LG Chem batteries to power German energy storage project

LG Chem will be integrating six large-scale batteries in STEAG power plants.

The STEAG GBS (GroàƒÅ¸batterie-Systeme) plants belonging to the German power supplier in North-Rhine Westphalia and Rhineland Palatinate will be modernized.

With 140 MW hours of power, the energy storage systems will deliver enough energy to supply 10,000 households per day with electricity.

LG Chem’s storage systems are due to be commissioned in STEAG’s power plants in Herne, Làƒ¼nen and Duisburg-Walsum, as well as in Bexbach, Fenne and Weiher starting in the middle of 2016 and running until the beginning of 2017.

The large-scale lithium-ion batteries from the South Korean company have a power capacity of 90 MW, allowing STEAG to rapidly increase its output in the regions mentioned. Integrating the energy storage systems will enable several thousand households to be supplied with energy every day.

This project is a collaborative effort between LG Chem and Nidec ASI, an expert in electrical motors and generators. The ESS storage systems, consisting of batteries from LG Chem and the PCS and EMS solutions from Nidec ASI, are being used by STEAG to generate primary balancing power.

This energy storage capacity is used to offset short-term, unforeseen fluctuations on the grid. The six battery systems will be operated independently of the STEAG power plants. Thanks to the ESS technology, power will be automatically taken off the grid within a few seconds whenever there is an over-supply of energy.

Conversely energy will be fed into the grid to keep the frequency constant at 50 Hz.
