The end of the Regulated Access to Incumbent Nuclear Electricity (ARENH) on December 31, 2025, marks a turning point for French companies,,. Introduced in 2011, ARENH allowed alternative suppliers to access EDF's nuclear electricity at a regulated price of €42/MWh,,. This regulation will end, exposing companies to the volatility of the electricity market,.

End of ARENH in 2026 and Exposure to Market Volatility

From 2026, companies will have to procure electricity directly from the market, where prices are likely to vary considerably depending on supply and demand, weather conditions, and geopolitical events. Negotiated contracts already indicate a price increase, ranging from €57 to €75/MWh, an increase of 35% to 80% compared to the ARENH tariff,.

Introduction of the Universal Nuclear Payment (VNU) and its Operation

The Universal Nuclear Payment (VNU) is the mechanism put in place to succeed ARENH,,,. Its objective is to redistribute EDF's revenues when market prices exceed certain thresholds,,,. The Energy Regulatory Commission (CRE) has set a pivot value of €60.94/MWh for EDF's nuclear revenues. According to the CRE, nuclear production costs are estimated at €60.3/MWh for the period 2026-2028,.

Anticipating the Potential Increase in Energy Costs

The end of ARENH and the introduction of the VNU imply a risk of increased energy costs for companies,,. Although the VNU is designed to mitigate the impact of price volatility, it may not offer sufficient protection in all situations,,. It is therefore crucial for companies to anticipate this potential increase and implement strategies to optimize their consumption and secure their supplies.

Strategy #1: Optimize Energy Efficiency

Optimizing energy efficiency is an essential strategy to reduce the impact of the end of ARENH on companies' energy costs,,,. By reducing their consumption, companies reduce their dependence on the market and protect themselves against price fluctuations.

Identify Areas for Improvement in Energy Consumption

The first step is to identify the main energy consumption items within the company. This can be done through an energy audit, which will highlight areas of waste and opportunities for improvement,. Areas to examine may include lighting, heating, ventilation, air conditioning, industrial equipment, and production processes.

Assess the Feasibility and Profitability of Each Option

Before choosing a renewable energy option, it is important to assess its feasibility and profitability based on the specific characteristics of the company. Factors such as geographic location, resource availability, installation and maintenance costs, and available financial incentives should be taken into account.

Combine Different Sources to Secure Supply

To secure the energy supply, it may be wise to combine different sources of energy, both renewable and non-renewable. This approach reduces dependence on a single source and provides greater flexibility,.

Strategy #3: Secure Prices with Long-Term Contracts

Negotiating long-term supply contracts is an effective strategy to protect against market price volatility,,. These contracts allow you to fix a price for electricity over a specified period, providing visibility and budget stability.

Negotiate Long-Term Supply Contracts with Suppliers

It is important to carefully negotiate long-term supply contracts with electricity suppliers. It is advisable to compare offers from several suppliers and to be supported by an expert to analyze the contractual clauses and ensure that they are favorable to the company,.

Analyze the Different Offers and Contractual Clauses

Contractual clauses can have a significant impact on the cost of electricity. It is important to check the clauses relating to price revision, penalties in the event of non-consumption, and the conditions for terminating the contract.

Protect Yourself Against Market Price Volatility

Long-term contracts may include mechanisms to protect against price volatility, such as indexation clauses or options to purchase electricity at a fixed price. These mechanisms limit the impact of market fluctuations on the cost of electricity.

Strategy #4: Monitor the Market and Adapt

The electricity market is constantly evolving, so it is essential for companies to stay informed of the latest trends and regulations,. Regular market monitoring makes it possible to anticipate changes and adapt one's strategy accordingly.

Stay Informed of Developments in the Electricity Market

To stay informed of developments in the electricity market, companies can subscribe to specialized newsletters, follow the publications of the CRE and RTE, and participate in events and conferences on energy. The Unisave teams ensure constant monitoring for their customers.

Adapt Your Strategy to New Regulations and Opportunities

Energy regulations are constantly evolving. It is therefore important for companies to adapt their strategy to new regulations and new opportunities, such as support schemes for renewable energies or Energy Savings Certificates (CEE).

Conduct a Regular Analysis of Energy Costs

A regular analysis of energy costs makes it possible to identify sources of waste and assess the effectiveness of the measures implemented to reduce energy consumption. This analysis can also help identify opportunities to negotiate more advantageous supply contracts.

The end of ARENH represents a challenge for French companies, but it also offers opportunities to become more efficient, more sustainable, and more competitive. By implementing the strategies presented in this article, companies can thrive in the new electricity market. Contact Unisave today to discuss your energy needs and discover how we can help you optimize your strategy.

From February 1, 2026, significant changes will impact the excise duty rates on electricity and gas. For electricity, the new rates will be €25.19/MWh for installations ≤ 36 kVA and €20.92/MWh for those > 36 kVA. Non-interconnected zones (NIZ) will see these amounts increased to €30.85/MWh (≤ 36 kVA) and €26.58/MWh (> 36 kVA).

The excise duty on gas will also increase, raising household bills by €12 to €80 per year. This increase is part of an objective to reach an excise duty rate of 12% by 2029.

A decrease in the Tariff Routing Contribution (CTA) is planned, partially offsetting the increase in excise duties. This decrease could represent a saving of around €10/year on the subscription [3, 5]. The Senate voted in favor of a reduction in taxes on electricity and an increase on gas, as part of the 2026 budget. This measure aims to rebalance energy taxation, although electricity remains more heavily taxed than gas (€25/MWh vs €10/MWh).

The French energy landscape is constantly evolving, and 2026 will bring its share of changes for businesses. Understanding these changes is essential to anticipate the impact on your electricity bills and optimize your energy budget.

Impact of Regulated Sales Tariffs (TRVE)

The Energy Regulatory Commission (CRE) has announced changes to the Regulated Electricity Sales Tariffs (TRVE), effective from February 1, 2026,,,,,. These changes mainly concern companies that have subscribed to the Tarif Bleu (Blue Tariff).

• Decrease in the non-residential Blue Tariff: For companies with a subscribed power ≤ 36 kVA, an average decrease of 1.29% excluding tax (1.58% including tax) is expected,.
• Elimination of the Green Tariff: The old Green Tariff will be eliminated. However, existing contracts will be maintained without changes,.
• Yellow Tariffs: There will be no average changes communicated,.

Impact of Changes on Your Bill

Several factors influence the evolution of your electricity bill:

• Supply cost: The TRVE are impacted by a decrease in the cost of energy supply (-4.22% excluding tax),.
• Energy Savings Certificates (CEE): An increase in costs related to CEE (+2.09% excluding tax) is expected,.
• Capacity guarantees: A decrease in the cost of capacity guarantees (-0.79% excluding tax) is also to be noted,.
• Adjustments: An increase in adjustments is expected (+2.81% excluding tax),.
• TURPE: The transmission and distribution component (TURPE) will remain unchanged,.

Understanding the Key Components of Your Bill

Deciphering your electricity bill is the first step to optimizing your energy expenses. Here are the main components to know:

• Cost of electricity supply: It represents the price of the energy you consume.
• Transmission and distribution costs: It covers the costs of transporting and distributing electricity to your business.

Taxes and Contributions

Several taxes and contributions apply to your electricity consumption,,:

• Excise duty on electricity: Formerly CSPE/TICFE, it is adjusted according to inflation,,. For example, the rate will increase from 2.998 c€/kWh to 3.085 c€/kWh for households and small businesses,,. Some companies may be eligible for reduced rates or exemptions under certain conditions,,.
• Tariff Contribution for Transmission (CTA): It contributes to the financing of the retirement system for employees in the electricity and gas industries. Note that the Contribution to the Public Electricity Service (CTA) will decrease from 21.93% to 15%.
• Value Added Tax (VAT) : It applies to the total cost of your bill (supply, transmission and distribution, and other taxes) at a rate of 20%,,.

Tariff Options

Your tariff option directly influences the price of your electricity:

• Base Option: The price per kWh is constant, regardless of the time of day.
• Peak Hours/Off-Peak Hours Option: The price per kWh varies depending on the time of day. Off-peak hours, usually at night, are cheaper.

For the EDF Blue Tariff in December 2025, the prices are:

• Base Option: 0.1616 €/kWh excluding VAT
• Peak Hours: 0.167 €/kWh excluding VAT
• Off-Peak Hours: 0.1409 €/kWh excluding VAT

Choosing the Right Supplier and the Right Type of Offer

Since the opening of the energy market in 2007, companies have had the opportunity to choose their electricity supplier. This freedom allows you to compare offers and find the one that best suits your needs.

Indexed Price Offers vs. Fixed Price Offers

• Indexed price offers: The price per kWh is indexed to a market index (for example, the wholesale price of electricity). These offers can be advantageous in periods of falling prices, but they are also riskier in the event of an increase.
• Fixed price offers: The price per kWh is fixed for the duration of the contract. These offers provide better visibility on your energy expenses, but they may be less competitive in periods of falling prices.

Transparency of Offers

The CRE has implemented guidelines to improve the transparency of electricity and natural gas offers. These guidelines, already in effect for residential consumers, will be extended to small businesses and associations by the summer of 2025. The objective is to provide you with clear and complete information to help you make an informed decision.

How to Compare Business Electricity Offers

To effectively compare electricity offers, follow these tips:

• Analyze the price per kWh (excluding VAT): This is the main indicator of an offer's competitiveness. The cheapest supplier in December 2025 is MET France with a rate of 0.1201 €/kWh excluding VAT in the Base option.
• Consider subscription fees: Some suppliers charge monthly subscription fees, which can impact the total cost of your bill.
• Check the contractual conditions: Pay attention to the duration of the contract, the termination conditions, and any price revision clauses.
• Eligibility for reduced rates: Inquire about your eligibility for reduced rates or tax exemptions,,.

Capacity Mechanism and Market Prices: What Impact?

Understanding how the electricity market works and the mechanisms that influence it is essential to anticipate changes in your bills.

The Capacity Mechanism

Introduced in France since January 1, 2017, the capacity mechanism aims to guarantee the security of electricity supply during peak consumption periods. It encourages suppliers to have sufficient production capacity to meet demand by allocating them "capacity certificates". These certificates can be bought and sold on a specific market, which influences the price of electricity.

Monitoring Wholesale Electricity Prices

Wholesale electricity prices, and in particular spot prices (short-term electricity prices), are important indicators to follow. On January 4, 2026, the wholesale price of electricity reaches 124 €/MWh, the spot price is 94 €/MWh, with a forecast increase to 128 €/MWh for the next day. The analysis reveals a decrease of 7.8% compared to the previous year, but a significant increase of 34.8% compared to December 2025. These fluctuations can impact indexed price offers.

The New Market Organization in 2026: End of ARENH and Nuclear Payments

The year 2026 marks a turning point in the organization of the electricity market in France, with the end of the Regulated Access to Historic Nuclear Electricity (ARENH) scheme,.

The Universal Nuclear Payment (VNU)

To replace ARENH, a new mechanism called "universal nuclear payment" (VNU) will be implemented,. The objective of the VNU is to stabilize electricity prices by guaranteeing a stable remuneration for nuclear electricity producers.

Potential Consequences for Businesses

According to the data in effect, the exact consequences of the VNU for businesses are still under discussion. It is crucial to follow government announcements and expert analyses to anticipate the impact on your electricity bills.

Tips for Optimizing Your Consumption and Reducing Your Bill

Beyond choosing your supplier and your type of offer, there are many actions you can take to reduce your electricity consumption and optimize your bill.

• Conduct an energy audit: An energy audit helps identify the main consumption items of your company and implement corrective actions.
• Adopt energy-efficient practices: Educate your employees about best practices (turning off lights when leaving a room, unplugging devices on standby, etc.).
• Invest in less energy-consuming equipment: Replace your old equipment with more efficient models (LED lighting, class A appliances, etc.).

Frequently Asked Questions

How do I know if I am eligible for reduced electricity rates?

Eligibility for reduced rates or tax exemptions depends on several factors, including the size of your business, your sector of activity, and your level of energy consumption. Contact your electricity supplier directly or consult the CRE website for detailed information on eligibility criteria and procedures.

What is the difference between subscribed power and called power?

The subscribed power is the maximum power you can draw from the electricity grid. It is defined in your contract with your electricity supplier. The called power is the power you actually consume at a given moment. It is important to properly size your subscribed power to avoid paying too high a subscription fee compared to your actual needs.

How can I track my electricity consumption in real time?

Many electricity suppliers offer real-time consumption tracking tools, accessible via their website or mobile application. These tools allow you to visualize your electricity consumption by day, week, or month, and identify the most significant consumption items. Some smart meters, such as Linky, also allow you to track your consumption in real time.

What should I do in the event of a dispute with my electricity supplier?

In the event of a dispute with your electricity supplier, you can first try to resolve the problem amicably by contacting their customer service. If you are not satisfied, you can contact the energy ombudsman, an independent body whose mission is to settle disputes between consumers and energy suppliers. You can also contact a consumer association for help and advice.

How can I anticipate future increases in electricity tariffs?

Anticipating increases in electricity tariffs is a challenge, but there are strategies to prepare for it. Regularly monitor energy market news and CRE announcements. Diversify your energy sources by investing in self-consumption solutions (solar panels, for example). Optimize your energy consumption by implementing energy-efficient practices.

Practical Numerical Examples

Case 1: SME switching from Base option to Peak/Off-Peak Hours

An SME consumes 20,000 kWh per year with a Base option. Its annual cost is 20,000 kWh * €0.1616/kWh = €3232 excluding VAT. By switching to the Peak/Off-Peak Hours option, it manages to shift 40% of its consumption (8000 kWh) to off-peak hours. Its new cost is (12,000 kWh * €0.167/kWh) + (8000 kWh * €0.1409/kWh) = €2004 + €1127.2 = €3131.2 excluding VAT. The annual saving is €3232 - €3131.2 = €100.8 excluding VAT. Although modest, this saving illustrates the potential of changing tariff options.

Case 2: Impact of the increase in CEE

A company consumes 100,000 kWh per year. The increase in costs related to CEE is 2.09% excluding VAT. This translates into an increase of 100,000 kWh * 0.0209 * Price_kWh. If the price of kWh is €0.15, the increase is 100,000 * 0.0209 * 0.15 = €313.5 excluding VAT. This increase, although small as a percentage, can represent a significant sum for large companies.

Case 3: Investment in LED lighting

A company replaces 50 traditional 100W bulbs with 15W LED bulbs. The bulbs are on 8 hours a day, 5 days a week. The annual consumption of the old bulbs is 50 * 0.1 kW * 8 hours * 5 days * 52 weeks = 10400 kWh. The annual consumption of the new bulbs is 50 * 0.015 kW * 8 hours * 5 days * 52 weeks = 1560 kWh. The annual saving is 10400 kWh - 1560 kWh = 8840 kWh. At a price of €0.1616/kWh, the financial saving is 8840 kWh * €0.1616/kWh = €1428.54 excluding VAT. The initial investment is quickly amortized.

Best Practices for Energy Management

• Implement an energy management system (ISO 50001): This international standard helps companies continuously improve their energy performance.
• Train your employees in eco-responsibility: Raise their awareness of energy issues and good practices to adopt on a daily basis.
• Perform regular maintenance on your equipment: Poorly maintained equipment consumes more energy.
• Use building management systems (BMS): These systems allow you to control and optimize the energy consumption of your buildings.
• Actively negotiate your electricity contracts: Compare offers from different suppliers and don't hesitate to renegotiate your contract regularly.

Mistakes to Avoid

• Neglecting the energy audit: An energy audit is essential to identify sources of energy waste.
• Relying solely on the price per kWh to choose your supplier: It is important to take into account all costs and contractual conditions.
• Not tracking your energy consumption: Regular monitoring of your consumption allows you to identify anomalies and implement corrective actions.
• Not involving your employees in the energy efficiency approach: The involvement of your employees is essential for the success of your energy optimization program.
• Underestimating the impact of taxes and contributions: Taxes and contributions represent a significant portion of your electricity bill.

Impact of Teleworking on Companies' Electricity Bills

The rise of teleworking has changed the energy consumption habits of companies. While the overall consumption of offices may decrease, some of this consumption is transferred to employees' homes. Companies can implement measures to compensate for this impact, such as:

• Provide low-energy equipment to teleworking employees: Laptops, LED screens, etc.
• Implement financial incentives to encourage employees to adopt energy-efficient practices at home: Bonuses, partial reimbursement of electricity bills, etc.
• Organize training sessions on energy efficiency for teleworking employees: Practical tips, best practices, etc.

The Role of Renewable Energies in Reducing Electricity Bills

Investing in renewable energies can allow companies to reduce their dependence on the electricity grid and lower their electricity bills. The most common solutions are:

• The installation of photovoltaic solar panels: The electricity produced can be self-consumed or resold on the grid.
• The installation of heat pumps: Heat pumps allow you to heat or cool buildings efficiently and economically.
• Participation in joint renewable energy projects: Companies can pool together to invest in renewable energy projects and share the benefits.

In summary

In 2026, the professional electricity bill is evolving: excise duty increase, gradual end of the tariff shield and the new VNU mechanism. Understanding these changes — regulated tariffs, taxes, pricing options and capacity mechanism — is essential to anticipate increases and choose the right offer.

At Unisave, we decode your bills and help you identify the most suitable offer for your profile.

In February 2026, the Regulated Electricity Sale Tariffs (TRVE) experienced a slight decrease. This average decrease of 0.83% affects approximately 19.75 million customers [1, 22] and translates into savings of approximately €9 including VAT per year for many of them. This decrease is mainly due to the reduction in supply costs and changes in EDF's marketing costs.

It is important to note that this decrease is not uniform for all tariff types. The non-residential Blue Tariff experienced a decrease of 1.29% excluding VAT, while the Yellow and Green Tariffs did not experience any average change. Furthermore, the old Green Tariff was abolished on February 1, 2026, with the possibility of retaining it under certain conditions.

Real Impact of the Tariff Decrease: Details and Nuances

The tariff decrease translates concretely into a decrease of €1.99 including VAT/MWh, representing approximately €9 including VAT per year for consumers with a subscribed power of less than 36 kVA. However, it is crucial to note that this decrease is mitigated by the increase in taxation applicable to the TRVE.

It is also essential to understand the distinction between the different tariffs (Blue, Yellow, Green) because the impact of these changes varies depending on the tariff applied. The abolition of the Green Tariff, for example, has specific implications for companies that previously benefited from this tariff.

The End of the Tariff Shield: An Announced Shock for 2026?

The tariff shield played a crucial role in limiting TRVE increases to 4% in 2022 and 15% in 2023. This mechanism protected consumers from significant fluctuations in the energy market. The total cost of this shield is estimated at approximately €72 billion between 2022 and 2024, representing 2.6% of GDP.

However, the tariff shield is scheduled to end, and this could lead to significant increases in TRVE. This prospect raises concerns about the impact on household purchasing power and business competitiveness.

Consequences of the Disappearance of the Shield: Price Increases and Inflation

The gradual withdrawal of the tariff shield has already led to an 18.4% increase in the average electricity price for households in 2024, reaching €280/MWh. This increase has a direct impact on household budgets and business profitability.

In addition, the withdrawal of the tariff shield is expected to lead to a 1.0 point increase in inflation in 2024 and a 0.8 point increase in 2025. This increase in inflation could have repercussions on the entire economy, affecting the prices of goods and services and reducing consumer purchasing power.

Alternatives and Perspectives: How to Anticipate Price Increases. This is precisely what we do at Unisave for our clients?

The Autorité de la concurrence (Competition Authority) expresses doubts about the effectiveness of the new mechanisms put in place to mitigate the impact of the end of the tariff shield, highlighting a potential cost of at least €2 billion per year linked to the capacity mechanism. In this context, it is essential for consumers and businesses to explore alternatives to control their energy costs.

An interesting option is to explore fixed-price offers, which allow you to lock in the price of electricity for a specified period. For example, Gaz de Bordeaux's NovaFixe Élec offer would save approximately €164 per year compared to EDF's regulated tariff, with an annual bill of €1166 for a consumption of 6000 kWh.

It is also important to monitor the price trends of dynamic pricing offers, which can offer savings opportunities by adapting consumption to periods of low demand. For example, on February 10, 2026, the average price of electricity for dynamic pricing offers was €0.1026/kWh, down 24.7% compared to the previous day, with a forecast of €0.0523/kWh for the following day, a reduction of 49%.

EDF and CRE Initiatives: Towards a More Stable Energy System?

EDF published the PPE3 (Multi-year Energy Program) on February 12, 2026, committing in particular to building six new EPR2 nuclear reactors. These investments in nuclear energy aim to ensure security of supply and stabilize electricity prices in the long term. According to current data, these new reactors are expected to come into service progressively from 2035.

The CRE (Commission de Régulation de l'Énergie - Energy Regulatory Commission) launched a public consultation in February 2025 concerning RTE's (Réseau de Transport d'Électricité - Electricity Transmission Network) SDDR (Schéma Décennal de Développement du Réseau - Ten-Year Network Development Plan). This consultation aims to gather feedback from industry stakeholders on electricity grid development projects for the next ten years. The CRE has also published a report on smart grids, highlighting the progress made and the challenges to be met in optimizing electricity management.

How to Optimize Your Business Electricity Consumption?

The end of the tariff shield makes optimizing electricity consumption more crucial than ever. Here are some concrete ways to reduce your bill and improve your energy efficiency:

Energy Audit: The Essential First Step

Conducting a comprehensive energy audit of your facilities is the first step to identify weaknesses and potential savings. This audit should take into account:

• Building insulation: Verification of the insulation of walls, roofs, windows and doors.
• The heating, ventilation and air conditioning (HVAC) system: Analysis of the system's efficiency and identification of leaks or energy losses.
• Lighting: Replacing old lighting with low-energy LEDs and installing presence detectors.
• Electrical equipment: Analysis of the consumption of machines, computers, servers and other electrical appliances.
• Production processes: Optimizing processes to reduce energy consumption.

Invest in More Efficient Equipment

Replacing old and energy-intensive equipment with newer, more efficient models is a cost-effective investment in the long term. Consider in particular:

• Replacing old computers and servers: New models consume much less energy.
• Installing variable speed drives on motors: Allows the motor speed to be adapted to actual needs and avoids energy losses.
• Using energy management systems (EMS): These systems allow you to monitor and control energy consumption in real time and identify anomalies.
• Opting for heat pumps: For heating and air conditioning, heat pumps are much more efficient than traditional systems.

Adopt Eco-Responsible Practices

Optimizing electricity consumption also involves adopting eco-responsible practices within the company:

• Raise employee awareness: Inform them about the challenges of energy efficiency and encourage them to adopt responsible behaviors (turn off lights when leaving a room, unplug appliances on standby, etc.).
• Implement clear instructions: Define rules for the use of electrical equipment and ensure that they are respected.
• Program the automatic shutdown of equipment: Use timers or energy management systems to automatically turn off equipment outside of working hours.
• Promote teleworking: Reduces energy consumption related to employee travel and the use of company premises.

Practical Example: Lighting Renovation of a Warehouse

Let's take the example of a 1000 m² warehouse lit by 400W high-pressure sodium (HPS) lamps. These lamps consume a lot of energy and have a limited lifespan. By replacing these lamps with 150W LEDs, the company can achieve the following savings:

• Initial consumption (HPS): 100 lamps x 400W = 40 kW
• Consumption after renovation (LED): 100 lamps x 150W = 15 kW
• Consumption saving: 40 kW - 15 kW = 25 kW

If the warehouse is lit for 12 hours a day, 300 days a year, the annual energy saving is:

25 kW x 12 hours/day x 300 days/year = 90,000 kWh

At the average electricity price of €0.25/kWh, the annual financial saving is:

90,000 kWh x €0.25/kWh = €22,500

In addition, LEDs have a much longer lifespan than HPS lamps, which reduces maintenance and replacement costs.

Alternative Electricity Offers: Comparison and Advice

Faced with the increase in TRVE, it is essential to evaluate the different electricity offers available on the market. Here is a comparison of the main options:

Fixed-Price Offers

These offers allow you to block the price of electricity for a fixed period (usually 1 to 3 years). They offer visibility on energy costs and protect against market fluctuations. However, they may be less competitive if market prices fall.

Indexed-Price Offers

These offers follow the evolution of electricity market prices. They can be more advantageous if prices fall, but they are also riskier in the event of an increase. It is important to understand the reference index and the terms of price revisions.

Dynamic Pricing Offers

These offers allow you to adapt your consumption to periods of low demand, when electricity prices are lower. They require careful monitoring of prices and a certain flexibility in consumption. They are particularly suitable for companies that can shift their consumption (for example, by scheduling the operation of certain machines during off-peak hours).

Comparative Table of Electricity Offers

Tips for Choosing the Right Offer

• Assess your consumption profile: Analyze your consumption habits and identify the periods when you consume the most electricity.
• Compare offers: Use online comparators to compare prices and conditions of different offers.
• Read contracts carefully: Check the clauses relating to price revisions, penalties in the event of early termination and included services.
• Don't hesitate to negotiate: Electricity suppliers are often willing to negotiate prices and contract terms, especially for businesses.
• Get support: If you have difficulty choosing the right offer, get support from an energy broker.

Frequently Asked Questions

How will the end of the tariff shield affect my electricity bill?

The end of the tariff shield will likely lead to an increase in your electricity bill, as prices will no longer be artificially kept low. The extent of the increase will depend on your type of contract (TRVE or market offer) and the evolution of energy prices.

What are the alternatives to TRVE for my business?

Several alternatives exist, including fixed-price offers, indexed-price offers and dynamic pricing offers. It is important to compare these offers and choose the one that best suits your consumption profile and your needs.

How can I reduce my business electricity consumption?

You can reduce your electricity consumption by conducting an energy audit, investing in more efficient equipment, adopting eco-responsible practices and raising employee awareness.

What is an energy audit and how can I carry one out?

An energy audit is a comprehensive analysis of your energy consumption. It identifies weaknesses and potential savings. You can have an energy audit carried out by a specialized design office.

What are the advantages of LEDs compared to older lighting systems?

LEDs consume much less energy than older lighting systems (incandescent lamps, halogens, etc.) and have a much longer lifespan. They reduce electricity and maintenance costs.

How can I benefit from financial aid to improve my business's energy efficiency?

Several financial aids are available for companies wishing to improve their energy efficiency, including energy saving certificates (CEE), ADEME aid and tax credits. Contact the relevant organizations to find out about the eligibility conditions.

What is dynamic electricity pricing?

How can I track the evolution of electricity prices?

You can track the evolution of electricity prices by consulting the websites of energy suppliers, online comparators and regulatory bodies (CRE, etc.).

Mistakes to Avoid for Optimal Electricity Management

Good electricity management in a company is not limited to choosing the right supplier. It is crucial to avoid certain common mistakes that can lead to unnecessary additional costs:

Neglecting Equipment Standby

Leaving computers, printers and other devices on standby consumes unnecessary energy. Even on standby, these devices continue to consume electricity. It is best to turn them off completely when they are not in use.

Underestimating the Impact of Lighting

Lighting represents a significant portion of electricity consumption, especially in large spaces. Using energy-intensive lamps or leaving the lights on unnecessarily can lead to significant additional costs.

Ignoring Energy Leaks

Energy leaks can come from poor insulation, poorly insulated windows, doors that do not close properly or defective heating and air conditioning systems. These leaks can lead to significant energy loss and increase your electricity bill.

Not Adapting the Subscribed Power

The subscribed power is the maximum power that you can draw from the electricity grid. If your subscribed power is too high compared to your actual needs, you pay a more expensive subscription unnecessarily. Conversely, if your subscribed power is too low, you risk tripping the circuit breaker frequently.

Neglecting Equipment Maintenance

Poorly maintained equipment consumes more energy than equipment in good working order. For example, a clogged air conditioning system will consume more electricity to produce the same amount of cold. It is important to regularly maintain equipment to optimize its energy efficiency.

Key takeaways

The end of the tariff shield in 2026 exposes businesses to wholesale market volatility. The regulated tariff decrease in February 2026 is misleading: it reflects current market conditions, but without a safety net if prices rise again. Businesses must plan ahead by comparing offers, auditing consumption and adjusting subscribed power.

At Unisave, we analyse the concrete impact on your bills and help you secure your energy costs.

1. Energy supply

This is the portion related to the electricity you actually consume. It is billed by your supplier (EDF, Engie, TotalEnergies, etc.) and consists of two elements:

• Subscription (fixed charge): a monthly amount based on the power level you have subscribed, expressed in kVA. The higher your subscribed power, the more expensive the subscription.
• Consumption (variable charge): the price per kWh multiplied by your actual consumption. This price varies depending on your tariff option (flat rate, peak/off-peak hours, etc.).

2. Network charges (TURPE)

TURPE (Tarif d'Utilisation des Reseaux Publics d'Electricite) covers the costs of accessing and using the electricity grid. It remunerates the grid operators — Enedis for distribution and RTE for transmission — for delivering electricity to your meter. This tariff is an essential element of your bill and is independent of your energy supplier.

TURPE is regulated and its calculation takes into account different components related to management, metering and subscribed power. It is designed to ensure the maintenance, development and modernization of the electricity grid.

3. Taxes and levies

A significant portion of your electricity bill consists of various taxes and levies, which are collected by energy suppliers and remitted to the State. These taxes can have a significant impact on the total cost of your bill.

Electricity excise duty (formerly TICFE / CSPE)

The electricity excise duty, formerly known as TICFE (Taxe Intérieure sur la Consommation Finale d'Électricité) and CSPE (Contribution au Service Public de l'Électricité), is a tax proportional to the quantity of electricity consumed. Its amount is set annually by the finance law.

Certain businesses may be eligible for reduced rates or exemptions, under certain conditions and depending on their activity. Eligible businesses include, but are not limited to:

• Electro-intensive businesses, meeting criteria defined in the customs code.
• Specific industrial processes, such as electrolysis or chemical reduction.
• Electricity used for rail transport.

CTA (Contribution Tarifaire d'Acheminement)

The Contribution Tarifaire d'Acheminement (CTA) is calculated on the fixed portion of the TURPE (Tarif d'Utilisation des Réseaux Publics d'Électricité). It is intended to finance specific rights relating to the old-age insurance of personnel in the electricity and gas industries. Its rate is set by ministerial decree.

VAT

The Taxe sur la Valeur Ajoutée (TVA) applies to almost all components of your electricity bill, but at different rates:

• 5.5% VAT: This reduced rate generally applies to the subscription and the CTA, for sites with a subscribed power of 36 kVA or less.
• 20% VAT: The standard rate applies to consumption, variable TURPE, electricity excise duty, as well as to the entire bill for sites with a subscribed power greater than 36 kVA.

4. What to check first on your bill

Here are the points most frequently associated with errors or unnecessary costs:

1. Subscribed power: is it correctly sized relative to your actual power demand? An oversized subscription inflates both the fixed charge and the TURPE fixed component.
2. Tariff option: flat rate, peak/off-peak, or specific pricing — does your option match your consumption profile?
3. Meter readings: are they actual (read by Enedis or remotely via Linky) or estimated? Estimated readings left uncorrected for months can generate significant discrepancies.
4. TURPE version: does the applied tariff correspond to the current schedule published by the CRE?
5. Taxes: if your activity qualifies you for a reduced excise rate, is the reduction actually being applied?
6. Contract vs. bill alignment: do the unit prices on your bill match the contractual terms you signed?

Practical examples of calculation and optimization

Case 1: Optimizing the subscribed power for a manufacturing workshop

A manufacturing workshop has a subscribed power of 100 kVA. Analysis of consumption data over the last 12 months reveals that the maximum power actually drawn never exceeded 75 kVA. The monthly subscription for 100 kVA is €500, while for 80 kVA it would be €420. By reducing the subscribed power to 80 kVA, the workshop would save €80 per month, or €960 per year, on the subscription alone. In addition, the fixed withdrawal component of the TURPE would also be reduced, generating additional savings. It is crucial to verify that this power reduction will not cause nuisance tripping in the event of exceptional consumption peaks. A simulation with historical data is recommended.

Case 2: Impact of choosing the Peak Hours / Off-Peak Hours tariff option for a refrigerated warehouse

A refrigerated warehouse operates 24/7. Initially, it was on the Base tariff option. An analysis of its consumption shows that 60% of its consumption takes place during off-peak hours (usually at night and on weekends). The price per kWh during peak hours is €0.20, while during off-peak hours it is €0.12. By switching to the Peak Hours / Off-Peak Hours option, the warehouse could save:

• Without optimization: 60% of consumption at €0.12 instead of €0.20, i.e. a saving of €0.08 per kWh on 60% of total consumption.
• With optimization: By scheduling the defrosting of installations during off-peak hours, the warehouse could increase its consumption during off-peak hours to 70%, thus increasing savings.

It is important to note that the Peak Hours / Off-Peak Hours option often involves a slightly more expensive subscription. The break-even point must therefore be calculated according to the specific consumption of the company.

Case 3: Renegotiating the energy supply contract

An SME has a fixed-price electricity supply contract of €0.18/kWh. By consulting market offers, it notes that spot prices are currently around €0.15/kWh. It can then renegotiate its contract with its current supplier or prospect with other suppliers to obtain a more competitive price. A saving of €0.03/kWh on an annual consumption of 500,000 kWh represents a potential saving of €15,000 per year. It is crucial to carefully analyze the general terms and conditions of sale, in particular the price revision clauses and penalties in the event of early termination.

Tips for optimizing your electricity bill

Energy audit: The first step towards optimization

Carrying out an energy audit of your company is the first crucial step in understanding your consumption and identifying areas for improvement. This audit allows you to analyze in detail your consumption by item (lighting, heating, air conditioning, industrial equipment, etc.) and to detect waste and inefficiencies. The audit results in a concrete and quantified action plan, with personalized recommendations to reduce your electricity bill.

Active consumption management

The implementation of an active consumption management system (real-time monitoring of consumption, alerts in the event of exceeding thresholds, remote control of equipment) allows you to better control your consumption and react quickly in the event of an anomaly. Software solutions exist to collect and analyze consumption data, identify trends and areas for improvement. The installation of smart meters (Linky) facilitates data collection and consumption monitoring.

Investment in high-performance equipment

Replacing old and energy-intensive equipment with more efficient equipment (LED lighting, variable speed drives on motors, efficient heating and air conditioning systems, etc.) is a worthwhile long-term investment. The energy savings achieved quickly offset the cost of acquiring new equipment. Many financial aids (energy saving certificates, subsidies, tax credits) are available to encourage companies to invest in high-performance equipment.

Training and awareness of staff

Training and raising staff awareness of energy efficiency issues is essential to anchor good practices and encourage responsible behavior. Simple actions (turning off the lights when leaving a room, unplugging devices on standby, optimizing the setting of heating and air conditioning, etc.) can generate significant savings. The implementation of an internal challenge with consumption reduction objectives can stimulate staff engagement.

Anticipating developments in the energy market

The energy market is constantly evolving, with volatile prices and regulations that change regularly. It is important to stay informed of market trends and new technologies to anticipate risks and seize opportunities. Diversifying sources of supply (group purchasing, renewable energy, self-consumption) can reduce dependence on traditional suppliers and limit the impact of price fluctuations.

Errors to avoid in managing your electricity bill

Neglecting regular monitoring of your consumption

Regular monitoring of your consumption is essential to quickly detect anomalies (leaks, overconsumption, billing errors) and take the necessary corrective measures. Failure to monitor can lead to significant additional costs and compromise your optimization efforts.

Underestimating the impact of regulated tariffs

Even if you have a market price contract, regulated tariffs can have an indirect impact on your bill, in particular via the TURPE. It is important to understand how these tariffs are calculated and to monitor their evolution to anticipate any increases.

Not checking meter readings

Erroneous meter readings (estimated or poorly read) can lead to significant billing errors. It is important to regularly check the meter readings and report any anomalies to your supplier.

Ignoring available financial aid

Many financial aids (energy saving certificates, subsidies, tax credits) are available to encourage companies to invest in energy efficiency. Ignoring this aid means depriving yourself of opportunities to reduce your costs and improve your energy performance.

Focusing only on the price per kWh

The price per kWh is only one element of your electricity bill. It is important to take into account all the components (subscription, TURPE, taxes) to have a global view of your costs and identify the most relevant areas for optimization.

Frequently Asked Questions

How to dispute an electricity bill?

If you notice an error on your electricity bill, the first step is to contact your supplier by telephone or in writing (registered letter with acknowledgment of receipt) to report the error and ask them to correct it. Attach the necessary supporting documents to your complaint (meter readings, previous invoices, etc.). If your supplier does not respond or if their response does not satisfy you, you can contact the energy ombudsman, an independent body that can help you resolve the dispute.

What is the floor area ratio (FAR) and how does it impact my bill?

The floor area ratio (FAR) does not directly impact your electricity bill. The FAR is a town planning rule that defines the density of construction allowed on a plot of land. It can indirectly influence your electricity consumption if your activity is linked to the built area (for example, a larger warehouse will require more lighting and air conditioning).

How to choose the right electricity supplier for my company?

Choosing the right electricity supplier depends on several factors, including your consumption profile, your budget, your green energy objectives, and your risk appetite. It is important to compare the offers of different suppliers taking into account the price per kWh, the price of the subscription, the general terms and conditions of sale, and the quality of customer service. Do not hesitate to call on an energy broker to help you compare offers and negotiate the best rates.

What are the regulatory obligations regarding energy efficiency for companies?

Companies are subject to several regulatory obligations regarding energy efficiency, including the mandatory energy audit for large companies, the tertiary decree which imposes energy consumption reduction objectives for tertiary buildings, and the energy saving certificates (CEE) which encourage companies to carry out work to improve energy efficiency.

How to benefit from a reduced rate of excise duty on electricity?

To benefit from a reduced rate of excise duty on electricity, your company must meet certain eligibility criteria, in particular being an electro-intensive company or carrying out a specific activity (electrolysis, chemical reduction, rail transport). You must submit a request for reimbursement or exemption to the customs administration, providing the necessary supporting documents.

Case study: Reducing the electricity bill of a food processing plant

A food processing plant consumed 1,200,000 kWh per year, with an annual bill of €216,000. After a complete energy audit, several actions were put in place:

• Replacement of lighting with LEDs: saving 15,000 kWh per year.
• Optimization of the industrial refrigeration system: saving 60,000 kWh per year.
• Installation of variable speed drives on pump motors: saving 25,000 kWh per year.
• Renegotiation of the electricity supply contract: reduction in the price per kWh from €0.18 to €0.16.

Thanks to these actions, the plant reduced its annual consumption by 100,000 kWh and its annual bill by €32,000, a saving of 15%. The total investment was €80,000, with a return on investment of 2.5 years.

Self-consumption: a solution to reduce your dependence on the grid

Self-consumption consists of producing and consuming your own electricity, generally from photovoltaic solar panels. This solution allows you to reduce your dependence on the grid, control your energy costs, and contribute to the energy transition. Self-consumption can be total (you consume all the electricity you produce) or partial (you consume part of the electricity you produce and inject the surplus into the grid). Financial aid (self-consumption bonus, tax credit) is available to encourage companies to invest in self-consumption.

Comparison of electricity offers for professionals

In summary

Your professional electricity bill is made up of three main components: supply (the price per kWh), network charges (TURPE) and taxes (excise duty, CTA, VAT). Understanding these components is the first step to spotting anomalies and optimising your costs.

At Unisave, we audit every line of your bills to identify discrepancies and savings opportunities.

The year 2026 marks a turning point for the excise duty on electricity in France, with direct implications for businesses. This evolution, stemming from the stabilization of rates and the simplification of administrative procedures, deserves particular attention, especially for electro-intensive companies and sectors exposed to international competition. The importance of the certificate to benefit from reduced rates is a crucial point to remember.

Stabilization of standard rates: what figures to remember?

The standard rates of the excise duty on electricity have been set at €26.58/MWh for SMEs (with a power between 36 and 250 kVA) and high-power companies (more than 250 kVA), excluding non-interconnected zones (ZNI). An increase is applicable for ZNIs, bringing the rate to €26.58/MWh in these territories. It is important to note that these rates are subject to annual review on February 1st.

Reform of exemptions and reduced rates: the details

The reform of the excise duty on electricity in 2026 brings a significant simplification in the number of reduced rates, from 7 to 4. This simplification is accompanied by new thresholds for electro-intensive companies, with a reduced rate of €0.5/MWh, and for electro-sensitive companies, with a reduced rate of €3/MWh.

Furthermore, the list of sectors exposed to international competition, which may be eligible for exemptions or reduced rates, is subject to review. An order must be published before the end of 2025 to specify this list.

Who is affected by the reduced rates?

The reduced rates of the excise duty on electricity are intended for certain categories of companies, including:

• Electro-intensive companies, i.e. those whose electricity consumption represents more than 13.5% of their added value.
• Sectors exposed to international competition, such as metallurgy and chemicals.
• Large electricity consumers and sensitive profiles.

How is the excise duty applied in practice?

The excise duty on electricity is integrated directly into the electricity bill of companies, appearing as a price per kWh. Electricity suppliers directly apply the excise duty rates upon presentation of a certificate of eligibility for reduced rates by the company. In some cases, it is also possible to request an administrative refund of the excise duty.

The importance of the certificate for companies

Providing a certificate is essential to benefit from the reduced rates of the excise duty on electricity. It is therefore imperative for companies to verify their eligibility with the tax authorities and provide the necessary supporting documents. Reduced rates are assessed on a case-by-case basis, depending on the consumption profile and activity of the company.

Impacts and practical advice for companies

At Unisave, we systematically check the excise duty rates applied on our clients' bills. It is crucial for companies to be vigilant regarding the correct application of excise duty rates per period, in order to avoid billing errors. It is also important to check eligibility for derogation schemes, depending on your consumption profile and sector of activity.

For reliable and up-to-date information, it is recommended to consult official sources, such as the Bulletin Officiel des Finances Publiques (BOFiP) and the Légifrance website.

Anticipate changes to optimize your bill

To anticipate changes related to the excise duty on electricity in 2026 and optimize your energy bill, it is advisable to:

• Analyze your consumption profile, distinguishing between the different categories (C4/C1-C3).
• Prepare for the changes that will occur after the end of the tariff shield.
• Contact your electricity supplier to obtain personalized information on your situation and the steps to follow.

By anticipating these changes and informing yourself from official sources and your supplier, you will be able to control the impact of the excise duty on electricity on your budget and optimize your energy bill.

Key takeaways

The excise duty on electricity in 2026 stabilises around €26.58/MWh for businesses, with reduced rates maintained for electro-intensive profiles (€0.5/MWh) and electro-sensitive ones (€3/MWh). The essential point: obtain and submit the eligibility certificate to your supplier, otherwise the standard rate applies by default.

At Unisave, we check that the correct excise duty rate is applied on your bills and assist you with the certification process.

Here are the five errors we detect most frequently during our audits.

How to protect yourself

A few best practices to limit the risk of errors:

1. Centralise bill management: consolidate all bills in a tracking spreadsheet to spot amount or volume anomalies.
2. Check meter readings regularly: ensure bills are based on actual readings, especially for sites without smart meters.
3. Review subscribed power annually: compare subscribed power to actual power demand over the past 12 months.
4. Anticipate contract deadlines: note end dates and notice periods in a calendar.
5. Have your portfolio audited: a specialised external review can detect errors that internal teams may overlook.

The two main contract families

Fixed-price contracts in detail

With a fixed-price contract, the supplier commits to a constant price per kWh for the entire contract duration. This price typically includes the energy supply and, in some offers, part of the network charges.

When to choose fixed pricing?

• Need for budget predictability: the energy budget is known in advance, making financial forecasting easier.
• Markets at historically low levels: locking in a low price protects against future increases.
• Low risk appetite: the business prefers security over opportunity.
• Committed selling prices: if your business involves fixed quotes or tariffs for your clients, a fixed energy cost protects your margins.

Indexed-price contracts in detail

Indexed pricing follows the fluctuations of a wholesale market reference index. For electricity in France, the most common indices are:

• EEX (European Energy Exchange): the futures market, with quotations for future periods (month, quarter, year).
• EPEX Spot: the spot market (day-ahead or hourly prices). More volatile, but reflects the real market price at a given moment.

For natural gas, references include the PEG (Point d'Echange de Gaz) and the TTF (Title Transfer Facility, the European benchmark).

When to choose indexed pricing?

• Markets at elevated levels: during high-price periods, an indexed contract allows you to benefit from a potential decline.
• Ability to absorb volatility: the business has sufficient cash flow to manage monthly fluctuations.
• Active market monitoring: the business (or its advisor) regularly tracks prices and can consider locking in prices later ("clicking" to a fixed price).

Comparison table

Hybrid formulas

Between fully fixed and fully indexed, intermediate formulas exist:

• Fixed price with "tunnel" clause: the price is fixed but can be revised up or down within a predetermined range.
• Indexed price with cap: the price follows the market but cannot exceed a defined ceiling. This protection comes at a cost (premium).
• Progressive fixing (clicks): the contract is indexed, but the business can "fix" volume tranches at a given price over time, to smooth out risk.

4 questions to ask before choosing

1. What is my risk tolerance? During our advisory work at Unisave, this is the first question we ask our clients. If a 20% increase in the energy bill would strain your cash flow or margins, fixed pricing is more prudent.
2. Do I have the resources to monitor markets? An indexed contract requires regular market watching. Without monitoring, you are subject to fluctuations without being able to react. It is all the more important to read your bill carefully to check the prices applied.
3. What is the current market context? Locking in a price when markets are low is strategically sound. Conversely, committing to a fixed price at the top of the cycle can be costly.
4. What is the optimal duration? The longer the contract, the higher the risk premium built into the fixed price by the supplier. A 12-month contract generally offers better conditions than a 36-month commitment.

Conclusion

There is no universal answer: the best contract depends on your consumption profile, risk tolerance, and market conditions. The key is to make an informed choice rather than passively accepting a tacit renewal, one of the most common billing mistakes.

At Unisave, we analyse your current contracts, compare available offers, and help you choose the formula best suited to your situation.
