That is false.
What you have is subsidisation for renewables both financial and regulatory where coal is penalised.
Remove the subsidisation as well as opportunistic bidding and see what happens. If one bids to supply power it has to be done at a min of 24hr blocks not this nonsensical 5 to 10 min units
Regardless, wind and solar cannot supply the required power as it is intermittent and does not operate 24/7/365, moreover huge costs are still to be incurred in building out transmission infrastructure
Wind and solar simply does not have the power leverage and density that nuclear, coal or gas have.
Everywhere renewables % increases 2 things happen 1) power prices rise and 2) unreliability increases
Finally wind and solar are detrimental to environment requiring huge clearing of vegetation. It is environmental vandalism
No country has made it work and Australia is engaged in a folly which will have to be corrected in years to come
