ALSTOM INDUSTRY PROFILE MOU
Successes such as that have led to Alstom signing and Memorandum of Understanding with ScottishPower Renewables to incorporate Alstom’s tidal power devices into the Sound of Islay project which will see four of Alstom’s 1 MW tidal devices deployed between the islands of Islay and Jura on the west coast of Scotland.
The Islay programme remains on schedule for the first unit to be deployed in late 2015, with full site deployment during 2016. Operations are planned for 25 years and the demonstration project is anticipated to be the launch pad for future larger scale sites around the Scottish coast.
“We believe the potential for tidal power in the UK is huge and with our turbine, we have the ability to help our customers make the best of that potential,” said Alstom Ocean Vice- President Rob Stevenson.
SPECIFICATIONS
Alstom’s tidal turbine consists of a three- bladed, pitch-controlled rotor, with a diameter measuring 18 metres, a standard drive-train and power electronics inside the nacelle. The 22m long nacelle is installed onto a separate seabed-mounted foundation and weighs less than 150 tonnes.
FEATURES
The tidal stream turbine has a number of notable features…
1. It is simple and easy to transport. Its buoyancy means that it is easily installed and retrieved in a single tidal cycle using small vessels, reducing installation and maintenance costs.
2. It has an intelligent nacelle. Thrusters rotate the nacelle to reflect the direction of the tide, managing ebb and flood tides seamlessly as well as maximising energy production.
3. With its efficient blades, turbine blade pitching can be altered to control load on the turbine and optimise use of the tidal conditions locally.
Tests on the turbine will continue throughout 2014, followed by deployment in the Sound of Islay and then on to commercialisation when the dreams of many engineers will finally come to fulfilment.
