CSIRO’s GenCost report reaffirms wind and solar as Australia’s most cost-effective electricity generation
Renewables, led by wind and solar, have retained their position as Australia’s cheapest new-build electricity generation despite a 20 per cent average rise in technology costs, according to the latest GenCost report. The 2022-23 report marks the first time that all technology costs have increased from the previous year since GenCost commenced in 2018. The report highlights industry concerns that the rapid pace of the global energy transition will contribute to escalating cost pressures. This is attributed to the immense scale of manufacturing, raw materials and labour required to develop and deploy clean energy technologies consistent with net zero goals. GenCost modelling projects that technology cost pressures felt in Australia will revert to normal levels by 2027 but are delayed to 2030 in global scenarios where the speed of the energy transition is highest. GenCost is an annual collaboration between CSIRO and the Australian Energy Market Operator (AEMO) that actively consults industry stakeholders to revise domestic electricity generation and storage, as well as hydrogen production costs. CSIRO’s Director of Energy, Dr Dietmar Tourbier, said GenCost’s rigorous scientific and engineering analysis represents Australia’s most comprehensive projection of electricity generation costs. “Australia’s energy challenge lies in the transformation of our existing energy system, while ensuring the continuing delivery of sustainable, reliable and affordable energy as we strive to achieve net-zero emissions by 2050,” Dr Tourbier said. “This imperative is not only essential for environmental stewardship, but also to maintain Australia’s economic competitiveness in the global market,” Dr Tourbier said. CSIRO’s Chief Energy Economist and GenCost lead author, Paul Graham, said that the COVID-19 pandemic had resulted in lingering global supply chain constraints which impacted the prices of raw materials required in technology manufacturing as well as freight costs. The Ukraine war exacerbated the global supply chain inflationary pressures by raising energy input […]
