Tidal companies rolling out utility-scale plants like to say that theirs will be the "largest." When talking about the future, which has not yet materialized, it's fairly easy to make that claim as long as it is larger than anything that presently exists. Who actually ends up being the largest will be a matter of history once the future becomes the present. We've created this page (on Feb. 26, 2008) to track who is presently the largest, and whose claims to be the largest in the future are actually the biggest claims.
Note : This is a new page -- a work in progress. The items listed below are a beginning point of reference, and do not necessary represent the actual "largest" installations at present.
Incheon to Build World’s Largest Tidal Power Plant - The current largest is the Rance tidal plant in France with a capacity of 240MW, while another plant under construction in Shihwa Lake will have a capacity of 254MW. (Songdo.com May 10, 2007)
Largest Tidal Stream System Installed - Marine Current Turbines, has successfully completed the first installation phase of the 1.2MW SeaGen Tidal System into the fast-flowing waters of Strangford Narrows off the coast of Northern Ireland. (The Energy Blog'' April 6, 2008)
Incheon to Build World’s Largest Tidal Power Plant - The city of Incheon plans to construct the world's largest tidal power plant on Ganghwa Island. The project will start with the construction of a 7.8-km-long dam connecting the four islands of Ganghwa, Gyodong, Seokmo and Seogeom at a cost of W1.78 trillion (US$1=W927). It should be finished by 2014. Following the installation of 32 tidal power generators, power will begin to flow in 2015. At 812 megawatts (MW), the Ganghwa plant will have the largest output capacity of any tidal plant in the world. (Songdo.com May 10, 2007)
