BYD Energy Storage has signed a cooperation agreement with Greenvolt Power to jointly develop a 600 MW/2.4 GWh energy storage facility in Siedlce, Poland. The project, which marks the partners’ second collaboration in the country following two earlier installations totaling 1.6 GWh, is slated to begin construction in the third quarter of 2026 and enter commercial operation by the end of 2027. Upon completion, it will be the largest battery energy storage installation in Poland.
Under the agreement, BYD will supply its Haohan energy storage system, featuring the 2,710 Ah Blade Battery. The system’s minimum unit capacity is 14.5 MWh—equivalent to 10 MWh in a standard 20-foot shipping container—enabling a compact design that reduces land use, enclosure requirements, and construction costs.
João Manso Neto, CEO of Greenvolt Group, commented that energy storage systems are essential for building a more resilient and flexible power grid and can drive continued growth in renewable energy deployment. Yin Xueqin, general manager of BYD’s energy storage and new battery division, said the Siedlce project represents a significant milestone in the two companies’ partnership and reflects industry recognition of BYD’s technological strength.
Since entering the energy storage sector in 2008, BYD has deployed large-scale projects in more than 110 countries and regions. Last month, BYD and Greenvolt Power commissioned Hungary’s largest battery energy storage installation—a 99.8 MW/288.6 MWh system based on BYD’s MC Cube technology.
The Siedlce project follows a strategic cooperation agreement signed in May between BYD Energy Storage and Norway’s Corvus Energy to advance high-rate marine lithium iron phosphate battery systems. Other Chinese manufacturers are also expanding overseas; for example, Eve Energy recently secured an 8 GWh energy storage order in India.
