The ARENH 2025 window closed this Friday, November 29, 2024.
For you, consumers and customers, this device dedicated to electricity suppliers may seem remote and obscure and may not concern you.
Think again. The ARENH law of suppliers has a direct impact on your energy bill.
In recent years, traffic jam has contributed to the rise in electricity rates. You are concerned as soon as you have taken out an electricity contract with ARENH indexed prices.
But what is clipping? What is its impact on invoices? Can businesses take action now to limit the impact on their energy costs?
Here is all the information on ARENH to anticipate and secure your electricity budget.
What is the ARENH device?
ARENH, a system in favor of competition
The ARENH system was set up in 2011 by The NOME law on the New Organization of the Electricity Market, following the work of the Champsaur Commission.
This device aims to promote fair competition between the historical electricity supplier, EDF, and alternative suppliers.
The objective? Ensuring affordable electricity prices for all consumers, as part of The opening of energy markets to the competition in France.
Regulate access to historic nuclear electricity
ARENH signifies Regulated Access to Historic Nuclear Electricity. Thanks to ARENH, each alternative supplier can cover part of the electricity consumption needs of its customers by buying a share of Nuclear power generation. This access to more competitive electricity promotes the control of the prices of electricity offers.
What is ARENH capping?
What is the ARENH ceiling?
The volumes of nuclear electricity sold at advantageous prices by EDF to alternative suppliers are capped by law. This cap was put in place to preserve the financial capacities of the main French electricity producer and supplier.
For many years, The ARENH ceiling is set at 100 TWh, with an exceptional increase to 120 TWh in 2022. This ceiling corresponds to around a third of France's current nuclear production.
Why the clipping?
ARENH's 100 TWh is divided between all alternative suppliers who have filed an ARENH application with the Energy Regulatory Commission (CRE). However, since 2018, the total volume of ARENH requested by all suppliers has exceeded the ARENH ceiling.
The clipping mechanism was put in place to regulate requests and Guarantee access to historic nuclear electricity for all, within the framework of healthy competition.
The capping is based on the following principle: allocating a share of ARENH, even partial, to all suppliers, rather than giving 100% of their demand to some and 0% to others.
How do you calculate the ARENH peak?
The capped ARENH portion corresponds to the calculation of Difference between the overall volume of ARENH requested by alternative suppliers and the annual ARENH limit available.
Evolution of ARENH orders (in TWh) since 2018:
For example, for the year 2024, the total quantity of ARENH requested was 130.41 TWh for a maximum volume of 100 TWh. The CRE therefore carried out a shearing of 30.41 TWh, i.e. a shearing rate of 23.32%.
In concrete terms, this means that the alternative suppliers have all seen their ARENH demand met by 76.68%.
ARENH 2025: what peak?
This Friday, November 29, 2024, as part of the historic ARENH 2025 regulated access to nuclear electricity mechanism, the CRE (Commission de Régulation de l'Énergie) has just announced the allocation rate.
It amounts to 74.12% with a controlled volume of 134.93 TWh, i.e. a peak of 25.88% (versus 23.32% in 2024).
The CRE recalls that the quantity of electricity allocated to suppliers has been set at a price of €42/MWh and is still capped at 100 TWh for the year 2025.
The impact of ARENH capping on electricity suppliers' offers
All consumers who have subscribed to ARENH indexed price contracts are entitled to a share of electricity from nuclear sources at a more competitive rate. But The locking mechanism reduces everyone's ARENH right, with repercussions on electricity bills.
Indeed, alternative suppliers must buy the limited portion of electricity on the energy market. However, prices on the wholesale market are volatile and much higher than those for nuclear electricity. The ARENH is now fixed at €42/MWh. These higher supply prices are passed on by suppliers in their electricity offers, with an upward revision of contract rates.

Regardless of the supplier, a high ARENH cap rate therefore results in a Inevitable increase in bills electricity for consumers, businesses, communities and individuals.
Businesses: what solutions are there to limit the impact of ARENH capping?
As a business, you don't have no control of the ARENH locking mechanism applied by CRE. But you can take action to limit its impact on your electricity bills.
Subscribe to an electricity offer under ARENH 2024 conditions
In the short term, to secure your energy budget, you can subscribe to a new electricity offer before the ARENH 2025 counter. Until December 31, 2024, you can still benefit from the known and advantageous pricing conditions of ARENH 2024.
Anticipate the purchase on the market on your part ARENH limited
If you anticipate significant ARENH losses, you can also ask your energy supplier tobuy your capped electricity share in advance on the market, without waiting for the end of the year when prices are in the habit of soaring.
However, this requires expert knowledge to estimate the ARENH limit and identify the most financially favorable period for the supply of electricity on the wholesale market.
Control your energy consumption
In the longer term, the best way to lower your electricity bill is to reduce your consumption at the source. Investing in energy sobriety, energy efficiency and renewable energies, it is the winning trio to control your energy expenses and improve your carbon footprint.
Towards the end of ARENH
The end of ARENH is announced for December 31, 2025. The State and EDF signed a first agreement in November 2023, outlining the outlines of the new price control system from 1 November 2023.Er January 2026. However, voices are being raised to call for new negotiations in 2025.
Encouraging long-term contracts
EDF is banking on the signing of long-term contracts of at least 5 years. This period should allow businesses to secure their energy supply, by benefiting from a better visibility on prices.
With more stable prices, long-term contracts must protect companies from market vagaries and optimize energy purchases.
The creation of a redistributive system
The bill provides for a Nuclear universal payment financed by a nuclear contribution. These would be levied on sales of electricity produced by the national nuclear park, above a reference price.
EDF and the State have set the nuclear energy reference price around €70/MWh. The bill provides for a 50% levy of EDF's additional income when the price increases between €78 and €110/MWh. This rate rises to 90% above €110/MWh.
To avoid an increase in electricity prices, the revenue collected will be directly redistributed to consumers individuals and professionals, regardless of their supplier. However, the terms of this payment remain to be specified.
The extension of TRV to sites greater than 36 kVA
The regulated electricity sales tariff is now available to companies with less than 10 employees, whose turnover does not exceed 2 million euros and whose subscribed power is less than 36 kVA.
The law of 11 April 2024 removed this last threshold. From the 1Er February 2025, all companies meeting the workforce and turnover conditions will be able to subscribe to a TRV contract regardless of the power subscribed.
Until the end of ARENH, suppliers will communicate to their customers in January 2025 the new electricity rate applicable to their contract for the year. These will have to take into account the share of ARENH allocated and the share of electricity purchased at the end of 2024 on the wholesale market.
SirEnergies recommends that you check your first invoices carefully to ensure that your supplier did not make a mistake in calculating any additional costs associated with the ARENH cap.
Our experts are at your side to optimize your energy purchases and anticipate the end of ARENH today.

The answers to your questions
Pourquoi le kVA est-il crucial pour les entreprises ?
.png){kind=icon}
Parce que la puissance souscrite en kVA détermine le prix de l'abonnement et que tout dépassement peut entraîner des surcoûts importants.
What are the PP1 and PP2 alert days?
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.
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.
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.
Quel est le nouveau record 2025 d'exportation d'électricité de la France ?
En 2025, la France a atteint un solde exportateur net de 92,3 TWh, battant le précédent record de 2024 (89 TWh).
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 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.
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.
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.
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.
Pourquoi mon contrat est-il en kVA et ma consommation en kWh ?
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.
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.
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.
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.
L'hydroélectricité est-elle une énergie "propre" ?
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).
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.
Pourquoi la France a-t-elle exporté un volume record d'électricité en 2025 ?
Ce record de 92,3 TWh s'explique par la conjonction de trois facteurs :
- Le redressement du parc nucléaire : Après les problèmes de corrosion sous contrainte de 2022, la production nucléaire a retrouvé une forte disponibilité (373 TWh).
- L'essor des renouvelables : Une capacité installée en hausse (solaire et éolien) et une production hydraulique solide.
- Une consommation intérieure atone : La demande française reste inférieure de 6 % à la moyenne historique, créant un surplus massif disponible pour nos voisins.
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.
Quelle est la différence concrète entre le transport et la distribution d'électricité ?
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.
Comment l'eau est-elle transformée en électricité ?
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 :
- Le barrage retient l'eau et l'oriente vers des conduites.
- La pression de l'eau fait tourner une turbine, créant de l'énergie mécanique.
- Une génératrice (alternateur) transforme cette énergie mécanique en électricité, laquelle est ensuite adaptée par un transformateur pour le réseau
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.
Quel est l'impact de ces exportations sur le prix de l'électricité pour les entreprises ?
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.
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.
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).
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.
How to optimize taxes and contributions?
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.
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.
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.
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.
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.
Qu'est-ce que le cosinus phi
C'est l'indicateur d'efficacité d'un appareil électrique ; il représente le ratio entre la puissance active (utile) et la puissance apparente (totale).
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.
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.
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.
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 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.
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.
Is Bellenergie Business electricity really green?
