New Jersey BPU N.J.A.C. 14:8-4.3: Solar Net Metering Guide

Key Takeaways

• Solar facility generating capacity must not exceed the customer's historical 12-month electricity supply (August 2026).
• Excess generation credits roll over monthly until the end of the annualized period (August 2026).
• At the end of the annualized period, excess kilowatt hours are compensated at the avoided cost of wholesale power (August 2026).
• Customer-generators receive one opportunity to select the start of their annualized period (August 2026).

What are the N.J.A.C. 14:8-4.3 Net Metering Provisions in New Jersey?

New Jersey's net metering framework, outlined in N.J.A.C. 14:8-4.3, establishes the general provisions for solar customer-generators. This regulation sets limits on system sizing, details how excess generation is credited, and defines the process for annual reconciliation (August 2026). It applies to customers generating electricity using Class I renewable energy sources (August 2026).

The table below summarizes the key provisions of N.J.A.C. 14:8-4.3:

How is Solar System Sizing Determined Under N.J.A.C. 14:8-4.3?

For solar installations in New Jersey, the generating capacity of a customer-generator's facility is limited. It must not exceed the amount of electricity supplied by the electric power supplier or basic generation service provider to the customer over a historical 12-month period (August 2026). This ensures that systems are sized to meet the customer's historical consumption rather than for significant over-generation.

What Happens to Excess Solar Generation in New Jersey?

When a customer-generator produces more electricity than they consume in a given month, the electric distribution company (EDC) or supplier/provider credits the excess. The EDC or supplier/provider reduces the customer-generator's bill for the next monthly billing period to compensate for this excess electricity (August 2026). This credit then carries over from monthly billing period to monthly billing period, accumulating until the end of the customer-generator's annualized period (August 2026).

How are Annualized Credits Reconciled and Paid Out?

At the conclusion of the customer-generator's annualized period, any accumulated excess kilowatt hours are reconciled. The EDC or supplier/provider compensates the customer-generator for these excess kilowatt hours at the electric power supplier's or basic generation service provider's avoided cost of wholesale power (August 2026). This means that while monthly credits reduce future bills, the final cashout for remaining excess generation is based on wholesale market rates, not retail rates.

Can You Choose Your Net Metering Annualized Period Start Date?

Yes, customer-generators in New Jersey are provided an opportunity to select their annualized period. The EDC or supplier/provider must offer each customer-generator one opportunity to select a monthly billing period as the start of their annualized period (August 2026). This allows customers some flexibility in aligning their net metering year with their consumption patterns or other financial cycles.

How We Verified These New Jersey Net Metering Rules

We verified the provisions of N.J.A.C. 14:8-4.3 by directly consulting the New Jersey Administrative Code as published on the Cornell Law School Legal Information Institute website (August 2026). This primary source provides the exact statutory language for "N.J. Admin. Code § 14:8-4.3 - Net metering general provisions, annualized period selection" (August 2026). All specific requirements and limitations cited in this article, including the 12-month sizing limitation, monthly credit rollover, and wholesale avoided cost cashout, are quoted verbatim from this official regulatory text.

Navigating Net Metering and Interconnection for Your Solar Project

Understanding net metering rules is a critical step in planning a solar installation. Beyond net metering, you will also need to navigate the interconnection process with your utility.
