TESVOLT TALLON is a containerized LFP battery energy storage system supplied as a DC block for utility-scale applications. It has 5.015 MWh nominal energy, about a 2-hour duration, and 2.5 MW rated DC power. The system delivers 93.7% DC round-trip efficiency and uses liquid cooling.

Use Cases

The specifications of TESVOLT TALLON suggest use in front of the meter, connected to the utility network itself. By energy capacity, it belongs to the utility-scale class.

Capabilities

For TESVOLT TALLON, the specifications suggest capacity value, counting as firm supply toward a network's peak needs; its shortest listed configuration is 2 h. A DC block that connects through a separate inverter makes it a candidate for renewable colocation, sitting next to a wind or solar plant and sharing its grid connection. That 2 h configuration points to peak shaving, cutting the power drawn from the grid at peak times. The specifications indicate grid services, support for the operation of the electricity network.

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.
