Mactaquac Generating Station

The Mactaquac Generating Station is a run of the river hydro facility with an installed generation capacity of 660 MW, supplying about 12 per cent of New Brunswick homes and businesses with clean, low-cost power.

The facility began generating electricity in 1968. Since the 1980s, concrete portions of the hydro station have been affected by a chemical reaction called alkali-aggregate reaction. The reaction causes the concrete to swell and crack and has required substantial annual maintenance and repairs.

Mactaquac Life Achievement Project

NB Power is proposing a project to ensure the station can operate to its intended 100-year lifespan with a modified approach to maintenance and adjusting and replacing equipment over time. This recommendation follows three years of expert research, including input from science, engineers, the public and First Nations.

This approach will meet all safety and environmental requirements. It will allow NB Power to take into account changes in cost, technology and electricity demand while ensuring a steady supply of clean, renewable power for New Brunswickers.
