Electronic Funds Transfer and Electronic Remittance Details
Ontario Power Generation (OPG) is pleased to announce the implementation of Electronic Funds Transfer (EFT) for Canadian supplier based invoice payments as of July 9th, 2002. 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 the introduction of EFT, OPG is also introducing electronic remittances. OPG will be providing 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.

Ontario Power Generation (OPG) is also pleased to announce the implementation of Automated Clearing House (ACH) for U.S. supplier based invoice payments as of July 5th, 2007.

If you are interested in receiving your payment via EFT or ACH, please complete and return the following EFT registration form if you are a Canadian vendor or ACH registration form if you are a US vendor.
