Inauguration of One of the World’s Largest BESS Projects


Investment in renewable energy & energy storage in Germany

Nidec ASI and German utility STEAG have inaugurated of one of the world’s largest battery energy storage system (BESS) projects today. Nidec ASI’s six large energy storage systems, with a total capacity of 90MW, are facilitating STEAG in its stabilization of Germany’s power grid.

The official commissioning of the project, attended by Prime Minister Annegret Kramp-Karrenbauer, is taking place in Saarland – one of the six sites where the large energy storage systems have been installed. The BESS systems were officially put into operation at the Weiher power plant in Weiher, Germany earlier this week.

“We are thrilled to partake in today’s inaugural ceremony and see this project come to life,” said Kaila Haines, Marketing Director of Nidec ASI. “The awarding of the major contract speaks to Nidec ASI’s growing leadership in the global energy storage field. We are expanding our services for battery energy storage systems (BESS) to the world’s most prominent industrial companies and today we celebrate a great achievement with STEAG.”

Nidec ASI was commissioned by STEAG in November of 2015 to supply its innovative technology to the power giant as part of its efforts to stabilize Germany’s grid. Breaking ground last May, the multinational industrial solutions leader has provided a massive energy storage system with a total capacity of 90MW,  the largest installment of its kind. The BESS system is based on Nidec ASI’s energy conversion solutions and uses batteries supplied by LG Chem to store electrical energy, which STEAG then uses to provide auxiliary services to the TSO.
