Over the summer, I wrote a blog post discussing where Ohio’s data centers are headed. As of then, I calculated that there are currently about 143 planned or proposed data centers in Ohio. In some of these cases, there are more than 10 individual data center facilities planned for one campus. For example, in Shalersville, Bitdeer, a cryptocurrency mining and artificial intelligence infrastructure company, has 14 data center facilities planned in 2029 and 2031 for just one campus.
If all of these planned data centers are built by 2034, Ohio will more than triple its data center energy capacity. Increasing energy draw has implications on emissions, utility bills, and more. Many Ohio residents and municipalities share these concerns. According to a poll from Bowling Green State University, 78% of Ohio residents support data center moratoriums until more information can be gathered about their effects, 75% are opposed to construction in their local communities, and 63% are opposed to construction elsewhere in Ohio.
A great new story from the Ohio Capital Journal finds that at least 138 Ohio municipalities and townships have active moratoriums on data centers as of September 17, 23 communities have effectively banned data centers, with at least 23 more considering similar proposals. Today, I want to explore what would happen to Ohio’s planned data center projects under these moratoriums and bans.
How will moratoriums and bans affect Ohio data centers?
Of the 143 planned or proposed data centers in Ohio, 22 of them would be impacted by current moratoriums, one data center would be impacted by a proposed moratorium, and one data center would be impacted by a proposed ban. That leaves 119 data centers in Ohio that would currently be unaffected by moratoriums or bans across the state.
Part of the reason why relatively few proposed data centers in Ohio remain unaffected by moratoriums or bans is that the proposed data centers across Ohio are mostly concentrated in certain municipalities. For example, New Albany, Ohio has 42 proposed data center facilities across 15 campuses. And Jeffersonville, Ohio has 23 proposed data center facilities on the same Amazon Web Services campus.
The map below shows the planned and proposed data centers in Ohio and which facilities could be impacted by current and proposed moratoriums and bans.
Many of these moratoriums are set to end soon. The moratoriums in Niles and Shalersville are set to expire in November 2026, the moratoriums in Lordstown, Springfield, and Sunbury are set to expire in January 2027, and the moratorium in Urbana is set to expire in March 2027. Other moratoriums are expected to expire later though, with Commercial Point’s moratorium set to expire in November 2027 and Lima’s moratorium set to expire in March 2028.
The moratorium in Commercial Point is currently being challenged in court by an Amazon subsidiary. In May 2024, the Commercial Point Village Council moved to rezone large parcels of land to a district exclusively designed for data center development. The council originally voted 4-1 to bypass the standard public referendum period and pass the zoning ordinance as an emergency measure. By statute, however, the Commercial Point Village Council has a 6 member council, which was down to 5 members due to a recent resignation. 14 days prior to the vote, Commercial Point’s mayor indicated that waiving standard zoning ordinance rules requires 5 votes. Now, the Amazon Web Services data center’s existence comes down to whether passing the zoning ordinance for it was legal to begin with.
In the figure below, we show how annual carbon emissions would change if all current moratoriums and bans are maintained.
If current moratoriums and bans are maintained, we project that the annual electricity generation from data centers in Ohio will decrease by about 28 million megawatt-hours per year by 2028. For every 100 million megawatt-hours of electricity generation per year, we could power around 9.2 million homes. For reference, there are around 4.9 million homes in Ohio, meaning that by 2028, the electricity generation from Ohio data centers could power all of the homes in Ohio about 4 to 5 times.
What does the future hold for data centers in Ohio?
As opposition to data center development in Ohio grows, it’s possible that more moratoriums and bans will emerge, which could impact Ohio’s data center landscape even more. An interesting pattern I noticed is that many moratoriums and bans are happening in municipalities that border planned data center sites, but not within the municipalities data centers are planned for themselves. One possibility is that community opposition to data centers grows in areas that have planned data centers nearby, but it’s more challenging to pass moratoriums and bans in the municipalities where planned data centers are located due to fear of legal trouble or tax exemptions that have already been agreed upon.
Some data centers have begun implementing policies that could help ease community concerns. All of the data centers that are currently planned for Ohio have announced plans to implement closed-loop cooling methods. Closed-loop cooling is great for reducing water use, but it also uses more electricity than open-loop cooling.
Additionally, about 19% of proposed data center projects in Ohio are planned to use behind-the-meter electricity generation. This means that data center facilities would not be drawing electricity from Ohio’s statewide grid, which would lessen the impact of higher electricity prices on ratepayers. It also means that data centers might be using cleaner energy sources than the Ohio grid, which would reduce emissions.
As data centers grow both more popular among developers and more contentious around community members, it’s important to find policies that address community concerns around data centers. Scioto Analysis plans to release a cost-benefit analysis about different data center policies at the beginning of October where we analyze the impacts of different policies in Ohio such as a ban or requiring energy to be generated behind-the-meter.
