With a price per MWh that is “times two (x2) or even times five (x5)” in the operating budgets of companies, the question of energy mix in energy purchases for businesses is increasingly becoming a necessary and sustainable solution.
We already detailed in a previous article The mechanisms of Arenh which entitles, if eligible, to a portion of its energy at €42 per MWh. We are going to address the issue of self-consumption using photovoltaic solutions installed on company sites.
Today, self-consumption is an effective way to meet the energy needs of your company, local authority or association, by getting involved in an ecological transition process.
How does self-consumption work? Why switch to self-consumption as professionals? What are the costs for self-consumption? An expert in energy transition issues, SirEnergies tells you about the ins and outs of self-consumption for professionals.
How does self-consumption work?
THEself-consumption concerns the installation and commissioning of personal energy production systems (in particular solar energy) in order to meet the needs of the organization. The aim here is to get as close as possible to energy independence.
Definition of self-consumption
It consists in producing electricity using photovoltaic panels for consumption on site. Thanks to the sun's rays, thesolar photovoltaic installation produces direct electrical current that will later be transformed into alternating current. The photovoltaic installation can be carried out on the roof or on the ground.
Self-consumption can be total. In this case, all the electrical energy produced is consumed in the premises. Your buildings remain connected to the public electrical network, which takes over automatically when the system finds that the self-consumption rate is equal to 100%.
It may happen that the electrical power produced by your photovoltaic installation exceeds your consumption needs. So you haveA share of excess production that you can sell to an operator. You sell the surplus at a purchase rate higher than the price per kWh on the public electricity network. It is said that you practice self-consumption with the resale of surplus.
The importance of properly sizing a self-consumption installation
The photovoltaic installation must be carried out by an RGE professional (Recognized Environmental Guarantor) competent, who can adapt the number and power of solar panels to the energy resources you need.
Choosing a serious and experienced professional for your investment in solar energy allows you to benefit from a sustainable and efficient installation. Depending on the targeted mode of self-consumption (partial or total), you can thus size your system to take advantage of energy production at a cost that is more competitive than current market prices.
The objective is to best synchronize the time of consumption with that of electricity production to obtain an ideal self-consumption rate per day. To size the photovoltaic installation in self-consumption, several criteria must be taken into account:
- The daily consumption profile;
- The areas available to carry out the solar installation;
- The rate of sunshine in the region and the seasonal characteristics of the region;
- Shadow areas concerning the potential installation and orientation of the PV panels.
Why switch to self-consumption as a professional?
Producing electrical energy through a photovoltaic installation will allow you to reduce your energy bill while contributing to your obligations related to Tertiary decree (1)re due in September 2022).
It is an excellent way to affirm your organization's unwavering involvement in the CSR (corporate social responsibility) approach, which improves its image among the public. SirEnergies is at your disposal to help with adopt solar self-consumption effectively and quickly in your company or association.
Photovoltaic consumption: producing your own electricity
Producing your own electricity by investing in photovoltaic panels is an excellent solution to deal with rising electricity prices.
If we also consider that the cost of photovoltaic installations has fallen significantly in recent years, it is an economical way to benefit from a 100% green energy.
By strengthening your total or partial autonomy in need of electricity, you significantly reduce the budget devoted to the use of electrical energy.
In addition, by selling the portion of excess electricity production, under an obligation to purchase to EDF, you can generate additional income.
Store your solar production to consume your electricity
Storage batteries can be associated with your solar installation in order to be able to use your electrical devices even when the sun's rays are non-existent. Thus, the role of these batteries will be to store excess electricity if the option of reselling to the network does not suit you.
Choosing adapted and efficient photovoltaic panels will help you benefit from photovoltaic energy for 25 to 30 years, provided you maintain your installations properly (loss of efficiency of 0.5% per year for solar panels, which implies that after 20 years, the system will still operate at 80% of its capacity).
Solar self-consumption is a sustainable project with many advantages for professionals and businesses.
What are the costs for self-consumption?
Consuming your own electricity production requires a significant investment in view of significant energy needs of professionals. To encourage the eco-responsible initiative of companies or associations, however, the government has taken certain measures such as Energy Saving Certificates (CEE).
In addition, some companies can assist you in the study, optimization and financing of your installations. SirEnergies can help you find the right partner and optimally integrate this production into your energy purchasing and consumption strategy.
At what rate is the electricity produced purchased?
Thanks to contracts under obligation to purchase, EDF or any other electricity supplier can buy excess electricity from your installation. The rates are fixed by the CRE (Energy Regulatory Commission) and contracts under obligation to purchase are valid for 20 years.
By consuming yourself, you can thus improve your financial resources by reselling your excess energy.
What is the installation cost?
The cost of installing photovoltaic panels on a professional site depends on several factors. These include the overall power of the installation, the technique for installing the panels, the manufacturer of the accessories or the quality of the solar panel (monocrystalline or polycrystalline). The presence of virtual or physical batteries, the presence of an intelligent system for managing the photovoltaic installation, the cost of labor will also influence the cost of your project.
What are the solutions to finance your self-consumption project?
As a professional, you can benefit from The self-consumption premium.
Self-consumption is a CSR approach that consists in consuming the electricity produced by your own photovoltaic installations. It offers the possibility of reduce the energy bill of your organization and to make additional income in the event of reselling excess electricity to a supplier.
You can also store solar electric power to use when it's dark. Various State aids make it possible to finance your projects in this area: sales with the obligation to buy, the self-consumption premium, the reduction of VAT... Call on the expertise of SirEnergies to facilitate the implementation of your professional self-consumption project, just about everywhere in France.

The answers to your questions
Quelles sont les nouvelles obligations pour le Décret Tertiaire et l'Audit Énergétique ?
.png){kind=icon}
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.
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.
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).
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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).
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).
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.
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
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.
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.
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).
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.
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 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.
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.
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.
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.
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.
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.
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.
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.
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 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 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.
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.
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.
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.
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.
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.
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.
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).
