CATL and Solarpro commission Bulgaria’s largest 602 MWh battery storage
- 602 MWh battery energy storage facility in Burgas connected to Bulgaria’s electricity grid.
- Project increases Bulgaria’s total energy storage capacity by 10% and supports wind and solar integration.
- Solarpro Technology AD led engineering, procurement, construction and full integration of the battery system.
- CATL’s TENER 6 MWh‑class zero‑degradation system delivers zero capacity and power degradation in year one and reduces land use by 20%.
Project overview
A 602 MWh large‑scale battery energy storage project in Burgas has been connected to Bulgaria’s electricity grid, increasing the country’s total energy storage capacity by 10% and supporting integration of wind and solar while enhancing national grid stability.
Delivery and roles
Solarpro Technology AD led engineering, procurement and construction and carried out full integration of the battery energy storage system.
Technology
The facility uses CATL’s TENER energy storage system, described as the world’s first 6 MWh‑class zero‑degradation solution; it achieves zero degradation in both capacity and power during the first year, reduces land use by 20%, offers advanced corrosion and seismic resistance, and is presented as improving project economics with a 1.13% increase in internal rate of return.
Partnership and next steps
CATL and Solarpro plan to expand their energy storage collaboration over the next two years to support further clean energy development in Bulgaria and the region.
