Where is RWE building the largest battery storage system in Germany?

Spread across two locations and coupled with hydropower stations – RWE is building one of the largest and most innovative battery storage systems in Germany. A battery system with a total capacity of 117 megawatts is being installed at the company’s power plants in Lingen (Lower Saxony) and Werne (North Rhine-Westphalia).

Why is energy storage important in Germany?

Balancing the rising share of intermittent renewables calls for new solutions and business models. In Germany, energy storage has experienced a dynamic market environment in recent years, particularly for providing ancillary services, and in home applications. This report sheds light on the important topic of energy storage.

Do battery storage systems need a permit in Germany?

In Germany, in most cases, neither environmental nor energy industry permits are required for battery storage system alone, though it must comply with the regulation on electromagnetic fields (26. BImSchV). Battery storage systems must be registered in the market master database (Marktstammdatenregister).

Will demand for power storage increase in Germany?

Given these market forces and the increasing extension of the Energiewende into mobility and heating, German energy industry experts surveyed by the Centre for European Economic Research (ZEW) expect demand for power storage to increase substantially in the years to come.

How do storage systems work in Germany?

Can pumped hydro storage be a key component of Germany's electricity system?

The study by Keles and Yilmaz , for instance, considers only the option of pumped hydro storage (PHS), as it is already a key component of the German electricity system. Others consider multiple technology options, with Bartholdsen et al. , for instance, considering also lithium-ion batteries and hydrogen storage (via power-to-gas).
