At ACERTA, we verify the energy efficiency measures that enable companies to generate Energy Savings Certificates (CAE), providing technical rigor, independence, and accredited verification to help them achieve greater profitability when enrolling in the CAE system.
The Energy Savings Certificate (CAE) systemrecognizes and quantifies the savings achieved through energy efficiency measures implemented in facilities, processes, or buildings.
In order for those energy savings to be converted into Energy Saving Certificates,it is necessary to conduct a technical verification of the work performed and to calculate the energy savings achieved.
At ACERTA, we conduct independent verification of CAEs associated with standardizedenergy efficiency measuresso that companies can submit them to regional authorities for recognition of the resulting energy savings.
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 implemented an energy efficiency measure, ACERTA can verify it with full assurance.
The Energy Savings Certificate System creates a market in which:
To obtain the CAE, they must be verified by an accredited entity, 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 accredited body for verifying the annual energy savings declared under the Energy Savings Certificate System for standardized measures, we ensure technical rigor, independence, and traceability throughout the entire process so that companies can obtain their Energy Savings Certificates.
We verified that the measures implemented meet the system requirements and that the calculated savings are correct and consistent with the actions taken.
Our work includes:
At ACERTA, we guarantee companiestechnical rigor and regulatory compliance so that their energy savings can be converted into valid CAEs within the official system.
Our mission is to build trust through accredited verification.
Within the framework of the CAE System, this means providing companies with a reliable, traceable verification process that complies with regulatory requirements, ensuring that the reported energy savings are real, measurable, and valid.
If you are a business and have implemented any energy efficiency measures, contact our technical team to obtain your CAEs accurately, quickly, and with full assurance.
It is an official certificate that verifies the final energy saved after an energy efficiency action verified by an accredited entity.
They allow you to monetize savings, meet energy efficiency obligations, or transfer them within the CAE system.
