WWTurbine

In 2016, Water Wall Turbine (WWT) successfully deployed and conducted short-term testing of its 1 MW floating tidal turbine at Dent Island Lodge, British Columbia. The system featured a horizontal-axis, multi-blade turbine housed in a barge-like structure that floats on the water’s surface and is moored to the seabed, with the turbines partially submerged. Flowing water rotates the turbine, which drives a generator to produce electricity. The system integrated three major subsystems: the floating tidal turbine, a proprietary microgrid management system, and an energy storage system. The project included strong Canadian content, with over 30,000 person-hours spent on fabrication at local shipyards and manufacturing facilities. Supported by ecoEII and CEF funding, the installation included a 900-meter subsea cable and a custom mooring system designed to withstand over 100 tonnes of tidal force. While preliminary results showed strong power potential, extended testing planned for 2017 did not take place
