European Energy Connects Its First Baltic Battery Storage Project To Lithuania’s Electricity Grid

European Energy is preparing to begin operations at its first battery energy storage system (BESS) project in the Baltic States, marking an important milestone in the company’s expansion of renewable energy infrastructure in the region. Located in Anykščiai, Lithuania, the facility has a power capacity of 25 MW and an energy storage capacity of 65 MWh and has now been successfully connected to the country’s electricity grid.

The project is significant because it is only the second hybrid renewable energy facility in Lithuania to combine large-scale solar power generation with battery energy storage technology. By integrating energy storage with renewable generation, the project is designed to improve the flexibility of the electricity system and support a more reliable supply of clean energy.

According to Tadeušas Konkovskis, Vice President and Head of the Baltic Region at European Energy, the company worked closely with Lithuania’s electricity transmission system operator, Litgrid, throughout the development and connection process. He noted that because the project is among the first of its kind in the country, extensive testing and technical verification were required to ensure a smooth and successful connection to the transmission network.

The battery storage facility has been integrated with European Energy’s 78.5 MW solar park in Anykščiai, creating one of Lithuania’s first hybrid renewable energy projects. The combination of solar generation and battery storage will allow electricity generated during periods of high solar output to be stored and supplied to the grid when needed.

This is expected to enhance grid flexibility, improve energy management, and support the delivery of balancing services that help maintain stability across the electricity network.The solar park itself is one of the largest solar energy facilities in the Baltic region and holds the distinction of being the first solar project in Lithuania to participate in the system services market.

The addition of battery storage further strengthens the facility’s role in supporting the country’s evolving energy system.Thorvald Spanggaard, Executive Vice President and Head of Project Development at European Energy, highlighted the growing importance of hybrid renewable energy solutions as Lithuania continues to expand its renewable energy capacity.

He explained that energy storage systems play a critical role in managing fluctuations in renewable power generation and ensuring the stable operation of the electricity grid. Spanggaard also emphasized that Lithuania remains a key market for the company’s renewable energy activities and that European Energy is focused not only on developing new projects but also on optimizing existing assets and expanding its portfolio of renewable energy and storage investments.

The Anykščiai battery storage facility is expected to enter commercial operation before the end of the month, further strengthening Lithuania’s renewable energy infrastructure and supporting the country’s transition toward a cleaner and more resilient energy system.European Energy currently operates around 400 MW of renewable energy capacity across Lithuania and is developing an additional portfolio of approximately 800 MW covering solar, wind, and energy storage projects.

The company is also advancing a second battery energy storage project in the country. Located in Telšiai, the planned facility will have a capacity of approximately 12 MW and an energy storage capability of 50 MWh. The project is expected to be connected to Lithuania’s electricity grid in December 2026, further expanding the country’s energy storage capacity and supporting the integration of renewable energy sources into the national power system.
