Bristol-based MCT initially deployed its SeaGen device in April 2008, though it was not fully operational until early 2009. Since then it has delivered approximately 350 megawatt hours (MWh) of electricity to the onshore grid. MCT says its twin generators now typically produce 5MWh during each ebb and each flow of the tide, for a total of 20MWh a day or enough to power 1,500 homes.
