Ames, Iowa Has Not Decided Yet. A Data Center Is Proposed on City Land, and Residents Can Still Apply to the Committee That Advises the Vote.

The request is narrower than the hyperscale campaigns fought over elsewhere in Iowa. In its letter to the Council, LightEdge described itself as a Des Moines based company serving more than 1,400 customers with more than 400 employees and data centers across Minnesota, Iowa, Nebraska, Missouri and Texas, and said it already serves about a dozen customers in the Iowa State University Research Park. City staff called the proposal "a smaller regional scale facility compared to hyperscaler multi-building campuses." The site is roughly 10.86 acres on Aviation Way, west of the Sigler Companies property, currently farmed and identified in the 2020 Airport Master Plan as suitable for non-aeronautical use.

What LightEdge needs from Ames is not a rezoning and not a special use permit. The land is already zoned Planned Industrial, and staff noted the Zoning Ordinance does not define a data center use at all, so the use falls into existing industrial categories and is allowed subject to site development plan review. What the company needs is a long term ground lease of airport land, which first requires the City to ask the Federal Aviation Administration to release the parcel from its federal obligations and approve a land use change, with proceeds spent only for the benefit of the airport. It also needs an electric service arrangement, because the distribution equipment in place today can serve about 3 megawatts and no more.

Staff put numbers on that. Serving phase two at the airport would take roughly $4 million in electric infrastructure and phase three roughly $12 million more, including a 69 kV transmission extension and a new substation, with conductors likely buried under the runway because overhead lines cannot cross the approach paths. LightEdge is also weighing two private sites in Ames, the former Danfoss property at 300 Airport Road and a lot on Bailey Avenue, which staff priced at roughly $8 million and $20 million for the same two phases. Staff warned that a private site would leave the City without a lease and so with "a lessened ability to place contractual obligations or limitations on the project, such as constraints on water consumption, noise, light."

Ames has run its own electric utility since 1896 and serves more than 28,000 customers. That makes the usual data center power argument unusually concrete, because there is no investor owned utility in the middle. The people who would pay for new capacity are the people who vote for the Council that sets the rates.

The June staff reports laid out the position plainly. Ames belongs to the Midcontinent Independent System Operator, which requires a member utility to hold firm generating capacity equal to 109 percent of its five year average peak day demand. The City and Iowa State University combined five year average coincident peak for planning year 2025-26 is 148.8 megawatts, or 166.3 megawatts with reserve margin and losses. Ames and Iowa State generation plus power purchase agreements come to 165.5 megawatts, which staff put at 99.5 percent of the requirement. Independent of any data center, staff project demand growth of about 1 percent a year. The City is building for that with the Ames Municipal Energy Center, three reciprocating engines due in 2031 at a total project value the City now puts at $192,673,833, up from the $84 million in the adopted 2027-2031 capital plan. On August 28, 2026 the Council held a noon special meeting by Zoom for one item: a $435,200 milestone payment to MISO for the interconnection agreement, priced at $8,000 per megawatt and due that day or the study slips a year.

Here is the comparison the record makes possible. Staff wrote that the new plant's 54 megawatts is "expected to be a replacement for the increasingly unreliable Unit 7 (33 MW), for a net gain of 21 MW to provide for some growth capacity within the service territory." The proposed data center's full buildout is 25 megawatts. Our arithmetic, from those two city figures: this one customer at full buildout would take more than the entire net capacity gain that a nearly $193 million generating plant is being built to add, and 25 megawatts is about 17 percent of the 148.8 megawatt combined coincident peak. Those are peak capacity comparisons rather than annual energy, and they are ours, not the City's. The Heart of Iowa DSA petition makes a similar point in different terms, calling 25 megawatts roughly a 15 percent increase in the city's consumption, and reported 4,331 signatures toward a goal of 6,400.

Staff's answer is that the customer would pay. The reports say the City would rely on the utility's Excess Facilities Charge so that "the data center alone pays for the improvements necessary to serve the site," that a new rate classification would be built with the utility's rate consultant, and that if MISO auction capacity costs more than the amounts embedded in adopted rates, "it would be necessary for the customer to pay for the difference." None of those instruments exists yet. Each would have to be negotiated. Our guides to who pays for data center power and data centers and your electric bill explain how such arrangements go wrong elsewhere.

The July 14, 2026 staff report is the most useful document in the file, because it is a public inventory of the City's own gaps. It summarized a City Attorney memo listing fourteen possible actions and flagged four that staff recommended "at a minimum," whatever happens to this proposal:

• Define the use. The Zoning Ordinance does not distinguish a data center from the existing data processing definition. Staff had already begun a text amendment, and the Planning and Zoning Commission reviewed part of it on June 3, 2026.
• Fix the electric tariff. Staff described "a discrepancy that exists between the adopted Electric Utility Tariff and the Utilities chapter of Municipal Code with respect to industrial customers," and said resolving it "would strengthen the utility's ability to require large power users to pay upfront for the installation of additional infrastructure necessary to serve the customer." Read that sentence twice. The mechanism the City is counting on to protect ratepayers is, by its own attorney's account, weaker than it should be.
• Add a water excess facilities charge. The report states the Utilities chapter "does not contain any provisions obligating a large water user to compensate the utility for the expansion of water production infrastructure necessary to serve it," naming treatment plant expansion, new wells, raw water pipeline and storage tanks.
• Add a sewer excess facilities charge. Same gap on the wastewater side.

The other ten were left to the Council: size, on-site generation and cooling limits; district restrictions and separation distances; site plan review that reaches utility impacts rather than only utility lines; a different approval route; a rewritten noise ordinance, which staff said "is designed more to address artificial noises produced from sources such as music, compared to addressing noises integral to a building's operation"; a moratorium; or a ban. Staff's own comment was that the approach giving "the greatest degree of control and accountability" is a rezoning with a master plan or overlay, which "would eliminate the ability of a data center to be developed by right."

On water, the proposal as described avoids the fight that made Iowa famous, because the cooling loop is closed and refrigerant based rather than evaporative. Ames draws its drinking water from 23 wells in the sand and gravel of ancient riverbeds of Ioway Creek and the South Skunk River, and federal records list its treatment plant as a groundwater system serving 55,177 people. What the file does not contain is any independent verification of the cooling design, or a single water condition written into an enforceable document, because no such document has been written.

The June 30, 2026 listening session filled the City Auditorium gymnasium with about 400 participants, split into thirteen breakout groups led by the Mayor, the six Council members and senior staff. The City has posted the poll results, photographs of every group's notes, and typed transcriptions. Staff distilled twelve categories of concern: environmental impacts, electricity demand and utility costs, water and wastewater, accountability and oversight, long term viability and future use of the buildings, public trust and transparency, the lack of data center regulations, artificial intelligence, public health, noise and vibration and low frequency humming, lack of public benefits, and economic impact and employment. Around the July 14 meeting the Ames Tribune and the Iowa State Daily published coverage under the headlines "Watch protestors march in opposition to proposed data center in Ames" and "City Council meeting opens with protest."

On July 28 the Council approved a motion, quoted in an August 11 memo from Assistant City Manager Pa Vang Goldbeck, "to form a study committee to look at environmental impacts not considered within the previous 12 items, including heat generation and localized temperature increases, and impacts on wildlife, habitats, and human health." A Council subcommittee of Gloria Betcher, Bronwyn Beatty-Hansen and ex officio member Trey Anderson wrote the plan, and the Council approved it on August 25.

The plan is short and specific. The committee is to "collect published data and reputable factual sources that represent the issues from multiple perspectives," identify reliable resources, deliver a report that summarizes them and links to them "without arguing in favor of or against particular action," and present it at a Council meeting. Members must be "experts in fields related to these issues or individuals with expertise derived from education or professional practice in related fields," and the plan adds that "a simple interest in the topic shall not be considered expertise." City staff are excluded from the committee and its deliberations, the committee runs itself, its meetings "shall abide by the Open Meetings Law," and the plan does not fix the number of seats.

The timeline: applications opened August 26 and close September 9; the Council subcommittee chooses members by September 13; the Council approves them at a special meeting on September 15; the committee meets by September 30 to pick a chair and set a research strategy; a first round of research is due by December 31; an optional second round by January 31, 2027; the report to Council by February 28, 2027; and presentation at a Council meeting on March 13.

Three things are genuinely open, and a resident who wants to be useful should go after them.

The term of the pause. On July 28, 2026 the Council took up a Council Action Form titled "Temporary Delay in Allowing Data Center Developments." Staff had drafted a resolution and recommended six months, "a temporary pause in data center developments through January 2027," with an alternative to extend it by one to two months. The Iowa State Daily published a story two days later under the headline "City Council delays data center decision 9 months." The City's own data center page does not post that resolution and does not use the words delay, pause or moratorium anywhere, and the Recently Adopted Ordinances list runs through Ordinance 4602 with no data center ordinance on it. So a delay is reported, its nine month length rests on one outlet's headline, and the resolution itself is not published where the City publishes everything else about this project. Ask for it by name.

The lease. The Council has not authorized staff to negotiate one. Staff laid out four options on July 14: pursue the regulatory fixes, authorize lease negotiations, decline the request, or ask for more information. Staff also warned that declining would not end the matter, because "unless the City Council took further steps to modify the City's existing ordinances, it is possible that Lightedge could pursue an alternative site within Ames."

The approval route. Everything turns on whether data centers stay a by right industrial use reviewed by staff, or become a Council decision, a board of adjustment decision, or a contract rezoning. Staff has recommended the last as the strongest. The Council has not chosen. Until it does, the meaningful decision in Ames gets made at site plan review, the quietest room in any city hall.

Ames is the clearest example in the country right now of a data center decision that has not been made. Compare it with the Cass County, Nebraska moratorium, where residents stopped a project at the permit counter, or with the Salix annexation fight elsewhere in Iowa, where 900 acres changed hands before anyone knew what would be built. In Ames the sequence ran the other way. The proposal reached a public council meeting first, and the record has been public since June. If you live there, the concrete steps are these:

• Apply to the study committee by September 9, 2026, if you have relevant education or professional practice. The plan is explicit that general interest does not qualify, so lead with your credentials.
• Get your comment into the record at a Council meeting. The Council meets in the Council Chambers at City Hall, 515 Clark Avenue, and its published notices set hearings at 6:00 p.m. on September 22 and October 13, 2026, with a special meeting on September 15 to approve committee members. If a challenge to a later decision ever becomes necessary, standing and preservation questions turn on whether you were heard at the administrative level first.
• Request four documents by name. The July 28, 2026 resolution on temporary delay of data center developments and its exact expiration date; the minutes of the June 16, June 23, June 30, July 14, July 28 and August 25, 2026 Council meetings; any draft lease, excess facilities charge agreement or rate classification study for this customer; and any FAA correspondence about releasing the airport parcel from its federal obligations. The City Clerk's office handles open records requests, and the by year minutes archive sits in a portal that requires JavaScript to browse, so a written request is the reliable route.
• Watch the ordinance calendar, not the project. Staff's schedule put first readings for the data center definition, size limits, allowed districts and industrial use report requirements in August, water and sewer excess facilities language in December, and the electric tariff fix in January. Those votes decide what any data center in Ames must meet, this one or the next one.
• Document your baseline now. Sound readings, dated photographs, and well tests if you are on a private well outside the city system are what make a later claim provable. Our evidence guide has the checklist, and our guide to fighting a proposed data center walks through the approval process.

The Iowa state page covers the wider picture, including a moratorium wave that has reached more than 25 Iowa counties and at least six cities. If a facility near you has already been built and is affecting your home, our free case review connects you with an independent attorney in our network handling data center matters in Iowa, at no cost and with no obligation. Ames is not that situation yet. It is the situation before it, which is the only one in which a resident still gets a say.
