ESS Rule change

The Department of Planning and Environment (DPE) 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.

The key proposals for the recent ESS Rule change that commenced on 28 February 2022 included:

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

We have updated 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.

The information on this page can assist you in understanding how the changes impact you and your business, including any new activities, transitional arrangements, and new or amended evidence requirements.
