Key data
| Regulation | Resolution of July 30, 2026, from the General Directorate of Energy Planning and Coordination |
|---|---|
| Publication | August 4, 2026 |
| Entry into force | August 5, 2026 |
| Modified sheets | TRA020, TRA040, TRA050 (split into TRA050P and TRA050E) |
| Modified regulation | Order TED/845/2023, of July 18 — Catalog of standardized energy efficiency measures |
| Transitional period | 4 months for actions already initiated under previous sheets |
| Affected parties | Transport companies, collaborative mobility platforms, individuals and companies with electric fleet renewal |
| Category | Energy / Energy Savings Certificates (CAE) |
| Year | 2026 |
Transport companies, carpooling platforms and any entity requesting Energy Savings Certificates (CAE) for electric fleet renewal must review their open files. The Resolution of July 30, 2026 partially updates Annex I of Order TED/845/2023 and modifies three key sheets in the CAE catalog in the transport sector, effective the day after its publication.
The change is not cosmetic: it affects measurement periods, identity verification requirements, route traceability and the way savings are calculated for electric vehicles depending on the type of applicant.
What does this regulation establish?
The resolution updates three sheets in the CAE catalog in the transport sector. Below is the detail of each change:
| Sheet | Name | Main change |
|---|---|---|
| TRA020 | Efficient driving assistance systems | Expansion of the scope of assistance systems and extension of the measurement period to 90 days |
| TRA040 | Collaborative mobility (carpooling) | Moves from urban mobility to include routine routes in rural areas; new identity verification and traceability requirements |
| TRA050P | Electric fleet renewal — Individuals (new) | Specific sheet for individuals with vehicle age factor in the savings calculation |
| TRA050E | Electric fleet renewal — Companies (new) | Specific sheet for companies with breakdown of heavy vehicles in the savings calculation |
The previous TRA050 sheet is replaced by the two new sheets (TRA050P and TRA050E). Actions already initiated under the original TRA050 sheet can be completed during the four-month transitional period from entry into force.
Economic and operational impact
CAEs are instruments that allow companies and individuals to certify energy savings and obtain economic value from them. Any change in the sheets directly affects the amount of certificates that can be obtained and the requirements to accredit them.
- TRA020 (efficient driving): The new 90-day measurement period can increase the base for calculating creditable savings, but also requires keeping monitoring systems active for longer. Companies with fleets already using these systems should review whether their telemetry contracts cover that horizon.
- TRA040 (carpooling): The extension to rural areas opens the door to new actions outside urban environments, but the new identity verification and traceability requirements imply greater documentary burden for platforms. Without that documentation, the CAEs will not be valid.
- TRA050P and TRA050E (electric vehicles): The split into two sheets differentiates the tax treatment and calculation between individuals and companies. Companies with heavy vehicles in their fleet can obtain a more precise and potentially more favorable savings calculation thanks to the specific breakdown.
Who does it affect?
- Freight and passenger transport companies requesting CAE for efficient driving systems (TRA020)
- Collaborative mobility platforms (carpooling) operating in urban or rural environments (TRA040)
- Individuals replacing their vehicle with an electric one and wanting to certify the savings (TRA050P)
- Companies with fleets including electric vehicles, especially with heavy vehicles (TRA050E)
- CAE project managers and energy advisors processing files in the transport sector
- Any entity with actions in progress under the previous TRA020, TRA040 or TRA050 sheets before the resolution
Practical example
A logistics distribution company has an open CAE file under the TRA050 sheet (electric fleet renewal) initiated in July 2026. With entry into force on August 5, 2026, that sheet no longer exists as such: it has been replaced by TRA050P and TRA050E.
Thanks to the four-month transitional period, the company can complete and submit its file under the original TRA050 sheet until approximately December 5, 2026. From that date, it must mandatorily use the TRA050E sheet, which requires breaking down heavy vehicles in the fleet for the savings calculation.
If the company has both passenger cars and trucks in its electric fleet, the new TRA050E breakdown can be more favorable, since heavy vehicles have a higher base consumption and therefore potentially higher creditable savings.
What should companies do now?
- Identify if you have open CAE files in transport: Review whether you have actions in progress under the TRA020, TRA040 or TRA050 sheets. If so, you have a maximum of four months from August 5, 2026 to complete them under the previous sheets.
- Decide whether it is convenient to migrate to the new sheets before the deadline: In some cases, especially with heavy vehicle fleets, the new TRA050E sheets can be more favorable. Analyze with your CAE manager whether it is worth changing now.
- Update traceability systems for TRA040: If you operate a carpooling platform, review your identity verification processes and route registration. Without that documentation, CAEs will not be recognized under the new sheet.
- Verify the coverage of monitoring systems for TRA020: The new 90-day measurement period may require adjustments to telemetry contracts or efficient driving assistance systems installed.
- Inform your energy advisor or CAE project manager: Make sure that whoever processes your files knows about the changes and applies the correct sheets according to the type of action and applicant.
Frequently asked questions
How much time do I have to adapt my open CAE files under the previous sheets?
You have a four-month transitional period from entry into force (August 5, 2026), that is, until approximately December 5, 2026. After that deadline, only the new TRA020, TRA040, TRA050P and TRA050E sheets will be valid.
What is the difference between TRA050P and TRA050E?
The TRA050P sheet is designed for individuals replacing their vehicle with an electric one and incorporates a vehicle age factor in the savings calculation. The TRA050E sheet is for companies and includes a specific breakdown of heavy vehicles, which can result in a more precise and potentially more favorable savings calculation for mixed fleets.
What new requirements does the TRA040 sheet demand for carpooling?
The new TRA040 requires user identity verification and route traceability. Additionally, it expands the scope of application: it is no longer limited to urban mobility, but also includes routine routes in rural areas. Without that documentation, CAEs requested under this sheet will not be valid.
What changes in the TRA020 efficient driving sheet?
The TRA020 sheet expands the scope of efficient driving assistance systems and extends the measurement period to 90 days (compared to the previous period). This can increase the base for calculating creditable savings, but requires keeping monitoring systems active for that entire period.
What regulation does this resolution modify?
It partially modifies the Annex I of Order TED/845/2023, of July 18, which approves the catalog of standardized energy efficiency measures. Only the sheets in the transport sector (TRA020, TRA040 and TRA050) are updated; the rest of the catalog remains unchanged.
