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

Pelly's Space
Pelly is a uranium pellet who loves powering nuclear generation, bananas, and hanging out with his besties.

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.

Madawaska River Water Management
OPG works with local waterpower companies and the Ministry of Natural Resources on a balanced approach to water management on the Madawaska River that considers the various interests of many users.
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.
