Rolls-Royce will supply an mtu EnergyPack QG large-scale battery storage system with an output of 80 MW and a storage capacity of 160 MWh. This makes the system one of the largest battery storage systems in the EU. The order also includes general contractor services as well as installation and commissioning. The battery system will be deployed at two locations from fall 2025 - a 20 MW/40 MWh battery storage system at the AST substation in Tume and a 60 MW/120 MWh battery storage system at the AST substation in Rezekne.
Power reserves with lower costs than exististing conventional plants
The state-of-the-art battery system will provide the fast and automatically activated frequency regulation reserves needed for the synchronization mode in which the Baltic power transmission systems operate in sync with the continental European grids. The battery system will provide the power reserves at a significantly lower cost than the existing conventional power plants. Rolls-Royce and AST have signed a 5-year contract for the maintenance of the system and an availability guarantee.
