TagEnergy and Harmony Energy announced this week the activation of their Jamesfield battery energy storage system (BESS) near Abernethy, Scotland.

The 49MW/98MWh project, leveraging Tesla Megapack lithium-ion batteries and Tesla’s Autobidder AI software, was progressively brought online from November 2023 and reached full operational status in early February 2024.

The Jamesfield BESS, managed by renewable energy company RES, marks a significant advancement in the UK’s transition towards net zero emissions.

“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 Harmony Energy Chief Executive Officer Peter Kavanagh.

“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,” said Kavanagh.

Franck Woitiez, CEO of TagEnergy, reflected on the project’s significance, noting it as TagEnergy’s third battery energy storage facility in the UK and a milestone in the company’s efforts to facilitate the energy transition.

The project, which became a joint venture following TagEnergy’s acquisition of a 60% stake in November 2021, received £12.5m in funding from Santander UK. It represents the second operational JV in battery storage facilities between TagEnergy and Harmony Energy in the UK, following Chapel Farm.

With the activation of Jamesfield, Harmony Energy now oversees an operational portfolio exceeding 500MW / 1GWh.
