An Act to create 196.20 (10), 196.492 and 299.70 of the statutes; Relating to: certain requirements related to data centers.

Impact

One of the primary implications of AB840 is the requirement for data centers to utilize closed-loop cooling systems, which recycle a fixed volume of water. This provision is intended to conserve water resources in the state. Additionally, the bill's stipulation that renewable energy facilities primarily serving a data center must be located on-site pushes for more environmentally-friendly energy solutions, promoting sustainability within the industry. However, these regulations may involve additional costs for data center operators.

Summary

Assembly Bill 840 aims to regulate data centers in Wisconsin by implementing specific requirements that address water usage, construction, and energy sourcing. The bill defines data centers and establishes a framework for their operation, including mandates for water cooling systems, renewable energy facility location, and reporting obligations regarding water consumption. This legislation seeks to ensure that data centers operate sustainably and responsibly while minimizing their environmental impact.

Contention

Debate surrounding AB840 likely focuses on the balance between ensuring environmental sustainability and not stifling the growth of the technology sector. Proponents argue that these regulations will lead to more responsible management of local resources and energy efficiency. Conversely, opponents may raise concerns about the burden these regulations could impose on businesses, potentially hindering investment in the state and impacting the competitive landscape. The extent to which these regulations will affect operational costs and the willingness of companies to establish data centers in Wisconsin remains a central point of discussion.
