This Part provides for the creation, trading and extinguishing of renewable energy certificates. The certificates are used to avoid or reduce the amount of renewable energy shortfall charge that liable entities who acquire electricity have to pay. The liable entities will generally acquire the certificates by purchasing them. The certificates are created by people who generate power from accredited power stations using renewable energy sources where the amount generated exceeds the relevant 1997 eligible renewable power base line. The certificates are also created for approved installations of solar hot water heaters. A person needs to be registered under Division 2 before they can create a certificate. A power station needs to be accredited under Division 3 before a certificate can be issued in relation to power generated by it. A certificate must be registered when it is created. Every transfer of the certificate must also be registered. When a certificate has been surrendered by a liable party, it ceases to be valid.
