Pre-design study about implementation of tidal turbine in Quebec

1. Study of the implementation of tidal turbines in Quebec Philippe KOUAMÉ Project Director Dominique Pelletier July 29th 2010

2. Outline of the presentation Introduction Methodology Results et discussion Conclusion et prospects

3. Introduction

5. What would be the necessary ways?

6. What would be the cost of electricity from these tidal turbines?

8. Results and discussion

9. Working of a tidal turbine

10. Technologicalprogress Hydrohelix (France) HS1000 , Hammerfest Strom (Norway) Unit cost: 325 000 $ Nominal power : 200 kW Unit cost: 16 215 000 $ Nominal power: 1 MW Annual output:700000 kWh/an

11. Skerries project, MCT (UK) Turbine Gorlov - GCK Technology Inc (USA) Nominal power: 1.5 MW for 2 turbines

12. Open center turbine- OceanenergyInc (USA-Florida) Nominal power: 2.4 MW

13. Davis Hydro Turbine - Blue Energy (Canada) Nominal power :5 à 25kW

15. The price of the kWh from tidal turbine would cost around 7¢ and 11¢ (BB&V 2006) comparatively to 6.60¢ for the city of Montreal at the same time (Hydro Québec)

16. After the payback of investment, the cost of the kWh would be equivalent and even less expensive than electricity from nuclear energy and hydropower (Blue Energy)

18. Minor Perturbations of the seabedwhichneed to beinvestigateddeeply

19. Installation stepcould have strong impacts with excavation and blasting

21. Results for Hudson strait

24. Predictablemany centuries ahead

25. No dependence on weather

27. Installation maybedifficults for the site with a waterflowabove3.5 m/sExcavation needsthe use of boat thatcanlean on seabed

28. Conclusion Tidal turbine’s implementation is less expensive than an hydroelectic dam’s implementation After payback on investment, the cost of electricity is identical or even less expensive than electricity from hydroelectricity For the environmental impacts, more researchs should be done and implementation projects should be submited to the BAPE
