SeaGen was the world's first large scale commercial tidal stream generator.[1][2][3] It was four times more powerful than any other tidal stream generator in the world at the time of installation.[4] It was decommissioned by SIMEC Atlantis Energy Limited in summer 2019, having exported 11.6 GWh to the grid since 2008.[5]
The first SeaGen generator was installed in Strangford Narrows between Strangford and Portaferry in Northern Ireland. Strangford Lough was also the site of the first known tide mill in the world, the Nendrum Monastery mill where remains dating from 787 CE have been excavated.
