Uniper is planning to build a battery storage system at the Heyden power plant site in Petershagen together with NGEN, a leading provider of energy solutions. The battery storage system with a capacity of 50 MW/100 MWh is expected to go into operation in 2025.

The partnership between Uniper and NGEN emphasizes the joint commitment to innovation and sustainability as well as the commitment to the expansion of renewable energy infrastructure in Germany. Energy storage systems enable more efficient utilization of all generation plants that feed electricity into the local grid because power can be stored and used when needed. They facilitate the integration of renewable energy sources by balancing the intermittent nature of renewables, and ensuring a reliable, flexible power supply. By doing so, they also help to improve grid stability.

“We are delighted to be realising this project with NGEN. Energy storage plays an important role in the development of the green growth business in Uniper's strategy. By using cutting-edge technology and expertise to develop sustainable solutions, we will play a central role in shaping the future of energy in Germany."

Jan Taschenberger, COO New Green Power & Gas, Uniper SE

„As part of the collaboration on this project, NGEN will open its first office in Germany in Frankfurt a. M. to further consolidate its presence in the European energy market and emphasize its commitment to supporting the energy transition in Germany."

“We are very excited to partner with Uniper on the battery storage project in Petershagen and to open our first office in Germany. This strategic collaboration will enable us to drive innovation, accelerate the deployment of renewable energy, and contribute to a more resilient and sustainable energy system in Germany. The project represents a significant step forward in our commitment to enhancing energy storage solutions and demonstrates our dedication to supporting Germany's energy transition goals."

Roman Bernard, CEO of NGEN GROUP

„The battery storage system will consist of 26 energy storage packs. A battery energy storage unit is 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."
