Hertfordshire-based renewable energy company RES has announced the sale of the 50MW Roaring Hill Energy Storage Project near Glenrothes in Fife to international clean energy investors TagEnergy.

Roaring Hill consists of 18 battery enclosures and was consented in two phases by Fife Council.

“The modern and highly efficient battery energy storage system will provide grid stabilisation and ancillary grid services, supporting the network by balancing supply and demand,” said RES.

“Battery energy storage is a key technology providing flexibility to the network and supporting the decarbonisation of the UK’s electricity system by 2035.”

TagEnergy is part of the Impala SAS Group, founded and owned by French businessman Jacques Veyrat.

The firm has developed a portfolio of 2GW in the UK, Australia, Spain, Portugal and France.

Lucy Whitford, MD for Development and Construction at RES, said: “We are pleased to be working with TagEnergy, and look forward to supporting them as they deliver the project.

“This latest energy storage project will help support the network as we transition to net zero and underlines the position of RES as a reliable, economic and safe choice for energy storage customers in the UK.”

TagEnergy CEO Franck Woitiez said: “This is an important step forward for TagEnergy as we seek to drive the pace of transition to renewables through projects that deliver reliable energy affordably and at scale.

“Our significant battery storage expertise means we can leverage our flexible energy supply to optimise the energy market while helping to stabilise the grid and increasing renewables’ share of it.

“We are pleased to be working with RES, whose experience in developing and managing energy storage systems is world-leading.”
