I found a more updated new Gov coalition agreement and your right they are likely going to fire up the reserve coal plants during times of high electric prices rather than just supply gaps like it's been doing. Proves coal power is cheaper than renewables i suppose.
" In a move likely to prompt further debate, reserve power plants will be permitted to return to the market temporarily during periods of price volatility to help moderate prices – a shift from their traditional role of covering supply gaps."
They have also committed to advancing fusion research with an aim of building the first commercial fusion reactor which is something different.
