Clean energy firm TagEnergy and renewable infrastructure developer Harmony Energy’s Jamesfield battery energy storage system (BESS) has gone live today, following completion and commissioning.
The 49MW/98MWh standalone project near Abernethy in Perth & Kinross, pictured, progressively came online from November 2023 as improvements to the site were signed off. The device was fully energised early last month.
The Jamesfield BESS includes two-hour duration Tesla Megapack lithium-ion batteries, enabled by Tesla’s Autobidder AI software for real-time trading and control. Leading independent renewable energy company RES is asset manager.
TagEnergy CEO Franck Woitiez said  “This is another important marker for TagEnergy in the UK and beyond, as we use our substantial expertise in storage to help stabilise the grid.
“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.”
Jamesfield is TagEnergy’s third UK storage project to become operational, after Hawkers Hill Energy Park and Chapel Farm.
Since formation in 2019, the developer has assembled a 12GW portfolio based on solar, wind and battery storage technologies, spread across the UK, Portugal, Spain, France and Australia. 1GW of the total is under construction or operation.
Harmony’s CEO Peter Kavanagh said: “The completion of 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, and are crucial for reducing Britain’s dependence on foreign gas imports.”
Jamesfield became a joint venture with Harmony Energy in November 2021, with TagEnergy’s acquisition of a 60% stake in the project. Santander UK supported the deal with £12.5m funding.
Those projects, together with other projects under construction, take TagEnergy’s secured portfolio in the UK to date to 320MW/640MWh.Â
