I completely missed your response, thanks for the links. I may come back later to the first one but I will comment on the second.
1) A great influx of cheap wind energy does pose a challenge to the grid as it can, as pointed out, currently not matched to demand due to a lack of grid integration and storage. Cheap German energy exports means of course overall cheaper electric prices for the Polish market however less profit and more challengers for the Polish utilities and it's providers.
Poland gets powered by coal which is also mined by a fairly large amount of people.
Coal plants tend to compete with wind as base load so suffer often especially if cheap wind pushes the (upper) rest of the supply/cost curve towards the right. So there is certainly a lot of specific political interest to keep cheap energy out.
2) The Verbund will also suffer from the wind competition with it's plants along the Danube for example, however I guess that they hope for more business for their investment into the grid and their pump storage plants. They also divested fossil fuel lately as it was mostly not competitive under current condidtions.
Of course the Austrian consumer should be happy - just like the Polish one - about German electricity lowering his bill.
