Tidal Turbine Contract

The first full-scale Neptune tidal stream device is the design of Edinburgh's Aquamarine Power Ltd. The 2.4MW Neptune demonstration design is on schedule for delivery in 2010 at the UK tidal test centre, known as the European Marine Energy Centre (EMEC), located in Orkney, as a precursor to commercial deployment. The device comprises two horizontal axis tidal turbines, which will be mounted on a single monopile for the commercial demonstrator. The device features bi-directional (flood and ebb) generation, with its design heavily influenced by wind turbine technology and as such gives predicted efficiencies of up to 45 per cent.
