Mactaquac Life Achievement Project
New Brunswick’s Crown-owned electric utility, NB Power, is preparing the 672-megawatt Mactaquac Generation Station for a major overhaul aimed at extending its operational life to 2068. According to Natural Resources Canada, the new federal funding will support technical studies, regulatory reviews, First Nations engagement, and planning for the Mactaquac Life Achievement Project.
The dam has faced structural challenges since the 1980s due to a chemical process called alkali-aggregate reaction, which causes concrete to swell and crack. In 2016, NB Power agreed to a plan to spend up to $3.6 billion to prolong the dam's life, as it would have otherwise been decommissioned by 2030. On Tuesday, NB Power CEO Lori Clark stated that the total cost for the project is now expected to be close to $9 billion.
