Bill
A 5462
NJ electric utilities must file tariffs for large data centers (≥100 MW) to protect ratepayers, incentivize efficiency, and ensure financial safeguards.
Purpose
- Requires New Jersey electric public utilities to develop and file BPU‑approved tariffs that govern the provision of electricity to "large load data centers."
- Seeks to protect non‑data‑center ratepayers from cost impacts of large new electricity demand, and to incentivize energy efficiency measures (including waste‑heat capture/use) at those facilities.
Key definitions
- "Large load data center": a facility whose primary services are storage, management, and processing of digital data, housing servers, networking, environmental controls, etc., and that has (or is projected to have) a maximum monthly demand of at least 100 megawatts.
Major provisions
- Filing deadline: Each electric public utility must file an application with the Board of Public Utilities (BPU) to establish a tariff for large load data centers no later than 180 days after the bill’s effective date. The BPU may establish rates specific to these customers to guide utility filings.
- Application review: BPU must expeditiously review applications under existing law and approve those that comply.
- Implementation: Utilities must apply the approved tariff to each qualifying large load data center in their service area beginning one year after the bill’s effective date. The BPU has authority to determine whether a facility qualifies.
- Ratepayer protections and financial safeguards: BPU‑established rates, terms, and conditions must reasonably protect ratepayers from increased transmission, distribution, capacity, or energy costs resulting primarily from serving large load data centers. The BPU may require utilities to:
- Ensure new large load customers provide adequate financial guarantees that they will take at least 85% of requested service for a period of not less than 10 years from commencement of service;
- Require demonstration that a proposed project is unique (not duplicative) or identify interdependencies;
- Require deposits or financial security to protect ratepayers if a project ceases operations or takes less service than anticipated during the 10‑year period;
- Impose other protections the BPU deems necessary. The BPU can relax these requirements if a project provides operational flexibility or brings additional energy/capacity online.
Who is affected
- Electric public utilities operating in NJ (must develop and implement tariffs).
- Large data‑center developers/operators (those ≥100 MW demand)—subject to new tariff structures and financial/contractual obligations.
- Non‑data‑center ratepayers (intended beneficiaries of rate protections).
- BPU (responsible for review, approval, and oversight).

Potential impacts (high level)
- Provides regulatory certainty and explicit rate structures for very large data‑center loads, while adding protections for other ratepayers.
- Financial guarantee and deposit requirements could increase upfront/development costs for large data‑center projects.
- Encourages energy efficiency and potential reuse of waste heat, which could support decarbonization/beneficial use strategies.
