The new factory will be more than twice the size of Hitachi’s existing Crystal Springs facility located approximately 6.5 miles away.
Construction is scheduled to commence later this year, with transformer manufacturing projected to begin in 2029.
Upon completion of the Gallman facility, Hitachi Energy intends to transfer transformer production there from the Crystal Springs site.
This development is part of the company’s broader US manufacturing expansion programme totalling around $1.5bn, aimed at meeting growing demand for electricity across the country.
The Gallman plant will serve as the centrepiece of this initiative, which includes other investments in Virginia, Pennsylvania and Tennessee.
The expanded capacity in Mississippi is intended to address increased requirements stemming from advanced manufacturing, data centres, industrial electrification, and efforts to modernise and extend the national power grid.
Hitachi Energy stated that these investments reflect its cooperation with federal, state and local officials to enhance domestic manufacturing, support workforce development and boost infrastructure critical to meeting rising electricity needs.
In total, Hitachi Energy estimates its ongoing US manufacturing projects will create more than 1,600 jobs and support efforts to reinforce grid resilience, reliability and security.
Mississippi Governor Tate Reeves said: “This is truly a massive win for Mississippi and the US. Hitachi Energy could have made its largest investment in America anywhere in the country – but the company chose Mississippi. Mississippi’s momentum is growing stronger every day, and it is our people who are building the future of American energy infrastructure.
“This $528m investment will create over 650 new jobs while expanding the domestic manufacturing capacity our country needs to meet growing demand.”
The Crystal Springs facility will continue production until the new plant is operational, after which the site will be used for warehousing, training or other operational purposes.
The company indicated that the ongoing use of the Crystal Springs building would maintain its commitment to the region and local workforce.
In July 2026, TenneT awarded contracts to Hitachi Energy and L&T for two new high-voltage direct current grid connections: Nederwiek3 in the Netherlands and LanWin5 in Germany.
