The electricity storage project will guarantee security and stability of energy supply in Lithuania. It will also enable Lithuania to disconnect from the Russian controlled electricity grid and synchronize with the continental European electricity grid.
The Government of the Republic of Lithuania appointed Energy cells as the operator of the storage facilities that will provide Lithuania with an instantaneous electricity reserve. Energy cells signed a contract with the winning Siemens Energy and Fluence consortium. Energy storage facilities system design works were started.
The energy storage system, which will provide Lithuania with an instantaneous isolated operation electricity reserve until synchronisation with the continental European networks (CEN), will be used after synchronisation for the integration of energy produced from renewable sources.
The Energy Cells storage facility system to be integrated into the Lithuanian grid will have a total combined capacity of 200 megawatts (MW) and 200 megawatt-hours (MWh).
It will also enable Lithuania to disconnect from the Russian controlled electricity grid and synchronize with the continental European electricity grid. In case of accidents, batteries will provide instantaneous electricity reserve service in less than one second. In the future, batteries will help to integrate renewable energy sources.
Lithuanian power plants currently operating in the IPS/UPS system can start supplying power within 15 minutes. Once synchronised with the CEN system, the energy storage facilities will be able to store electricity generated by solar or wind power plants and feed it into the grid when needed.
