Commercial-scale tidal energy now a reality


SeaGen tidal turbines in Northern Ireland are now producing enough power for 1,500 homes in the world’s first commercial-scale tidal energy installation. They’ve shown it can be done. May everyone else join in. All that tidal power is just waiting to be converted into completely reliable renewable energy. Unlike wind or solar, the movements of tides are completely predictable, so  while the power generation may only occur at certain times, those times are known.

SeaGen, the first commercial-scale tidal stream energy system has achieved a new milestone of 5 gigawatt-hours (GWh) of tidal power generation since starting operation at Strangford Lough in Northern Ireland. That equals the annual power consumption of 1,500 British households. The Siemens-owned system is one of the largest tidal stream power projects today.
