SIG: feed-in payment from 2027
Checked on 21 September 2026
What SIG has published for 2027
- Pays a fixed price: 10.96 Rp./kWh.
- No change is announced for 2027.
- Negative market prices do not affect you directly with this model.
The calculation uses this fixed price. The 2027 rules then do not change your payment.

Should you do something?
For this example house: No. Your grid company pays a fixed price, so the 2027 rules do not change your payment. And none of the possible steps pays off for you.
