Project Approval

Uniper has received approval to construct and operate a 50-megawatt battery storage facility at the former Wilhelmshaven power plant site. This development supports the site's transformation and contributes to the regional energy transition.

Energy Storage Benefits

The new battery storage system will enhance flexibility and reliability in power supply. It plays a crucial role in integrating renewable energy sources by balancing fluctuations and strengthening grid stability.

Site Developments

The Wilhelmshaven power plant was shut down in December 2021. Since then, Uniper has pursued new projects at the site, including a photovoltaic plant on the former ash landfill. The solar power plant, with a planned annual output of 17,500 megawatt hours, is under construction and scheduled for commissioning in July 2026.

ENERGY HUB Wilhelmshaven

ENERGY HUB Wilhelmshaven, with over 40 national and international members, focuses on renewable energies, hydrogen, and carbon management. The location aims to become a central hub for supply security, supported by politics, business, and science. Uniper's battery storage facility is part of this transformation initiative for the city on the North Sea coast.
