SolarToday Eastern Europe, a full-scope energy storage solutions provider, has successfully commissioned a 10.32 MWh utility-scale battery energy storage system (BESS) in Zorleni, Vaslui County. The milestone project reinforces the company’s long-term commitment to supporting Romania’s renewable infrastructure and enhancing national grid stability.
The newly operational system stores solar energy generated from a 6 MW photovoltaic park in Zorleni and releases it during peak demand periods, helping balance the local grid as renewable generation expands. The project marks a major step in SolarToday’s vision to integrate advanced storage technologies across Eastern Europe.
Building on this achievement, the company plans to deploy an additional 300 MWh of storage capacity across multiple Romanian sites currently in development.
“Romania has entered a new stage, where storing energy efficiently is just as important as producing it,” said Kamer Toker, Sales Director at SolarToday Eastern Europe. “The Zorleni project proves that modern battery systems can operate reliably under Romanian grid conditions. Our collaboration with Jinko ESS, Power Electronics, and PowerKonnekt demonstrates our ability to bring global technology to local grids.”
The project was developed and coordinated by SolarToday Romania in partnership with Jinko ESS, Power Electronics, and PowerKonnekt, marking the first successfully commissioned project in the country for all three technology partners. Jinko ESS supplied the battery systems, Power Electronics provided the medium-voltage skid for grid connectivity, and PowerKonnekt delivered the energy management system (EMS) for advanced monitoring, peak-shaving, and grid-balancing.
Romania’s energy storage sector is growing rapidly — expanding from 16 MWh in early 2024 to over 400 MWh today. With national goals targeting multi-gigawatt capacity by 2030, the Zorleni installation adds much-needed flexibility for integrating renewable power into the grid.
SolarToday continues to strengthen its European footprint, with ongoing projects including a 5 MWh utility-scale installation in Hungary and several commercial and industrial systems across Greece, Bulgaria, Germany, the Netherlands, and Türkiye, ranging from 261 kWh C&I units to 70 MWh grid-scale projects.
