Amendments to Transpower information disclosure requirements 2024

The purpose of Part 4 of the Commerce Act 1986 is to promote the long-term benefits for consumers in markets where there is little or no competition and little or no likelihood of a substantial increase in competition.

Part 4 requires Transpower to disclose information about their performance with the aim of encouraging them to improve efficiency and quality as well as incentives to innovate and invest.

The legal framework we apply when setting or amending ID requirements to Transpower is set out in the Part 4 Information Disclosure Framework paper.

We have now published our submissions on our Draft Decision. We received no cross submissions. We intend to publish a final decision in Q4 2024.

The need for this review

The purpose of the ID (Transpower Amendment Determination 2024) review is to align ID requirements with the changes arising from the Input Methodologies Review 2023 and the new Transmission Pricing Methodology (published by the Electricity Authority).

We have  also considered some  changes from Transpower exemptions to information disclosure requirements and fixing simple clarifications and errors. The focus is on amendments which need to be implemented by April 2025.

Throughout this process, we will be working closely with Transpower and other stakeholders on changes to ID requirements which we expect to improve the long-term benefit of consumers.
