Invoicing OPG
For consistency and transparency, all Ontario Power Generation (OPG) vendors submitting invoices to OPG are required to use the Ariba Network. We encourage all suppliers to please refer to your purchase order for invoicing instructions. For help submitting your invoice using Ariba, please contact ariba@opg.com.
OPG automatically does not accept invoices for purchase orders that do not require an invoice for payment.
Evaluated receipt settlement (no invoice required)
For evaluated receipt settlement (ERS) purchase orders, do not submit invoices against this PO.
OPG will automatically create a payment invoice upon receipt of material against an OPG purchase order. Payment amounts are based on the prices contained within the purchase order.
Electronic payment and remittance
For Canadian suppliers, this is referred to as electronic funds transfer (EFT) and automated clearing house (ACH) for U.S. supplier invoice payments.
Invoice payments will be made directly to the supplier's bank account. This process reduces the time required for suppliers to receive their payment by eliminating mail and deposit time.
In addition to electronic payment, we also use electronic remittances. OPG will provide payment details to you via fax, email or the bank’s EDI 820 message.
