Buccleuch has announced that it has reached a landmark agreement for investment in the Pumped Storage Hydropower (“PSH”) and Glenmuckloch Wind Farm project in Dumfries and Galloway.

Foresight Energy Infrastructure Partners (“FEIP”), Foresight Group’s flagship energy transition fund, will invest in Glenmuckloch and lease the site to complete the project.

The project, located in the disused surface coal mine near Kirkconnel, Scotland, will see the construction of a 1,600 MWh PSH power station and a 33.6 MW wind farm. The investment will improve and facilitate the balancing of the UK electricity system allowing the integration of more renewable generation.

Once built, the PSH plant will have a storage capacity of 1,600 MWh that can be delivered at a rate of 210 MW per hour, providing 8 hours of storage capacity. Using two 105 MW reversible hydro-turbines, the site will store energy during periods of excess energy supply and release stored energy during periods of peak demand. The co-located wind farm will include 8 turbines of 4.2 MW and will have the capacity, via a direct connection, to supply the PSH plant.

The deal marks the culmination of Buccleuch’s day-to-day involvement with the project, although the company retains ownership of the land at Glenmuckloch.
After mining operator ATH Resources collapsed in 2013, Buccleuch worked tirelessly to avert potential environmental disaster at the site and, working with a range of partners, restored the site and then planned for a long-term future. for Glenmuckloch which should provide benefits. , economic and environmental for decades to come.

Benny Higgins, Executive Chairman of Buccleuch, said: “Buccleuch has long been talking about the huge potential of a PSH and wind farm project at Glenmuckloch, a project fully funded by the private sector. The project could have an incredibly positive impact on local communities, but also on a national level as we face the climate crisis. I am delighted that we have reached an agreement with Foresight, which will move the projects forward to the next stages and ultimately to energy production. Our gratitude goes to the local communities and stakeholders who have supported us over the past decade and enabled us to bring the project to a stage where it can enter its next phase.
