Our proposed five-year workplan

Our regulatory control period four (RCP4) proposal for 2025-2030.

We submitted our regulatory control period 4 (RCP4) proposal, covering the period 2025 to 2030, to the Commerce Commission on 21 November 2023.

During RCP4, we are seeking to deliver on the following outcomes.

Image	A reliable and safe network We will deliver a transmission service that minimises interruptions at lowest whole of life cost, where assets are maintained and replaced in line with good electricity industry practice, and where risks to our staff, contractors and general public are minimised.
Image	A resilient network A resilient network avoids extended power outages and quickly restores power when major events occur.
Image	Enhancing the network We aim to ensure capacity is in the right place at the right time and customers continue to receive a reliable and secure transmission service that meets their needs.
Image	A sustainable network We will reduce our carbon footprint over RCP4 to ensure we can achieve a 60% reduction in emissions by 2030 in our aim to reach a net zero target by 2050.
