August 5, 2021: Renewable energy firm RES was on August 4 awarded the operations and maintenance contract at Minety, a 100MW/100MWh grid back-up battery in the UK that is being touted as Europe’s largest.
The battery will eventually be even bigger, with planning permission already granted for an extension of 50MW.
Chinese firm China Huaneng Group owns the project and the battery, from Chinese solar and battery firm Sungrow, is housed in two adjacent containers, with 50MW in each. It came online in September 2020 and is fed by wind power.
“Minety is a landmark project for China Huaneng,” said Guo Jingyu, director of the project. “It’s the largest battery storage site deployed in Europe to date, so we’re pleased to be working alongside RES in the operation.”
Since the battery was installed in 2020, regulations in the UK requiring planning permission for battery installations larger than 50MW have been removed.
Minety got around the requirements by installing two separate batteries next to one another.
Shell-owned energy technology firm Limejump also worked with Huaneng on the project.
