Two firms, Houston-based Cloverleaf Infrastructure and Atlanta-based Beltline Energy, both proposed AI campuses around the Mathewson Substation in Piedmont, Oklahoma, after Southwest Power Pool finished a $72 million, 345-kV line into it.
In Piedmont, Oklahoma, Cloverleaf pitched a 500 MW (expandable to 1.5 GW) facility next to the Matthewson substation with closed-loop cooling and committed to funding a new water tower, water mains, and road upgrades through the city rather than drilling wells.
