Hitachi Energy is doubling its US manufacturing capacity for small and medium power transformers at a Mississippi plant, according to Utility Dive. The expanded facility will produce units in the 10 MVA to 160 MVA range, designed for voltages up to 230 kV — a segment that has faced severe backlogs as utilities race to connect renewables and modernize the grid.
The move directly targets a well-documented bottleneck: transformer lead times have stretched for years, delaying projects from solar farms to distribution upgrades. A Hitachi official told Utility Dive that the additional capacity “is expected to help alleviate industry-wide supply constraints,” signaling a concrete step toward closing that gap.
While the announcement is a single company’s expansion, it reflects a broader trend of manufacturers reshoring transformer production to meet surging demand. No other sources were provided, so this report relies solely on Hitachi’s statement and Utility Dive’s coverage; the claimed impact on supply constraints has not been independently verified.
