Holding the grid
together.
Grid-forming control on the 5 MWh AC block. Virtual inertia, damping and millisecond response as a standard capability, not a bolt-on.
As thermal plant retires, the physical inertia that has stabilised the grid for a century is disappearing. The Blue Sphere platform is built with grid-forming control as a native capability of the AC block, transforming battery storage from a passive energy asset into an active grid resource that helps keep the network stable.
What grid-forming actually delivers.
Stronger grid stability
The AC block provides virtual inertia and damping, supporting stable voltage and frequency in grids that are becoming increasingly renewable-powered and less mechanically damped.
Millisecond-level response
Grid-forming inverter control delivers fast dynamic support during grid disturbances, helping maintain reliable system operation without waiting on governor-controlled thermal plant.
Weak-grid ready
Designed for stable performance in low-inertia and weak-grid environments where conventional grid-following inverters struggle and where grid support is most critical.
Scalable system coordination
Multiple AC blocks operate as a unified resource, supporting large-scale deployment and coordinated participation in grid services across a whole site.
Applications on real networks.
Renewable integration
Firm the output of co-located or nearby solar and wind, keeping the point of connection within voltage and frequency limits as generation varies.
Ancillary services
Participate in frequency response, reserve and dynamic containment products where sub-second, precise response is required.
Islanded and microgrid operation
Establish and hold voltage and frequency for a self-sufficient network, enabling campus, community and industrial microgrids.
Deferred network reinforcement
Provide local grid support at constrained nodes, extending the useful life of existing transmission and distribution assets.
Specific grid-code compliance and service participation confirmed per project and market.
