At the beginning of autumn 2021, in France, we broke a historic record. Unfortunately, this is not the Tokyo Olympic Games, but an otherwise serious subject. In fact, Electricity prices are peaking at an all-time high.
The symbolic mark of €100/MWh has been exceeded several times. This global situation is likely to explode the Business Invoice and French households.
The French government is on the alert on this very sensitive subject. Prime Minister Jean Castex announced a series of measures aimed at reducing the impact of these variations on the purchasing power of the French. For example, the tariff shield, the energy check as well as discussions around a potential reduction in VAT on energy.
But why has the price of electricity increased stratospherically in recent months? In reality, it is the conjunction of several events. The set of energy prices is experiencing an unprecedented rise.
Gas, oil and coal prices react in a correlated manner. They are markets interdependent. For example, a rise in oil prices often causes other indicators to rise.
Contrary to usual, black gold is not responsible for the variations we see today. As we will see, the post-Covid recovery of activity as well as gas or CO2 prices are the main responsible for current prices.

If we want to understand this rise in electricity prices, we must be interested in CO2 markets. Indeed, the price of CO2 has exploded in recent years. The price of CO2 emission allowances leads in its wake to the price of electricity.
Indeed, the CO2 market had efficiency problems until 2018. This quota system is supposed to reduce and encourage polluters to reduce their emissions. However, until now, it had too many quotas available on the market.
The establishment of a stability reserve has made it possible to reduce the number of quotas on the CO2 market. Mechanically, the price of CO2 has increased significantly. Electricity producers, who have to buy as many quotas as emissions, pass on this increase to their prices. For this reason, electricity prices increased during the first half of 2021.
Currently, the most impacting factor in electricity prices is the price on wholesale gas markets.
There are several factors that explain this price increase. First of all, the resumption of activity Post-COVID is one of the important explanatory factors. Nuclear power plants are back in business, but are not at their optimum level. La requisition of gas is increasing, but, at the same time, gas production is not yet at its maximum level.
The new Nord Stream 2 gas pipeline is still in the process of being certified and the offer is therefore still rare. Analysts believe that its inauguration should allow prices to fall again.
The strong demand for liquefied natural gas (LNG) coming in particular from Asian countries is also one of the factors driving up prices.
All of these events are causing natural gas prices to rise. It should then be remembered that the price of gas is one of the drivers of electricity markets. In fact, in order to satisfy the demand of the French, means of producing electricity are successively called.
First of all renewable, nuclear, then gas and coal-fired power plants. These power plants are listed in order of production costs. We call from the cheapest power plant to the most expensive. And it is the production cost of this last power plant called that literally makes The market price. That's what we call the Merit Order.
Generally, when demand is high, it is therefore the cost of gas-fired power plants that is retained. Thus, an increase in gas prices inevitably leads to an increase in electricity costs., because the price of fuel used to produce electricity (gas) is soaring.
This price increase will also affect regulated sales rates for individuals and does not only affect professionals.
First of all, it should be remembered that energy management strategies (EMS) are long-term strategies. Generally, electricity contracts for businesses are discussed one or even several years in advance with their electricity suppliers.
Certainly, there are certain supply offers that allow some of the electricity volumes to “run” on short-term markets. You sign the contract in advance, but you have to stay alert to price changes. But it is an anticipated risk that is part of the company's strategy.
The process of covering your electricity volumes in advance makes it possible to set a budget and not to be sensitive to these price spikes. Anticipation is a key concept in energy purchases.
All this will depend on the type of contract signed by the company. However, there are clauses that can reduce the impact of these bill increases. For example, the purchase of rights clause ARENH. Despite a Clipping Every year more important, ARENH can make it possible to reduce price increases (€42/MWh compared to more than €100 today).
The contractual strategy put in place makes it possible to be protected from these price changes or, at least, to control the risk.
There are other ways in which it is possible to reduce dependence on the public electricity network. Indeed, it is possible to subscribe to long-term energy purchase contracts.
There are producers of renewable origin who agree to be paid at a price fixed in advance: this is what we call Power Purchase Agreement (PPA). This allows them to be sure of their income while guaranteeing a supply for the customer. Generally, this production is of renewable origin.
These long-term contracts represent an alternative to 100% market sourcing.
Again, these are contracts signed in advance. Anticipation is a key factor in energy purchases.

It is also possible to produce your own electricity. Indeed, to do without the electrical network (and therefore indirectly price increases), it is possible to produce electricity from photovoltaic installations.
These projects of self-consumption make it possible to increase its energy independence while reducing its costs. Again, this is a project to be implemented, but whose implementation time is relatively short. This also contributes to the development of renewable energies.
In conclusion, we can recall that energy purchases require a long-term study in order to implement a cost strategy. It is essential to be accompanied in this process by advice with expertise on the subject. It will be necessary to monitor price developments in the coming months. Winter is likely to be tense on European markets.
Electricity, gas and CO2 prices change every day and are important to follow for buy at the best time.
Beyond supporting you in your energy optimizations, our vision is to give you this transparency in real time. Price data allows you to make better decisions for your business.

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.

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.

Ce record de 92,3 TWh s'explique par la conjonction de trois facteurs :
.png)
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.

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

This makes it possible to choose the right time to contract, secure your budgets and anticipate increases.

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

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.

En 2025, la France a atteint un solde exportateur net de 92,3 TWh, battant le précédent record de 2024 (89 TWh).

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.

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

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.

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.

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 :

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).

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

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)
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.

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.

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.

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 :

La réussite d'un projet collectif énergie repose sur trois piliers fondamentaux :

The €/MWh is a price unit used in wholesale markets, while kWh is the unit visible on your bills.
.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.
.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.

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.
.png)
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)
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.

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.
