California mandates data centers disclose water and electricity use

California has enacted new legislation that requires data centers to disclose their water and electricity usage. This move is part of a broader effort to increase transparency and give communities more insight into how data centers affect local resources. The legislation mandates that data center operators provide detailed reports on their energy and water consumption, starting next year. This will allow scientists and the public to better understand the environmental impact of these facilities.

The new rules will also direct the California Public Utilities Commission to create separate power rates for data centers. This is intended to prevent data centers from passing on the costs of new infrastructure to other consumers. By creating separate rates, the state aims to ensure that the costs associated with connecting data centers to the grid are borne by the data centers themselves, rather than being distributed across all consumers.

The legislation includes several other provisions aimed at increasing transparency and accountability. For example, Assembly Bill 1577 requires monthly reporting on data centers' energy consumption. Assembly Bill 2619 and Assembly Bill 2469 require water disclosures and make data center operators responsible for covering the costs of infrastructure upgrades needed to serve them. Senate Bill 887 eliminates categorical exemptions from the California Environmental Quality Act for data centers, ensuring that they are subject to environmental review.

The new disclosure requirements will have significant implications for engineers and operators of data centers in California. On one hand, the increased transparency will help in understanding the environmental impact of data centers and in planning for future infrastructure needs. On the other hand, the regulatory burden will increase, as data centers will need to invest in systems to track and report their water and electricity usage accurately.

The legislation also aims to push data centers to use more renewable energy. This will require data center operators to invest in renewable energy sources and to integrate them into their operations. While this will increase the upfront costs for data centers, it may also lead to long-term savings and reduce the environmental impact of these facilities. Overall, the new legislation represents a significant step towards increasing the transparency and sustainability of data center operations in California.
