Checked on 22 September 2026
What TB Gränichen has published for 2027
- Keeps the quarterly average price in 2027.
- Applies from 1 January 2027.
- 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.
