WWZ: feed-in payment from 2027
Checked on 21 September 2026
What WWZ has published for 2027
- Keeps the quarterly average price in 2027.
- No change is announced for 2027.
- Guarantees of origin: 1.00 Rp./kWh on top.
- Negative market prices do not affect you directly with this model.
So for you, probably nothing changes yet in 2027. The figures show what applies once the new rules reach you.

Should you do something?
For this example house: Not yet. Your grid company keeps its current model in 2027, and none of the possible steps pays off for you. Check again when it switches.
