About US-RECs Registries
Certificate tracking systems manage Renewable Energy Certificates (RECs) and guarantee their exclusive ownership by a single organization. These systems handle the issuance and retirement of certificates, fostering transparency and legitimacy while preventing any risk of double counting. Typically, these tracking systems take the form of electronic databases that record essential details regarding each MWh of renewable energy generation within specific geographical regions of the US and Canada.
