Grid-Scale Energy Storage
Sungrow Deploys 600 MWh Battery System in Bulgaria

Grid-scale energy storage is becoming a critical component of modern electricity networks as renewable energy generation expands. Sungrow's PowerTitan 2.0 system, deployed in the 150 MW / 600 MWh Nova Zagora battery facility in Bulgaria, uses liquid-cooled battery technology to store electricity and release it when demand rises or renewable generation fluctuates. The project helps stabilize the grid, improve energy reliability, and support the integration of larger amounts of solar and wind power into the national energy mix.
The commercial impact extends beyond a single installation. Large-scale battery facilities create new opportunities for utilities, grid operators, and energy developers to manage power more efficiently while reducing dependence on traditional backup generation. The project also reinforces Bulgaria's position in the regional energy transition and supports future renewable expansion. For Sungrow, Sunotec, and Enery, the deployment strengthens their presence in the growing European energy storage market and demonstrates the scalability of utility-scale battery infrastructure.
