Natural or legal person of a public or private nature that carries out the investment of the energy efficiency performance with the purpose of obtaining final energy savings, for itself or for a third party. It can also be the one to whom the savings generated by such action have been assigned.

As an example, a municipality decides to carry out a certain action and as a consequence of this decision signs an energy performance contract with a company. In this case, the original owner of the savings will be the municipality, not the company.

In the event that the municipality has signed an assignment agreement with the company, the company would be the owner of the savings.

Legal entity of a public or private nature that can assume, totally or partially, the delegation of obtaining new annual energy savings from one or more obligated parties.

Entity accredited by the National Accreditation Entity (ENAC) in charge of verifying the energy savings obtained by the implementation of one or more energy efficiency actions.

It may be freely chosen by the obligor or the delegated party from among those that provide this service.

Gas and electricity trading companies, wholesale petroleum product operators and wholesale liquefied petroleum gas operators.

They have an obligation to save energy after 2 years of operation and must compensate emissions through an annual contribution to the SNOEE through a contribution to the FNEE and a part can be compensated through the CAE.

The European Regulation and its Spanish transposition obliges Obligated Parties (SO) to to commit to saving energy from their annual sales. This obligation has resulted in a financial contribution by these SOs to the National Energy Efficiency Fund (FNEE).

This FNEE is used by the State as a mechanism to channel financial resources towards initiatives that help optimize energy use, in order to improve environmental sustainability and strengthen the country’s energy security.

A Certificate of Energy Saving (CAE) is a document that guarantees that, after carrying out an energy efficiency action, a new final energy saving equivalent to 1 kWh has been achieved. Thus, if an action is undertaken that implies a new annual saving of 1000 kWh (equivalent to 1 MWh), 1000 CAE can be obtained.

This instrument makes it possible to monetize energy savings, recovering part of the cost of investments in energy efficiency (change of lighting, improvement of thermal insulation, renovation of industrial or domestic equipment, etc.), since the end user will be able to receive a consideration if he sells the savings obtained for subsequent certification through the CAE System.

Annually, a final energy savings obligation is imposed on obligated entities (SO). The presentation of CAE is an alternative and voluntary instrument to the economic contribution to the National Energy Efficiency Fund for the compliance of such obligation.

To obtain CAE, companies or entities must implement energy efficiency measures in their facilities or processes.

Theoretically, it applies to any action that results in energy savings. These measures can range from installing more efficient equipment to optimizing industrial processes to reduce energy consumption.

In practice, there will be two types of actions:

• Standardized: They are included in a catalog, have characteristics and technical particularities and are justifiable through cards already predefined by the BOE.
• Singular: They are out of the catalog. Requires specific intervention by an official savings verifier to apply for CAE.

Photovoltaic is not included, as it does not involve final energy savings (solar thermal, however, can generate CAE as long as it is not a mandatory action).

Once the measures have been implemented, the energy savings obtained are calculated and the corresponding certificates are issued.

A CAE has a single value of 1kWh of final energy consumption savings.

1 CAE = 1KWh of final energy savings.

1000 CAE = 1Mwh of final energy savings.

As for the monetary value, the National Coordinator of the PPA System will provide, from the electronic platform, the average price of the sale of PPAs.

Within the CAE System, both in standardized actions and in singular actions, only the final energy savings achieved in one year will be taken into account, not the accumulated savings throughout the useful life of the action.

Obligated parties are assigned a nationwide annual energy savings quota, known as savings obligations. This savings obligation is expressed in GWh/year or its equivalent in kWh/year.

A CAE may be registered up to three years after the performance that generated the certified energy savings has been carried out, provided that the execution of the performance has started since the date of entry into force of the Royal Decree (January 26, 2023) and before January 1, 2031.

The CAE will be valid for three (3) years from the date on which the performance of the action generating the energy savings was completed (when the savings begin to be generated), or until December 31, 2030 (inclusive), whichever is earlier.

Once a CAE reaches its expiration date it will lose its validity.

Holder of the CAE: It can only be an obligated subject (SO) or a delegated subject (SD) in favor of whom a CAE has been issued or who has acquired it through a legal purchase and sale business.

In this case, you will be considered an Energy Saving Owner, in accordance with the provisions of Article 12.1 of Royal Decree 36/2023, of January 24, which establishes a system of Energy Saving Certificates.

Such energy savings may be transferred to a third party by signing a private agreement or directly to an SO or SD by signing a CAE Agreement (Royal Decree 36/2023, January 24, Article 12.1; Order TED/815/2023, July 18, Article 11).

The CAE agreement is an agreement signed between the obligated entity or the delegated entity and the owner of the energy savings, whereby the latter assigns such savings to the obligated entity or the delegated entity in exchange for a consideration.

The delegation contract is a private law agreement signed between an obligated subject and a delegated subject whereby the latter (SD) undertakes to obtain and settle on behalf of the former (SO) a number of CAE equivalent to a given amount of final energy savings.

It is recalled that in no case the delegated subject assumes the annual obligation, in whole or in part, of the obligated subject or the condition of obligated subject, maintaining in any case the referred obligation in the obligated subject.

The body or entity responsible for energy efficiency in the autonomous community where the energy saving action has been carried out (autonomous community manager).

For this purpose, the obligor or the delegated subject must submit a request to the regional manager for the issuance of the CAE, together with a file that includes the favorable opinion and the verifier’s report (Royal Decree 36/2023, January 24, Article 13).

The National Coordinator of the CAE System is the administrative body in charge of ensuring the correct operation of the CAE System. The national coordination of the PPA System will correspond to the General Directorate of Energy Policy and Mines of the Ministry for Ecological Transition and Demographic Challenge (Royal Decree 36/2023, January 24, Article 16).

The minimum file size to make a request for the issuance of CAE is 30 MWh, which can be covered by the sum of the savings of the different actions (standardized and/or singular) included in the request (Order TED/815/2023, of July 18, Article 14.6).

Only those who have the consideration of obligated parties (SO) of the National System of Energy Efficiency Obligations (SNOEE) with an energy saving obligation equal to or greater than 50 MWh or who have been accredited as delegated parties (SD) can request the issuance of CAE (Order TED/815/2023, of July 18, Article 14.1).
