Overview of E3 Program

• • • • E3 =






fficiency Jointly run by Australian federal, state & territory governments & NZ – Relies on national legislation GEMS -implemented October 2012 in Australia, and NZ legislation Mandatory measures: MEPS & the Energy Rating Label Voluntary measures: voluntary labelling, HEPS, training and information, and support to promote best available products

GEMS legislation

Greenhouse & Energy Minimum Standards (GEMS) Act 2012

promotes the development and adoption of products to reduce energy use, reduce energy costs to consumers and produce fewer greenhouse gases.

Uses Ministerial Determinations (GEMS Determinations) to apply greenhouse and energy minimum standards (GEMS) to products that use energy, or affect the energy used by another product.

• • GEMS regulates ‘supply’ (including supply of products by way of sale, exchange, gift, lease, loan, hire or hire-purchase) and ‘offer to supply’, and ‘use for a commercial purpose’. 1 Oct, 2012 - GEMS creates a national framework for E3 by replacing seven overlapping pieces of state legislation.

Current situation

• • • • • • MEPS for electric motors began in 2001 Stringency increased in 2006 MEPS scope covers alternating current, three phase cage induction motors, up to 1100V, 0.73 to <185 kW output power, manufactured in or imported into Australia or New Zealand.

High MEPS compliance rate Other countries are regulating higher MEPS levels Better technologies are on the market

Current situation

• • • GEMS Determination for electric motors specifies two sets of MEPS levels and associated test methods (Methods A and B).

There was no international agreement on a test method when AS/NZS 1359.5:2004 was published.

Method A has since achieved international agreement as a more realistic measurement procedure. It is equivalent to: The ‘preferred method’ in the revised international test standard IEC 60034-2-1 Ed 2.0, due to be published in June 2014 United States test standard IEEE 112, Method B

Work to date

• • • Since 2009, E3 has been actively contributing to the development of international testing and performance standards for electric motor energy efficiency Andrew Baghurst has represented Australia on several International Electrotechnical Committee (IEC) standards committees Australia has participated actively in the IEA 4E EMSA (International Energy Agency Energy Efficient End-use Equipment Electric Motor Systems Annex), leading the EMSA ‘Testing’ task: Building a global ‘Testing Centres Network’ of approx 80 members from 50 laboratories in 30 countries, engaging in annual workshops Collaborating with Swiss laboratory EPF-Lausanne to develop test procedures for converter-fed motors

Work to date

• Australia’s participation in EMSA and IEC standards committees has resulted in three new international publications since October 2013: performance standard IEC 60034-30-1 Efficiency classes of

line operated AC motors (IE code)

technical specification IEC TS 60034-2-3 Specific test

methods for determining losses and efficiency of converter-

fed AC induction motors, and revised test standard IEC 60034-2-1 Ed 2.0 Standard

methods for determining losses and efficiency from tests

(excluding machines for traction vehicles) (due for publication June 2014)

Work to date

• • • • • • Customs Alerts Australian Industry Group raised concerns that non-MEPS compliant motors are being imported inside machinery and equipment AI Group requested that Department of Industry work with Australian Customs Message alerts are currently activated when equipment that may contain motors is imported The initial approach taken by the Compliance team is to educate the people importing machinery and equipment that may contain motors which may be covered by GEMS Determination requirements.

6 month trial running from 2 April 2014 until 2 October 2014.

Data will be analysed

Work to date

Consultation on Product Profile: Electric

Motors - Oct 2013

• Feedback generally supported harmonising with international performance and test standards, and EU regulations ( ie. scope, MEPS levels, tolerances).

Work to date

• • Feedback on the Product Profile showed industry support for the adoption of IEC test standard 60034-2-1 Ed 2.0 because of: Harmonisation: Electric motors are imported and Aust/NZ are small markets globally. Confusion: Use of different test methods with different MEPS levels

Electric motors workplan

• Adopt the ‘preferred method’ in the international test standard IEC 60034-2-1 Ed 2.0 (to be published June 2014) 1. Develop a proposal to revise Motors GEMS Determination 2. Formal consultation on regulation impact statement (RIS) 3. Decision RIS 4. Implementation of revised GEMS Determination

Electric motors workplan

• • Other features requested by stakeholders include: ‘Family of models’ registration option Aligning with EU regulations and IEC performance standard, such as scope, exclusions, tolerances Referencing a test procedure for totally enclosed air-over (TEAO) motors Specifying voltages for motor testing for registration and check-testing purposes These features will also be considered in the first amendment to the GEMS Determination

Future work

Examination of improved energy efficiency opportunities Any work will be subject to thorough cost benefit analysis and consultation on a range of policy options such as: • • Increasing MEPS levels to IE3 (currently Australian HEPS levels) Scope extensions could be based on the international performance standard IEC 60034-30-1: All motors rated for on-line operation, 185 - 1,000 kW (includes LSPM and 3-phase induction motors) All motors rated for on-line operation, 0.12 to 0.73 kW (includes LSPM, single- and 3-phase induction motors)
