Renewables growth energises spending as inflation rises

The latest figures from the Australian Bureau of Statistics (ABS) on Private New Capital Expenditure have highlighted a significant divergence in the national economy. While traditional sectors like construction and manufacturing are showing signs of cooling—with construction work done falling 0.1% in the final quarter of 2025—the energy sector is experiencing a robust influx of capital. This surge is primarily fueled by the rapid expansion of renewable energy infrastructure, including large-scale solar farms, wind projects, and battery storage systems. The data suggests that the transition to a low-carbon economy is no longer just an environmental imperative but a primary driver of domestic investment.

The timing of this investment boom is particularly noteworthy as Australia grapples with persistent inflationary pressures. With headline inflation holding steady at 3.8% and the Wage Price Index climbing 0.8% in the most recent quarter, the cost of developing large-scale energy projects has risen substantially. Higher interest rates, intended to curb inflation, have increased the cost of capital for developers. However, the ABS data indicates that these headwinds have not yet dampened the appetite for renewable energy assets. Instead, the strategic necessity of replacing aging coal-fired power stations and meeting state and federal emission targets is overriding short-term fiscal caution.

With headline inflation holding steady at 3.8% and the Wage Price Index climbing 0.8% in the most recent quarter, the cost of developing large-scale energy projects has risen substantially.

A major catalyst for this sustained spending is the Australian Government’s aggressive policy framework, specifically the 82% renewable energy target by 2030. The expansion of the Capacity Investment Scheme (CIS) has provided a level of revenue certainty that is attracting both domestic and international institutional investors. By underwriting new renewable and storage capacity, the government has effectively de-risked these projects, allowing them to proceed despite the inflationary environment. This policy support is crucial as the industry faces supply chain bottlenecks and a tightening labor market, which have contributed to the rising cost of components like wind turbines and specialized electrical equipment.
