Green Capital has awarded a contract to domestic contractor Electrum Group for the development of an 80 MW/320 MWh battery energy storage system (BESS) in Poland’s Lower Silesia province. The project highlights the growing role of large-scale storage in enhancing grid reliability and supporting renewable integration.
Comprehensive EPC Scope and Timeline
The deal includes the whole engineering, procurement, and construction (EPC) scope, which includes designing the system, building it, and connecting it to the grid. The company says that construction will start in the second quarter of 2026.
The project will be built in Lwówek Śląski and is expected to be finished in the third quarter of 2027. This is part of Poland’s larger effort to improve its energy infrastructure.
Digital Optimisation for Enhanced Performance
The BESS facility will be equipped with Electrum’s proprietary digital systems, which are designed to optimise operational performance and improve system efficiency. These advanced solutions are expected to enhance the reliability and responsiveness of the energy storage installation.
Long-Term Operational Stability
The contract between Green capital and Electrum also has a long-term service agreement (LTSA) and an operations and maintenance (O&M) agreement that lasts for five years. These plans are meant to make sure that the project goes well, stays on track, and that costs can be predicted throughout its life.
Expanding Energy Storage Capabilities
Green Capital, headquartered in Warsaw and part of the Sun Capital Polska group, is actively engaged in developing and operating renewable energy and storage projects across Poland, South Africa, and Argentina. The company continues to expand its footprint in the global clean energy sector.
Electrum Group has a lot of experience with this kind of work. They have built almost 400 energy infrastructure projects, managed more than 3 GW of capacity, and built more than 4 GW of wind and solar parks.
The collaboration reflects a broader industry trend toward integrating energy storage solutions to support renewable energy growth and grid stability across Europe.
