OEB applications
Setting rates with transparency and public input
Ontario Power Generation (OPG) is the only electricity generator in the province that undergoes a public review of its rates by the Ontario Energy Board (OEB).
OPG files an application and the rates set by the OEB ensure we can continue to deliver clean, safe, and reliable energy.
As mandated by the OEB Act, these application proceedings are conducted in an open and transparent manner and OPG’s application documents are publicly disclosed on this website. We also sometimes submit applications for our facilities and operations.
