Store Energy.
Deliver Power. Anytime.
Utility-scale battery storage for renewable integration, data centers and grid resilience.
Clean power, captured.
Solar and wind generate more energy than the grid can use in the moment.
Routed into storage.
Surplus electrons travel through transmission into Calyco containers.
Cells activate.
Thousands of cells charge in sequence until the container is full.
Dispatched on demand.
When the sun sets, stored power flows to cities, factories and data centers.
Renewables are abundant. Availability is not.
Solar and wind now out-compete fossil fuels on cost, but they generate when nature decides, not when demand peaks. Without storage, clean energy is curtailed by day and replaced by fossil peakers at night.

Storage is the missing layer of the energy internet.
Batteries decouple generation from consumption. They turn intermittent renewables into firm, dispatchable power and give operators a controllable asset on both sides of the meter.
Firm the grid
Absorb midday surplus and discharge into the evening peak.
Stabilize frequency
Respond in milliseconds to keep the grid at 50/60 Hz.
Guarantee uptime
Seamless backup for critical loads and hyperscale compute.
From generation to grid, on your schedule.
By day, surplus solar and wind charge the system. By night, that stored power discharges to the grid, factories and homes.

The Calyco Container
One liquid-cooled 20-foot unit — engineered, tested and commissioned as a single dispatchable block of energy.
Five megawatt-hours, in one enclosure.
Thousands of long-cycle cells charge when power is clean and cheap, then discharge on demand. It is the grid's shock absorber — packaged to ship and commission fast.
Energy flows straight through it.
By day, surplus solar and wind pour in and the cells charge in sequence. By night, that stored power flows back out to cities, factories and data centers — sub-cycle fast.

From battery to grid, in one line.
Stored DC energy leaves the battery cabinet, is converted to grid-synchronised AC in the power-conversion unit, and ties into the network at the mast. The pulses trace the live path.
Where the energy is held.
Hot-swappable modules stack into a sealed, thermally managed cabinet — thousands of cells reporting to a single BMS.
DC becomes grid-ready AC.
The bidirectional PCS inverts stored DC into grid-synchronised AC on discharge, and rectifies it back on charge — sub-cycle fast.
Onto the network.
Converted power runs up the bus conduit to the mast and out to the grid, factories and homes that need it.
