Introducing PowerX Energy Blade
PowerX Energy Blade is a scalable, modular high-power ORV3 blade battery system with isolated power conversion. It supports both grid service applications and connection to 48V OCP servers. Within an ORV3 rack, it can serve as a Battery Backup Unit (BBU), while also enabling grid service capabilities that are typically available only through larger-scale energy storage systems.
Unlocking Grid and Compute Value
1
PowerX Energy Blade can convert any compute infrastructure into a bidirectional, flexible grid asset by responding to power system fluctuations in milliseconds. It supports grid services such as FCR, demand response, and local peak shaving, triggered either by TSO signals or autonomously through grid measurements.
2
PowerX Energy Blade can function as a high-capacity, long-duration Battery Backup Unit, or BBU, within an ORV3 rack.
3
PowerX Energy Blade’s DC output can scale from 200V to 800V. It can provide stable 48V DC power to IT racks while maintaining grid service capabilities.
How It Works in AI Data Centers
Trigger
Autonomous detection of a grid event or a signal from the TSO.
Phase A: 50–100 ms
Energy Blade responds immediately by supplying power, temporarily offsetting grid power demand.
Phase B: 4–7 seconds
Energy Blade’s smart software begins reducing power consumption through compute optimization.
Phase C
Compute optimization is completed and maximum power reduction is achieved. Energy Blade then reduces its output as needed and continues monitoring until the grid event ends.
Customer Benefits
Revenue Generation
PowerX Energy Blade enables new revenue opportunities through participation in ancillary services markets, including FCR and demand response.
Faster Grid Interconnection
By optimizing and smoothing peak power draw from the grid, PowerX Energy Blade can support faster grid interconnection, improved power supply contract terms, and greater server deployment capacity.
Greater Use of Renewable Energy
PowerX Energy Blade stores renewable energy and enables it to be used over longer durations, helping expand the use of environmental value such as RECs and Japan’s non-fossil certificates. This effect can be further enhanced when combined with PowerX’s BESS solutions.
Revenue Potential
Rack-mountable blade-type battery systems can turn data centers into a grid asset.
Investment payback is achievable across the full range of FCR market prices.
