that claims “renewables and batteries can do it all” were false. And he’s right, of course – but no serious electricity system expert is making that claim.“You need this thing called firming. And the firming can only come through coal fired power stations or gas,” said Littleproud, adding the now obligatory rejoinder for the Coalition that “small-scale modular nuclear” could also work to stabilise the electricity network.
Coal generation disappears completely by the year 2043. By 2050, AEMO expects more efficient and responsive gas plants are available to provide 10GW of electricity. According to Aemo’s plan, by 2050 there will be a trebling of “the firming capacity from alternative sources to coal that can respond to a dispatch signal, including utility-scale batteries, hydro storage, gas-fired generation, and smart behind-the-meter ‘virtual power plants’”‘.
'But this is dwarfed by 61GW of available electricity stored in batteries...' Batteries don't store 'GW' which is power, they store energy, which could be GWh. Huge distinction.
Making energy expensive ensures people don’t care for the environment. Sure renewables produce cheap electricity, but it’s really expensive to get them to produce when the sun has gone to bed or the wind is having a rest.
