450 million euros nationwide. This is the annual additional cost due to “this absurd situation and real malfunctions in pricing” explains Vincent Maillard, co-founder of Plüm Énergie in the columns of La Dépêche.

What is the problem ? The “peak/off-peak hours” option in energy supplier contracts.

The operation is nevertheless advantageous. The supplier’s subscription is slightly higher than the basic rate when it comes to “peak hours”. On the other hand, “off-peak time” is less expensive. This was originally intended to partially offset electricity consumption outside of energy peaks.

“Several years ago, this offer was interesting if we managed to deport 30% of consumption to off-peak hours”, comments Frédérique Feriaud, director general of the services of the National Energy Mediator. However, in 2016, the rates increased. To the point where the principle of “off-peak time” is no longer viable.

“Today, it is only interesting if 50 to 60% of consumption is shifted to these hours. However, it is very difficult. Prices have increased and consumption patterns have changed,” he explains. she.

However, the director reassures: “if someone works outside and lowers his heating during the day, if he can enslave his water heater and run his washing machines and his dishwasher during off-peak hours. .. it can be interesting.”

So don’t make the mistake of consuming at peak times. Make the most of the times when electricity costs less. The option can be economical… Provided you use it well.
