Cape Sharp Tidal delays Bay of Fundy turbine project

A tidal project in the Bay of Fundyhas been put on hold both by the company behind it and Nova Scotia's Environment Departmentin the wake of criticism by local fishermen.

Cape Sharp Tidal, a venture backed by energy companiesEmera and OpenHydro,was scheduled to movethe first of two five-storey high, two-megawattturbinesfrom Pictou, N.S., this weekend for installation in the Minas Passage later this month.

Paul Laberge, project lead for Emera, said the company has consulted extensively, but wants to speak furtherwith fishermen worried about environmental impacts, particularly on shellfish, scallops, lobsters and whales.

"We're taking the opportunity to pause the deployment," Laberge told CBC's Mainstreet.

Science questioned

Cape Sharp Tidal's giant turbines are designed to capture energy from the moon's gravityin the Bay ofFundy'stidal bore, the most extremein the world. The turbines are expected to generate enough electricity to power 1,000 homes.

Some community members opposethe project and worry the turbines will affect larvae and mammals in the water.

They have called for better government oversight, pointing to afederal Department of Fisheries and Oceans report released in Maythat found holes in the environmental monitoring program.

The report saidbaseline data measuring species in the area and ability to measuremortality rates was insufficient. But DFO also agreed the project should still go ahead.

The turbine spinsat walking speed and is "hardly detectable" by fish,Labergesaid. He addedsimilar projects elsewhere in the world cause no issues.

Monitoring program not ready

As for the province, it needs to approve the company's environments effects monitoring program, developed byFundyOcean Research Center for Energy, before authorizing any turbines in the water.

"The environment monitoring program isn't ready yet,"Environment Minister Margaret Millertold CBC NewsThursday afternoon.

"It's not going to go out until we're happy."

The company expectedto have that approved ahead ofinstallation,Laberge said in an interview, and has heard nothing to the contrary.

"Moving the turbine, it's a couple weektransit time around the province," he said. "Our expectation was that all the approvals would be in place."

The department is reviewing the information, and Miller didnot have a timeline for when it might authorize the turbine installation.

'Science and the evidence'

She said the company's decision to delay shipping the turbines isa "really good move" as it may ease some fears,but that the Department of Environment will make its decisions based on science and evidence.

Theprovincial government and theFundy Ocean Research Center for Energy have done more than 70 impact studies ahead of the project,the centre's general manager, Tony Wrigh, told CBC.

"We'll never have the complete picture," hesaid."We could spend hundreds of millions more and so we'll never have a complete understanding of this kind of environment, but we've got a pretty good one."

He said to get a tidal energyindustry going, Cape Sharp Tidal needs to put the turbine in the water and see what happens.

'Zero respect for the environment'

ColinSproul, spokesmanfor the Bay ofFundyInshore Fishermen's Association, said the installation delay is a "welcome development," but not what he wanted.

He worries the turbines will harmfish and whales and endanger an established industry.

"Maybe there's a way in the future to harness the power of theMinasPassage, but certainly not with tidalin-stream devices,"Sproulsaid. "That shows zero respect for the environment."

He said the association has asked the company to halt installation, remove equipment, and undertake a new ecology study with oversight from DFO, along with input from industry, community and First Nations representatives.
