Rolls-Royce has secured its largest-ever battery energy storage order, with Lithuanian energy supplier Ignitis Group selecting its mtu EnergyPack systems to support national grid stability and renewable integration.
The project includes a total storage capacity of 582MWh and an output of 291MW, with installations planned across three strategic sites: Kelmė and Mažeikiai wind farms, and the Kruonis pumped storage power plant. The systems will begin contributing to Lithuania’s grid from 2027.
“An important component of the Rolls-Royce solution is the mtu EnergetIQ Manager, which was developed in-house and is tailored to our battery systems. This intelligent control system not only manages the three battery parks, but also the connected wind farms and controls both power supply and storage,” said Andreas Görtz, president of Sustainable and Mobile Power Solutions at Rolls-Royce Power Systems.
The company has now delivered over 200 mtu battery projects worldwide.
