Hitachi to double US production of small and medium-sized power transformers

Hitachi Energy is investing $528 million to build a new transformer manufacturing plant in Gallman, Mississippi, more than doubling its U.S. production capacity for small- and medium-sized power transformers. The Gallman facility will produce units in the 10 MVA to 160 MVA range for voltages up to 230 kV, be more than twice the size of the current Crystal Springs, Mississippi, plant, and is scheduled to begin production in 2029 with production moving from Crystal Springs to Gallman. The investment is the company’s largest single U.S. commitment and raises its total U.S. manufacturing expansion to roughly $1.5 billion, alongside capacity increases at facilities in Pennsylvania, Virginia and Tennessee.

The expansion targets persistent industry supply constraints and long lead times for transformers and grid equipment that are slowing power-grid expansion as data centers, manufacturing growth and electrification drive electricity demand. Hitachi frames the additional capacity as a way to alleviate backlogs and improve responsiveness to customer needs over the long term, while noting that specific production volumes and customer lead times vary by specification and project complexity.
