RES has submitted a planning application to South Ayrshire Council for a 49.9MW energy storage proposal on land north east of Holmston roundabout, near Ayr.
If consented, Holmston Farm could help create a more stable electricity system, as well as supporting the increased deployment of renewable energy.
RES, a British company with a history of similar developments in Scotland, also argued that the site offers biodiversity enhancement opportunities through the planting of native trees, grassland and scrub areas.
