The battery system will support Encavis in trading the electric energy generated by German wind and solar parks by primarily balancing out fluctuations in generation and increasing security of supply.
Rolls-Royce will supply and install the energy storage system on a turnkey basis, and the partners said it is expected to go into operation in the first quarter of 2025.
The deal comprises a large-scale mtu EnergyPack QG storage system with a total of 72 battery cabinets and the intelligent mtu EnergetIQ control platform, which Rolls-Royce said 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 a statement, Mario Schirru, CIO/COO of Encavis AG, said: “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 10 years and ensure smooth operation.”
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. 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.
“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 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.”
