they all conveniently skip or gloss over the base load or constant source - this is the problem that needs to be solved first and now.
Spot on!!!!!!!!!!!!!!
The requirement for storage is conveniently forgotten by the commentators.
So what period of supply does a storage system attached to PV/Wind need to cover.
The period of supply for a coal/gas power station is the life of the station or coal/gas source.
The period of supply for storage attached to a PV/Wind source is? minutes - hours - days. Certainly not weeks or months.
I know from personal experience, that PV can have periods where the output can be less that 10% for a period of days. Get a week of rain and you would be stuffed.
So what would be the cost to build a storage system to store the equivalent power output of Liddell for at least 7 days?
How big would the PV/Wind supply need to be to supply enough power for the normal consumption while recharging the storage system within a reasonable time.
