CRRC Zhuzhou Institute CESS-L3727-EU-0.5C is an LFP battery energy storage system with 3.727 MWh nominal energy and a 2-hour duration. The containerized unit uses liquid cooling and 280 Ah prismatic cells. It weighs 36 tonnes (79,366 lb).
Use Cases
CRRC Zhuzhou Institute CESS-L3727-EU-0.5C has energy capacity in the utility-scale class. It supports IEC104 and IEC61850, used in utility control systems. These specifications indicate use in front of the meter, on the utility's side of the connection.
Capabilities
The shortest listed configuration of CRRC Zhuzhou Institute CESS-L3727-EU-0.5C is 2 h, which points to peak shaving, cutting the power drawn from the grid at peak times, and the specifications indicate grid services, support for the operation of the electricity network. That configuration makes it a candidate for capacity value, counting as firm supply toward a network's peak needs. Its DC block connects through a separate inverter, which points to renewable colocation, sitting next to a wind or solar plant and sharing its grid connection.

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.
