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 secure the Latvian power grid. In 2025, Latvia, together with the other Baltic states, will synchronize its energy supply system with the continental European power grid.

Following the order, Rolls-Royce will supply a 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 said the press release by the company. The order also includes general contractor services as well as installation and commissioning. The battery system will be used as of fall 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.

Rolands Irklis, Chairman of the Management Board of AST, said, “The battery storage systems are very important for our future energy system. I am delighted that it is being supplied by one of the world’s most renowned manufacturers of energy storage systems.”

The battery system will provide the fast and automatically activated frequency regulation reserves needed for the synchronization mode, where the Baltic power transmission systems operate in sync with the continental European grids. The battery system will provide 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.

Andreas Görtz, President of Sustainable Power Solutions at Rolls-Royce Power Systems, explained, “In addition to battery container solutions, Rolls-Royce supplies these mtu EnergyPack QG large-scale storage solutions, which consist of modular units for capacity and power and can be flexibly configured to any size. We look forward to working with AST and appreciate the trust that the Latvian transmission system operator has placed in us.”
