The Adele – Compressed Air Energy Storage System is a 200,000kW energy storage project located in Stasfurt, Saxony-Anhalt, Germany.

The electro-mechanical energy storage project uses compressed air storage as its storage technology. The project was announced in 2010 and was commissioned in 2013.


The Adele – Compressed Air Energy Storage System is owned by Ed. Zublin (33.33%), a subsidiary of STRABAG , General Electric (33.33%) and RWE (33.33%).

The key applications of the project are electric supply capacity and electric energy time shift.

Contractors involved

Ed. ZUBLIN , General Electric and RWE have delivered the energy storage project.

Additional information

The plant became operational in 2013; it will have a storage capacity of one billion watt-hours (GWh) and generate electrical power of up to 200 MW. That way ADELE will be able to provide backup capacity within a very short time and replace forty state-of-the-art wind turbines for a period of five hours. The German Federal Ministry of Economics is willing to offer state funding, which underlines the special importance of this project. Altogether, the project members will contribute an amount of EUR 10 million.
