Vertiv Expands PowerBar Track for AI Data Centre Growth
Vertiv has today announced their expansion of the Verti PowerBar Track busway range with a compact, high-capacity double stack design aimed at modern data centres.
In data centres, a busway system distributes electrical power along a track allowing tap-off boxes to connect racks and equipment to the main supply.
The company is focusing on enabling higher power density and adaptable distribution as AI workloads are reshaping requirements within colocation and hyperscale facilities. For example, AI requires higher rack densities and constrained white space which place pressure on power distribution.
Vertiv states that the system meets global safety and performance standards, and the double stack design seeks to help operators balance growing power demand with the need to preserve valuable white space for revenue-generating IT equipment.
Flexible overhead power for dense environments
The Vertiv PowerBar Track double stack configuration can provide flexible overhead power distribution for high-density compute environments.
Vertiv explains that the PowerBar Track enables safe, continuous power delivery and live configuration changes without system downtime. Its open-track architecture allows operators to install or relocate tap-off boxes anywhere along the busway while maintaining active load distribution. This means power continues to flow to connected equipment while changes take place, reducing the need for planned outages.
Each connection point includes built-in mechanical and electrical interlocks designed to enhance operator safety. The optional integrated metering allows operators to monitor load levels and make informed decisions about adding new equipment or redistributing power.
The double stack configuration supports higher capacity and more connections per tap-off box. It also scales vertically to serve high-density environments, where racks require greater power per cabinet to support AI and high-performance computing workloads. In this way, the system increases capacity without expanding its footprint across the ceiling space.
Kyle Keeper, Senior Vice President and Power Management Business Unit Leader at Vertiv says: “Power distribution must keep pace with the scale and density of modern AI and high-performance computing environments. As customers navigate increasing power demands, tighter space constraints, and rapidly evolving infrastructure requirements, they need solutions that provide flexibility.
“Vertiv PowerBar Track double stack is designed to address these challenges by enabling compact yet scalable expansion, supporting live changes and delivering the reliability required in mission-critical data centre environments.”
Integration across the power train
Vertiv positions the PowerBar Track within its broader end-to-end power train, which is the chain of electrical infrastructure that carries power from the utility supply through switchgear and uninterruptible power supply systems to IT racks. The busway integrates with Vertiv PowerBoard switchgear, forming a coordinated infrastructure for high-density applications.
Switchgear controls and protects electrical equipment, while an Uninterruptible Power Supply (UPS) provides backup power during utility outages. The company aims to deliver a unified approach to power distribution and protection across the data centre by linking the busway to these components.
The PowerBar Track can be configured to aid maintenance, helping reduce maintenance-related downtime while enabling faster deployment. Anability to install and adapt infrastructure without extended outages is a central requirement for operators managing rapid expansion.
The system also contributes to the Verti 360AI power ecosystem, which combines power distribution and management technologies designed to support AI-ready digital infrastructure.
Beyond traditional builds, Verti PowerBar Track is integrating with VertivOneCore, a scalable prefabricated data centre infrastructure solution, and Verti SmartRun, a modular overhead IT infrastructure system.
The expansion strengthens Vertiv’s focus on high-capacity power distribution for AI-driven data centre environments.
