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


Decision published: Integrating hosting capability into Part 6 of the Code

In September 2018, the Authority consulted on the issues that may be caused by the connection of small-scale distributed generation (SSDG), storage batteries, and electric vehicle in-home chargers to distributors' low voltage networks. Collectively, these technologies are referred to as distributed energy resources (DER).

We have released a decision paper setting out the results of the submissions received and the next steps. An associated summary of submissions will be published shortly.

We have concluded an amendment to Part 6 is required to address the issue and further consultation on proposed Code amendments will follow.

2018 electricity consumers’ survey released

The Authority regularly surveys electricity consumers as part of its monitoring of the retail market. These surveys ask questions about consumer experiences in the retail electricity market. The sample is split into respondents that switch, respondents that think about switching but don’t switch, and the remainder that do not contemplate switching. 

The 2018 survey is now available on our website.

Beginner registry user training – expressions of interest sought

The Authority is considering running a training course for registry users in Wellington on 25 and 26 September 2019 and Auckland on 23 and 24 October 2019.

The course is suitable for new registry users and participants wanting to gain knowledge of how the registry and associated processes work. Attendees will engage in hands-on exercises and will receive practical experience in:
  • the operation of the registry
  • the lifecycle of an ICP, including the registry roles of distributor, trader, and metering equipment provider.
We need to set up individual workstations for registry access, so total attendance numbers are limited. Numbers may also be limited by organisation and relevance of the training to the individual.

If you are interested in attending the course, please email your name, contact details, and preferred location to by COB Tuesday, 20 August 2019 with ‘registry training’ in the subject line. Please do not book flights and accommodation until you have received confirmation of attendance.

Amendments to EIEPs come into force 1 October 2019

On 1 October 2019, amendments to Electricity Information Exchange Protocols (EIEPs) 1-4, 5B, 6-9, 11, and 12 will come into force. We have made these amendments to:
  • add clarity and consistency to the EIEP formats and business requirements
  • correct content where appropriate
  • enhance usefulness by making some changes to functionality and business requirements.
If you are a trader or distributor, you should discuss these amendments with your technical staff and IT providers. We also encourage you to start modifying your systems to use the amended EIEPs. 

We have set up a webpage with implementation memos and questions asked by participants about the amended EIEPs. The first memo contains up-to-date implementation details and links to the amended EIEPs. You can send any EIEP implementation questions to

Spotlight on emerging contestable services project update

The Spotlight on emerging contestable services project – a joint initiative of the Authority and Commerce Commission – is pausing while the Commission focusses on projects with statutory deadlines, including the price-quality path resets for electricity distributors and Transpower. 

The Authority and Commission believe the spotlight project is important, and we appreciate the interest and engagement stakeholders have provided to date. We expect to restart work once the price-quality path resets are complete.

Participant update required: contact lists in the registry

We request that participants review, and if necessary update, the contact lists in the registry. The lists enable the Authority, registry, and participants to help identify the correct contacts within each organisation. The contact lists are split into two different types:
  • a participant contact register: where registry users can view each other’s email addresses. The participant contact register is used by participants and the Authority 
  • email groups: with email addresses only visible to the responsible participant. Email groups are only used by the registry manager and the Authority. 
Participants can update and maintain their contact lists using their organisation supervisor logon. Detailed instructions are in the registry user manual (chapters 16 and 17).
