cancellation or removal costs.
2. List every benefit the lease requires the lessor to deliver — in writing, in measurable terms, with a remedy attached if it is not delivered.
3. Cross out every benefit on that second list that is only a target, a preference, a policy, an expectation, or an estimate. If nothing happens when it is missed, it is not an obligation.
4. Ask whether what remains is worth what you signed in step one.

This is more accurate than declaring the battery worthless. Possible backup may have expected value, but it does not have guaranteed value — and a long-term lease is not priced on averages, it is enforced on terms. If a provider tells you the test is unfair, there is an answer that costs nothing when the program works as described: put the reserve in the lease, with a measurement method, a limit on discharging below it, and a remedy.

Key takeaway: Expected value is what you hope for. Guaranteed value is what you can enforce. Only the second one belongs on your side of the ledger.

Does a written backup guarantee make the battery failure-proof?

No. No contract can make hardware infallible, and even a battery you own outright can fail. What a real guarantee does is make failure contractually consequential: it sets a measurable obligation, limits discharge below the reserve, creates reporting duties, and provides a remedy.

Concede the honest point first. Inverters fail, communications drop, firmware misbehaves, and no clause in any lease prevents that. What a guarantee changes is not physics but who absorbs the loss when physics does not cooperate. Without an obligation, an empty battery at the start of an outage is an unfortunate outcome and you eat the cost. With one, it is a breach — and a breach comes with a remedy, a record, and a counterparty that has a reason to prevent a repeat.

What a meaningful backup provision must address

Do not read the brochure, and do not rely on the reserve slider in the app. Read the lease for these ten items. A provision that addresses all ten is a guarantee; one that addresses two or three is a set of good intentions with paperwork around it.

1. A minimum usable energy or state of charge. A number, not an adjective — the floor the system must hold for you.
2. When the reserve is measured. An unmeasured floor is not a floor.
3. Whether it applies during grid or VPP events. A reserve the lessor may discharge through is not protecting you when protection matters.
4. Protection before forecast emergencies. Does the system pre-charge when severe weather is forecast — and is that required by the lease or merely typical?
5. Your authority to increase the reserve. Not visibility, authority: can you raise the floor, and can the lessor lower it back?
6. Opt-out or override rights. Can you decline a dispatch, how much notice do you get, and are opt-outs limited or penalized?
7. Technical exceptions. Every real guarantee has carve-outs. Are they narrow, or wide enough to swallow the guarantee?
8. Restoration after a dispatch. How quickly must the battery be recharged to the reserve, and from what source?
9. Access to performance history. A promise you cannot audit is a promise you cannot enforce.
10. Compensation or termination rights for repeated failures. If nothing happens the third time the battery is empty, the first nine items have no teeth.

Items five through eight are where reserve mechanics, dispatch rights, and storm preparation get decided. The section below on who controls the battery before an outage covers them in depth — read it with this list in hand and your lease open.

Does "whole-home backup" mean dependable backup duration?

No. "Whole-home backup" tells you which loads the system is wired to energize, not how long it will run them. The inverter and wiring are sized to pick up the whole panel instead of a few protected circuits — an engineering advantage, not a promise about duration, and no statement at all about how much energy is in the battery when your lights go out.

Six things people confuse

A sales conversation collapses these six into one. Only one of them is enforceable, and only if your lease says so.

1. Maximum output, in kilowatts. What the system delivers at any instant.
2. Total usable energy, in kilowatt-hours. The size of the tank, not the speed of the tap.
3. Which loads are connected. Whole panel, a critical-loads subpanel, or something between.
4. State of charge when the outage begins. Not a specification — a fact, set by what the system was doing beforehand.
5. The guaranteed minimum reserve. The energy your lease requires to be held back for you. The only enforceable item on this list, and only if the lease agreement states it.
6. Expected runtime. The number you actually care about — derived from the four above, rarely stated on its own.

Approximate backup energy = usable battery capacity x available reserve, minus operating and conversion losses.

Capacity is fixed by the hardware. Losses are physics: round-trip efficiency is the share of stored electricity later retrieved, as the U.S. Energy Information Administration defines it, and about a tenth of the energy used to charge a home battery — typically somewhat more in practice — is lost to heat and conversion. Only the middle term moves, and whoever the lease puts in charge of the settings is the one who moves it. A partial reserve is not useless; a little stored energy still carries a refrigerator through a short outage. But a reserve that is not guaranteed in the lease, or that someone else may lower, is not emergency preparation.

Are no upfront cost, free installation, and included maintenance real homeowner benefits?

Only partly. Each one protects the lessor's revenue-producing equipment first, and each is worth something to you only where the lease agreement turns it into a measurable, enforceable obligation owed to you. Count them honestly, one at a time.

No upfront equipment payment

No upfront payment may simply mean the lessor financed and owns the asset it plans to operate and monetize. The absence of a bill tells you that you were not charged; it does not tell you anything was given to you. Ask what you hand over instead: a long term, property access, an interconnection at your meter, the operating rights that let the system earn money, and possibly your electricity-supply business.

Installation included

Installation has customer value only to the extent that the installed system delivers a meaningful and enforceable customer benefit. A lessor earns nothing until its battery is mounted, wired, permitted, inspected, and interconnected at somebody's house — so installation is a precondition of its business as much as a gift to you. A properly permitted job is worth having. It is not proof the deal is generous.

Maintenance included

Maintenance is not a substitute for guaranteed backup availability. It keeps the lessor's equipment running, which makes you a secondary beneficiary rather than the party the duty runs to. It becomes a real benefit only where the lease converts it into an enforceable service obligation: a defined response time, a defined standard, and a consequence if the standard is missed.

Replacement included

"Replacement included" is only as good as the lease clause behind it. Is there a deadline — a number of days, not a promise of promptness? Is equivalent capacity required? Do your obligations pause while the battery is out of service? Are you compensated during extended downtime? A replacement promise with no deadline, no capacity floor, and no compensation is a statement of intent.

App access

Monitoring access, settings access, dispatch override, and final operating authority are four different rights, and the lease decides which of them you get. Seeing the battery's status is not controlling it — an app showing a state-of-charge percentage is a window, not a steering wheel. Ask which of the four you receive, and whether any can be revoked or overridden.

Grid participation

Grid participation counts as compensation to you only when you receive an enforceable payment, credit, or service in return. Enrollment is a use of the equipment, not a benefit conferred on you. If the lease promises a defined payment or credit per event, count it. If it is silent, the honest entry on your side of the ledger is zero.

How does a provider make money from a free home battery?

By owning a revenue-producing asset and parking it at your house. The provider is the lessor, you are the host, and the lease agreement is the instrument that routes every dollar the battery earns — which is why the lease, not the hardware and not the sales pitch, is the only document that tells you what you are getting.

One leased battery can produce value from several directions at once: federal tax benefits, state or utility incentives, virtual-power-plant and demand-response payments, capacity or grid-service revenue, electricity-price arbitrage, retail electricity revenue, customer-acquisition value, long-term operating rights, and programs that do not exist yet. Not every provider receives every category, and no honest article can tell you which ones a given company collects. Your side is limited to whatever backup, rate protection, credits, or payments the lease guarantees.

One item on that list is a clause you can read today. A lease may assign to the lessor the incentives, rebates, credits, and grid-program payments the system earns — including payments from programs that do not exist on the day you sign. The assignment is signed now; the money arrives later. Find the clause and read where it sends the money. (The New Jersey section below is where this bites hardest, and where the question to put in writing is spelled out.)

A brief note on federal tax, because it is the part most often misread. The Residential Clean Energy Credit (Section 25D) was terminated by the One Big Beautiful Bill Act (2025); the IRS says it "is not available for any property placed in service after December 31, 2025." But Section 25D only ever applied to equipment the homeowner owns. A leased, PPA, or provider-owned battery was never eligible for it, before or after the repeal — under a lease you were never in the tax picture at all, so nothing was taken from you.

The commercial side is unchanged: Section 48E was not repealed, and a business that owns qualifying storage may be eligible for it, though eligibility is not automatic. Federal law attaches those benefits to whoever owns the equipment, and under a lease the owner is the company. None of this is tax advice; ask a tax professional about your situation.

Why the stack matters to you

The issue is not that the provider earns money. A sustainable program must have an economic model. The concern arises when the provider receives definite ownership and operating rights while the customer's principal benefit remains uncertain. Most of what sits on the lessor's side of a lease tends to be definite — title, dispatch rights, an assignment clause, a grid-program contract. If your side is a set of expectations, the two columns are not comparable, and pretending they are is how a household ends up valuing an offer at the retail price of hardware it will never own.

Who controls the battery before an outage begins?

Whoever holds dispatch rights under the lease — usually the lessor, not you. Both interests are legitimate: the lessor has a reason to use stored energy, because that is how a battery earns grid revenue, and you have a reason to keep it for an outage nobody can schedule. The lease decides which one wins on any given evening.

How a backup reserve actually works

Most home battery systems have a "backup reserve" — a percentage of stored energy held back for outages. Energy above the reserve is what the system may discharge for bill savings or a grid event; during a real outage it can draw below the reserve, which is exactly what you want.

Most major systems also offer a severe-weather feature that charges toward full and pauses savings discharge when a National Weather Service watch or warning is issued for your area, pulling grid power when solar alone is not enough. On at least one major system, that feature cannot be switched on unless grid charging is enabled — and whether the setting is even visible in your app can be decided by the installer. The settings that determine your protection may be configured by someone other than you.

When a grid event discharges stored energy, an outage arriving before the battery recharges starts with less than a full tank, and how much less depends on the settings and dispatch rights in the lease. The counterweight is real: most reputable programs do include a customer-set reserve, a cap on events, a per-event opt-out, and pre-charging ahead of a forecast storm, and for many households the bad scenario never arrives. The point is narrower — those protections are lease features, not legal guarantees. New Jersey has not written the rules: as of July 2026 there is no finalized statewide virtual power plant (VPP) rulebook, the Board's April 2026 Request for Information closed to comments on May 20, 2026, and no order has issued. Until they land, your protection is whatever your lease says it is.

Nine questions to ask before you sign

1. Who sets the backup reserve — you, the lessor, or the installer at commissioning?
2. Can the lessor change the reserve after installation, and must it tell you?
3. Can you raise the reserve, and is that right in the lease or only in an app?
4. Can the lessor override your setting, and when?
5. Can you decline a dispatch event?
6. Are opt-outs limited in number, or penalized?
7. Can the battery be discharged shortly before an outage — during the evening peak on a stormy night, for example?
8. Does storm preparation take priority over grid-event activity when a watch or warning is issued?
9. What remedy do you have if the battery is depleted when the grid fails — compensation, restoration priority, termination rights, or nothing?

Question nine separates a marketing promise from a contractual obligation. If the answer is "that would not happen," ask for the sentence in the lease that makes it not happen.

Who pays for the electricity used to charge the battery?

Your meter sees it first. A home battery sits behind your utility meter, so grid electricity used to charge it registers as your household consumption — and whether you are billed, credited, or fully reimbursed for that energy, and for round-trip losses, is a lease question. Some programs credit the customer completely and automatically; others may handle it differently. The only way to know which you are being offered is to find the clause.

A lessor may earn revenue from dispatching a battery while the electricity used to prepare for that dispatch passes through your meter. The severe-weather pre-charge makes the same point from a friendlier angle: it may pull from the grid when solar alone is not enough — exactly what you want on a storm night — and that energy still crosses your meter. A battery also never returns everything put into it. Those losses belong to somebody, and the lease should say who.

1. Supply charges. The generation portion of the charging energy.
2. Utility delivery charges. The distribution portion, which a credit calculated on supply alone would not cover.
3. Taxes and surcharges. The line items that ride along with both.
4. Time-of-use pricing. If your rate varies by hour, charging at an expensive hour costs more — and the party choosing the hour may not be you.
5. Demand charges, where applicable. Worth confirming rather than assuming.
6. Round-trip efficiency losses. The energy that goes in and does not come back out.
7. Whether reimbursements are automatic and complete. Automatic means you need not notice, calculate, and claim. Complete means the credit covers delivery and taxes, not just supply.

Items six and seven are where good programs separate themselves: a lessor that credits you automatically, at the full delivered cost, and shows the math on your statement has answered the question before you had to ask it.

Can a free-battery program require you to switch electricity suppliers in New Jersey?

Yes. New Jersey is a retail-choice state, so a battery program can be bundled with a requirement that you buy your supply from a licensed third-party supplier — a second long-term agreement, separate from the battery lease, with its own terms and its own exit.

What the supply contract does and does not change

Supply is separate from delivery: you may buy generation supply from a BPU-licensed third-party supplier while your utility still delivers the power, and if you choose no supplier you get Basic Generation Service by default. That separation is why a battery offer can be bundled with a supply contract at all.

Switching supply does not change who keeps your lights on. NJBPU says your utility "will continue to deliver electricity... through the utility's wires and pipes" and "will also respond to emergencies, should they arise, regardless of where those supplies are purchased." In New Jersey that is PSE&G, JCP&L, Atlantic City Electric, or Rockland Electric. It is never the battery lessor. The Board licenses suppliers and enforces disclosure and marketing rules, but it does not set or cap their prices: a licensed supplier is one the state vetted for disclosure, not certified as cheap.

The benchmark moves

Your utility's "Price to Compare" is the portion of the bill a supplier's charges would replace. It is a benchmark for supply only — not delivery — and it moves: NJBPU says it "will generally change seasonally on June 1st and October 1st," and it can change at other times too. The Board puts the payoff conditionally: a customer who finds a price below the Price to Compare "may be able to save money," with "may" set in italics on its own page.

The shape of the rate matters as much as the number. NJBPU says supplier contracts are "based upon a FIXED price per unit, a VARIABLE price per unit, or a combination where the price is fixed for a set period of time and then changes to a variable price," and tells consumers to "ask the supplier if the rate can become variable during the contract term" and whether a variable rate has "a cap, or maximum price... or is there no limit to how high the price can go." The Board does not require a cap. It tells you to find out whether one exists.

If the offer is bundled with a switch to a licensed supplier, New Jersey rules give you a rescission window: your utility must confirm the switch in writing, and you have at least seven calendar days from that confirmation to contact the utility and rescind. Read the limit carefully, because it is the lease point in miniature. That right covers the third-party supply contract only. It does not cover a battery lease, a power purchase agreement, or a grid-services enrollment — those are separate contracts with their own cancellation terms, so find the cancellation clause in the lease and read it before you sign.

The same limit runs through every supplier protection above: these Board rules reach licensed energy suppliers. If the battery comes under a lease, PPA, or VPP enrollment rather than a supply contract, those rights do not apply — ask, in writing, which one you are signing. NJBPU's Division of Customer Assistance handles complaints about utilities and licensed suppliers; complaints about a battery lease or PPA provider generally belong with the New Jersey Division of Consumer Affairs, which enforces the Consumer Fraud Act. To vet the company, ask for its New Jersey Home Improvement Contractor (HIC) registration and electrical contractor credentials, both verifiable through that division.

What to check in both agreements

1. Is enrollment with a designated supplier mandatory, or optional?
2. Does switching suppliers later — or returning to Basic Generation Service — end the battery program or trigger a charge?
3. Is the supply rate fixed, variable, or fixed for a period and then variable?
4. What happens when the introductory period expires — what rate applies, and who tells you it changed?
5. Which utility rate is the comparison benchmark, and is it the current Price to Compare?
6. May the supplier change the comparison methodology during the term?
7. Does cancelling the supply agreement trigger battery removal, restoration costs, or fees under the lease?
8. Do the supply obligations run as long as the lease — and can missing a payment under one terminate the other? Ask that directly and get the answer in writing.

Does a savings guarantee mean your bill will always be right?

Not necessarily. A savings guarantee may not prevent a single unfavorable charge — depending on its terms, it may only give you a way to get money back after you discover the difference, document it, and file a timely claim.

"Guarantee" sounds like a control on the bill. It may be a refund mechanism instead, and a refund mechanism pays out only when somebody triggers it. Notice where it lives, too: if it sits inside the lease rather than a licensed supplier's contract, New Jersey's supplier rules do not reach it, and the lease is holding it up alone.

Reactive versus preventive

A preventive guarantee changes the charge before it lands on your bill. A reactive one changes it afterward, and only if a claim is made. If you have to find the discrepancy and file it yourself, consequences follow from the structure:

• The provider may not review every account every month.
• The monitoring burden sits with you.
• The comparison may be hard to reproduce — the benchmark, the methodology, and the billing data are not in your hands.
• You may never notice, or notice late and miss the claim window.
• Where the only remedy is returning the disputed difference, there may be no interest and no penalty.

A promise to return an unfavorable difference after you detect and prove it is not equivalent to a promise that every bill will automatically reflect the best applicable price. If the only consequence is returning money that should not have been charged under the guarantee, the mechanism may provide little preventive or deterrent value.

The existence of a claim process does not prove that a supplier intends to overcharge. The legitimate structural concern is that a claim-dependent guarantee may place detection and enforcement responsibility on the customer. And in New Jersey the benchmark moves underneath you: the utility's Price to Compare resets seasonally, and NJBPU frames the outcome conditionally — a customer who beats it "may be able to save money." A moving benchmark makes a moving promise.

Twelve questions a savings guarantee must answer

A guarantee that cannot answer these in writing is not a guarantee you can price.

1. Is the rate comparison performed automatically, every billing period?
2. Is any resulting credit applied automatically, or must it be requested?
3. Must you submit a claim to get the benefit of the guarantee?
4. Who calculates the benchmark it is measured against?
5. Can you verify that benchmark independently, from published information?
6. Are delivery charges, taxes, and fees included, or only the supply portion?
7. Is the guarantee based on the rate per unit, or on total cost?
8. How long is the claim window, and when does it start running?
9. Does a refund include interest, or only the bare difference?
10. What happens after repeated discrepancies — any escalating remedy, or none?
11. Can the methodology change during the term, and on what notice?
12. Does the guarantee run for the entire agreement, or only an introductory period?

Why should trust not be the homeowner's main protection?

Because the lessor holds every switch and every record — the billing data, the battery's operation, the reserve setting, the program accounting — and you hold a copy of the lease.

Trust is not a mechanism. It cannot be audited, it cannot be enforced, and it does not survive the day your lease is assigned to a company you have never spoken to. The clause survives. So ask for these nine items in the lease, and expect a well-run program to welcome every one — none of it costs an honest lessor anything.

1. Automatic rate comparisons every billing period, without a customer request.
2. Automatic credits, applied to the bill rather than paid on a successful claim.
3. Visible dispatch records showing when the battery was discharged, and why.
4. Access to state-of-charge history, so you can see what was in the battery before and after each event.
5. Transparent grid-program accounting — what the system earned, and what portion, if any, comes back to you.
6. Reserve obligations stated as a measurable minimum, not as an intention.
7. An independent dispute procedure that does not rest solely on the lessor's own review.
8. Meaningful remedies for repeated failure, not just a correction of the last one.
9. Termination rights when the core promises of the lease are not met.

Key takeaway: Trust should follow transparent performance and enforceable obligations. It should not substitute for them.

Are the homeowner's obligations more definite than the homeowner's benefits?

In many leases, yes. What you owe is fixed the day you sign; what you get may be contingent on outcomes nobody has promised you.

Definite from the day you sign:

• A long lease term.
• The lessor's ownership of the equipment bolted to your house.
• The lessor's operating rights, including authority to charge and discharge the battery.
• Any required enrollment with a designated electricity supplier.
• Your transfer duties if you sell, and consent requirements for changes to your own electrical system.
• Site access for the lessor, and cancellation or removal terms with costs attached.

Contingent, unless the lease says otherwise:

• Backup power, if enough energy happens to be stored when the outage begins.
• Savings, if the benchmark moves your way and the guarantee is honored on its terms.
• Bill credits, if any are promised in writing rather than described as typical.
• Any share of grid-program or virtual power plant (VPP) revenue, which you get only if the lease promises it.
• Any ownership interest in the equipment, which you have only if the lease grants it.

Be cautious about accepting definite, long-term obligations in exchange for a benefit the lessor expressly declines to guarantee. If that describes the lease in front of you, ask for the benefits to be written down as precisely as the obligations already are.

Could a provider-owned battery affect who claims New Jersey's coming storage incentives?

It might — and the clause that decides it is sitting in the lease right now. As of July 14, 2026 nobody, the state included, can tell you for certain, because New Jersey has no open rebate or performance-incentive program that pays homeowners for a home battery, and the rules that will decide who gets paid under the Garden State Energy Storage Program's distributed segment are still being written.

So start with the lease, not the state. The lease is signed today; the incentive may arrive years from now. A lease may assign to the lessor every incentive, rebate, tax credit, and grid-program payment the battery earns — including payments from programs that do not exist on the day you sign. That clause waits for nothing and depends on no state program existing. It is in the document already in your hands. Find it, read it, and get one question answered in writing: if New Jersey opens a residential storage incentive on this battery, who receives it — me or you?

Where New Jersey's storage program actually stands today

The timing is what makes that clause bite. Read the no-open-program fact precisely, though: it does not mean the state does nothing for home batteries. Two long-standing New Jersey tax breaks do apply — a sales-tax exemption for devices that store solar-generated energy, and a renewable-energy property-tax exemption. Neither is a cash rebate, and neither answers the ownership question.

The Garden State Energy Storage Program (GSESP) has exactly one solicitation open — Phase 1, Tranche 2, opened May 20, 2026 — and it is limited to transmission-scale systems of at least 5 MW AC, hundreds of times larger than a home battery. Homeowners cannot participate. Home batteries would live in the distributed segment, and GSESP Phase 2 has not launched: the Board's June 18, 2025 order said it was "not finalizing the design of Phase 2 in this Order," and as of July 14, 2026 no Phase 2 order has issued and no applications are open.

Residential eligibility inside Phase 2 is anticipated but not settled. In that order, BPU Staff declined to create a dedicated residential segment, stating that "smaller, residential-size projects is not the most direct pathway to achieve the legislatively mandated goal ... at this stage of program development." No incentive amounts are set either — Phase 2 levels "will be set to reflect market conditions at the time those phases of the program are released." Any per-kWh or per-kW figure quoted to you today is an installer's estimate, not an approved state rate.

Momentum is real. Governor Sherrill's Executive Order No. 2, signed January 20, 2026, proclaimed a state of emergency over electricity affordability and directed the Board of Public Utilities to launch GSESP Phase 2 and, within 180 days, to "commence the development of a 'virtual power plant' program in the State." But these are directives to begin work, not live programs. As of July 2026 New Jersey has no operating VPP program: the Board is still at the Request for Information stage, with no rules, no enrollment process, and no payment levels adopted.

Why ownership is the question the state itself is asking

The NJBPU's proposed GSESP rules (N.J.A.C. 14:8-14, published August 2025 and not yet adopted) make distributed projects eligible when they are "owned, leased, or operated by a residential or non-residential customer" of an electric utility — so leased systems are expressly contemplated. The proposed rules do not shut a leased battery out. They also do not say the host, rather than the equipment owner, collects. Who gets the money on a leased battery is not answered yet, by anyone.

In a Request for Information issued April 20, 2026 (revised May 6, 2026; responses due May 20, 2026), NJBPU Staff asked stakeholders how the Board should prevent a storage system from being "compensated for the same service more than once" if it joins both GSESP Phase 2 and a future, state-administered VPP program. Note what that is not. It is not a decided rule — Staff asked a question; the Board has adopted nothing. It is not about a private, provider-run grid program. And it costs nobody anything today, because no one is receiving Phase 2 incentives yet.

In the same RFI, Staff asked the state's four electric utilities to describe who owns an incentivized asset and how long the utility retains dispatch rights over it — an information-gathering question put to utilities about their own programs, not a rule and not a finding about any company. But it tells you which two terms regulators treat as defining: who owns the hardware, and who controls when it discharges. Federal framing runs the same way. The U.S. Department of Energy says virtual power plants "enroll DER owners... in a variety of participation models that offer financial rewards." Note DOE's word: owners. Under a lease, the owner is the lessor — which is precisely why the lease, and not anyone's goodwill, decides where that money goes.

None of that establishes what any particular provider will do. A leased battery program can be entirely legal and legitimate, and fully disclosed in the document you are handed. The point is narrower: when the regulator is still asking who owns the asset and who holds dispatch rights, those are the two questions to settle in the lease before you sign it.

Six questions to get answered in writing before you sign

Do not accept verbal answers. Every one of these is a clause, and it belongs in the lease or in a signed addendum to it.

1. Does this lease assign to you any state incentive, rebate, tax credit, or grid revenue my battery earns?
2. If New Jersey opens a residential storage incentive on this battery, who receives it — me or you?
3. Does that assignment reach programs that do not exist yet, or only programs open today?
4. Who legally owns the battery, and for how long?
5. Am I barred from applying for a New Jersey incentive myself — and if I later want to claim one, can I exit this lease, and at what cost?
6. Who holds dispatch rights, and can you discharge my battery when I want it saved for backup?

Nobody — including the state — can tell you today whether a lease signed now will cost you a future New Jersey incentive, because the rules that decide who gets paid are still being written. That is a reason to get the answer in writing before you sign. It is not a reason to assume the worst.

What happens when you sell your home or want out of a free-battery agreement?

The lease decides, and it usually decides against convenience. It may require your buyer to assume it, let the lessor approve or reject that buyer, impose transfer or early-termination fees, or make you pay off or remove the equipment before closing.

Selling the home

A leased battery does not simply convey with the house. Somebody else's equipment is bolted to your wall, and a lessor with approval rights over your buyer is a third party inside your closing. If the buyer will not assume the lease, the alternatives are usually a payoff, a removal, an early-termination charge, or some combination — each with a cost, at the least convenient moment in a New Jersey closing.

Read the other direction too, because many leases let the lessor assign the agreement onward. The company you sign with today may not be the company holding your lease years into the term, so find out what survives that transfer: servicing obligations, software and app access, and what operating rights the new holder acquires over the battery on your house.

Living with the lease

The lease governs the years in between, and it can constrain ordinary decisions about your own house: a new roof, adding solar, adding a generator or a second battery, upgrading electrical service, keeping the internet connection the lessor needs to dispatch the equipment, letting the lessor onto your property. Some require consent. Some create costs you pay. All stay fully in force even if backup availability never materializes. They are definite. The backup, unless the lease expressly guarantees it, is not. Fourteen clauses to find and read before you sign:

1. Buyer assumption — must the purchaser of your home take over the lease?
2. Lessor approval — can the lessor reject that buyer, and on what criteria?
3. Payoff or removal options — what are they, and what do they cost?
4. Transfer fees charged when the lease moves to a new owner.
5. Early-termination charges, and how they are calculated.
6. What happens if the buyer simply refuses to assume the lease.
7. The lessor's right to assign the lease to another company.
8. End of term — does ownership transfer to you, is the equipment removed, or does the term renew?
9. Roof replacement — who removes and reinstalls the equipment, and who pays?
10. Adding solar later — is the lessor's consent required?
11. Adding a generator or a second battery — is it permitted at all?
12. Electrical-service changes and panel upgrades — what consent is required?
13. Maintaining internet access, and what happens if connectivity lapses.
14. Lessor entry onto the property — with what notice, and for what purposes?

How should you value a free home battery offer before you sign?

Value only what the lease requires the lessor to deliver to you — not the retail price of the battery on your wall. The hardware has a price; the price is not your benefit. Your benefit is what the lessor must do, in writing, with a remedy if it does not. Six steps:

1. Assign zero guaranteed value to backup power the lease does not obligate the lessor to make available.
2. Assign zero value to incentives, rebates, or grid revenue the lease does not promise you — then check whether it assigns them away from you.
3. Treat maintenance of the lessor's own equipment as the owner's operating obligation, not as something resembling ownership.
4. Count savings only by the written benchmark and the written remedy — not an illustration, not an average.
5. Subtract what you give up: supplier restrictions, operating control, transfer obligations, consent requirements, cancellation limits.
6. Compare what is left against buying or financing a battery you own outright, where the reserve, the settings, any grid enrollment, and any incentive you may later qualify for all stay on your side of the table.

Then read the result honestly, in both directions. A no-upfront-cost battery is not necessarily a bad product. But if the homeowner receives no ownership, no program revenue, no enforceable rate savings, and no guaranteed backup reserve, the customer may be undertaking substantial long-term obligations while receiving very little guaranteed value in return.

If the offer survives those six steps, it may well fit your household. If it does not, ask for the missing pieces to be written into the lease. A lessor who will put a measurable reserve, an automatic credit, and a clear answer on incentives into the document has turned a contingent offer into a priceable one. A lessor who will not has left it where it started.

Key takeaway: A free battery is worth exactly what the lease requires it to be worth — no more, and no less.

Frequently Asked Questions About Free Home Battery Offers in New Jersey

Is a "free" home battery actually free once you read the agreement?

It may carry no upfront charge while you may be granting operating rights, property access, and - if the lease so provides - any claim to incentives or grid revenue the system earns. Read the lease for what you give, not just for what you are billed.

Do I own a home battery that a provider installs at no upfront cost?

Not unless the lease transfers title to you; bolting equipment to your wall does not make it yours. Ask whether ownership ever transfers, and if so, when, on what conditions, and at what cost.

Is backup power guaranteed under a free home-battery program?

Only if your lease promises a measurable minimum of stored energy and a remedy when it is not there. Capability language describes what the system can energize, not what is sitting in the battery when the outage starts.

Is a free battery worth it if backup power is not guaranteed in writing?

If backup is your reason for signing and the lease guarantees nothing else, the value you can actually enforce may be very small. Assign zero guaranteed value to anything the lessor is not obligated to deliver.

What is the difference between a backup reserve target and a backup guarantee?

A target is an operating objective that whoever controls the settings can change. A guarantee states a minimum, when it is measured, and what you get if the energy is not there.

Can a virtual power plant discharge my battery before an outage begins?

It may, if the lease permits it. Get the minimum reserve, the cap on events, the per-event opt-out, and storm pre-charging written into the lease - they are contract features, not legal guarantees.

What happens if a VPP event leaves my battery nearly empty when the power fails?

A grid event lowers the state of charge, so an outage that arrives before the battery recharges starts with less energy. Check whether your lease attaches any consequence at all to an empty battery.

Does "whole-home backup" in a provider agreement guarantee my home stays powered all night?

No. It describes which loads the system is wired to energize, not how much energy is stored when the outage begins - and only stored energy determines runtime.

Can I raise my battery's backup reserve before a storm if the provider controls the settings?

Only if the lease gives you an enforceable settings or override right. App access may let you watch the reserve without changing it, so ask who holds final operating authority.

Can the provider override my battery settings after installation?

It may, if the lease gives it that authority. Monitoring access, settings access, dispatch override, and final operating authority are four different rights - find out which of them are yours.

Can I opt out of VPP dispatch events under a free-battery contract?

Only if the lease says so, on the terms it sets. Ask whether opt-outs are capped, whether they carry fees or termination, and whether one is available ahead of a forecast storm.

Who receives the VPP payments earned by a battery installed at my home?

Your lease controls. The U.S. Department of Energy describes virtual power plants as enrolling the owners of these resources in models that offer financial rewards - so ask, in writing, what your lease pays you.

Who keeps the battery incentives and tax benefits when a third party owns the equipment?

Incentives and tax benefits follow ownership or a contractual assignment, and a lease may assign to the lessor every incentive, rebate, credit, and grid payment the system earns - including from programs that do not exist on the day you sign. Find the assignment clause in your lease and get a written answer to one question: if New Jersey opens a residential storage incentive on this battery, who receives it, me or you?

Does the homeowner receive any of the battery-arbitrage profits?

Only if your lease provides revenue sharing, credits, or other defined compensation. If it is silent, assume the answer is no and price it at zero.

Who pays for the electricity used to charge a provider-owned battery?

A home battery sits behind your meter, so grid charging registers as your household consumption. Whether you are billed, credited, or reimbursed for that energy and its round-trip losses is a lease question - some programs do credit the customer, so ask.

Does a savings guarantee mean I will always save money on my electric bill?

Not necessarily. It may apply only to a defined benchmark and to part of your bill, and NJBPU says only that a customer who beats the utility's Price to Compare "may be able to save money."

Does a refund-style savings guarantee prevent an unfavorable charge in the first place?

Not necessarily. Depending on its terms it may only correct a qualifying difference after it has been billed, which can leave detection and enforcement sitting on your side of the table.

Do I have to discover and report a billing shortfall myself to collect on the guarantee?

That depends on the terms, and it is the first thing to check. A promise to return a difference after you find it and prove it is not a promise that every bill will be right.

Does a battery savings guarantee cover my entire electric bill or only part of it?

It may cover only the supply portion or one comparison rate - not delivery charges, taxes, or fees. Ask who calculates the benchmark and whether you can reproduce it, because a guarantee you cannot verify is one you cannot enforce.

Can a battery program require me to switch electricity suppliers?

Some programs may require a designated supplier, which New Jersey's retail-choice market makes possible, so read the supply contract and the battery lease as two separate long-term commitments. Switching supply never changes who restores your power.

How does a provider make money from giving me a free battery?

Possible sources include federal tax benefits, state or utility incentives, grid-program payments, electricity-market value, retail energy revenue, customer-acquisition value, and long-term operating rights. Earning money is not the problem - ask in writing what the lease sends back to you.

Is "included maintenance" a real homeowner benefit when the provider owns the battery?

It is worth something to you only where the lease turns it into an enforceable service obligation; otherwise it keeps the lessor's revenue-producing asset running. Ask for a repair deadline, equivalent replacement capacity, and compensation while you are without the battery.

What happens to a provider-owned battery agreement when I sell my home?

Whatever the lease says. It may require your buyer to assume it, require the lessor's approval of that buyer, impose a transfer fee, or require payoff or removal before you can close.

Does a free-battery contract restrict adding solar, a generator, or a second battery later?

It may. A lease can require the lessor's consent for electrical modifications and additional energy equipment, and that clause often reaches roof replacement and changes to your electrical service.

What happens to my battery contract and equipment if the provider goes out of business or is acquired?

Read the assignment, servicing, software-access, warranty, operating-control, and removal provisions before you sign. A lease can be sold, and the company you sign with today may not be the company holding your lease years into the term.

Is buying a battery outright better than accepting a provider-owned free battery?

Owning it puts the reserve, the settings, and any grid-program enrollment in your hands, but you have to buy or finance the equipment. On taxes: the federal Residential Clean Energy Credit (Section 25D) is no longer available for homeowner-owned property placed in service after December 31, 2025, and it never applied to a leased or provider-owned battery in the first place - so no lease ever put you in the tax picture.

What should a genuine written backup guarantee include in a battery contract?

A measurable minimum reserve, a defined time and method of measurement, limits on discharging below it, override and opt-out rights, restoration duties after a dispatch, and access to your own performance records. And a remedy with teeth when the reserve is repeatedly not there.

When should I assign zero value to the backup a free-battery offer promises?

Whenever the lease does not require a measurable amount of usable energy to be available when an outage begins. Only an obligation has guaranteed value.

Your Next Step for a Home Battery You Actually Own in New Jersey

Owning the battery keeps ownership, control, and the backup reserve on your side of the table. When the equipment is yours, you decide how much energy stays in reserve for an outage, nobody else holds dispatch rights over it, and you are the party who would apply for any grid-program revenue or any future New Jersey incentive the system may qualify for. New Jersey has not yet decided who may claim a residential storage incentive on a system a third party owns - which is exactly why the answer should be in writing before you sign anything.

Powerlutions designs and installs owner-operated battery systems for New Jersey homes. You set the reserve. You decide whether to enroll in a grid program. You apply for whatever it pays.
