Avoid mistakes when applying for MITECO CAEs. Optimize your energy savings, access grants, and improve your carbon footprint. Check out this practical guide!


Energy Savings Certificates (CAEs) are official documents that certify the energy savings achieved through efficiency measures. Issued by authorized entities under the supervision of MITECO, they allow companies and industries to record their savings, access MITECO grants, and monetize their efforts. Their dual purpose is to certify savings and serve as a strategic tool for corporate sustainability.


Correctly applying for the CAE energy savings certificate is essential to comply with regulations, improve your carbon footprint, and contribute to environmental quality. However, many applications are rejected due to avoidable errors that can be resolved with proper planning.


Common Mistakes When Applying for CAEs


Poorly Prepared Certificates

  • Use of estimated data without technical support

  • Failure to register the certificate in the system of the Community of Madrid or other autonomous regions

  • Lack of comparison between the pre- and post-measure states


Incomplete Documentation

  • Missing invoices, reports, or photographic evidence

  • Incorrect tax data, wrong dates, or invalid digital signatures

  • Omission of project tracking number and traceability


Ineligible Measures

  • Actions that do not comply with MITECO CAEs regulations or official CAEs datasheets

  • Lack of evidence of actual energy savings, preventing accurate CAEs calculation


Lack of Procedural Knowledge

  • Starting works without registering the prior energy certificate

  • Not consulting a delegated entity or accredited technician


These errors can prevent access to MITECO grants and subsidies, hinder regulatory compliance, and damage a company’s environmental reputation.


How to Avoid Mistakes When Applying for MITECO CAEs


Advance Planning


Ensure that the measures are listed in the MITECO CAEs datasheets and that energy savings can be justified with real data.


Rigorous Certification


Use official tools like C3X and register both the prior and post-certificates. The MITECO carbon footprint calculator can help estimate environmental impact.


Technical Guidance


A delegated entity familiar with MITECO CAEs regulations can guide the process, prevent errors, and facilitate carbon footprint registration.


Document Review


Make sure all documentation is signed, dated, and supported by technical and photographic evidence.


Continuous Updates


Platforms like Certicalia and Feníe Energía offer updated information on CAEs grants, procedures, and regulatory changes, including MITECO 2024 emission factors.


Benefits of a Properly Processed CAE


Correctly applying for the CAE energy savings certificate allows companies to:

  • Access MITECO grants and monetize energy savings

  • Meet CAEs system goals in the Community of Madrid and nationwide

  • Contribute to decarbonization and improved air quality

  • Strengthen market position as a climate-conscious company

  • Advance toward a green economy aligned with European targets


Moreover, proper CAE management enables companies to integrate energy efficiency into their corporate strategy, reinforcing MITECO environmental quality and assessment, and enhancing reputation among clients and investors.


Error-Free Energy Efficiency


Properly applying for MITECO CAEs not only ensures regulatory compliance, it unlocks economic, environmental, and reputational benefits. With solid planning, technical advice, and tools like the MITECO carbon footprint calculator, companies can turn energy savings into a strategic asset.
