The company Energy cells that has to assure instantaneous energy reserve for Lithuania presented the project of the energy storage facilities system to the representatives of Alytus regional municipality and communities. The energy storage facilities system will assure stability and reliability of the Lithuanian energy system until synchronisation with the networks of continental Europe and capacity to work independently in the isolated regime, in case of disturbances. After the synchronisation with the networks of continental Europe in 2025, the energy storage facilities system will be used to integrate solar and wind energy into the domestic energy system.
The energy storage facilities system of total power of 200 Megawatts (MW) and capacity of 200 Megawatt Hours (MWh) will consist of four 50 MW battery parks, one of which will be built in Litgrid substation located in Butkunai village, Alytus region. The operator of storage facilities, Energy cells, is going to erect other three parts of the system in Vilnius, Siauliai, and Utena. The company is going to start providing the service of assurance of instantaneous isolated operation reserve of electricity system to the Lithuanian transmission system operator this December, and the works in Litgrid substation will be started in June.
“If necessary, these batteries would start supplying energy to the network immediately until other energy production sources are turned on, for example, Kruonis Hydroelectric Power Plant. The latest and most advance technology of the 6th generation of the batteries of manufacturer Fluence was installed in the energy storage facilities system. It allows resuming electricity supply in 1 second only,” – said CEO of Energy cells, Mr. Rimvydas Stilinis.
The energy storage facilities are designed, will be made and connected to electricity transmission system by the consortium of leaders in the technological field – companies Siemens Energy and Fluence. The companies operating on the basis of joint venture have won the international competition for procurement of energy storage technologies and services of system installation announced by Energy cells. The contract of the value of 109 million euro was signed with them. According to this contract, the companies are going to provide the warrantied servicing and maintenance services for 15 years after having launched the system.
This project is among the key projects related to synchronisation of the Lithuanian and Baltic energy networks with continental Europe. Moreover, it is the first project of such scope in Lithuania, with regard to which financing was approved under the EU Recovery and Resilience Facility (RRF) and the first project, the implementation of which with the help of this facility has been started.
