Overview
This article presents experimental estimates for the level of renewable investment in the electricity generation, transmission and distribution sector from the March quarter 2016 to the June quarter 2024.
The level of investment in renewable generation and storage technology has increased significantly since 2016-17. Commencements for renewable projects reached their highest level in 2022-23 while the value of work done on renewable projects reached its highest level in the 2023-24 financial year. Both renewable and other electricity investment recorded their highest quarterly levels of work done in the June 2024 quarter. The increase in other electricity investment in June 2024 highlights the increased investment in transmission and infrastructure following the sustained investment in renewable generation assets.
Investment in renewable generation has been impacted by various factors over the period highlighted. These include a changing regulatory environment, access to finance, grid capacity constraints and the COVID pandemic. The impact of these factors is not discussed explicitly in the analysis presented in the article however should be kept in mind when interpreting the findings.
Source
Investment data has been sourced from the Engineering Construction Survey, which is published in Construction Work Done, Australia, Preliminary, and Engineering Construction Activity, Australia quarterly publications. Data is collected under the type of work 'Electricity Generation, Transmission, and Distribution', and has been broken down by type of investment for the purpose of this article. The data presented will not be available on an ongoing quarterly basis.
This is not a comprehensive account of economy wide investment in renewable energy and the following considerations should be taken into account:
- Rooftop photovoltaic systems are out of scope for the Engineering Construction Survey.
- Given electricity investment includes transmission and distribution data as well as generation, the information presented should not be read as an analysis of new generation projects only.
- While the renewable data is primarily generation and storage investment, data pertaining to other assets includes non-generation investment such as maintaining and expanding existing transmission networks.
More detail on the scope of the data presented can be found under the 'Method' section below, or by accessing the Engineering Construction Activity methodology page.
