Enerheads has signed a cooperation agreement with Arvilsa, UAB to optimize a 43 MW stand-alone Battery Energy Storage System (BESS) in Tauragė, Lithuania. Scheduled to begin operations in 2026, the project will include an 86 MWh storage capacity with a two-hour duration.

Arvilsa is responsible for developing the facility, while Enerheads will provide optimization and trading services. The BESS will participate in energy and balancing markets, including FCR, aFRR, mFRR, as well as day-ahead and intraday trading.

This partnership marks an important step in strengthening Lithuania’s grid flexibility and supporting the integration of renewable energy. The project is also aligned with the Baltic region’s rapidly expanding balancing markets, where storage is expected to play a key role in ensuring stability and efficient energy use.
