The wind farm features two turbines, each with a capacity of 3.45 megawatts, producing approximately 21.7 gigawatt-hours of electricity annually, sufficient to meet the needs of about 7,500 households. The integrated battery storage system, with a capacity of up to 2.2 megawatts, allows electricity generated by the turbines to be stored and released as needed. The system is expected to undergo up to two charging cycles daily, with around 10% of the wind farm’s output managed through the storage system.
EnBW highlighted that combining wind farms with battery storage enhances grid stability and provides operators with greater flexibility in managing electricity feed-in, thereby improving the economic efficiency of the turbines. The company is now incorporating battery storage systems as a standard feature in its solar parks, though the charging and discharging patterns differ. Solar parks typically store energy during peak midday production for evening release, while wind farm batteries can charge at night and supply the grid in the morning.
The Häusern wind farm’s battery storage system represents a significant step in optimizing renewable energy utilization. By storing excess wind power and releasing it strategically, the system helps balance supply and demand, reducing strain on the grid. EnBW’s adoption of this technology at Häusern underscores its commitment to advancing sustainable energy solutions and improving the reliability of renewable energy sources.
The integration of battery storage at the wind farm aligns with broader efforts to enhance the flexibility and profitability of renewable energy projects. EnBW’s plans to expand this approach to other facilities, particularly solar parks, reflect a strategic focus on leveraging storage technology to support the transition to a more sustainable and stable energy grid in Germany.
