Wikipedia: Pumped-storage hydroelectricityThe technique is currently the most cost-effective means of storing large amounts of electrical energy on an operating basis, but capital costs and the presence of appropriate geography are critical decision factors.
That is one hell of a proposition! Workable and a nice way to plan for the future. Though the costing will be floating a there is no way to predict for inflation raw material costs etc on a project of this magnitude. If used to generate an exportable commodity as other options are depleted then it will pay for its self over time.
World’s 10 Largest Construction Projects Sellafield Nuclear Site, England $30 billion Sellafield is the U.K.'s primary nuclear-fuel reprocessing facility. Located in Cumbria, 70 miles north of Liverpool, the plant covers 700 acres and employs 11,000 workers. Perhaps most notably, it is home to world's first commercial nuclear power plant, Calder Hall, which ended its 47 years of duty in 2003. In 2008, Nuclear Management Partners Ltd. (a consortium made up of Amec, URS and Areva) was hired to operate, clean up, and ultimately decommission Sellafield. The process will take more than a century. By 2120, the NDA expects the Sellafield site will have achieved brownfield status.
Yet my main concern would be the infrastructure required to forward this.
Considering the trouble and objections that appeared over the Beauly to Denny power lines then is ther not a chance of more?
The highlands may have the raw materal for the power but its wilderness and remoteness can throw up more challenges thus forcing a cost increase.
The construction of the rail network to the Highlands and the building of the Caladonian Canal are a good example. Ok they were 19c breakthroughs but even with modern methods it is one hell of a challenge.
I have to say Peter, that although we have our differences on a lot of points, this one appears very well thought out and apparently workable. It could generate electricity for decades to come.Nice oneH.
One question for Peter though "How will it affect the fishing?"
13 FISH13.1 Introduction13.1.1 An assessment has been carried out to identify potential impacts on fish as a result of theconstruction and operation of the Development.13.1.2 The assessment has been informed through consultations with Scottish EnvironmentProtection Agency (SEPA), Scottish Natural Heritage (SNH), Lochaber District SalmonFisheries Board (LDSFB) and Lochaber and District Fisheries Trust (LDFT) regarding the typeand extent of fish surveys required. Within the vicinity of the Development, the finalised scopeof the fish survey work included a fish habitat survey, an electric fishing survey, a survey of thelittoral habitats in Loch a’ Choire Ghlais and a shoreline habitat survey of Loch Lochy.13.2 Assessment Summary13.2.1 The assessment concluded that potentially significant negative impacts during construction ofthe Development would be limited to permanent habitat loss and fragmentation at Loch a'Choire Ghlais and Allt a' Choire Ghlais from inundation of the area behind the dam, andtemporary deterioration of water quality in all waterbodies from construction activities. This islikely to have a negative impact on trout habitat and a brown trout population within the area ofthe proposed dam and reservoir.13.2.2 Effective mitigation could be put in place to ensure pollution events are kept to a minimum toavoid deterioration of water quality.13.2.3 The assessment further concluded that no significant effects during operation of theDevelopment on fish are anticipated.
I couldn't make out if there were any farms or homesteads of any kind in the area to be flooded, or in the possible flood area if it suffered a breach.but apart from the naff name the dodgy video the dam itself looks feasible

The land is poor in the farming sense and you are more likely to run over a deer than a stray sheep. We have to think of the future before its too late. Besides to me the proposals appeal to me a lot more than wind farms. The one above Stirling may provide power but it is a carbuncle on the view over the hills and spoils the beauty of the area. To me the gain from hydro power is way ahead of the gain from wind power and has less of an impact enviromentally.
