California signs seven data center laws shifting grid costs to operators
Newsom’s package makes data centers pay for transmission upgrades, report energy and water use, and lose blanket environmental exemptions.

The news
California Gov. Gavin Newsom signed seven bills regulating data centers on September 21, a package his office called the most comprehensive data center laws in the nation. The measures cover electricity costs, energy and water reporting, and environmental review.
The centerpiece, SB 886, requires the California Public Utilities Commission to adopt new tariffs by January 1, 2028, under which transmission-level data centers bear the full cost of the transmission upgrades they need. It applies to interconnection agreements signed on or after January 1, 2027, and includes a 10-year early termination fee if a facility leaves the system or falls short of its projected demand, according to a National Law Review analysis. AB 2383 requires data centers to pay incremental generation costs for at least 10 years and comply with state clean energy procurement rules.
AB 1577 requires operators to report location, size, power usage effectiveness and on-site generator fuel use to the state Energy Commission. AB 2469 and AB 2619 add water-use disclosure requirements, including projected water demand as a condition of local approval. SB 887 removes blanket environmental review exemptions for data centers, and SB 1168 directs an assessment of rate structures to prevent cost-shifting to other customers.
The package marks a reversal: CalMatters noted that Newsom vetoed a data center water disclosure bill in 2025 over concerns about slowing AI growth. The Data Center Coalition warned that further regulation could push the industry elsewhere.

Why CEOs should care
These laws raise the all-in cost of building large data centers in California, and those costs tend to flow downstream. Hyperscalers and colocation providers will price in transmission upgrades, long-term generation commitments and termination fees. Companies that need in-state capacity for latency or data-residency reasons should expect that to show up in contract pricing over time.
The disclosure requirements also create public data on energy and water use per facility. That gives customers, investors and local officials new ways to compare providers, and it will matter for companies with sustainability reporting obligations that include their cloud footprint. Expect other states facing local opposition to borrow from California’s template.
What's next
Key dates: AB 2383 tariffs are due January 1, 2027, and SB 886 tariffs by January 1, 2028. The CPUC rulemaking will determine the actual cost burden.
