Ragged Chute

Ragged Chute is located on the Montreal River, about 25 kilometres south of New Liskeard in Northern Ontario. The site was originally developed in 1910 to supply compressed air to the local silver mining community in nearby Cobalt.

Today, the still-working air plant co-exists with the Ragged Chute hydro facility, a blend of old ingenuity with modern technology.

The Ragged Chute hydro plant was commissioned in the spring of 1991, and generates an average of 43,700 megawatt hours annually, representing a capacity utilization factor of 75 percent.

TransAlta owns and operates the Ragged Chute facility through its wholly owned subsidiary Canadian Hydro Developers.
