PowerX, Inc. has unveiled the PowerX Energy Blade, a rack-mounted battery energy storage system designed for data centers. The system combines 48 high-capacity lithium-ion cells with a scalable, modular architecture to deliver up to 2 megawatt-hours of power in a compact 42U footprint.
Overview
The PowerX Energy Blade is currently in development, targeting availability in 2027. The company is seeking partners for implementation. This system addresses the challenges of managing electricity costs and securing stable power supply for data center operators, driven by growing power consumption across computing infrastructure due to AI adoption.
What it does
The PowerX Energy Blade uses lithium-ion cells optimized for rapid charge and discharge, enabling bidirectional response to grid supply-demand fluctuations within milliseconds. It supports the 800V DC power delivery required by the latest AI GPUs and can replace conventional battery backup units (BBUs). The system turns data centers into flexible grid resources, responding to grid signals within milliseconds and releasing or absorbing power as needed.
The PowerX Energy Blade also features the company's proprietary Compute Modulation technology, which dynamically adjusts server workloads so that grid services can be delivered without disrupting the data center's core computing operations. For data center operators, the system opens new revenue streams through participation in frequency containment reserve (FCR) or similar grid flexibility markets and demand response (DR) programs. Peak shaving and load leveling can also unlock practical benefits such as earlier grid connection under flexible connection schemes, more favorable power supply contracts, and the ability to maximize server deployment within existing power budgets.
