Fact sheets: Comparative energy costs and fossil generation failure in the 2017 heatwaves
NEM Fossil generation failure in the 2017 heatwaves
During the February 2017 heatwave across south eastern Australia, 14% of fossil generating capacity (3,600 MW) failed during critical peak demand periods in South Australia, New South Wales and Queensland as a result of faults, largely related to the heat.
Comparative energy technology costs
- Electricity from new wind and solar plants is now cheaper than from existing gas plants.
- Electricity from wind is cheaper than coal or gas, even with additional “firming” costs that ensure its availability 24/7.
- Solar thermal is cheaper than gas peaking plants for flexible dispatchable generation.
