Tertiary Decree: Objectives and Monitoring in 2026

The Tertiary Decree, in effect since October 2019, plays a crucial role in the energy transition of companies. It mandates a significant reduction in energy consumption for tertiary buildings exceeding 1,000 m². The year 2026 marks an important milestone in monitoring these objectives.

Obligation to Reduce Energy Consumption

The companies concerned must reduce their energy consumption by 40% by 2030, compared to a reference year (after 2010). This ambitious framework encourages the adoption of energy efficiency measures and investment in cleaner technologies.

Monitoring via the OPERAT Platform of ADEME

Energy consumption is monitored via the OPERAT platform of ADEME (French Agency for Ecological Transition). Companies declare their annual consumption, allowing progress to be measured and areas for improvement to be identified.

Key point: The Tertiary Decree aims to transform the tertiary real estate sector into a major lever for the energy transition. Good data management on OPERAT is essential.

Reduction Targets of -40% by 2030

The 40% reduction target by 2030 is an intermediate step towards carbon neutrality. More ambitious targets are set for the following decades. Failure to meet these targets may result in penalties.

Energy Renovation: What Changes in 2026

The year 2026 brings significant changes in energy renovation for companies. These changes directly impact their obligations and opportunities.

New Regulatory Obligations

On January 1, 2026 (postponed to March 1, 2026), new regulatory obligations come into effect. They concern temperature regulation and insulation of heating and cooling networks. These measures aim to optimize the energy efficiency of buildings and reduce heat loss.

Postponement of the BACS Decree Obligations

Initially planned for 2025, the obligations of the BACS (Building Automation & Control Systems) Decree are postponed to January 1, 2030. This decree mandates the installation of automation and control systems for tertiary buildings. These systems allow precise monitoring and optimized management of energy consumption.

Increased Financial Aid via EECs

Financial aid via Energy Savings Certificates (EECs) is increased. EECs represent an important source of funding for energy renovation work. This allows companies to reduce their costs and improve their energy performance.

PPE3: France's Energy Strategy 2026-2035

The Multiannual Energy Program (PPE3) defines the priorities and objectives of French energy policy for the period 2026-2035. It guides investments and actions of sector stakeholders.

Decarbonized Electricity Production Targets

The PPE3 aims to produce between 650 and 693 TWh of decarbonized electricity by 2035. This ambitious objective relies on the development of renewable energies and the maintenance of a high-performance nuclear fleet.

Reduction of Fossil Fuel Consumption

Another key objective of the PPE3 is to reduce fossil fuel consumption to 330 TWh in 2035, compared to 900 TWh in 2023. This reduction involves improving energy efficiency, decarbonizing uses, and developing alternative energies.

Development of Renewable Energies

The PPE3 gives a central place to renewable energies, with ambitious targets for wind and photovoltaic power. France aims for 33% RES in final energy consumption by 2030 and aligns with the EU's RED III target (42.5%). These massive investments in RES create new opportunities for companies.

Opportunities in the Energy Market in 2026

The energy market in 2026 offers many opportunities for companies. It is important to anticipate developments and adapt your strategy.

Analysis of Energy Contracts

An in-depth analysis of energy contracts is essential to optimize costs and secure supply. It is important to understand the clauses, tariffs, and price revision conditions. At Unisave, we find that many companies are not aware of the ins and outs of their contracts.

Monitoring Prices on European Markets

Monitoring prices on European markets (EPEX SPOT, PEG Gas) allows you to anticipate fluctuations and make informed decisions about energy purchasing. Constant monitoring is necessary to seize opportunities and minimize risks.

Development of Renewable Energies and Storage Technologies

The development of renewable energies and storage technologies offers new perspectives for companies. Investing in self-consumption or storage solutions reduces dependence on fossil fuels and controls costs.

Energy Bills: Impacts and Anticipation 2026

The year 2026 will be marked by significant changes that will impact companies' energy bills. Proactive anticipation is therefore essential.

End of the Arenh Scheme and Impact on Electricity Prices

The end of the Arenh scheme (Regulated Access to Incumbent Nuclear Electricity) will have a significant impact on electricity prices. Companies must anticipate a potential increase in tariffs and explore alternatives to control their costs. See our article on understanding your electricity bill.

Strengthening of EECs and Influence on Gas Prices

The strengthening of EECs will also influence gas prices. Companies must take these developments into account in their budget and seek solutions to optimize their consumption.

Warning: The end of ARENH and the strengthening of EECs could lead to higher energy bills. Proactive management is crucial.

Cost Anticipation and Consumption Optimization

Accurate cost anticipation and consumption optimization are essential to controlling energy bills in 2026. This involves implementing rigorous monitoring, identifying energy saving opportunities, and investing in more efficient technologies. Do not hesitate to contact Unisave for an energy audit of your facilities and an analysis of your contracts.
