TagEnergy to build two 50MW battery storage facilities in partnership with Harmony Energy

16 November 2021

Global clean energy enterprise Tag Energy has grown its UK presence following the acquisition of a 60% stake in two 50MW battery storage projects in a joint venture with Harmony Energy.

Peter Kavanagh, Chief Executive Officer of Harmony Energy, said: “We are pleased to announce this deal with Tag Energy which has been under negotiation since January. This is the last stand alone battery transaction outside of the Harmony Energy Income Trust and we very much look forward to working with another highly experienced partner on these two sites.”

The projects will increase the country’s energy storage capabilities and add flexibility and stability to the UK grid to support the transition to a clean energy future.

Both projects will use Tesla Megapack lithium-ion batteries, together with Tesla’s Autobidder AI software for real-time trading and control.

The deal comprises:

  • Chapel Farm standalone Battery Energy Storage System of 49.5MW/99MWh near Luton, England; and
  • Jamesfield Farm standalone Battery Energy Storage System of 49MW/98MWh near Abernethy, Scotland.

Construction of both projects will commence in Q1 2022, with commissioning in Q1 2023. The projects represent a combined investment of close to £60m.

The dual projects are TagEnergy’s third investment in battery storage facilities in the UK as it deploys its significant storage expertise to drive growth in the country’s rapidly expanding renewables market.

TagEnergy entered the UK market in 2021, with commencement of construction by TagEnergy and Tesla of the Hawkers Hill Energy Park battery storage facility in Dorset in September, and the acquisition by TagEnergy of the Roaring Hill Energy Storage Project in Fife, Scotland last month.

The four battery storage projects announced to date take TagEnergy’s secured portfolio in the UK to 170MW/340MWh.

Franck Woitiez, Chief Executive Officer, TagEnergy said: “These projects underscore TagEnergy’s commitment to leveraging our strong storage expertise to support the UK grid in connecting more sustainable, competitive and clean power to accelerate the energy transition.

“We look forward to working closely with Harmony Energy to enable an increasing flow of clean energy from renewable sources,” Mr Woitiez said.

Peter Kavanagh adds: “It’s widely recognised that battery storage is critical to achieving Net Zero in the UK and projects of this size – delivered without subsidies – will be vital in providing flexibility to the grid. We are looking forward to working with TagEnergy on these projects.”
