Until the 2000s, monopolies and regulated sales tariffs governed the supply of electricity and gas in France. Under the impetus of Europe, energy markets have been opened up to competition. Businesses and local authorities must subscribe to a market offer.
But comparing the offers of energy suppliers is difficult. The number of players, the diversity of offers, price volatility and regulations complicate the task.
How can you buy your energy well in this unstable and complex context? How to manage risks to your company's budget?
Our courses of action.
The electricity and gas markets are governed by the law of supply and demand. The slightest regulatory, political or economic hazard changes the equation, resulting in reduced visibility on prices and contracts.
The opening at the Competition in the electricity and gas markets has seen numerous players appear on the market, seduced by this new opportunity. In 2024, businesses have the choice between a thirty historical and alternative suppliers for electricity and a dozen for gas.
Each supplier has its own specificity. Between traditional electricity and/or gas suppliers, green energy suppliers, suppliers producing renewable energies, local suppliers, suppliers with citizen governance, suppliers from France and Europe, companies are facing a difficult choice for reconciling budgetary control and environmental and social commitment.
In 2024, regulated electricity tariffs remain only for individuals and businesses with fewer than 10 employees and with a turnover of less than 2 million euros. For their part, regulated gas sales rates have completely disappeared.
These rates are replaced by market offers. This is where your brain heats up in the face of the diversity of contracts. Market mechanisms have opened the way for the development of numerous offers, whether they are fixed prices indexed to the forward market, at fixed prices that can be adjusted, at variable prices indexed to the spot market, mixed or even green.
If energy markets are liberalized, Europe and states intervene to regulate prices, protect consumers and secure supplies.
Thus, since 2017 in France, the capacity mechanism has complicated energy purchases. It forces suppliers to buy capacity guarantees. As their name suggests, they guarantee their ability to supply electricity to all their customers during peak consumption.
A recent reform could also upset the European electricity market: the European directive 2024/1777. Entered into force on July 16, 2024, it aims to control electricity prices in times of crisis, to stabilize markets in the long term and to accelerate the deployment of renewable energies. The text encourages the development of long-term power purchase contracts, at a rate set at the time of subscription to prevent price volatility.
Fighting climate change is a necessity. The energy transition concerns all areas, especially energy purchases.
Businesses are encouraged to subscribe to low-carbon green deals to reduce their greenhouse gas emissions and improve the Scope 2 of their carbon balance. They are also encouraged to include in their energy purchases environmental, social and governance (ESG) criteria, scrutinized by potential investors, partners and other stakeholders to assess the extra-financial performance of companies.
Subject to the laws of the market, energy prices change every day, with a short-term visibility.
As the last few years have shown, energy markets are responding to geopolitical and economic turmoil. The war in Ukraine has caused the price of electricity and gas to soar. Galloping inflation has had an impact on energy prices. Without the aid granted by the State to professionals, prices would have increased by 74% between 2021 and 2024.
Temperatures also affect electricity demand. Or any imbalance between supply and demand results in a rise or fall in prices.
Do air conditioners run at full speed during a heatwave? These peaks in electricity consumption lead to higher prices on the market in the face of insufficient supply. On the contrary, is winter mild and electricity consumption lower than expected? As supply exceeds demand, prices are falling.
The complexity and instability of the electricity and gas markets are not without consequences for businesses. Bills can fluctuate as prices change, unbalancing budgets. Financial risks can be controlled with an adapted purchasing strategy.
Limiting energy purchases is the most pragmatic solution to control the associated risks. To reduce dependence on electricity and gas, businesses can produce and consume their own renewable and local energies. Many technologies are being developed today to diversify energy sources, such as photovoltaics, The wood, the biomass or even the geothermal energy.
Another course of action: the basic reduction of energy needs, by adopting energy-saving measures, by insulating buildings or by replacing the most energy-consuming equipment.
Know, understand and anticipate. These are the golden rules for buying energy well and optimizing contracts.
Buying at a fixed and firm price, buying at a variable spot price, buying in installments, buying in blocks...: buying strategies are variable. Every business must Define the strategy best suited to your consumption profile, its budget and its solidity in the face of financial risk.
Securing energy purchases requires a detailed knowledge of energy consumption depending on the periods. But that is not enough. To buy well, you must be able to follow, understand and anticipate the evolution of electricity and gas prices.
Tools help businesses set up monitoring and proactive management of their purchases and their contracts. Through its dedicated application, the energy consulting firm SirEnergies offers a detailed monitoring of consumption daily, weekly and monthly. The platform also gives access to daily price changes, complemented by a weekly market analysis.
Equipped with these elements, businesses can identify the Best time to buy or renegotiate their contracts.
In an uncertain context, deciphering energy markets and managing purchases is complex. Many large companies now have a specialized buyer or train their teams internally.
It is also possible to use external energy consulting firms.
At Sirenergies, our experts:
- Help you navigate the diversity of offerings and the complexity of energy markets.
- Continuously analyze price trends to identify the best opportunities for your needs.
- Support you throughout the life of your contracts electricity and gas to control your bills, (re) negotiate offers, optimize rates and control your energy consumption.
In recent years, energy purchases have continued to become more complex, under the effect of market liberalization, regulatory changes, energy transition obligations, and economic and political upheavals. Securing energy purchases requires specialized and varied legal, financial and commercial skills. It also requires expert knowledge of the electricity and gas markets, supplemented by constant monitoring as these markets are complex and volatile. The energy consulting and sourcing firm SirEnergies offers companies, professionals and local authorities tailor-made support to reduce the risks associated with energy purchases.

La fin de l'ARENH (Accès Régulé à l'Électricité Nucléaire Historique) marque l'arrêt de la fourniture d'électricité à prix fixe garanti (42 €/MWh).
Dès le 1er janvier 2026, les entreprises sont exposées aux prix de marché, mais deux nouveaux mécanismes de régulation prennent le relais, bien que leur logique soit différente :
Conseil stratégique : Ne comptez pas sur le VNU pour réduire votre facture en 2026 si les marchés restent stables. Auditez vos contrats dès maintenant pour intégrer une part de prix fixe ou explorer des "Power Purchase Agreements" (PPA) pour sécuriser vos coûts sur le long terme.

La Multiannual Energy Programming (PPE) is the strategic management tool for France's energy policy. Established by the 2015 law on energy transition for green growth (LTECV), it serves as a compass for the State, communities and businesses.
Concretely, the PPE sets the priorities for action of the public authorities for the management of all forms of energy on the national territory. It covers a period of ten years, divided into two periods of five years, and must be revised periodically to adapt to technological and economic developments.
It deals with major topics such as:
It is crucial not to confuse it with National Low Carbon Strategy (SNBC). While SNBC sets carbon budgets (the ceilings for greenhouse gas emissions by sector), the PPE determines the technical and energy resources to achieve them.

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.

Instauré en 2017, ce dispositif répond à un enjeu de sécurité nationale.
L'électricité ne se stockant pas à grande échelle, le réseau doit être capable de répondre instantanément à la demande, même lors des pics de froid hivernaux. Le mécanisme incite financièrement les producteurs à maintenir leurs centrales disponibles et les entreprises à réduire leur consommation (effacement) lors de ces périodes critiques.

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.

C'est l'indicateur d'efficacité d'un appareil électrique ; il représente le ratio entre la puissance active (utile) et la puissance apparente (totale).
.png)
La Vente de Nucléaire Universelle (VNU) est le nouveau mécanisme de régulation des prix de l'électricité en France. Contrairement à l'ARENH, il ne s'agit plus d'un volume fixe à prix réduit, mais d'une redistribution financière des revenus excédentaires d'EDF aux consommateurs, basée sur les prix de marché et les coûts de production du nucléaire historique.

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 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.

Chaque modèle d'IA répond à un besoin spécifique du cycle d'achat :
L'expertise humaine reste néanmoins indispensable.

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.

Absolument. La réforme des heures creuses vise à absorber la surproduction solaire en milieu de journée. Les créneaux d'heures creuses se déplacent progressivement vers la plage 11h00 – 17h00, notamment en été. C'est une opportunité majeure pour les sites industriels ou tertiaires capables de flexibilité.
Conseil stratégique :
.png)
Ce seuil est jugé élevé par rapport aux prévisions actuelles du marché. Si le prix de l'électricité reste en dessous de 78 €/MWh, les entreprises ne bénéficieront d'aucune redistribution. Cela signifie que la protection promise par la réforme pourrait être inexistante dans un marché baissier, d'où l'importance de stratégies de sourcing agiles et d'outils de monitoring comme Pilott.

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.

Non. L'IA traite la donnée (data processing), mais l'analyste apporte la compréhension du contexte (market sentiment) et la prise de décision stratégique.

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.

Ce record de 92,3 TWh s'explique par la conjonction de trois facteurs :
.png)
L'augmentation s'explique par la revalorisation de l'Accise sur le gaz à 16,39 €/MWh et la hausse de 3,41 % du tarif de transport (ATRT 8).
S'y ajoute l'entrée en vigueur des Certificats de Production de Biogaz (CPB), un nouveau coût réglementaire pour soutenir le biométhane.
Face à ces évolutions, Sirenergies vous accompagne dans l'achat de gaz naturel pour sécuriser vos prix malgré la volatilité du marché.

Le prix Forward est fixé à l'avance (sécurité budgétaire), tandis que le prix Spot varie heure par heure selon le marché (opportunité mais risque élevé).
.png)
The €/MWh is a price unit used in wholesale markets, while kWh is the unit visible on your bills.
.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.

The range E @sy is available in four pricing structures to adapt to each risk profile:
.png)
En 2025, la France a atteint un solde exportateur net de 92,3 TWh, battant le précédent record de 2024 (89 TWh).
.png)
L'impact dépendra des prix de marché. Le mécanisme prévoit une redistribution si les prix dépassent 78 €/MWh. Cependant, si les cours restent bas (actuellement autour de 60 €/MWh), le dispositif ne s'activera pas. La facture sera alors indexée à 100% sur les prix de marché, rendant le choix du fournisseur et du moment d'achat critiques.
.png)
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 :
.png)
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.
.png)
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.
.png)
This makes it possible to choose the right time to contract, secure your budgets and anticipate increases.
.png)
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.
.png)
Car les marchés dépendent de facteurs exogènes imprévisibles (géopolitique, météo soudaine, politique) que les modèles basés sur l'historique ne peuvent pas anticiper, tout comme on ne prédit pas le Loto.
.png)
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.
.png)
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.
.png)
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.

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.
.png)
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.
.png)
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.

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.
.png)
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.
.png)
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).
.png)
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.

Parce que la puissance souscrite en kVA détermine le prix de l'abonnement et que tout dépassement peut entraîner des surcoûts importants.

The central objective of PPE 3 is to engage France towards carbon neutrality by 2050 by breaking the country's historical dependence on fossil fuels.
Today, approximately 60% of final energy consumption in France still relies on imported oil and natural gas. PPE 3 aims to radically reverse this trend by setting an ambitious target: to reach 60% of carbon-free energies in final consumption by 2030.
To achieve this, PPE 3 pursues three major sub-objectives:
