      Yep. The latest CSIRO/AEMO report published this week addresses exactly this, with various levels of renewables penetration modelled, including associated firming costs (additional transmission & storage) Here’s an overview (spoiler: renewables are still cheaper by far.) https://www.abc.net.au/news/2023-12-21/nuclear-energy-most-expensive-csiro-gencost-report-draft/103253678?utm_source=abc_news_app&utm_medium=content_shared&utm_campaign=abc_news_app&utm_content=link

        If u go look at the spurce document and not a report on the document i found a couple interesting things.

        1. Risk profiles have not been considered due to renewables variation etc
        2. The nuclear costs are all based on one reactor from a single startup and overlooked the multitude of other reactors around the world at significantly better prices
        3. Renewables where assumed to go down in cost but we have seen that the cost of storage has actualy been rising recently
        4. Why does the IEA think nuclear is still cheaper?

          Are you able to link the source document?

          However, as an example of why nuclear is seen as risky, time-consuming and subject to massive cost blowout and time delays, see Flamanville 3 ( https://www.world-nuclear.org/information-library/country-profiles/countries-a-f/france.aspx Under “new nuclear capacity”)

          It’s gone from being a project started in 2004 to build a 1650MWe plant costing 4.2 billion euros (in 2020 euros), to an estimated completion date of 2024, at 13.2 billion euros.

          And this is France, a country that is very familiar and well-versed with building nuclear reactors.

          Without the source document, this may well be the example you use from your 2nd bullet point. But I wouldn’t have called this a startup.

              THEY FUCKING MISSED AN ENTIRE CLASS OF NUCLEAR REACTOR. They had one fucking job compare all the power options and they ignored any reactor that was not a small scallable bullshit silicon valley hyptrain piece of shit. This “unbiassed” report funded with million of dollars just happened to accidentally forget the cheapest and most economically efficient reactor design this is heigly sus and very much looks like it is purposefully misleading. I thought the CSIRO was unbiassed but this is an aggressiouse error that canot be overlooked.

        Does this not only look at 2023 to 2024 would that not skew it towards options that have a low upfront cost? Nuclear is strongest in the longterm not over the period of 1 year.
