A new report for Nova Scotia's consumer advocate is slamming Nova Scotia Power's analysis of the Muskrat Falls project, calling it flawed and biased.

The proposed Labrador hydroelectric dam would send electricity to Nova Scotia through an underwater cable called the Maritime Link.

The new report is by Levitan & Associates Inc., a Boston-based energy management consulting firm that was hired by the consumer advocate.

Three experts at the company testified at the Utility and Review Board. They disputed the claim that hydro power from Labrador is the cheapest renewable power option for the province.

They argue wind power is the best solution.

Liberal MLA Andrew Younger says that's a powerful new voice in the debate.

"This isn't coming from the Liberal Party," he said. "This isn't coming from the Lower Fair Rates Alliance."

Younger called this the most independent look at the project so far.

"They're saying that the government got it wrong, Nova Scotia Power got it wrong, and that they are torqing this process in order to get the result they want."

'Damning evidence'

In the legislative assembly Wednesday, Younger faced off with Premier Darrell Dexter over the report.  

"The government and Nova Scotia Power tailored their reports to support this project," Younger said. "That is damning evidence."

Dexter said it's just one more expert opinion.

"The Liberal Party of Nova Scotia would rather put the fate of Atlantic Canada in the hands of Quebec Hydro," he said. "They would rather sell out the security of Atlantic Canada to one of the largest monopolies in the world."

Dexter said his confidence in the project won't be wavered by one report.

"In fact, what I am is even more confident in the fact there are so many expert reports that are coming forward that support the Maritime Link," he said.

Dexter said most experts are backing the government's view that the Maritime Link is Nova Scotia's best bet for lower power rates.

The Maritime Link would bring 500 megawatts of hydroelectricty into Nova Scotia.
