On July 1, BYD Energy Storage announced that it has signed a cooperation agreement with Greenvolt Power to jointly develop the Siedlce energy storage project in Poland. With a total capacity of 600 MW/2.4 GWh, the project will become the largest battery energy storage facility in Poland upon completion, marking another successful deployment of BYD Energy Storage's technology in the European market.
This cooperation represents a renewed partnership between BYD Energy Storage and Greenvolt Power in Poland, following two previous projects in the region with a combined cumulative capacity of 1.6 GWh.
Construction of the Siedlce project is scheduled to commence in Q3 2026, with commercial operations expected to begin by the end of 2027. Leveraging its leading technological expertise and proven reliability validated through projects across multiple global markets, BYD Energy Storage was selected as the core solution provider for this project.
BYD Energy Storage will supply the project with its advanced BYD Haohan energy storage system, which incorporates the world's largest 2710 Ah dedicated Blade Battery for energy storage applications. Featuring a minimum unit capacity of 14.5 MWh and achieving an ultra-large capacity of 10 MWh in a standard 20-foot container equivalent, the Haohan system will require fewer containers and a smaller footprint, thereby significantly reducing land use and construction costs for the Siedlce project.
