“For most fabricators, the grid boom is a national headline. For us, it's a local one.”
A $25 billion wave of hyperscale datacenter investment — anchored by Amazon — has landed in central Mississippi, paired with Entergy's largest grid upgrade to date. The build-out reshaping the national power grid is happening in the same counties FabTek has operated in for years.
When the demand is in the region and the fabrication is in the region, the math gets simple: shorter freight, tighter coordination, and a partner already investing in capacity ahead of the curve in the same state the build is happening.
