Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

BTW, today was a particularly good day for renewables in Germany, with well over half of peak power supplied. (Possibly a new record in percentages?)

Possibly a new record in percentages?

Yes:

...on last Sunday, 16 June 2013, for the first time the wind and solar power plants in Germany accounted for a record amount of more than 60 percent of the necessary national power supply capacity. The previous peak value, 59.1 percent, was registered a day before, on Saturday, 15 June 2013.

An article on a German-language energy blog highlights the unsung component of Germany's supposed grid crisis: excess production from traditional plants. During this day, fossil-fuelled power plants contributed 17 GW at the time of the peak load (that is not all mid-merit plants were throttled), against some 6.3 GW of exports.

Great article DoDo... and 144 tons saved in one day!

I now think the author made a mistake, though: I believe 17 GW should be all conventional plants (including nuclear).

Hm, and as there are some 12 GW of nuclear capacity still working, that would be most of it

Upon checking, Grafenrheinfeld and Philippsburg 2 were off-line that day, leaving 9,391 MW of net power (9,883 MW gross) if operated full-throttle.

Eh, the author made a much bigger mistake: if you do the sums you'll see that the correct answer is 1000x larger, more like 144 000 tons!

Those kilos, megas and gigas are a bitch :-)
