Energy Saving Certificate

What is a CAE?

An Energy Saving Certificate (CAE) is an electronic document that guarantees that, after carrying out an energy efficiency action, a new final energy saving equivalent to 1 kWh has been achieved.

This instrument allows the monetisation of energy savings, recovering part of the cost of energy efficiency investments (change of lighting, improvement of thermal insulation, renovation of industrial or domestic equipment, etc.), as the end-user will be entitled to compensation if he/she sells the savings obtained for their subsequent certification through the CAE System.

Measures that have been implemented on or after 26 January 2023 (inclusive) and that comply with the requirements of the Energy Efficiency Directive and other regulations will be eligible to generate CAEs.

These actions may be standardised (those easily replicable and included in the Catalogue) or singular (those more complex or particular, not included in the Catalogue).

Eiffage Energía Sistemas is accredited as a delegated entity within the CAE system, enabling it, together with the liable taxpayers, to buy and sell energy saving certificates.

CAEs are regulated by RD 36/23, as well as by orders TED 815/23 and TED 845/23.

These are electronic documents that are generated from the annual savings (kWh/year) of energy efficiency measures (MAES) implemented by end consumers.

Standard (OM TED/845/2023) and singular performances can be certified.

Monetisation of savings

Eiffage Energía Sistemas has a specific area to provide specialised energy services.

We are pioneers in the provision of consultancy services in the field of AEC.

Energy Saving Certificates (CAE) must be validated by an ENAC accredited Conformity Assessment Body (CAB) and serve to formalise the amount of energy saved for a given investment. These savings can be sold.

Eiffage Energía Sistemas, as the delegated entity for the CAE system, offers support throughout the savings calculation and certification process, as well as in the sale and purchase process.

Comprehensive energy services

The knowledge of the installations accumulated in more than 400 maintenance contracts guarantees the quality of the energy services provided.

Eiffage Energía Sistemas does not only provide consultancy services in the field of CAEs. We can also offer services within a comprehensive programme aimed at reducing operational costs, including:
