Proposed project · Town of Hay River, Dunn County, WI

A different kind of data center

A small, modular project proposed for the Town of Hay River. Built to be quiet, low-impact, and to fit in with the area.

2 MW
Target capacity
0.25–1.5 acres
A small fenced footprint
Low impact
A short build measured in months, fully removable and restorable to prior use

What is being proposed in the Town of Hay River

Nodiac builds small, modular data centers that are fundamentally different than the large-scale projects in the headlines. We use power that's already available on the local grid, instead of building new power plants or new power lines. The capacity we'd use here is power the utility has already identified as “stranded”: capacity on the local grid that isn't being put to good use today, so we're not taking power away from the community. The site itself is quiet and low-profile: a small footprint rather than a sprawling campus, and our site permits will keep it at a modest size.

The project itself is made up of a few standard pieces: chillers that run a closed-loop liquid cooling system with no regular water use (plus some air cooling), a transformer box, and the power and IT module, which resembles a shipping container. These sit on a concrete pad inside a gravel, fenced-in area.

A simple way to think about it: comparing this project to one of the giant campuses in the news is like comparing a family dairy farm to a 5,000-head industrial operation. Both are farms, but they have very different impacts on the community in the short and long term.

For the community

Community benefits

We want this project to bring lasting benefits to your community, and we would rather shape them with you than hand over a fixed list. We are still working through the options with local residents, officials, and the cooperative, and Nodiac plans to formalize whatever we land on in an agreement with the community.

If there is a benefit you'd like to see, tell us

Property taxes and local employment

As with any development, the project pays full property taxes to the county, the Town of Hay River, and the schools. We also expect union labor during construction, and local jobs once the site is running, like groundskeeping, snow plowing, and on-site technicians.

How we build and run it

Development commitments

Beyond the community benefits, here is how we will commit to build and operate the site so we stay a good neighbor. These conditions can be written into the permit, which makes them enforceable and part of the public record.

Quiet operation

At the nearest home, the goal is 40 to 50 decibels or lower. We test noise levels before and after construction.

How this is enforced

These aren't just promises. The project has to go through a public permit process, and the terms we agree to on noise, size and other conditions will be written into the permit. That makes it enforceable and part of the public record.
