TransAlta says wind farm rebuild will cost as much as $100M

A Canadian renewable-power company will replace foundations at a New Brunswick wind farm after engineers determined a turbine collapse in October stemmed from design flaws.

TransAlta Renewables Inc. said replacing 50 foundations will cost $75 million to $100 million (US$59 million to US$79 million) and take until the end of 2023. The Calgary-based company expects to lose $3.4 million per month in revenue while the turbines are off line, according to a statement Tuesday.

The foundation problems are limited to the 50 turbines at two sites in Kent Hills and there’s no indication of similar issues with the company’s other wind farms. TransAlta has more than 20 wind facilities in Canada and the U.S., according to its website.
