Energy savings certificates

Common questions

Q. What is an energy savings certificate, or ESC?

An energy savings certificate, or ESC (pronounced "esky"), represents one notional Megawatt hour (MWh) of energy.

Accredited Certificate Providers can implement energy saving projects and create ESCs representing the energy savings from the project.  These certificates can be traded and sold to Scheme Participants who have an obligation to meet energy savings targets each year through the surrender of certificates or the paying of a penalty.

See Certificate market

Q. What is a certificate worth?

A: The price of a certificate varies depending on supply and demand.

If a Scheme Participant does not meet the annual target for energy savings, they are required to pay a penalty. The penalty rate acts as a certificate price ceiling. There is no minimum price for ESCs.

IPART is the Scheme Administrator only and is not involved in the sale or pricing of ESCs and cannot provide any further information in this regard.

Q. How are certificates created and registered?

See    Creating certificates.

Q. How do I sell my certificates and who will buy them?

A: Scheme Participants have an obligation to meet energy saving targets under the ESS and can meet their targets by either surrendering certificates or paying a penalty.  

IPART manages the Registry where certificates are created and transferred, but is not involved in the actual sale or trading of certificates.

The contracts that Accredited Certificate Providers enter to sell certificates occur independently of IPART and outside of the ESS Registry.
