Retailers must now provide:

  • consumers, or a consumer’s authorised agent (agent), with their electricity consumption data
  • generally available retail tariff plans to any person upon request.

The Authority has also made consumers’ connection data, held in the registry, publicly available. Having access to connection data will enable consumers or their agents to identify retailers’ tariff plans that are applicable to a given connection.

Access to consumption information

This is a consumer focused initiative intended to promote retail competition by making it easier for consumers to use their consumption data to make more informed decisions about their retailer and retail tariff options. The amendment is part of a programme of work called the Retail Data Project. 

In order to implement this Code amendment the Authority has;

  • developed three electricity information exchange protocol (EIEP) formats (13A, 13B, 13C) to enable the data to be exchanged in a standardised format. 
  • developed a procedures document to support the standardised exchange of data, 
  • opened up the use of the EIEP transfer hub to agents 

The EIEP formats and the procedures document are regulated under the Code and came into effect on 1 February 2016. 

The EIEP documents can be found on the EIEP page.

The procedures document can be found below 

A list of current non participant identifiers can be located on sheet 2 of the participant identifiers list.

Access to tariff information

Clause 11.32G of the Code requires retailers to make available their current generally available retail tariffs to any requesting person within 5 business days.

If the person requests the information in a format other than what the retailer would normally provide, the retailer can impose a reasonable charge.

In order to support the standardised exchange of data, the Authority has developed electricity information exchange protocol (EIEP14), a voluntary format that retailers can use when providing tariff information. The voluntary format is available on the EIEP webpage

As part of the implementation of this initiative we published a list of frequently asked questions, implementation memos and the EIEP test files
