An indispensable commodity for decades, electricity is widely used by businesses. As a result, the cost of energy consumption by these latter is most often considerable.
You're probably constantly looking for ways to make less expenses than revenue. Reducing the electricity consumption of your structure marks a clear path for you to get there. In addition, it will be your contribution to reducing the impact of the energy sector on the climate.
SirEnergies reveals you here 5 solutions to achieve energy savings within your company.
Perform an energy performance diagnosis
Before taking action to reduce your business's electricity consumption, you need to know exactly what you need to fix. So start by submitting your building to an energy performance diagnosis (DPE) if it has been done a long time ago. This operation is used to assess a building's energy consumption and the resulting greenhouse gas emissions.
The DPE has become mandatory since the 1Er July 2021 in certain situations such as renting. This shows how important it is from the point of view of public authorities to achieve the energy transition.
The DPE will allow you to identify the levels at which you must act to reduce the quantity of electricity consumed by your business premises. It can be read through the energy label, which indicates the consumption of primary energy, and the climate label, which indicates the volume of greenhouse gases emitted.
Each label includes 7 classes ranging from A to G, i.e. from the best to the worst performance. The DPE must be carried out by a diagnosticist approved by the COFRAC (French Accreditation Committee). The DPE is accompanied by recommendations that guide the sponsor towards energy efficiency actions. Depending on the results of the diagnosis, the professional may recommend, for example, thermal insulation work.
Strengthen the thermal insulation of the building
To save energy in your business, consider thermal insulation. Over time, any building becomes more permeable to temperature transfers between inside and outside. Reinforcing the insulation of your building may be necessary. You can do it through some work.
Wall insulation from the outside
Insulation from the outside is one of the methods for removing thermal bridges in a building. It consists in putting insulating material on the exterior walls. The related work does not prevent the use of the premises. Wall insulation from the outside can be done with insulating materials made of wood fibers, hemp or flax, polystyrene, vegetable or mineral wool, etc.
Wall insulation from the inside
Wall insulation from the inside is recommended to prevent energy losses in the building without changing its external appearance. It does not require major work. However, the staff will not be able to work peacefully on the premises during the operation. Like the external insulation technique, this can allow you to avoid up to 25% heat loss, according to ADEME (Agency for the Environment and Energy Management).
Other insulation work, such as insulation, can help you reduce your energy consumption.
Optimize heating to save money
The heating system consumes a lot of energy in any building. Consider improving it to make it as energy-efficient as possible. If your premises have a boiler that is at least two decades old, the ideal would be to replace it with a recent model designed to promote energy efficiency.
We recommend a low temperature or condensing heating system. You also have the possibility to change the source of energy to heat your premises. You can thus opt for a large capacity wood pellet boiler, which can supply the entire building.
Opt for low-consumption light bulbs and appliances
The lighting and the various devices used in your professional building occupy a significant part of its energy consumption. Incandescent lamps no longer belong anywhere. Replace them with LED lights which are low-consumption light bulbs that save watts of electricity.
The air conditioner lowers the temperature in a building, but in most cases it causes the energy bill to skyrocket. To save money, it may be useful to replace your air conditioning system with another high performance device. The same goes for other electrical equipment such as the refrigerator.
Enact simple energy-saving actions
To make your company a structure committed to energy efficiency, you need to get staff to share your vision. Employees have a role to play in this sense, especially since they are the ones who use the installations and equipment for the most part. Please make them aware of the need to reduce energy consumption of the company.
Remind them of simple actions to achieve this goal. For example, ask them to turn off the lights when leaving their offices, to use daylight if possible, to turn off the devices when they get home, etc.

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.
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.
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.
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).
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.
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.
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.
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 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.
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.
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.
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 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.
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 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.
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.
Why is Scope 2 crucial for CSR?
It allows you to prove your commitment to the energy transition and to meet regulatory requirements.
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.
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.
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.
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 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.
How do you calculate Scope 2 emissions?
To calculate Scope 2 emissions, use the following formula:
Energy quantity (kWh) × Emission factor (kg CO₂ e/kWh).
Use databases like ADEME for precision.
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 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 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.
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.
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.
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).
