• In December 2024, Neoen started construction of the Arneburg Battery in Saxony-Anhalt
• With a capacity of 45 MW / 90 MWh, the battery is expected to be fully operational as of 2026 and will actively support the German electric grid, improving both its stability and resilience
• Arneburg is Neoen’s first project to get off the ground in Germany, where the company has strong growth ambitions, backed by a robust pipeline of projects exceeding 1 GW, at various stages of development
• Neoen leverages its extensive expertise in developing and operating large-scale batteries to expand into the German market

Neoen, one of the world’s leading producers of exclusively renewable energy and a major battery storage operator, has given storage solution supplier Nidec full notice to proceed in December 2024, signaling the start of construction of the Arneburg Battery, Neoen’s first asset in Germany.

With a capacity of 45 MW / 90 MWh, Arneburg Battery will be located near Arneburg, Saxony-Anhalt. The battery is set to be operational in 2026. In line with its model, Neoen owns 100% of Arneburg Battery and will be the operator of the energy storage facility.

Arneburg Battery will provide the grid with both intraday power trading and balancing services. It will help to maintain real-time balance between production and consumption, hence enhancing power system stability and facilitating the integration of renewable energy assets. As Germany is already fully engaged in its energy transition, batteries like Arneburg will play a key role in strengthening the grid while providing flexibility.

Neoen’s strategy is to leverage its extensive expertise in developing and operating large-scale batteries to expand into Germany, building on its success in multiple other markets. Since 2017, Neoen has been a global pioneer in the field of battery storage and is a world-leading developer, owner and operator of batteries. Its global storage portfolio in operation or under construction currently sits at 2,3 GW / 5,3 GWh. This includes some of the largest batteries in the world, such as the 270 MW / 540 MWh Western Downs Battery or the 560 MW / 2,240 MWh Collie Battery in Australia, as well as several batteries in Europe, including Isbillen Power Reserve (93.9 MW / 93.9 MWh) in Sweden and Yllikkälä Power Reserve One and Two (86.4 MW / 142.9 MWh together) in Finland, which are the largest in the Nordics.

This first investment in storage in the country aligns with Neoen’s ambition to establish itself as a key player in Germany’s battery sector. Since establishing its presence in Karlsruhe in 2023, Neoen has been actively developing multiple storage projects nationwide and has already built up a portfolio of projects exceeding 1 GW.

Andrés Marx, Managing Director of Neoen Germany, said: 
“Starting construction of the Arneburg Battery is a major step in our commitment to supporting Germany’s shift toward clean, reliable energy solutions. We are particularly grateful for the support from the county, municipality and grid operator of Arneburg in getting this project off the ground. Arneburg is paving the way for Neoen’s future in Germany, where we have high ambitions and multiple projects under development”.

Xavier Barbaro, Neoen’s Chairman and Chief Executive Officer, concluded: 
“The launch of the Arneburg Battery, only two years after establishing our presence in the country, is a major milestone and I thank the Neoen team in Germany for this great achievement. Batteries play an increasingly pivotal role in integrating more renewable energy into the grid, while boosting its stability and resilience. As a leader in storage, we are excited to bring our deep expertise to serve the energy transition, in Germany and around the world.”
