An Energy Tide 2 (ET2) turbine generator unit (TGU) will be launched in Cobscook Bay, Maine early next year to demonstrate the performance of the commercial design of the Ocean Renewable Power Company's system, it was announced last week. The new installation follows a year-long demonstration program in 2008, and is expected to be followed with the installation of the first full-scale, grid-connected tidal TGU in Maine by the end of 2010.

The first commercial scale in-stream tidal turbine in the Bay of Fundy was deployed last week (12th November) by Nova Scotia Power and its tidal technology partner OpenHydro. The one-megawatt commercial scale turbine was deployed from the Fundy Ocean Research Centre for Energy (FORCE), in the Minas Passage.
