The system stores solar power from a 6 MW photovoltaic park and delivers it during peak demand to help balance the local grid, which is crucial as renewable generation expands.

This project builds on SolarToday Eastern Europe's plans to deploy an additional 300 MWh of energy storage capacity at several Romanian sites currently in development. 

The country's energy storage capacity has grown significantly, from only 16 MWh at the start of 2024 to over 400 MWh today. With national targets aiming for a multi-gigawatt-scale capacity by 2030, the new system adds much-needed flexibility for integrating renewable generation.

Kamer Toker, Sales Director at SolarToday Eastern Europe, said: "Romania has entered a new stage, where storing energy efficiently is just as important as producing it. The Zorleni project proves that modern battery systems can operate reliably under Romanian grid conditions and play a decisive role in balancing renewables.

The project was completed with the collaboration of Jinko ESS, which supplied the battery systems, Power Electronics, which provided the Medium-Voltage (MV) Skid for a stable grid connection, and PowerKonnekt.

SolarToday continues to expand its energy storage portfolio across Europe, with projects including a 5 MWh utility-scale system in Hungary and various medium-scale systems for commercial and industrial clients in Greece, Bulgaria, Germany, the Netherlands, and Turkey.
