4-9's of uptime doesn't match my lived experience in the US, that's one days worth of power outage every 10000 days, or about once every ~30 years. 2-9's is closer to what civilians in the US are used.
The over provisioning could be considered more of a feature than a bug, offering new economic periods where the marginal energy cost of production go negative at times.
- mlyle 3y ago> 2-9's is closer to what civilians in the US are used. ??? Like 4 days of downtime per year? I've had about 1.5 hours of outage this year, which was an outlier (much more outage than normal). 3 9's is typical if you have above-ground utilities. If you have underground utilities, you may be doing far better than this...
- wolfram74 3y ago8 hours a year is pretty close to 3-9's, that's fair.
- zizee 3y agoThat's fine. 4-9's was just an number I pulled out of my ass, and it wasn't really my point. My point is that when talking about energy sources, LCOE is not a good measure as it doesn't take into account things like reliability over time (whatever your target reliability is). Over-provisioning has a cost. If it is required to achieve characteristics required to do a like-for-like comparison, it should be accounted for. The problem with these Nuclear conversations is that people are pushing their preferred option, always without coming to some sort of agreement on what the requirements are for the power generation option. Without agreeing on what needs to be achieved, everyone talks past each other, arguing with straw-man solutions.
