Samsung SDI SBB 1.0 is a containerized NCA battery energy storage system supplied as a DC block for utility-scale use. It provides 3.841 MWh nominal energy and 1.92 MW rated DC power. The unit uses liquid cooling and 145 Ah prismatic cells, with a weight of 32 tonnes (70,548 lb).
Use Cases
Use in front of the meter, directly on the electricity network, is consistent with the specifications of Samsung SDI SBB 1.0. By energy capacity, it belongs to the utility-scale class.
Capabilities
A calculated duration of about 2 h at full power, from 3.841 MWh and 1.92 MW, makes Samsung SDI SBB 1.0 a candidate for capacity value, standing in as firm capacity when demand peaks. Its DC block connects through a separate inverter. That connection points to renewable colocation, sitting next to a wind or solar plant and sharing its grid connection. The specifications indicate peak shaving, cutting the power drawn from the grid at peak times, and grid services, work that helps keep the electricity network running.

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.
