Grid-scale storage, built to order.
Containerised utility battery storage, built to your specification, delivering fast frequency response and peak capacity for network operators and independent power producers.
- 50 MWh+modular multi-container arrays
- Grid-forminginverter capability
- IEC 61850utility protocol support
Overview
Networks need capacity they can call on in milliseconds.
Demand peaks are sharper, connections are harder to secure and new network capacity takes years to build. Operators need fast, flexible capacity that can be installed quickly.
EMS iContainer is utility-scale storage built to the size you specify. LFP batteries arrive with power conversion, monitoring, communications and fire protection integrated, so installation and commissioning stay simple and more blocks can be added as needs grow.
-
01Falling system inertia as thermal plant retires
Grid-forming inverters provide synthetic inertia
-
02Peak demand outgrowing local network capacity
Storage discharges at peak to relieve constrained feeders
-
03Slow, costly network reinforcement
Storage defers upgrades by managing local peaks
-
04Complex integration with SCADA
DNP3, Modbus and IEC 61850 protocol support
EMS Energy Intelligence
Storage that thinks ahead.
Smart energy management that learns how your utility site uses power and plans every kilowatt ahead of the peak.
- Load forecasting
- Smart dispatch
- Predictive health
- Fleet-wide visibility
- Low-price window 01:00–05:00. Charging 18 MWh from the grid.
- Evening peak 17:30–19:30. Discharge scheduled at highest price window.

FAQ
Questions from utility teams.
Can’t see your question? Our engineers answer within one working day.
What services can the system provide?
Frequency response, balancing, capacity, synthetic inertia, voltage support and energy arbitrage, with control strategies stacked to maximise value.
How large can a project be?
iContainer blocks are modular and combine into arrays of 50 MWh and beyond, configured to your connection and service requirements.
Which control protocols are supported?
DNP3, Modbus and IEC 61850 for integration with utility SCADA and energy management systems.
Can it be built to our size?
Yes. iContainer is built to order, so capacity and configuration are specified to your connection and service requirements.
