At the bottom of the post is some commentary on the way hydro and also some kinds of gas rapidly responded to compensate for short-term falls in the wind and brown coal yesterday (Sunday 24).
Prolonged wind drought and freezing cold drives German power supply to the brink. Read all about it!
Soviet shortages led to the gag about “what has 100 legs and eats cabbage?” 50 Muscovites lining up to buy sausage.
Wind and solar obsessed Germans must feel a little like the USSR’s (unwilling) vegetarians at the moment.
Their endless seas of solar panels are plastered thick with snow and ice and, accordingly, producing two fifths, of five eighths of very little.
And their 30,000 wind turbines have downed tools, too. With bitterly cold, dead calm conditions across the country, wind power output has been reduced to an occasional trickle.
Power rationing is the only thing that’s preventing a total collapse of Germany’s grid; during the first week of January the country narrowly avoided widespread blackouts following the total collapse in wind and solar output.
But, if you relegate engineers to the status of well-meaning idiots, and supplant them with green ideologues with gender studies degrees, get ready for chaos. Which is precisely where ‘green’ energy obsessed Germany now finds itself.

Check out our supply of RE at present.
At 6pm NSW time the wind is delivering 4% of the power supply with the mills turning over at 15% of capacity. The sun is fading fast and the coal clunkers are delivering 70% of the power approaching 90% of capacity.
This is the live display, so check the time.
There will be trouble at sunset without conventional power. Order your generator now.
To see the supply and demand through the day, see this display at the Aneroid site.
Around five on Sunday afternoon the demand was almost 34GW, not far off the 36GW registered on19 Jan 2019 when there were blackouts in Victoria. It was adjusted downward later, probably by recalculating the estimate for rooftop solar.
At the peak conventional power contributed over 80% and the wind added less than 4%. You can tick and untick the boxes under the live display to see the contribution of the different sources. There were interesting blips in the hydro contribution at 12 and 17.
Just before noon the wind supply dropped steeply for half an hour and then recovered in the next half hour. That is the bane of the life of the grid controller and Tony from Oz has made an important study of these events that are more common than people generally realise. The hydro supply adjusted to compensate. Approaching 17 (5pm Queensland time) there is another spike in hydro to compensate for a dip in the brown coal supply.
The rise in hydro was much larger than the fall in brown coal for reasons unknown to me. Ignore the cursor and the lines attached to it, I should have left it out or located it at the point of interest. There was another matching rise and fall of wind and brown coal between 7 and 8 in the morning.
Various forms of gas were ramping up and down rapidly at times, some of them are minor players but they make a difference at the peak. Too much to explain without a lot of ticking and unticking of boxes:)
