Electricity storage facilities recognised as critical to ensuring national security


2021 04 29


The Cabinet of Ministers has approved the Government’s resolutions which include the batteries that will ensure uninterrupted operation of the power system until synchronisation is complete in the list of synchronisation projects, and also add to the synchronisation actions and measures plan, which details the actions and measures for the installation of the electricity storage facility system and provides specific time frames.

“In strengthening energy security and independence, we must ensure the uninterrupted, reliable and stable operation of the power system. Today, we have provided for crucial technical details on how we will ensure uninterrupted power supply until the end of the synchronisation project. The next step is the installation of these batteries,” says Minister of Energy Dainius Kreivys.

The resolutions also provide that the electricity storage facility system operator responsible for the installation, operation, maintenance and management of the electricity storage facility system will be included in the list of enterprises of importance to ensuring national security. Likewise, the electricity storage facility system will be included in the list of infrastructure critical to ensuring national security. This means that these facilities will be ensured protection from all risks factors that could threaten national security interests.

We would like to remind you that the Seimas has already approved a project that provides for the installation of 200 MW of storage facilities in Lithuania to increase the instantaneous reserve. Lithuania plans to have these batteries as early as next year.

The existing facilities are not capable of responding immediately and take longer to start up, so the country will need to be equipped with batteries that can start supplying power within seconds of a disruption occurring.

A total of four 50 MWh electricity storage facilities will be installed in Lithuania. They will be used to ensure the instantaneous reliability of the operation of the energy transmission system in the event of unforeseen situations in the grid. The energy storage facilities will start supplying energy immediately and will stop as soon as balance is restored in the system in the usual ways. This function is currently being performed by the IPS/UPS power system.

The electricity storage facility project is based on the interests of national security – the energy storage system is necessary to ensure reliable, stable and consumer-oriented operation of the Lithuanian electricity system before and after synchronisation with the continental European network.
