Electricity, this precious everyday commodity, is both essential and sometimes expensive. In 2025, good consumption management becomes essential. In fact, for certain offers, 22 red days are programmed. These are the days when electricity prices explode and which can cause the bill to skyrocket.

For efficient management of your electricity
To understand clearly, there are three types of days: “blue days”, “white days” and “red days”. These categories are determined by the demand for electricity and, of course, the tariff applied.
On average, subscribers benefit from 300 blue days per year. During these days, EDF applies a 40% reduction on usual rates, allowing you to make significant savings.

However, what subscribers are really concerned about are the 22 red days. These days are the most expensive of the year. In addition, their impact on the electricity bill can be devastating.
The sword of Damocles on your electricity bill
Red days represent the nightmare of households subscribed to the offer Tempo. During these 22 days, prices can skyrocket, especially during peak hours. In fact, the price of electricity can triple compared to a normal rate.

How to prepare for red days?
The 22 red days take place between November 1 and August 31. This is the period when prices explode, making the management of electricity consumption even more crucial.
To avoid unpleasant surprises, a few steps can help limit the damage. For example, lower the temperature of your heating by one degree can have a significant effect on the bill.
Ademe also recommends maintaining a temperature of 19°C in the main rooms and reduce the number of unoccupied rooms. By adjusting your thermostat in this way, you can save up to 15% on your energy consumption.
Furthermore, a thermostat programmable can help you better manage your heating needs. When you program heating time slots, you optimize electricity consumption and avoid unnecessary heating.
Consider using alternative heating sourceslike wood. Also make sure that your water heater only operates during off-peak hours.
Other tips for saving electricity
Electrical appliances play a key role in managing consumption during red days. Ademe suggests lower the water temperature in the water heater to 50-55 °C to limit consumption.
Other small actions can also help reduce the electricity bill. For example, wash laundry at 30°C, unplug unused chargers or even shift the hours of use of demanding devices.
