New Jersey's Garden State Energy Storage Program is building toward residential battery incentives in Phase 2 (2026). This guide covers the program timeline, TOU rate savings with PSE&G/JCP&L/ACE, current battery options, and how to design a battery-ready solar system today.
Program: Garden State Energy Storage Program (GSESP)
Phase 1: Utility-scale/commercial — approved June 2025
Phase 2: Residential — expected 2026 (details TBD)
Battery cost: $10,000-$18,000 installed (no federal credit)
TOU savings: $350-$600/year (PSE&G RS-TOU-3P)
No federal credit: Section 25D expired Dec 31, 2025
Phase 2 incentive amounts not finalized. Install battery-ready solar now to position for Phase 2 when it launches.
New Jersey has set one of the most ambitious energy storage targets on the East Coast — 2,000 MW by 2030. The Garden State Energy Storage Program (GSESP) is the state's primary vehicle for meeting that goal.
Approved by the NJ BPU in June 2025. Targets grid-scale battery projects and commercial behind-the-meter installations.
Expected to launch during 2026. Will provide incentives for homeowners installing battery storage systems, potentially paired with solar.
Why this matters: Once Phase 2 launches, early adopters who installed battery-ready solar systems may be positioned to add batteries at lower net cost. Designing your solar system with battery compatibility (hybrid inverter, panel capacity, electrical panel upgrade) today avoids costly retrofits later.
Even without Phase 2 incentives, three factors are driving NJ homeowners toward battery storage: TOU rate optimization, storm resilience, and SREC-II value stacking.
PSE&G is launching its RS-TOU-3P time-of-use rate in June 2026. Batteries charge during low-cost off-peak hours and discharge during expensive peak hours, capturing the rate spread.
Estimated TOU Spread
$0.08-$0.12/kWh
Annual savings: $350-$600 with 13.5 kWh battery
NJ experienced 14 major outage events in 2024-2025. Nor'easters, hurricanes, and summer thunderstorms leave hundreds of thousands without power. A battery keeps critical loads running for 8-24 hours.
Backup Duration (13.5 kWh)
8-24 hours
Depends on loads: essentials vs whole-home
Adding a battery to a solar system does not affect your SREC-II eligibility. You still earn $76.50/MWh for 15 years on every MWh your solar panels generate. The battery adds TOU savings and backup value on top.
Combined Annual Value
$2,500-$3,400/yr
SREC-II + net metering + TOU (8 kW solar + battery)

Design My SystemYou do not need to wait for Phase 2 to install a battery. These are the top residential battery systems available in New Jersey today. All prices are installed cost, without any state or federal incentives (Section 25D expired Dec 31, 2025).
No federal credit for batteries in 2026. The Section 25D residential clean energy credit expired December 31, 2025. There is no federal tax credit available for residential battery purchases in 2026. Third-party-owned systems (PPA/lease) may still access the Section 48 commercial ITC through the financing company.
Without federal incentives, battery economics depend heavily on TOU rate arbitrage, backup value, and potential Phase 2 incentives. Here is a realistic breakdown using PSE&G TOU rates.
Rate Structure (Estimated)
Daily Battery Cycle
Annual TOU Savings Summary
Conservative (250 cycles/yr)
$365
Moderate (300 cycles/yr)
$438
Aggressive (340 cycles/yr)
$496
Bottom line: Solar + battery in NJ pays for itself in approximately 10-13 years at current rates, even without federal incentives. If Phase 2 provides $3,000-$5,000 in state battery incentives (speculative), payback could drop to 8-11 years. The backup value during storms is difficult to quantify but consistently cited by NJ homeowners as their primary motivation.
If you are installing solar in 2026, designing your system for future battery addition is straightforward and low-cost. Here is what to specify with your installer.
A hybrid (battery-ready) inverter costs only $500-$1,000 more than a standard string inverter. It eliminates the need to replace your inverter later when you add a battery. Enphase microinverter systems are inherently battery-compatible.
Many NJ homes have 100A or 150A panels. Battery systems typically require a 200A main panel. Upgrading during solar installation saves $1,000-$2,000 compared to doing it separately later. A Span smart panel is also an option.
Have your installer run empty conduit from your electrical panel to your intended battery location (garage, basement, or exterior wall). This takes 30 minutes during installation and avoids drywall work later.
Batteries need a climate-controlled location (garage or basement ideal) with adequate ventilation and clearance. Plan the location now so electrical runs are short and code-compliant.
Phase 2 may be retroactive. While not confirmed, several BPU stakeholder comments have suggested that Phase 2 incentives could apply to batteries installed before the program launch date. This is not guaranteed, but designing battery-ready now costs very little and positions you for either scenario.

Connecticut is the current leader in Northeast residential battery incentives. Here is how NJ compares — and what Phase 2 might change.
| Feature | New Jersey (2026) | Connecticut (Active) |
|---|---|---|
| State Battery Incentive | Phase 2 pending (TBD) | Up to $16,500 (ESS program) |
| Program Name | Garden State Energy Storage | Energy Storage Solutions (ESS) |
| Residential Status | Not yet active | Active and accepting applications |
| TOU Rate Spread | ~$0.12/kWh (PSE&G estimated) | ~$0.08/kWh (Eversource) |
| Solar Production Incentive | SREC-II: $76.50/MWh (15 yr) | LREC: ~$25/MWh (15 yr) |
| Avg Electric Rate | $0.26/kWh | $0.27/kWh |
| Federal Credit (25D) | Expired ($0) | Expired ($0) |
NJ advantage: NJ's SREC-II program pays 3x more than CT's LREC for solar production. Even without battery incentives, NJ homeowners earn significantly more from solar. When Phase 2 launches, the combined solar + battery value in NJ could surpass CT. NJ also has a larger TOU rate spread with PSE&G's new TOU program.

Tranche 1 Results: Three projects totaling 355 MW were awarded — Woods Landing Storage (200 MW), Two Rivers Energy Storage (150 MW), and North America Energy Storage Corp. (5 MW). Projects must achieve commercial operation within 36 months.
Tranche 2 Launched: A second solicitation for 645 MW of additional storage opened March 4, 2026. Pre-qualification due June 10, 2026; final bids due August 7, 2026; Board decision by October 28, 2026.
Phase 2 (Residential): Behind-the-meter incentives for homeowners and businesses are expected later in 2026. Details TBD — expected to include both an upfront incentive and performance-based payments for grid dispatch participation. This will be NJ's first dedicated residential battery incentive program.
The Garden State Energy Storage Program (GSESP) is New Jersey's state-level initiative to increase battery storage deployment. Phase 1 (approved June 2025) focuses on utility-scale and commercial storage with a 2,000 MW target by 2030. Phase 2, expected in 2026, will extend incentives to residential battery systems. The program is administered by the NJ BPU (Board of Public Utilities).
Phase 2 of the Garden State Energy Storage Program, which covers residential batteries, is expected to be finalized and launched during 2026. The NJ BPU opened a stakeholder process in late 2025. Specific incentive amounts, eligibility requirements, and application procedures have not been published yet. Monitor NJ BPU announcements for updates.
A home battery system in NJ costs $10,000 to $18,000 installed depending on the model and capacity. The Tesla Powerwall 3 (13.5 kWh) runs $12,000-$15,000 installed. Enphase IQ 5P (5 kWh) starts at $6,000-$8,000 per unit. Franklin aPower2 (13.6 kWh) runs $12,000-$16,000. These prices do not include any potential Phase 2 incentives. The federal Section 25D residential tax credit expired Dec 31, 2025 — there is no federal credit for residential batteries in 2026.
Yes. PSE&G is launching its RS-TOU-3P time-of-use rate in June 2026 with an estimated $0.08-$0.12/kWh spread between off-peak and on-peak prices. A battery can charge from solar during off-peak hours and discharge during peak hours. With a 13.5 kWh battery cycling daily, this could save $350-$600/year on TOU rate optimization alone — before backup value.
No. You can install a standalone battery system without solar panels. However, the economics are significantly better with solar — the battery stores excess solar generation that would otherwise be exported at net metering rates. Solar + battery also qualifies for SREC-II payments on the solar portion. Most NJ homeowners install batteries paired with solar for maximum value.
Connecticut is currently ahead of NJ for residential battery incentives. CT's Energy Storage Solutions (ESS) program offers up to $16,500 in upfront incentives for residential batteries paired with solar. NJ's Phase 2 residential incentives have not been finalized yet. However, NJ's TOU rate spreads, SREC-II value stacking, and higher storm risk may make batteries equally attractive once Phase 2 launches.
