Regulatory Control Periods

Every five years Transpower must submit a proposal to our regulator, the Commerce Commission, on how we will operate, maintain, and invest in the grid. The Commission sets the allowance and measures of service quality that Transpower is incentivised to deliver on for the following five-year period (known as a Regulatory Control Period or RCP). 

We are currently in RCP3 which covers 2020 to 2025. We are also in the process of preparing our proposal for RCP4 for the Commerce Commission and will be engaging with our customers and interested stakeholders as we develop the proposal.

You can find more information on each period by selecting from the below:
