What Happened
CATL and Solarpro Technology AD have signed a strategic cooperation agreement for 2 GWh of sodium-ion systems, marking a milestone for next-generation storage in Eastern Europe. The companies will explore sodium-ion storage solutions tailored to diverse application scenarios across Central and Eastern Europe, with the goal of commissioning the region's first sodium-ion energy storage project. Solarpro, a leader in Eastern Europe's renewable sector, brings turnkey project delivery, system integration, and long-term operation and maintenance capabilities, while CATL contributes advanced R&D, system design, and field validation expertise.
“"Sodium-ion technology offers clear advantages in low-temperature performance and long-cycle life. We see strong potential for its deployment in Lithuania and other Eastern European markets. We look forward to working with CATL to further optimize sodium-ion storage solutions and identify the most suitable application scenarios across the region."”
“"We are delighted to partner with Solarpro on this project. The efficient teamwork between the two teams has revealed great potential in this partnership. We look forward to the successful implementation of the first sodium-ion battery project in Central and Eastern Europe."”
CATL and Solarpro connected a 602 MWh battery energy storage project to Bulgaria's national grid, increasing the country's total energy storage capacity by 10%.
The partners signed a 2 GWh sodium-ion storage cooperation agreement, targeting Central and Eastern Europe's first sodium-ion project.
The new agreement builds on the long-standing partnership between CATL and Solarpro. The companies will optimize sodium-ion storage solutions for Eastern Europe's climate conditions, grid requirements, and evolving energy landscape, advancing the large-scale adoption of sodium-ion technology in the region. CATL expects the collaboration to deepen its understanding of local market needs and real-world operational challenges.
Previously from CATL
CATL has been expanding its sodium-ion storage footprint in Europe. In July 2026, it partnered with Alfen to deploy 5 GWh of sodium-ion battery storage across Europe, and in June it unveiled the TENER Sodium Energy Storage System, described as the world's first field-validated sodium-ion storage solution.
