Eastern Ontario communities

Ontario Power Generation has been proudly operating in Eastern Ontario for over 100 years. Today we have one thermal facility and 10 hydroelectric generating stations on the St. Lawrence, Ottawa and Madawaska Rivers.

These stations, their employees and host communities play an important role in generating clean, reliable power for Ontario.

See how we are a part of communities across Eastern Ontario and learn about our many local programs, initiatives and events.

At OPG, we have a purpose that goes beyond generating clean, reliable, low-cost power – we’re helping generate a stronger, cleaner more prosperous Ontario.

Generating power with purpose

Our role in Ontario isn’t just measured by kilowatts (although we’re really good at producing them); it’s measured by our relationships, the impact we make and the future we leave to the next generation. That’s why we strive to be good corporate citizens who care about the environmental, economic and social wellbeing of all Ontario.

Generating community spirit

OPG’s Corporate Citizenship Program focuses on these areas:

Environment
Education, and
Community (health and safety, arts and culture, youth amateur sport, humanitarian and local causes), including support of Indigenous initiatives.

We are proud to support our over 175 community partners and events in Eastern Ontario like the Akwesasne International Powwow, the Renfrew County Regional Science Fair and Ducks Unlimited Kingston.

The result of this work is the Madawaska River Water Management Plan, which includes operational plans for each waterpower facility or dam, provisions for management of water levels and flows, stakeholder communication and environmental programming.
