Energy aid extension 2026: 20 cents/liter and gas price cap for transporters, SMEs and self-employed

Key data

Transporters, farmers, livestock breeders, fishermen and SMEs that depend on fuel or natural gas have certainty until December 31, 2026: aid does not disappear. The Royal Decree-Law 25/2026, published on September 30, extends the Comprehensive Response Plan to the Middle East Crisis in response to persistent energy market instability.

The Government's argument is clear: energy CPI in the transport sector has reached 9.5% year-on-year and the ECB forecasts that the inflationary peak in the eurozone will reach 3.6% in the fourth quarter of 2026. Withdrawing support now would worsen the impact on economic activity. Withdrawal will be gradual, conditional on market stabilization.

What does this regulation establish?

RDL 25/2026 extends until December 31, 2026 the set of measures from the Comprehensive Response Plan to the Middle East Crisis. The specific measures are as follows:

The regulation expressly activates the safeguard mechanisms provided for in RDL 18/2026, which are triggered when energy CPI in transport exceeds certain thresholds. The data that activates them in this case is the 9.5% year-on-year recorded in that sector.

The withdrawal of support will not be abrupt: the decree itself establishes that it will be gradual as markets stabilize, with special attention to the fourth quarter of 2026, when the ECB forecasts the inflationary peak of 3.6% in the eurozone.

Economic and operational impact

For companies with vehicle fleets or agricultural machinery, maintaining the 20 cents/liter discount on diesel is the measure with the greatest direct impact. A company consuming 10,000 liters of diesel per month saves €2,000 monthly compared to the price without tax discount.

In gasoline, the discount is reinforced in October compared to the 5 cents/liter in September. Although the decree does not specify the exact amount of the reinforcement, the effect is positive for fleets operating with gasoline vehicles.

In natural gas, the 45% cap on the Last Resort Tariff protects both households and SMEs supplied through this regulated tariff. Without this limit, wholesale market volatility could be fully passed on to the bill.

The risk for companies is the uncertainty post-December 2026: if markets do not stabilize, the Government must decide between a new extension or gradual withdrawal. Companies with high energy dependence should plan scenarios for 2027 without assuming that support will continue automatically.

Who does it affect?

• Professional transporters: maintain full direct aid and 20 ct/liter discount on diesel.
• Farmers and livestock breeders: direct aid without cuts until end of 2026.
• Fishermen: direct aid maintained in full.
• SMEs with fleets or machinery: benefited by the reduction in Hydrocarbon Tax on diesel and gasoline.
• Self-employed with professional vehicle: fuel discounts applicable at each refueling.
• Households and SMEs with natural gas TUR contract: protected by the 45% cap on regulated tariff.
• Companies with high energy exposure (logistics, industry, hospitality): lower pressure on operating costs during Q4 2026.

Practical example

A road transport company with 10 trucks consuming an average of 1,500 liters of diesel per truck per month has a total monthly consumption of 15,000 liters.

With the 20 cents/liter discount on Hydrocarbon Tax, the direct monthly savings is €3,000 (15,000 liters × €0.20). In the three remaining months of 2026 (October, November and December), accumulated savings amount to €9,000.

If this company also has facilities with a natural gas contract under the Last Resort Tariff, the 45% cap guarantees that its gas bill will not rise beyond that percentage, regardless of what happens in the wholesale market during Q4 2026, which is precisely the quarter when the ECB forecasts the inflationary peak of 3.6%.

What should companies do now?

1. Verify that discounts are applied correctly at each refueling: the 20 ct/liter discount on diesel and the reinforced discount on gasoline from October should be reflected in the pump price. If not, contact your fuel supplier.
2. Review your natural gas contract: if you have the Last Resort Tariff, check that your supplier does not apply increases exceeding 45%. If you have a free market contract, the cap does not apply directly to you, but you can negotiate with the regulatory context as an argument.
3. Confirm access to direct sectoral aid: transporters, farmers, livestock breeders and fishermen should verify with their sectoral association or manager that direct aid remains active and that application or renewal procedures are up to date.
4. Plan energy scenarios for 2027: measures expire on December 31, 2026. Prepare an energy cost budget for 2027 with and without aid, so you don't depend on an extension that is not yet guaranteed.
5. Monitor the fourth quarter: Q4 2026 is the critical period according to the ECB (inflationary peak of 3.6%). Any decision on gradual withdrawal will be announced in that quarter. Keep regulatory alert active.
