ABB launches HiPerGuard 34.5kV for AI data centers

ABB announced the HiPerGuard 34.5kV for AI data centers in Washington, DC, introducing a medium-voltage uninterruptible power supply (UPS) that connects directly to the grid. This development simplifies power infrastructure for the burgeoning AI sector. ABB stated the product supports voltage levels up to 34.5 kV and will be available to order in summer 2026.

The new HiPerGuard 34.5kV system addresses the increasing power demands of artificial intelligence workloads. Traditional data center power architectures often involve multiple conversion steps, leading to energy losses and increased complexity. ABB’s direct grid connection approach aims to streamline this process, offering a more efficient and potentially cost-effective power delivery method for high-density computing environments.

Why It Matters

The introduction of the HiPerGuard 34.5kV marks a significant advancement in medium-voltage UPS technology for data centers, particularly those supporting AI. While products like Schneider Electric’s Galaxy VS offer modular UPS capabilities, ABB’s HiPerGuard 34.5kV distinguishes itself by enabling a direct connection to the grid at higher voltage levels (34.5 kV). This direct connection bypasses some of the intermediate power conversion stages common in existing UPS systems, which typically operate at lower voltages. The primary benefit is a reduction in energy losses during power transmission and distribution within the data center. This efficiency gain is crucial for AI data centers, which consume substantial amounts of power. By simplifying the power infrastructure, ABB’s offering also promises to reduce the physical footprint and installation complexity of power systems, allowing for faster deployment and potentially lower capital expenditures.

ABB’s announcement positions the HiPerGuard 34.5kV as a response to the specific power challenges posed by the rapid growth of AI. The system’s ability to handle 34.5 kV directly from the grid means it can integrate more seamlessly with utility power feeds and substation infrastructure, reducing the need for extensive low-voltage distribution networks within the data center campus. This direct connection capability is a key differentiator, offering a pathway to enhanced operational efficiency and scalability for the next generation of AI-driven computing facilities.

The product’s availability in summer 2026 suggests a strategic rollout, allowing time for further testing and market preparation. The focus on AI data centers highlights a targeted approach to a rapidly expanding market segment with unique and demanding power requirements. ABB’s move into this specific voltage class and direct grid connection architecture for UPS systems signals a shift in how high-power data centers will be architected and operated in the near future.

Critical Perspective

Vendor announcements like this one set roadmap expectations but do not constitute deployed capacity. Three audit questions for procurement officers reviewing this product: (1) what fraction of stated capacity has shipped to a named, willing-to-be-cited customer, not just a press-release pilot; (2) what are the service-network and parts-availability terms in the target geographies; (3) how does the published efficiency or performance curve translate to the buyer’s actual load profile. The vendor has the strongest incentive to publish the most flattering case; the burden of proof for procurement decisions is on field operating data, not announcement-day specs.
