OpenHydro Technology Canada Ltd.
At over 16 metres, the Bay of Fundy has the highest tidal range in the world. This unique site has also the potential to supply thousands of homes with clean and renewable energy, if the unequalled power of the tides could be harnessed. The conditions found in the Bay of Fundy are demonstrably harsher than other tidal sites around the world, representing a significant engineering challenge in developing devices to turn that energy into electricity in a cost effective manner. OpenHydro will deploy a 4-MW array (two 2-mw turbines) at the FORCE facility in the Bay of Fundy, simulating the cost and performance of a commercial tidal farm. The project will demonstrate and validate turbine spacing effects, control strategies, connectivity and cabling installation needed to sustain the operation of a tidal turbine array. Designed for the harsh conditions of the Bay of Fundy, each OpenHydro turbine is comprised of an outer fixed rim (stator) and an inner single-piece rotating disc (rotor) mounted on a subsea gravity base that is simply placed on the seabed. Each unit is expected to produce 2MW at a cost of 14.7 cents per kWh by 2020.
