Updated November 2026. Home battery incentives in New Jersey changed a lot this year, and plenty of pages online (including an earlier version of this one) still quote numbers that no longer apply. Here's the straight version of what a homeowner can actually get today.
The Short Answer
- Open now (PSE&G customers): PSE&G's GridSmart Battery Program pays $5,000 toward a qualifying home battery, plus up to $25,000 of the remaining cost as interest-free on-bill repayment. It's a pilot that launched August 26, 2026.
- Proposed, not open: the statewide Garden State Energy Storage Program (GSESP) home-battery block. NJBPU released a straw proposal in August 2026; rates aren't final and you can't enroll yet.
- Gone: the federal 30% Residential Clean Energy Credit (Section 25D) for homeowner-owned batteries ended for systems installed after December 31, 2025.
PSE&G GridSmart Battery Program
According to PSE&G's announcement, GridSmart is part of the utility's residential virtual power plant pilot. In exchange for the $5,000 incentive, your enrolled battery may be called on during scheduled "GridSmart Battery Events" — planned peak-demand periods when the battery powers your home instead of the grid. You're notified in advance, and the battery still backs you up in an outage.
Program requirements and the list of qualifying battery systems are on pseg.com/GridSmart. We confirm eligibility for your specific system during the free assessment.
The Garden State Energy Storage Program (Proposal)
NJBPU's August 2026 straw proposal for GSESP Phase 2, Block 1 would add roughly 150 MW of storage statewide, including behind-the-meter home batteries. Enrolled homeowners would receive annual performance-based payments over a 10-year term for supporting the grid during dispatch events like heat waves and cold snaps, administered through the utilities (PSE&G, JCP&L, ACE and RECO). It's still a proposal: incentive rates haven't been set and enrollment isn't open. We'll update this page when it is.
What a Powerwall 3 Costs a PSE&G Customer Today
- Installed cost (equipment + installation): approximately $14,000
- PSE&G GridSmart incentive: −$5,000
- Net cost: approximately $9,000 — with the option to spread the rest interest-free on your PSE&G bill
On top of that, PSE&G's time-of-use rate rewards a battery every day: charge overnight at off-peak prices and run the house through the 4–9 PM weekday peak. Want numbers for your house? Get a home battery quote.
Which Batteries Do We Install?
We're a Tesla Certified Installer for the Powerwall 3 (13.5 kWh, built-in inverter), and we install other major residential systems as well. Whether a given model qualifies for GridSmart depends on PSE&G's approved-hardware list, which we check before you commit.
Do You Need Solar to Install a Home Battery?
No. This is one of the most common misconceptions about home battery storage. A standalone battery connected to your main electrical panel — without solar — works fine — and can still qualify for PSE&G's GridSmart incentive if it's an approved system. You charge the battery from the grid during off-peak hours and discharge it during peak hours, or you use it as backup power during outages.
That said, pairing a battery with solar does maximize the system's value. With solar, your battery charges from free solar production during the day and acts as backup at night and during grid outages. We install both solar-paired and standalone battery systems across NJ.
The Permit and Inspection Process in NJ
Battery storage installations in New Jersey require an electrical permit through your local municipality's construction office, a NJ electrical inspection, and in most cases a utility interconnection agreement with PSE&G or JCPL. The interconnection process can add 4–8 weeks to the project timeline, so plan accordingly if you have a deadline (like wanting backup power before hurricane season).
We manage the full permit and interconnection process for every battery installation we do. This includes preparing the interconnection application, coordinating the utility site visit, and scheduling the municipal electrical inspection.
When Should You Act?
Two factors make now a good time: PSE&G's GridSmart pilot is open (pilots have limited enrollment and can close), and PSE&G's time-of-use rate makes peak-hour battery discharge pay off every weekday — not just during outages.
We recommend homeowners who are seriously considering a battery installation get on our schedule now so the full permit and interconnection process can be completed before peak summer demand hits. Call (848) 294-1739 or visit malfettoneelectric.com/contact for a free site assessment.
