What is the Mactaquac Project?

Mactaquac Hydroelectric Generating Station is expected to reach the end of its service life in 2030. NB Power has identified three possible options for the station, each with broad implications for people and the natural environment. NB Power will seek input from experts, First Nations and all New Brunswickers before selecting a preferred option in 2016.
