Scotland surges ahead with new 10MW tidal farm

[The Straight Story]

Taking advantage of the steady sea currents that flow through the underwater canyon walls in the sound of Islay, off the southwest coast of Scotland, between the islands of Islay and Jura, the Scottish energy company ScottishPower Renewables (SPR) has been given the go-ahead by the Scottish government to begin installing 10 underwater HS100 tidal turbines (made by Hammerfest Strom, a Norwegian company) on the ocean floor.

As countries all over the world seek energy alternatives to oil and coal, the UK, and Scotland in particular have come to see the value of tidal currents as a renewable resource, and no wonder; according to John Swinney, the Scottish finance secretary, the waterways around Scotland comprise nearly 25% of Europe’s total tidal resources.

The choice of the HS100 follows up experience learned from the installation of a 300kw experimental operation in Kvalsundet, Norway, which has been running for six years. SPR is also currently installing a single unit in Orkney (the small island chain in the north of Scotland) to provide a learning lab for the eventual installation in the Islay Sound.

The new 10MW current farm, similar in appearance to an underwater wind farm, will be the largest such operation ever undertaken, and is expected to more than double the energy capacity now being used on the existing grid to support over 5000 homes and businesses.
