Since gaining independence from the Soviet Union in 1990, Lithuania has made steady progress toward economic growth and energy independence. The country''s current rate of imported electricity is 55%, with electricity demand at 2.1 GW peak and 12.6 TWh annually. Lithuania closed the Ignalina Nuclear Power Plant in 2009 and currently operates synchronously with the Russia-Belarus power system, though a de-synch is planned in early 2025.
Results from this study will help the Lithuanian Energy Agency understand and plan for issues related to feasibility, reliability, public health, and equitable local economic development. It will also empower Lithuania to harness domestic energy resources and accelerate its journey to energy independence.
This agreement spans 4 years, from 2023 to 2027, but most of the study will be completed and published by the end of the second year. The remaining 2 years will leverage direct support from technical experts at NREL to drive capacity building, training, and implementation. The following scoping questions will be kept in mind throughout the study:
Construction began on the four projects connected to substations in Šiauliai, Alytus, Utena and Vilnius in June last year, as reported by Energy-Storage.news. They will enable the country''s electricity grid to run in islanded mode as well as synchronise with the EU grid as Lithuania seeks to disconnect from the Russian energy system, a move which pre-dates the latter’s invasion of Ukraine in early 2022.
Initial tests of the battery cells, transformers and other electrical equipment were carried out last month and further testing and commissioning will take place for a full launch and connection to the power grid by the end of spring. The projects are being developed by state-owned energy sector holding company EPSO-G through a special purpose company Energy Cells.
The projects are set to begin operation in sequence rather than all at the same time, and will provide ‘Isolated Electric Power System Operating Reserve Service’, EPSO-G said. The company first announced the projects back in December 2021.
The four battery storage projects will total €109 million of investment (US$116 million) and are being majority-funded (c.80%) by the EU''s Recovery and Resilience Facility (RRF) NextGenerationEU plan called New Generation Lithuania. The bloc-wide framework has seen money go to energy storage projects in Finland and Greece too.
Fluence, the largest battery storage system integrator globally, won the contract to design, manufacture and connect the battery energy storage projects to the transmission system and provide maintenance services for 15 years thereafter, in partnership with its parent company Siemens.
Energy-Storage.news'' publisher Solar Media will host the eighth annual Energy Storage Summit EU in London, 22-23 February 2023. This year it is moving to a larger venue, bringing together Europe''s leading investors, policymakers, developers, utilities, energy buyers and service providers all in one place.

Initial tests of the installed battery cells, transformers and other electrical equipment were carried out at battery parks in Vilnius, Šiauliai, Alytus and Utena, acoustic walls were installed and the environment was tidied. By the time the planned battery parks are operational, the system control centre will be completed, the parks will be connected through the transmission network, final system testing will be carried out and construction documentation will be in place.
The battery parks are planned to start operating one after the other – once the first park is operational, the system will provide an instantaneous reserve service of 50 megawatts (MW) and once the other three parks are operational, it will operate at its full planned capacity of 200 MW.
During the tests, the capabilities of the system before and after synchronisation with continental European networks are tested. Interoperability with the transmission system operator''s network is tested, as well as special tests related to isolated operation scenarios. The battery park system is the first project of its type and importance in our region to use the knowledge gained from Litgrid''s 1 MW battery pilot project.
The battery energy storage system will be able to deliver power to the network in less than one second, providing instantaneous power reserve and the ability to operate in isolated mode. The system consists of four battery parks in Vilnius, Šiauliai, Alytus and Utena, with 312 battery cells – 78 in each. The Energy Cells battery energy storage system, which will be integrated into the Lithuanian network, will have a total combined capacity of 200 MW and 200 MWh.

After the tests are complete, the battery park system will be fully integrated into the country''s electricity transmission network, increasing the stability and reliability of the Lithuanian electric power system. This will be Lithuania’s first battery park system and one of the biggest in Europe.
"Not only will the batteries increase the reliability of the system – but they will also enable us to disconnect from the BRELL ring and synchronise with the continental European network ahead of schedule, in 2024," said Minister Kreivys.
The system of battery storage facilities, designed to ensure the instantaneous energy reserve for Lithuania, will comprise four battery farms in Vilnius, Šiauliai, Alytus and Utena with 312 battery cubes – 78 in each farm. The total combined capacity of the energy storage system is to be integrated into the Lithuanian grid by Energy Cells. Along with specially made transformers and other equipment, all 312 battery cells have already been installed and connected in the battery parks at the transformer substations.
If an accident occurs in the power system, this battery system will be able to start supplying energy and resume energy supply throughout Lithuania in a matter of seconds – this is its key function until synchronisation with the continental European network (CEN). In the event of disruptions in the power grid, energy from the battery parks can be automatically transferred to the grid within one second and supplied until the secondary reserve – the Kruonis hydroelectric power plant – is connected.
