You may have had the unpleasant surprise of seeing a line on your bill concerning power overruns. Indeed, it appears on your bill if you do not optimize the power of these sites. This can happen at different types of sites and may concern large areas, as well as industrial sites.
Generally, these additional costs often go unnoticed, as energy costs are often incurred. However, the good news is that it is possible to change the strength of your contract.
By getting support, it is possible to optimize your network rates. It should actually be remembered that this only concerns TURP. That's about a third of your electricity bills. It is therefore a question of a major cost item.
First, it should be remembered that the TURPE set by the public authorities is the network rate for the transport of electricity. This rate is paid by all electricity consumers. It pays network operators for their services, namely the transport and delivery of electricity. The main principles of this tariff are: the postage stamp and tariff equalisation.
However, this rate also covers a number of network costs. Les power overruns are covered by this device. Indeed, it compensates Enedis and RTE for the management of the consequences of these power surges.
Generally, when opening an electricity contract for a company, the customer must choose a subscribed power as well as a version for use.
Moreover, the power subscribed is a central reference in a contract. Indeed, this value determines the theoretical maximum power that can be called. Overall, this is one of the key elements of the contract.
Then, if all of your installations (machines, lighting, etc.) draw more power from the network than this threshold, you exceed your power. Professional electric meters allow this. In general, professional sites have several different powers depending on the time range.
These powers are arranged in ascending order (from peak to HCE). Indeed, this makes it possible to reduce the largest power calls over the least demanding hours for the network.
To avoid power surges, it is therefore necessary to avoid extracting more than this value over the corresponding periods of time.
To help you see it a bit more clearly, here is the correspondence table with an example:
Some businesses choose Differentiated powers depending on the time period. For example, there are industries that only work in summer. It is therefore more interesting not to pay too much power over the rest of the year. We are starting to feel here that it is possible to optimize this part of your final bill.
There is a second option to subscribe to open a new electricity contract. It's about the version of use. There are several, depending on the size of your site.
You can then subscribe to a long, medium or short use. In TURPE, there is a variable part that depends on the intake as well as a fixed portion that depends on the power of the customer. Depending on your choice, you will pay a variable, important rate, but a low fixed part, or the other way around.
Perhaps you are asking yourself what is the point of this choice? It all depends on how you consume. If you consume continuously or prefer certain moments (only during the day, during the week with a stop at the weekend...).
Now that you have in hand all the elements to understand a TURPE optimization, we will explain the method to you.
It is essential to contact a competent service provider in order to carry out this calculation for you. The aim is to offer you new powers and a new FTA to subscribe to.
In order to find the most suitable combination, the algorithm used will test all possible cases and offer you the subscription that best suits your situation.
This makes it possible to avoid overruns of the subscribed power.
It should not be forgotten that an optimization of TURPE is based on a history of consumption, and therefore on past behavior. In any case, if you change the way you consume (significantly), the old optimization will no longer be current.
There are also sites whose power is already optimized. If you have never carried out this type of operation, we invite you to contact us or to make an appointment with one of our energy experts.
The optimization of TURPE therefore takes place a posteriori. We note the consumption made over the year and we offer a subscription for the following year. We thus assume that behavior will not change too much over the next year.
However, it is possible to subscribe to services that allow you to know all of your consumption. in real time. So you can identify your most energy-consuming devices and prevent an unexpected increase in electrical demand.

Your service provider will install many sensors on your devices, generally you will have software capable of displaying this data in real time.
This may even concern individual customers with the details of the consumption of their household appliances. This approach is part of the implementation of an Energy Management Strategy (SME).
The installation of smart electric meters such as Linky can also have a beneficial effect. It allows you to obtain your consumption as close as possible to reality.
To go further, do not hesitate to consult our guide to Understand your business electricity bill.
One overrun of subscribed power occurs when the power requested from the network is greater than the power subscribed to.
In an individual, the meter goes out immediately when it is exceeded. For a company (excluding C5), the meter does not break. Imagine if a worker was under a 27-ton electromagnetic press at that moment...
SirEnergies helps you optimizing, to visualize and to change the power subscribed to your meter using Enedis and your supplier. Optimizing these network rates represents an opportunity to reducing your electricity bill and prevents you from paying unnecessary financial penalties.

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.

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.

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).

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.

En 2026, les principaux leviers sont : la renégociation de votre contrat de fourniture au bon moment, l'optimisation de votre tarif d'acheminement (TURPE), la vérification de votre éligibilité aux taux réduits de taxes (Accise), et la réduction de votre consommation (efficacité énergétique, autoconsommation).

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.
.png)
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.

Même le bâtiment le plus moderne et le mieux isolé perd son efficacité si ses usages sont inadaptés. La technologie et les normes ne suffisent pas : la transition énergétique est avant tout une transformation humaine.
Derrière chaque kilowattheure consommé se cache une habitude.
Un collaborateur sensibilisé comprend qu'ouvrir une fenêtre alors que le chauffage est allumé ou laisser un ordinateur en veille consomme de l'énergie inutilement. En replaçant l'humain au centre de la stratégie de gestion de l'énergie, l'entreprise s'assure que ses équipements performants sont utilisés de manière optimale, garantissant ainsi une rentabilité durable et un impact environnemental réduit.

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.
