New Jersey is one of the most active solar markets in the Northeast, driven by strong state incentives, four major electric distribution companies serving the state, and a mature installer and EPC ecosystem. If you are designing solar plan sets for New Jersey projects — whether residential, commercial, or community solar — this guide walks through the permit landscape, the four utilities, the top AHJs, and the common patterns that determine whether your plan set gets approved on first submission or comes back for revisions.
New Jersey solar at a glance
New Jersey ranks among the top 10 US states for cumulative solar installations. The state has a well-established solar incentive structure administered by the New Jersey Board of Public Utilities (NJBPU), a mature interconnection process across four major utilities, and an active commercial and community solar segment alongside strong residential volume.
Key jurisdictional facts for New Jersey solar design:
- State regulator: New Jersey Board of Public Utilities (NJBPU)
- Building code: New Jersey Uniform Construction Code (UCC), adopting the IBC/IRC with NJ amendments
- Electrical code: NEC as adopted by NJ (always verify the currently enforced edition with the AHJ)
- Solar incentive program: the Successor Solar Incentive (SuSI) program, which includes the Administratively Determined Incentive (ADI) and Competitive Solar Incentive (CSI)
- Four major EDCs covering essentially the entire state
The four major New Jersey electric distribution companies (EDCs)
Every solar project in New Jersey interconnects through one of four utilities. Which one depends on the street address of the project. Knowing the EDC upfront is essential because each has its own interconnection application, its own timeline, its own technical requirements, and its own approved equipment expectations.
1. PSE&G (Public Service Electric and Gas)
Public Service Electric and Gas is New Jersey's largest utility, serving approximately 2.3 million electric customers across northern and central NJ, including much of the metro area around Newark, Elizabeth, Jersey City, Trenton, and the Camden region on the Delaware River side. If your project is anywhere in the densely populated Northern NJ corridor, PSE&G is the most likely EDC.
PSE&G interconnection generally has one of the more efficient timelines among NJ utilities for standard residential and small commercial projects. Larger commercial and community solar projects follow a more structured queue-based process.
2. JCP&L (Jersey Central Power & Light)
Jersey Central Power & Light is a FirstEnergy subsidiary serving approximately 1.1 million customers across central and northern NJ, including much of the Jersey Shore, portions of Middlesex, Monmouth, Ocean, and other central NJ counties. Coastal areas from Sandy Hook down through Long Branch, Toms River, and into southern Ocean County are largely JCP&L territory.
JCP&L interconnection follows FirstEnergy's standardized process across their multi-state footprint, with New Jersey-specific application forms and approval workflows.
3. Atlantic City Electric (ACE)
Atlantic City Electric is an Exelon subsidiary (part of the Pepco Holdings group) serving approximately 560,000 customers across southern New Jersey, including Atlantic, Cape May, Cumberland, Salem, and portions of surrounding counties. If your project is in the southern NJ shore region or the rural southern counties, ACE is likely the EDC.
4. Rockland Electric Company (RECO)
Rockland Electric is a small subsidiary of Con Edison's Orange & Rockland Utilities, serving approximately 72,000 customers in a small territory in northern NJ (parts of Bergen and Passaic counties). RECO is the smallest of the four NJ EDCs but critical to know if your project falls within their footprint.
New Jersey Successor Solar Incentive (SuSI) program
New Jersey's current solar incentive framework is the Successor Solar Incentive program, established after the closure of the previous Solar Renewable Energy Certificate (SREC) market. SuSI provides two pathways:
- Administratively Determined Incentive (ADI): for smaller projects with pre-set incentive rates based on project category (residential, small commercial, community solar, etc.)
- Competitive Solar Incentive (CSI): for larger projects, awarded through competitive solicitations
The specific incentive designation and paperwork requirements affect the interconnection process and the documentation needed alongside the permit plan set. Design teams need to know which SuSI pathway applies before finalizing the plan set format.
Top New Jersey AHJs for solar permit design
New Jersey has hundreds of AHJs (townships, boroughs, cities, and counties). The highest-volume ones for solar plan set submissions include:
Newark
New Jersey's largest city, with commercial and multi-family solar volume in addition to residential. Newark uses its own permit process through the Department of Engineering. Commercial and larger residential projects generally require PE stamping.
Jersey City
Rapidly growing solar market, particularly for commercial and multi-family rooftop installations. Jersey City uses the CommunityConnect online permit portal.
Elizabeth
Industrial and commercial solar activity, with residential volume across the city. Standard NJ construction code enforcement.
Edison and Woodbridge (Middlesex County)
Two of the largest suburban townships in NJ by population and by solar permit volume. Both are typical suburban NJ AHJs with standardized permit processes.
Toms River (Ocean County)
Very active residential solar market on the Jersey Shore. Ocean County suburban AHJ processes.
Cherry Hill (Camden County)
Central southern NJ suburban solar market. Standard construction code enforcement.
Trenton
State capital, with municipal permit processes for solar.
Atlantic City
Shore market with ACE as the EDC, with residential and some commercial activity.
Camden
Southern NJ urban market with solar activity across residential and commercial.
Beyond these top-volume jurisdictions, dozens of smaller NJ townships and boroughs process solar permits regularly. The general pattern is that most NJ AHJs follow the state UCC with limited local amendments, meaning a well-designed plan set works across many municipalities with minor tweaks.
Common New Jersey solar permit rejection reasons
Whether you are submitting to PSE&G, JCP&L, ACE, or RECO territory, and regardless of which specific AHJ, the same patterns of rejection appear repeatedly:
- Wrong NEC edition cited on plan set general notes: always verify the currently enforced edition with the AHJ
- Structural analysis missing or incomplete: particularly for older homes or unusual roof geometries
- PE stamp missing where required: know the AHJ's threshold and equipment requirement
- Rapid shutdown boundary not shown or labeled correctly: plan set must show the shutdown zone clearly
- Fire code setbacks not met: pathways must comply with the applicable IFC edition
- Utility SLD format not matching EDC requirements: each of the four NJ utilities has slightly different SLD expectations
- Battery storage projects missing NFPA 855 documentation: ESS installations need coordinated NEC + NFPA 855 compliance
- SuSI program documentation missing: the correct incentive designation paperwork must accompany the permit application
New Jersey solar interconnection timelines (general)
Interconnection timelines vary by utility, project size, and current queue depth. General expectations:
- Residential (under 10 kW): typically 2-6 weeks from complete application, depending on utility
- Larger residential (10-25 kW): typically 3-8 weeks
- Small commercial (25-500 kW): typically 6-16 weeks
- Larger commercial and community solar: can extend 4-12+ months depending on interconnection studies required
These are general ranges. Always confirm current timeline expectations with the specific EDC and factor them into your project schedule.
Where outsourced solar design fits into the NJ market
New Jersey EPCs and installers face two operational realities: high demand for residential and small commercial permit plan sets, and four different utility interconnection processes running in parallel. Building sufficient in-house design capacity to handle both consistently requires significant fixed engineering overhead.
Outsourced solar design partners give NJ EPCs the ability to scale plan set output with project volume, absorb turnaround demands from installer clients, and maintain up-to-date expertise across all four utility formats and dozens of AHJ variations without expanding in-house headcount.

Frequently asked questions
Which utilities serve New Jersey for solar interconnection?
Four major electric distribution companies (EDCs) serve New Jersey: PSE&G (northern and central NJ), JCP&L (central and shore NJ), Atlantic City Electric (southern NJ), and Rockland Electric (small territory in Bergen/Passaic). Every solar project connects through one of these based on the project address.
What is the current NJ solar incentive program?
New Jersey's current solar incentive is the Successor Solar Incentive (SuSI) program, administered by NJBPU. It has two pathways: the Administratively Determined Incentive (ADI) for smaller projects with set rates, and the Competitive Solar Incentive (CSI) for larger projects awarded through solicitations.
Do I need a PE stamp on New Jersey solar permit plan sets?
PE stamping requirements vary by AHJ and project size. Commercial solar and larger residential projects (typically above certain kW thresholds set by the local township) generally require PE stamping. Smaller residential may not. Always check the specific AHJ where the project is located.
How long does New Jersey solar interconnection take?
Timelines vary by utility and project size. Small residential typically takes 2-6 weeks from complete application; larger residential 3-8 weeks; small commercial 6-16 weeks. Larger commercial and community solar can take 4-12+ months depending on interconnection studies required. Confirm current expectations with the specific EDC.
Which NEC edition does New Jersey enforce for solar?
New Jersey adopts the NEC as part of the state Uniform Construction Code. The currently enforced edition may vary and does not always match the latest NFPA publication. Always confirm the currently enforced NEC edition with the AHJ where your project is located before finalizing the plan set.
