Hitachi Energy commits $528 million to a new transformer factory in Gallman, Mississippi.

Hitachi Energy, a wholly owned subsidiary of Hitachi, Ltd., announced on 15 September 2026 plans for a new $528 million transformer manufacturing facility in Gallman, Mississippi. The company’s PR Newswire release frames the plant as Hitachi Energy’s largest single investment in the United States to date and as the cornerstone of an around $1.5 billion U.S. manufacturing expansion programme that also includes major projects in Pennsylvania, Virginia and Tennessee. Reuters’ same-day brief confirmed the $528 million Mississippi factory figure and the “single-biggest” U.S. manufacturing-expansion characterisation.

The mechanism is industrial and dated. The new Gallman factory will sit about 6.5 miles (ten kilometres) from Hitachi Energy’s existing Crystal Springs facility, at more than twice the size of the current plant, and is intended to more than double capacity, according to the PR Newswire text. Construction is expected to begin late this year, with transformer production scheduled to start in 2029. Once the new factory is complete, transformer production will transition from Crystal Springs to Gallman; the existing Crystal Springs building is to continue in warehousing, training or other operational uses.

Mississippi-side detail from the Meridian Star / Magnolia Tribune write-up of Governor Tate Reeves’s announcement: the project includes purchase of a 45-acre site at the Copiah County Industrial Park in Gallman, new manufacturing equipment and infrastructure improvements. The company’s current Copiah County facility produces small power transformers and employs 475 people, that report says. Soft FLAG on headcount: the PR Newswire release says the Gallman project will create “over 700 jobs”; Reeves, as quoted in Meridian Star, said the company plans to create 654 jobs. The desk prints both attributed figures and does not force a single reconciled total.

Named actors on the record in the opened company release and Mississippi coverage include Andreas Schierenbeck, CEO of Hitachi Energy (“Demand for electricity is growing rapidly, and the grid must grow with it”); Toshiaki Tokunaga, president and CEO of Hitachi, Ltd.; Mississippi Governor Tate Reeves; U.S. Energy Secretary Chris Wright; Interior Secretary Doug Burgum; EPA Administrator Lee Zeldin; Mississippi Development Authority Executive Director Bill Cork; and members of Mississippi’s congressional delegation. The company release ties demand drivers to advanced manufacturing, industrial electrification, data centres and grid modernisation — company framing, not a desk forecast.

Prior U.S. manufacturing moves listed in the same PR Newswire release for context only: a $457 million large-power-transformer expansion groundbreaking in South Boston, Virginia (June); a $106 million Alamo, Tennessee, components expansion; and a $70 million high-voltage equipment expansion in Westmoreland County, Pennsylvania. Together those projects are described by the company as creating over 1,600 jobs across the broader footprint.

Mississippi Development Authority Executive Director Bill Cork, in the Meridian Star report, framed reliable energy infrastructure as starting with the ability to manufacture the equipment that keeps the grid running, and called the $528 million expansion a massive addition that puts Copiah County at the centre of a critical manufacturing supply chain. The Meridian Star piece also notes Hitachi Energy is using Mississippi’s Flexible Tax Incentive (MFLEX) programme, with MDA assisting on site development and infrastructure and Copiah County assisting as well — incentive colour attributed to that report, not scored here as a subsidy audit.

What to watch without mood: late-2026 construction start notices; any Mississippi Flexible Tax Incentive (MFLEX) or MDA site-development filings that publish firmer job and square-footage schedules; 2029 production start confirmation; whether Crystal Springs transition dates slip or hold.

Floor: $528m Gallman transformer plant — Hitachi Energy’s largest U.S. bet; build late 2026, make transformers 2029; 654 (Reeves) / “over 700” (company) jobs attributed.
