Greenhouse and Energy Minimum Standards Act 2012

 

Greenhouse and Energy Minimum Standards (Three Phase Cage Induction Motors) Determination 2018

Purpose and Operation

The Greenhouse and Energy Minimum Standards (Three Phase Cage Induction Motors) Determination 2018 (the Determination) establishes minimum energy efficiency requirements, and associated requirements for conducting tests, for three phase cage induction motors.

This Determination revokes and replaces the Greenhouse and Energy Minimum Standards (Three Phase Cage Induction Motors) Determination 2012 (revoked Determination).

Background

The Greenhouse and Energy Minimum Standards Act 2012 (the Act) established a national framework for regulating the energy efficiency of products supplied or used within Australia, implementing the Council of Australian Governments’ (COAG) commitment to establish national legislation to regulate energy efficiency and labelling standards for appliances and other products. The Act permits the Australian Government to set mandatory minimum efficiency requirements, to drive greater energy efficiency for products that are regulated. The Act also allows the Australian Government to set nationally-consistent labelling requirements, to increase Australians’ awareness of options to improve energy efficiency and reduce energy consumption, costs, and greenhouse gas emissions. The national framework harmonises the regulation of equipment energy efficiency by replacing seven individual state and territory legislative frameworks.

The Determination references International Electrotechnical Commission (IEC) standards that can be purchased from Standards Australia through its current exclusive licensee, SAI Global. The use of these international standards is consistent with the Australian Government’s policy of harmonisation with international standards where appropriate. The Australian Government envisages that the parties most likely to access the referenced documents are members of industry whose products are covered by the Determination. Those parties can readily purchase the standards online at the SAI Global website.

Options for accessing the standards referenced in the Determination without purchasing them are limited, as the standards subscriptions of the National and State libraries do not generally cover international standards. While this is currently the case, the COAG Industry and Skills Council Standards Accessibility Working Group (ISCSA Working Group) continues to work to develop solutions to greater public access of standards beyond their availability in National and State libraries. In April 2018, the ISCSA Working Group reported to relevant COAG Ministers its findings of a detailed investigation into access to Australian standards. Ministers agreed that recommendations on solutions to the longstanding issue of access to and charges for standards be progressed as a matter of priority.

The Determination includes definitions and text extracted from the relevant IEC standards. This makes it possible to determine if a product is covered by (or excluded from) the Determination and the minimum efficiency levels without having to refer to the standards.

The minimum efficiency levels, or energy use requirements, relate to requirements for the minimum allowable energy efficiency of a product. These are referred in the Determination as greenhouse and energy minimum standards (GEMS) level requirements and are generally known as minimum energy performance standards (MEPS). They provide an energy efficiency ‘floor’ for that product type, below which individual models of that product type cannot be sold. The level of the floor can be raised over time, providing a means of raising the average energy efficiency of the product type.

Other regulatory requirements possible under the Act include requirements relating to energy labelling, high efficiency levels, product performance, and the impact of the product on the environment or the health of human beings. High efficiency levels and energy labelling requirements are set in this Determination. High efficiency level requirements allow suppliers or manufacturers to differentiate more efficient products in the market where the product does not carry an energy rating label, provided they meet a specified efficiency benchmark over and above the nominated GEMS level requirements. For three phase cage induction motors, specific information must be marked on the motor to ensure that consumers can easily identify a product’s specifications.

This Determination is a replacement determination and it makes a series of changes to the requirements applicable to electric motors. These changes are listed below:

·         The testing requirements have been updated to only refer to a single test standard – namely the IEC 60034-2-1 Ed. 2.0 standard. This international test standard was published since the revoked Determination was made. Suppliers of motors will need to test and register their products in accordance with the new standard for the purposes of the Act. When testing the energy efficiency of equipment and appliances, the Australian Government’s preference is to use internationally-recognised and adopted test standards, where appropriate. Accordingly, regionally-specific Australian/New Zealand standards are no longer referenced in this Determination. Referencing a single internationally-recognised test standard removes unnecessary regulatory burden on suppliers and also simplifies administrative arrangements.

·         The Determination now includes tables that specify minimum efficiency levels and high efficiency level requirements. Previously, these requirements were contained in a separate Australian/New Zealand standard (AS/NZS 1359.5:2004) which was referenced in the revoked Determination. This change improves accessibility because suppliers and other interested parties no longer need to purchase a separate standard to determine these requirements.

·         There are relatively minor changes to the minimum efficiency levels to align GEMS level requirements with International Efficiency 2 (IE2) levels (in the IEC framework) and similar small changes to the high efficiency levels that align them with IE3 levels. These minor changes align Australian requirements with international standards, while effectively maintaining the minimum efficiency levels from the revoked Determination. While the overwhelming majority of motors registrations are not affected by these changes, a few registrations are affected as detailed at Schedule 1. Affected models no longer meet minimum efficiency requirements and no further imports of these models can be made after the Determination comes into force. Existing stock will able to be supplied until exhausted.

·         Efficiency levels are now included for 60 Hz motors. The motors were covered by the revoked Determination but were assessed against 50 Hz efficiency levels. This addition means that the efficiency of 60 Hz motors will now be assessed consistent with the IEC framework.

·         A ‘family of models’ arrangement consistent with determinations for other GEMS products is being introduced. This enables models with the same specified characteristics to be covered by a single registration.

·         The Determination introduces specific procedures to test the totally enclosed air over type of motors. The test procedure in the revoked Determination did not replicate real-life operating conditions for these motors which resulted in their energy efficiency performance being worse under test than it actually was when installed.

Authority

Under subsection 23(1) of the Act the Minister may, by legislative instrument, make a determination (a GEMS determination) that specifies one or more classes of products if the products in those classes use energy or affect the amount of energy used by other products. A GEMS determination is the vehicle by which energy efficiency requirements (GEMS level requirements), energy labelling requirements (GEMS labelling requirements), and other requirements for a product class are established.

Section 35 of the Act allows a Minister to make replacement determinations through revoking the previous determination and making a new determination to replace the revoked determination. The new determination can specify the new requirements and retain any relevant existing requirements from the revoked determination. The revoked determination ceases to be in force immediately before the replacement determination comes into force.

Under section 36 of the Act, a replacement determination must specify whether it affects the registration of models of GEMS products. Under subsection 36(2) of the Act, if a replacement determination does not specify that it affects a model’s registration, the model is taken to be registered against the replacement determination.  If a replacement determination specifies that it affects a model’s registration, then under paragraph 48(2)(c)of the Act, the model’s registration ceases to be in force from the time the replacement determination comes into force (or the beginning of the day a registration of the model against the replacement determination comes into force, whichever is the earlier).

Under section 25 of the Act, the GEMS level requirements specified in a GEMS determination may be:

·         requirements relating to one or more of the following:

o   the amount of energy used in operating products in the relevant product classes;

o   the amount of greenhouse gases resulting from operating products in the relevant product class;

o   the effect of those products on the amount of energy used by operating other products; and

·         requirements for conducting tests in relation to products in the relevant product class in order to determine whether the products meet the specified requirements.

Under section 26 of the Act, the GEMS labelling requirements for a product class specified in a GEMS determination are:  

·         requirements relating to the information that must be communicated in connection with supplying or offering to supply products in the relevant product class;

·         requirements relating to the manner in which that information must be communicated; and

·         requirements for conducting tests in relation to products in the relevant product class in order to determine whether the products meet the specified requirements.

Under section 27 of the Act, other requirements that may be specified in a GEMS determination are:

·         requirements for products in the relevant product class to meet a specified level (the high efficiency level) at a particular time;

·         requirements relating to the performance of products in the relevant product class;

·         requirements relating to the impact of products in that product class on the environment or on the health of human beings;

·         requirements for conducting tests in relation to products in the relevant product class in order to determine whether the products meet the specified requirements; and

·         requirements of a kind specified in the regulations for the purposes of that paragraph.

 

Consultation

The Australian Government has consulted with industry stakeholders and the New Zealand Energy Efficiency and Conservation Authority. In 2012, a stakeholder consultation process commenced that examined the energy efficiency regulatory arrangements applicable to three phase cage induction motors. In 2013, a motors product profile document was published and industry consultations were undertaken. Stakeholders called for the:

·         adoption of an internationally-recognised test standard;

·         alignment of Australia’s minimum efficiency levels with recognised international efficiency levels;

·         adoption of an appropriate test standard for totally enclosed air over motors; and

·         adoption of the ‘family of models’ registration facility.

To address these issues, a draft Determination was developed with input from stakeholders including key industry representatives. In March 2018, the Australian Government released an exposure draft of the Determination and invited comments. No submissions were received by the closing date.

Regulatory Impact

The Office of Best Practice Regulation (OBPR) was consulted regarding the proposed changes and advised that ‘…. the relatively limited impact of this proposal on industry means that it falls below the threshold required for the preparation of a regulation impact statement (RIS). As such, the OBPR advises that it would be consistent with the COAG RIS requirements if a RIS were not prepared for this matter’ (OBPR Ref. No. 18024).

Details of the Determination are set out at Attachment A and a statement of compatibility with human rights for the purposes of Part 3 of the Human Rights (Parliamentary Scrutiny) Act 2011 is set out at Attachment B.


Attachment A

Details of the Determination

PART 1—PRELIMINARY

Section 1 – Name

This section sets out the title of the Determination.

 

Section 2 – Commencement, revocation and replacement

This section provides that the Determination commences and comes into force six months after it is registered.

 

It also provides that the Determination revokes and replaces the revoked Determination, being the Greenhouse and Energy Minimum Standards (Three Phase Cage Induction Motors) Determination 2012.

 

Section 3 – Authority

This section identifies the sections of the Act which authorise the Minister to make the Determination.

 

Section 4 – Definitions—standards referred to in this Determination

Section 4 lists the standards referred to in the Determination. While the revoked Determination referenced several alternative test standards, the Determination now only references the IEC 60034-2-1 Ed. 2.0 test standard. Several other IEC standards that support the test standard are also referenced. They are:

·      IEC 60034-1 Ed. 13.0, which specifies the rating and performance characteristics of motors.

·      IEC 60034-30-1 Ed. 1.0, which specifies the efficiency classes and levels for motors.

·      IEC 60050-411 Ed. 2.0, which defines the vocabulary used in the above standards.

 

Section 5 – Definitions—other expressions used in this Determination

This section sets out definitions for key terms, including technical terms, used in the Determination. The definitions provided include:

·      “cage induction motor” which means an induction motor with secondary cage (squirrel cage) winding(s) that consist of a number of conducting bars that have their extremities connected by conducting rings or plates at each end;

·      “rated” quantity or value which means a quantity or value assigned, generally by a manufacturer, for a specified operating condition of a machine; and

·      “S2 – short-time duty” which means operation at constant load for a given time, less than that required to reach thermal equilibrium, followed by a time de‑energised and at rest of sufficient duration to re-establish machine temperatures within 2 Kelvin of the coolant temperature.

 

Section 6 – Applicable definitions and applicable versions of standards and documents incorporated into standards

Section 6 provides guidance for interpreting certain aspects of the Determination.

 

Subsection 6(1)

 

This subsection sets out the order in which priority should be taken in the interpretation of relevant provisions if there are any inconsistencies between the Act, this Determination and the standards.

 

Subsection 6(2)

 

The purpose of this subsection is to make clear that the applicable version of any relevant standard, or other relevant document that is referred to in a standard, is the version that is current on the date that the Determination was made.

 

Section 7 – Families of models

Section 28 of the Act provides that a GEMS determination must specify, for each product class covered by the determination, the circumstances in which two or more models in that product class are in the same family of models.

 

This Determination introduces family of models circumstances for motors for the first time. This is a new feature that was not included in the revoked Determination.

 

Subsection 7(1)

 

This subsection specifies that the circumstances in which two or more models of motors covered by this Determination may be in the same family of models are when they are members of a family declared to the GEMS Regulator and the requirements set out in subsections (2) to (4) are satisfied.

 

Subsection 7(2)

 

This subsection specifies the characteristics of motors that must be the same in order for them to be in the same family of models (including, for example: brand, frame size, number of poles, and rated output power).

 

Subsection 7(3)

 

The purpose of this subsection is to ensure that each model in a family of models has an equivalent electrical design, by requiring that the product of each motor’s rated voltage and rated current must be the same.

 


Subsection 7(4)

 

This subsection limits the size of a family to no more than 10 models.

 

Section 8 – Product category

Section 29 of the Act requires that a GEMS determination specify whether the products it covers are category A or category B products. Category B products are subject to higher penalties than category A products for certain offences under the Act, on the basis that category B products have a high impact on energy use or greenhouse gas production.

 

This section specifies that motors covered by the Determination are category A products. This is unchanged from the revoked Determination.

 

Section 9 – Registrations affected by this Determination

Section 36 of the Act requires that a GEMS replacement determination must specify whether it affects the registration of: all models, specified models, or no models, of GEMS products that were covered by the revoked Determination.

 

This section provides that the registration of models made under the revoked Determination specified in Schedule 1 of the Determination are affected. The effect of this is that the specified models are no longer registered against a GEMS determination from the date this Determination comes into force. Registrations not specified in Schedule 1 are taken to be registered against this Determination from the date it comes into force.

 

PART 2 – PRODUCTS COVERED BY DETERMINATION

Section 10 – Purpose of Part

This section notes that for subsections 23(1) and (2) of the Act, Part 2 of the Determination specifies which classes of motors are covered by the Determination and which classes of motors are not covered by the Determination.

 

Section 11 – Classes of products that are covered by this Determination

Subsection 11(1)

 

This subsection sets out the scope of the Determination with respect to the class of products that it covers. It provides that the Determination covers three phase cage induction motors with: an output power rating from 0.73 kilowatts to less than 185 kilowatts, with either 2-pole, 4-pole, 6-pole or 8-pole configurations, and with a rated voltage of up to 1100 volts alternating current.

 

While pole configuration was not explicitly articulated in the equivalent section of the revoked Determination, the efficiency tables in AS/NZS 1359.5:2004 that it incorporated by reference set efficiency requirements only for 2-pole, 4-pole, 6-pole, and 8-pole motors. Pole configuration is therefore included in this subsection for clarity, but the scope of this Determination is unchanged from the revoked Determination.

 

Subsection 11(2)

 

This subsection specifies that the three phase cage induction motors covered by the Determination form a single product class.

 

Section 12 – Classes of products that are not covered by this Determination

This section sets out product classes that are not covered by the Determination. They are the same product classes that were excluded in the revoked Determination. They are:

a)      a submersible (sealed) motor specifically designed to operate wholly immersed in a liquid. This exclusion does not cover motors that may be designed to only withstand temporary inundation;

b)      a motor that shares common components (apart from connectors) with the driven unit and cannot operate as a motor if separated from the driven unit, even if a temporary end shield or a drive-end bearing is fitted. An example of such a motor could be a motor constructed on the same shaft as a compressor for an air-conditioning unit;

c)      a motor that can run at two or more discrete speeds by using switchgear to reconfigure the connection of the motor’s winding or windings to the supply, also known as a “multi-speed motor”. This exclusion does not cover motors that run at different speeds by means of a variable voltage or variable frequency controller;

d)     a motor that is only used for short-time duty cycle applications which have a duty type rating of S2 – short-time duty. Examples include motors used for vehicle hoists, roller doors and cranes;

e)      a rewound motor that has had its insulated winding or windings replaced and the supplier has not made any claim that the rewound motor meets a GEMS level requirement;

f)       a motor that is supplied exclusively to third parties who will incorporate the motors into equipment that will be exported to a country other than Australia or New Zealand;

g)      a high slip motor designed primarily to provide torque, often at or near 100 per cent slip. Such a motor is known as a “torque motor”.

 

PART 3 – GEMS LEVEL REQUIREMENTS

Section 13 – Purpose of Part

Section 13 notes that Part 3 of the Determination specifies GEMS level requirements for energy use and greenhouse gas production for motors covered by the Determination, including requirements for conducting tests in order to demonstrate compliance with the energy use requirements under section 25 of the Act.

 


Section 14 – GEMS level requirements

Subsection 14(1)

 

This subsection provides that the efficiency of a motor covered by this Determination must not be less than the relevant value set out in Table 2 of Schedule 2 to this Determination. Methods are also specified for working out the relevant value if the rated output power of the motor falls between the rated output power values identified in Table 2.

 

Subsection 14(2)

 

This subsection specifies that the requirements specified in subsection (1) are set in relation to 50Hz and 60Hz motors in 2-pole, 4-pole, 6-pole, or 8-pole configurations.

 

Section 15 – Conducting tests

Subsection 15(1)

 

This subsection specifies that the general requirements for conducting tests are the requirements mentioned in subclause 6.1.3 of IEC 60034-2-1 Ed. 2.0 (Method 2-1-1B – Summation of losses, additional load losses according to the method of residual loss). This is a change from the revoked Determination and adopts the internationally-recognised test standard for motors. This change removes unnecessary regulatory burden on suppliers and also simplifies administrative arrangements.

 

Subsection 15(2)

 

This subsection specifies special test conditions, in addition to the general testing requirements specified in subsection (1), for testing totally enclosed air over motors defined at subsection (4). This change from the revoked Determination addresses stakeholder concerns that this type of motor was tested under conditions that did not replicate real-world applications and therefore penalised their energy efficiency performance. The new requirements mean that these types of motors are now tested in an appropriate manner.

 

Subsection 15(3)

 

This subsection details the specific measurement requirements for tests conducted according to subsection (2).

 

Subsection 15(4)

 

This subsection defines a “totally enclosed air over motor” as a frame surface cooled machine, the exterior of which is cooled by a ventilating means external to the motor, for example by a fan.


PART 4 – GEMS LABELLING REQUIREMENTS

Section 16 – Purpose of Part

Section 16 notes that Part 4 of the Determination specifies GEMS labelling requirements for motors covered by the Determination in accordance with section 26 of the Act.

 

Section 17 – GEMS labelling requirements

Section 17 specifies that labelling and communication requirements are the requirements mentioned in clause 10 of IEC 60034-1 (Rating plates). These requirements concern information that must be marked on the rating plate of the product. This information is relevant to both users of motors, enabling the selection of more efficient motors, and for the GEMS Regulator when undertaking compliance activities.

 

The minimum requirements for items on the rating plate include the:

a)      manufacturer’s name or mark;

b)      manufacturer’s serial number, or identification mark;

c)      rated output(s) or range of rated output;

d)     class(es) of rating of the machine if designed for other than rating for continuous running duty S1;

e)      rated frequency or range of rated frequencies; and

f)       the efficiency class (IE code) and the rated efficiency

 

Section 18 – Conducting tests

This section specifies that the requirements for conducting tests for the purposes of the information that must be conveyed on a product’s rating plate are the same as those set out in section 15 of the Determination in relation to the GEMS level requirements.

 

Section 19 – Impact of replacement determination

Section 19 provides a mechanism, in the event that this Determination is replaced in the future, to allow a transitional labelling provision to be specified in that replacement Determination (the new Determination) with the effect that complying with its requirements will be taken to be compliance with the labelling requirements of this Determination. This is to prevent the situation arising, in circumstances where a registrant chooses to register to the new Determination between the time it is made and when it comes into force (as allowed by section 44 of the Act), of a product needing to comply with the labelling requirements of both Determinations.

 


PART 5 – OTHER REQUIREMENTS

Section 20 – Purpose of Part

Section 20 notes that Part 5 of the Determination specifies other requirements for motors covered by the Determination in accordance with section 27 of the Act.

 

These other requirements are in relation to the high efficiency level for motors covered by the Determination, including requirements for conducting tests in order to demonstrate compliance with high efficiency level requirements.

 

The “high efficiency” designation can be used for the most efficient product models, assisting businesses to promote, and consumers to select, highly efficient products. Products do not need to meet the high efficiency level but those which do are entitled to promote the product as a high efficiency motor.

 

Section 21 – High efficiency level

Subsection 21(1)

 

This subsection provides that a motor covered by this Determination meets the high efficiency level if its efficiency is not less than the value relevant to its rated output power set out in Table 3 of Schedule 2 to this Determination. Methods are also specified for working out the relevant value if the rated output power of the motor falls between the rated output power values identified in Table 3.

 

Subsection 21(2)

 

Subsection 21(2) specifies that a motor may be designated as “high efficiency” only if it meets the high efficiency level.

 

Subsection 21(3)

 

This subsection specifies that the requirements specified in subsection (1) are set in relation to 50Hz and 60Hz motors in 2-pole, 4-pole, 6-pole or 8-pole configurations.

 

Section 22 – Conducting tests

This subsection specifies that the requirements for conducting tests for the purposes of the high efficiency levels are the same as those set out in section 15 of the Determination in relation to the GEMS level requirements.

 


Schedule 1—Registrations affected by this Determination

Schedule 1 lists the models that are specified for the purposes of section 9.

 

Schedule 2—Minimum efficiency levels

This Schedule provides tables that specify the minimum efficiency levels that types of motors need to meet to satisfy the relevant requirements. Table 2 specifies GEMS level requirements and Table 3 specifies high efficiency level requirements. These tables were previously contained in a separate Australian/New Zealand standard (AS/NZS 1359.5:2004) that was referenced by the revoked Determination. This addition improves accessibility because suppliers no longer a need to purchase a separate standard to determine these requirements.

 

The tables also provide minimum efficiency values for 60 Hz motors. The efficiency level tables referenced by the revoked Determination only specified levels for 50 Hz motors. The tables now include efficiency levels for 60 Hz motors that were in scope of the revoked Determination but were assessed against the 50 Hz tables. This addition means that the efficiency of 60 Hz motors will now be assessed consistent with the IEC framework.

 

There are relatively minor differences in the minimum efficiency levels in these tables compared to the tables in AS/NZS 1359.5:2004, in order to align GEMS level requirements with International Efficiency 2 (IE2) levels (in the IEC framework). There are similar small changes to the high efficiency levels that align them with IE3 levels. These minor changes align Australian requirements with international standards, while effectively maintaining the minimum efficiency levels from the revoked Determination.
