Rolls-Royce to supply 12MW/24MWh battery storage to Encavis AG

Rolls-Royce on Tuesday (May 7) announced that it will supply large-scale battery storage for grid stabilization and electricity trading to Hamburg-based electricity producer, Encavis AG.

As part of the contracted order, Rolls-Royce will supply a mtu battery energy storage system with an output of 12 megawatts and a storage capacity of 24 megawatt-hours to Encavis Additionally, Rolls-Royce will provide construction and installation with 10 years of maintenance.

"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," said Andreas Görtz, President of Sustainable Power Solutions at Rolls-Royce Power Systems.

"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."

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, for ensuring optimum performance and flexibility.

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. The system will 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.

"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.

The battery energy storage system based on lithium-ion technology is expected to be commissioned in the first quarter of 2025 and will help balance the volatile power generation from renewable energy and provide a reliable energy supply.

"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," commented Mario Schirru, CIO/COO of Encavis AG.
