Installation of one of Lithuania’s most important energy projects in terms of national security – the 200 megawatts (MW) battery system – officially commenced at the Vilnius transformer substation. In case of an accident in the power system, these batteries are able to start supplying energy and resume energy supply throughout Lithuania in a matter of seconds.
Minister of Energy Dainius Kreivys said that the project marked a new qualitative level of network resilience and will help Lithuania implement one of the most important tasks before synchronisation – the ability to work in isolated mode, independently.
“The equipment that is now being installed will help ensure the stability and reliability of our power system in the event of disruptions, whether we are operating within the continental European network or independently,” said the minister. “The war in Ukraine has only once again demonstrated the need for full energy independence, so with the beginning of the installation of the batteries, we are witnessing the beginning of another important stage for energy independence. We are prepared for any actions against our power system.”
A total of four 50 megawatt-hours (MWh) batteries will be installed in Lithuania, at the transformer substations in Vilnius, Šiauliai, Alytus District and Utena District.
The project is scheduled to be completed by the end of this year. After synchronisation with the continental European network, this system will contribute to the rapid integration of growing renewable energy sources by storing solar and wind power and returning it to the grid if needed.
