ABB puts 800-volt DC between the grid and AI racks.
ABB introduced Infinitus, an 800-volt direct-current portfolio designed to carry power from the utility-facing source to high-density AI racks while reducing repeated AC/DC conversions.
The portfolio combines medium-voltage powertrains, DC sources and power quality, DC distribution, protection and cooling optimization around a common architecture. ABB says the design is intended for a shift from today’s roughly 200-kilowatt racks toward one-megawatt systems.
This is a product architecture and rollout plan, not a live full-scale campus. ABB expects main components to enter production over the next 12 months and the first complete DC-native facilities to operate in two to three years. Its efficiency and revenue estimates are company-backed and have not yet been demonstrated in an operating 500-megawatt site.

01
What changed
Data-center operators already use DC inside servers and battery systems, and ABB has been working with NVIDIA on next-generation power designs. What changed on September 23 is a named, integrated 800 VDC portfolio spanning the source-to-rack chain, with a component-production window and a stated path to complete DC-native facilities.
02
Why it matters
AI infrastructure is pushing individual racks toward power densities that make every conversion, conductor, protection device and cooling decision consequential. A source-to-rack DC design could reduce losses and equipment count while freeing more campus capacity for compute, but it also creates new requirements for protection, interoperability, maintenance and operator training. ABB’s announcement gives suppliers and developers a concrete architecture to evaluate instead of a generic efficiency promise. The commercial opportunity is substantial if it works at campus scale; the evidence threshold should be equally high. Production components, independent efficiency measurements and sustained operation at a live site will matter more than modeled savings.
03
What to watch
Watch component production, named customer pilots, protection certifications, interoperability with rack and cooling suppliers, measured source-to-rack efficiency and the first energized DC-native campus. Any delay between component availability and full-site commissioning will reveal where the architecture is hardest to industrialize.
ABB publishes the architecture, voltage, building blocks and rollout timetable, while independent industry reporting confirms the launch and identifies the efficiency claims as company-backed. Confidence is high in the product announcement and lower in prospective site economics.

Behind today’s selection
Today’s two runners-up
Runner-up 1 · Smart infrastructure · Data-center efficiency
Europe will label data-center energy and water performance.
The European Commission proposed a common sustainability rating for individual data centers above 500 kilowatts, with the first labels expected in 2027.
Why it was not selected: The scheme could shape procurement and siting across Europe, but labels begin in 2027 and the proposal does not yet impose minimum performance standards.

Runner-up 2 · Smart infrastructure · AI campuses
Alibaba’s AI expansion becomes a 20-gigawatt infrastructure bet.
Alibaba Cloud will open its first regions in Türkiye, Finland and the Netherlands and expand five existing markets as it targets more than 20 gigawatts of global data-center capacity by 2032.
Why it was not selected: The 20-gigawatt target is strategically large and the near-term regional expansion is concrete, but Alibaba has not disclosed site-level power, water, interconnection or delivery schedules for the full buildout.
