SE Europe’s renewable energy push has hit a wall. Grid flexibility can’t keep up with solar and wind surges. Bulgaria’s latest storage project isn’t just a fix—it’s a signal of how tech is breaking that deadlock.

On June 12, 2026, Sungrow and Sunotec commissioned a 150MW/600MWh battery storage system in Nova Zagora, Bulgaria. The project is owned by Enery, a leading CEE independent power producer. It uses Sungrow’s liquid-cooled PowerTitan 2.0 tech and is funded by Bulgaria’s RESTORE program. This is the first major milestone from their 2025 Intersolar collaboration, which plans up to 800MWh in Nova Zagora and 1GWh more under consideration. Over the next two months, 2.2GWh of capacity will go online. By end 2026, total capacity will hit 3GWh. The pipeline includes Enery’s Knizhnovik Phase1 hybrid BESS-PV project (100MW/200MWh).

The commercial loop here is clear. Enery will optimize the asset across power and balancing markets. Sungrow’s PowerTitan 2.0’s compact design and cooling tech make it cost-efficient and safe. This project sets a compliance standard for Bulgaria’s grid regs. The end-game? Sungrow and Sunotec are locking in SE Europe’s storage market. They’ll likely dominate future projects in the region, using this milestone as a case study to win more contracts.
