Xos Launches 2.5MWh Power Hub for Data Centers

Xos has launched the 2.5MWh Power Hub, a behind-the-meter energy storage system scaling from 1.2 to 4 MWh that the company says can power data centers within days, not years.

Xos has launched the 2.5MWh Power Hub, a behind-the-meter energy storage and hybrid power system that scales from 1.2 to 4 MWh and can energize industrial sites and data centers within days rather than the three to seven years U.S. grid interconnection now routinely requires. The Los Angeles-based company Xos, which builds electric commercial vehicles and mobile charging systems, says each unit ships inside a standard intermodal container and runs on the same architecture as its Xos Hub mobile charging platform. According to the company, that platform already supports more than 250 MWh of energy storage operating in commercial service across North America.

Highlights

  • The 2.5MWh Power Hub series scales from 1.2 MWh to 4 MWh; the flagship 2.5 MWh unit is rated at 1.2 MW continuous output with standard 480V three-phase power.
  • Each unit ships in a standard intermodal container and, the company says, can energize a site within days rather than the three to seven years U.S. grid interconnection typically demands.
  • The system runs on the same architecture as the Xos Hub, which Xos reports supports more than 1,400 deployed assets and over 250 MWh of energy storage across North America.
  • Grid bottlenecks tied to data center demand cost PJM-region consumers $14.7 billion in a single 2025 capacity auction, up from $2.2 billion two years earlier.

A New Category of Behind-the-Meter Power

Industrial operators and data centers are facing multi-year waits for grid connections. Xos cites grid bottlenecks driven by data center demand that cost PJM-region consumers $14.7 billion in a single 2025 capacity auction, up from $2.2 billion two years earlier. The company also points to the International Energy Agency’s projection that global data center electricity consumption will roughly double by 2030, with AI as the primary driver, even as transformers, switchgear, and grid connections carry lead times of up to five years. Xos argues that behind-the-meter generation has shifted from a contingency to a strategic necessity for operators that cannot wait for a connection.

The Power Hub is designed as a single, factory-integrated unit. Xos says it combines power conversion, plant controls, and generator dispatch logic in one package with 480V three-phase output, removing the separately procured battery blocks, power conversion systems, and microgrid controllers that conventional battery energy storage deployments require. The company frames that integration as cutting months of project timeline and the associated engineering cost.

The unit is built to work alongside on-site generation. According to Xos, the Power Hub pairs with natural gas reciprocating engines, absorbing load swings from GPU-driven and transient-heavy workloads so generators can run continuously at peak efficiency rather than inefficiently at partial load.

Three Configurations

The series will be offered in three core configurations, all designed to be combined through an external power combiner into larger multi-megawatt plants:

2.5MWh Power Hub2.5 MWh1.2 MWHybrid operation with optional 500 kWe dual-fuel genset; intermodal-ready
4.0MWh Power Hub4 MWhNot specifiedApplications requiring maximum stored energy per square foot

Built on the Xos Hub Platform

Xos says the Power Hub uses the same battery, power electronics, and controls as the Xos Hub mobile charging platform. The company reports that the underlying architecture powers more than 1,400 assets and over 250 MWh of deployed energy storage, operating in duty cycles that include fleet charging for autonomous vehicle operators and emergency-response applications.

“The single biggest constraint in US industry right now is the inability to deliver power where it’s needed, when it’s needed,” said Dakota Semler, Chief Executive Officer of Xos. “We engineered this product to do three things that conventional energy storage systems cannot: arrive on a standard truck, energize without a microgrid controller, and make every kilowatt-hour of fuel-fired generation cleaner and more efficient. This is not a battery. It is a deployable power plant.”

Target Markets

Xos is aiming the Power Hub at AI data centers and industrial build-outs facing grid delays, commercial sites expanding ahead of grid upgrades, utility-scale deployments combining multiple units, and defense, government, and mission-critical installations. The company says the units are also available for short-term rental and leasing for mobile and event power. Products are manufactured in Tennessee and sold through federal procurement vehicles including the GSA Schedule, Sourcewell, and OMNIA Partners. Xos says it is expanding its network of rental, leasing, and deployment partners, with initial partner announcements expected in the coming quarters.
