At a time of energy transition, it is crucial to be able to project yourself into the future and to foresee several scenarios. Indeed, public authorities will have to make absolutely crucial decisions concerning the future of energy in France.
What are the preferred production methods (nuclear power plants, renewable energies, biogas, etc.)? What will our level of global electricity consumption be in 2050? What will be the new electrical uses and needs of tomorrow?
These questions are essential in order to be able to build a coherent and efficient French energy landscape in the years to come.
Planning has often been at the center of all large-scale industrial developments during the 20th century. The French nuclear program, started in the 1970s, was the result of a reflection on the independence of France from an energy point of view.
The need not to depend on hydrocarbon exporting countries has prompted the French presidency to speed up on the subject.
Today, the thoughts are different. A full member of Europe, France is trying to imagine its future needs through the prism of European solidarity. The electrical system is interconnected and countries are dependent on each other.
In 2021, RTE has therefore attempted to do this by proposing a very serious study that tries to draw the different possible scenarios. We are therefore going to try to immerse ourselves in this study that is highly anticipated by the energy world. Here is the complete summary of Energy Futures 2050 by RTE.
RTE's methodology: an essential scientific approach
The framework of the study and the public consultation
It is crucial to discuss how this study was carried out. Indeed, generally, each theory mentioned in the world of energy is the subject of numerous questions in order to verify its reliability.
As this sector is mostly dominated by engineers, any lack of scientific rigor is frequently criticized. It is therefore very important to present the method used by RTE to try to imagine our future.
The project is divided into two main phases:
Source: RTE
RTE organized a large-scale public consultation that brought together nearly 4,000 organizations, institutions and individuals. The principle of public consultation is widely known and used in the energy sector. However, the quantity and precision of the responses indicate genuine interest on the part of the population as a whole.
The phase of publishing the results
The culmination of this project remains the publication of the results of the study on October 25, 2021. Indeed, after drawing lessons from the scoping phase and then carrying out the studies, the project makes perfect sense when the data is published.
This study was highly anticipated in the sector, but the general public only knew about its existence when it was published.
This document is supposed to serve as an energy compass for public authorities. However, it is likely to create a lot of debate, and sometimes confusion. To do this, it is enough to note certain political statements.
At SirEnergies, we like rely on facts and analyze an approach before criticizing it. It turns out that the consultation efforts, as well as the approach and the numerous parameters analyzed, allow us to attest to the seriousness of this study.
However, there are some points to be clarified that we will see in this article. However, given the complexity of the exercise, it is quite normal to see grey areas appear.
The content of the RTE study Energy Futures 2050
An exhaustive and detailed analysis
As electrical system manager, RTE is a player at the heart of the energy transition. It fulfills its public service mission, while developing its R&D activities.
He is therefore an actor who, thanks to his technical skills and his experience of network manager, can answer a lot of questions. The aim of this study is to anticipate: to do this, RTE is trying to model all the different parts of the electricity sector. The problem is not only physical but also economic and social.
To set up these scenarios, RTE uses numerous parameters:
Source: RTE
These parameters are numerous, complex to capture and very often uncertain. It is extremely difficult to estimate the means of flexibility of tomorrow. In particular, they depend on economic incentives.
The aim of this study is to draw from these parameters several long-term scenarios. All of these scenarios are aimed at carbon neutrality By 2050. The aim of this study is therefore to establish several feasible scenarios (at least in theory) in order to achieve the goals of reducing CO₂ emissions.
It should be understood that this study is not aimed at calculating the optimal situation (the least expensive and the most effective), but rather several plausible scenarios.
Obviously, these projections are subject to hazards, but also to numerous political and social choices.
Energy strategy 2050 — The various scenarios under study
RTE has therefore put in place scenarios of different energy mix in France by 2050. But it is also about different consumption trajectory scenarios.
To simplify and summarize this work, we will first study the three scenarios that do not foresee any nuclear capacity under construction (Scenario M).
M scenarios — Source: RTE
These scenarios are back-tested several times. RTE tells us that, theoretically, it is possible to support the electrification of uses thanks to these various packages.
The spotlight is on renewables : solar panels, as well as wind power, represent most of the means of production. They are part of a national low-carbon strategy that is supposed to help us reach our goals.
The M0 is also a scenario without any nuclear energy ; the other two have no new capabilities. Nevertheless, it is interesting to note that RTE did not carry out the economic analysis of the M0 scenario. The development of renewable energies is nevertheless essential; it remains to be seen in what proportion.
In all these scenarios, the means of flexibility are essential, as they are the ones that reduce the effect of The intermittency of renewable energies. In particular, they all use an installed capacity of 1.7 GW of electric vehicles (V2G Vehicle to Grid). Indeed, security of supply is fundamental.
Finally, here are the scenarios N, which present a French energy landscape with new nuclear capabilities.
N scenarios — Source: RTE
These electrical mixes are more varied and have the merit of being, at the same time, more realistic. They highlight nuclear, modular and decarbonized technologies.
We therefore see the corollary of what we said earlier: the means of flexibility are clearly decreasing in these scenarios.
Source: RTE
As we have said, it is impossible to dissociate means of production and electricity consumption. Different scenarios emerge, with several variants.
However, we decided to summarize the main lessons of this report:
- Regardless of the scenario, electricity consumption is likely to increase in the coming decades.
- It seems economically relevant to invest in nuclear power in order to maintain an installed capacity of around forty GW.
- It is impossible to achieve carbon neutrality without significant development of renewable energies.
- ENR have become competitive and the development of offshore wind energy is a solid alternative.
- The energy transition will require a modification of the electrical network. As RTE says very well: “Over the next few years, network connections will increase and the pace of connection is a technical and organizational challenge.”

So this study is comprehensive, dense and, like any study Foresight, uncertain. However, it is an absolutely essential exercise in order to give food for thought to tomorrow's decision-makers. Energy is a long, even a very long term industry. It requires investments, which are often massive.
Before investing, it is crucial to have tangible elements that can support or disprove certain investment projects. This is the role of this study, but there is no doubt that this exercise will increase over time in order to have an ever more precise vision of the immense challenges that await the world of The energy of tomorrow.
This study also has the merit of stimulating public debate and thus allowing citizens to take ownership of the subject. The energy sector is not quite like the others, it is essential and deserves this kind of long-term thinking. In all cases, economically viable technologies will have to be found in order to replace fossil fuels.

Did you know that?
Resulting from a desire of the French government, the Tertiary Eco-Efficiency System (DEET), also called Tertiary decree, requires a gradual reduction in energy consumption for French tertiary buildings greater than 1,000 m².
This regulation aims to save 60% of final energy in these buildings by 2050.
We support you in the compliance tertiary buildings in order to comply with the obligations of the tertiary decree.

The answers to your questions
Pourquoi le seuil de 78 €/MWh est-il critiqué par les experts ?
.png){kind=icon}
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.
Quels sont les cas d'usage concrets des différents types d'IA pour un acheteur d'énergie ?
Chaque modèle d'IA répond à un besoin spécifique du cycle d'achat :
- L’IA générative sert d'assistant de recherche pour synthétiser en quelques minutes des rapports de marché massifs (veille stratégique).
- L’IA déterministe est l'outil de la fiabilité : elle est indispensable pour le forecast (prévision de consommation) car ses calculs sont mathématiques et reproductibles.
- L’IA probabiliste est dédiée à la gestion des risques : elle simule des scénarios (ex: météo, stocks) pour quantifier l'incertitude sur les budgets futurs.
L'expertise humaine reste néanmoins indispensable.
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 is the Multiannual Energy Programming (PPE)?
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:
- Security of supply.
- Improving energy efficiency and reducing consumption.
- The development of renewable and recovered energies.
- The electrical production strategy (nuclear, thermal, etc.).
- The balanced development of networks and storage.
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.
Quel sera l'impact réel du VNU sur ma facture d'électricité professionnelle ?
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.
Pourquoi l'IA ne peut-elle pas prédire le prix de l'énergie avec exactitude ?
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.
Quelle est la différence entre un prix Forward et un prix Spot ?
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).
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).
Why is Scope 2 crucial for CSR?
It allows you to prove your commitment to the energy transition and to meet regulatory requirements.
Fin de l'ARENH au 31 décembre 2025 : comment sécuriser mon budget énergie pour 2026?
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 :
- Le Versement Nucléaire Universel (VNU) : Ce n'est pas un tarif d'achat, mais un mécanisme de redistribution a posteriori. Si les prix de marché de l'électricité nucléaire dépassent un certain seuil (environ 78 €/MWh selon les estimations pour 2026), EDF reversera 50 % des revenus excédentaires aux consommateurs. Attention : Si les prix de marché restent modérés (sous les 78 €/MWh), le VNU ne se déclenche pas. Il agit comme une assurance contre les flambées extrêmes, pas comme un tarif bas garanti.
- Les CAPN (Contrats d'Allocation de Production Nucléaire) : Réservés aux industriels électro-intensifs, ces contrats de long terme (10-15 ans) permettent de réserver une part de la production nucléaire en échange d'une participation aux coûts du parc. Ils offrent une visibilité sur le long terme pour 50 à 70 % des volumes consommés.
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.
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.
L'IA remplace-t-elle les analystes en énergie ?
Non. L'IA traite la donnée (data processing), mais l'analyste apporte la compréhension du contexte (market sentiment) et la prise de décision stratégique.
What is the difference between Scope 1 and Scope 2?
- Scope 1 concerns direct emissions (combustion on site),
- Scope 2 deals with indirect emissions related to purchased energy (electricity, steam).
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.
Pourquoi le mécanisme de capacité a-t-il été créé ?
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.
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 is the main objective of the Multiannual Energy 3 Programming?
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:
- Massive decarbonization: Replace fossil fuels with low-carbon electricity or renewable heat in industry, transport and buildings.
- Energy sovereignty: Reduce the national energy bill (around 60 billion euros per year) and get rid of the volatility of the global gas and oil markets.
- Economic competitiveness: Guarantee businesses and households access to stable, abundant and predictable energy at a predictable cost, disconnected from geopolitical crises.
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.
Qu'est-ce que le dispositif VNU qui remplace l'ARENH en 2026 ?
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.
Mon entreprise peut-elle tirer profit des nouvelles Heures Creuses (11h-17h)?
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 :
- Pilotage de la charge : Si vous avez des processus énergivores (fours, broyeurs, recharge de flotte de véhicules électriques, production de froid), déplacez leur fonctionnement sur la pause méridienne. L'électricité y sera moins chère et moins carbonée.
- Autoconsommation : C'est le moment idéal pour coupler cette tarification avec une installation photovoltaïque en toiture ou en ombrière de parking. Vous effacez votre consommation réseau au moment où le tarif serait le plus avantageux, ou vous profitez des prix bas du réseau si votre production ne suffit pas.
