LFP battery energy storage system, CNTE STAR X is a containerized system with 5.644 MWh nominal energy and about a 2-hour duration, supplied as an AC block. Liquid cooling manages 530 Ah prismatic cells. It weighs 45 tonnes (99,208 lb).
Use Cases
CNTE STAR X has an energy capacity within the utility-scale range. That capacity points to use in front of the meter, on the utility's side of the connection.
Capabilities
CNTE STAR X's shortest listed configuration is 2 h, which points to capacity value, being counted on as supply when the network is tight. Its AC block includes the inverter, and the specifications suggest renewable colocation, operating alongside a wind or solar plant on one site. That 2 h configuration makes CNTE STAR X a candidate for peak shaving, discharging into the hours of highest demand. The specifications indicate grid services, support for the operation of the electricity network.

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.
