Suryamanu utility-scale BESS
    Battery Energy Storage System

    Utility-scale storage, from 1 MWh to 1+ GWh.

    Suryamanu builds utility-scale Battery Energy Storage Systems engineered to stabilise power grids, prevent outages and accelerate the transition to sustainable energy — optimised for cost, density and rapid deployment.

    Built for utilities

    Massive storage, rapidly deployed.

    Our BESS allows utilities, commercial enterprises, data centers and renewable energy developers to build massive energy-storage plants scalable from 1 MWh to over 1 GWh.

    Each unit arrives turnkey — pre-assembled, factory-tested and ready for rapid site integration with site transformers and SCADA.

    Core Architecture

    Turnkey. Vertically integrated.

    Unlike traditional battery-storage projects that require sourcing and assembling separate components from multiple vendors, each Suryamanu BESS arrives pre-assembled and factory-tested inside a robust steel enclosure.

    Applications & grid services

    Built for the way modern grids actually work.

    Suryamanu BESS supports a wide range of application profiles to balance grid demands and maximise asset profitability.
