Information for participants

GreenPower assesses each renewable gas project and certificate trader before they can participate in the certification, and audits all renewable gas declarations and certificate sales. This gives renewable gas customers confidence that they get what they are paying for.

Below, you can find useful information on the certification rules, how to apply to become a  participant, and how to use the certificate registry.

Participant fees

The National GreenPower Accreditation Program operates on a cost recovery basis from industry participants. The Renewable Gas Certification Fees are calculated to cover the operating costs of administering the Certification and the Registry operations. Fees are subject to annual review and notification to Participants by the Program Manager.

Fees for Participants 2025

An annual participation fee of $5,000 excluding goods and services tax (GST) applies for both Trader and Producer participants. The annual participation fee covers all uses of the registry including the creation and retirement of RGGOs. 

The fee applies once for each participating entity, meaning only one annual fee of $5,000 excluding GST is charged if the same entity participates both as a Trader and Producer. The Participant fee is invoiced to Participants at the start of each calendar year by the GreenPower Program Manager and it covers participation in that calendar year. Participants have 30 days to settle the invoice. 

If you join throughout the year, the first fee will be calculated based on the date of execution of the Participant Agreement on a daily pro-rata basis. Fees will not be reimbursed if a Participant leaves the program during a calendar year. 

For a Producer that has more than one renewable gas project participating in the Certification, a setup fee of $1,500 excluding GST for each additional renewable gas project will be invoiced upon accreditation of the renewable gas project. The annual participation fee remains $5,000 excluding GST regardless of the number of renewable gas projects a Producer has participating in the Certification.
