Hitachi Energy
Owned by Hitachi, Ltd. (TSE: 6501)You can't buy Hitachi Energy stock directly, but you can't build an AI data center without getting in line behind its customers.
Who they are
Hitachi Energy exists because Hitachi bought ABB's Power Grids division in 2020 and rebranded it the following year, folding a century-plus of Swiss and Swedish (ASEA/BBC lineage) high-voltage engineering into the Japanese conglomerate's energy business. It isn't independently listed — there's no separate Hitachi Energy stock ticker to buy — it trades only indirectly as part of parent company Hitachi, Ltd. on the Tokyo Stock Exchange. Andreas Schierenbeck, previously CEO of Uniper and thyssenkrupp Elevator, took over as CEO in July 2024.
What they do
Hitachi Energy is one of a small handful of companies in the world capable of building the high-voltage transformers, switchgear, and substation equipment that connect a power plant or grid to a large electrical load — exactly the equipment AI data centers now need in volumes the industry has never seen. Lead times for large power transformers have stretched from roughly 12 months to 48–60 months industry-wide, and reports from April 2026 estimated more than half of the US AI data center pipeline for the year was being delayed specifically by this shortage, not by chip supply.
How Hitachi Energy makes money
Equipment sales and long-term service contracts, at a scale that puts it in the same tier as GE Vernova and Siemens Energy: the company employs more than 40,000 people and generates upward of $10 billion in annual business volume. It has committed more than $1 billion to US manufacturing alone, including a new large power transformer plant in South Boston, Virginia targeted to come online in 2028, part of a broader global capacity commitment reported at $4.5 billion or higher aimed specifically at grid infrastructure serving hyperscaler demand, including Amazon's data center buildout.
The bigger trend
Analysts have started grouping Hitachi Energy, Siemens Energy, and GE Vernova together as holding a combined transformer and grid-equipment backlog exceeding $180 billion with six-plus years of revenue visibility — an unusual position for industrial manufacturers to be in. The binding constraint isn't factory floor space; it's grain-oriented electrical steel (GOES), a raw material controlled by a handful of producers where building new capacity takes four to six years, meaning new plant announcements from Hitachi Energy and its rivals won't meaningfully relieve the shortage before 2028 at the earliest.
Whether Hitachi Energy's new Virginia plant and other capacity additions actually shift the delivery timeline for US customers once online in 2028, or whether GOES steel availability remains the harder ceiling regardless of new factory floor space. Because Hitachi Energy isn't separately listed, the clearest public read on its trajectory is parent company Hitachi's energy-segment disclosures rather than a standalone stock.

Frequently asked questions
Not directly. Hitachi Energy is not independently listed; it is wholly owned by Hitachi, Ltd., which trades on the Tokyo Stock Exchange under ticker 6501. Investing in Hitachi, Ltd. is the only public-market way to gain exposure to Hitachi Energy's business.
Large power transformer lead times have stretched from roughly 12 months to 48 to 60 months industry-wide, driven by AI data center demand colliding with a limited global supply of grain-oriented electrical steel, the key raw material, which takes 4 to 6 years to add new production capacity for.
Hitachi Energy is a business unit formed in 2020 when Hitachi, Ltd. acquired ABB's Power Grids division. It operates under the Hitachi Energy brand but has no separate stock listing of its own, unlike its rival GE Vernova.
