HiTHIUM Power 6.25MWh 4h is a containerized battery energy storage system with 6.25 MWh nominal energy in a DC block and about a 4-hour duration. It uses liquid cooling and weighs 48 tonnes (105,822 lb).

Use Cases

HiTHIUM Power 6.25MWh 4h has nominal energy in the utility-scale size class. This specification points to use in front of the meter on the utility's side of the connection.

Capabilities

HiTHIUM Power 6.25MWh 4h lists a configuration of 4 h, which points to energy shifting, charging at one time and discharging hours later. The specifications suggest capacity value, counting as firm supply toward a network's peak needs, and its shortest listed configuration is 4 h. Its DC block connects through a separate inverter, which makes HiTHIUM Power 6.25MWh 4h a candidate for renewable colocation, operating alongside a wind or solar plant on one site.

Both measured at the grid connection point. The plant's own power use is already included in the losses.

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.
