The "Energy Cells" is a project that consists of a system of four energy storage devices (batteries) with a total capacity of 200 megawatts (MW) and 200 megawatt-hours (MWh) into Lithuania’s energy system. Energy Cells has four 50 MW and 50 MWh energy storage facilities at transformer substations in Vilnius, Šiauliai, Alytus, and Utena. It is currently the largest project in the Baltics and one of the largest of its kind in Europe. Energy Cells received 87.6 million euros from the NextGenerationEU, the Recovery and Resilience Facility under the “New Generation Lithuania” plan for the installation of the energy storage system. The total value of the project, which will provide Lithuania with the instantaneous power reserve and the possibility to operate autonomously in isolated mode, is of 109 million euros.
