Outdoor battery energy storage cabinet with its front door open, on a concrete pad at the edge of a factory site

Commercial & industrial BESS

Industrial battery storage, sized to your plant’s load curve

Configured from your metering data, not from a catalogue.

How we size

Three inputs decide the configuration

  1. 01Metering data in

    Twelve months of 15-minute data, your tariff and your contracted peak.

  2. 02Configuration out

    Usable capacity, C-rate, cabinet count and grid interface, derived from the profile.

  3. 03Payback modelled

    Against your tariff before you commit; the model goes with the quote.
