24 Aug Innovative $264m electricity scheme to boost Scottish energy production
Eishken Limited is planning the installation of a US$264 million large pumped storage hydro (PSH) scheme on the Island of Lewis, which will deliver a significant boost to energy production in Scotland.
The scheme will be capable of generating 300MW of electricity, enough to power more than 200,000 homes.
The PSH scheme will store electricity, primarily generated by wind farms on the Isle of Lewis.
The use of the Western Isles Link, the cable being installed by the National Grid to export and import electricity produced from the renewable energy sources on the island, will increase from 40% to 80%.
The proposed initiative will be adjacent to and form part of the already consented 162MW Muaitheabhal Wind Farm on the Isle of Lewis.
It will allow part of the output of the wind farm to be stored until required allowing it to balance the sometime intermittent nature of wind.
Nick Oppenheim of Eishken Limited said: “There are very few PSH schemes throughout the UK and what we are proposing is particularly innovative given the use of the sea as the lower reservoir.
“This scheme will not only materially enhance the benefits to be derived from the Western Isles link but will make a material difference in the supply of energy to the mainland. It will also be a key element in the Scotland’s renewable energy armoury.”
The company estimates that more than 150 jobs will be created during the three to five-year construction period.
