December 3, 2024 marks a key milestone for subscribers to EDF's Tempo offer: the first red day of the season. This system, which is distinguished by particularly marked price variations depending on the time of year, reflects the complex energy issues facing France.
EDF Tempo: a changing electricity price
The Tempo option, introduced by EDF to encourage more responsible consumption, is based on a segmentation of the year into three categories of days: blue, white and red. The latter, 22 in number per year, are triggered during the winter period, when electricity demand peaks. For subscribers, the cost per kilowatt hour then skyrockets, reaching 0.76 euros during peak hours, almost seven times more than during blue days.
For EDF, the objective is twofold: reduce consumption peaks and maintain the stability of the electricity network, particularly in winter, when heating, household appliances and lighting place heavy demands on the infrastructure. Red days, triggered according to weather forecasts and the expected load on the network, serve as a lever to smooth usage and limit the risks of overload. This Tuesday, December 3, the cold wave announced in several French regions, combined with limited availability of certain power plants, fully justifies this decision. However, the implementation of this pricing policy gives rise to debate.
Households more affected than others
Households subscribing to the Tempo offer find themselves at the heart of the tension between regulation and constraint. In rural or peri-urban areas, where electric heating predominates due to a lack of alternatives, red days represent a significant financial burden. A household consuming 15 kWh during peak hours will therefore have to pay nearly 11.40 euros for a single red day, compared to barely 1.80 euros on a blue day. This situation requires significant adjustments, whether by reducing heating, postponing the use of household appliances or adopting energy conservation strategies.
However, not all households have the same room for maneuver. While some can invest in more efficient equipment or use alternative heating solutions, others, particularly among low-income households, are bearing the brunt of these price increases. Criticism of EDF is increasing, denouncing an approach which, although technically justified, disproportionately penalizes the most vulnerable.
Manage electricity demand and consumption peaks
Beyond the immediate social impact, the red days raise questions about the long-term management of energy demand in France. While climate ambitions require a reduction in CO2 emissions, in particular through the promotion of carbon-free electricity, the dependence on winter consumption peaks illustrates the limits of the current model. EDF, faced with a gradual increase in Tempo subscribers and growing consumer awareness, must also face criticism of the lack of transparency. The red days calendar, announced only the day before, leaves subscribers little time to organize their uses.
This first red day of the season will not be the last. If cold temperatures continue, more similar days could follow in the coming days, up to a maximum of five consecutive red days during the week.
While December 3 promises to be marked by restrictions for some and adaptations for others, a question remains: is France ready to reconcile its climate objectives with the daily needs of its citizens?
