5 reasons why wind farms are costing more in Australia – and what to do about it
Building a solar farm in Australia is getting about 8% cheaper each year as panel prices fall and technology improves, according to an official new report. Battery storage costs are falling even more sharply, dropping 20% over the past year alone.
But the same can’t be said for wind farms, the second-largest source of renewable energy in Australia. Onshore wind costs actually rose about 8% in 2023–24 and another 6% in 2024–25.
The findings are contained in the GenCost 2024–25 report by CSIRO and the Australian Energy Market Operator, released this week.
