Mass Certificate Transfers (MCTs)
M-RETS allows for the mass transfer of certificates via CSV (.csv file type) to either an internal active account or an external organization.
Steps To Mass-Transfer Certificates: Creating the CSV transfer file
- Filter the Active certificates dashboard by the batches you wish to transfer. In this example below, we filtered by Vintage range of 01/2020 to 12/2020. Once filtered, we selected the Download button, you will need to take information from the downloaded CSV later.

- Navigate to the Registry Documents section of the M-RETS website (https://cleancounts.org/subscription-costs/electric-pricing-and-registry-documents/). Under the "Mass Certificate Transfers" section download the "Mass Certificate Transfers Template". We will then input the necessary information into the CSV.
- Column A Using the downloaded "Active Certificates" CSV from step one, copy the serial numbers into the "Mass Certificate Transfers Template".


- Column B Input the quantity you are transferring, you can transfer either the full batch or a partial quantity.
Please note: for columns C & D below you will only need to complete one column. You can either transfer certificates from one active account to another or transfer certificates externally to an organization.
- Column C If transferring to an external organization: You will need to obtain the organization ID from the org, this ID will begin with "MM" followed by several numbers.
- Column D If transferring to an internal active account: Obtain the Account ID by navigating to "Accounts" and copying the "Account ID".
- Column E You can include any notes that you would like to appear on the certificate transfer.
Uploading the MCT File
- Navigate to the "Certificates" Dashboard
- Select the "Upload" button at the top of the table.

- Select "Choose file" and then "Upload"

If there is an error with your upload or file you will receive an email from the M-RETS System detailing what the issue is. If the certificates are being sent to an external organization they will remain in a pending state until they are accepted.
