California Mandates Data Centers Disclose Energy, Water Use

California's new legislation requires data centers to disclose energy and water usage, impacting costs and compliance.

What Happened
California Governor Gavin Newsom has signed a series of bills into law on September 23, 2026, demanding greater transparency and accountability from data centers regarding their energy and water usage. These laws mandate data centers to report their energy consumption and water use to local governments and pay for grid infrastructure upgrades. The legislative package aims to address the growing concerns of the communities affected by the rapid expansion of data centers, particularly their impact on local resources and infrastructure.

The newly enacted laws include SB 1168, which directs the California Public Utilities Commission to ensure data centers contribute to transmission and distribution upgrades. SB 886 and SB 887 require data centers to cover infrastructure upgrade costs and undergo environmental reviews, while AB 1577 demands monthly reporting of energy consumption to the California Energy Commission. Additionally, AB 2383 incentivizes onsite clean energy use, and AB 2469 and AB 2619 focus on water use oversight, requiring assessments and scarcity plans.

What This Means for Your Business
For stakeholders in the architecture, engineering, construction, and manufacturing (AECM) sectors, these changes present both challenges and opportunities. Compliance with the new regulations will necessitate investments in reporting systems and infrastructure upgrades, potentially increasing operational costs. However, this could also lead to new business opportunities for firms specializing in sustainable construction and energy-efficient technologies.

The focus on clean energy and water management may also drive innovation and competitive differentiation in the market. Companies that proactively adopt these changes could benefit from a favorable position in government contracting and procurement processes, particularly as environmental compliance becomes a critical factor in bid evaluations.

What US Operators Should Watch
Data center operators and businesses involved in construction and infrastructure should closely monitor the implementation timelines for these laws. Key deadlines include the immediate requirement for monthly energy consumption reporting and the upcoming need for water use assessments during the permitting process. Compliance officers and procurement directors must stay informed about the California Energy Commission's guidelines and the Public Utilities Commission's infrastructure requirements.

As these regulations take effect, understanding the nuances of each bill and preparing for audits and inspections will be crucial for maintaining compliance and securing future contracts. With California setting a precedent, similar legislation may emerge in other states, making this a pivotal moment for nationwide operators to align their strategies with sustainable practices.
