Germany-based Rolls-Royce has been awarded a contract to supply two large-scale battery vitality storage strategies to Augstsprieguma tikes (AST), Latvia’s transmission system operator, with a cumulative output of 80 MW and a storage functionality of 160 MWh.

The company’s mtu EnergyPack QG large-scale battery storage strategies, that are based mostly totally on the nickel-manganese-cobalt (NMC) battery chemistry, shall be used at two locations from autumn 2025 onwards. A 20 MW/40 MWh system shall be put in on the AST substation in Tume in west Latvia and a 60 MW/120 MWh battery storage on the AST substation in Rezekne throughout the east. 

The facilities will current the fast and mechanically activated frequency regulation reserves needed for synchronization with the European grid.
