A cancellation statement is the official receipt issued by the certificate registry confirming that specific renewable‑energy certificates have been permanently retired on your behalf, listing their serial numbers, vintage, volume, and retirement dat
When a renewable‑energy certificate (REC, GO, I‑REC, etc.) is permanently taken out of circulation, the registry issues a cancellation statement. It:
-
Confirms the unique serial numbers, technology, and vintage of the certificates.
-
Shows the date, quantity (MWh), and the organisation on whose behalf the certificates were cancelled.
-
Serves as the audit‑grade proof that no one else can claim the same renewable electricity.
In short, it’s your receipt that the environmental benefit of those certificates now belongs exclusively to you.
