GWh-scale battery storage, built from a repeatable 5 MWh AC block.
Blue Sphere works with utilities, IPPs, hyperscalers and sovereign infrastructure operators on programme-scale battery storage. Every project is built from the same 5 MWh AC block, using an architecture that has already been deployed at multi-megawatt scale across Europe, APAC and Africa by our technology partners.
What programme-scale delivery looks like.
Utility-scale energy platform
The 5 MWh AC block is designed for GWh-scale deployment, enabling efficient integration into large renewable and grid-support projects without redesigning the underlying unit.
High-density site layout
Flexible back-to-back and tail-to-tail installation with 15 cm spacing helps reduce project footprint by over 20% at GWh scale, keeping more of the site available for infrastructure and future expansion.
Flexible duration configuration
The platform supports both 2-hour and 4-hour system configurations, allowing a single asset to be tuned to capacity market products, arbitrage windows or ancillary services.
Grid-forming as standard
Grid-forming inverter control provides virtual inertia, damping and millisecond response, supporting stable operation in high-renewables and weak-grid environments.
Integrated safety and BMS
Integrated thermal management, fire mitigation design and one-to-one string management with SPAC BMS deliver system-level safety and warranty-grade visibility.
Lifecycle services
End-to-end support from commissioning to optimisation, with monitoring, alarming and lifecycle management provided through our operations platform.
Where the platform earns its return.
Renewable arbitrage
Store excess renewable generation and dispatch when demand and prices rise, improving project economics and grid utilisation.
Ancillary services
Fast and accurate frequency response to support system balance and participation in ancillary service markets.
Grid capacity and reliability
Support local networks when load exceeds capacity, improving power quality and supply reliability without waiting on transmission upgrades.
Microgrid and islanded systems
Anchor community, industrial and remote microgrids with grid-forming control that can black-start and hold the local network.
