Under the formula in the ministerial decision, they follow the previous month's wholesale price. In October the average wholesale price was about 197 euros per megawatt-hour, up from 156 in September and about 110 in October 2025: the highest since December 2022.
The prices the suppliers published on 2 November, in cents per kilowatt-hour:
- Heron: from 14.76 to 25.95 (+75.8%)
- Protergia: from 18.4 to 26.4
- NRG: from 25.9 to 33.4
- Volton: from 27.36 to 36.22
- PPC (ΔΕΗ): from 15.9 to 16.9 in the first band and from 22.0 to 28.4 in the second (the first band is the first 200 kilowatt-hours of the month)
In 2022 the state subsidised electricity bills. No subsidy has been announced for November and December; the government points to the fixed-price ("blue") tariffs.
