The best evidence we have about fish and mammal interactions with in-stream tidal is turbines is from other tidal deployments around the world.
In more than ten years of monitoring, which is conducted by an independent scientific agency, there hasn’t been a single recorded incident of fish, mammal or sea bird collision.
An underwater camera captures the behaviour of a very large group of pollock shoaling around a turbine at slack tide. Shoaling fish move away from the turbine as the tidal speed increases to the point where the turbine starts to spin.
Like this turbine, the Cape Sharp Tidal turbines will move at about a walking speed, which is 6-8 RPMs, which is walking speed, and much slower than wind turbines.
Nova Scotia’s Bay of Fundy tidal site is the most studied of any tidal energy test site in the world.
In ten years, there has been more than a hundred tidal energy development consultations and engagement opportunities with more than 1,000 people.
More than $15 million has been invested in research, studies, monitoring equipment and analysis. This will advance global understanding of how we can safely and responsibly harness tidal energy.
