At the dawn of their 20th anniversary, energy savings certificates (EECs) are singled out by the Court of Auditors. In a press release dated September 17, 2024, the institution called for an in-depth reform of the system. “more and more complex”, generating “increasingly important costs” And victim “significant fraud phenomena”. Its real effectiveness is in doubt. The energy savings achieved would be “significantly overrated”.

Would everything be good to throw into this device at the heart of France's energy policy since 2005? What is certain is that the conclusions of the Court of Auditors should influence the arbitrations of the sixth period of the EECs 2026-2030. A look back at this energy transition mechanism and its future prospects.

The EEC system: how does it work?

Les energy savings certificates (CEE) were created in 2005, with the POPE program law of 13 July 2005 setting out the guidelines for energy policy. With this system, France was then at the forefront of the energy transition.
The objective? Encourage businesses, professionals and individuals financially to save energy.

The EEC principle: “polluter pays”

The mechanism of energy savings certificates is complex. At the heart of the system: the required actors. They are called that because they have theobligation to obtain a certain volume of EECs for a given period of time, under penalty of financial sanctions. These certificates attest to the quantities of energy saved thanks to their actions.

The volume of CEEs is set by the State by period. It is shared between the actors obliged in proportion to their energy sales.

The obligated actors are the energy suppliers (electricity, natural gas, LPG, heat, cold, fuel oil) and fuel distributors. Among them are big names like EDF, Engie, TotalEnergies, Leclerc, Auchan or Carrefour.

Other actors who are not required are eligible for the scheme. These are local authorities, public institutions, the National Housing Agency (ANAH) and social landlords.

How does the CEE system work?

For achieve energy savings and to obtain their CEE volume, the “obliged” actors have three possibilities:

  • Carry out their own energy saving work to contribute to the achievement of the overall objective.
  • Buy energy savings certificates on the organized CEE market, orchestra of the encounter between sellers and buyers.
  • Helping consumers to carry out renovation and energy efficiency work through the “Coup de Pouce” grants. The supplier obtains 1 energy savings certificate for 1 kWh cumac of energy savings achieved by its customer. We have thus seen the multiplication of “energy premium”, “CEE premium” or even “eco-energy bonus” offers, dedicated to thermal insulation, boiler replacement and, more recently, to the installation of a heat pump. Suppliers are free to set the amount of their financial contribution to eligible energy performance works. They are also free to define the form of their aid (bonuses, vouchers, free services, discounts, etc.).

Les EEC obtained by the obligated actors are delivered directly to their EMMY account in the national digital register.

A bit of history: the five periods of CEEs

Since 2005, five EEC periods have succeeded one another. Energy saving goals have been affirmed from period to period. The increase of more than 4,000% in bonds between 2005 and 2022 is dizzying and reflects France's ambitions.

The first EECs' transition period (2005-2010)

When the system was launched, the State set a reasonable energy savings target of 54 TWh cumac (the kWh cumac is the unit used in calculating the obligation). This objective was largely achieved at the end of the period, with more than 65.3 TWhc saved.

The second CEE period (2011-2014)

Following the success of the first period, the energy savings objective increases to 447 TWh cumac. THEbroadening the scope of obligated actors compensates for this spectacular increase, with the integration of fuel distributors.

The third CEE period (2015-2017)

The objective of saving energy is almost multiplied by two. The ambition is set at 700 TWh cumac, to meet European requirements in terms of energy reduction.

During this period, the standardization of documents And a declarative application process are put in place. The EEC precariousness is born. It requires an additional 150 TWhc to be dedicated to the fight against fuel poverty.

The fourth EWC period (2018-2021)

The objective of saving energy, of 2,133 TWhc, always follows an upward curve.

The fourth EEC period highlights some limitations of the EEC system. The law is evolving to fight fraud. The control order of September 28, 2021 reinforces systematic and random checks. It tightens quality requirements and lowers the threshold for authorized non-compliant transactions.

The fifth EWC period (2022—2025)

Over this fifth period, the objectives achieved 2,400 TWh cumac, in line with European and national energy transition objectives.

This period is marked by the strengthening of EEC aid to the most modest households. The distribution of obligations between suppliers is also changed., illustrating France's desire to decarbonize. Gas and oil suppliers saw their obligations increase by 83% and 52% respectively, while electricity suppliers saw their bond ratio fall by 11%.

EEC: a mixed record

In 2023, consultation was launched to set the modalities and objectives for the sixth EWC period. Today is the time to take stock. A mixed balance according to the conclusions of the Court of Auditors report published in September 2024.

Real energy savings

Even if they would be overestimated by at least 30% according to estimates by the Court of Auditors, real energy savings have been achieved since 2005 thanks to theacceleration of energy efficiency works.

According to figures from the Court, more than 1 million operations have been financed every year since 2021. And from 2014 to 2020, the CEE system “would have made it possible to reduce energy consumption in France by 106 TWh in 2020, or 6.5% of it.”

In 2024, the CEEs are supporting nearly 200 types of energy saving work. Businesses, industries and households can benefit from EEC aid for their workisolation building thermal systems, the energy renovation, the replacement of equipment heating, regulation, hot water or ventilation (heat pump, thermostat, high energy performance boiler, heat recovery unit, etc.) or the installation of a energy performance services contract.

But... an impact on energy bills

The EEC system has a direct impact on customers. Suppliers pass on to consumers the cost of obtaining energy savings certificates.

The Court of Auditors denounces a hidden energy tax. In 2023, each household contributed in this way “up to 164 euros on average under the EEC system, i.e. just over 4% of the amount of its energy bills ”.

But... a still high risk of fraud

At the end of the third CEE period, Tracfin, the agency of the Ministry of Economy and Finance responsible for these issues, noted an increase in fraud linked to energy savings certificates.

Swelling in the amount of work, overestimation of energy savings, fraudulent work ...: despite the strengthening of controls, this system leaves room for multiple scams, especially in the building sector. Like what happened with the carbon tax, Scammer networks also take advantage of the CEE system, with companies set up from scratch to recover the funds generated by the certificates.

But... a complex EEC system

Since its creation in 2005, the EWC system has undergone numerous developments. The level of obligation has increased. Of additional goals have been added, such as the precariousness CEE or temporary subsidies to support specific operations (boiler change, attic insulation, heat pump).

The rules “multiple and unstable” In the eyes of the Court of Auditors complicate, weaken and opacify the system.

What is the future for CEEs (2026—2030)?

There is no doubt that the report of the Court of Auditors will feed into the ongoing discussions on the sixth EWC period (2026-2030). The stakes are high as the 2030 deadline approaches. As part of the European “Fit for 55” package, France has in fact committed to reducing its final energy consumption by 30% in 2030 compared to 2012.

While France should not deprive itself of this financial incentive tool at the heart of its energy strategy, the in-depth reform of the EECs is defended by the Court of Auditors. To regulate and control the system, she calls for the simplification of the mechanism, the measurement of real energy savings after operations, the end of bonus practices, the automation of controls and the increased participation of Parliament. Another solution proposed by the Court: refocus energy savings certificates on the most precarious households.

In advance, the Directorate-General for Energy and Climate (DGEC) launched a Call for programs to evaluate the system of energy savings certificates. Its long-awaited conclusions will be decisive for the sixth EWC period.

The answers to your questions

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.

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.

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.

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.

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).

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.

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).

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).

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.

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 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 le kVA est-il crucial pour les entreprises ?

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

What is energy sourcing?

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.

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.

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.

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 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.

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.
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).

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 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
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 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.

Pourquoi ma facture de gaz va-t-elle augmenter en 2026 ?

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.

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.

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.

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.

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 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.
