Since the 2000s, the French electricity market has gradually opened up to concurrency. First of all, it should be remembered that before that EDF-GDF was a fully integrated group and had a monopoly since 1945. From production to the supply of electricity to its customers. In other words, all French consumers paid a rate regulated by the State.
Today, all customers (from residential to industrial sites) have the possibility of subscribing to a “market” offer. The regulated tariff still exists, but today any company can subscribe to an offer competing with that From EDF. The questions that can be asked are the following: how do you simply change the electricity supplier? What are the associated risks? And above all at what price?
Today, the electricity supply market has opened up and competition between suppliers is in full swing. Despite this, not all French consumers are aware that it is possible to change suppliers.

The study of energy mediator shows that 2/3 of French people are aware of the right to change suppliers. Moreover, we note that this proportion did not exceed 50% for more than 10 years. This is why efforts are still needed to popularize the sector. For these reasons, in this article we are going to explain to you how to simply change the electricity supplier.
Contrary to some preconceived ideas, The steps to change electricity suppliers are very simple.
Your electricity will pass through the same network, regardless of the energy supplier. Thus, regardless of the size of your structure, the terms of change will be the same on the side of the GRD (Distribution Network Manager).
All you have to do is contact the new supplier chosen and let them know that you want to take out a new contract. Obviously, a preliminary study will be necessary in order to select the offer that best suits your needs.
Once this offer has been selected, the procedures are entirely carried out by the new supplier. You don't have to do anything except sign your new contract!
You will agree on a contract start date with the new supplier. So you will receive from your former supplier a invoice which will end your previous contract.
It should also be noted that this approach is completely free. No supplier can charge you for this process.
In terms of deadlines, the change usually takes place within a few days. Consideration of your request is Instantaneous.
However, it is important to distinguish individuals from professionals on this point. Indeed, individuals can cancel their contracts cheaply (taking into account any catch-up invoices) and practically without delay.
While professionals and local authorities subscribe to contracts with a duration of commitment. It is therefore not possible for these customers to change suppliers before the end of the contract date, at the risk of paying cancellation penalties.
However, it is entirely possible to subscribe to a future contract, months before the start date of the contract, for example, to take advantage of attractive prices on the electricity markets. It is clear that today the management of a company's energy budget requires these types of risk coverage strategies.
Often one of the fears expressed by customers concerns power outages. From an electrical system perspective, whether you are with one supplier or another has no technical implications. As a result, it is therefore mainly Enedis technicians who intervene when a supplier changes.
So you just have to ask a supplier change service. Above all, you should not make the mistake of requesting the cancellation of your previous contract. This detail is important, as a cancellation can lead to the risk of an outage. The easiest way is therefore to contact only the future supplier. This service is very classic, and well known to suppliers.
In addition to the fact that this process is free of charge, it does not involve any contractual risk. Indeed, it is completely devoid of commitment if you are a private customer. You can therefore change the supplier as you wish. The simplicity of the process is the same for a company, taking into account the end date of the contract, to avoid early termination penalties.
It is entirely possible to return to the regulated rate if necessary. Once again, this approach is simple and risk-free. Does your new offer not suit you? Do not panic, you have a legal right of withdrawal of 14 days. In conclusion, we can say that this approach is free of contractual risks.
We can say that a change of electricity supplier is:
Do not hesitate to find out more about the different types of offers. There are about ten of them on the market. Surely there is a more interesting offer for you from one of the 37 providers. You now know that this approach is risk-free!
To go further, here are the 5 preconceived ideas about changing energy suppliers.

Oui, elle est considérée comme une énergie renouvelable à faibles émissions de gaz à effet de serre.
De plus, l'eau ne subit aucune transformation chimique durant le cycle de production et réintègre son milieu naturel en aval.
Cependant, la construction de barrages nécessite des mesures pour protéger les écosystèmes (débit minimum, passes à poissons).

Some businesses may obtain a partial or total exemption from the TICFE or the TICGN, depending on their activity and energy intensity. The support of an expert makes it possible to identify the eligibility criteria and to put together the file.

Instauré en 2017, ce dispositif répond à un enjeu de sécurité nationale.
L'électricité ne se stockant pas à grande échelle, le réseau doit être capable de répondre instantanément à la demande, même lors des pics de froid hivernaux. Le mécanisme incite financièrement les producteurs à maintenir leurs centrales disponibles et les entreprises à réduire leur consommation (effacement) lors de ces périodes critiques.

Among the taxes include TICFE, TICGN, CTA, CJA and TURPE. They represent a significant part of the bill and vary according to consumption profiles. Understanding them well is essential to optimize costs.

Le dispositif ARENH a laissé place au VNU (Versement Nucléaire Universel).
Ce changement structurel expose davantage les entreprises aux prix de gros, rendant la gestion des risques plus complexe qu'auparavant.
Il devient alors indispensable de définir une stratégie d'achat d'électricité avec Sirenergies pour lisser l'impact de la volatilité des marchés sur votre budget.

La Vente de Nucléaire Universelle (VNU) est le nouveau mécanisme de régulation des prix de l'électricité en France. Contrairement à l'ARENH, il ne s'agit plus d'un volume fixe à prix réduit, mais d'une redistribution financière des revenus excédentaires d'EDF aux consommateurs, basée sur les prix de marché et les coûts de production du nucléaire historique.

Absolument. La réforme des heures creuses vise à absorber la surproduction solaire en milieu de journée. Les créneaux d'heures creuses se déplacent progressivement vers la plage 11h00 – 17h00, notamment en été. C'est une opportunité majeure pour les sites industriels ou tertiaires capables de flexibilité.

La Multiannual Energy Programming (PPE) is the strategic management tool for France's energy policy. Established by the 2015 law on energy transition for green growth (LTECV), it serves as a compass for the State, communities and businesses.
Concretely, the PPE sets the priorities for action of the public authorities for the management of all forms of energy on the national territory. It covers a period of ten years, divided into two periods of five years, and must be revised periodically to adapt to technological and economic developments.
It deals with major topics such as:
It is crucial not to confuse it with National Low Carbon Strategy (SNBC). While SNBC sets carbon budgets (the ceilings for greenhouse gas emissions by sector), the PPE determines the technical and energy resources to achieve them.

La fin de l'ARENH (Accès Régulé à l'Électricité Nucléaire Historique) marque l'arrêt de la fourniture d'électricité à prix fixe garanti (42 €/MWh).
Dès le 1er janvier 2026, les entreprises sont exposées aux prix de marché, mais deux nouveaux mécanismes de régulation prennent le relais, bien que leur logique soit différente :
Conseil stratégique : Ne comptez pas sur le VNU pour réduire votre facture en 2026 si les marchés restent stables. Auditez vos contrats dès maintenant pour intégrer une part de prix fixe ou explorer des "Power Purchase Agreements" (PPA) pour sécuriser vos coûts sur le long terme.

The central objective of PPE 3 is to engage France towards carbon neutrality by 2050 by breaking the country's historical dependence on fossil fuels.
Today, approximately 60% of final energy consumption in France still relies on imported oil and natural gas. PPE 3 aims to radically reverse this trend by setting an ambitious target: to reach 60% of carbon-free energies in final consumption by 2030.
To achieve this, PPE 3 pursues three major sub-objectives:

Farms are subject to taxes such as TICFE or TICGN. Sirenergies verifies their application, identifies cases of exemption and accompanies the procedures to reduce the tax burden.

Ce seuil est jugé élevé par rapport aux prévisions actuelles du marché. Si le prix de l'électricité reste en dessous de 78 €/MWh, les entreprises ne bénéficieront d'aucune redistribution. Cela signifie que la protection promise par la réforme pourrait être inexistante dans un marché baissier, d'où l'importance de stratégies de sourcing agiles et d'outils de monitoring comme Pilott.

C'est l'indicateur d'efficacité d'un appareil électrique ; il représente le ratio entre la puissance active (utile) et la puissance apparente (totale).

Le transport (RTE) correspond aux "autoroutes" de l’électricité. Il s’agit de transporter de très grandes quantités d'énergie sur de longues distances, depuis les centrales de production (nucléaires, barrages, parcs éoliens offshore) vers les régions de consommation.
La distribution (Enedis) s'apparente aux "routes départementales" et aux rues. Elle récupère l'électricité à la sortie du réseau de transport pour la livrer directement chez le client final, en abaissant la tension pour qu'elle soit utilisable par vos appareils.

Le processus repose sur l'utilisation de la force de l'eau (énergie cinétique) issue des courants, des chutes d'eau ou des dénivelés. Le fonctionnement suit trois étapes clés :

C'est le levier le plus rapide pour obtenir des résultats visibles. L'éclairage représente environ 40 % de la consommation d'électricité d'une commune.
Passer au LED avec pilotage intelligent permet de réduire la facture de 50 à 80 %, avec un retour sur investissement (ROI) rapide, souvent estimé à 2 ou 3 ans.

Yes. The supplier guarantees an offer 100% renewable via the official Guarantees of Origin (GO) mechanism.
For the most demanding companies, the offer GREENVOLT+ ensures very low carbon intensity electricity, sourced exclusively from independent French producers (hydraulic, wind, solar).

In 2025, the supplier had a NPS (Net Promoter Score) of +16 and a note of 4,17/5.
Satisfaction is based on a “zero solicitation” model and 100% in-house customer service in Toulon, guaranteeing proximity and responsiveness that cannot be found with major historical suppliers.

Chaque modèle d'IA répond à un besoin spécifique du cycle d'achat :
L'expertise humaine reste néanmoins indispensable.

The subscribed power must be calculated according to the consumption profile and uses (heating, industrial processes, tertiary equipment). One fine analysis makes it possible to ensure the adequacy between real need and contract.
.png)
L'impact dépendra des prix de marché. Le mécanisme prévoit une redistribution si les prix dépassent 78 €/MWh. Cependant, si les cours restent bas (actuellement autour de 60 €/MWh), le dispositif ne s'activera pas. La facture sera alors indexée à 100% sur les prix de marché, rendant le choix du fournisseur et du moment d'achat critiques.

One invoice consists of several elements: consumption, supplier share, taxes and contributions. The analysis of each line makes it possible to identify possible errors and to check the consistency with the signed contract.

Exceeding capacity leads to financial penalties and can impact the size of the contract. Adjust the correctly subscribed power makes it possible to avoid these additional costs.

Tertiary companies must manage their energy costs while guaranteeing the comfort of users (offices, shops, services). Consumption is often linked to heating, air conditioning and lighting, which requires precise monitoring to avoid budgetary excesses.

Un appel d’offres permet de mettre en concurrence plusieurs fournisseurs d’électricité et de gaz afin d’obtenir des conditions contractuelles optimisées. C’est une démarche transparente qui permet de choisir l’offre la plus adaptée aux besoins budgétaires et techniques de l’organisation.

Le prix Forward est fixé à l'avance (sécurité budgétaire), tandis que le prix Spot varie heure par heure selon le marché (opportunité mais risque élevé).

L'abondance de production française tire les prix du marché de gros vers le bas.
En vertu du mécanisme de l'Ordre de Mérite (Merit Order), les centrales les moins coûteuses (nucléaire, renouvelables) couvrent la demande plus souvent, évinçant les centrales à gaz ou charbon plus onéreuses.
Cela multiplie les épisodes de prix bas, voire négatifs, sur le marché spot.

Absolument pas. Le courant continue de passer par les mêmes câbles gérés par le gestionnaire de réseau (Enedis). Seule la facturation change de main.
