The Office of Energy and Climate Change within NSW Treasury is responsible for developing the policy behind the ESS and updating the ESS Rule annually or at other times as required. To find out more about how the ESS Rule is updated and how to get involved, please visit the Energy NSW website.

The most recent ESS Rule Change commenced on 1 August 2022 and was an emergency change to address undesirable practices in relation to refrigerated cabinet activities.  

The key changes for the recent ESS Rule change that commenced on 1 August 2022 included:

  • Introduction of a co-payment requirement for the installation of refrigerated cabinets
  • Splitting of baselines for new versus replacement equipment (activities F1.1 and F1.2)
  • Clarification that activities can only be done in non-residential buildings

We have published a Fact Sheet to provide information on these changes which can be accessed by the link below.
