Balliemeanoch Pumped Storage Hydro
Balliemeanoch Pumped Storage Hydro is a proposed pumped storage hydro (PSH) scheme in the Scottish Highlands. [1] [2] [3]
If built, the project will be the largest pumped-hydro scheme in Scotland, storing 45GWh of energy, equating to 30 hours of generation at the maximum capacity of 1.5GW.[2]
Like the nearby Cruachan Power Station, the project would use the 40km long Loch Awe as the lower reservoir.
In the hills to the East a small mountain lake, Lochan Airigh, lies in a wide valley at approximately 360m above Ordnance Datum (AOD), 9km northwest of Inveraray and 3km east of the village of Balliemeanoch.[2]
The upper reservoir would be created by damming the valley. The proposed dam would be 1500m long and 110m high at its tallest point.
When full the reservoir would be approximately a mile across. The water level, at an elevation of 425m AOD, would be 65m above the current level of Lochan Airigh. The working volume, of up to 58 million m3, corresponds to a one metre lowering of the water level of Loch Awe.[3]
Surplus electricity from the national grid would be stored by pumping water from Loch Awe up to Lochan Airigh, to be used as required.
