Hitachi Energy Plans $528 Million Transformer Factory in Mississippi

Hitachi Energy plans to build a $528 million transformer manufacturing facility in Gallman, Mississippi, as the largest single U.S. investment in the company’s history. Announced September 15, 2026, the factory is expected to create more than 700 jobs and more than double the company’s local transformer-production capacity.

The site will be about 6.5 miles from Hitachi Energy’s existing Crystal Springs plant and more than twice its size. Construction is expected to begin in late 2026, with production scheduled to start in 2029. Hitachi Energy says transformer manufacturing will transition from Crystal Springs to Gallman after the new plant is complete.

A factory tied directly to grid demand

Large power transformers are long-lead assets used in generation interconnections, transmission substations and major grid reinforcements. Manufacturing capacity has become a delivery constraint as utilities replace aging equipment and add capacity for new load.

The Mississippi project anchors an approximately $1.5 billion U.S. manufacturing expansion that also includes investments in Pennsylvania, Virginia and Tennessee. Hitachi Energy presents the program as a response to domestic demand for transformers and other grid equipment, not as a stand-alone real-estate development.

What it means

Analysis: The announcement adds manufacturing capacity at a point where utilities are under pressure to shorten equipment lead times. A new plant can expand output, but the impact will depend on workforce ramp-up, supplier capacity, factory qualification and the production schedule for different transformer classes.

The transition from the existing Crystal Springs operation is also an execution issue. Maintaining deliveries while moving or expanding processes will require careful phasing. Customers will watch whether capacity begins to improve before full 2029 production or only after the new facility is commissioned.

For Mississippi, the project combines a major industrial build with a specialized labor requirement. Training, housing, transportation and utility service around Gallman will influence how quickly the announced jobs and production targets can be realized.
