Ontario Power Generation Inc. (OPG) is Ontario’s largest electricity generator. Under section 78.1 of the Ontario Energy Board Act, 1998, the OEB is authorized to determine the payment amounts to be made to OPG with respect to the output of certain of OPG’s generation facilities. These prescribed generation facilities are the nuclear generating stations operated by OPG (Pickering and Darlington), OPG’s baseload hydroelectric generation facilities (De Cew I, De Cew II, Sir Adam Beck I, Sir Adam Beck II, Sir Adam Beck pump storage generating station and R.H. Saunders), and 48 other hydroelectric generation facilities in the province.
Ontario Regulation 53/05, Payments Under Section 78.1 of the Act, (O.Reg. 53/05), sets out certain rules to be followed by the OEB in determining payment amounts for the prescribed generation facilities.
In accordance with the OEB’s approval of the settlement proposal in OPG’s 2022-2026 Payment Amounts proceeding, OPG is required to file certain reports with the OEB on a quarterly or annual basis that are to be posted publicly on the OEB’s website.
The sections below provide the reporting requirements and the reports received to date.
