Not every data center is the same. This proposal is designed for Ames.

This is the question we hear most, and it points to a real constraint. Ames residents have rightly noted the grid is running with little headroom. That is exactly why the project is phased: it starts at 3 MW, steps up to 6 MW, and only approaches 25 MW at full buildout over roughly ten years, as customer demand actually materializes. It is not a single massive load switched on at once.

Electrical infrastructure upgrades tied to the project would be funded by Lightedge and its partners, structured so existing Ames utility customers are not responsible for the costs of serving the facility.

Still being decided: capacity, transmission, and the terms that protect ratepayers are part of the City’s open review. They will be tested by Ames Electric Services and the Council, not asserted by us.

Unlike many large data centers that rely on evaporative cooling, this facility is designed around chillers and efficient fans that cool with air. As designed, it would not require daily water consumption for cooling.

For scale: Lightedge’s existing Altoona facility averages about 1,267 gallons a day on the city utility bill. That is roughly 5% of the 25,000 gallon threshold at which Iowa even requires a Water Use Permit. A hyperscale campus using evaporative cooling can draw millions of gallons a day by comparison.

Where Lightedge uses a closed-loop chilled-water system, the loop contains water, not a water/glycol mix. Water quality is tested quarterly by a vendor, and treatment chemicals are added only as needed based on those test results. The chilled-water piping is not designed for routine draining, blowdown, or wastewater discharge; draining would only occur for unusual work such as system decommissioning, replacing a section of piping, or repairing a damaged section.

Lightedge also operates cooling designs that do not use a closed-loop chilled-water system at all. The proposed Ames facility should be understood in that same practical context: cooling design is selected for the site, the load, and efficiency, not as a high-water-use evaporative system.

Still being studied: an environmental review of the site, including proximity to nearby waterways, is part of the City process.

We’ll be straight: data centers are not large direct employers, and the staffing on site for a facility like this is small. If the test is “hundreds of jobs,” that is not what this is.

The value is different. It keeps modern, compliant infrastructure local, serving ISU Research Park companies, healthcare providers, financial institutions, and manufacturers already in Ames who otherwise send that work out of the region. It adds to the tax base, supports investment in fiber and telecom capacity, and funds STEM education partnerships with Ames schools.

Lightedge’s position is that existing Ames utility customers should not pay for project-specific electrical upgrades. Electrical infrastructure tied to the project would be funded by Lightedge and its partners, with agreements structured so the costs of serving the facility fall on the developer rather than existing utility customers.

Worth saying plainly: the specific terms are subject to City Council approval. If they do not protect ratepayers, that is a reason for the Council to say no, and the review exists precisely to check that.

No. This is edge colocation: a single story building on about 10.86 acres where regional companies place and manage their own equipment. At 3 to 25 MW phased, it is one to two orders of magnitude smaller than the 50 to 1,000+ MW hyperscale campuses built for global workloads. Lightedge has operated this model in Altoona for years as part of the corporate ecosystem there.

The site sits in a Planned Industrial zone on airport property, directly west of Sigler Companies, an industrial setting rather than a residential one. The cooling equipment is cooled by air and selected to run quietly, with placement, setbacks, and a single story design intended to contain sound on site. Current projections put sound at the property line in the range of ordinary commercial background noise, roughly 45 to 55 dBA. Lighting would meet dark sky standards, using full cutoff fixtures that direct light downward to keep it from spilling onto neighbors.

Backup generators are part of responsible colocation design because hospitals, financial institutions, manufacturers, and research organizations need continuity during utility interruptions. The question is not whether resilient backup power exists; it is how it is specified, enclosed, tested, and reviewed for the site.

Generator enclosure options commonly fall into these sound ranges, measured about 7 meters from the equipment:

• Standard weather-protective enclosures: approximately 75 to 85 dBA.
• Sound-attenuated enclosures: approximately 65 to 75 dBA, common for hospitals and commercial centers.
• Ultra-quiet enclosures: approximately 50 to 65 dBA, commonly requested for strict residential zoning, urban data centers, or medical facilities near housing.

That range is in line with a colocation development plan because backup power is intermittent, not the facility’s normal operating source, and because enclosure selection, setbacks, equipment orientation, and the City’s sound review can be used together to keep the project compatible with its planned industrial airport setting.

A professional sound study would be completed as part of the City’s review.
