Rule Change: Open

Overview

This rule change request from the Australian Energy Council seeks to enhance publicly available information about new grid-scale projects. It has been consolidated with rule change requests from the Australian Energy Market Operator (AEMO) and Energy Networks Australia. The consolidated rule change request also seeks to allow developers of new projects to register with AEMO to get access to key technical information such as network modelling data.

This rule change request from the Australian Energy Council seeks to enhance publicly available information about new grid-scale projects. It has been consolidated with rule change requests from the Australian Energy Market Operator (AEMO) and Energy Networks Australia. The consolidated rule change request also seeks to allow developers of new projects to register with AEMO to get access to key technical information such as network modelling data.

Consolidation of related rule changes

The Commission has consolidated this request with two other rule change requests that also seek to promote the transparency of new generation projects and improve information provision in the national electricity market:

  • NEM information for project developers (ERC0260) submitted by Australian Energy Market Operator (AEMO)
  • TNSP exemptions from confidentiality requirements (ERC0268) submitted by Energy Networks Australia.

These rule change requests have been submitted in response to the significant increase in generation connections and the emergence of new business models for generation projects. 

The AEMC published a consultation paper covering the three proposals on 18 April 2019.

Draft determination

On 1 August 2019 the Commission published a draft determination that improves information provision for new projects in the NEM. 

The Commission’s draft rule:

  • facilitates greater access to relevant system information for developers that sell grid-scale assets prior to connection, while recognising that certain types of developers can already access this information by registering as intending participants. The draft rule will also make more information about new projects more readily available.
  • codifies AEMO’s generation information page in the NER, which is an information resource that will provide a source of regularly updated data on existing and proposed connections to the national grid. 
  • requires TNSPs to share basic connection information about new projects with AEMO. AEMO must then publish this data on the generator information page. 

The draft rule supports the energy market transition by making it easier and quicker for developers to assess the viability of proposed projects. The draft rule also means market participants are better informed of proposed connections which may assist them with their operational and investment decision-making.

Stakeholder submissions on the draft determination are due by 12 September 2019.

Background – rule change requests

On 15 December 2018 the Australian Energy Council submitted a rule change request to the Commission seeking to increase the transparency of new projects. The request has four key parts: 

  1. Codifying AEMO’s generation information page in the National Electricity Rules (NER). 
  2. Imposing a requirement on intending participants to provide updated information to AEMO, for example when their projects change. 
  3. Reforming the intending participant category, consistent with the proposals made by AEMO (discussed below). 
  4. Enabling AEMO to disclose confidential information if it reaches the public domain. 

On 31 December 2018 AEMO submitted a rule change request seeking to allow a developer to register as an intending participant for the purposes of building a grid-scale generating system or an industrial development (e.g. a load), despite such a person never intending to register as market participant.

On 15 March 2019 Energy Networks Australia submitted a rule change request seeking to explicitly allow transmission network service providers (TNSPs) to publish certain information they have received from connection applicants regarding new and proposed generation connections.
