FAQ

Questions about our projects.

Want to know more about how we deploy with our customers?

Contact us

  • Our approach is turnkey. A single project manager runs the programme end-to-end: technical & economic study, module sourcing, manufacturing in our Spanish workshop, delivery, commissioning, and operation. You keep a dedicated point of contact for the full life of the installation, with contractual milestones at every stage.

  • We deploy BESS (Battery Energy Storage Systems) across many industries: manufacturing, logistics warehouses, tertiary buildings, farms, and aerospace facilities. Every unit is custom-sized to the specifics of each operation.

  • Once the technical & economic study is validated, allow 8 to 14 weeks for manufacturing, delivery and commissioning. The exact schedule depends on the ordered capacity and site access constraints.

  • Installing a BESS mainly requires a declaration with the grid operator (Enedis or ELD), a Consuel certificate for electrical compliance, and — depending on installed capacity — a simplified ICPE declaration. Battwoo handles these steps within the turnkey scope and coordinates with the relevant authorities.

  • Every Battwoo unit is connected to an EMS (Energy Management System) we make available to customers. You see in real time the state of charge (SoC), power exchanged, SoH and cycle count from a web dashboard. An annual preventive-maintenance package (workshop visit, voltage balancing, SoH check) is available as an option.
