The Dryden facility is made up of the Wainwright, Eagle River and McKenzie Falls generating stations. These stations obtain water from large drainage areas, which include several large lakes. Together, the generating stations capture the energy of water to generate electricity, which is then delivered to Hydro One’s grid.

The three stations that make up the Dryden hydro power facility were constructed in the 1920s and 1930s and refurbished in 1986. The typical life span of a well-maintained hydro facility is about 100 years.
