New Jersey's Home Battery Incentive Pays $200 per kW on Paper. The State's Own Example Pays $540 a Year.

If you’re in New Jersey and an installer just pitched you a battery on the promise of state incentive money, ask which number they’re quoting. The headline rate is $200 per kW a year. The state’s own worked example pays $540 a year.

And if you install before the program opens, you may not get any of it.

What New Jersey is proposing

The Board of Public Utilities wants 2,000 megawatts of energy storage by 2030. Part of that plan is Block 1 of the Garden State Energy Storage Program: 150 megawatts of home batteries, enrolled first come, first served through your utility. PSE&G gets 73 MW of that, JCP&L 52, Atlantic City Electric 21, and Rockland Electric 4.

The deal: your utility can call on your battery up to 35 times a year, for events of up to four hours, during heat waves and cold snaps. You get paid every year for 10 years based on how much your battery actually pushes out during those events.

Here’s the catch. The $200 is the ceiling. BPU staff calls it “the maximum annual payment available to a project achieving a 100% Performance Factor.” That factor measures the lowest output your battery holds during each event, averaged across the year and compared with its rated power.

The math the installer skips

The straw proposal does the math itself, which is refreshingly honest. Take a common 13.5 kWh battery rated at 11.5 kW. Multiply 11.5 kW by $200 and you get the brochure number: $2,300 a year.

But a 13.5 kWh battery can’t hold 11.5 kW for three and a half hours. It runs out. In the BPU’s example, it averages 2.7 kW across 35 events. That’s a 23.5% Performance Factor, and a payment of $540 a year.

Over the full 10-year term, that’s about $5,400, assuming the battery performs the same every year. Real money. Not a battery’s worth of money.

Our verdict: a fair program with a misleading headline rate. Buy a battery because you want backup power. Count the incentive as a bonus.

The timing trap

Block 1 is only for new batteries. The proposal says a system can’t have “previously achieved commercial operation prior to program application,” and existing systems are out “unless explicitly authorized through future program guidance.”

BPU staff expected to bring the program order to the Board this month. Utilities would file plans in December. Staff anticipates Block 1 opening by July 2027. So a battery you switch on next spring doesn’t qualify for Block 1 as written.

The state does keep a separate interim program for batteries and other equipment homeowners already own. It’s still being designed, so nobody can tell you what it pays yet.

What to do now

If you’re shopping for a battery anyway, check what your utility pays today. The current utility storage programs keep running until Block 1 opens, and then Block 1 becomes the only incentive for new home batteries. PSE&G’s GridSmart program, announced in August, offers $5,000 toward a qualifying battery plus up to $25,000 in interest-free on-bill financing.

If you’re not in a hurry, file this away for spring 2027 and watch for your utility’s Block 1 filing.

Either way, get the battery’s power rating and its usable kWh in writing. Divide kWh by four. That’s roughly the power it can hold through a full four-hour event, and a better guide to your payment than the rating on the box.
