Hitachi Energy Jefferson City Transformer Plant →
USJefferson City, Missouri · manufacturing
US-based LPT manufacturing; formerly ABB Jefferson City. Produces 100–800 MVA units. One of the few high-voltage LPT plants in the continental US. DOE-qualified. Capacity is limited and typically allocated years in advance to existing utility customers.
Hitachi Energy Ludvika Works (Sweden) →
SEDalarna · processing
Hitachi Energy's primary high-voltage transformer and OLTC production facility in Ludvika, Dalarna County, Sweden. Formerly ABB Power Grids (Ludvika was ABB's main power transformer factory). Hitachi acquired ABB's Power Grids division in 2020, creating Hitachi ABB Power Grids (rebranded Hitachi Energy in 2021). Ludvika produces large power transformers, HVDC converter transformers, and OLTC units for high-voltage applications. This is Hitachi Energy's primary source of the ~18% global OLTC market share it commands.
Hitachi Energy South Boston, VA →
USmanufacturing
Primary US manufacturing site for large power transformers and EHV bushings under Hitachi Energy (formerly ABB). One of the few US facilities capable of manufacturing and factory-testing 765 kV class transformers.
Hitachi Energy Varennes Transformer Plant →
CAVarennes, Quebec · manufacturing
Major Canadian LPT plant; serves US and Canadian utilities. Varennes produces extra-high voltage (EHV) transformers (500+ kV). Proximity to US Northeast makes it strategically important for New England grid reinforcement projects.

Did you know2023
Hitachi Energy's HVDC Light (Voltage Source Converter) technology is the backbone of European offshore wind interconnection: NordLink connects Norwegian hydro to German renewable grid; BritNed connects UK and Netherlands; IFA2 links France and UK. These submarine HVDC cable systems — each running 300-700km under the North Sea — form the physical infrastructure for European electricity market integration and are indispensable for balancing intermittent renewables. The same HVDC technology that carries green energy under the North Sea was also selected by the US Navy for shipboard electrical systems (in high-power AC-to-DC distribution architectures). Hitachi Energy HVDC technology — originally developed to supply a Swedish island in 1954 — now enables the European energy transition AND is being studied for US military electrical architecture applications.
Hitachi Energy Ltd. ↗Capacity2025
In March 2025, Hitachi Energy announced an additional $250 million investment to increase global transformer production capacity. More than 40% of this spending will occur in the US, specifically expanding facilities in Virginia (South Boston), Missouri, and Mississippi focused on critical transformer components including bushings and insulation. This follows a series of capacity expansions responding to the AI data center and grid modernization-driven transformer shortage. Hitachi Energy's bushing production expansion is the direct consequence of transformer backlog extending to 2+ years — bushings are a co-bottleneck with GOES and insulating kraft paper.
Fortune Business Insights ↗Note2024
Hitachi Energy's Ludvika Works in Sweden is the legacy ABB Power Grids facility that designed and produced some of the world's first high-voltage transformers and OLTCs since the early 20th century. ABB's Power Grids division (including Ludvika) was acquired by Hitachi in 2020 for $11 billion, creating Hitachi Energy in 2021. Ludvika now produces HVDC converter transformers, HVDC cables, GIS, and OLTCs for 18% of the global OLTC market. The Hitachi Energy/ABB heritage gives it particularly strong qualification credentials for ultra-high-voltage OLTCs — a direct competitive overlap with Reinhausen at the top of the voltage range.
Hitachi Energy ↗Origin2023
Hitachi Energy was created in 2020 when Hitachi Corporation (Japan) acquired ABB's Power Grids division for $11B — a business with 130+ years of history as part of ABB and its predecessor ASEA. ASEA (Swedish electrical company, founded 1883) pioneered HVDC technology, completing the world's first commercial HVDC link to Gotland Island, Sweden in 1954. ABB (formed from ASEA's 1988 merger with Brown Boveri) continued as the global HVDC leader. Hitachi bought the division to accelerate Japan's and global energy transition ambitions. The resulting entity combines ABB's century-plus of grid technology with Hitachi's Japanese industrial manufacturing and digital capabilities — a Swedish/Swiss heritage in global Japanese ownership, serving energy infrastructure worldwide.
