California Governor Gavin Newsom signed seven bills on Monday designed to increase transparency around data center operations and establish separate regulatory frameworks for the facilities. The legislation responds to growing community concerns about how data centers supporting artificial intelligence development affect electricity costs and water availability across the state.
Three of the bills—Senate Bill 886, Assembly Bill 2383, and Senate Bill 1168—direct the California Public Utilities Commission to create distinct power rates for data centers to recover infrastructure connection costs separately from other utility consumers. This approach aims to prevent data centers from shifting their grid connection expenses to standard residential and business customers. Additionally, Assembly Bill 2383 encourages data centers to increase their use of renewable energy sources.
Four other bills address information gaps about data center environmental and resource impacts. Assembly Bill 1577 mandates monthly reporting of energy consumption figures. Assembly Bills 2619 and 2469 establish water usage disclosure requirements, with the latter making operators financially responsible for necessary infrastructure upgrades. Senate Bill 887 removes categorical exemptions from California’s environmental review process, subjecting all data centers to environmental assessment procedures.
Researchers and environmental advocates have noted the significant lack of publicly available data on data center operations. A recent study by Santa Clara University found that water providers consistently refused to share consumption data citing privacy concerns, and most facilities lacked public environmental impact reports. Experts indicate that as hyperscale data centers increasingly locate in rural areas with smaller water systems and lower-income communities, transparency becomes increasingly critical for understanding local impacts.
While the new requirements represent progress, gaps remain. Water disclosure mandates only apply during permit and licensing applications, potentially capturing usage data from unrepresentative seasonal conditions rather than typical annual consumption patterns. Despite these limitations, observers characterized the legislation as a meaningful signal that lawmakers are monitoring data center development in the state.
