AustriaThe article discusses the implementation of a battery storage system at a wastewater treatment plant in Austria, which enables energy autonomy during sunny days. The project was decided upon in December 2025, delivered in April, and began operation in June. Christian Schrefel, a local councilor and leader of the municipal wastewater management association (GAV), highlights that solar panels installed around the facility since 2013 have already saved significant costs and electricity. The new battery storage further enhances this by allowing complete independence from the public power grid on sunny days. The system has a total solar capacity of 400 kWp and a storage capacity of approximately 1,000 kWh, enabling full self-sufficiency on good sunny days. It is estimated to save around €40,000 annually. Schrefel encourages other municipalities to adopt similar measures, citing interest from both Czech leadership groups and local politicians like Georg Ecker, who notes the potential for substantial cost savings and reduced strain on the power grid.
