RES sells 20MW EFR battery storage project to infrastructure group TRIG


Renewable energy firm RES has agreed to sell its 20MW battery storage project at Broxburn, West Lothian to The Renewables Infrastructure Group (TRIG).

TRIG said its total project investment will be £20m. The firm works closely with RES, and has acquired around 20 projects from the developer.

The battery storage project, due to be completed next year, was awarded an Enhanced Frequency Response contract outside of the main EFR tender last year. Announcing the deal, TRIG noted the bespoke, bilateral four-year deal with National Grid and associated availability payments.

It is the second EFR project sold by RES in recent months after the group sold its 35MW Port of Tyne battery storage project to private equity firm Foresight Group in June.

TRIG said once Broxburn was complete, its portfolio would stand at 774MW across 56 projects.

“The use of battery storage is becoming increasingly important in enabling grid networks to match fluctuations in the supply and demand of electricity and to stabilise power frequency,” said TRIG chairman Helen Mahy.

“This becomes especially vital as the installed base of renewables generation increases. We are excited to be playing a part in this by investing in Broxburn, one of the first large-scale commercial power storage projects to be developed in the UK.”
