3A. Requirements for Transmission Connected Generating Systems
Explanatory Note Section 3A.1 sets out the general requirement for a Market Participant responsible for a Transmission Connected Generating System to comply with Chapter 3A and Appendix 12 unless it is exempted under section 3A.3. Chapter 3A will only apply to generating works connected to a transmission system. |
|---|
3A.1. General
Explanatory Note Clause 3A.1.1 is intended to be a civil penalty provision. |
|---|
3A.1.1. A Market Participant must comply with each Registered Generator
Performance Standard for a Transmission Connected Generating System from the time that they:
\(a\) are issued an Approval to Generate Notification; or
\(b\) cease to be an Existing Transmission Connected Generating System as detailed in clause 1.39.13.
3A.1.2. If there is any inconsistency between the provisions of these
WEM Rules (including Appendix 12) and the Technical Rules of the relevant Network Operator, the provisions of these WEM Rules prevail to the extent of the inconsistency.
3A.1.3. A Network Operator and AEMO must document a process by which
they will provide each other with information, consult with each other, or reach agreement in respect of the matters in this Chapter 3A and Appendix 12 including:
\(a\) the requirements for, and manner in which, they will consult with each other;
\(b\) the format, form and manner in which any information must be provided; and
\(c\) where these WEM Rules do not provide a timeframe for the provision of the information, the time by which such information must be provided.
Explanatory Note Unregistered generators serving Intermittent Load are subject to Generator Performance Standards. Clause 3A.1.4 clarifies the responsible Market Participant. |
|---|
3A.1.4. Where the person who owns, controls, or operates a Facility
containing an unregistered Energy Producing System supplying an Intermittent Load, that is and continues to be deemed to be an Intermittent Load under clause 1.48.2, is exempted from the requirement in clause 2.30B.8 to make a new application under clause 2.30B.5 for the Load to be treated as an Intermittent Load based on clause 2.30B.8A, the person's Intermediary is responsible for that Transmission Connected Generating System.
Explanatory Note Clause 3A.1.5 is added to provide guidance to Participants on how AEMO and Western Power will determine the maximum temperature for a Transmission Connected Generating System under Appendix 12. |
|---|
3A.1.5. AEMO must:
\(a\) in consultation with the Network Operator, prepare guidelines on how AEMO determines the maximum temperature as defined in Appendix 12; and
\(b\) publish those guidelines on the WEM Website.
Explanatory Note Clause 3A.1.6 is added to require AEMO or Western Power, as applicable, to undertake a public consultation process to obtain stakeholder feedback and to respond to the issues raised in submissions received. |
|---|
3A.1.6. In developing, amending or replacing a guideline in accordance
with clauses 3A.1.5, 3A.4.4 or 3A.13.2, AEMO or the Network Operator, as applicable, must:
\(a\) publish, together with the proposed guideline, or the amendment or replacement of it, as applicable, a call for submissions, and the closing date for submissions must not be less than 15 Business Days from the date the proposed or revised guideline is published; and
\(b\) publish, together with the final guideline, a summary of the submissions received and the response of AEMO or the Network Operator, as applicable, to the issues raised in those submissions.
Explanatory Note Section 3A.2 sets out the general requirements on Market Participants to provide relevant information. Section 3A.2 includes an obligation on a Market Participant to ensure that its generation system model (required under Appendix 12) complies with the WEM Procedure developed by the Network Operator. If the WEM Procedure is amended then the Market Participant must ensure that its generation system model complies with the amended WEM Procedure. When a Network Operator amends the WEM Procedure it will also specify a time by when the Market Participant must comply with the amended WEM Procedure. |
|---|
3A.2. General Requirements to Provide Relevant Information
3A.2.1. A Market Participant responsible for a Transmission Connected
Generating System must provide all data and information reasonably required by a Network Operator or AEMO under this Chapter 3A and relevant provisions under Appendix 12 to assess the impact of a Transmission Connected Generating System on the performance and security of the transmission system and distribution system.
3A.2.2. A Market Participant responsible for a Transmission Connected
Generating System must ensure that the generation system model referred to in Appendix 12 complies with the requirements specified in the WEM Procedure of the relevant Network Operator referred to in clause 3A.4.2.
3A.2.3. Where the requirements for the generation system model are
amended in the WEM Procedure referred to in clause 3A.4.2, a Market Participant responsible for a Transmission Connected Generating System must ensure that the generation system model used by the Market Participant complies with the amended requirements within the timeframes specified in the WEM Procedure for compliance with the amended requirements.
Explanatory Note Section 3A.3 sets out a mechanism for a Network Operator to exempt a Transmission Connected Generating System from the requirements of Chapter 3A. The section recognises that the compliance costs would outweigh the benefits of applying the regime to certain generating works, such as smaller generators. The exemption regime will exempt a generating system from section ### 3A.1, section 3A.2, sections 3A.5 to 3A.12 and Appendix 12. An exemption notice may only be revoked where the generating system is undertaking a Relevant Generator Modification. An exempt generating system will still be required to comply with the Technical Rules. |
|---|
3A.3. Exempt Transmission Connected Generating Systems
3A.3.1. A Network Operator may, by written notice, exempt a Market
Participant responsible for a Transmission Connected Generating System from all of the requirements of section 3A.1, section 3A.2, sections
3A.5 to 3A.12 and Appendix 12 in respect of a Transmission Connected
Generating System (Exempt Transmission Connected Generating System) where the Network Operator and AEMO agree that the cost incurred by the Market Participant responsible for the Transmission Connected Generating System to comply with Chapter 3A and Appendix 12 is reasonably likely to outweigh the benefit of requiring the Market Participant to comply having regard to:
\(a\) the potential of the Transmission Connected Generating System to adversely affect Power System Security or Power System Reliability; and
\(b\) the effect the proposed exemption will, if granted, have on other Market Participants.
3A.3.2. An exemption notice issued under clause 3A.3.1 must be provided
to the Market Participant responsible for a Transmission Connected Generating System and the relevant Network Operator must keep a record of each exemption notice issued.
3A.3.3. A Network Operator may revoke an exemption notice issued under
clause 3A.3.1 by written notice to a Market Participant responsible for the Exempt Transmission Connected Generating System where a Relevant Generator Modification is proposed to be undertaken in respect of the Exempt Transmission Connected Generating System.
3A.3.4. Where an exemption notice issued under clause 3A.3.1 is revoked
under clause 3A.3.3, section 3A.14 applies.
3A.3.5. A Network Operator must notify the Economic Regulation Authority
when it issues an exemption notice under clause 3A.3.1 or revokes an exemption notice under clause 3A.3.3.
3A.3.6. The Economic Regulation Authority must publish a list of Exempt
Transmission Connected Generating Systems and update that list when it is notified by a Network Operator under clause 3A.3.5.
Explanatory Note Section 3A.4 sets out general obligations of a Network Operator. It will require a Network Operator to ensure its connection processes are consistent with Chapter 3A. It provides a head of power for a Network Operator to create a WEM Procedure in respect of the requirements for a Market Participant's generation system model. It also creates a head of power for a Network Operator to issue guidelines as to how it will assess generator performance standards. |
|---|
3A.4. General Obligations of a Network Operator
3A.4.1. A Network Operator must ensure its connection process as it
relates to Transmission Connected Generating Systems for which a Market Participant is responsible is consistent with this Chapter 3A.
3A.4.2. A Network Operator must develop and maintain a WEM Procedure
that addresses the requirements of the generation system model referred to section 17 of Appendix 12.
3A.4.3. The WEM Procedure referred to in clause 3A.4.2, must specify the
timeframes by which the Market Participant must ensure that the generation system model referred to in section 17 of Appendix 12, complies with each amended requirement of the generation system model as specified in the WEM Procedure.
Explanatory Note Clause 3A.4.4. is amended to require the network operator to prepare assessment guidelines in consultation with AEMO, and to publish them on its website and to provide guidance for Participants on what information needs to be included in their submissions. |
|---|
3A.4.4. A Network Operator must:
\(a\) prepare guidelines in consultation with AEMO, to provide information to Market Participants as to how the standard or technical level of performance in respect of each Technical Requirement will be assessed, and the information that must be included in submissions for Proposed Generator Performance Standards, for each type of generating unit; and
\(b\) publish those guidelines on its website.
Explanatory Note Section 3A.5 sets out the approval process and negotiation framework for determining generator performance standards for Market Participants wishing to connect generating systems to the transmission network. The applicable standards are set out as Technical Requirements under Appendix 12. For most Technical Requirements, there is an Ideal Generator Performance Standard and a Minimum Generator Performance Standard. The Network Operator must accept a Proposed Generator Performance Standard that meets the Ideal Generator Performance Standard and must reject any proposed standard below the Minimum Generator Performance Standard. Where a Proposed Generator Performance Standard is between the range of minimum and ideal, the generator must adequately justify why it cannot achieve the Ideal Generator Performance Standard. The Network Operator must consult with AEMO on any negotiated standard that it is likely to accept, and is not permitted to accept the standard unless AEMO also agrees. If rejecting a Proposed Generator Performance Standard, the Network Operator and AEMO must provide reasons. A Market Participant may propose a Trigger Event. If an approved Trigger Event occurs then the Market Participant must comply with the conditions of the Trigger Event. Once approved, the generator performance standards for a Transmission Connected Generating System must be recorded on the Generator Register. |
|---|
3A.5. Generator Performance Standards for Transmission Connected
Generating Systems
3A.5.1. Where a Market Participant responsible for generating works
intends to connect those generating works to a transmission system, the Market Participant must submit to the relevant Network Operator, Proposed Generator Performance Standards for the generating works as if the generating works were a Transmission Connected Generating System addressing each Technical Requirement.
3A.5.2. Each Proposed Generator Performance Standard submitted under
clause 3A.5.1 or clause 3A.14.1(a) must meet the Common Requirements and:
\(a\) be equal to or better than the Ideal Generator Performance Standard; or
\(b\) if a Proposed Negotiated Generator Performance Standard is submitted:
i. be no less onerous than the Minimum Performance Standard;
ii. demonstrate any applicable Negotiation Criteria have been met;
iii. meet the requirements of clause 3A.5.5; and
iv. if applicable, meet the requirements of clause 3A.5.6.
3A.5.3. The Network Operator must not approve a Proposed Generator
Performance Standard that does not meet or demonstrate the applicable criteria listed in clause 3A.5.2.
3A.5.4. The Network Operator is not required to consult AEMO and must
approve a Proposed Generator Performance Standard that is equal to or better than the Ideal Generator Performance Standard for a Technical Requirement.
3A.5.5. A Proposed Negotiated Generator Performance Standard must be as
consistent as practicable with the corresponding Ideal Generator Performance Standard for that Technical Requirement, having regard to:
\(a\) the need to protect the Transmission Connected Generating System from damage;
\(b\) power system conditions at the location of the connection or proposed connection; and
\(c\) the commercial and technical feasibility of complying with the Ideal Generator Performance Standard.
3A.5.6. A Proposed Negotiated Generator Performance Standard may include
a Trigger Event which must address:
\(a\) the conditions for determining whether the Trigger Event has occurred;
\(b\) the party responsible for determining whether the Trigger Event has occurred;
\(c\) the actions required to be taken and any revised standard or technical level of performance in respect of a Technical Requirement which must be achieved if the Trigger Event occurs;
\(d\) the maximum timeframe for compliance with any action required to be taken and each revised standard or technical level of performance in respect of a Technical Requirement following the Trigger Event;
\(e\) any requirements to provide information and supporting evidence required by the Network Operator or AEMO to demonstrate that, if the Trigger Event occurs, the actions required will occur and will deliver the agreed outcome and level of performance required by any revised standard or technical level of performance in respect of a Technical Requirement;
\(f\) any testing requirements to verify compliance with each revised standard or technical level of performance in respect of a Technical Requirement; and
\(g\) any requirements necessary to verify that the actions required to be taken have occurred if the Trigger Event occurs.
Explanatory Note Clause 3A.5.7 is intended to be a civil penalty provision. |
|---|
3A.5.7. If a Registered Generator Performance Standard includes a
Trigger Event and the Trigger Event subsequently occurs, the Market Participant responsible for the Transmission Connected Generating System must comply with the requirements of the Trigger Event.
3A.5.8. A Trigger Event contained in a Registered Generator Performance
Standard may be modified by written agreement between the Market Participant responsible for the Transmission Connected Generating System, AEMO and the relevant Network Operator. For the avoidance of doubt, the process that applies to a Proposed Negotiated Generator Performance Standard in this section 3A.5 does not apply to the modification of a Trigger Event contained in a Registered Generator Performance Standard under this clause 3A.5.8.
3A.5.9. If a Market Participant responsible for a Transmission Connected
Generating System submits to the Network Operator a Proposed Negotiated Generator Performance Standard under clause 3A.5.1 or clause 3A.14.1(a), the Market Participant responsible for the Transmission Connected Generating System must provide to the relevant Network Operator:
\(a\) the reasons and supporting evidence why the Market Participant responsible for the Transmission Connected Generating System cannot meet the Ideal Generator Performance Standard; and
\(b\) any information and supporting evidence required by the Network Operator setting out the reasons why the Proposed Negotiated Generator Performance Standard is appropriate, including:
i. how the Proposed Negotiated Generator Performance Standard meets the applicable criteria listed in clause 3A.5.2; and
ii. how the Market Participant responsible for the Transmission Connected Generating System has taken into account each of the matters listed in clause 3A.5.5.
3A.5.10. If, following the receipt of a Proposed Negotiated Generator
Performance Standard and the information and evidence referred to in clause 3A.5.9, the Network Operator reasonably considers it will approve the Proposed Negotiated Generator Performance Standard, the Network Operator, in accordance with the process agreed under clause 3A.1.3, must:
\(a\) provide the information received from the Market Participant responsible for the Transmission Connected Generating System under clause 3A.5.9 to AEMO; and
\(b\) use best endeavours to consult with AEMO within a reasonable timeframe in relation to each Proposed Negotiated Generator Performance Standard.
3A.5.11. AEMO must use best endeavours to respond in a reasonable
timeframe after being consulted in accordance with clause 3A.5.10 and provide a recommendation to the Network Operator whether a Proposed Negotiated Generator Performance Standard should be approved or rejected by the Network Operator, or whether AEMO requires further information to make the recommendation in accordance with the process agreed under clause 3A.1.3.
3A.5.12. Where AEMO requires further information that it considers
necessary to make the recommendation in clause 3A.5.11, the Network Operator, in accordance with the process agreed under clause 3A.1.3, must:
\(a\) provide the further information that is in its possession, power or control; or
\(b\) use reasonable endeavours to obtain that information from the Market Participant responsible for the Transmission Connected Generating System and provide that information to AEMO.
3A.5.13. In making a recommendation whether a Proposed Negotiated
Generator Performance Standard should be approved or rejected in accordance with clause 3A.5.11, AEMO is not limited to considering information provided by the Network Operator and may use any other relevant information available to it.
3A.5.14. AEMO must recommend that the Network Operator reject a Proposed
Negotiated Generator Performance Standard in accordance with clause
3A.5.11 if it reasonably considers that the Proposed Negotiated
Generator Performance Standard may adversely affect Power System Security or Power System Reliability.
3A.5.15. Where AEMO recommends that the Network Operator reject a
Proposed Negotiated Generator Performance Standard in accordance with clause 3A.5.11, AEMO must:
\(a\) provide written reasons to the Network Operator; and
\(b\) in respect of the relevant Technical Requirement, recommend that either:
i. if applicable, an alternative Proposed Negotiated Generator Performance Standard that AEMO considers meets the requirements of clause 3A.5.2(b), which may include a Trigger Event, is adopted; or
ii. otherwise, the Ideal Generator Performance Standard is adopted.
3A.5.16. Subject to clause 3A.5.17, after a Network Operator has
received the recommendation from AEMO under clause 3A.5.11, the Network Operator must determine whether to approve or reject each Proposed Negotiated Generator Performance Standard proposed by the Market Participant responsible for the Transmission Connected Generating System.
3A.5.17. A Network Operator must reject a Proposed Negotiated Generator
Performance Standard in accordance with clause 3A.5.16 where:
\(a\) in the Network Operator’s reasonable opinion:
i. one or more of the requirements in clause 3A.5.2(b); or
ii. in the case of a Relevant Generator Modification, one or more of the requirements in clause 3A.14.1,
are not met;
\(b\) AEMO has recommended in accordance with clause 3A.5.11 that the Network Operator reject the Proposed Negotiated Generator Performance Standard; or
\(c\) in the Network Operator’s reasonable opinion, the Proposed Negotiated Generator Performance Standard will adversely affect:
i. Power System Security;
ii. Power System Reliability;
iii. Power Transfer Capability; or
iv. the quality of supply of electricity for other users of the Network.
3A.5.18. If a Network Operator rejects a Proposed Negotiated Generator
Performance Standard in accordance with clause 3A.5.16, the Network Operator must provide to the Market Participant responsible for the Transmission Connected Generating System:
\(a\) written reasons for the rejection; and
\(b\) if applicable, an alternative Proposed Negotiated Generator Performance Standard that the Network Operator and AEMO consider meets the requirements of clause 3A.5.2(b), which may include a Trigger Event.
3A.5.19. The Market Participant responsible for the Transmission
Connected Generating System may, in relation to an alternative Proposed Negotiated Generator Performance Standard provided by the Network Operator in accordance with clause 3A.5.18(b), either:
\(a\) accept the alternative Proposed Negotiated Generator Performance Standard; or
\(b\) reject the alternative Proposed Negotiated Generator Performance Standard; and
i. propose a different alternative Proposed Negotiated Generator Performance Standard consistent with the requirements of clause
3A.5.2(b), which may include a Trigger Event, in which case the process
for consideration and approval of Proposed Generator Performance Standards in this section 3A.5 applies; or
ii. elect to adopt the Ideal Generator Performance Standard for the relevant Technical Requirement.
3A.5.20. When a Proposed Generator Performance Standard is approved in
accordance with clause 3A.5.4, clause 3A.5.16, or accepted by the Market Participant under clause 3A.5.19(a), it must be recorded by the relevant Network Operator on the Generator Register and it will be a Registered Generator Performance Standard for that Transmission Connected Generating System.
Explanatory Note Section 3A.6 sets out the submission and approval process for Generator Monitoring Plans, including AEMO's obligations and rights in approving or rejecting a Generator Monitoring Plan and the obligations for a Market Participant responsible for a Transmission Connected Generating System to:
in accordance with the Generator Monitoring Plan proposed by the Market Participant and approved by AEMO and included in the Generator Register for the Transmission Connected Generating System. AEMO has an obligation to develop and maintain a WEM Procedure which includes a Template Generator Monitoring Plan and the processes associated with the approval of monitoring plans and reporting of non-compliances. |
|---|
3A.6. Generator Monitoring Plans
Explanatory Note Clause 3A.6.1 is intended to be a civil penalty provision. |
|---|
3A.6.1. A Market Participant responsible for a Transmission Connected
Generating System must:
\(a\) monitor its compliance with the Registered Generator Performance Standards for the Transmission Connected Generating System;
\(b\) once issued an Approval to Generate Notification, have a Generator Monitoring Plan approved by AEMO for the Transmission Connected Generating System at all times; and
\(c\) comply with the Generator Monitoring Plan approved by AEMO for the Transmission Connected Generating System on and from the date specified in the Generator Monitoring Plan approved by AEMO.
Explanatory Note Clause 3A.6.2(a) requires AEMO to specify certain requirements relating to the content of a Generator Monitoring Plan in a WEM Procedure. The requirements are currently referred to as a “Template Generator Monitoring Plan”. However, this name is misleading because the requirements do not constitute a template. AEMO intends to publish a template-like document in Microsoft Word to assist Market Participants in preparing their Generator Monitoring Plans, but does not intend to include that template in the WEM Procedure. Clause 3A.6.2(a) is therefore amended to replace the name “Template Generator Monitoring Plan” with “Generator Monitoring Plan Requirements”. Additionally, clause 3A.6.2(aA) is inserted to require AEMO to include in the WEM Procedure details of the process to be used by Market Participants to submit a proposed Generator Monitoring Plan (which is expected to involve the use of the published template). |
|---|
3A.6.2. AEMO must develop and maintain a WEM Procedure which includes:
\(a\) the following requirements relating to the content of a Generator Monitoring Plan (“Generator Monitoring Plan Requirements”):
i. how a Market Participant responsible for a Transmission Connected Generating System must monitor performance against the applicable Registered Generator Performance Standards including any testing and verification requirements;
ii. the record keeping obligations relating to monitoring compliance with Registered Generator Performance Standards; and
iii. the information and data provision obligations a Market Participant responsible for a Transmission Connected Generating System must comply with when requested by AEMO, the Network Operator or the Economic Regulation Authority, including the form by which that information and data must be provided;
(aA) the process a Market Participant responsible for a Transmission Connected Generating System must follow to submit a proposed Generator Monitoring Plan to AEMO;
\(b\) the assessment and approval process to be followed by AEMO for a proposed Generator Monitoring Plan submitted by a Market Participant responsible for a Transmission Connected Generating System;
\(c\) the process by which a Market Participant responsible for a Transmission Connected Generating System must report any alleged non-compliance or suspected non-compliance with the applicable Registered Generator Performance Standards and the applicable Generator Monitoring Plan approved by AEMO;
\(d\) the process by which a Market Participant responsible for a Transmission Connected Generating System must report that it has not met or complied with, or may not be able to meet or comply with an approved Rectification Plan in accordance with clause 3A.11.9; and
\(e\) the process by which a Market Participant responsible for a Transmission Connected Generating System must submit proposed updates and amendments to a Generator Monitoring Plan approved by AEMO and the assessment process to be followed by AEMO for such updates and amendments.
Explanatory Note Clause 3A.6.3 is updated to reflect the revised Market Information Framework. Rule Participant Network Restricted means information is available to a relevant Network Operator, a Delegate, AEMO, the Coordinator, the Electricity Review Board, the Economic Regulation Authority, other regulators and the specific Rule Participant. Under the Confidential Information classification these parties will still be able to access this information as necessary. |
|---|
3A.6.3. Generator Monitoring Plans and information relating to Generator
Monitoring Plans including outcomes, reporting data and supporting evidence relating to a Generator Monitoring Plan are all Confidential Information.

\(b\) meets the Generator Monitoring Plan Requirements as applicable to the Transmission Connected Generating System, other than in respect of variations that the Market Participant reasonably considers are required on the basis that compliance is not possible, or where doing so would impose unreasonable costs on the Market Participant.
3A.6.5. AEMO must approve a proposed Generator Monitoring Plan if:
\(a\) it meets the Generator Monitoring Plan Requirements as applicable to the Transmission Connected Generating System; or
\(b\) AEMO considers any variations from the Generator Monitoring Plan Requirements as applicable to the Transmission Connected Generating System are:
i. required on the basis that compliance is not possible, or where doing so would impose unreasonable costs on the Market Participant; and
ii. not likely to endanger the safety of any person, damage equipment or breach any applicable law, or pose a threat to Power System Security or Power System Reliability.
3A.6.6. AEMO may reject a proposed Generator Monitoring Plan if AEMO
reasonably considers that:
\(a\) the proposed Generator Monitoring Plan does not meet the requirements of clause 3A.6.5(a);

3A.6.5(a) or clause 3A.6.5(b) as the case may be.
3A.6.9. If the Generator Monitoring Plan Requirements as applicable to a
Transmission Connected Generating System is amended, the Market Participant responsible for the Transmission Connected Generating System must submit an amended proposed Generator Monitoring Plan to AEMO for approval in accordance with clause 3A.6.4 within six months of the amendment to the Generator Monitoring Plan Requirements taking effect.
3A.6.10. A Market Participant responsible for a Transmission Connected
Generating System may submit an amended proposed Generator Monitoring Plan to AEMO for approval at any time in accordance with the WEM Procedure referred to in clause 3A.6.2.
3A.6.11. Where a Market Participant responsible for a Transmission
Connected Generating System submits an amended proposed Generator Monitoring Plan to AEMO for approval in accordance with clause 3A.6.9 or clause 3A.6.10, then clauses 3A.6.5 to 3A.6.8 apply.
3A.6.12. Where AEMO approves a Generator Monitoring Plan, AEMO must
provide:
\(a\) notification of its approval of a Generator Monitoring Plan to the Market Participant responsible for the Transmission Connected Generating System; and
\(b\) each Generator Monitoring Plan approved by AEMO to the relevant Network Operator, and the Network Operator must update the Generator Register to include the most recent Generator Monitoring Plan approved by AEMO.
3A.6.13. Subject to clause 3A.6.14 and clause 3A.6.15, the Economic
Regulation Authority, AEMO or the relevant Network Operator may request that a Market Participant responsible for a Transmission Connected Generating System provide the outcomes, reporting data and supporting evidence in respect of a Generator Monitoring Plan that has been approved by AEMO.
3A.6.14. AEMO may only request the information described in clause

Generating System must provide the outcomes, reporting data and supporting evidence relating to a Generator Monitoring Plan within five Business Days, or longer period if agreed, of a request by the Economic Regulation Authority, AEMO or the Network Operator made in accordance with clause 3A.6.13.
3A.6.17. Nothing in this Chapter 3A prevents AEMO, the Economic
Regulation Authority or the relevant Network Operator from undertaking monitoring activities in respect of compliance with the Registered Generator Performance Standards for a Transmission Connected Generating System.
Explanatory Note Section 3A.7 requires a Network Operator to maintain a register (Generator Register) of approved generator performance standards for each Transmission Connected Generating System connected to its Network. Generator Registers are to be made available to AEMO, Market Participants (as relevant) and the Economic Regulation Authority. Generator Registers will also include the approved Generator Monitoring Plan for each Transmission Connected Generating System connected to the Network Operator's Network. Market Participants are required to provide requested information reasonably required for the purpose of a Network Operator establishing and maintaining the Generator Register and notification requirements of Market Participants to ensure the currency and accuracy of the Generator Register. |
