Ohio Voted. The Pipeline Felt It.

At least 14 Ohio communities banned or capped data centers on Election Day. Grove City now requires a public vote above 50 acres, 20 MW or 500,000 gallons a day. Local politics is a site criterion.

Ohio used to be sold as PJM power, Midwest fiber and friendlier land than Northern Virginia. On November 3, voters in Ohio communities passed at least 14 bans or limits on data centers. Some banned them outright. Others capped sites above 25 MW. Grove City will require a public vote for any project over 50 acres, 20 MW or 500,000 gallons of water a day (DCD; The Guardian).

That is not a zoning skirmish. That is a market reprice.

Local ballots beat regional narratives

Data centers were on the ballot in at least 40 jurisdictions across 10 states. Voters approved nearly every moratorium or restriction put in front of them. Ohio was the densest cluster. Maine towns including Peru, Wells and Eliot passed 180-day moratoria. Alhambra, California banned data centers. Kansas votes in Emporia and Ottawa still face court questions. The small exception was Harwood, North Dakota, which voted down extra industrial review (DCD).

DCD, citing exit polls, reported that 56% of voters called AI data centers a crucial or major factor in their Congressional vote. Governors amplify the local map. Ohio’s Amy Acton and peers in Georgia and Texas campaigned on pauses. BMI estimates about 53% of hyperscale pipeline growth from 2028 onward sits in newly flipped governor states including Ohio. Cleanview put 159 GW of planned U.S. capacity — 41% of the pipeline — in states where new governors backed a pause (DCD; The Guardian).

Columbus and the broader Ohio market already ran extremely tight on available power. A public-vote trigger at 20 MW turns every mid-size wholesale deal into a campaign. Water thresholds pull cooling design into the political process. Acreage caps punish campus strategies that need land for phased halls and on-site generation.

PJM’s registry is not a public queue

On October 9, FERC accepted PJM’s Large Load definition and registry, effective October 12, and rejected the rest of the filing. The registry is not a public per-request queue. NYISO remains the only U.S. ISO with a public request-level large-load list (FERC order via PJM).

So even before Election Day, Ohio developers were inferring wait times from utility talks and IRPs, not from a transparent stack. After Election Day, a cleared PJM study does not help if the township bans the use. Power permission and land permission are separate critical paths. CBRE’s H1 2026 work already ranked community acceptance alongside power procurement as a first-order site constraint. Ohio just provided the case study (CBRE).

How site selection changes tomorrow morning

Underwrite the county commission the way you underwrite the substation. Budget for referendum risk on anything above local thresholds. Prefer jurisdictions that already hosted campuses without a backlash, or that have explicit ordinance paths rather than ad hoc ballot fights. Expect NDAs to become liabilities in places that just voted against opacity. OpenAI’s post-election pledge to drop most NDAs with public officials — limited to sites it owns and operates — is a recognition of the same pressure.

For existing Ohio pipeline, sort projects into three buckets: entitled and under construction; entitled but not started; and pre-entitlement. Only the first bucket is inventory. The second is optionality with political decay. The third is a press release.

Columbus pricing will tell the truth

If local bans bite, expect Columbus and nearby Ohio nodes to behave like other politically capped markets: higher asking rates on the remaining entitled supply, longer preleasing into future years, and more capital chasing sites that already cleared hearings. Water and acreage triggers pull campus design into politics — a 20 MW public-vote threshold is low enough to catch a large share of modern wholesale deals.

Developers will test neighboring townships and rural counties next. Some will welcome the tax base. Some will copy Grove City. The winners will be the teams that run political diligence before the LOI, budget for referendum risk and prefer ordinance paths over ad hoc ballot fights. A cleared PJM study with a hostile township board is not a site. It is a lawsuit calendar.

BMI’s midterm read — that roughly half of hyperscale growth from 2028 on sits in newly flipped governor states including Ohio — means local Ohio bans are not a one-county story. They are a discount rate on an entire regional pipeline until ordinances stabilize.

Why it matters for builders, buyers and investors

Ohio’s election night did not delete PJM megawatts. It deleted the assumption that a power position equals a buildable site. Builders need political diligence before LOI. Buyers should treat local vote triggers as deal-break conditions. Investors with Midwest developer books should haircut pre-entitlement pipeline harder than their 2025 models did.
