Hitachi Energy has announced a landmark investment of over $1 billion to expand its power transformer manufacturing capacity for critical electrical grid infrastructure in the U.S.

A press release said that a centerpiece of this investment plan is the construction of a new facility in South Boston, Virginia. It will be strategically located by an existing Hitachi Energy plant that makes transformers, allowing seamless integration between transformer manufacturing and cable production, both central components in the push to modernize and expand America’s electric grid.

Hitachi—through its subsidiary Proterial Cable America (formerly Hitachi Cable America)—owns and operates a cable manufacturing plant in Manchester, New Hampshire. This facility produces copper and fiber optic communication cables for the U.S. market, and it is the only large-scale communications cable manufacturing plant that Hitachi owns in the United States.
