01 / CONNECTION CONCEPT
Centralized parallel
One battery plant at the substation bus.

Seven blocks, six plus one.
Seven healthy dual-conversion blocks serve one pod of the hall in place of its low-voltage UPS. Six carry the load and one is held in reserve.
- N+1 at the block level
- Each block feeds its own step-down transformer
- Blocks run out from the hall wall
Power quality for the load. A controlled connection for the grid.
02 / 08
One block.
The load is always fed through its own converter, so transfer time is 0 ms. The grid-side converter and the battery sit behind it on a shared direct-current connection.
- PCS: power conversion system
- Separate grid and load converters
- A shared direct-current connection
- Blocks from 2.5 MW to 5 MW and above, in steps that include 3 MW, 3.5 MW and 3.75 MW
03 / 08
The grid side.
Two utility feeds reach the ring main unit. Its bypass gives a direct path from grid to load when the block is out of service.
- Interconnection: the battery carries the load through grid disturbances
- Upstream generation sees the grid-side converter's slow average
- ERCOT large loads: 75 MW and above, under NPRR 1308

Smooth power for the AI hall.
The block smooths AI load pulses, rides through grid events and carries the hall through a loss of supply with zero transfer time. The hall sees clean power. The grid sees a slow, controlled draw.
- ERCOT's proposed large-load limit: 10 MW in any 5 s
- Simulated 120 MW hall, four jobs: 0.24 MW in 5 s
- Rides through grid faults, fully compatible with rules such as ERCOT NOGRR 282
- Zero-transfer backup power
05 / 08
Ride through. Stay connected.
When grid voltage sags, the block stays connected and rides through, as ERCOT NOGRR 282 requires of large loads. The battery carries the hall for the duration, so the IT load sees nothing.
- Scenario model: 20% grid voltage for 500 ms
- Scenario model: 90% recovery in 0.36 s
- NOGRR 282 load-transfer return: begin within 0.25 s, 90% within 0.5 s
- IT load stays inside the ITIC tolerance curve

Inside a battery block.
The container separates to reveal its racks and liquid-cooling end. A rack, a module and its cell stack move apart to show how the storage fits inside.
- Durations from 1 to 4 hours, custom on request
- Can replace standby generators only where duration covers the owner's continuity requirement
- Optional second container doubles the energy
- Integrated aerosol fire suppression with gas, temperature and smoke sensing

Battalion control and aux power skid.
The Battalion energy management system (EMS) runs each block from this enclosure and coordinates the seven. The auxiliary transformer and distribution supply cooling and controls.
- Runs the block on its own if the site network is lost
- Integrates with the site controller and the EMS
- Local monitoring on the touch screen
- Block decision in under 1 ms at 4,800 samples per second
08 / 08
Built-in bypass and a reserve block.
Every block has an automatic bypass in its ring main unit, and the pod carries one reserve block. If a block is taken out of service, the bypass closes and the reserve picks up its load. The hall never sees the change.
- Automatic bypass integrated in every block
- N+1: one reserve block per pod
- 99.999% availability design basis, evaluated per site
