Hitachi plans to double U.S. production of small and medium-sized power transformers; its Mississippi facility will manufacture 10–160-megavolt-ampere units.

Utility Dive reports that Hitachi plans to double U.S. production of small and medium-sized power transformers. The Mississippi facility will manufacture units rated from 10 to 160 megavolt-amperes (MVA), designed for voltages up to 230 kilovolts (kV).

The MVA range describes transformer ratings, not the facility’s annual manufacturing output or a data center’s megawatt capacity. The report’s doubling claim concerns production of the stated transformer categories, rather than all Hitachi equipment manufactured in the United States.

A Hitachi official said the additional capacity was expected to help alleviate industry-wide supply constraints. That is an attributed expectation, not evidence that the constraints have already eased. The supplied excerpt does not quantify current annual production, investment cost or the expansion’s completion date.
