What a Data Center Freeze Actually Does: Inside East Fishkill’s Three-Year Moratorium

On June 25, 2026, the East Fishkill Town Board voted unanimously to adopt a three-year moratorium on large data centers. The meeting ran nearly two hours, with dozens of residents speaking in support, before the board made it official.

Start with what that vote actually did, because "moratorium" is often used as a synonym for "ban," and it is not one.

A moratorium is a pause on permitting. Businesses that already hold permits can continue operating. Projects mid-construction under a valid permit are generally unaffected. The East Fishkill resolution prohibits the town from issuing new permits or even considering new applications for data centers above a specific threshold: 20 megawatts. That prohibition runs until July 1, 2029. The resolution frames the pause as explicitly temporary, tying it to a waiting period "until the completion of federal and state studies" examining power and water usage, noise, and heat emissions.

Two carve-outs exist. Projects ancillary to an already-permitted use and under 20 MW are exempt. So are projects eligible for an economic-development special permit. Those exceptions preserve room for smaller or economically critical facilities while drawing a clear line against large-scale, standalone data center campuses.

WHAT 20 MEGAWATTS MEANS, AND WHY 1 GIGAWATT IS A DIFFERENT CONVERSATION

The 20 MW threshold is not arbitrary. It tracks closely with thresholds appearing in state-level policy across New York and reflects a rough dividing line between facility scales that have meaningfully different grid and infrastructure footprints.

To put 20 MW in context: a mid-sized hyperscale data center campus runs somewhere between 20 and 100 MW. A suburban office park might draw 5 to 10 MW at peak. A single large hospital might need 5 MW on peak load. At 20 MW, a facility is drawing roughly the equivalent of 15,000 to 20,000 American homes at once, continuously.

The proposal that preceded East Fishkill's moratorium sat at a different scale entirely. Treetop Companies asked the New York Independent System Operator (NYISO) to study the grid impact of a proposed 1-gigawatt AI-processing and cloud-computing center off Donovan Drive. That site would connect to ConEd's grid; NYISO was also studying potential effects on Central Hudson and NYSEG.

One gigawatt is 1,000 megawatts. The Indian Point Energy Center's Unit 3, the nuclear reactor that powered much of the Hudson Valley until its 2021 closure, had a net capacity of roughly 1,000 MW. The Treetop proposal was asking the regional grid to absorb the equivalent of a large baseload power plant's worth of new, continuous demand, concentrated at a single point of interconnection.

That proposal no longer appears on NYISO's interconnection queue, per WAMC. Its scale explains why the town board acted, and why grid operators were studying it in the first place.

WHAT NYISO INTERCONNECTION STUDIES ACTUALLY DO

When a developer wants to connect a large new load or generator to the grid, they submit a request to the relevant grid operator, in this region NYISO. The operator then runs interconnection studies in phases.

The first phase is a scoping study: does the point of interconnection have physical capacity, and what upgrades would be needed? The second phase is a detailed study that models actual power flows, identifies specific equipment requiring replacement or reinforcement, and assigns upgrade costs to the developer. A third phase, the facility study, turns those findings into engineering specifications.

For a 1 GW load, this process is not a formality. Existing transmission lines, substations, and transformers are sized for the loads they were built to serve. Adding 1,000 MW at a single node can require new transmission infrastructure, upgraded substations, and coordinated upgrades across multiple utilities. That is why NYISO was studying effects on ConEd, Central Hudson, and NYSEG simultaneously rather than treating this as a simple single-utility question.

The interconnection queue process takes years. Developers leave the queue for many reasons, including when cost estimates come back higher than the project can absorb.

THE FOUR THINGS THE STUDIES WILL MEASURE

The East Fishkill resolution names four areas for pending federal and state study: power usage, water usage, noise, and heat emissions. These map directly onto the four primary neighborhood-level impacts of large data centers.

Power usage is the obvious one: what load the facility places on the grid, how that load varies over time, and what infrastructure upgrades it requires.

Water usage is less visible but significant. Data centers cool their servers primarily through evaporative cooling systems, chilled water loops, and in some cases direct liquid cooling. A large facility can consume millions of gallons of water per day. In a region dependent on well water or with constrained municipal supply, that draw competes directly with residential and agricultural users.

Noise comes from the mechanical systems: cooling towers, air handling units, backup generators, and transformer hum. These systems run continuously. At scale, they produce persistent low-frequency noise that carries farther than intermittent sources and is harder to mitigate after construction.

Heat emissions are the thermal output that cooling systems exhaust to the surrounding air. A 100 MW facility is, among other things, a 100 MW heat source. Concentrated in one location, that output affects local microclimate, particularly relevant near residential areas or environmentally sensitive land.

WHAT "UNTIL STUDIES ARE COMPLETE" ACTUALLY RESOLVES TO

The resolution ties the moratorium's end condition to study completion rather than a fixed policy outcome. That language matters.

July 1, 2029 is the hard sunset: the moratorium expires on that date regardless of study status. But the resolution also allows the town to act earlier if relevant federal and state studies conclude before that date. In practice, this means the moratorium's effective duration depends partly on timelines set by agencies the town does not control.

At the state level, the picture was still forming as of mid-July 2026. Governor Hochul issued Executive Order No. 62 on July 14, 2026, pausing discretionary DEC permits for facilities of 50 MW or more for roughly one year. The state legislature passed a moratorium bill, S10642/A11560, covering facilities at the 20 MW threshold for one year. That bill was still unsigned at the time of reporting.

East Fishkill is not acting in isolation. A tracker maintained by Interconnected Capital LLC documents more than 100 communities nationwide that have passed moratoriums on data centers. In New York alone, the tracker lists East Fishkill's three-year freeze through July 1, 2029, alongside an 18-month moratorium in Brookhaven, a one-year moratorium in Oneonta, and others.

The pattern reflects a structural mismatch: data center developers are making interconnection requests and site-selection decisions at a pace that outstrips the planning frameworks most municipalities have in place. A moratorium is how a town board buys time to build those frameworks, study the actual trade-offs, and write rules that reflect what the community decides it wants.

East Fishkill voted to pause a specific class of large, high-demand facilities, in a specific permitting window, while regulators and grid operators work through questions that existing land-use permitting was never designed to answer.
