Grid-ScaleAC Block20 ft containerUpdated Aug 28, 2026
Capture Energy BESS PowerBox 1 MW/1.7 MWh, 690 VAC is a containerized LFP storage system for utility-scale use. It provides 1.72 MWh nominal energy and about a 2-hour duration. The unit uses an AC block, forced air cooling, and 280 Ah prismatic cells, and weighs 23.5 tonnes (51,809 lb).
Use Cases
The specifications of Capture Energy BESS PowerBox 1 MW/1.7 MWh, 690 VAC together point to use in front of the meter. Its nominal energy places it in the utility-scale size class. It is certified to medium- or high-voltage grid connection rules under EN 50549-2.
Capabilities
For Capture Energy BESS PowerBox 1 MW/1.7 MWh, 690 VAC, the specifications suggest renewable colocation, sitting next to a wind or solar plant and sharing its grid connection. Its AC block includes the inverter. The shortest listed configuration is 2 h and makes it a candidate for peak shaving, reducing the peak load at the connection point. That configuration points to grid services, work that helps keep the electricity network running, and indicates capacity value, counting as firm supply toward a network's peak needs.

Plant Round-Trip Efficiency
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.
Site Space Required
Shared: one 3 m aisle serves both neighbours. Dedicated: each unit keeps its own 3 m, so gaps double to 6 m.
Single unit — matches the stored area_sqm convention.
