Rolls-Royce to supply 24MWh BESS to Encavis for German project

May 8, 2024

Rolls-Royce is to supply a 12MW / 24MWh ‘mtu’ battery energy storage system to Encavis AG.

The battery energy storage system will be used in an Encavis plant in Hettstedt in the German state of Saxony-Anhalt, for a project that was developed with the support of Stadtwerke Hettstedt.

“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,” a statement said.

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 and installation, as well as maintenance for a period of ten years.

The order comprises an ‘mtu EnergyPack QG’ storage system with a total of 72 battery cabinets and the ‘intelligent mtu EnergetIQ’ control platform.

Andreas Görtz, president, sustainable power solutions at Rolls-Royce Power Systems, said: “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 stabilisation. 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.”

Mario Schirru, CIO & COO of Encavis AG, added: “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.”
