Hmm… one of the key arguments made by the LNP and their supporters is the need for coal (and, to a lesser extent, gas) power stations to provide reliability. Even their nod at a renewables option – the Snowy 2.0 project – is about providing reliable baseline power.
So what does the Australian Energy Market Operator say? “Extreme weather over summer could reduce the output of COAL, GAS and HYDRO power generators and cause problems with the reliability of electricity supply”
