Uniper, together with NGEN, a prominent provider of energy solutions, is planning to build a battery storage system at its Heyden power plant site in Petershagen North Rhine-Westphalia, Germany. The system, with a capacity of 50 MW/100 MWh, is expected to go into operation in 2025.  Heyden is an 875 MW coal fired plant due to be retired permanently in September this year.

As part of the collaboration on this project, NGEN will open its first office in Germany in Frankfurt am Main, to further consolidate its presence in the European energy market and emphasise its commitment to supporting the energy transition in Germany.

The battery storage system will consist of 26 energy storage packs, each of the units a fully integrated system that converts energy for storage in rechargeable lithium battery modules. The storage unit contains battery modules with integrated inverter modules, a thermal system for cooling or heating the components, and an interface for operating the system.
