Energy Saving Certificate (CAE) for Companies

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.

What is an Energy Saving Certificate (ESC)?

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.

How the CAE System Works

The Energy Savings Certificate System creates a market in which:

  • Obligated entities (companies with an annual energy saving obligation) can acquire CAE or generate their own.
  • Delegated entities may obtain savings on behalf of obligated entities, upon prior accreditation.
  • Companies and entities that carry out energy efficiency actions can monetize their savings through their sale.

To obtain the CAE, they must be verified by an accredited entity, such as ACERTA.

CAEs are generated from:

  • Standardized procedures (included in an official catalog).
  • Unique performances (more complex and not included in the catalog).

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.

Benefits of CAE for companies

Organizations participating in the CAE system can gain significant advantages:

Monetize energy savings by selling or transferring them to obligated entities.

Strengthen ESG positioning and commitment to sustainability.

Increase the real energy efficiency of your facilities and processes

Access green incentives and financing linked to energy savings

Improve competitiveness by reducing operating costs

Energy efficiency incentives (EAIs) encourage investment in energy efficiency and promote a more sustainable, competitive economy aligned with European decarbonization goals.
