Capacity factor is calculated into lcoe, what's your point? Moreover, downtime for wind turbines is much less of an issue for a grid than large power plants (even with a significantly higher capacity factor), because you run into much bigger issues if your GW plant is down, compared to a couple of MW (and no the probabilities of all your renewables mix going down at the same time is very low, unless you're Luxemburg)…
Capacity factor is calculated in. But intermittency is not. The issue is that once demand is saturated during periods of peak production, the excess energy is wasted so the effective capacity factor drops as adoption grows. E.g. once you saturate daytime energy demand, further investment in solar energy yields no more useable energy. Intermittent sources are a good way to supplement dispatchable sources of energy lik…
E.g. today in Germany you can buy MWh at 14€ at 13:00 and sell it back at 180€ at 18:00. I didn't look all of Europe but it looked like the biggest spread today... You can make money with crappy storage under those conditions...
