The strategic read
Adds one of the largest explicitly power-first AI data-center projects in the U.S. buildout. The scarce asset is the full electrical stack: federal land reuse, 10 GW of new generation, 765 kV transmission, four substations, gas-pipeline support, and ratepayer-protection structure around a planned AI campus.
