Energy Saving Certificates - CAE

At ACERTA, we verify energy efficiency measures that enable the generation of Energy Saving Certificates (CAE), providing technical rigor, independence, and ENAC-accredited certification to achieve greater profitability when registering with the CAE system.

What is an Energy Saving Certificate (ESC)?

The Energy Savings Certificates (ESCs) are electronic documents that officially certify the final energy saved after carrying out an energy efficiency measure.                                           

Each CAE is equivalent to 1 kWh saved and can be sold, transferred, or used so that companies that are required to do so to comply with the obligations of the National Energy Efficiency Obligations System (SNOEE). 

The CAE system, promoted by the Ministry for Ecological Transition and Demographic Challenge MITECO, allows the savings obtained by any individual or legal entity such as companies, administrations, and public or private entities. In addition, it contributes to Spain's compliance with the objectives set by the European Union's Energy Efficiency Directive. 

Participation in this system makes it easier for organizations to promote sustainable measures, improve their efficiency, and obtain a direct economic return for doing so. 

If your organization has developed an energy efficiency plan, at ACERTA we can verify it and obtain your CAE with full guarantees. 

How the CAE System Works

The Energy Savings Certificate System creates a market in which:

To  be able to obtain the CAE, it is mandatory that they be verified by an entity accredited by ENAC, such as ACERTA.  

CAEs are generated from:

After verifying the measurement, the CAE is requested via the system's electronic platform. The regional manager then reviews the file and, once issued, the National Coordinator registers the certificates so that they can be bought, sold, or settled. 

Benefits of CAE for companies

Organizations participating in the CAE system can obtain significant advantages: 

CAEs encourage investment in energy efficiency and promote a more sustainable, competitive economy that is aligned with European decarbonization goals.
