U.S. Sen. Bernie Moreno (R-Ohio) has called on private equity company Carlyle Group (Carlyle) to return a $4.5 million state subsidy approved for a data center expansion in Northeast Ohio. The decision has sparked debate over whether data centers should receive taxpayer incentives due to their large energy consumption and low permanent jobs. Moreno called on Carlyle to sign onto President Trump's "Ratepayer Protection Pledge" to prevent data centers from shifting electricity costs onto consumers. In return, Ark Data Centers committed to creating 10 full-time jobs and maintaining operations locally for at least 13 years. The company has not responded to a request for comment.
