NSW ESS 2017 Rule Change

The NSW Government has completed its annual review of the ESS Rule. Amendments will take effect from the 28th of April 2017. For the IPART summary of changes, click here. NCBA has highlighted the following:

  1. A/C Multiplier

Implementations completed after the 28th of April 2017 will be subject to a new multiplier applied to air conditioned spaces. The new A/C multiplier is reduced from 1.3 to 1.07 for all projects (other than Data Centres and Refrigerated rooms) that are ‘air-conditioned during normal operating hours by a refrigerant-based air-conditioner’. Implementations completed before the 28th of April 2017 must be registered on or before June 30 2017 in order to take advantage of the old Rule multiplier. If you have further questions, please contact your NCBA Account Manager.

  1. $5 Minimum Co-Payment

The co-payment clause in the ESS Rule was amended so that ‘energy savings may only be calculated if the purchaser has paid a net minimum of $5 per mega-watt hour of electricity saved, excluding GST’. Therefore, the minimum payment must occur before any Energy Savings Certificates (ESCs) can be registered and evidence provided accordingly. For further clarification, please contact your NCBA Compliance Manager.

  1. Project Impact Assessment: Measurement and Verification (PIAM+V)

There have been a variety of amendments within the PIAM+V space, including a new clause catering for the calculation of energy savings across for multiple sites, the Sampling Method. To learn more about this form of certificate creation or to see if your project is eligible, please call David Joseph or Jo Hoatson on (02) 9939 5559.

  1. ACT Energy Efficiency Improvement Scheme (EEIS)

The latest ESS Rule Change has additional amendments to accommodate the possible integration of the ACT EEIS with the NSW ESS. This is a positive step in the harmonisation of the various Energy Efficiency Schemes across Australia.

  1. Other Amendments

Other changes to the rule include amendments to the energy savings factors under the Home Energy Efficiency Retrofit (HHER) method, inclusion of Nabers-rated Hospitals under the Nabers method and inclusion of gas-fired boilers and heaters as well as amended hours for liquid chilling packages and high efficiency air conditioners under the High Efficiency Appliances for Businesses (HEAB) sub-method.
