At ACERTA, we verify the energy efficiency measures that enable companies to generate Energy Savings Certificates (CAE), providing technical rigor, independence, and ENAC-accredited certification to help companies achieve greater profitability when enrolling in the CAE system.
The Energy Saving Certificates (EAC) system allows for the recognition and appreciation of savings obtained after carrying out energy efficiency measures in facilities, processes or buildings.
In order for these savings to become valid certificates within the official system, it is necessary to technically verify the action taken and the calculation of the energy savings obtained.
At ACERTA, we conduct independent verification of standardized energy efficiency measures so that companies can obtain Energy Saving Certificates (CAE) in accordance with the system’s requirements, ensuring technical rigor, traceability, and security throughout the process.
Important note: This service is exclusively for companies, consultancies, and agents of the CAE system. We do not process requests from individuals.
Energy Saving Certificates (EACs) are electronic documents that officially certify the final energy saved after carrying out an energy efficiency action.
Each CAE is equivalent to 1 kWh saved and can be sold, transferred or used so that companies that are required to do so can comply with the obligations of the National System of Energy Efficiency Obligations (SNOEE).
The Energy Savings Account (CAE) system , promoted by the Ministry for Ecological Transition and the Demographic Challenge (MITECO) , allows for the recognition, monetization, and valuation of energy savings achieved by any individual or legal entity, including companies, public administrations, and public or private organizations. Furthermore, it contributes to Spain's compliance with the targets 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 it.
If your organization has developed an energy efficiency action, at ACERTA we can verify it and obtain your CAE with all the guarantees .
The Energy Savings Certificate System creates a market in which:
In order 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 measure, the issuance of the CAE (Certificate of Economic Activity) is requested through the system's electronic platform. Subsequently, the regional manager reviews the file and, once issued, the National Coordinator registers the certificates so that they can be bought, sold, or liquidated.

Organizations participating in the CAE system can gain significant advantages:
Energy efficiency incentives (EAIs) encourage investment in energy efficiency and promote a more sustainable, competitive economy aligned with European decarbonization goals.
At ACERTA, an entity accredited by ENAC for the verification of standardized measures, we provide technical rigor, independence and traceability throughout the process so that companies can obtain their Energy Saving Certificates.
We verified that the measures implemented meet the system requirements and that the calculated savings are correct and consistent with the actions taken.
