A roundup of battery energy storage system (BESS) news from the UK, with Harmony Energy Income Trust (HEIT) commissioning a system, Field ordering one from Envision and Quinbrook launching construction on another.

Harmony Energy Income Trust powers up 35MW BESS

The Harmony Energy Income Trust fund has announced that its 35MW/70MWh battery energy storage project in North Yorkshire has been successfully energised.

Developed by Harmony Energy, the project’s construction was managed by Tesla with oversight by the Harmony Energy project team. The battery energy storage system (BESS) will be located in Rusholme and is expected to be fully operational in all markets in early August.

Harmony Energy is a developer and investment advisor to the Harmony Energy Income Trust fund.

Envision Energy to supply BESS for 50MWh Field project

Envision Energy has partnered with renewable energy infrastructure firm Field to develop a 50MWh battery energy storage system (BESS) in Blackburn, England.

Envision Energy will supply the Field Whitebirk project with the necessary hardware and equipment to install the BESS onsite. The agreement is part of a long-term partnership aimed at helping Envision’s energy storage division in the UK and Europe.

Mark Walton-Hayfield, senior director for energy storage in the UK and Ireland at Envision Energy, said: “We are proud that our advanced BESS solutions have been recognised by Field for their exceptional standards in safety, reliability and technical capability. We are excited to bring our Tier 1 technology to Whitebirk whilst continuing to collaborate and partner with Field more broadly and make a significant contribution to the global energy transition.”

Construction starts on E.ON and Quinbrook’s 460MWh BESS

Construction is underway on a new battery energy storage system (BESS) project, set to be one of the UK’s largest.

The project, located on the site of a former coal-fired power station in Uskmouth, South Wales, is a collaboration between major international energy firm E.ON and global investment manager Quinbrook Infrastructure Partners.

Building work is being undertaken by local firm Jones Bros Civil Engineering UK, which states that activity is currently focused on developing the foundations for the battery and the power conversion systems (PCS) units, as well as the primary and secondary substations and transformers.

Part of the development plan involves significant ecological enhancement, including the development of a new sustainable energy park and landscaping work to make the area more appealing to wildlife, including otters and water voles.

Construction is expected to be completed by the first quarter of 2025.

Planning permission for 23MW solar project with 57MW battery storage facility

The minister of state, Matthew Pennycook, has granted planning permission for a 23MW solar development with 57MW of battery storage to be installed in Warwickshire.

Set to be operational for 40 years, a revised application was submitted for the solar and storage project by Enso Green Holdings in October 2022. Enso Energy is a renewable energy developer that recently co-developed the first solar and storage project to be connected at a transmission level.

Pennycook, the minister who approved the plans on behalf of the secretary of state, has been vocal in his support of solar development in the UK.

The Warwickshire project, Honiley Road Solar Farm, had been approved by the Warwickshire District Council planning committee in July 2023 but was ‘called in’ by the then-secretary of state for the Department for Levelling Up, Housing and Communities in February this year.
