RES has won a tender to provide O&M services for China Huaneng Group’s Minety battery storage project, which began trading last month.

Lauded as the largest battery storage development in Europe to date, the project consists of two 50MW batteries developed by Penso Power and funded by China Huaneng Group and CNIC Corporation.

It recently secured planning permission to extend the project by a further 50MW.

Minety is to be supported by RES’ technicians, who will oversee the preventative maintenance and monitor the project 24/7/365 from the company’s global Control Centre.

"RES have demonstrated their knowledge and experience of operating battery storage projects and we're looking forward to optimising the value of this project with our new partners," Jingyu Guo, director of the Minety project from China Huaneng Group, said.

RES currently operates in ten countries across the world, having delivered over 21GW of renewable energy projects in its 39-year history.

In early 2020, Shell Energy Europe signed a multiyear offtake agreement for the Minety site, located 12 miles away from Swindon, with its subsidiary Limejump optimising the battery energy storage system, trading power from Minety into a number of services including National Grid ESO’s Dynamic Containment.
