en.Wedoany.com Reported - Sungrow and Sunotec have commissioned a 150 MW/600 MWh battery energy storage system in Nova Zagora, Bulgaria. Developed and owned by Enery, the Bulgarian energy storage project utilizes Sungrow's PowerTitan 2.0 liquid-cooled energy storage technology, with financial support from Bulgaria's Ministry of Energy under the national RESTORE program.
Located in the Nova Zagora region, this Bulgarian energy storage project marks the first major milestone in a portfolio of energy storage projects jointly advanced by Sungrow and Sunotec in Bulgaria. The 150 MW/600 MWh battery energy storage system will enhance grid flexibility, support renewable energy integration, and participate in electricity and balancing market operations. According to the project parties, the two companies previously announced a partnership during Intersolar 2025, planning to advance up to 800 MWh of battery energy storage capacity in the Nova Zagora area, with further expansion to 1 GWh under study.
Per the project schedule, Sungrow and Sunotec plan to connect a total of 2.2 GWh of battery energy storage capacity in Bulgaria over the next two months, with cumulative capacity expected to reach 3 GWh by the end of 2026. With the commissioning of this 150 MW/600 MWh battery energy storage system, Bulgaria's energy storage project construction has entered a phase of batch deployment, providing new storage infrastructure support for grid regulation and renewable energy integration in Southeast Europe.
