Since 2015, the deployment of the Linky electricity meter has been a solution that intervenes as part of the energy transition. This meter allows Enedis (the network manager) to monitor users' consumption in real time and to manage a safe electrical network. It also allows users to have control of their consumption.
However, the Linky meter is the subject of numerous criticisms from consumers and consumer associations. Between the Enedis experts who reassure and the anti-Linky who point out the risks of this meter for health, household and housing, it is easy to get lost. At the end of the day, Is the Linky meter dangerous or not?
Linky smart meters: a health hazard?
According to some users of the Linky meter, the waves emitted by this meter would be dangerous for the health of people in the vicinity. In practice, it would cause cancers, discomforts and diseases of all kinds, especially in electrosensitive people. What is the situation really?
The Linky meter does not use wireless technology and does not work like a cell phone. Instead, he uses Online Carrier Current technology (PLC) to pass data through the electrical cable. It is this passage of data in the electrical cable that generates electromagnetic waves.
However, the waves generated do not go beyond the cable area. This is a fact confirmed by the National Frequency Agency (ANFR). As for the waves emitted by the electronic board of the energized device, they are no larger than those emitted by a refrigerator. It appears that the emission of waves by the Linky meter does not represent a danger to the health of users.
Linky smart meters: a fire risk?
It is true that fires started in 2010 after the old traditional meters were replaced by the new Linky meters. To be precise, 8 cases of fires were counted among the 300,000 meters installed between 2010 and 2015.
Since then, the anti-Linky people have not missed any opportunity to decry the fact that there is a real risk of fire using the Linky meter. As for Enedis manager, he formally maintains that the intrinsic characteristics of the Linky meter did not cause the accidents mentioned above.
The fires could be attributed to mechanical tightening (a technical gesture) that was not sufficiently carried out by the installers. The training of professionals who install the smart meter has been strengthened so that, since 2015, fire cases have remained very rare.
The use of the device would now reduce The risk of fire because the technicians who come to install the meter carefully check the status of the connection. Laboratory tests and post-fire investigations come together: Linky meters do not present a fire risk, or at least no more so than electromechanical and electronic meters.
The Linky meter: a spy in the household?
The Linky meter collects a significant amount of personal household information. This is of great concern to the anti-Linky. In reality, the Linky meter can know the electricity consumption of each device in a home at any time. Businesses can analyze this personal data to find out the habits of Linky meter users:
- The time of sunrise and sunset for French people;
- The periods of absence;
- The number of people in a house...
Enedis experts reassure users about respect for privacy and confidentiality of the data collected. The manager has put in place protections for consumers' personal data in accordance with the recommendations of the CNIL (Commission Nationale de l'Informatique et des Libertés).
Enedis thus finds rational answers to all the concerns raised by the anti-Linky. If it were possible to refuse the installation of Linky meters, everyone could assert their right. The installation of these meters takes place within a legal and mandatory framework. The best thing to do would therefore be to carefully analyze the advantages of the device in order to take maximum advantage of it.

.png){kind=icon}
Tertiary companies are concerned by taxes such as TICFE or TICGN. Sirenergies checks the accuracy of invoices, identifies possible exemptions, and helps correct errors to sustainably reduce costs.
What are the main taxes applicable?
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.
What are the challenges for tertiary companies?
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.
Qu'est-ce qui remplace l'ARENH depuis le 1er janvier 2026 ?
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.
How to properly define your subscribed power?
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.
Quel est le nouveau record 2025 d'exportation d'électricité de la France ?
En 2025, la France a atteint un solde exportateur net de 92,3 TWh, battant le précédent record de 2024 (89 TWh).
What is the difference between €/MWh and kWh?
The €/MWh is a price unit used in wholesale markets, while kWh is the unit visible on your bills.
How to optimize the taxes and contributions of a community?
Communities are subject to taxes such as TICFE or TICGN. Sirenergies analyzes invoices, identifies exemption possibilities and fixes possible errors to reduce the tax burden.
What are the electricity offers offered by bellenergie Business?
The range E @sy is available in four pricing structures to adapt to each risk profile:
- E @sy Fixed: 100% budget visibility without variation.
- E @sy Click: Smoothed price thanks to staggered purchases on the markets.
- E @sy Block + Spot: A mix between a secure base and a portion indexed to daily prices.
- E @sy Sport: A 100% dynamic offer to take advantage of downside opportunities in real time.
What is energy sourcing?
Sourcing consists in identifying and analysing the offers of several electricity and gas suppliers. This approach makes it possible to obtain contracts adapted to the consumption profile and budgetary constraints of the company.
What taxes are particularly relevant to manufacturers?
The industry is concerned by TICFE, TICGN and other contributions that may represent an important part of invoices. Sirenergies identifies cases of exemption and accompanies the procedures to benefit from them.
Quel est l'impact réel de la rénovation de l'éclairage public ?
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.
What are the consequences of overpowering?
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.
Quel est l'impact de ces exportations sur le prix de l'électricité pour les entreprises ?
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.
Is Bellenergie Business electricity really green?
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).
L'hydroélectricité est-elle une énergie "propre" ?
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).
What is the point of following Spot & Forward prices?
This makes it possible to choose the right time to contract, secure your budgets and anticipate increases.
Pourquoi la France a-t-elle exporté un volume record d'électricité en 2025 ?
Ce record de 92,3 TWh s'explique par la conjonction de trois facteurs :
- Le redressement du parc nucléaire : Après les problèmes de corrosion sous contrainte de 2022, la production nucléaire a retrouvé une forte disponibilité (373 TWh).
- L'essor des renouvelables : Une capacité installée en hausse (solaire et éolien) et une production hydraulique solide.
- Une consommation intérieure atone : La demande française reste inférieure de 6 % à la moyenne historique, créant un surplus massif disponible pour nos voisins.
Quelle est la différence concrète entre le transport et la distribution d'électricité ?
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.
How do I get a tax exemption?
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.
Pourquoi le kVA est-il crucial pour les entreprises ?
Parce que la puissance souscrite en kVA détermine le prix de l'abonnement et que tout dépassement peut entraîner des surcoûts importants.
Qu'est-ce que le cosinus phi
C'est l'indicateur d'efficacité d'un appareil électrique ; il représente le ratio entre la puissance active (utile) et la puissance apparente (totale).
What are the customer reviews on bellenergie Business's customer service?
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.
Comment l'eau est-elle transformée en électricité ?
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 :
- Le barrage retient l'eau et l'oriente vers des conduites.
- La pression de l'eau fait tourner une turbine, créant de l'énergie mécanique.
- Une génératrice (alternateur) transforme cette énergie mécanique en électricité, laquelle est ensuite adaptée par un transformateur pour le réseau
Why launch an energy tender?
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.
Which taxes are particularly relevant for farms?
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.
How do I read an electricity or gas bill?
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.
Pourquoi mon contrat est-il en kVA et ma consommation en kWh ?
Le kVA mesure la capacité maximale que votre compteur peut supporter à un instant T, tandis que le kWh mesure la quantité d'énergie consommée sur une durée.
What are the PP1 and PP2 alert days?
These are signals sent by RTE during periods of tension on the electrical network. The Sirenergies tool informs you in real time to anticipate your uses.
