Regulated electricity rates

Ontario Power Generation is the largest clean energy generator in Ontario, producing more than half of the Province’s energy at a cost that's about a third less than other generators. OPG is also the only rate-regulated generator in the province.

See how most of OPG’s electricity production is regulated by the Ontario Energy Board, and the role we play in moderating the price of electricity in Ontario.

Regulated rates for Ontarians

OPG is the only generator in the province whose rates are set through public hearings with the Ontario Energy Board (OEB) and our net income benefits Ontario.

As mandated by the OEB Act, these rate application proceedings are conducted in an open and transparent manner and OPG’s application documents are publicly disclosed on this website.

Consulting consumers for accountability

During OPG’s rate applications, individual consumers or groups of electricity ratepayers may request to become intervenors, allowing them to participate directly in the public hearings and influence the OEB’s decision-making.

In preparation for its next rate application, OPG also consulted directly with Ontarians and stakeholders.

The rate application process makes OPG more accountable to Ontario’s consumers for our electricity rates than any other generator.
