Electrical Demand Response Programs in New Jersey

Electrical demand response programs in New Jersey allow utilities, grid operators, and enrolled customers to reduce or shift electricity consumption during periods of peak grid stress. These programs operate under frameworks established by the New Jersey Board of Public Utilities (NJBPU) and coordinated through PJM Interconnection, the regional transmission organization that manages the bulk power grid serving the state. Understanding how these programs are classified, triggered, and compensated is essential for commercial, industrial, and large residential customers whose electrical infrastructure interacts with grid-level demand signals.

Definition and scope

Demand response (DR) refers to deliberate, pre-agreed reductions in electricity usage by end-use customers in response to grid reliability needs or price signals. In New Jersey, DR programs fall under two primary administrative structures: programs administered directly by New Jersey's electric distribution companies (EDCs)—PSE&G, Jersey Central Power & Light (JCP&L), Atlantic City Electric, and Rockland Electric—and programs operating through PJM's wholesale electricity markets (PJM Interconnection, Demand Response).

The NJBPU regulates retail-level DR programs under the New Jersey Electric Discount and Energy Competition Act (N.J.S.A. 48:3-49 et seq.) and through its Energy Master Plan framework. Wholesale participation is governed by PJM's tariff and the Federal Energy Regulatory Commission (FERC) Order 745, which established compensation rules for demand response resources in energy markets.

Scope limitations: This page addresses demand response programs applicable to customers in New Jersey served by PJM-connected utilities. It does not cover demand response mechanisms in states outside New Jersey, Federal procurement programs where New Jersey participation is incidental, or behind-the-meter storage programs addressed separately at New Jersey Solar and Battery Storage Electrical.

How it works

New Jersey demand response programs operate through a structured sequence of enrollment, dispatch, and settlement:

Enrollment — A customer or aggregator registers load reduction capacity with the EDC or directly into a PJM market product. Minimum enrollment thresholds vary by program; PJM's Emergency Load Response Program historically required a minimum of 100 kilowatts (kW) of curtailable load per resource.
Baseline establishment — The program operator calculates a Customer Baseline Load (CBL), representing what a participant would have consumed without curtailment. PJM uses a ten-of-ten methodology, averaging the ten highest load days from the preceding 45 business days (PJM Manual 11: Energy & Ancillary Services Market Operations).
Event dispatch — Grid operators or EDCs issue a dispatch signal during peak demand periods, capacity emergencies, or high-price intervals. Participants reduce or shift load within the agreed general timeframe, typically within 30 minutes for emergency programs or two hours for economic programs.
Metering and verification — Actual consumption during the event is measured against the CBL. New Jersey's Advanced Metering Infrastructure (AMI) rollout, mandated through NJBPU orders, supports interval-level metering at 15-minute resolution for large commercial and industrial accounts.
Compensation and settlement — Participants receive capacity payments, energy payments, or bill credits depending on program type. Under FERC Order 745, wholesale demand response resources receive the Locational Marginal Price (LMP) for verified reductions in the energy market.

Common scenarios

Commercial office buildings — Large commercial tenants enrolled in curtailment programs shed non-critical HVAC loads, lighting, and plug loads during PJM capacity events, typically occurring 10 to 15 times per summer season in high-stress years.

Industrial facilities — Manufacturing operations with flexible production schedules shift energy-intensive processes (compressors, chillers, arc furnaces) outside peak windows. These participants frequently enroll in PJM's Capacity Performance (CP) product, which carries financial penalties for non-performance during grid emergencies.

Aggregated small commercial accounts — Curtailment service providers (CSPs) aggregate loads below the PJM minimum threshold, bundling 50 or more accounts to meet market participation requirements. CSPs operate under agreements with both the customer and PJM.

Retail EDC programs — PSE&G's Pay-for-Performance incentive structure and JCP&L's commercial demand response offerings compensate enrolled customers directly through bill credits calculated against measured curtailment, independent of wholesale market participation.

Emergency vs. economic dispatch — a key distinction:

Feature	Emergency Demand Response	Economic Demand Response
Trigger	Grid reliability emergency	High LMP price signal
Notice period	As short as 30 minutes	Typically same-day or day-ahead
Compensation basis	Capacity payment + LMP	LMP only
Example program	PJM Emergency Load Response	PJM Economic Load Response

Decision boundaries

Several structural factors determine whether a facility is eligible, appropriately incentivized, or operationally constrained within New Jersey demand response frameworks.

Electrical infrastructure compatibility — Participation requires interval metering and in some programs, automated control systems or building management system (BMS) integration capable of receiving dispatch signals. Facilities without AMI-compatible metering or automated load control may face enrollment barriers. Panel capacity and electrical panel upgrade considerations can affect whether automated DR controls can be installed without service modifications.

Capacity Performance obligations — PJM's CP construct, implemented following the 2014 polar vortex grid stress events, imposes financial non-performance charges on resources that fail to deliver during declared emergencies. The penalty structure is defined in PJM's tariff and can reach multiples of the capacity clearing price. Facilities with process constraints that prevent reliable curtailment should assess CP risk before committing capacity.

Interconnection and metering coordination — Customers enrolled in both DR programs and distributed generation (DG) must coordinate metering configurations with their EDC to ensure accurate CBL measurement and avoid double-counting generation exports as demand reductions. The New Jersey electrical utility interconnection framework governs the interconnection side of this boundary.

Safety and code boundaries — Load curtailment strategies must not compromise life-safety systems. The National Electrical Code (NEC, NFPA 70 2023 edition), as adopted in New Jersey under N.J.A.C. 5:23, and NFPA 70E (2024 edition) workplace electrical safety standards define which circuits—emergency lighting, fire alarm, elevator controls—are categorically excluded from any curtailment automation. For a detailed safety risk framing, see the conceptual overview of New Jersey electrical systems.

Program stacking — New Jersey customers may participate in both retail EDC programs and wholesale PJM markets, but the NJBPU and PJM impose rules against double-compensation for the same load reduction event. Aggregators and large customers must document enrollment boundaries to remain compliant.
