  • Facility is a co-located, utility-scale 16MWh battery energy storage system (BESS) alongside 25 MW of solar PV.
  • BESS will be managed by Flexitricity, leveraging its unique trading arrangement with Axpo to provide full market access for optimisation services.

Axpo Group has signed a long-term route-to-market power purchase agreement (PPA) with British Solar Renewables (BSR) to buy clean energy from its 25 MW solar PV project located at Whaddon Farm, Wiltshire. The site is a co-located, utility-scale 16MWh battery energy storage system (BESS) alongside 25 MW of solar PV.

The ten-year PPA is the first between the power supplier and the power generator that has been closed to date. Located in Whaddon Farm, Wiltshire, BSR’s solar facility will supply Axpo with all of its metered output, allowing Axpo to trade its clean photovoltaic energy on the UK wholesale market. The agreement also supports the UK government’s ambition to improve energy security by accelerating the generation of electricity from renewable sources.

For optimisation of the BESS, BSR has contracted Flexitricity to leverage a bespoke trading arrangement between Axpo and Flexitricity. This partnership facilitates accurate settlement between the boundary meter and the BESS asset meter, ensuring that no value is lost between the solar offtake and dynamic optimisation of the BESS.

Axpo UK Senior Originator Rob Bullyment said: “This agreement with BSR is an important step in the development of our UK business, supporting clients on their sustainability journey. It demonstrates once again Axpo’s willingness and ability to partner with third parties to provide innovative solutions to the energy needs of our clients.”

British Solar Renewables Chief Executive Officer Tim Humpage said: “We are pleased to offer Axpo the opportunity to deliver clean energy solutions to their customers. Their commitment to a decarbonised future closely aligns with our own, and this initiative plays a crucial role in advancing the UK's position as a clean energy leader, supporting the government’s ambitious target of reducing emissions by 81% by 2035.”

Flexitricity Chief Executive Officer Andy Lowe said: “We are delighted to be working with both BSR and Axpo to optimise the BESS at Whaddon Farm. This collaboration is a prime example of how innovative partnerships can contribute to a cleaner, more sustainable energy system, and support the National Energy System Operator’s Clean Power 2030 ambitions.”
