Amazon and AEP Ohio plan to install 228 Bloom Energy fuel cells on about six acres of Amazon's existing Cosgray Road data center campus in Hilliard, a 73 megawatt array that would be the largest fuel cell installation in North America. The Ohio Power Siting Board approved the project under the state's behind the meter power law despite organized neighborhood opposition and a lawsuit filed by the City of Hilliard.

Power bills in Franklin County
Most of the county is served by AEP Ohio.
AEP Ohio distribution rate case (docket 25-0392-EL-AIR) takes about $1.22 a month off a typical bill, decided April 1, 2026. This is a minimum bill requirement for very large new customers, not a rate change for homes, but it exists specifically to keep data center grid costs off residential bills.
AEP Ohio asked to raise electric distribution rates, which as filed would have added about 3.95 dollars a month, or 2.14 percent, for a typical household using 1000 kWh. PUCO instead approved a settlement on April 1, 2026 that lowers the typical residential bill by about 1.22 dollars a month and sets AEP Ohio's allowed return on equity at 9.84 percent. The settlement also creates a minimum monthly charge specifically for new data center customers, building on PUCO's earlier data center tariff order.
