Hitachi Energy Plans Major US Grid Equipment Expansion

More than $1bn investment aims to ease transformer shortages and speed renewable connections

1 Dec 2025

Hitachi Energy has unveiled a US investment plan worth more than $1bn to expand domestic production of grid equipment, responding to rising electricity demand from data centres, electric vehicles and industrial facilities.

The company said the programme centres on a new transformer plant in South Boston, Virginia, which it expects will become the country’s largest producer of the heavy equipment used to move power across the grid. Expanded operations in Tennessee and Pennsylvania will support the site, with the aim of reducing long wait times that have slowed renewable projects and new transmission lines.

Washington has warned for several years about tight supplies of transformers. The Department of Energy has described the shortage as a national vulnerability, citing dependence on foreign suppliers and exposure to shipping delays. Officials argue that more domestic manufacturing could create a steadier supply chain and give utilities greater certainty as they plan grid upgrades.

The move is also expected to shift competitive pressures. Groups such as Siemens and GE Vernova may be pushed to add capacity as utilities seek shorter delivery schedules and greater US sourcing. Industry analysts say a stronger domestic base could help advance long-delayed transmission corridors and reduce the backlog of solar and wind projects waiting for grid connections.

Challenges remain. The Virginia plant is scheduled to begin operations in 2028, and the company will need to recruit and train a large workforce. Global supplies of key materials remain tight, while demand forecasts continue to evolve as electrification accelerates.

Analysts nonetheless view the investment as a significant step for a grid facing new strains. They say that if the strategy succeeds, it could ease equipment bottlenecks, support reliability and allow faster adoption of new technologies.
