Wholesale Market Information Disclosure

The Authority and Transpower held a joint briefing on information disclosure on Wednesday 3 March 2021.

In January the Authority announced a decision to amend the Electricity Industry Participation Code 2010 (Code) to improve the availability of thermal fuel information. The Code amendment which comes into force on 1 April 2021 imposes obligations on a new class of participants, called major participants, including an obligation to report to the Authority on how they are meeting their disclosure obligations under clause 13.2A of the Code.  

The Authority provided an overview of these new rules. To check if your company comes under the definition of ‘major participant’ see here.

Transpower and the Gas Industry Company also provided updates on their disclosure workstreams.

The briefing covered:

• summary of new information disclosure reporting obligations
• update from Transpower on new guidance for participants on what outages might impact the system operator’s ability to meet its Principal Performance Obligations
• update from Gas Industry Company.

Slides from the briefing can be found below.

We have published our Wholesale market information disclosure: review of thermal fuel disclosure consultation paper.

We anticipate that the proposals in the paper will increase visibility of market activities and allow participants to better manage risk, which will benefit consumers in the long-term through more efficient prices.

We held a briefing on Friday, 14 August 2020 to support stakeholders understanding of the paper.

The briefing covered:

• key points from the consultation paper
• an explanation of key data sources in understanding the interaction of the gas and electricity markets
• an update from Gas Industry Co.

The presentation slides are available below.

On Tuesday, 8 August 2017, we published our Wholesale market information: Review of disclosure regime consultation paper. The consultation paper includes an updated version of the Guidelines for participants on wholesale market information disclosure obligations (guidelines). Submissions close on 3 October 2017.

We held a workshop in Wellington on 12 September 2017.

The objective of the workshop was to clarify and further explain the proposed amendments to the Electricity Industry Participation Code 2010 (Code) designed to enhance the disclosure of wholesale market information, and the associated updated guidelines.
