Thailand halts 49 data centers as global regulation wave intensifies

From Kentucky to Thailand, governments at every level moved in the same week to impose new controls on data center development, reflecting mounting public concern over the power-hungry facilities' strain on communities and natural resources.

On September 4, Thailand suspended construction of 49 data centers to give officials time to draft new industry regulations, expected within a month, according to Bloomberg. Danucha Pichayanan, secretary-general of the National Economic and Social Development Council, made the announcement after the first meeting of the country's data center supervision commission. Nationwide, 35 data centers are already in operation, while 117 proposed facilities await investment approvals.bloomberg+1

The same day, Tucson, Arizona's first dedicated data center regulations took effect, introducing land use controls, noise limits, environmental reviews, and requirements that developers demonstrate adequate water and power supply and disclose their energy mix. Saudi Arabia also announced new municipal regulations for commercial data centers, standardizing licensing, construction, and operational requirements across the Kingdom.dig+1

US Communities Push Back

In Louisville, Kentucky, the Planning Commission voted on Thursday to recommend regulations that would cap data centers at 500,000 square feet and require conditional use permits for any facility larger than 50,000 square feet, according to Louisville Public Media. The commission went further than initially proposed, recommending that nearly all new data centers undergo a rezoning process with public comment, and mandating closed-loop cooling systems to reduce water consumption. Louisville Metro Council had enacted a 180-day moratorium on data center development in August while the regulations were being finalized.courier-journal+1

In Pennsylvania, West Hempfield Township's Board of Supervisors unanimously approved an ordinance on September 1 limiting data center size and establishing restrictions on proximity to residential and agricultural properties, according to WGAL.wgal

In Oldham County, Kentucky, officials have been working through a protracted regulatory process after a proposed $6 billion data center sparked public backlash in 2025. The county's fiscal court denied proposed regulations in August, opting instead to bring in an outside expert to draft more specific guidelines while keeping an existing moratorium in place.spectrumnews1+1

A Global Reckoning

The simultaneous actions across jurisdictions underscore a shift in how governments treat data centers — from welcomed economic development to major infrastructure projects requiring scrutiny of their energy, water, and land demands. As Tucson's regulatory framework noted, the proliferation of data centers worldwide "is intensifying concerns over energy consumption, land use, water demand, and environmental impacts".dig
