This is the fourth regulatory period in which Transpower has an individual price-quality path in place.

Transpower’s price-quality path will be reset in 2024 for the next regulatory period commencing 1 April 2025.

We began our stakeholder consultation on 9 October 2023 with the publication of our Transpower RCP4 Process, framework and approach paper, followed by publication in January 2024 of our RCP4 Issues paper.

On 29 May 2024, we published our RCP4 Draft decision. Commissioner Vhari McWha also hosted a presentation to stakeholders and media, which can be found below.

On 29 August 2024 we published our RCP4 Final Decision on expenditure allowances, quality standards, compliance obligations, IPP-specific information disclosure requirements, and the revenue path design.

On 20 November we published our RCP4 Final Determination and Companion paper.
