Overview of E3 Program
• E3 = Equipment Energy Efficiency
• Jointly run by Australian federal,
state & territory governments & NZ
– Relies on national legislation GEMS -implemented October
2012 in Australia, and NZ
• 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
• 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 converterfed 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
• 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
• 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
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)
