@MattMastodon @Sodis We're going in circles. Volatile sources can only supply 40% of current demand for £50/MWh. The question is what fills the rest.
If storage, then the price goes up immediately by at least two conversion losses from/to storage, in addition to the cost of storage itself. Which doesn't exist at the needed scalability.
Pointing to single projects is not meaningful, as we need to build a fleet anyway, which has its own dynamics.
OK so I have googled the men capacity factor and of course #nuclear has nearly 100% and #renewables only 40%.
But this just means it produces on average 40% of it's capacity. You'd need a sunny windy day to get 100%
What I've read about is a #SWB (Solar wind and battery) system with massive overcapacity
So biomass, hydro and battery can take up the slack when needed. Or gas - which has a very low mean capacity factor <10% but is usually used as a last resort
