Who wanted it

Who asked for it: Meta — self-build
Who approved it: City of New Albany / Licking County JEDZ agreements; AEP Ohio data center tariff approved by PUCO in 2025 after a contested case
What it serves: Meta's first multi-gigawatt AI training cluster
IT capacity: 300 MW running of 1,000 MW announced

Meta trucked in on-site gas generation to beat the interconnection queue. The PUCO tariff fight here set the national precedent that large loads must post collateral for the capacity they reserve.

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.
