The Analysis of Tidal Stream Power

Tidal Energy in Scotland - An Overview

It is estimated that about 25% of Europe's tidal energy resources could reside in Scotland's coastal areas. It is also thought that tidal power could easily contribute a third of Scotland's energy needs. With these facts in mind, Scottish Power Renewables have applied for planning permission for a tidal power installations of 10 large turbines to be sited on the seabed in the South of Islay. The chosen turbine for this project and for a larger 95-turbine project in the Pentland Firth is the HS1000 from Norwegian tidal power developer Hammerfest Strøm. Fife-based Burntisland Fabrication Limited (BiFab) has been awarded the largest single contract for the fabrication of the sub-structure for the first turbine, which will be installed at the European Marine Energy Centre in Orkney in late summer 2011.

Scottish Power Renewables have been a major shareholder in Hammerfest Strøm for the last 5 years, and have confirmed that they will be entering the Ness of Duncansbay project into the Scottish Government’s £10 million Saltire Prize for marine energy innovation.

Another major contender as a commercial tidal turbine is the Atlantis Resources AK1000, which was assembled in Scotlnad and unveiled at Invergordon in August before being shipped to the EMEC test site off Eday, Orkney where it has been installed on the seabed. The device stands 22.5m (73ft) tall on a gravity base and weighs 1,300 tonnes. It has two sets of blades on a single unit to harness ebb and flood tides and could generate one megawatt of power - enough electricity for about 1,000 homes. It is a more robust looking device than the Norwegian design*, but Hammerfest Strom appear to have taken the lead in this late-starting but exciting race.

*In November 2010 the experimental composite blades originally fitted to the AK1000 failed and the nacelle was recovered to the surface. New (GRP) blades are due to be fitted in May 2011
