Cape Sharp Tidal

CSTV, a joint venture of OpenHydro, a DCNS Group company, and its Canadian partner Emera successfully deployed Canada’s first grid-connected 2MW demonstration turbine in 2016.

CSTV’s second turbine, planned for deployment in 2017, is identical: 2MW with a 16-meter diameter rotor. When complete, the total demonstration project output is expected to be 4MW, displacing the need to burn about 2,000 tonnes of coal, and eliminate 6,000 tonnes of greenhouse gas (GHG) C02 emissions—the equivalent of taking 1,000 cars off the road each year.

To date, CSTV has announced contract awards of $33 million to Nova Scotia firms, including:

  • $25 million to Aecon and Lengkeek Dartmouth – Lengkeek for barge design and Aecon to manufacture the turbines – employing more than 150, including 100 new positions
  • $4.6 million to Hawboldt of Chester to design heavy-lift winches
  • Atlantic Towing Ltd. of Dartmouth for its marine operations support
  • Hundreds of other contracts awarded for services, manufacturing, technology and more (more than 125 Nova Scotia companies make up the CSTV supply chain).

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.
