Loch a Bhraoin Hydro Begins Generating Using Pneumatic Mobile Weir Supplied by Dyrhoff Ltd

Loch a Bhraoin hydro began generating clean electricity in October. This 2MW project has the potential to generate enough electricity for 1,700 average UK homes, saving more than 3,800t of CO2 emissions annually. The scheme turned Loch a Bhraoin into a storage reservoir, with an innovative Obermeyer weir to control flood levels. The pneumatic weir, measuring 2.89m high x 18m wide, was supplied by Dyrhoff Ltd and installed in the summer, under supervision from Dyrhoff engineers. Dyrhoff Ltd are the European agents for Obermeyer.


The scheme also benefits from storage and aims to offer balancing services to the grid. It was developed by Inverbroom Hydro Ltd and Hugh Wallace’s Glendevon Energy Co Ltd and received funding from Clydesdale Bank and Thrive.

“It’s fantastic to see Loch a Bhraoin begin generating clean electricity, supporting the UK’s journey to net zero. Glendevon and other contractors have done a brilliant job completing this project on time despite the challenges COVID has presented. We’re really pleased to have been able to provide the mezzanine funding which helped get this project running.” Said Matthew Clayton, Managing Director, Thrive Renewables.
