Plans were announced this week for a US$264 million 300-MW pumped-storage hydropower project on the Eishken Estate in the south east of the Isle of Lewis, the largest island of Scotland’s Outer Hebrides.
Eishken Ltd. is planning the installation of the scheme, which the company says could power more than 200,000 homes and possibly increase by 40% the use of the Western Isles Link. The link is the cable being installed by National Grid to export and import electricity generated from renewable energy sources on the islands.
The proposed scheme will be adjacent to and form part of the 162-MW Muaitheabhal wind farm, which already has planning consent. Eishken said the pumped-storage scheme “will permit part of the output of the wind farm to be stored until required, allowing it to balance the sometimes intermittent nature of wind.”
Eishken is expected to seek consent for the scheme later this year and according to published reports, AECOM is advising Eishken on the technical aspects of the project.
