Ohio governor Mike DeWine (R) temporarily halted new data center tax exemptions after local media reports showed the incentives cost the state over $1bn in revenue last year.
DeWine directed the tax credit authority to stop accepting new requests for exemptions while the legislature's Joint Data Center Committee examines the impact of data centers on local communities. The pause only applies to tax exemption requests and is not a ban on data center development, he said this week.
The move is a reversal of sorts for the Republican governor who has been a supporter of data center investment and last year vetoed a legislative attempt to end the sales and use tax exemption, enacted in 2013.
"What was estimated at $300 million in lost revenue is now $1.6 billion," state representative David Thomas (R) said on social media this week. "The legislature was not told of this cost until seeing it in the newspaper. I am strongly encouraging removing this sales tax exemption fully in Ohio Law."
DeWine emphasized that data centers that have received tax exemptions reported more than $27bn in capital investment in Ohio last year.
The tax credit pause comes as state and local governments in other high-growth markets take a more critical look at the rapid buildout of data centers. In neighboring Pennsylvania, governor Josh Shapiro (D) recently introduced Governor's Responsible Infrastructure Development (GRID) standards that tie tax incentives and fast-track permitting to stricter requirements on energy sourcing, grid costs and environmental performance.
Opposition is also gaining strength in Texas, where counties and cities have moved to block or slow projects through moratoriums, zoning denials and new restrictions tied to water use and land use. The pushback, spanning both Republican- and Democratic-leaning areas, comes as regulators warn that data centers could drive electricity demand to more than quadruple in coming years.
Ohio has the fifth-largest number of data centers in the country, with more than 200 facilities, according to the Office of the Ohio Consumers' Counsel. The rapid expansion has coincided with rising power costs, with Ohio households facing increases from 10-35pc last summer as regional grid operator, PJM Interconnection, paid dramatically more to secure future reserve capacity.
