Energy Excise Duties: What Changes in 2026
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).
Impacts and Adaptations for Businesses
Companies must prepare for the increased costs associated with gas and electricity consumption from 2026 [11, 22]. It is essential to verify eligibility for exemptions and reduced rates, providing the required certifications. Unisave can assist you in this process.
Although the increased taxation on electricity finances renewable energies [19, 22], it requires an adaptation of companies' energy strategies. The third Multiannual Energy Program (PPE3), which will come into effect on February 1, 2026, sets ambitious targets for decarbonizing electricity and reducing the consumption of fossil fuels.
To optimize their costs, companies must carefully monitor developments in the energy market and the CRE's recommendations [6, 7, 8]. The increased volatility of electricity prices, with an average daily spread of €90/MWh in 2025, underscores the importance of proactive energy management.
