Commercial Battery Storage Systems (BESS) for Business
Store energy when it's cheap. Dispatch it when it's expensive. Battery energy storage systems (BESS) reduce demand charges, enable grid independence and unlock the full value of solar generation — integrated with every other EKO19 system.
Everything in the
battery storage package
Peak shaving and demand management
BESS programmed around your load profile to eliminate demand spikes that trigger punishing network charges — often the single highest-value application for commercial storage.
Solar storage and optimisation
Store surplus solar generation for use in the evening or overnight — increasing self-consumption from a typical 30–40% to 70–90% with correctly sized storage.
Time-of-use tariff arbitrage
Charge from the grid during cheap overnight periods (Agile, Economy 7, time-of-use tariffs) and discharge during expensive peak periods — creating a direct saving on every cycle.
Backup and resilience
Automatic failover during grid outages — protecting critical systems, production processes and data infrastructure from the cost of unplanned downtime.
Grid services and revenue
Enrolment in National Grid flexibility markets (FFR, DC, BM) — generating revenue from your battery when it isn't needed for on-site optimisation.
Modular and scalable
Systems from 50kWh to multiple MWh — designed to scale with your site as demand grows, without replacing the core infrastructure.
The outcomes you
can measure
Eliminate demand charge spikes
Demand charges can represent 30–50% of a commercial electricity bill. BESS targets these spikes precisely — dispatching stored energy during the exact peak minutes that trigger the highest network charges.
Maximise the value of your solar
Without storage, surplus solar is exported at low rates or curtailed entirely. With correctly sized BESS, 70–90% of solar generation is consumed on-site — at full grid avoidance value.
Genuine grid independence
The combination of solar and storage moves you from grid-dependent to grid-optional. In the event of an outage, critical systems continue without interruption.
