Improving visibility of generation investment

We have created an investment pipeline dashboard that summarises the data on current generation and the expected new generation from the Authority-commissioned 2022 and 2023 investment surveys. There is also a list of investment projects which have been publicly announced, with information on each project’s status as used in the surveys.

We will publish a consultation paper in mid-2024 that seeks industry feedback on the level of generation investment information we will collect and what we will publish.

There is currently limited information available about generation projects in the pipeline. The aim of this project is to collect and publish data on the pipeline of investments in new generation (and load) connecting to the transmission network and distribution network (above a certain capacity).

Improving the visibility of generation investment will help with monitoring long-term security of supply. It will will also support the monitoring of competitive outcomes and constraints to investment, as well as support investment confidence and provide information for investment decisions.

This work aligns with recommendation 17 in tranche 2 of the Market Development Advisory Group’s report Price discovery in a renewables-based electricity system. It also builds on the 2022 and 2023 Generation Investment Survey and Transpower’s existing connection enquiry dashboard.
