Chalmers University of Technology, one of Sweden's leading universities, has now commissioned a 40 kWh Rebaba battery for its wind turbine research facility on Björkö in the Gothenburg archipelago. The site hosts a 30 kW wind turbine designed and built by Chalmers, fitted with a custom control system and additional sensors giving researchers detailed measurement data and allowing for precise control over the turbine's operation. These features support research into making wind power more efficient, durable and better able to support the grid. The turbine itself was even designed with sustainability and resource efficiency in mind, using wood instead of conventional steel for its tower to reduce its carbon footprint, a perfect fit for Rebaba's CircularBESS. By integrating the Rebaba battery with Chalmers' own control software, researchers can now explore the benefits battery energy storage systems (BESS) can provide in a wind-plus-storage setup. The battery enables island mode: running wind, solar and storage together as a self-sufficient system capable of operating independently from the main power grid as well as in grid connected mode provide ancillary services to the grid. Wind turbines that only work when connected to the main grid are only half the story. We want to explore how wind, solar and batteries can work together to keep the lights on, even when the main grid goes down. Second-life batteries from Rebaba fit well into our existing system and give us the possibilit
