In the Netherlands we now also have a "terugleveringstoeslag" where you have to pay a monthly fee based on the maximum peak power delivered to the grid over the year. At least, the bigger electrical companies already have it, the rest will soon follow. My coworker (who has way too many solar panels installed) got a letter from Essent that he had to pay 67 euros monthly starting October. So he switched companies, but he'll have to figure out something else next time.
