World’s First Commercial-Scale Tidal Power Turbine Begins Feeding Electricity to the Grid
SeaGen more than four times the size of next largest tidal turbine
The world’s first commercial-scale tidal turbine, developed by British tidal energy company, Marine Current Turbines, has delivered electricity onto the grid for the first time. In principle, SeaGen works much like an “underwater windmill” with the rotors driven by the power of the tidal currents rather than the wind. Conservative estimates suggest there is at least five gigawatts of power in tidal flows in Britain, but there could be as much as 15GW.
The tidal current turbine, known as SeaGen, has briefly generated 150kW of power onto the grid as part of its commissioning work, ahead of it achieving full capacity a few weeks from now. SeaGen’s power is being intentionally constrained to 300kW during the commissioning phase, but once fully operational, it will generate 1.2MW of clean, renewable energy to the equivalent of 1000 homes.
