Feed-in costs
Feed-in costs are charges an energy supplier applies for processing the electricity you export to the grid.
What are these charges for?
They cover the supplier’s cost of handling exported electricity, and they are billed to you separately from the feed-in payment you receive for the same units.
Not every supplier applies them, and the structure varies: some charge a flat monthly amount, others scale the charge with the volume you export.
Are suppliers free to set them at any level?
No. They may only reflect costs the supplier genuinely incurs in processing exported power, which rules out treating them as a general surcharge.
That constraint is what makes them comparable between suppliers. Ask about them explicitly, because they rarely appear on the first page of an offer.
Do they disappear when net metering ends?
No. They continue unchanged after 1 January 2027. Ending net metering changes how exported units are valued, not whether a supplier may charge for processing them.
For any calculation covering the years after 2027 they are a fixed line, and one of the few that does not move with how much you generate.
Can I reduce them?
Where the charge scales with export volume, consuming more of your generation on site reduces it directly. Shifting flexible loads into daylight hours is the practical lever.
Where the charge is a flat monthly fee, consumption patterns make no difference and the only remaining lever is switching supplier.
Common questions
Does every Dutch supplier charge these?
No. Whether they apply, and in what form, differs by supplier and by contract. Ask directly when comparing offers, since they are seldom presented prominently.
Are these the same as grid charges?
No. Feed-in costs come from your energy supplier and relate to processing exported electricity. Grid charges are paid to your network operator for the connection itself and are unaffected by having solar panels.
Will they still exist after 2027?
Yes. The end of net metering on 1 January 2027 does not remove a supplier’s ability to charge for the costs of processing exported electricity.
