Ontario Power Generation Accounts Payable is a centralized invoicing function that covers an invoice or transaction from payment request to disbursement, document retention and archiving.


Please refer to your Purchase order for invoicing instructions. 

OPG accepts invoices submitted using the Ariba Network application. For help submitting your invoice using Ariba please contact

OPG implements Electronic Funds Transfer (EFT) for Canadian supplier-based invoice payments. Using EFT, invoice payments will be made directly to the supplier's bank account. This process eliminates mail and deposit time and is available to all Canadian based suppliers with a Canadian bank account. EFT also helps OPG by eliminating the process of issuing paper cheques and the postage costs for mailing.

In addition to EFT, OPG is also uses electronic remittances. OPG will provide payment details to you via your choice of fax or email. Soon, we will also make this information available on a vendor self-service Internet site. For our EDI suppliers, we can also issue this remittance detail through our bank as an EDI 820 message.
OPG is also uses Automated Clearing House (ACH) for U.S. supplier based invoice payments.
