A 4096 New Jersey General Assembly · 2026-2027 Regular Session

Requires data center owners and operators to submit semi-annual water and energy usage reports to BPU.

This bill requires data center owners and operators in New Jersey to submit semi-annual reports to the Board of Public Utilities (BPU) detailing their water and energy usage. The reports must include specific metrics like total energy consumption (including cooling), water sources, and efficiency calculations such as "water usage effectiveness" (water used per computing task) and "energy reuse factor" (heat reused outside the facility). Data centers that receive state financial incentives must also report additional sustainability metrics, including average cooling temperatures and renewable energy usage. The law applies to all data centers operating in the state, with initial reports due 3-6 months after the bill takes effect.

MODERATE
The First Reprint of A4096 makes several substantive amendments to New Jersey's data center water and energy reporting bill. Most notably, it adds an exemption for health care facilities' internal data centers, changes the three-year reporting clock from a fixed date tied to the law's effective date to a per-facility clock starting when each data center first submits a report, expands water usage reporting to include peak daily measurements, and broadens the term 'municipal water supply' to 'public water system' with new identification requirements. A savings clause was also added to clarify that the confidentiality provisions do not override other state disclosure laws.
SCOPE

Added an exemption from the definition of 'data center' for facilities used primarily for internal operations by a licensed health care facility or provider, as long as they do not operate as a commercial data processing or colocation facility for an unaffiliated entity.

Expanded the list of co-sponsors from three members (Brennan, Sampson, Walker) to twelve members, adding Onyema, Kearney, Peterpaul, Donlon, Morales, Bhalla, Quijano, Swain, and Tully.

TIMELINE

Changed the three-year reporting period from being measured from the effective date of the act to being measured from the date each individual data center first submits a water and energy usage report, regardless of when it commenced operation or when the act took effect.

REQUIREMENT

Expanded water input reporting from 'total water input' to 'total and peak daily water input,' requiring data centers to report their peak daily water consumption in addition to total volume.

Added a new requirement that if a data center uses water from a public water system, it must provide the name of that public water system and any water service agreements between the public water system and the data center.

DEFINITION

Replaced the term 'municipal water supply' with 'public water system' in the water source reporting requirements, broadening the category of water sources covered.

ENFORCEMENT

Added a savings clause (new subsection d.(2)) stating that nothing in the section abridges or alters the disclosure obligations of any state agency under other laws, including the Open Public Meetings Act and the Open Public Records Act, and clarifies that the board's confidentiality obligation applies only to information submitted for compliance with subsection c.
