Evonik Industries, STEAG, and other project partners put a lithium electricity storage system (LESSY) into operation at STEAG's Fenne power plant in Völklingen, Saarland. The research project is a collaborative venture between Evonik, STEAG Power Saar GmbH, Li-Tec Battery GmbH, Digatron Industrie-Elektronik GmbH, the EWE Next Energy and Power Engineering Saar institutes, and the University of Munster. The large-format energy storage system was developed under a research initiative sponsored by the German Federal Ministry of Education and Research.

LESSY is based on the lithium-ion battery technology that Evonik developed specially for electro mobility. The system is designed to accommodate 4,700 lithium-ion battery cells with a storage capacity of around 700 kilowatt hours and an output of around 1 megawatt.
