Existing sites and projects already in the pipeline would not be covered.
π Data center rules
Fort Worth City Council adopted new application requirements for data centers, including showing state power grid approval before applying for city permits, and new water and wastewater design rules. It also created a Data Center and Infrastructure Commission, with 11 voting members, to study power, water, land use and money effects. Its report is due November 3, 2026.
β Turned down
