Advanced energy storage system: Poland’s Wind Farm using the best of both worlds

Lead and lithium batteries provide up to 4.5 hours of power and help integrate wind power into Poland’s energy matrix




About the case study

This hybrid energy storage (ESS) system made of advanced lead and lithium batteries is currently the largest of its kind in Poland.

Strategically situated to enhance the Bystra Wind Farm in Northern Poland, this facility maximizes renewable energy usage and stabilize local energy supplies.

Through efficient energy time-shifting, the system provides a reliable power source during peak demand periods, lowering energy costs for industries and residents. It focuses on low-carbon technologies and high recycling rates, setting a new standard for energy solutions in the region.
