I keep asking PV tech people what the term is, but no joy so far.
Nationwide in Germany, height of summer at midday, and low consumption
of electricity , they have to dump electricity, which is not possible AFAIK.
What they do is pay a fortune, whether required or not, to neighbouring
countries to divert this surplus immediately to consume the excess.
At least they do know the weather sufficiently in advance, to arrange
this on the day, so no actual surprises
