## Gallman Facility Anchor of $1.5 Billion U.S. Manufacturing Expansion

On September 15, 2026, Hitachi Energy unveiled a landmark $528 million investment to construct a state-of-the-art power transformer manufacturing plant in Gallman, Mississippi. The new facility serves as the centerpiece of Hitachi Energy’s broader $1.5 billion multi-year U.S. manufacturing expansion program, which also includes capacity upgrades in Pennsylvania, Virginia, and Tennessee.

The Gallman facility will be more than double the physical footprint of the company’s existing Crystal Springs facility and is slated to create over 700 high-skilled manufacturing and engineering jobs upon operational launch in 2029.

## Targeting Mid-Range Transformers (10–160 MVA) for Data Centers and Substation Upgrades

The facility will specialize in mid-range liquid-immersed power transformers from 10 MVA up to 160 MVA with voltage ratings up to 230 kV. This equipment class is in acute demand from hyperscale cloud operators and semiconductor manufacturing foundries requiring dedicated dedicated on-site substations.

With transformer delivery backlogs extending up to 2 to 4 years industry-wide, the Gallman manufacturing lines incorporate automated robotic core-stacking, vapor-phase drying autoclaves, and digitized acoustic test bays to dramatically shorten lead times while achieving strict Tier-2 efficiency compliance.
