  • mtu EnergyPack system with 24 megawatt hours to balance out volatile power generation from renewable energies and increase security of supply
  • Commissioning of the storage system based on lithium-ion technology in the first quarter of 2025

Rolls-Royce is supplying an mtu battery energy storage system with an output of 12 megawatts and a storage capacity of 24 megawatt hours to Encavis AG. The battery system will support the Hamburg-based electricity producer in trading the electrical energy generated by German wind and solar parks by, among other things, balancing out fluctuations in generation and increasing security of supply. Rolls-Royce will supply and install the energy storage system on a turnkey basis. It is expected to go into operation in the first quarter of 2025.

Rolls-Royce has also been contracted to provide construction services, installation and 10 years of maintenance
The order comprises a large-scale mtu EnergyPack QG storage system with a total of 72 battery cabinets and the intelligent mtu EnergetIQ control platform, which ensures optimum performance and flexibility. Rolls-Royce has already supported Encavis in the project development for the battery energy storage systems and, in addition to the delivery, is also responsible for the construction work, the complete installation and the provision of all grid connection components for the energy storage system. In addition, there is a long-term value care agreement (VCA) for 10 years, which comes with extensive guarantees: Among other things, the respective capacity value and efficiency of the plant are guaranteed over the entire term.

"We are delighted to have found a reliable partner in Rolls-Royce, who has been at our side since the project development phase and will continue to support us over the next ten years and ensure smooth operation," explained Mario Schirru, CIO/COO of Encavis AG.

The battery energy storage system will be used in an Encavis plant in Hettstedt, Saxony-Anhalt, for a project that was developed with the support of Stadtwerke Hettstedt. There, it is to be charged at times of low electricity prices and provide electrical energy at times of high prices by participating in the day-ahead and intra-day market.

Battery storage contributes to the energy transition and energy security
“The battery storage system, which is now about to be installed, completes our idea of a reliable and innovative energy supply. We are delighted that Encavis AG and Rolls-Royce want to make their contribution to a future-oriented energy infrastructure with us as their partner. In particular, this gives us the opportunity to raise the security of supply of an entire region to a new level,” said Mario Arnold, Managing Director of Stadtwerke Hettstedt GmbH.

“With the large-scale battery storage system, we - together with Encavis AG and Stadtwerke Hettstedt - are making a contribution to the energy transition as well as to grid stabilization. This is because the system ensures that electrical energy from renewable sources is also stored and helps to support the grid when needed. Our battery solutions, which are part of our strategic business areas, make a sustainable and reliable contribution to energy security worldwide,” said Andreas Görtz, President Sustainable Power Solutions at Rolls-Royce Power Systems.
