Rolls-Royce has received an order from the Latvian transmission system operator Augstsprieguma tikls (AST) to supply an mtu large-scale battery storage system to help secure the stability of the Latvian power grid.
In 2025, Latvia, together with the other Baltic states, will synchronise its energy supply system with the continental European power grid. Dr Jörg Stratmann, CEO of Rolls-Royce Power Systems commented: "Our battery solutions, which belong to our strategic business fields, make a sustainable and reliable contribution to energy security worldwide. The facility for Latvia will be our largest battery storage system to date.”
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 used as of autumn 2025 at two locations – a 20 MW/40 MWh battery storage at the AST substation in Tume and a 60 MW/120 MWh battery storage at the AST substation in Rezekne. The battery system, described by its maker as ‘state-of-the-art’ will provide the fast and automatically activated frequency regulation reserves needed for the synchronisation mode. The battery system, says R–R will provide the power reserves at significantly lower costs than the existing conventional power plants. Rolls-Royce and AST have signed a 5-year long-term service agreement for the system.
