Cape Sharp Tidal

Cape Sharp Tidal—a joint venture between Emera and OpenHydro, a DCNS company—were selected by the Nova Scotia Department of Energy for tidal energy demonstration project at the FORCE test site.

Cape Sharp Tidal aims to deploy a fully grid-connected 4MW tidal array in the Bay of Fundy, starting with a 2MW turbine deployment in 2015. This project has potential to be one of the world’s first multi-megawatt arrays of interconnected tidal turbines, providing energy to more than 1,000 customers in Nova Scotia.

The 4MW demonstration array will be the first phase of a commercial-scale project which, subject to regulatory approvals and environmental effects monitoring, may growTURBINE-ARRAY-v6-2 to larger output.

The project uses OpenHydro’s Open-Centre Turbine. It has a simple design with four key components: a horizontal axis rotor, a magnet generator, a hydrodynamic duct and a subsea gravity base foundation. The turbine base sits directly on the seabed floor, out of the way of ships, and without drilling.

Cape Sharp Tidal is committed to establishing a local manufacturing hub in the Bay of Fundy area to support large-scale tidal energy by investing 70 percent of phase 1 project costs in Nova Scotia. The company’s goal is to create up to 1,000 jobs by the 2020s. The project’s key local industrial partners are Aecon, Lengkeek Vessel Engineering, Hawboldt Industries and Atlantic Towing.

About OpenHydro

OpenHydro is a DCNS company specialising in the design, manufacture and installation of marine turbines generating renewable energy from tidal streams. The company’s vision is to deploy turbine arrays under the surface of the oceans to produce energy silently, invisibly and with no impact on the environment. OpenHydro has achieved a number of industry firsts including being the first to deploy a tidal turbine at the European Marine Energy Centre (EMEC), the first to connect to and generate electricity from tidal streams onto the UK National Grid and the first to successfully demonstrate a method of safely and economically deploying and recovering turbines directly on the seabed. The deployment and recovery method delivers a step change in the economics of tidal energy.

OpenHydro has a project portfolio spanning Canada, France, Northern Ireland, Scotland and the Channel Islands with utility partners including Emera, EDF, Brookfield Renewable Energy Group, SSE Renewables and Alderney Renewable Energy. OpenHydro has won a number of awards for its innovations in the field of renewable energy technology.

Past Experience

Nova Scotia Power, with technology partner OpenHydro, deployed North America’s first 1 MW in-stream tidal turbine in the Minas Passage on November 12, 2009. A 400-tonne gravity base, built by Cherubini Metal Works in Dartmouth, held the unit in place. OpenHydro’s open-centre, axial flow design involves no oils or lubricants for protection of the environment. Tidal forces at the site greatly exceeded modeling and popped the turbine’s blades from the six-metre-diameter rotor. Nova Scotia Power and OpenHydro successfully recovered the turbine and gravity base on December 16, 2010 – another milestone in tidal energy development for Nova Scotia.
