Nidec ASI joins German utility to install one of world’s largest BESS

Published on: December 2, 2016 8:14 amBy: ESJ

Italian generating firm Nidec ASI and German utility STEAG have installed one of the world’s largest battery energy storage systems with a total capacity of 90MW across six different sites in Germany.

LG Chem, the Korean electronics giant, supplied the batteries for the BESS, which was installed at three sites in North Rhine Westphalia, in Germany’s northwest, and three in Saarland, in the south.

The systems, based on Nidec ASI’s energy conversion solutions, store power which STEAG then uses to provide auxiliary services to Germany’s power grid. Media reports suggest the project cost around $100 million.

Each of the six 15MW systems contains five 3MW units, which include power converters, transformers, the control system and the LG Chem new-generation lithium batteries.

Developing energy storage technologies has become a prime focus in Germany as part of its transition away from nuclear and fossil fuels to renewable energy sources.

Between 2012 and 2015, 26MW in 10 pilot projects was installed, much of which received funding from the Federal Ministry for Economic Affairs and Energy, according to the organization GTAI – Germany Trade & Invest.

This latest STEAG installment increases the country’s grid battery storage capacity by more than three times as part of Germany’s ‘ambitious energy transition project’, says GTAI.

“The planned closure of all nuclear power plants in Germany by 2022 poses a significant technological challenge in the transport and storage of electricity from multiple sources,” said Giovanni Barra, CEO of Nidec ASI.

“Nidec ASI provides the technological innovation of its management system and storage control, which allows the release of electricity to the grid within milliseconds to strengthen its stability, and also offers experience in managing such complex projects.”

Nidec ASI was formerly known as Ansaldo Sistemi Industriali.
