Data Centres: Boom and Backlash- How long does it take to get a power transformer in 2026?
- Lead times for large power transformers reached five years in 2026, driven by simultaneous demand from hyperscaler data-centre buildouts and renewable energy grid connections. All three major suppliers — GE Vernova/Prolec, Hitachi Energy, and Siemens — face the same constraint.Source: Lowdown data-centres
- What is Hitachi Energy and who owns it?
- Hitachi Energy is the successor to ABB's Power Grids division, acquired by Hitachi Ltd in 2020 and rebranded in 2021. Hitachi completed full ownership in December 2022. The company makes transformers, HVDC systems, and high-voltage grid equipment from its Zurich headquarters.Source: Wikipedia
- Why are power transformers so hard to get for data centres?
- Transformer manufacturing requires specialised electrical steel, copper windings, and highly skilled engineers. Production can't be ramped quickly. The simultaneous surge in data-centre construction and renewable energy grid connections across North America and Europe has overwhelmed existing capacity at all three major suppliers.Source: Lowdown data-centres
Background
Hitachi Energy is a global power technology company headquartered in Zurich, Switzerland, wholly owned by Hitachi Ltd since December 2022. The company traces its origins to ABB's Power Grids division, which Hitachi acquired in 2020 and rebranded in 2021. With $16 billion in annual revenue and 58,000 employees, it is one of the three largest suppliers of high-voltage grid equipment, transformers, and HVDC systems in the world.
Hitachi Energy's transformer business is central to the data-centre supply bottleneck. Alongside Prolec GE (now part of GE Vernova after a $5.28bn acquisition in April 2026) and Siemens, Hitachi Energy faces lead times stretched to five years for large power transformers, a constraint created by the simultaneous acceleration of hyperscaler data-centre construction and renewable energy grid interconnection. Data-centre electrification orders across the industry hit record levels in Q1 2026.
The company's HVDC technology is also relevant to the data-centre grid challenge: long-distance HVDC connections from renewable generation zones to data-centre clusters are one proposed route around local grid congestion. Hitachi Energy delivered the HVDC infrastructure for the North Sea Link submarine cable between Norway and the UK, demonstrating capability in exactly the kind of grid infrastructure that data-centre operators need at scale.
