As you probably know, with the energy crisis, the government put in place a price shield to help slow inflation around electricity prices. Instead of an increase of 40 to 100%, according to some estimates, prices have increased “only” by an average of 15% 1^Er February 2023

Unfortunately, the tariff shield will not be able to operate forever. Indeed, the government has just announced that the regulated tariff for the sale of electricity will undergo a new increase from 1^Er next August, p an initial increase of 10% on average.depending on the contract.

Refueling with electricity at home will still be profitable

At the time of writing this article price per kWh is €0.2228 including tax during peak hours and €0.1615 including tax during off-peak hours for a capacity of 6 kVA if we take the blue tariff that applies to more than 25 million households in France in 2023. With an average increase of 10%, therefore we can expect a tariff per kWh of €0.2451 during peak hours and €0.1777 per kWh during off-peak hours. At the moment these are our own estimates based on what the government has announced as the exact price is not yet known.

Taking a consumption of 18 kWh per 100 km in an electric car (this is the relatively average consumption we have noted in mixed use in many recent electric car tests) we reach a cost of €3.20 in off-peak hours per 100 km for electric vehicles and €4.41 in peak hours for the same use. Under the old tariffs, it was 4.01 euros per 100 km in peak hours and 2.91 euros in off-peak hours.

Another example is perhaps more revealing. If you charge your Tesla Model 3 Propulsion from 10 to 80% with a 60 kWh LFP battery, you will need 42 kWh. This gives us 10.29 euros in peak hours under the new tariffs and 7.46 euros in off-peak hours. Under the old rates, this was €9.36 in off-peak hours and €6.78 in off-peak hours.

We have taken the example of a basic contract that applies to most French people. With other contracts, in particular for professionals, prices may obviously vary.

What about public charging stations?

Regarding public terminals, it is the suppliers who will adapt their prices. Changes in the tariff schedule may not happen immediately, as there will of course be some inertia between the introduction of new electricity tariffs by the government and adaptation by suppliers.

Fast charging in public terminals is much more expensive than at home, so you need to watch the prices. For example, at Ionity, the tariff can now reach 0.69 EUR/kWh. So if we take the example of our Model 3 Propulsion and recharge from 10 to 80%, this gives us a charge of €28.98.

It remains to be seen whether there will be an immediate increase in the number of suppliers, as the government has created an “electric shock absorber”, a kind of price shield for businesses and communities, which also applies to charging stations. so that refueling is not too expensive.
