The Government’s resolutions were just approved by the Cabinet of Ministers of Lithuania: electricity storages will be used to ensure uninterrupted operation of the power system.
In this project, four electricity storage facilities of 50 megawatt-hours (MWh) each will be installed to make sure that the instantaneous reliability of the operation of the energy transmission system is safe and guaranteed in the event of unforeseen situations in the grid. The operation of the facilities is being performed by the IPS/UPS power system: in case of need, they will start supplying energy immediately and will stop as soon as the balance is restored in the system. It is a great step forward because the already existing, current facilities are not capable of responding immediately and take longer to start up.
Besides the mentioned resolutions, the Lithuanian Parliament has already passed another electricity storage project that provides the installation of 200 megawatts (MW) to increase the instantaneous reserve – these facilities are predicted to serve from 2022.
“In strengthening energy security and independence, we must ensure the uninterrupted, reliable and stable operation of the power system,” said Dainius Kreivys, Minister of Energy. “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.”
As this project bears with outstanding importance, according to the resolutions, the electricity storage facility system operator, who is responsible for the installation, operation, maintenance and management of the electricity storage facility system, will be added to the list of enterprises of importance to ensuring national security. Also, the electricity storage facility system itself is going to appear on the list of infrastructure critical to ensuring national security, so these facilities will enjoy protection from all risk factors that could threaten national security interests.
As energy security is an essential part of national security, these facilities are aimed to ensure reliable, stable and consumer-oriented operation, until the Lithuanian electricity system will be connected to the continental European network.
