SB 4213, the Data Center Water and Energy Transparency Act of 2026, would create a federal reporting framework for large data centers and data center expansions. The bill focuses on facilities with a projected or actual peak demand of at least 25 megawatts and requires operators to report detailed information about on-site electricity use, water use, water sources, power usage effectiveness, water usage effectiveness, and projected future consumption. For new or expanded facilities, the bill also requires forward-looking reports covering the first five years of operation or post-expansion use, including proposals to reduce energy and water consumption.
The bill gives primary reporting authority to states, but if a state does not have its own program to collect the required information, operators must instead report to the Administrator of the Environmental Protection Agency and the Secretaries of Energy and Agriculture. States that do collect the data must submit annual aggregated, anonymized reports to the federal government, and the federal agencies must publish an annual public report on national and regional data center energy and water use, environmental impacts, consumer rate impacts, and best practices. The bill also authorizes states and federal agencies to adopt implementing regulations, assess fees to cover administration, and impose enforcement penalties for noncompliance.
Its impact on state law is to encourage or effectively require states to establish data-collection programs if they want to remain the primary reporting destination for covered data centers. States may charge fees and enforce compliance under their own programs, while local governments may request access to reports affecting them. At the federal level, the bill would add new reporting duties for operators in states without qualifying programs and create a federal public disclosure regime for aggregated data, while protecting proprietary information from publication.
The general sentiment reflected by the bill text is policy-driven and oversight-oriented, with a clear emphasis on transparency, environmental accountability, and planning for infrastructure growth. Because there were no committee transcripts or votes provided, there is no recorded debate or bipartisan support/opposition to gauge, but the structure of the bill suggests an intent to gather standardized information rather than directly regulate data center operations or cap resource use.
The main point of contention likely centers on the burden of compliance and disclosure for data center operators, especially large facilities that consume significant electricity and water. Potential concerns include administrative costs, the scope of federal and state reporting authority, the possibility of fees and daily penalties, and the treatment of proprietary business information. Supporters would likely emphasize the need to understand data center impacts on water supplies, electric grids, and local utility rates, particularly as demand for artificial intelligence and cloud computing infrastructure grows.
The bill would amend the regulatory landscape by creating a new reporting and disclosure regime for large data centers, with state-led collection as the default and federal backstop authority where states lack a program. It would not directly change utility rates or environmental permitting standards, but it would require covered operators to disclose energy and water consumption data, projected growth, and efficiency measures, and it would require states and federal agencies to compile and publish aggregated information. The bill also authorizes fees and civil penalties, giving both states and federal agencies enforcement tools and funding mechanisms to administer the program.
No committee discussion or vote history was provided, so there is no recorded floor or committee sentiment to summarize. Based on the bill text alone, the measure appears to be framed as a transparency and data-gathering proposal rather than a punitive regulation, suggesting a technocratic and oversight-focused approach. The absence of recorded opposition or support in the provided materials means the overall sentiment cannot be measured from debate, but the bill’s design indicates an effort to balance public disclosure with protection for proprietary information.
The likely areas of contention are the compliance burden on data center operators, the threshold for coverage at 25 megawatts, and the division of authority between states and the federal government. Operators may object to detailed monthly reporting, projected-use disclosures, fees, and the $20,000-per-day federal penalty for negligent noncompliance. States may differ on whether to create their own collection programs or defer to federal reporting, and local governments may seek access to information that operators consider sensitive. Another likely point of debate is how much of the collected data should be made public versus withheld as proprietary.
