Frequently Asked Questions

Energy savings certificates

What is an energy savings certificate, or ESC?

Energy Savings Certificates, or ESCs (pronounced "esky"), are tradeable certificates created under the Energy Savings Scheme.

ESCs represent energy savings arising from a recognised energy saving activity. One ESC represents one notional Megawatt hour (MWh) of energy saved.

Only Accredited Certificate Providers (ACPs) can create ESCs. ACPs can only create ESCs from recognised energy savings activities for which they are accredited for.

Scheme Participants purchase ESCs and surrender them to the Scheme Regulator to meet obligations they have under the Scheme.

More information about how ESCs are registered, transferred and surrendered is available on the ESS Registry and ESS Portal page.
