SeaGen S, installed in Strangford Lough in 2008, was the first marine renewable energy project to be accredited by OFGEM as a commercial power station and regularly runs at full rated power. It has generated over 3GWhr - more than 10-times the rest of the declared yield from the tidal stream industry combined.
The 1.2MW SeaGen S system is capable of delivering up to 10MWh per in Strangford, which totals up to 6,000MWh per year. This is approximately the rate of energy capture of a 2.4MW wind turbine. Tidal energy is therefore more predictable than wind and potentially twice as productive.
