ABB and VoltaGrid extend collaboration on data centre power infrastructure

ABB has been awarded additional large orders by VoltaGrid – a Texas-based microgrid power generation company – for data centre power projects globally to support artificial intelligence (AI) growth.

The agreement, signed on 25 March 2026 in Houston at the global energy conference CERAWeek, extends the companies’ existing collaboration to deliver reliable, stable and rapidly-deployable power infrastructure for hyperscale AI workloads. The orders will be booked in the second quarter of 2026. Financial details were not disclosed.

ABB will supply 35 synchronous condensers with flywheel and associated prefabricated eHouse units. These systems act as critical stabilisation assets within VoltaGrid’s behind-the-meter power solutions, enabling the voltage stability required by next-generation AI chips.

ABB’s synchronous condensers are an industry-leading solution that act like shock absorbers for the grid to keep electricity stable. This is due to their ability to provide instantaneous inertia, support short-circuit events and maintain network voltage through reactive power management – which ensures continuous and resilient operation of high-density data centre loads. ABB’s scope also includes high-availability medium- and low-voltage distribution infrastructure and excitation systems to maximise system reliability and uptime.

Nathan Ough, CEO of VoltaGrid, said:

“VoltaGrid’s power platform is purpose-built to deliver large-scale power with exceptional dynamic performance and reliability for next-generation digital infrastructure.

“By integrating ABB’s advanced grid stabilisation technologies with our AI-optimised power systems, we are able to meet increasingly stringent transient performance requirements while accelerating deployment at gigawatt scale.”

VoltaGrid’s solutions are designed not only for performance and speed, but also for operational efficiency, reduced noise and a compact footprint.

With growing demand for energy and increasing grid complexity, ABB supports data centres worldwide through advanced automation, electrification and digitalisation technologies that enhance reliability, efficiency and scalability.

Per Erik Holsten, President of ABB’s Energy Industries division, added:

“Extending our collaboration with VoltaGrid demonstrates the strength of ABB’s businesses working together combining automation, electrification and motion expertise and technologies with innovative distributed power systems to create greater value for customers.

“Together, we are enabling reliable, resilient and scalable power infrastructure for data centres serving the rapidly growing AI economy.”

Data centres accounted for approximately 1.5% of the world’s electricity consumption in 2024, with the United States responsible for around 45% of this total.
