NZGP Phase One Shortlist consultation



Transpower consulted on its NZGP1 Stage 1 Shortlist from 30 June to 15 August 2022. The investment options are focused around the the High Voltage Direct Current (HVDC) link between the North and South Islands, the transmission lines in the central North Island, and the lines around the Wairakei area. Following feedback and further development of a preferred option, Transpower developed and submitted a Major Capital Proposal for grid investment to the Commerce Commission in late 2022. 


Thank you to all who submitted on our shortlist. The submissions we received will help us further develop a preferred option and following that an MCP will be submitted in late 2022.
