The BBC online news magazine carried an article on March 10 that should be of interest to all those following the Muskrat Falls debate.
“Do massive dams ever make sense?” summarizes the work of researchers at Oxford University. They studied more than 245 large dams completed between 1934 and 2007.
A large dam is one with a wall height of more than 15 metres. Muskrat Falls would meet the study criteria
The researchers found that dams ran 96% over their approved budgets, on average. One Brazilian dam went 240% over budget. With few exceptions, the researchers found that the dams were not economically viable.
