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 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.
In July of 2021, the Government of the Republic of Lithuania appointed Energy cells as the operator of the storage facilities for the provision of electricity from the instantaneous isolated mode reserve and entrusted it with the operation of the system of electricity storage facilities.
The instantaneous electricity reserve of isolated mode for Lithuania will be ensured by theelectricity 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.
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.
