Marion County pauses large commercial data centers for a year with a 50-megawatt cutoff on who still gets through
Marion County approved a 12-month moratorium on new large commercial data centers that use 50 megawatts or more. This temporary halt allows the county to develop new land-use rules to address the significant infrastructure demands, environmental impacts, and operational characteristics of these facilities. Commissioners expressed concerns about electricity, water usage, and noise from hyperscale data centers.
Marion County commissioners have voted to enact a 12-month moratorium on new applications for large commercial data centers, specifically those with an anticipated peak electric load of 50 megawatts or more. The ordinance, approved by a 4-1 vote with initial dissent from Commissioner Kathy Bryant regarding exemptions, temporarily halts the acceptance, review, or approval of rezonings, special-use permits, site plans, development permits, and building permits for these facilities within the unincorporated county.
County Chair Carl Zalak III clarified that the pause is intended to allow the county to establish clear rules before formal applications for "hyperscale" data centers are filed, while exempting smaller plants and IT infrastructure for local businesses, schools, and hospitals. Chief Assistant County Attorney Dana Olesky emphasized that existing ordinances do not adequately address the unique infrastructure demands, substantial electricity and water usage, noise generation, and potential cumulative impacts on groundwater, wastewater systems, and the electrical grid associated with modern data centers.
The moratorium mandates that growth services staff and the Land Development Regulation Commission study critical areas, including Florida Aquifer withdrawals, water and wastewater capacity, electrical infrastructure, land-use compatibility, noise limits, setbacks, cooling practices, and protection of Outstanding Florida Springs. Public sentiment during the hearing was divided, with residents like Renee Andrews of Shiloh advocating for a permanent ban or at least a year-long pause to develop stringent rules, citing concerns over water consumption and grid strain. Conversely, Jack Pritchard of Summerfield urged the county to embrace responsible data center development for its economic benefits and job creation, highlighting advancements in closed-loop cooling technologies.
