Electricity price in September 2026: where do we stand?
What is the price of electricity in September 2026? The “Tarif Réglementé de Vente d'Électricité” (regulated electricity sales tariff), also known as the “tarif Bleu”, recorded a slight decrease in February 2026. These changes have a direct impact on your bill. Here are the explanations, figures and examples to better understand what you are actually paying for.
Article summary
- The Regulated Electricity Tariff stands at €0.2001/kWh incl. tax in September 2026 under the Base option.
- It fell by around 15% in February 2025, followed by a further 3% decrease in August 2025 and a 0.62% decrease in February 2026, before rising by an average of 2.5% on August 1, 2026.
- Since the revision in August, the Regulated Electricity Tariff has remained almost stable, with no significant impact on the bill.
- The decrease is limited by taxes and network costs.
The regulated electricity tariff for residential customers, also called the “tarif Bleu”, is set by the French public authorities following advice from the “Commission de régulation de l’énergie” (CRE – the French Energy Regulatory Commission). This tariff therefore serves as the benchmark for several million households in France.
After two years of sharp increases linked to the energy crisis, the Blue Tariff fell significantly in 2025, followed by a very slight decrease in February 2026 (less than 1%). On August 1, 2026, it then increased by an average of 2.5% incl. tax. In this article, we take a closer look at how the tariff has changed throughout the year and what this means for your electricity bill.
In September 2026, the price per kWh under the Regulated Electricity Tariff is €0.2001 under the Base option, €0.2142 during Peak Hours and €0.1589 during Off-Peak Hours.
For example, a household using 4,000 kWh per year under the Base option would see its annual bill decrease by around €206.40 (calculated between August 2024 and August 2026, excluding the subscription fee).
Despite the average 2.5% incl. tax increase that came into effect on August 1, 2026, the Regulated Tariff remains below its August 2024 level.

How has the price of electricity evolved up to now?
On August 1, 2026, the Blue Tariff increased by 2.5% incl. tax, following an average 15% decrease in February 2025, after successive increases of 10% in August 2023, 15% in February 2023 and nearly 9.8% in February 2024.
The revision of 1 February 2026 was moderate, with a slightly lower price including tax. This trend reflects the balance between falling energy prices and rising fixed costs.
Why isn’t my bill really going down in September 2026?
Even if the price per kWh decreases, other factors may limit the reduction in your electricity bill:
Accise sur l’électricité (an indirect tax levied on the sale or use of energy products): restored to €33.70/MWh in 2025
TURPE (network transport and distribution tariff): increased by 7.7% to finance the public electricity grid
The actual gain is therefore lower than the sole decrease in the price per kWh, but it remains noticeable.

Overall: around €230.40 in savings compared to 2024 for a consumption of 4,000 kWh, despite summer stabilization.
The year 2025 was favorable for individuals subscribed to the “tarif Bleu”. February 2026 marks a stabilization with a 0.62% decrease. To better anticipate your consumption and optimize your bill, it remains important to monitor the biannual revisions and choose the tariff option best suited to your consumption profile.
The “tarif Bleu”: what is it and who is it for?
The “Tarif Réglementé de Vente d’Électricité” (TRVe), or “tarif Bleu”, mainly applies to private individuals and small sites connected at low capacity (≤ 36 kVA). The tarif Bleu does not only correspond to the price of the electricity consumed. It includes several components that make up the final price:
- The cost of producing and purchasing electricity
- Transport and distribution through public networks (TURPE)
- Supplier operating costs, for contract management and customer service
- Taxes and contributions, such as VAT and the electricity excise
The tariff is revised twice a year, in February and August, which explains why the price may vary throughout the year.
Review of electricity prices in 2025
The year 2025 marked a normalization of the market, offering households better visibility on their electricity bills.
Major decrease in February: the largest of the year
Stabilization in August: the price including tax remained almost identical
Real savings: significant, but limited by taxes and network costs
Why did the price of electricity decrease in 2025?
The significant decrease (around 15% including tax) recorded on 1 February 2025 mainly resulted from the drop in electricity prices on wholesale markets after the peak of the energy crisis. The market is normalizing, making it possible to pass this reduction on to the end consumer.
What is the Regulated Electricity Sales Tariff (TRVe)?
Also called the “tarif Bleu”, it is a benchmark price set by the French public authorities, following the opinion of the “Commission de régulation de l’énergie” (CRE). It applies to residential customers and small businesses. It includes four main components: the cost of energy (production/purchase), transport and distribution costs (TURPE), commercial costs, and taxes/contributions.
Why does the price of electricity change regularly?
The price varies for two reasons:
Global markets: gas and coal prices, as well as the availability of the French nuclear fleet, indirectly affect the cost of purchasing electricity.
Regulatory revisions: the TRVe is revised by the French government twice a year, in February and August, and the network cost (TURPE) is generally adjusted each year.
What is the difference between the price per kWh and the electricity subscription?
The subscription: this is the amount paid each month, regardless of your consumption. It mainly depends on the subscribed capacity of your meter, expressed in kVA.
The price per kWh: the unit price of the electricity you actually consume. It represents the largest part of your electricity bill.
