July 20 (Reuters) – A growing number of governments, regulators and cities around the world are moving to freeze, restrict or ban new data centre construction, as concerns mount over electricity costs, strained ‌water supplies, land scarcity and the burden on local communities from the infrastructure powering the AI boom.

Below ‌are some key examples:

NEW YORK STATE, U.S.

Governor Kathy Hochul imposed a one-year construction moratorium on data centres using 50 megawatts or more of ​power, making New York the first U.S. state to enact a full moratorium.

During the freeze, the state’s Department of Environmental Conservation will not issue new discretionary permits while officials develop standards to assess the environmental impact of data centres.

MAINE, U.S. (vetoed)

Governor Janet Mills vetoed bipartisan legislation that would have enacted an 18-month moratorium on new data centres using more than 20 ‌MW of power.

Mills said she supported a ⁠moratorium in principle but objected to the bill’s failure to carve out an exception for a specific project in the Town of Jay.

MONTEREY PARK, CALIFORNIA, U.S.

Residents voted to permanently ban ⁠data centres in Monterey Park in June 2026, becoming the first U.S. city to do so at the ballot box, following public backlash over a planned facility.

AMSTERDAM, NETHERLANDS

The Dutch capital imposed a one-year moratorium on new data centre developments in 2019. ​In April ​2025, it barred new data centres or expansions in the ​municipality until at least 2030.

Separately, the Dutch government’s ‌2022 hyperscale ban restricts large facilities to two designated locations nationally, though Microsoft won approval in January 2026 for a project split into three towers, each individually below the size threshold.

DUBLIN, IRELAND (restriction now lifted)

Ireland’s grid operator effectively blocked new data centre connections around Dublin from 2021 after warnings that the facilities were straining the grid.

The freeze ended in December 2025, with new connections now required to bring their own on-site power generation.

AUSTRALIA (planned legislation)

Prime Minister Anthony Albanese ‌said Australia would establish a government office to manage the development ​of AI standards, including rules for large data centres covering their location, ​power and water use, with legislation due early ​next year.

Australia does not currently have specific AI laws, relying instead on a range of ‌privacy and consumer protection laws and a voluntary ​AI ethics framework.

DENMARK

Denmark’s government has ​introduced a draft bill to its parliament that would give new data centres the lowest priority for power grid connections amid growing capacity shortages.

The proposed law, backed by a broad cross-party agreement representing 80% of ​the parliament, would prioritise households, healthcare, ‌industry, transport and renewable energy projects instead.

Denmark’s power grid has come under strain from a surge ​in electricity demand and connection requests, including from large data centres.
