2010 Showerheads Review
The 2010 Review of Showerheads in the Energy Savings Scheme recommended a number of amendments to the Energy Savings Scheme Rule. The key changes were to Table 4 of the Rule, to:
- Make only ultra low flow (6 litres per minute or less) showerheads eligible.
- Set a maximum of three showerhead replacements per household.
- Change the Default Savings Factor (DSF) for showerhead replacement activities to:
- 1.9 megawatt hours of electricity savings where a showerhead is replaced with an ultra low flow showerhead that is connected to an electric resistance water heater in residential or commercial premises
- 1.1 megawatt hours of electricity savings where a showerhead is replaced with an ultra low flow showerhead that is connected to an electric-boosted solar or heat pump water heater in residential or commercial premises
- 1.3 megawatt hours of electricity savings where an ultra low flow showerhead is sold to the Energy Saver (which assumes that the type of water heater to which the showerhead will be connected to is unknown), with a Sales Discount Factor of 0.9 to apply.
In light of these recommendations, the Energy Savings Scheme Rule of 2009 was amended. Further minor technical amendments to the Rule were made to:
- set a maximum number of showerhead replacements at a residential address so as to allow IPART to enforce the recommendations of the Review;
- ensure the Power Factor Correction (PFC) Energy Savings formula calculates the energy savings from PFC activities for the intended deemed lifetime of ten years not one year.
These changes were published in the NSW Government Gazette on Friday 24 December 2010.
The amended Rule was also updated for name changes, clarity and consistency, and to make minor typographical corrections. Refrigerators and freezers tables were updated to reflect changes in star ratings.

Consultation on energy savings measures for the Scheme
Input into the Energy Savings Scheme Rule was sought through a request for ideas in January 2009, at a Workshop on 3 April 2009 and through a public submission process on a draft version of the Rule in May-June 2009.
A half-day workshop was held on the morning of Friday 3 April 2009 at the Sydney Masonic Centre. The workshop provided an opportunity for further stakeholder input into the development of energy efficiency measures to be included in the Scheme, and in particular on development of Default Abatement Factors that will be included in the Scheme Rule.

In January 2009 the Department of Water & Energy requested ideas for energy efficiency measures to be included in the Scheme, including suggestions of ways to improve upon the current energy efficiency provisions in the GGAS Demand Side Abatement Rule. It was requested that all suggestions for new activities and their appropriate factors be supported by a robust methodology in order to determine the benefits of the proposed activity.
In developing the rule for the new Scheme, two objectives were to:
- maximise the potential energy savings by maximising the number and types of activities that are eligible;
- minimise the transaction costs to business of delivering these savings, while ensuring the integrity of the Scheme.
Submissions were considered in developing the NSW Government's final design of the Energy Savings Scheme.
Background and previous consultation on the Scheme
Prior to the NSW Government's announcement of the Energy Savings Scheme on 27 February 2009, the Energy Savings Scheme was referred to as the 'NSW Energy Efficiency Trading Scheme' or 'NEET'. Documents and presentations produced prior to the announcement make reference to the previous Scheme name.
A Stakeholder Consultation Forum was conducted by the NSW Government on Friday, 4 July 2008 to start discussions on the design of the Scheme.
Presentations delivered at the forum are available below:

The Department of Environment & Climate Change and the Department of Water & Energy released a Discussion Paper on the NSW Energy Efficiency Trading Scheme (PDF 141 KB) in mid-2008.
An invitation to comment on the design of the Scheme was issued on this website, with a closing date for comments of 6 August 2008.
