Why New York State Imposed a Data Center Moratorium

New York State has been given up to a year to decide how to take the necessary action. environmental measurement of a data center. On July 14, Governor Kathy Hochul ordered the first statewide moratorium on new large-scale installations, putting some of the Artificial intelligence boom on hold while the state figures out how to measure their enormous demands for electricity and water and their effects on surrounding communities.

This could make New York a test for the rest of the country. Data centers have been around for decades, but newer facilities are arriving at a scale and speed that many utilities and regulators were not prepared to handle.

The moratorium covers proposed facilities capable of consuming at least 50 megawatts whose applications for certain state permits have not yet been deemed complete. Over the next year, the state Department of Public Service will prepare an environmental impact study examining energy demand, water use and quality, air pollution, noise and disproportionate impacts on disadvantaged communities. The New York Department of Environmental Conservation will also examine whether existing water withdrawal rules in the state accurately account for data center demands.

Data centers host thousands of servers that operate around the clock to provide digital services ranging from chatbot responses to music and video streaming.

Almost all electricity that reaches computer equipment eventually turns into heat. The servers themselves consume most of the energy; fans, pumps, coolers, and cooling towers add additional load while ensuring servers don’t overheat. Depending on the system, this process can also consume large amounts of water.

Experts say the first, and perhaps hardest, step for New York is to understand how much water and energy data centers use. Currently, detailed facility-level figures are often not publicly available or are reported inconsistently.

Fengqi youprofessor of energy systems engineering at Cornell University, says a solid foundation of data is essential for developing a regulatory framework.

“In my opinion, data and transparency [are] That’s the hard part,” he says. “If you get the data, we’re very good at using it to make decisions. But if the data is not complete enough or even misleading, this could be a challenge.

Even if New York can accurately measure the effects of data centers on energy supplies, water resources, and air quality, those numbers won’t indicate an obvious set of rules. Eric Sjöstedta postdoctoral researcher at Virginia Tech, cautions against a “blanket solution” that overlooks the extent to which an installation’s effect can vary depending on location, power source and cooling system. “When we talk about data centers generally, it’s important to recognize that, yes, there are some general trends that we can draw out of them and how we look at their impacts,” he says, “but they are very heterogeneous.”

Most data centers draw their electricity from the power grid. On the scale covered by New York’s order, a single installation can consume as much energy as tens of thousands of homesand utilities may need to build new infrastructure to serve them. New York is separated Boosting the development of New York The initiative examines how to keep these costs from falling on ordinary customers and make data centers “bear their own burden,” according to a news release from the governor’s office.

The environmental effect also depends on how this electricity is produced. New York could ask data centers to “BYOP” (bring your own power), You says. But on-site generation could worsen air pollution if the state doesn’t regulate the energy source.

“It really depends on where you produce that energy,” he says. “It could come from natural gas, coal, nuclear, solar, wind, etc. Their carbon footprints are very different.”

The diesel generators that most data centers use as backup also raise air pollution concerns, particularly when facilities are located close to homes. And generators and cooling equipment can create persistent noise.

Water presents a different accounting problem. Electricity production that powers a facility can create an off-site water footprint. On-site, a data center can take water and return much of it to the source or consume it through evaporation. You invoke the old real estate adage: “Location, location, location.”

In southern Nevada, for example, the state water authority supported a moratorium on evaporative cooling in new commercial and industrial buildings because of the strain it places on the region’s limited water supply. But closed-loop cooling can use much more energy, Sjöstedt says, so the tradeoffs are different depending on which resources are locally more limited.

Jonathan Koomeyan energy efficiency researcher, says the choice of site is the crucial question.

“We need data centers. So the question is: where should we place data centers and how should their external costs be mitigated so that they have minimal impact on the surrounding community and society as a whole?”

New York will spend the next year trying to answer that question. You say the framework the state developed could become a model for other places facing the same rush to build data centers.
