Roche Energy REL6250 is a containerized LFP battery energy storage system for utility-scale projects with 6.251 MWh nominal energy. Supplied as a DC block, it uses liquid cooling and 587 Ah prismatic cells. The system weighs 50 tonnes (110,231 lb).
Use Cases
Use in front of the meter directly on the electricity network is consistent with the specifications of Roche Energy REL6250. It belongs to the utility-scale class by energy capacity.
Capabilities
Its DC block connects through a separate inverter, which points to Roche Energy REL6250 as a candidate for renewable colocation, operating alongside a wind or solar plant on one site.
Nominal energy
6.25MWh

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.
