A recent study found that nuclear power needs to come down 85% in cost to be competitive with renewables when looking into total system costs for a fully decarbonized grid, due to both options requiring flexibility to meet the grid load.
> The study finds that investments in flexibility in the electricity supply are needed in both systems due to the constant production pattern of nuclear and the variability of renewable energy sources. However, the scenario with high nuclear implementation is 1.2 billion EUR more expensive annually compared to a scenario only based on renewables, with all systems completely balancing supply and demand across all energy sectors in every hour. For nuclear power to be cost competitive with renewables an investment cost of 1.55 MEUR/MW must be achieved, which is substantially below any cost projection for nuclear power.

> Exactly, paying an obscene amount of money now means that in 90 years' time, that money is much cheaper compared if you had to spend it in 90 years, or every 20 years to replace your renewables and storage parks.
Great that you admit to having zero economic knowledge. That is the exact reverse of how it works.
Money now are worth way more than money in the future, even when adjusting for inflation etc.
Thus the need for short cycles and the huge risk premiums that get added when going above 10-20 years.
Here’s some reading for you:

- sofixa 2y ago> Great that you admit to having zero economic knowledge. That is the exact reverse of how it works. Not when we're talking about infrastructure at the state level. Project costs of big infrastructure projects, as well as inflation, mean that getting stuff done now is better and cheaper, usually, than waiting to do it in a few decades, or redoing it every few decades. State-level infrastructure investment doesn't have the same earnings potential as regular investment. It's practically all very long term, kind of by definition (if it were short term profitable, private investors would be all over it).
- ViewTrick1002 2y agoWhat's the problem with redoing it every few decades when you can deploy new more efficient technology, make profit on your investment and it is cheaper for the consumers? You do know that the full cost including investment for renewables with a 10-20 year ROI are about equal to what running paid off nuclear plant costs? Excluding the accident insurance [1] and decommissioning costs for nuclear power. A 90 year nuclear project compared to investing every 20 years in more efficient renewables mean: Assume a 20% ROI, which is very low but easy to calculate. Year 0: 100% in renewables Year 20: You have 120% to reinvest. You can now build 120% of renewables plus whatever efficiency gains we had in the last 20 years. Year 40: you have you have 144% of the original investment to deploy + 40 years of efficiency gains. Year 60: you have 173% of the original investment to deploy + 60 years of efficiency gains. Year 80: you have 207% of the original investment to deploy + 60 years of efficiency gains This is why building nuclear power with a 90 year pay off time is pure idiocy. Building renewables with a short pay off time led to us to have double the energy in 80 years time while also being able to deploy 80 years more modern technology. Maybe you should look up how compound interest works? [2] Why you do you keep suggesting the scenario where we simply lose money? Because you entwined your identity with a power source and are using you lack of understanding of economics to try justify it? Private investors are all over renewables?

- sofixa 2y ago> Assume a 20% ROI, which is very low but easy to calculate. 20% net ROI sounds a bit high for renewables from 20 years ago, do you have any source? > You do know that the full cost including investment for renewables with a 10-20 year ROI are about equal to what running paid off nuclear plant costs Source? Cost of electricity in France being lower than Germany seems to imply otherwise. And that's ignoring the need for storage in a fully renewable grid. > Private investors are all over renewables? Exactly, private investors are all over short-term profitable ventures. They won't be all over something which requires multiple decades to become profitable.
