Scotland Plans World's First Tidal Turbine Farms

September 29th, 2008 by  


The two projects, which each include 20 underwater turbines, will be finished within three years and will provide power to 40,000 homes.

ScottishPower Renewables will apply for planning permission next year to build the two farms in Northern Ireland’s seabed. The turbines will be manufactured in Scotland in an intentional boost to the country’s green-collar job market.[social_buttons]

The 98-foot structures have been tested to operate in water as deep as 328 feet, and they spin slow enough to allow marine life to avoid the 66-foot blades. Most boats and ships would not be affected by the farms since the turbines won’t even reach 30-feet below the surface, but net-towing trawlers will be forbidden from the area.

“Tidal power is completely renewable, being driven by the gravity of the sun and moon, with no carbon dioxide emissions, plus the added benefit of being entirely predictable,” said Keith Anderson, the director of ScottishPower Renewables. The farms would help Scotland attain its goal to reduce its carbon footprint by 80% by 2050.

New York City installed its first turbine for their tidal power farm earlier this month, but the Scottish plan differs in that the farms will be located in the open sea, not a river or straight.
