CATL and Solarpro sign 2 GWh sodium‑ion storage deal for Eastern Europe
- CATL and Solarpro signed a strategic cooperation agreement for 2 GWh of sodium‑ion energy storage systems for Eastern Europe.
- The partners aim to commission the first sodium‑ion energy storage project in Central and Eastern Europe.
- Sodium‑ion technology is highlighted for low‑temperature performance and long cycle life and will be optimized for regional climate and grid conditions.
- In May 2026 the two companies connected a 602 MWh battery project to Bulgaria's grid, boosting the country's storage capacity by 10%.
Deal overview
CATL and Solarpro have signed a strategic cooperation agreement covering 2 GWh of sodium‑ion energy storage systems to accelerate adoption of next‑generation storage across Eastern Europe. The partnership targets commissioning the first sodium‑ion energy storage project in Central and Eastern Europe and exploring application scenarios across the region.
Technology and deployment focus
The agreement emphasises sodium‑ion advantages in low‑temperature performance and long cycle life. CATL will apply its R&D, system design and field validation capabilities to develop solutions optimised for Eastern Europe’s climate conditions and grid requirements, while Solarpro will contribute local market insight and operational experience.
Roles and partner statements
Solarpro's CEO said the company sees strong potential for deployment in Lithuania and other Eastern European markets and will work with CATL to optimise solutions and identify suitable application scenarios. CATL’s ESS CTO said the companies are committed to successful implementation of the region’s first sodium‑ion battery project.
Background
The new agreement builds on an existing partnership: in May 2026 the two firms connected a 602 MWh large‑scale battery energy storage project to Bulgaria’s national grid, increasing the country’s total energy storage capacity by 10%.
