The 49MW/98MWh Jamesfield standalone battery energy storage system (BESS), a joint venture between TagEnergy and Harmony Energy, has gone live in Scotland.

The project, located near Abernethy, Scotland, uses 2-hour duration Tesla Megapack lithium-ion batteries and Tesla’s Autobidder AI software.

Jamesfield became a joint venture with energy infrastructure developer Harmony Energy following the clean energy enterprise’s acquisition of a 60% stake in the project in November 2021.

Following £12.5 million in funding from Santander UK’s green energy initiative, the project progressively came online from November 2023 before being completed and fully energised in early February 2024.  

“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,” said Peter Kavanagh, chief executive at Harmony Energy.

“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.” 

TagEnergy’s chief executive officer Franck Woitiez added: “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.”
