Ford Energy FE-250 is a containerized LFP battery energy storage system with 5.45 MWh nominal energy and about a 2-hour duration. It is supplied as a DC block with liquid cooling and uses 512 Ah prismatic cells. The system weighs 43.5 tonnes (95,901 lb) and operates across a 1040 to 1500 V DC window.
Use Cases
Use in front of the meter, directly on the electricity network, is consistent with the specifications of Ford Energy FE-250. By energy capacity, it belongs to the utility-scale class.
Capabilities
A 2 h configuration makes Ford Energy FE-250 a candidate for peak shaving, discharging into the hours of highest demand. The specifications suggest grid services, work that helps keep the electricity network running, and indicate 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.
