Germans in their Kombikraftwerk study back in 2007, figured out that you need 5x the capacity (compared to the average usage) to cover entire annual (and daily) fluctuations of the grid with renewables, without storage (more exactly, with that little storage they already have - in the form of a few pumped hydro plants). I tend to still trust this study, there are no counter-arguments to speak of.
- tsotha 13y agoI believe that, assuming the study includes wind and biomass. But 5x capacity is going to be expensive to maintain.
- anovikov 13y agoYes, it included biomass and more importantly, biogas, which acted as flexible means of generation. That 5x capacity in fact, did not result in significant losses of power, it was in the range of a few percent as i remember.
