New rules for feeding in self-produced solar electricity worry micro-producers. In the future, they may have to pay a grid fee when they sell their surplus.

"A new grid fee would kill the incentives to invest in solar cells," says micro-producer Jens Fellke in Rumskulla in Vimmerby municipality. Eon has decided not to introduce any new fees for the time being, but Ei's decision creates concern and uncertainty among micropro producers.
