About the project
Energy Cells installed and integrated a system of four energy storage batterie parks with a total capacity of 200 megawatts (MW) and 200 megawatt-hours (MWh) into Lithuania’s energy system.
Energy Cells installed four 50 MW and 50 MWh energy storage battery parks at transformer substations in Vilnius, Šiauliai, Alytus, and Utena. It is currently the largest project in the Baltics and one of the largest of its kind in Europe.
Lithuania’s battery energy storage system vital to ensure the security of Lithuania’s energy system and the possibility to operate in an isolated mode. The energy storage system, which ensures the operation of the instantaneous isolated mode reserve for Lithuania, after finishing synchronisation with the continental European networks (CEN) program, will be used for the integration of energy produced from renewable energy sources after the synchronisation.
The consortium of Siemens Energy and Fluence installed and now provides warranty service of the high-capacity energy storage system.
On the basis of Joint Activity, the companies implemented the project after they won an international public tender for the purchase of system installation services and energy storage technologies.

Q4 2023
Start of providing the services of ensuring the operation in the isolated mode electricity reserve with 200 MW
Energy security
As Lithuania prepares to join the continental European networks (CEN) in 2025 and disconnect from the BRELL ring (Belarus, Russia, Estonia, Latvia and Lithuania), it is important to ensure the operation of the instantaneous electricity reserve and the possibility to operate in isolated mode.
The instantaneous electricity reserve of isolated mode for Lithuania will be ensured by the electricity storage facilities system with the 200 megawatts (MW) and 200 megawatt-hours (MWh) capacity. If needed, the high-capacity reserve storage facilities will start supplying power immediately – within 1 second. This will ensure a reliable supply of active power to the electricity grid until other sources of electricity generation are commenced. Currently, Lithuania’s power plants operating in the IPS/UPS system can start supplying power within 15 minutes.
The energy storage facilities system operator Energy Cells is obliged to provide the services ensuring the operation of the isolated mode electricity system reserve to Lithuania prior to the synchronisation with the continental European networks. Later, energy storage facilities will contribute to the integration of renewable energy.
Consultancy services
According to the available practical experience in the fields of design, installation, testing, integration, operation and remote monitoring, we are providing consultancy services on development of projects of energy storage systems in Lithuania and Europe.
Our purpose is to ensure that the projects of battery energy storage systems (hereinafter referred as BESS) are technically precise, safe, effective and could be implemented without expensive mistakes.
