Consultation on our draft RCP4 proposal

Regulatory Control Period (RCP4) consultation 

Every five years Transpower submits a proposal to our regulator, the Commerce Commission on the total revenue it will recover from customers and the quality of service it will meet for the next five-year period. Our RCP4 consultation document provides an opportunity for our customers and stakeholders to provide their input on how we manage the National Grid.

RCP4 consultation opened on Friday 23 September and closed on Thursday 3 November 2022. 

On Thursday 20 October, we held a webinar where Transpower's Chief Executive Alison Andrew and members of our General Management Team discussed our consultation document. The video is available here.
