For several months now, energy prices have been skyrocketing in Europe but also around the world. We are experiencing a crisis that is unprecedented in the young history of liberalized energy markets.
The previous record (93 €/MWh) in terms of electricity prices for the French market dated from 2008 and the subprime crisis. Since then, this price seems paltry in the face of the prices we currently know.
We have already mentioned the causes of this general increase in prices in Europe, but what about the last decade?
How have energy prices changed in 10 years? This is what we are going to try to explain, in particular by exposing the factors that can influence electricity and gas prices These two energies are complementary, and their developments have a direct impact on French companies.
When we talk about electricity prices, we must first specify what we are talking about in order not to create confusion. There are two types of awards to distinguish between:
The prices on wholesale markets influence regulated prices, but these can also be set by the public authorities. This is what we were able to observe with the establishment of the rate shield in 2022.
Regulated rates are established using the so-called “stacking” method. It is a method in which we will superimpose the various costs borne by The EDF group And the ELD (Local Distribution Companies) who have the right to charge at the regulated price.
One of these costs is precisely the price level on wholesale markets because EDF does not produce 100% of the electricity sold to French consumers. These concepts are therefore linked but care must be taken not to confuse them because they are potentially very different depending on time, political will, market conditions, etc.

It can be seen from this graph that regulated electricity prices fell relatively significantly over the decade 2000-2010. However, we do observe a gradual rise in prices over the last decade (2010-2020).
The yellow and green rates disappeared in 2015/2016, but the blue rates (individuals and professionals) experienced a increase of almost 25% over the last decade.
Contrary to some popular belief, this increase in rates is largely due to the increase in taxes as well as TURPE (Tariff for the use of public electricity networks). In the space of 10 years, taxes (in particular the CSPE) have increased cumulatively by more than 120%.
As far as the wholesale prices of the electricity markets are concerned, the situation is not the same. Unlike TRVs (Regulated Sales Rates), for which there has been a constant increase over the last decade, wholesale markets have remained fairly stable, with a particularly low trough in 2015-2016.
The increase in electricity prices in 2021-2022 is exceptional as shown by the graph below expressed in €/MWh. These price levels are around €200 or €300 on average are becoming the daily routine of energy traders.
The geopolitical situation The current situation in Europe suggests a sustainable rise in this price level. However, markets react very quickly to various geopolitical or economic signals. It will therefore be necessary to be attentive to it.
The historical record for the product Year+1 was beaten with a closing price of 389.30 €/MWh !
Regulated gas tariffs also change every year, sometimes experiencing major price movements. Whether up or down, gas prices have oscillated in a corridor of +20%/-20% in 10 years. Unlike electricity prices, which have only increased, significant decreases should be noted (2009, 2015, 2019).
We also see on this graph all the advantages of rate shield which has prevented tariffs from rising by more than 90 per cent with the current surge in prices.

Wholesale prices on gas markets (TTF and PEG) have experienced very important movements in the last few months. In question, the reduction of Russian supplies in Europe because of the protracted war in Ukraine.
The contributions of liquefied gas from the US are not enough to compensate for our level of consumption. Market tension is therefore continuing and Europe is preparing to spend next winter without this source of supply.
Europe's dependence on Russian gas (nearly 56 per cent) is therefore one of the factors to watch in an attempt to predict price movements in the gas market.
📈 At the close of July 4, 2022, The historical record for the product PEG Year+1 was beaten with a closing price of 108.24 €/MWh !
The availability of the French nuclear fleet is one of the factors that greatly affects the price of electricity in France.
More than 70% of production capacities areNuclear origin. When the unavailability of certain reactors is announced, this generates a price increase because the production volumes initially planned will not be produced.
As the supply of electricity becomes scarcer, its price automatically increases. Of corrosion problems have been reported on the French nuclear fleet. The effect of these announcements led to an immediate surge in the markets.
The European electricity market is based on the principle of Merit Order. The price of electricity on the spot market is determined by the various production costs necessary (nuclear energy, coal, gas, etc.) for its manufacture. These costs are listed in ascending order of price.
Then it's The price of the last power plant called (the most expensive) who is selected and who determines the final price.
This system is designed to allow all power plants to cover all of their costs, otherwise they would not be profitable. Gas is therefore often the latter power plant, and therefore the price of gas (necessary for the production of electricity) thus determines the final price of electricity.
The recent establishment of a stability reserve on this market has made it possible to reduce the number of quotas on The CO2 market. Once again, market laws tell us that this increases the price of CO2. Electricity producers have to buy as many allowances as CO2 emissions, so they include this cost in their selling prices. This is one of the major causes of the rise in prices in 2021.
Individuals are now protected by the tariff shield decided by the government. Medium-sized businesses, on the other hand, are the most exposed to these significant price changes.
It is necessary for these companies to set up a energy risk management policy. This cost must be anticipated, as markets are complex, it is more than necessary today to be supported by specialists in the sector.
It is entirely possible to subscribe to contracts with negotiated prices at appropriate times and so secure its supply over the long term. It is possible to use attractive tariff formulas and devices to smooth the price of energy over a certain period of time.
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.

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).

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.

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.

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.

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:

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.

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)
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.

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.

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.

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

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.

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.

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.

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.

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

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 :

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.
