PowerX, Inc. (Headquarters: Tamano City, Okayama Prefecture; Director, Representative Executive Officer, President & CEO: Masahiro Ito; Stock Code: 485A) today announced the product concept for the 'PowerX Energy Blade,' a rack-mounted battery storage system for data centers. Development is underway for a planned launch in 2027, and the company is now recruiting partners for implementation.
As the proliferation of AI increases the power consumption of computing infrastructure, managing electricity costs and ensuring a stable power supply have become major challenges for data center operators. The use of 'non-firm connections,'*1 which are conditioned on curbing demand during grid congestion, is also being considered.
The PowerX Energy Blade is a rack-mounted, high-output battery storage system that addresses these challenges. It employs lithium-ion battery cells capable of high-speed charging and discharging, responding bidirectionally to fluctuations in the power grid's supply and demand in milliseconds. In addition to supporting the 800V DC power delivery required by the latest AI GPUs, it can also be used as a replacement for existing battery backup units (BBUs).
This system transforms data centers, which were previously only consumers of electricity, into grid resources that contribute to the stabilization of power supply and demand. While the battery storage responds to grid requests in milliseconds, proprietary software controls the server's computational load, allowing the data center to provide grid services without stopping its primary processing tasks.
Data center operators can secure new revenue streams by participating in the balancing market and demand response (DR) programs. By suppressing and leveling peak power with this system, operators can expect benefits such as earlier grid connection through acceptance of non-firm connections, improved terms on power supply contracts, or maximization of the number of installed servers.
Following the mass-produced containerized data center 'Mega Power DC' announced in February 2026, PowerX aims to further expand its range of battery-powered solutions with this system targeting building-type data centers. Through these initiatives, we will contribute to building the social infrastructure that supports the AI era from both a power and computing perspective.
**Item** | **Specification**
---|---
**Rack Standard** | 21-inch rack (OCP Open Rack V3 compliant)
**Battery Cell** | High-speed charge/discharge 8C class lithium-ion battery
**Storage Capacity per Module** | Approx. 3 kWh
**Storage Capacity per Rack** | Max 48 kWh (with 16 modules)
**IT Load (per rack)** | 40–120 kW
**Supply Voltage** | 200V DC–800V DC
*As the system is under development, final specifications are subject to change.
*1 Non-firm connection: A method of connecting to the grid on the condition that output is controlled or demand is suppressed during transmission and distribution network congestion, utilizing available grid capacity. It was introduced to promote the early grid connection of renewable energy and has recently seen expanded application to demand-side facilities like data centers.
The technical concept and demonstration data for this system are available in a white paper.
