Alstom has completed its acquisition of tidal stream turbine designer and manufacturer Tidal Generation from Rolls-Royce.
The deal was announced last year and was subject to the successful installation of a 1 MW tidal turbine at the European Marine Energy Centre’s full-scale test site in Orkney, Scotland.
This took place last week, with the 1MW tidal turbine fitted on the same tripod support structure used to deploy a previously tested 500kW device.
The 1 MW turbine will now be tested in different operational conditions off Orkney over an 18 month period.
The turbine has a rotor diameter of 18 metres, a 22 m-long nacelle and a weight of 150 tonnes. It has three pitchable blades and operates, fully submerged, at a water depth of 40 meters, by rotating to face the incoming tide.
Jacques Jamart, senior vice-president of Alstom New Energies, said: “This new milestone installation is a step further towards the commercialisation of this new power solution.”
