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.
- Risk profiles have not been considered due to renewables variation etc
- 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
- Renewables where assumed to go down in cost but we have seen that the cost of storage has actualy been rising recently
- 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.
