Sloy

Sloy pumped storage
Our generation business, Scottish and Southern Energy Generation Ltd (SSEG) has submitted a planning application to extend the existing Sloy hydro-electric power plant with the construction of a new pumping station. This would enable SSE to produce an additional 100GWh (gigawatt hours) of electricity in a typical year to help meet peak demand.

Pumped storage schemes involve two bodies of water located at different heights. During periods of low demand for power, electricity is used to pump water from the lower loch to the upper reservoir. This water is then released to create power at a time when demand is high. A key advantage of developing a pumped storage scheme at Sloy is that the existing infrasctructure, such as the dam, is already in place.

The Sloy scheme came into operation in 1950 and is SSE’s most powerful conventional hydro scheme with an installed capacity of 152.5 MW .
