Norwegian 1 MW tidal turbine to Scotland

A 1 MW tidal turbine developed by Norwegian tidal company Hammerfest Strøm will be constructed in Scotland and tested at the European Marine Energy Centre (EMEC).

Fife-based Burntisland Fabrication Ltd (BiFab) will fabricate the sub-structure for the HS1000 tidal turbine, which will be deployed at EMEC in 2011.

The HS1000

  • Captures the water flow in both directions;
  • The nacelle is fixed;
  • Its tilted structure is said to minimise flow disturbances; and
  • It uses gravity foundation.

ScottishPower Renewables (SPR), a major shareholder in Hammerfest Strøm, has already submitted a planning application to install 10 HS1000 tidal turbines in the Sound of Islay off at the west coast of Scotland. Hammerfest Strøm has previously said they expect to deliver these in 2013.

Furthermore, SPR plans to develop a 95 tidal turbine project at the Ness of Duncansby in the Pentland Firth as part of the Crown Estate’s marine energy leasing round.

SPR Managing Director Keith Anderson says: “Following the deployment of the initial HS1000 machine in Orkney, SPR is planning to install 10 of the machines in the Sound of Islay, which will be the first tidal power array of its kind in the world. Following on from this,w e are also planning to install up to 95 tidal turbines in the Pentland Firth.

A 300 kW tidal turbine prototype, the HS300, has been operating at depths of 50 m in Kvalsundet, Hammerfest for around 6 years, and has been feeding into the grid since 2004.
