**New York Halts Large Data Centre Projects in Environmental Review**
New York State has implemented a statewide pause on approvals for new large-scale data centre projects as it works to develop comprehensive regulations addressing electricity demand, environmental impacts, and infrastructure costs. The moratorium, announced by Governor Kathy Hochul, applies to new facilities and expansions expected to consume at least 50 megawatts (MW) of power. It is set to last up to one year, marking the first time New York has imposed a statewide suspension on data centre developments of this magnitude.
The executive order specifically targets projects supporting cloud computing, artificial intelligence, data storage, content delivery, and streaming services. While incomplete applications for state discretionary permits are paused, those already deemed complete before July 14 are exempt from the halt. Local government permits and facilities dedicated to manufacturing, academic research, quantum research, biomedical research, education, or medical care are excluded from the order.
Governor Hochul stated that the pause is necessary to address concerns about rising utility bills, natural resource depletion, and uncertainty for residents. She also indicated plans to pursue legislation that would remove sales tax exemptions currently enjoyed by large data centres.
**State Reviews Environmental and Grid Requirements**
As part of the moratorium, state agencies are preparing a Generic Environmental Impact Statement to evaluate the consequences of data centre construction and operations. The review will scrutinise electricity demand, water usage and quality, air quality, noise, and effects on disadvantaged communities. Officials noted that existing regulations do not fully account for the water use and wastewater management challenges posed by modern data centres. The assessment will also examine potential impacts on aquifers, surface water, and public infrastructure.
With nearly 12 gigawatts (GW) of proposed data centre load currently in the New York Independent System Operator’s (NYISO) connection queue—and more than 8GW added in 2025 alone—the state is confronting increasing pressure on its grid. While the queue reflects projected demand rather than guaranteed capacity, NYISO has begun incorporating over 2.5GW of new large-load demand into its system forecasts.
Large-scale data centre projects often necessitate substantial grid upgrades, including new substations, transmission lines, transformers, and cables. According to the International Energy Agency, such developments frequently face constraints related to grid connections and regulatory approvals, with new transmission lines taking four to eight years to complete in advanced economies. Waiting times for critical equipment like transformers and cables have doubled in the past three years, and the IEA estimates that around 20% of planned data centre projects could face delays unless grid constraints are resolved.
**Regulators Examine Costs and Approval Rules**
The executive order highlights concerns over financial risk for consumers when utilities invest in grid infrastructure for projects that may later be delayed, scaled back, or cancelled. The state has indicated that large electricity users should bear the cost of grid upgrades through a “beneficiary pays” model rather than shifting the burden to other utility customers. The Department of Public Service will explore safeguards to prevent stranded assets associated with underutilised projects.
Regulators are also considering the establishment of a Grid Acceleration Fund, with potential measures including upfront developer contributions, demand-response participation, new generation capacity, distributed energy resources, battery storage, and insurance mechanisms to cover project risks. These proposals remain under review and are not yet binding requirements.
New York’s average residential electricity price rose to 25.69 cents per kilowatt-hour in April 2026, a year-over-year increase that federal data does not directly attribute to data centres. The state’s actions align with a broader federal review led by the Federal Energy Regulatory Commission, which is examining how large electricity users connect to regional grids. In June, FERC ordered six regional grid operators, including NYISO, to justify their connection practices and propose revised tariff structures.
A separate legislative proposal, the Responsible Data Center Development Act, would introduce a 20MW threshold for a one-year moratorium and impose longer-term requirements for large data centres. The bill also calls for separate electricity and water service classifications and public hearings before permits are issued. Although the bill is currently active, its provisions are not yet law.
**Community and Industry Responses**
The executive order directs Empire State Development to create a Community Investment Framework within 60 days. This framework will outline infrastructure investment, electricity affordability, wastewater services, broadband access, local hiring, apprenticeships, labour standards, and project reporting. It is intended to guide negotiations between local authorities and developers rather than enforce uniform statewide compensation terms.
A recent Reuters/Ipsos poll found that while one-third of Americans support the pace of data centre development, most oppose such facilities being located near their communities. Digital Realty, a data centre operator, argued that the pause could redirect investment elsewhere and said the company is committed to collaborating with policymakers on responsible growth strategies. Doug Adams, CEO of NTT Global Data Centers, emphasised the need for clearer information about employment, investment, and resource use, noting that increased scrutiny reflects public interest in understanding local impacts.
Dozens of state legislatures have proposed measures related to data centre electricity use, environmental effects, and infrastructure demands. New York is the first state to enact a statewide moratorium on large new data centres, while Maine Governor Janet Mills previously vetoed similar legislation.
**FAQs**
**What is the New York data centre moratorium?**
It is a one-year pause on state environmental approvals for new large data centres and expansions consuming at least 50MW of electricity. The pause allows the state to review environmental and grid-related impacts before developing permanent regulations.
**Which data centre projects are affected?**
The moratorium applies to new facilities and expansions designed to consume at least 50MW. Projects supporting cloud computing, AI, data storage, content delivery, and streaming are included.
**Which projects are exempt?**
Facilities used primarily for manufacturing, academic research, quantum research, biomedical research, education, or medical care are excluded. Local government permits are also unaffected.
**Why is New York implementing this pause?**
The state aims to evaluate electricity demand, environmental effects, water use, noise, and impacts on disadvantaged communities. The review seeks to ensure that grid infrastructure and regulatory frameworks can accommodate growing data centre demand.
**How might this affect the industry?**
Some operators warn that the pause could divert investment to other regions. However, others acknowledge that increased scrutiny reflects a broader public interest in understanding how data centres affect local communities and infrastructure.
**What happens after the moratorium?**
The pause will remain in effect until the state completes its review and finalises environmental findings, up to one year from the order. Public hearings and comment periods will be part of the process before permanent rules are established.
**Conclusion**
New York’s suspension of large data centre approvals reflects a growing trend of governments grappling with the energy, environmental, and infrastructure challenges posed by digital expansion. By conducting a thorough, public review of the impacts and costs associated with data centres, New York is positioning itself to balance technological innovation with community and environmental interests. The outcome of this moratorium could influence how other states and regions approach data centre regulation in the years to come.
