European Energy has completed construction of its first battery energy storage system in the Baltic states. The 65 MWh battery installation has been added to the company’s 78.5 MW Anykščiai solar park in Lithuania and is scheduled to begin operations in February 2026. The battery system will enable the storage of renewable electricity and support grid stability. By integrating energy storage with an existing solar asset, European Energy is transforming the Anykščiai site from a traditional solar park into a hybrid renewable energy park, combining solar power with battery storage. The project is expected to be one of the first hybrid renewable energy parks in Lithuania.
The Anykščiai solar park is already fully operational and ranks among the largest solar projects in the Baltic region. It is also the first solar park in Lithuania to participate in the electricity balancing market. Once the battery system is commissioned, it will provide additional balancing services alongside electricity generation, enhancing both the stability and flexibility of the national electricity system. Over the past five years, renewable energy development in Lithuania has accelerated, with significant growth in both solar and wind capacity. As the share of variable renewable generation increases, the need for flexibility solutions and reliable system operation has become critical.
Battery energy storage systems allow electricity to be stored during periods of high production and released when demand rises. This capability supports grid operation, reduces the risk of curtailment, and helps moderate price volatility. Tadeušas Konkovskis, Vice President of European Energy and Head of the Baltic region, said that as renewable energy continues to expand in Lithuania, flexibility solutions are increasingly important. He emphasized that energy storage plays a central role in managing variability, supporting stable grid operation, and enabling efficient integration of renewable generation.
The battery installation at Anykščiai complements European Energy’s broader activities in Lithuania, where the company continues to develop, optimise, and selectively divest assets as part of its long-term portfolio strategy. In addition to project development, European Energy actively explores partnership opportunities and transactions that support the continued expansion of renewable energy capacity in the Baltic region. The company currently operates approximately 380 MW of renewable energy capacity in Lithuania and is developing an additional 800 MW of projects spanning solar, wind, and energy storage.
Thorvald Spanggaard, Executive Vice President and Head of Project Development at European Energy, highlighted the strategic importance of Lithuania for the company. He noted that alongside new project development, upgrading existing assets and managing the portfolio through partnerships and transactions are essential tools to support the ongoing growth of renewable energy in the Baltic region.
