Buccleuch and Foresight Energy Infrastructure Partners have reached a deal for investment in the Glenmuckloch pumped storage hydro (PSH) and wind farm project in Dumfries and Galloway.
Foresight's energy transition fund is to invest in and then lease the 1,547 acre site, with the aim of bringing the project to fruition.
The project, located at the disused opencast coal mine near Kirkconnel, will see the construction of a co-located 1,600 MWh capacity PSH plant and a 33.6 MW wind farm.
