The 49MW/98MWh standalone project near Abernethy progressively came online from November 2023 as sections of the site were finalised, and became fully energised when construction was completed in early February 2024.

The Jamesfield BESS utilises 2-hour duration Tesla Megapack lithium-ion batteries, together with Tesla’s Autobidder AI software for real-time trading and control.

Independent renewable energy company RES is asset manager.

TagEnergy chief executive officer Franck Woitiez said energisation of TagEnergy’s third battery energy storage facility in the UK was testament to the momentum it has built in the UK as it speeds the energy transition.

“This is another important marker for TagEnergy in the UK and beyond as we leverage our substantial storage expertise to help stabilise the grid and make a meaningful difference to the planet by relentlessly pursuing a renewables-led energy future,” Mr Woitiez said.

“We are proud to have delivered another vital project, this time with our valued partner Harmony Energy, that will enable more people to connect to more competitive renewable power.

“Our three completed projects, together with the more than 200MW of BESS under construction in the UK, is testament both to our commitment and the success of our
approach. We look forward to bringing more projects online as we focus on helping the UK move closer towards net zero carbon emissions.”

Harmony Energy chief executive officer Peter Kavanagh said: “The completion of the Jamesfield BESS is another significant milestone for our valued partnership with TagEnergy, following the success of our other joint venture site, Chapel Farm.

“Battery energy storage systems are vital for unlocking the full potential of renewable energy in the UK. They play a pivotal role in advancing the Net Zero transition through the reduction of Co2 emissions, and are crucial for securing the future stability of the UK’s energy supply and reducing dependence on foreign gas imports.”

The Jamesfield development became a joint venture with Harmony Energy, following TagEnergy’s acquisition of a 60% stake in the project in November 2021. Santander UK supported the green energy initiative with £12.5m funding.

It was TagEnergy’s third investment in battery storage facilities in the UK to become operational, after Hawkers Hill Energy Park and Chapel Farm.

Those projects, together with other projects under construction, take TagEnergy’s secured portfolio in the UK to date to 320MW/640MWh.
