AB 1099 Wisconsin Assembly · 2025-2026 Regular Session

Relating to: moratorium on data centers.

This bill establishes a moratorium on operating new data centers in the state unless specific conditions are met, directly affecting companies that build or operate large-scale digital storage and processing facilities. It requires the creation of a statewide planning authority and mandates that data centers cannot shift their energy or water costs to residential customers. The legislation also includes requirements for mandatory public reporting of resource usage, environmental safeguards, 100% renewable energy from newly built projects, prevailing wage standards for construction workers, and prior approval by local voters before a data center can be built. Additionally, it prohibits financial subsidies for data centers, bans nondisclosure agreements between data centers and local officials, and restores public utility planning authority.
