SSE Files Plans For 100 MW Pumped Hydro Scheme

The title of this post is the same as that of this article on reNews.biz.

This is the sub-heading.

Proposal aims to convert iconic Sloy Power Station into storage facility by end of 2030

These three paragraphs outline the proposals.

SSE has submitted plans to the Scottish Government for the 100MW Sloy pumped storage hydro scheme.

The plans would see the existing Sloy Power Station – a conventional hydro power station – on the banks of Loch Lomond converted into a pumped storage hydro scheme with a pumping capacity of up to 100MW.

If given the green light, the converted Sloy scheme would be capable of delivering up to 16GWh of long-duration electricity storage capacity.

SSE intend to make an investment decision by late 2027 and this is said about increasing capacity.

As part of the planning application, SSE Renewables is also proposing to upgrade the existing 32.5MW G4 turbine to match its sister units, which would increase the station’s generating output by 7.5MW to 160MW.

This appears to be a world-class example of canny Scottish engineering.

The project would turn the current 152.5 MW hydroelectric power station into a 160 MW/16 GWh pumped storage hydroelectric power station.

Not a bad transformation, that was opened three years after I was born.
