Of course not, because Germany has 100% backup of thermal (Nuclear, gas, coal, biomass) generation capacity, ....However, this report graph below ( touch to enlarge), shows that on that day ..Oct 18th, pm peak time, the German grid had to urgently demand several GW imported for an hour or so to cover the demand peak after wind and solar had faded and conventional sources were already peaking..
This is not true. There is _no_ "urgent need" to import electricty because as you already had written here there is more than enough backup capacity available. import and export do happen because it is cheaper than in-country production or shutdown. A large grid is always a benefit and if you use it, you see an electricity flow alongside that grid. ThaTs# the point of it.
An European country that in reality urgently(!) needs to import because own production capacity can not supply demand is France sometimes during peak hours in strong and cold winters.
up until 80-90% share of renewable energies Germany will keep most of its fossil backup power,because it is needed during some hours a year. Those powerplants do exist, it's "just" a matter of the cosst to keep them available. Yes, the transition of the systsem is not for free.
Comparing electricity prices for consumers has not much to do with production cost of electricity.
This is why consumers pay a lot for electricity in Germany:
Beginning clockwise on top right:
6,88ct EEG Umlage /this is waht is payed for biomass, wind, solar, water & others. It's quite high but around 2-2.5ct of that are older solar plants when solar power was between 30ct to 50ct/kWh, Around 1ct/kWh is old expensive biomass power plants (most of that is hidden subsidizing of farmers) and around 1ct/kWh is old and expensive offshore wind. After around 10 years most of those old power plants will get to the end of their very expensive feed in tarif period and will produce much cheaper or shut down. So what Germanies consumers pay is the very steep learning curve for photovoltaic. Without that 35GW of old solar power plants in Gerany (and parly some other countries) during that tim solar PV would still cost 30ct/kWh and not around 3-10ct/kWh of todays cost. This has little to do with technology improvemnet, but mostly jst econoomies of scale. Someone needed to built that gigafactories and those needed someone to buy thair panels no matter the cost. This is what happend 10 years ago.
Was it worth the cost? I would say yes. Without Germanies consumers payng some billion for old solar power plants China, India & Co today would build coal instead of solar power plants.
0.8ct/kWh Sonstige Umlagen (this is related to RE grind integration and fossil Co generation)
1.66ct/kWh Konzessionsabgabe (this is a "tax" for communities, not realted to RE)
7.48ct/kWh Netzentgelte, Abrechnung (includes mainly the price for our good and well working electricity grid)
5.63ct/kWh Stromerzeugung, Vetrieb (priduction cost + distribution)
2.05ct/kWh Stromsteuer = tax on energy consumption (has nothing to do with RE)
4.66ct/kWh Umsatzsteuer = VAT (has nothing to do with renewable energies)
So electricity has always been expensive for German households. RE is more expensive than it would be for other countries, because we paid much much more for the early GW of solar, offshore wind etc than those cost now. Up to 10 times more in case of solar. This additional cost will start to go away after around 10 years.
What you do NOT see in your tarif is the cost for nuclear power waste management. This is payed from tax money.
What you also do not see is the subsidizing of hard coal during some decades which we stopped doing some years ago (we now just import the hard coal, this is much, much cheaper)
So while transition to RE has some upfront costs, just comparing electricity prices says more or less nothing.
This is a comparison on electricity prices for households vs houshold net income in Europe:
Does it really matter if this is 1.5% or 2%? For saving just 0.5% you want to live in a country destroying the environment and killing several thousand people because of pollution plus making the world a really hot place in the future with maybe billions of refugees? Really? Do you think people in Prybjat or Fukushima would mind to pay 1% more instead of leaving their homeland forever? I clearly know hat I would prefer.
And as I have explanied above the cost for RE is only a part of that extra costs, so in reality it is much less than 0,5% (and it will be even lower with more persons per household)
And btw. the money for those old solar power operators usually does not go to some ultra rich oil and gas people in Russia or Saudi Arabia, but stays within investors in our own country, which I also clearly prefer.
