It was one peak moment during a time of low usage at night with simultaneous strong winds. Assuming this is about the July 2015 moment (which CleanTechnica seems to be hiding

or even completely ignorant of).

So yes those 40% surplus were automatically exported (the European power market is integrated), but no that didn't move the needle on consumer prices.

Exported only if the grid needs it.

I'm still wondering what you might have meant by this.

If you produce 40% over current usage you have to get rid of that 40% immediately. For a small country with no appreciable amount of pump storage they could quickly spin up this must mean mostly by export. Otherwise the frequency rises sharply above the 50 Hz such that substations start dropping like flies.

In other words it seems obvious to me that the grid needs it.
