Grid-ScaleAC BlockUpdated Aug 28, 2026

INTILION scalepac4 is an LFP battery energy storage system with 1.016 MWh nominal energy. It is supplied as an AC block with about a 2-hour duration and air or liquid cooling. The system achieves 90% AC round-trip efficiency, uses 306 Ah prismatic cells, and weighs 11.2 tonnes (24,692 lb).

Use Cases

INTILION scalepac4 has energy capacity within the utility-scale range. It is certified to medium- or high-voltage grid connection rules (VDE-AR-N 4110), and these specifications indicate use in front of the meter.

Capabilities

Its shortest listed configuration is 2 h points to grid services, work that helps keep the electricity network running, and capacity value, counting as firm supply toward a network's peak needs. The AC block includes the inverter, which makes INTILION scalepac4 a candidate for renewable colocation, operating alongside a wind or solar plant on one site. Its shortest listed configuration is 2 h points to peak shaving, reducing the peak load at the connection point.

Both measured at the grid connection point. The plant's own power use is already included in the losses.

The calculator estimates the full "plant" round-trip efficiency (RTE) at the point of interconnection. Some values are pre-blocked depending on information on a particular ESS. The rows that are marked "each way" are one-way efficiencies; they are applied on charge and again on discharge. We then square them. To enter a bundled PCS efficiency value, use its rated-power value, not peak. If the PCS skid already includes the LV/MV transformer, set Transformer LV/MV to 100 % so those losses are not counted twice.
