Gallman Transformer Manufacturing Facility

Hitachi Energy — the power-grid subsidiary of Hitachi, Ltd. — announced on September 15, 2026 a $528 million investment to build a new transformer manufacturing facility on a 45-acre site at the Copiah County Industrial Park in Gallman, Mississippi, about 6.5 miles from its existing Crystal Springs facility. The Mississippi Development Authority figure covers the new factory, manufacturing equipment, and infrastructure improvements, and the project is expected to create 654 net-new permanent jobs. AFT records MDA's firm 654 net-new figure (not Hitachi's less specific "over 700 jobs" wording) and deliberately excludes the 475 people already employed at Crystal Springs. Transformer production will transition to Gallman when the new plant is complete, with production expected in 2029; the Crystal Springs building will remain in use for warehousing, training, or other operational needs and is not closing. AFT counts only the $528 million assigned to the Gallman site and excludes the broader ~$1.5 billion Hitachi U.S. manufacturing expansion program as well as its investments in Virginia, Tennessee, and Pennsylvania. Construction is expected later in 2026 but has not been confirmed as started, so the project is classified as Announced.

Why this project qualifies

With $528 million in facility-specific investment and 654 permanent operating jobs announced, this project clears both of AFT's qualifying thresholds ($100 million in facility-specific investment OR 100 permanent operating jobs). This project also meets AFT's primary-source verification and physical U.S. manufacturing-footprint requirements.

Why it matters

The electrical equipment & grid context.

Electrical Equipment & Grid tracks major U.S. factories producing the equipment required to generate, transmit, control, and distribute electricity — including transformers, switchgear, generators, turbines, cables, and other grid components. It distinguishes equipment manufacturing from power generation, utility construction, energy production, and service-only projects.
