Over 100 hundred years ago, Sudbury became the first community in Ontario to own and operate its own electricity generating facility. The peak demand for electricity has evolved from the original 75 thousand watts (75 Kilowatts) to a high of 200 million watts (200 Megawatts) and now is about 150 million watts (150 Megawatts), but the motivation remains to keep Greater Sudbury Hydro customers at the leading-edge of innovation.

From the original steam-powered plant, we have moved to 30 substations controlled by the latest in computerized equipment. This system supplies reliable electricity to residential and commercial customers, insuring that the community has the electrical infrastructure to grow and prosper in an evolving energy marketplace.

At Greater Sudbury Hydro, we’re proud of our over 100 year history as Responsible, Responsive and Reliable electricity distributors to the over 47,400 homes and business we serve.
