If you have CAE files open or in preparation for vehicle replacement, this correction affects you today. The Resolution of 16 September 2026 from the General Directorate of Energy Planning and Coordination rectifies five material errors detected in the update of the standardized energy efficiency measures catalog published on 30 July 2026. The errors affect legal references, vehicle consumption data and the identification of documents in leasing operations.
What does this regulation establish?
This resolution corrects errors in the update of Annex I of Order TED/845/2023, which regulates the catalog of standardized energy efficiency measures for obtaining Energy Savings Certificates (CAE). The five rectified errors are concentrated in three sheets in the transport sector:
| Sheet | Name | Error corrected |
|---|---|---|
| TRA040 | Collaborative mobility | Incorrect legal references |
| TRA050.P | Vehicle replacement by natural person | M2 diesel vehicle consumption data omitted (15.5 L/100km); errors in circulation permit identification |
| TRA050.E | Vehicle replacement by entities | Confusion between new and old vehicle in leasing operations |
The detail of each correction is as follows:
- TRA040 (collaborative mobility): Legal references that appeared incorrect in the 30 July 2026 version are corrected.
- TRA050.P (natural person): The consumption data for M2 diesel vehicles is incorporated, which had been omitted: 15.5 L/100km. Additionally, errors in the identification of the circulation permit required as supporting documentation are corrected.
- TRA050.E (entities): The confusion between new vehicle and old vehicle in the context of leasing operations is corrected, which directly affects the calculation of accreditable energy savings.
Economic and operational impact
CAEs are instruments that allow companies and individuals to accredit energy savings and obtain economic compensation for them. An error in supporting documentation or in the reference consumption data can result in invalidation of the file or reduction of accreditable savings, with the consequent impact on the certificate value.
The specific operational effects are:
- Supporting documentation: Files using sheets TRA050.P or TRA050.E must verify that the referenced circulation permit corresponds to the correct vehicle (new or old as applicable), especially in leasing operations.
- Energy savings calculation: The 15.5 L/100km figure for M2 diesel vehicles is now the official reference value in TRA050.P. Files processed with the erroneous version of 30 July 2026 may have used incorrect or missing data.
- Legal references in TRA040: Any collaborative mobility file citing the reference regulations must be updated with the corrected references.
Who does it affect?
- Companies with vehicle fleets that are processing or will process CAE for vehicle replacement (sheet TRA050.E).
- Individuals (natural persons) requesting CAE for renewal of their own vehicle (sheet TRA050.P), especially if the replaced vehicle is M2 diesel category.
- Public entities with fleet renewal programs linked to obtaining CAE.
- Energy managers and advisors preparing CAE files in the transport sector.
- Leasing or rental companies involved in vehicle replacement operations with associated CAE processing.
- Collaborative mobility project promoters using sheet TRA040.
Practical example
A passenger transport company processes a CAE for the replacement of several M2 diesel category buses using sheet TRA050.E. Some of the vehicles are acquired through leasing.
With the erroneous version of the catalog (30 July 2026), the file could have:
- Assigned the circulation permit of the new vehicle where the old vehicle's permit should have been (or vice versa), generating a documentary inconsistency.
- Calculated energy savings without the official consumption data of 15.5 L/100km for M2 diesel, as it was omitted from sheet TRA050.P.
- Confused the new vehicle with the old vehicle in the leasing operation, altering the consumption differential on which the CAE is calculated.
With the correction in force from 28 September 2026, the file must use the 15.5 L/100km figure, correctly identify each vehicle in the documentation and apply the updated legal references. If the file was already submitted with erroneous data, it is advisable to review whether it needs to be corrected before it is resolved.
What should companies do now?
- Review CAE files in progress using sheets TRA040, TRA050.P or TRA050.E: verify that documentation and calculations comply with the corrected version of the catalog, effective from 28 September 2026.
- Check the M2 diesel consumption data in all TRA050.P files that include vehicles in this category: the official value is 15.5 L/100km. If another value was used or the field was empty, correct the file.
- Verify the identification of the circulation permit in TRA050.P sheets: ensure that the referenced document corresponds to the correct vehicle as required.
- Review leasing operations in TRA050.E: confirm that the distinction between new vehicle and old vehicle is correct throughout the file documentation.
- Update legal references in TRA040: if references from the 30 July 2026 version have been cited, replace them with the corrected ones.
- Inform energy managers and advisors working on these files to apply the corrected version of the catalog from today.
Frequently asked questions
Which CAE sheets in the transport sector have been corrected?
Three sheets have been corrected: TRA040 (collaborative mobility), TRA050.P (vehicle replacement by natural person) and TRA050.E (vehicle replacement by entities). In total, five material errors detected in the catalog update published on 30 July 2026 are rectified.
What is the official consumption for M2 diesel vehicles for CAE calculation?
The corrected official data is 15.5 L/100km for M2 diesel category vehicles. This value had been omitted from sheet TRA050.P in the 30 July 2026 version and is incorporated with effect from 28 September 2026.
Do these corrections affect CAE files already submitted before 28 September 2026?
If a file was prepared and submitted using the erroneous version of the catalog (published on 30 July 2026), it may contain incorrect data or incorrectly identified documentation. It is recommended to review whether the file is pending resolution and, if so, consider voluntary correction to avoid problems in processing.
What error affects leasing operations in sheet TRA050.E?
The correction resolves a confusion between the new vehicle and the old vehicle in the context of leasing operations within sheet TRA050.E. This error could alter the consumption differential on which accreditable energy savings are calculated and, therefore, the value of the CAE obtained.
When is it mandatory to apply the corrected catalog?
The correction resolution entered into force on the same day of its publication in the BOE: 28 September 2026. All CAE files in the transport sector processed from that date must use the corrected version of sheets TRA040, TRA050.P and TRA050.E.
