Feed-in costs must be shown the same way on every invoice from 2027
By Stefan Douw · Maker of Stekkerkompas
The Ministry of Climate and Green Growth has opened a consultation on an amendment to the Energy Regulation that requires energy suppliers to show feed-in costs (terugleverkosten) the same way on every invoice. The internet consultation runs until 10 July 2026. The rules take effect on 1 January 2027, exactly when the net-metering scheme (saldering) ends.
What changes
Right now suppliers charge feed-in costs in all sorts of ways: a fixed monthly amount, tiers based on how much you generate, or a rate per kWh. That makes offers almost impossible to compare. From 1 January 2027 every supplier has to state these costs on the invoice in the same form, as a fixed amount per exported kWh. When making an offer, suppliers must also clearly explain how they calculate the figure.
Payment and costs stay separate
A key point in the proposal: the feed-in payment you receive may not be netted against the feed-in costs you pay. The two must stay visible separately, so you can see what your exported power actually nets. The consumer authority ACM will monitor compliance.
Why it matters to you
Once net metering falls away, exporting pays far less than self-use, and feed-in costs can flip a positive payment into a negative balance. Until now those costs often disappeared into the fine print. With one fixed unit on the invoice, you will be able to put suppliers side by side and see which contract costs you the least.
What it means for your numbers
The rule changes how the costs are shown, not how high they are. Comparing stays your job: the amounts vary a lot between suppliers. Run your own numbers in the calculator and see what exporting and a home battery earn in your situation after 2027.
