Canadian 200 MW Commercial Tidal Power Project Announced

Big new developments in tidal power have been pretty weak of late, but here's one which could amp things up a bit. World Energy Research and Blue Energy Canada have signed an agreement to develop a 200 MW commercial tidal power project, Renewable Energy World reports. The cost is $500 million; the location isn't entirely clear. The technology? Blue Energy's vertical axis tidal turbine:Blue Energy touts their design:

Four fixed hydrofoil blades of the turbine are connected to a rotor that drives an integrated gearbox and electrical generator assembly. The turbine is mounted in a durable concrete marine caisson which anchors the unit to the ocean floor, directs flow through the turbine further concentrating the resource supporting the coupler, gearbox, and generator above it. These sit above the surface of the water and are readily accessible for maintenance and repair. The hydrofoil blades employ a hydrodynamic lift principal that causes the turbine foils to move proportionately faster than the speed of the surrounding water.

The big deal in all this? 200 MW is seriously larger than any tidal turbine project currently operational.
