What it would mean nearby

The cooling design has not been reported. If it uses evaporative cooling, a 73 MW facility would draw roughly 231,000 to 833,000 gallons of water a day, about what 2,700 households use.

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.
