ABB expands power technology partnership with Applied Digital for AI-ready data centers

ABB has expanded its partnership with Applied Digital, a builder and operator of high-performance data centers, to supply power infrastructure for the company’s second AI factory campus in North Dakota, United States. The collaboration is delivering a new medium voltage electrical infrastructure for large-scale data centers, capable of handling the rapidly growing power needs of artificial intelligence (AI) workloads. As part of this long-term partnership, this second order was booked in the fourth quarter of 2025. Financial details of the partnership were not disclosed.

Applied Digital’s new Polaris Forge 2 campus near Harwood, North Dakota covers 300 MW of AI data centers, phased across two buildings scheduled to come online in 2026 and 2027, with the campus being designed for future expansion. Through this collaboration, ABB will deliver low and medium-voltage electrical architecture for one of the most advanced AI factory campuses in the world with best-in-class efficiency and a projected industry-leading low PUE (Power Usage Effectiveness).

Applied Digital recently reported that the initial 200 MW of capacity at its new Polaris Forge 2 campus will be leased to a US-based Hyperscaler. ABB’s partnership was first announced in June 2025, supporting the design and development of Applied Digital’s first 400 MW AI factory campus, Polaris Forge 1, at Ellendale, North Dakota. Both campuses use ABB’s innovative HiPerGuard medium voltage Uninterruptible Power Supply (UPS) technology and advanced medium voltage switchgear. Moving a data center’s power architecture from low voltage to medium voltage using HiPerGuard improves power density and energy efficiency. It also allows data centers to scale in larger 25 MW blocks, reducing cabling, and improving reliability.
