Since February 1, 2024 and the rise in electricity prices, the kilowatt hour has never been so expensive when leaving a domestic socket. However, on the markets, the price of energy is falling. Enough to lead Tesla to once again reduce its prices at its charging stations. As a result, filling up at the Supercharger sometimes costs less than at home, and above all is much quicker! Enough to make home charging obsolete.
With the removal of the price shield, French households have had to deal with an increase in the price of electricity at home since February 1, 2024. However, the wholesale price has returned to pre-crisis values. As a result of all this, if the price does indeed increase at home, it falls at public charging stations. At least at Tesla.
New significant drop
In mid-January, users of Tesla Superchargers (SUC) were indeed pleasantly surprised to discover that the price at the terminals had fallen. Indeed, several European countries have benefited from big discounts of between 2% and 17%. Only countries like Sweden and Norway saw their prices increase by 25%. In France, the drop is around 16%, with certain stations now displaying a price per kilowatt hour (kWh) identical to that paid at home, to the nearest cent. This adjustment comes after that of May 2023, where sharp declines had already been observed. We know that the American manufacturer tends to follow the price of spot electricity to change its prices downwards or upwards.
€0.26 per kWh
It is important to note that the price per kWh charged on Superchargers can be different depending on the time of day, with peak hours from 4 p.m. to 8 p.m., and off-peak hours the rest of the time. By charging at the Montpellier station at 2 p.m. for example, the price (0.26€/kWh) will not be the same as at 6 p.m. (0.29€/kWh). The price also differs from station to station. Tesla doesn’t really give an explanation as to why and how, but we can imagine a desire to direct towards one Supercharger rather than another depending on the number of steles present for example, or because the rent in certain locations is more expensive than others… Thus, although separated by only 15 km, the Parly 2 station has a price of €0.38 during off-peak hours and €0.42 during peak hours, when that of Vélizy 2 is at respectively €0.26 and €0.29. It is obviously possible to consult the prices of each station before going there via the Tesla application.
Finally, a Tesla owner will not pay the same price as an owner of another brand, unless the latter has subscribed to a monthly subscription of €12.99. Note that today, more than two thirds of Superchargers are open to everyone in France. Despite these differences, it is therefore possible to pay €0.26 per kWh most of the time, and on most Superchargers. However, with such a price, fast charging sometimes becomes more advantageous than charging at home!
Cheaper than at home?!
Imagine, you have subscribed to the off-peak hours option of the EDF blue tariff and, due to lack of anticipation on your part, you need to recharge during the day to make a trip in a Tesla Model 3 Propulsion in the evening after teleworking. Under these conditions, a 20 to 80% will cost you 9,40€ (34.8 kWh x 0.2700€) without counting the losses at the expense. However, the same charge on a Supercharger during off-peak hours could have cost you 9,05€ (34.8 x 0.29). In other words, in this situation, better to charge with SUC! If you had been able to charge during off-peak hours at home, or charge on the SUC during peak hours, on the other hand, you would have been better off charging at home.
If you have subscribed to the Basic option, the regulated kilowatt-hour rate at home is now 0,2516€. In other words, less than a cent separates this price from that of most off-peak Superchargers. At this price, recharging then costs 8,76€, or only 29 cents less. Over one year of use and 20,000km, this represents a difference of €24.36. The cost per 100 km is 12 cents cheaper. You will find all the comparisons in the tables below.
In most cases, charging at home is therefore still advantageous. But for the vast majority of consumers who have the EDF Base option, this no longer matters much. In fact, to maintain a real difference, a change of subscription is necessary. This is the case of the Tempo option which allows you to save up to 36% on your electricity bill.
Here is the miracle cure for the rise in electricity prices on February 1, 2024
Much faster !
In addition to the price argument which, as we have just seen, can go in favor of Superchargers if you subscribe to the off-peak option and recharge during the day, there is also the time argument. However, we know, for many, Time is money. According to our charging time simulator, it takes more than 9 hours to achieve 20-80% on a reinforced domestic socket in the case of a Tesla Model 3 Propulsion. On a 7kW charging station, this drops to 4h40. In any case, it is out of all proportion to the 16 minutes necessary for a Supercharger to perform the same exercise. This is where its main advantage lies, by considerably reducing charging times during long journeys. And if on a daily basis charging at home is generally done during hidden times, namely at night, we can still prefer fast charging to save time in certain situations, and all the more so if the latter is at same price, or almost. We will still remember that it is less stressful for the battery to recharge at slow speeds, especially in cold weather and when there has been no pre-conditioning.
To conclude, as with the price of its models, Tesla is therefore lowering the price of charging at the start of 2024. Of a price war on electric cars, we are perhaps witnessing the beginnings here. from that on recharging. For the moment, Ionity, Fastned and the others have not reacted…
