Uniper and NGEN Launch Construction of Major Grid Battery in Germany
Construction has begun on a 50 MW / 100 MWh battery energy storage system in Wilhelmshaven, Germany, developed by Uniper SE and NGEN. The facility is being built on the site of a former coal-fired power plant and is intended to support grid stability by balancing fluctuations from renewable energy sources.
The project aims to store excess electricity from wind and solar generation and release it during periods of higher demand, reducing curtailment and improving system flexibility. Commissioning is planned for the fourth quarter of 2026.
At the groundbreaking ceremony on April 9, regional and company representatives highlighted the role of battery storage in the energy transition. Lower Saxony’s Minister-President Olaf Lies said: “We are currently being starkly reminded of just how important a clean – but above all independent – energy supply is.”
Holger Kreetz, COO of Uniper, stated: “The project exemplifies the next phase of the energy transition: the shift toward an integrated, digitally controlled energy system.”
From NGEN, CEO and Co-Founder Roman Bernard said: “Energy storage is key to making renewable energy more usable, balancing out its volatility, and ensuring security of supply.”
The Wilhelmshaven site is part of the wider ENERGY HUB Port of Wilhelmshaven initiative and reflects ongoing efforts to position the region as a key energy infrastructure hub in Germany.
