As you say "let's compare them on the same basis". The Renewable Energy Target (RET) means that AEMO must take electricity from renewable energy and leave the scraps to base load who cannot take their generation below limited thresholds, takes start up time and knocks the hell out of the machinery by being ramped up and down to cater for the scraps as "tail end charlie". The the Victorian government asserts that it will not pay for capacity and standby meaning that baseload generators do not get paid for idle or low load conditions - no wonder they want to throw in the towel as they have done in the UK. Furthermore "inertia" is required for grid frequency/load stability - renewables (apart from pumped hydro - not usually generation largely storage) is essential - without the kinetic energy in the rotating machinery (not inverters for windmills/solar) grid stability will go haywire. I wish we had engineers making decisions rather than ecologists, sustainability, environmentalists and worst of all politicians like Chris Bowen who make highly misleading and incorrect utterances like "it's just a joke - they propose the most expensive; nuclear ". It's all a bit like going out an buying a cheap car which will only work on some days between 9am and 3pm and always goes on strike at night or when the wind decides to blow. To me renewables (without other ***bins) you have to compare on a like for like and add to the cost all the system components needed to supplement them (i.e batteries - with 10 years life, grid extensions to remote locations, land, synchronous condensers (for inertia), pumped hydro (like Snowy 2 now over budget at $5,1Bn and maybe 2026 and 80% round trip efficiency) and back up turbines (fired highly inefficiently with green hydrogen or ammonia fuel belching noxious nitrous oxides) that are needed about 4 times a year for 3 consecutive days when the wind decides not to blow and there is little sunshine (i.e in the winter).2 - I just hopes he also holds his breath indefinitely (that produces CO2 and farts into a bag eliminating fugitive methane emissions).

Pathetic insults are unbecoming of polite debate. I only shared AEMO's impending decision on Australia's future energy plans (ISP) because I thought it was pertinent in relation to nuclear generation and of interest to investors.
