Ontario’s clean energy provider

Ontario Power Generation produces almost half of the electricity that Ontario homes, schools, hospitals and businesses rely on each day, at a price that is approximately 40% less than the average of other generators in Ontario.

OPG was established under the Business Corporations Act (Ontario) and is wholly owned by the Province of Ontario, which means every Ontarian is our energy partner.
