The primary activity of Energy Cells an electricity storage system operator, is to ensure the provision of operating reserve services for the isolated power system to the transmission system operator Litgrid. Energy Cells has been providing this service at its full planned capacity of 200 MW since October 2023.
The energy storage system operated by Energy Cells consists of four identical battery parks, each with a capacity of 50 MW and 50 MWh, located in Vilnius, Šiauliai, and the Alytus and Utena districts. The operation of the four battery parks is monitored continuously (24 hours a day, 7 days a week) from a control center in Vilnius. In the event of disturbances in the transmission system grid, the energy storage system’s equipment can automatically respond within 1 second to the transmission system operator Litgrid’s need to ensure the security and stability of the power system, and within 1 second supply power to the grid or draw power from the grid, thereby helping to regulate the frequency of the transmission grid. Once the instantaneous energy reserve service is activated, it would be provided until the facilities of other market participants capable of providing the service come online.
