Every Data Center in Ohio: Operating, Under Construction, and Proposed

This page counts every data center campus Ohio has, is building, has been offered, or has turned away, as of October 15, 2026. The tally: nine operating hyperscale and wholesale campuses, thirteen under construction, fifteen live proposals, ten withdrawn, rejected, or paused, and twenty-two colocation operators across thirty operator-metro rows. The largest project in the state is also the largest in the country on paper: the PORTS-Pike Technology Campus at Piketon, where SB Energy plans 8 GW of IT load for OpenAI on the site of a Cold War uranium enrichment plant, fed by 10 GW of new gas generation. Behind it stand Meta’s 1 GW Prometheus cluster in New Albany, Cologix’s $7 billion Johnstown campus, and Amazon’s $23 billion statewide expansion. AEP Ohio told regulators in February 2026 that it had 17,861 MW of data center load under signed contract, against a system peak that has never exceeded about 10,500 MW.

The skyline above is downtown Columbus, where the Public Utilities Commission of Ohio approved the first data-center-specific tariff in the country in July 2025 and where the General Assembly spent 2026 arguing about a sales tax exemption that cost the state $1.6 billion last year. Ohio’s tariff is the model other states are copying, and we compared it with Texas and Virginia in California’s data center laws. The bill impact of PJM’s capacity auctions, which Ohio feels as sharply as any state, is covered in AI and your electric bill and PJM’s backstop auction. The Piketon campus appears in The summer of the gigawatt campus, and Oklo’s plan to build 1.2 GW of small reactors next door is in The nuclear comeback.

At a glance

Status	Projects	Disclosed capacity
Operating hyperscale and wholesale	9	About 1.3 GW, mostly tracker estimates
Under construction	13	About 2.3 GW where disclosed
Proposed or pending	15	About 10.1 GW where disclosed
Withdrawn, rejected, or paused	10	About 0.4 GW
Colocation and enterprise	22 operators, 30 metro rows	About 94 MW disclosed critical load

Capacity is the sum of megawatts a developer, county filing, utility, or regulator has put on the record for that bucket. Ohio’s hyperscalers disclose less than most. Amazon, Google, and Meta publish acreage and dollar pledges rather than megawatts for their operating campuses, so the operating figure leans on tracker estimates and should be read as an order of magnitude. AEP Ohio’s own numbers are the better gauge of scale: its September 2026 submission to PJM projects 13,900 MW of cumulative large-load additions by 2030 and 17,116 MW at full buildout, counting only customers with a signed agreement.

Operating hyperscale campuses

Ohio’s data center industry began in New Albany, a planned suburb on the Franklin and Licking county line northeast of Columbus, where Amazon opened its first Ohio building in 2016 on farmland that the city had annexed into a 12,000-acre business park. The city counts 40 data centers opened there since 2010 and 28 more planned or under construction. Google, Meta, Microsoft, QTS, Edged, STACK, Vantage, EdgeConneX, and Cologix have all followed Amazon into the same corn and soybean fields along Beech Road and Green Chapel Road, and the campuses now run east past Johnstown into rural Licking County.

The Cologix Johnstown campus is the one to watch in this bucket. Cologix has run the Columbus carrier hotel on Scherers Court for a decade, and in June 2026 it announced a $1.1 billion first phase of an 800 MW AI campus split between Johnstown and Orange Township in Delaware County. The Tax Credit Authority approved its 10-year sales tax exemption, worth an estimated $42.3 million, on June 1, 2026, the last such award before Governor DeWine’s pause took effect.

Proposed and pending

The newest proposals have moved well beyond central Ohio. The biggest sit in the farm counties of the south and northwest: Pike County, where the federal government’s former Portsmouth Gaseous Diffusion Plant is being offered as a 10 GW campus; Adams County, where Amazon is evaluating 1,300 MW on about 1,000 acres near Manchester; Van Wert County, where QTS has taken over a 902-acre, $10 billion plan; and Allen and Scioto counties, where Google has announced campuses at Lima and Franklin Furnace. Each of these counties is mostly farmland, and each has drawn the same question from residents that the farm towns around Columbus asked two years earlier.

Oklo’s 1.2 GW Aurora campus on 206 acres at the same Piketon site is a power plant, not a data center, so it is not a row, but it belongs in the picture. Meta signed a prepayment agreement in January 2026 to fund the first phase’s nuclear fuel, with site work in 2026, first power as early as 2030, and the full 1.2 GW by about 2034. The PORTS-Pike campus itself was announced on March 23, 2026, by the Department of Energy, AEP, and a SoftBank-led consortium, with 9.2 GW of gas generation funded by $33.3 billion in Japanese capital and $4.2 billion committed by SB Energy for AEP’s 765 kV transmission work. State Senator Shane Wilkin called it the single most significant economic development in southern Ohio’s modern history.

Withdrawn, rejected, or paused

“Pickaway County has a lot of farmland, and I think all of it is at risk.”

Sue Carter Moore, a resident of the Ashville area, said that to WSYX in December 2025, the week the village council passed an emergency moratorium on rezoning for EdgeConneX’s 680-acre campus. Ashville’s council denied the annexation in February 2026, and the project is one of ten in this bucket, a list that did not exist in Ohio eighteen months ago. Microsoft’s three Licking County sites remain the largest pause. Microsoft stopped work in April 2025, and its June 2026 economic impact document says only that three Licking County data centers will be operational by the end of 2029. An advocacy site claims construction resumed in February 2026, but no news outlet has confirmed that, so the rows stay here.

Pataskala is the clearest case of a market turning. Aligned’s 200 MW Mink Street site plan went to the planning commission on June 3, 2026, and lost 5-2, and the city council rejected it on August 25. Brandon Galik, the council president, told NBC4 there were big concerns with the power alone. Residents gathered more than 500 signatures afterward, and a ban on data centers over 25 MW goes to Pataskala voters on November 3, 2026.

Colocation and enterprise facilities

Ohio’s retail colocation market is three metros and a long tail. Columbus has the carrier hotel on Scherers Court in Worthington, which Cologix has grown into four buildings with a fifth due in late 2026, plus Expedient’s three sites and a cluster of smaller operators in Dublin and Lewis Center. Cleveland’s market centers on the Sterling Building at 1255 Euclid Avenue, where DataBank and BlueBridge are separate tenants on separate floors, and on H5’s Cleveland Technology Center on Rockwell Avenue, the city’s carrier hotel. The photo below looks across Lake Erie toward downtown Cleveland from the west side. Cincinnati’s largest provider is CyrusOne, which began life as Cincinnati Bell’s data center arm and still runs the old Seventh Street switch complex downtown.

Every address above was confirmed on the operator’s own website or its own PeeringDB record. Directory sites list more: a T5 building on West 150th Street in Cleveland that was sold to StratCap in 2022, CyrusOne sites in Hamilton and Mason that have dropped off CyrusOne’s own location list, a former Involta site in Youngstown that ark no longer lists, and Bitdeer’s crypto mining halls in Massillon. None of those could be verified as an operating colocation facility and none appears in the table.

Power, policy, and moratoriums

Ohio wrote the rulebook that other states are now copying. AEP Ohio filed for a data center tariff in May 2024 after reporting more than 30,000 MW of connection requests, and the PUCO approved it on July 9, 2025, over the objections of Microsoft, Amazon, Google, and Meta, who had proposed a 70 percent minimum. The tariff applies to new loads above 25 MW and requires customers to pay for 85 percent of their subscribed capacity every month whether they use it or not, for up to 12 years with a four-year ramp, plus an exit fee equal to three years of minimum payments and collateral of half the minimum charges. The commission’s stated goal was to make developers stop reserving capacity they would never use, and by that measure it worked. After the tariff took effect, developers had 45 days to submit load studies and filed 13,022 MW across 36 sites, less than half the earlier queue. By February 2026, AEP Ohio said 5,642 MW had signed service agreements under the new tariff, on top of 12,219 MW signed before it, for a total of 17,861 MW. PUCO Chair Jenifer French told the House Select Committee on Data Centers in May 2026 that 5,642 MW is still a lot of load but a lot less than 30,000, and that the tariff had saved other ratepayers millions in unnecessary infrastructure. The Ohio Manufacturers’ Association appealed the order to the Ohio Supreme Court in November 2025, calling it discriminatory, and the case was still pending as of this writing. PUCO has since directed FirstEnergy’s three Ohio utilities to propose their own data center tariff, and AES Ohio’s pending rate case would create a separate data center class in Dayton from January 2027.

The second fight is over the sales tax. Ohio exempts data center equipment from sales and use tax through a program the Department of Taxation now says cost $1.57 billion in 2025, eleven times the state’s own earlier estimate. The General Assembly repealed the exemption for new projects in the 2025 budget, Governor DeWine vetoed the repeal on June 30, 2025, and House Speaker Matt Huffman spent the spring of 2026 trying and failing to find the votes for an override after Google, Microsoft, Amazon, Meta, the Ohio Chamber, and the building trades unions all wrote asking him not to. On May 27, 2026, DeWine paused all new exemption awards himself while the new Select Committee on Data Centers studies the program. Eighteen companies hold exemptions worth at least $2.3 billion in committed value, with Google, Meta, and Amazon affiliates at about $600 million each on terms that run as late as 2058. Two broader bills are stalled in the General Assembly. HB 646 passed the House 97-0 in March 2026 as a study commission and came back from the Senate as a fifty-page rewrite that would halve the exemption, cap property tax abatements, require any data center over 250 MW to bring its own power, and order PUCO to create a statewide data center rate class. Neither chamber had the votes before the summer recess. HB 706 would write the AEP tariff into state law for every utility. Maureen Willis, the Ohio Consumers’ Counsel, told the select committee in May that residential consumers should not provide free reliability insurance for extraordinary private development.

Power for the new campuses is increasingly coming from behind the meter, which House Bill 15 made easier when it took effect in August 2025. The Ohio Power Siting Board has approved five gas plants in New Albany alone: Williams’ two 200 MW Socrates plants for Meta, a 250 MW third plant with a 116 MW battery, and EdgeConneX’s 120 MW and 216 MW PowerConneX plants. Pending before the board are an 800 MW EdgeConneX plant in Pickaway County and a 1,300 MW gas plant with 1,000 MW of batteries at Millersport for Vantage. French said that in 2025 the board authorized or received applications for more than 2,000 MW of behind-the-meter dispatchable generation. Meta also signed 20-year contracts with Vistra in January 2026 for 2,609 MW from the Davis-Besse and Perry nuclear plants, including 433 MW of uprates, and in November 2025 asked PUCO to let it draw up to 250 MW from the Green Chapel substation that AEP built for Intel’s delayed fab. The bills for all of this run through PJM. Its 2027/28 capacity auction cleared at the $333.44 per megawatt-day cap, with a 5,250 MW load increase that PJM said was almost entirely driven by data centers, and Ohio’s industrial electricity prices were up 26 percent year over year in December 2025.

The local response has been the fastest in the country. The Ohio Capital Journal counted 138 municipalities and townships with active data center moratoriums as of September 17, 2026, up from about 18 in February, and 23 communities that had effectively banned the industry. Jerome Township in Union County went first in September 2025. Lordstown, Ashville, Sunbury, Jackson Township, Pierce Township, Ravenna Township, Muhlenberg Township, and two townships in Adams County followed, and Cleveland rejected a hyperscale permit in Slavic Village in May 2026. A Bowling Green State University poll in September 2026 found 78 percent of Ohioans supported moratoriums and 75 percent opposed a data center in their own community. Data centers are on the November 3, 2026, ballot in Pataskala and Grove City among other communities, and both candidates in the state’s Senate race ran on who should pay for the grid. Governor DeWine, who has defended the industry, put it plainly in June: they have to pay their own way.

How this list is maintained

Rows come from operator announcements, county and township filings, Ohio Power Siting Board and PUCO dockets, the PeeringDB facility registry, and local reporting; every row traces to at least one source in the list above, and every colocation address was checked against the operator’s own site before publication. A hyperscale or wholesale campus is one row per campus, while colocation is one row per operator per metro because Columbus is large enough that per-building rows would run to pages. Tracker estimates are marked as such. Corrections and additions are welcome through the About page, and every refresh is marked with an updated date at the top of the page.
