This amendment to the Electricity Industry Participation Code 2010 ("Code") comes into force on 30 November 2021.

This amendment inserts new clauses 13.256 to 13.266 into Part 13 and new definitions into Part 1 of the Code. The purpose of the amendment is to increase trust and confidence in the wholesale and retail markets by:

(a) increasing transparency on how large vertically integrated generator-retailers price electricity for their own retail arms; and

(b) increasing transparency on retail revenues and gross margins amongst retailers who were recorded in the registry in any of the preceding 12 months as being responsible for 1% or more of the total number of ICPs with a status of "Active".

The new clauses:

(a) impose reporting obligations on large generator retailers to disclose annually information relating to their internal transfer pricing and supporting information, and to disclose further information in particular circumstances if the generator retailer changes the methodology used to determine internal transfer pricing during a year;

(b) impose reporting obligations on retailers who were recorded in the registry in any of the preceding 12 months as being responsible for 1% or more of the total number of ICPs with a status of "Active" to submit annual retail gross margin reports relating to the sale of electricity to mass market customers by the retailer;

(c) permit the Authority to publish the information it receives as a result of the new reporting obligations; and

(d) provide the Authority with the power to require a review by an independent person of whether a generator retailer or a retailer subject to the new reporting obligations has complied with those obligations.
