The weight of the electricity bill weighs heavily on the budgets of businesses and local authorities. There are concrete and effective solutions to control your energy expenses. Several levers are available to you to make immediate savings, while making sustainable choices for the future. Discover six effective strategies that will help you optimize your energy budget and inform your decisions.
Check your subscribed power
The subscribed power is the power that the electric meter can call up to cover the simultaneous consumption of electricity at a given moment. Choosing the right subscribed power avoid unpleasant surprises on the electricity bill.
The financial consequences of a poor estimate of the subscribed power
The choice of subscribed power has a direct impact on the delivery rate (TURPE), and therefore on the cost of the subscription. An incorrect estimate incurs additional costs:
- An underestimate of the subscribed power may generate power overruns, sanctioned by financial penalties. They can reach around ten euros per hour exceeded.
- An overestimate of the purchased power unnecessarily increases the cost of the monthly subscription.
Can the subscribed power be modified?
The subscribed power is indicated on your electricity bill or in your customer area. You can change at any time during the term of your contract. The request is sent to the electricity network operator via your energy supplier. Bad news for your budget: Enedis or your Local Distribution Company (ELD) Charge for the power change.
Before opting for a modification, clever calculations are required. If you rarely exceed your power threshold, paying the occasional penalties may be more economical than increasing your subscription.
Carry out energy renovation work
Along with energy efficiency and renewable energies, energy renovation is one of the three levers of the energy transition. In addition to reducing greenhouse gas emissions, energy renovation is decreasing energy consumption and reduces the electricity bill.
How does energy renovation reduce the electricity bill?
The thermal insulation of buildings, the replacement of carpentry and energy-consuming equipment or the installation of heating systems and airconditioning efficient ones all have one thing in common: they reduce energy consumption. The evidence is there: The less kWh you consume, the less you pay for electricity. This also makes it possible to reduce the power purchased, and therefore the cost of the subscription.
Energy renovation is synonymous withshort-term financial savings. It also improves the working comfort of employees, as well as thecarbon footprint of your business or community.
Optimizing investments in energy renovation
Although energy renovation generates immediate and long-term savings on the electricity bill, its initial cost can be a hindrance.
Numerous financial aids exist to reduce investment. ADEME offers professionals a broad program of subsidies. Businesses and local authorities can also benefit from Energy Saving Certificates (CEE), fiscal aid or adapted loans (Energy Savings Loan — PEE).
One prior energy audit is essential for identifying the most profitable energy solutions and optimizing the investment.
Switch to self-consumption
Individual or collective, self-consumption consists in producing and consuming one's own local and renewable electricity, most often via solar panels. This sustainable choice makes it possible to make substantial savings.
How does self-consumption reduce the electricity bill?
On average, self-consumption reduces the electricity bill by 20 to 40%. By consuming your own electricity, You are in fact reducing the volumes of energy purchased on the network. Even if your consumption remains the same, your electricity bill decreases.
Self-consumption has other advantages: it reduces energy dependence to the network and secure supplies. By limiting electricity purchases, it also protects against price fluctuations on energy markets.
Is self-consumption always a profitable choice?
Self-consumption is always profitable in the long term, provided that you have properly sized your photovoltaic installation. A technical and financial feasibility study helps to make the right choices and optimize the self-consumption rate. The higher it is, the lower the quantity of electricity purchased and the lower the electricity bill.
La Self-consumption bonus And the attractive purchase price in case of partial resale help to control the investment. Depending on its production, the self-producer can also claim a reduction or exemption from excise duties on self-consumed electricity.
Adopting energy sobriety
Energy sobriety is based on the adoption of simple actions that are accessible to everyone to reduce electricity consumption. Free of charge, these actions generate quick and immediate financial savings.
What actions should be taken to reduce electricity consumption?
- Opt for LED bulbs low consumption and favor natural light.
- Switch off electrical appliances at the end of the day and set the sleep function. A computer that is on all the time can cost up to 100 euros per year!
- Optimizing the use of equipment by adapting their dimensions to real needs and by limiting, for example, the number of printers and audiovisual systems.
- Reduce heating and cooling : one degree lower in temperature has an impact on consumption by 7% per year.
How to encourage energy sobriety?
Energy efficiency is based on the goodwill of all employees. La Communication plays a key role to raise awareness and mobilize around good practices. She participated in the creation of a shared corporate culture around shared and responsible values. Environmental and energy exemplarity strengthens cohesion, reduces turnover and attracts new talent.
Buying electricity wisely
The amount of your electricity bill does not only depend on the volume of your consumption. It also depends on your buying strategy. The challenge: to buy electricity from right time and at the best price.
Define an effective electricity purchasing strategy
Buying at a fixed price or at a variable price, long-term forward product or short-term spot product, buying in installments or buying in blocks, pricing options...: there are multiple purchasing strategies.
To optimize your electricity expenses, choosing the right strategy is crucial. To do this, you must absolutely understand your consumption profile and master the dynamics of the electricity market.

.png){kind=icon}
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 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.
Qu'est-ce qui remplace l'ARENH en 2026 pour les entreprises ?
L'ARENH est remplacé par le VNU (Versement Nucléaire Universel), un mécanisme de redistribution des revenus excédentaires d'EDF en cas de prix très élevés, et par les CAPN, des contrats long terme pour les gros industriels.
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.
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.
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 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.
Comment réduire la puissance souscrite de son compteur ?
En analysant votre courbe de charge pour identifier la puissance réelle appelée, puis en demandant un ajustement à votre fournisseur ou via un expert en énergie.
How to optimize taxes and contributions?
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.
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.
Who can benefit from optimizing invoices and taxes?
All businesses, from SMEs to large organizations, can benefit from this service. Les local authorities also find it a lever to better control their budgets.
Quelles sont les nouvelles obligations pour le Décret Tertiaire et l'Audit Énergétique ?
Le calendrier 2026 impose deux échéances majeures :
- la déclaration des consommations 2025 sur la plateforme OPERAT avant le 30 septembre
- la réalisation d'un audit énergétique avant le 11 octobre pour toutes les entreprises consommant plus de 2,75 GWh/an.
Pour simplifier ces démarches, vous pouvez centraliser vos données de consommation avec la plateforme Pilott de Sirenergies, garantissant ainsi la conformité de vos rapports réglementaires.
What are the energy challenges for manufacturers?
Industrial companies consume large volumes of energy for their production processes. They have to deal with the volatility of prizes, multi-site management and specific taxes. Controlling costs is essential to remain competitive.
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.
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 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.
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.
Le prix de l'électricité va-t-il baisser en 2026 ?
Pas nécessairement sur votre facture finale. Si les prix de gros (le prix de l'énergie brute) ont baissé, les coûts d'acheminement (TURPE) et certaines taxes augmentent, compensant souvent la baisse de la part énergie.
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.
Comment réduire ma facture si les prix du marché sont volatils ?
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).
Pourquoi l'humain est-il le premier levier de la performance énergétique ?
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.
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.
What are the energy challenges of the agricultural sector?
Farms must deal with high seasonal needs (greenhouse heating, irrigation, storage) and high volatility of prizes. Controlling these costs is essential to maintain profitability and secure the business.
Quand faut-il renégocier son contrat d'électricité professionnel pour 2026 ?
Idéalement entre 6 et 12 mois avant l'échéance, de préférence au printemps ou au début de l'été lorsque la demande est plus faible.
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.
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.
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.
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).
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.
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.
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).

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).
Comment mobiliser les collaborateurs autour d'un projet de sobriété énergétique ?
La réussite d'un projet collectif énergie repose sur trois piliers fondamentaux :
- La visibilité : On ne gère bien que ce que l'on mesure. Partager les données de consommation via des outils comme l'application Pilott donne un sens concret aux efforts fournis.
- L'incarnation : Nommer des ambassadeurs énergie internes permet de diffuser les bonnes pratiques par l'exemple et de lever les freins opérationnels propres à chaque métier.
- La gamification : Transformer la contrainte en défi (challenges inter-services, concours de l'équipe la plus sobre) crée une dynamique positive et renforce la cohésion d'équipe autour des enjeux RSE.
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.
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 change energy suppliers?
Changing suppliers can allow you to benefit from more competitive prices, adapted services or better contractual conditions. Thanks to sourcing, change is happening without interruption of supply.
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.
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).
Comment financer les travaux communaux sans augmenter la taxe foncière ?
Plusieurs leviers existent pour préserver la fiscalité locale :
- Les CEE (Certificats d’Économie d’Énergie) : Un financement privé majeur pour l'efficacité énergétique.
- L'optimisation de l'achat d'énergie : Choisir des contrats adaptés (prix fixes, indexés ou groupés) pour dégager des marges de manœuvre dès la première année.
- Les aides publiques : Mobiliser le Fonds Vert, le FEDER ou le Fonds Chaleur.
What are the concrete benefits for tertiary companies?
Les profits include a direct reduction in bills, strengthened budgetary forecasting and better control of consumption. Businesses gain visibility and efficiency thanks to adapted tools.
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.
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.
What are the advantages of sourcing?
Sourcing offers better visibility on the market and promotes the selection of competitive contracts. It helps to reduce the risks associated with price volatility and to optimize the energy budget.
