Hitachi’s biggest US $528M investment will double Mississippi transformer output

Hitachi Energy will spend $528 million on a new transformer manufacturing plant in Gallman, Mississippi. The facility will become the company’s largest single investment in the United States. The plant will expand transformer production capacity as U.S. electricity demand continues to climb. More than 700 jobs will also come with the project, according to Hitachi Energy. More room to build The new facility will sit about 6.5 miles from Hitachi Energy’s Crystal Springs plant. Its footprint will exceed twice the size of the existing factory. That additional floor space will more than double transformer production capacity in Mississippi. Construction is expected to begin late this year, with production scheduled to start in 2029. The expansion will eventually move transformer manufacturing from Crystal Springs to Gallman. Hitachi Energy plans to keep the older facility in operation for supporting activities. Those activities could include warehousing, training, and other operational functions. Production will continue at Crystal Springs until the Gallman facility becomes ready. The proximity between the two sites should also simplify the transition. Gallman can take over manufacturing without forcing Hitachi Energy to abandon its established Mississippi operations. The larger facility gives the company room to increase output substantially. It also creates a dedicated manufacturing base sized for higher transformer demand in the coming years. The Gallman plant will manufacture power transformers for the electrical grid. These machines manage voltage levels as electricity moves through power networks. Transformers play a key role in moving electricity efficiently across long distances. They also help utilities deliver power at usable voltage levels for different parts of the grid. Additional production capacity could help address growing demand for grid equipment across the United States. Electricity-intensive industries are adding pressure to an infrastructure system that already needs continued expansion. Data centers represent one source of that demand. Industrial electrification and advanced manufacturing are also increasing electricity requirements. Grid modernization adds another layer of demand for transformer equipment. Utilities need new hardware as they expand networks and replace aging infrastructure. The manufacturing shift also matters because transformers can require substantial lead times. Expanding domestic production gives Hitachi Energy a larger base from which to manufacture the equipment. The company has not disclosed detailed specifications for the Gallman plant’s production machinery. Its announcement instead focuses on the facility’s size and the increase in manufacturing capacity. Gallman becomes production hub The new factory represents the centerpiece of Hitachi Energy’s roughly $1.5 billion U.S. manufacturing expansion. The Gallman project itself accounts for $528 million of that investment. Its larger footprint will give the company substantially more manufacturing capacity in Mississippi. The transition also separates future transformer production from the existing Crystal Springs operation. Hitachi Energy expects Gallman to begin transformer production in 2029. Until then, Crystal Springs will remain the active manufacturing site. Once the transition occurs, the existing plant will support the broader operation through logistics, workforce training, or other functions. That approach keeps the site useful after its manufacturing role changes. The project will also more than double the local workforce, with over 700 jobs planned at the expanded Mississippi operation. The employment growth follows the increase in physical manufacturing capacity.
