Some heavy SA users paying 4.5c/kWhr for baseline 24/7 type power so you can bet it costs less than that. And you cannot get power 24/7 from wind/Solar combo. Coal plants profitable at $50/MWhr (=5c kWhr)
Massive investment in storage required to get enough to ride through a wind drought and a few rainy days in a row. Snowy 2.0 and Hydro Tasmania 2.0 still just address the daily peaks and need low cost power pumping at night. The energy stored is still rather minute.
Nuclear has large capital servicing costs but fossil plants exist and fully depreciated in general.
The fuel is in the ground, a gift from God.
Long term it will be all solar, just a question of the time and cost to get there. Why would we meanwhile squander our endowment just so a few publicly-funded Eco-tourists can virtue-signal to their new found friends at the next Paris, or is it Morocco, "or will we see you in Lima?" junket-fest.
