Europe’s biggest battery storage system in megawatt-hour (MWh) terms earned £2.3 million (US$2.85 million) revenues during its first full quarter in commercial operation.
UK-based investment fund Harmony Energy Income Trust said recently that its Pillswood Battery Energy Storage System (Pillswood BESS) in northern England was one of the best-performing battery storage assets in Britain in the first quarter of 2023.
Chinese multinational corporation Envision Energy has agreed on a partnership with Harmony Energy Income Trust to provide battery energy storage systems (BESS) for projects in the UK.
Envision Energy will develop liquid-cooled energy storage systems which are capable of providing energy time-shifting, capacity services and frequency regulation services.
Harmony Energy Income Trust invests within the battery energy storage sector and currently operates 109MW/218MWh of BESS in the UK with a further 286.4MW/572.8MWh under construction.
Wormald Green and Hawthorn Pit, the BESS projects Envision is contracted for, are set to commence in Q2 2023, both anticipated to be fully completed and connected to the grid in Q1 2024. Wormald Green has a storage capacity of 33MW/66MWh whereas Hawthorn Pit has a slightly higher storage capacity of 49.9MW/99.8Mh.
According to Envision, its expertise lies in full-stack technical capabilities ranging from battery technologies to energy storage systems. This has also seen it support the deliverance of two-hour duration BESS.
This could strengthen Harmony Energy’s vision with the company also exploring two-hour duration BESS projects. As of the end of the first year since the company’s incorporation, it had six two-hour duration BESS projects totalling 312.5MW/625MWh.
