New Albany

hosts Google, Meta, Microsoft and AWS campuses on one suburban plain, the Midwest's data center capital

Water stress

Low: Great Lakes-adjacent supply is ample; the contested resources here are grid capacity and farmland, with water third.

The local story

Central Ohio quietly assembled the Midwest's largest cluster: Google, Meta, Microsoft and AWS all operate or are building in the New Albany–Columbus corridor, drawn by water security, AEP's transmission and aggressive municipal recruitment.

Columbus's water position is the recruiting pitch: the region markets itself explicitly as the low-water-risk alternative to Phoenix and Salt Lake. The honest caveat is indirect: Ohio's grid still burns significant gas and coal, so Mid-scenario water per kWh runs above the national average even when on-site cooling is efficient.

Watch the AEP interconnection queue: the utility's data-center tariff fight (who pays for new transmission) became the national template, and its outcome shapes how much more capacity (and cooling load) lands here.
