ESS Rule

The Energy Savings Scheme Rule (ESS Rule) applies to Accredited Certificate Providers (ACPs) and their energy savings projects. It provides detail about:

  • Eligibility requirements, and
  • Calculation methods for determining the number of energy savings certificates (ESCs) that can be created.

ACPs must understand the ESS Rule. For information on your obligations, refer to Obligations of an ACP.

The current ESS Rule is effective from 30 March 2020. The ESS Rule was amended in September 2020 with the amendments effective immediately. Previous versions of the ESS rule are provided for reference.

ESS Rule change

The Department of Planning, Industry and Environment (DPIE) is responsible for developing the policy behind the ESS and updating the ESS Rule annually. To find out more about how the ESS Rule is updated and how to get involved, please visit the Energy NSW website.

DPIE is currently reviewing the ESS Rule. The key proposals for the 2020-21 ESS Rule change include:

  • updates to existing air conditioner and refrigerated cabinet activity definitions
  • the introduction of new heat pump and solar water heater activities.

More information on the proposed changes to the ESS Rule is available on the Energy NSW website. Consultation on the proposed changes to the ESS Rule has now closed.

We are working with DPIE on implementing the 2020-21 ESS Rule changes. We will publish information on this page to assist you in understanding how the changes impact you and your business, including any new activities, transitional arrangements, and new or amended evidence requirements.

We also update our guidance to reflect the latest version of the ESS Rule. Changes to the ESS Rule may require you to update your processes, documents and systems.

Please refer to the fact sheets below for more information on how changes to the ESS Rule in March 2020 and September 2020 impact you. Where changes applied to a particular calculation method, we have method specific fact sheets which explain transitional arrangements and new or amended evidence requirements.
