Primeo Energie raises electricity prices by 42% for fixed-price customers in France from 1 February 2027

Primeo Energie, an electricity supplier headquartered in Switzerland and active in the French residential market, has begun informing customers on fixed-price contracts that their current price expires on 31 January 2027. From 1 February, unless they act, their contracts will switch automatically to the “Fixe Sereine” offer, according to letters quoted on 6 November by the comparison site Selectra.

The figures. For a 9 kVA subscription, the base-option kWh rises from €0.1735 to €0.2464 including taxes, the peak-hour kWh from €0.1802 to €0.2559 and the off-peak kWh from €0.1446 to €0.2053. The monthly subscription goes up from €19.26 to €27.35. Primeo puts the increase at 42% of the annual bill including taxes; in the example given in the letter, a customer using 15,507 kWh a year pays €1,177.96 more per year. Selectra calculates that a base-option customer using 6,000 kWh a year would pay about €1,807, compared with €1,272.

The stated reason. The supplier says wholesale electricity prices doubled in 2026, rising 157% between January and October. The new offer’s prices excluding taxes stay fixed until 31 July 2029, according to Primeo’s product sheet; network costs, taxes and levies can still change. Selectra notes that market prices quoted for 2028 and 2029 are lower than those for 2027.

What customers can do. The offer has no minimum term: Primeo’s product sheet states it can be cancelled at any time, free of charge and without justification. Selectra points out that the supplier must announce the change at least one month in advance, that switching supplier takes no more than 21 days without any interruption of supply, and that a return to the regulated tariff is possible at any time, including after 1 February.
