Welcome to Market Brief, the Electricity Authority’s weekly update on regulatory and market developments.


Switch Process Review

Late last year we consulted on a number of issues that were hindering the smooth operation of Installation Control Point (ICP) switching processes. After analysing submissions, we are:
  • publishing a summary of submissions 
  • carrying out a further consultation. 
The paper “Switch Process Review - Issues with the ICP switching processes and possible options to address these issues” sets out the issues and proposes amendments to the Electricity Industry Participation Code 2010 (Code) to address the issues. Submissions close on 17 December 2019.

We are holding a workshop in Wellington on 20 November to ‘walk through’ the proposals. More information on the workshop is available on our website.

Reminder: Call for nominations for Standing Data Formats Group

We are calling for nominations for a metering equipment provider (MEP) member to join the Standing Data Formats Group (SDFG). The SDFG provides independent advice to the Authority on information exchange protocols between participants and:

  • the market operation service providers
  • consumers
  • third party providers.

The group is currently advising on the method of transfering notifications for EIEP5A planned outages and a proposal to mandate one reporting methodology for distributor billing for EIEP1. There are several new projects in the pipeline including considering creating new standardised formats for smart metering data and considering options for a standard format for MEPs to provide data to traders.

We will appoint the successful nominee in November 2019 for an expected term of three years.

Please use our online form to submit nominations and accompanying documents. Nominations close at 5pm on Tuesday, 29 October 2019.

Reminder: Compliance investigation for participants to join – deadline 24 October

The Authority has commenced an investigation into an alleged breach of the Code by Transpower New Zealand Limited as the grid owner.

The grid owner self-reported that it had breached clause 4(4)(a)(ii) of Technical Code A of Schedule 8.3 of the Code. On 19 November 2018, the grid owner’s protection system at its Wairakei substation was not selective when operating, causing a disconnection of generation and loss of supply to Taupo. 

Participants who consider they are affected by the matter being investigated may join as a party to the investigation. To join the investigation, participants should notify the investigator no later than Thursday, 24 October 2019. The investigator’s contact details are in the notice of investigation on our website.
