Still little known a few years ago, the EDF TEMPO subscription tends to convince more and more consumers who see it as a way to save money on their bill. And although it is the offer that increases the most on February 1, 2024, it remains the most interesting in many cases.
When the price of electric cars falls, the price of electricity increases! As you know, each year, the regulated electricity sales tariff is generally revised twice, in February and August. But since 2022, the increases have been felt more than usual. The cause is the war in Ukraine and the explosion in energy prices. Fortunately, the government’s implementation of the price shield had greatly helped to limit bills. The fact remains that between the end of 2021 and the beginning of 2023, households were able to observe an increase of 46% of the base price per kilowatt hour (kWh). Today, with the energy market having become reasonable again, the executive has decided to put an end to the shield by gradually re-increasing certain taxes, in particular the TICFE, the domestic final consumption tax on electricity. As a direct result, the price of electricity increases on February 1, even as the price of energy decreases on the wholesale market, thereby delighting alternative electricity suppliers not subject to the regulated tariff.
Update on new electricity prices (February 2024)
According to the words of Bruno Le Maire made on January 21, “for 97% of French households, the increase will be below 10%”, twhile specifying that there would be no “no further increase in 2024” and that the “next would take place on February 1, 2025”. In fact, here are all the new regulated electricity prices calculated by Selectrafrom the different options of the EDF Blue tariff intended for individuals.
If the increase in the price of the kWh of the Base option is slightly greater than 10%, a variation similar to the previous increase, we especially notice that unlike August 2023, the Tempo option is the one that increases the most. This is explained by the very nature of the TICFE which is a tax levied on consumption. In this case we are talking about excise duty. This tax is fixed on each kWh consumed, which means that the cheaper the kWh was, the higher it will suffer a percentage increase, and vice versa. Thus, the price per kWh for the TEMPO option during off-peak hours on blue days varies from +22,73 % when that for the HP/HC option only increases by +9,76 %. Note that to arrive at these conclusions, Selectra based itself solely on an increase in excise duty. In other words, the prices which will be published in the Official Journal on February 1 may vary slightly, without this influencing the different trends presented here. Let’s now look at the impact of this increase in the case of home charging.
What are the consequences of recharging an electric car?
The rise in the price of electricity affects all French households, but owners of electric cars will, a fortiori, be particularly affected. An increase of 10% logically represents a greater impact on the bill for those who charge their car at home. We therefore brought out the calculator in order to concretely assess the consequences of these new prices.
Take the Tesla for example. Model Y, the best-selling electric car in France in 2023, and even the best-selling vehicle in Europe, all engines combined. In its propulsion version, its useful 58 kWh battery (60 kWh in nominal) allows you to cover around 400 km on a mixed route in real conditions. 20,000 km per year thus require 50 complete recharges (i.e. 2900 kWh without taking into account recharging losses). Under these conditions, here is a summary table of the consequences of the increase on charging prices, depending on the different options of the EDF Blue tariff.
The annual cost of recharging with the Base option therefore amounts to €730 (58*50*0.2516), i.e. 3,65 €/100 km. For comparison, it is 10,50 €/100 km for a petrol vehicle with a consumption of 6 l/100, and whose price per liter is €1.75 at the pump. In terms of “full”, we see that a 58 kWh recharge now costs €14.59, when it was previously €13.20. So it’s €1.39 more. At the end of the year, this represents a difference of almost €70the equivalent of an additional expense of 19 cents per day attributed to the electric car.
But what we also notice with this table is that the variations are identical, regardless of the option purchased. Once again, this is explained by the very nature of the TICFE. What is also interesting is to ask yourself what would happen if you changed your subscription today.
We had already devoted a complete article to the Tempo subscription during the August 2023 increase. If you would like to have details of how it works as well as its limits, do not hesitate to consult it.
This little-known EDF subscription allows you to save hundreds of euros on charging an electric car
As far as we are concerned, let’s look at the direct impact on the bill if you decide to modify your subscription* switching from the basic option to the Tempo option. Taking the example of the Tesla Model Y traveling 20,000km over one year, the total cost at the end of January 2025 will therefore be 908 € (€730 recharge + €178 annual subscription). Now let’s compare this figure with the cost obtained by subscribing to the Tempo option. As the latter has differentiated prices depending on the color of the days, to simplify the calculations, consider that recharges are carried out at night and regularly throughout the year. We can then assume that 41 recharges are made during off-peak hours on blue days, 6 recharges during off-peak hours on white days, and 3 recharges during off-peak hours on red days.
By following this schedule, the addition would then amount to nearly 571 € (41x58x0.1296+6x58x0.1486+3x58x0.1568+183.96), subscription included. In other words, by changing your subscription, not only do you not feel the increase on February 1st (+€70), but you even save 337 € (908-571) about recharging this Tesla Model Y!
The same exercise can be carried out to compare the Off-Peak option with the Tempo option. In this case, we arrive at a difference of 220 € in favor of the Tempo option. Note that even by recharging during peak hours on blue and white days, and during off-peak hours on red days, you still benefit from the Off-Peak Hour option with nighttime recharging.
Thus, even if unlike the increase that occurred in August 2023, the Tempo rate is the one that increases the most, it still saves money compared to other options (up to – 37% on the base price in the example presented). We can nevertheless regret that it loses a little of its attractiveness given that it is the one which most encourages sobriety in the event of high demand on the electrical network. In any case, what are you waiting for?
* For the calculations presented, we based ourselves on a 9 kVa power subscription.
