UK clean energy developer Harmony Energy has brought online a 98MW/196MWh battery energy storage system (BESS) project.

The site, located in Hull, northern England, uses a Tesla two-hour Megapack system. It was originally planned to go online over two phases in December 2022 and March 2023, the plans however, were accelerated in an effort to support National Grid in providing stability to the UK’s power supply.

Peter Kavanagh, director at Harmony Energy has called the project “the largest of its kind in Europe by energy capacity”.

Autobidder, Tesla’s algorithmic trading platform, will operate the project after continued success managing Harmony’s two existing battery storage projects, Hole Bay and Contego, over the past two years, which were both developed in conjunction with FRV.
