You may not have missed it, but a little reminder is always welcome: this Wednesday, February 1st, regulated electricity prices will increase by 15%. It is no longer a price hike that will go unnoticed as it affects 20 million French families as well as several hundred thousand businesses.

What is the increase for electricity?

After a 15% increase in gas prices in January, it is the turn of electricity to increase in February. The increase will also be 15% as planned by the government as part of the energy tariff shield. Although this 15% increase may seem high, it is much lower than the actual increase in electricity. Without the energy shield, one would expect a 35-100% increase in electricity tariffs.

The increase is valid for three main offers, the base offer, the peak hour (HP) and off peak (HC) system operated offer and finally the offer Temp Sold by EDF. Obviously we are talking about regulated tariffs, it is important to refer to the specifics of your existing electricity contract.

FYI, depending on your annual electricity consumption and the capacity of your meter, it is necessary to consume between 35-50% of electricity during off-peak hours HC/HP offers to be profitable. We explain how to choose the most interesting offer according to your environment.

Tempo prices

With the Tempo option, prices depend on the color of the days, blue, white or red. You should definitely avoid charging your car with HP (€0.6712 per kWh) on red days. These days, remember to charge during off-peak hours, otherwise the option Temp loses all interest. Indeed, electricity is cheaper than the regulated tariff most days of the year, but for 22 days the tariff is exorbitant.

What is the price increase for charging a car at home?

It should be noted that the charge of an electric car is calculated based on the cost of electricity per kilowatt-hour (kWh). Of course, electric car fuel consumption varies by model, your driving style, weather conditions, the route you’ll take… There are many variables to consider. So we will buy it An average of 15 kWh per 100 kilometers in our calculations.

For example, for a Tesla Model 3 (Driver, 60 kWh at LFP), the charging value is between 10 and 80% (this is recommended to optimize the charging time), which means that 42 kW must be recovered. Note that this calculation is the same whether you have a dedicated charging point or simply plug your vehicle into a household outlet.

Before February 1 From February 1 Costs to restore 42 kWh Cost per 100 km (15 kWh on average) The price difference is 100 km Evolution
Main Variant €0.174 €0.2062 €8.6604 €3,093 €0,483 18.51%

HC red tariff option €0.1222 €0.1216 €5,1072 €1,824 -0.009 euros -0.49%

The table above includes all the calculated figures, the last column compares the increase in price per 100 km covered with an average consumption of 15 kWh. Obviously, these figures refer to home charging, which is the most commonly used charging method.

Also increases for public additions

The price increases also apply to private and public terminals, despite the fact that the energy shield has been extended to the last. Prices are going up everywhere. Although some companies have lowered prices in recent weeks due to a slight drop in electricity prices, they are still too high for most.

As expected, Tesla increased the prices of its Supercharger devices at the end of January 2023, which will be available on many networks, including Western cargo as you can see below.

So expect an increase in the prices of public terminals, as well as private terminals of large networks (Allego, Ionity, Fastned, Tesla, etc.). It’s interesting to see if the top-up cards are interesting.

One service is trying to simplify this whole jungle of electric vehicle charging: Chargeprice. Based on information provided by the public in addition to the charging operators, Chargeprice lists the tariffs applied by the various electric mobility players at each terminal where it is possible to pay with its services.
