Fluidstack’s Data Center Expansion
Coverage from MyRGV.com, KRGV, and others

Fluidstack’s data-center expansion includes a planned campus of more than 1,100 acres near Harlingen and Rio Hondo in Cameron County, Texas, as well as a site associated with the company in Glendale, Arizona.
The Texas project’s first phase has been described as a multibillion-dollar buildout, with closed-loop cooling and proposed arrangements for power, water, stormwater drainage, and local taxes. Its development has also involved county permitting and discussions with Harlingen officials about drainage infrastructure and community impacts. Details available about the Glendale site are more limited.
