if you looked at the data link, you would have been able to see they already had many of their gas peaker plants running, but they were not prepared for the near total drop in wind and the exceptional sudden demand peak.Punx0r wrote:With a little practice and some past data, it is not beyond the wit of man to reliably predict the sunshine/wind/waves a few hours in advance. Bringing gas peaker plants online occasionally might be inefficient utilisation of them, but it's practical and achievable.
Remember up to this point rhey were already generating 5-10 GW surplus to demand.
i suggest you stick to predicting future weather patterns etc, ..because your mind reading skill fall short on accuracy !.Punx0r wrote:....Your position seems to be "if 100% RE can't be implemented immediately, with complete reliability, no change in required usage patterns and no increase in cost then why bother with RE at all?" ...
You obviously have no clue of "my position" , or my interest in RE power implementation .
Aaahh, now your prediction skills are getting a little carried away also.!Punx0r wrote:....As any technology matures it becomes more effective, more efficient, cheaper and more reliable. It's continuous refinement and improvement.
Going forward a decade or three, stationary storage for $10 or maybe even $1 kWh is likely.
Most of these technical development / cost / time relationships, tend to follow an "Exponential" curve..an bit like "Moores Law" ..they reduce in cost by 50% every few years, as capacity and sales increase ....up to a point where they become "commodity" items.
THEN.. normal market forces take over..Supply vs Demand. ..and that is where the price hits a floor totally unrelated to quality, efficiency, reliability, production costs , material costs , etc.... its just how many are available vs how many are in demand.
They used to say Computers would become ultra cheap, and to some extent they are cheaper than when they were first introduced, but they are not any cheaper today than they were 20 years ago.
How about TVs ? ..they are better , bigger, different, but i bet you paid more for your last TV than you did 20 yrs ago.
More relative, those little AA batteries, are they any cheaper now than they were 30-40 years ago ??
NO ! ...because the market dictates the price,..not the production costs etc.
If batteries ( or PV panels) are a solution to RE power, then there is going to be a very, very, large demand.
Sendler has pointed out a few times the scale of battery capacity required to support a RE grid system, and how impossible that supply task would be, ...so think how that may affect your $1/kWh price.
And the battery manufacturers will also have their own idea of costs for a viable business plan.
