On February 1, 2025, regulated electricity prices in France will decrease by 15%… but will increase by 8% for fixed offers.
If you move forward and then backward, how do you expect… anyone to understand anything? This is essentially the feeling conveyed by the Government, which, through an announcement effect, promised an average decrease of 15% in electricity prices in France on February 1, 2025. This particularly affects subscribers to the Blue tariff from EDF. However, for those who have a fixed offer, two taxes will revert to pre-war levels in Ukraine and will increase the bill by 8%.
Let’s quickly calculate to better understand the situation, taking as an example a Tesla Model Y Propulsion with a 60 kWh battery.
Cost of home charging
Case of a subscriber to the regulated EDF Blue tariff:
- Before the decrease: average charging cost = €15 (0.2516 €/kWh).
- After the decrease: average charging cost = €12.82 (0.2138 €/kWh).
Thus, for a range of about 400 km in mixed cycle, a Tesla Model Y driver will save about €2.18 per charge. Over an annual distance of 10,000 kilometers, the savings will be approximately €54.5.
In the case of a subscriber to the EDF Blue Full Hours / Off-Peak Hours tariff:
- Before the decrease during Full Hours: average charging cost = €16.20 (0.2700 €/kWh).
- After the decrease during Full Hours: average charging cost = €13.77 (0.2295 €/kWh).
Here, the savings are €2.43 per charge, because a -15% decrease from an initially high tariff amounts to a larger value. Over 10,000 km, the gain is €60.75 assuming you only recharge during full hours… which happens rarely.
- Before the decrease during Off-Peak Hours: average charging cost = €12.40 (0.2068 €/kWh).
- After the decrease during Off-Peak Hours: average charging cost = €10.54 (0.1757 €/kWh).
Low price = small savings. Here, the gain drops to €1.86 per charge, or €46.5 for 10,000 kilometers.
Finally, there is no tangible reason to believe that Tesla will lower its charging prices in its network of Superchargers. As a result, long trips remain expensive.
