Who wanted it

Who asked for it

All four major hyperscalers, each with its own campus

Who approved it

New Albany's pre-zoned business park; AEP Ohio's contested data center tariff, approved by PUCO in 2025, requires large loads to pay for 85% of subscribed capacity whether or not they use it

What it serves

AWS us-east-2, Google and Microsoft cloud regions, Meta app serving

IT capacity

900 MW running of 2,500 MW announced

The AEP Ohio case is the most-cited regulatory precedent in the US: it established that data centers must post minimum-demand commitments so that other ratepayers aren't left holding the bill for capacity that never materialises.

Where it is

40.0500°, -82.9500°

Water and air figures are modelled from disclosed capacity, not measured — site-level error is roughly ±40%. Diesel backup generators are not counted, so on-site figures are floors. Full method.
