The Internet user intending to insert links from his/her own web pages to the Website must comply with the conditions listed below, without their ignorance preventing the resulting legal responsibilities:

  • The user is in no way allowed to reproduce the Website's pages (inline links, copy of the text, graphics, etc.);

  • It is prohibited, in accordance with the legislation applicable and in force at any given time, to establish frames of any kind involving the Website or enabling the visualization of the Content through Internet addresses other than the Website's and, in any event, when seen in conjunction with content unrelated to the Website, in a way that: (I) causes, or may cause, error, confusion or deception for the users regarding the true source of the service or Content; (II) assumes an act of comparison or unfair imitation; (III) serves to take advantage of the brand's reputation and REN's reputation; or (IV) is otherwise prohibited by the applicable law.

The page linking to the Website will not provide any false, inaccurate or incorrect information about REN or its workers, or about the quality of the services it provides.

In no case will there be mentioned on the page linking to REN that the latter gave its consent to the insertion of the link or that it, in any way, sponsors, collaborates, verifies or supervises the sender's services.

It is prohibited to use any brand name, in graphical or mixed form, or any other logo of REN on the sender's page, except in cases allowed by law or expressly authorized by REN and, in these cases, when a direct link to the Website is allowed, in accordance with the provisions of this clause.

The page establishing the link shall faithfully comply with the law and cannot, under any circumstances, display or link to its own content, or third-party content, that: (I) is unlawful, harmful or contrary to morals and good customs (pornographic, violent, racist, etc.); (II) induces or may induce in the User the false idea that REN endorses, supports, or, in any way, approves the ideas, statements or expressions, licit or illicit, of the sender; (III) is inappropriate or unsuitable to REN's operation, taking into account the location, content and topic of the sender's web page.




The content of this page is general in character and does not constitute, in any way, the provision of a service and, as such, the aforementioned information is insufficient for the User's decision-making.

REN is not responsible for the decisions made based on the information provided in the Website, nor for any damages or losses caused to the User or to third parties due to actions based solely on the information obtained in the Website.

The information provided by REN on this website is made available aggregated, meaning that it cannot be used to assess specific phenomena or constraints of the operation whose specific characterization, due to the detail, volume and nature, is provided by REN to the responsible supervisory entities, namely in the context of technical characterization of specific occurrences. Therefore, the detailed operational values presented in published reports, namely by ENTSO-E, may not be coincident.


Access to the Website does not imply an obligation by REN to control the absence of viruses, worms or any other harmful computer element. It is up to the User, in any case, to have appropriate tools for the detection and disinfection of harmful computer programmes.

REN is not responsible for damages in the computer equipment of the Users or third parties during the provision of the Website's service.


Access to the Website requires services and supplies from third parties, including transmission via telecommunications networks whose reliability, quality, continuity and operation are not under REN's purview.

REN is not responsible for damages or losses of any kind incurred by the User and motivated by faults or disconnections in telecommunications networks causing the suspension, cancellation or interruption of the Website's service, during the provision of its service or before it.


The access service to the Website includes technical linking devices, directories and also search tools enabling the User to access other pages and Internet websites (hereinafter ‘Linked Sites'). In these cases, REN acts as supplier of intermediation services and will only be responsible for the content and services supplied by the Linked Sites insofar as it has actual knowledge of the unlawfulness and has not disabled the link with the due diligence. If the User considers that there is a Linked Site with illicit or inappropriate content, he/she may report it to REN, in accordance with the procedure and effects set out in clause 6, without this communication, in any way, implying the obligation to remove the corresponding link.

Under no circumstances shall the existence of Linked Sites presuppose the existence of agreements with those responsible for them or with their holders, or the recommendation, promotion or identification of REN with the statements, content or services provided.

REN has no knowledge of the content and services in the Linked Sites, and therefore does not acknowledge liability for the losses caused by the unlawfulness, quality, outdatedness, unavailability, error or uselessness of the contents and/or services of the Linked Sites, nor for any other damage that is not directly attributable to REN.



REN processes your personal data in compliance with the provisions of the General Data Protection Regulation (EU) 2016/679, of 27 April ("GDPR") and Law no. 58/2019, of 8 August. REN respects the privacy of its Internet page users.
This section describes what we use your data for, how we process it, how we share it, how long we store it for, and the ways of contacting us to exercise your rights.
REN is the controller of your personal data, as per the GDPR definition.
REN appointed a Data Protection Officer, who can be contacted at the following e-mail address:


Personal data are collected by REN for certain, specific and legitimate purposes, respecting the principles of fairness, transparency, minimisation, integrity and confidentiality.
Your personal data are used by REN to comply with legal requirements and contractual commitments, to manage your activity and to provide services. Your data are not used for any purposes other than the purposes for which they were collected, which shall always be communicated to you.
For detailed information about the processing click here.
The personal data and any other information you supply to us by filling in an electronic form available on the Website (‘Data') shall be processed by REN for the purpose of managing the service requested. Filling in the forms is voluntary, and only the personal data needed to respond to your request shall be collected. Hence, only questions marked with an asterisk (*) are essential to fill in, given that without these data we cannot comply with, or perfectly comply with, the identified purposes.
When you grant consent, your personal data can be processed by REN to send you information of interest to you, through the delivery of newsletters. These personal data shall be stored for the respective processing period, and while you do not object to such processing.


Only personal data strictly necessary for the REN's activity shall be processed. The data may include your identification data (e.g. citizen card number), contact data (e.g. telephone number or address), tax data (e.g. NIF - tax number) and bank data (e.g. IBAN).


Your personal data are stored only for the period of time strictly necessary to allow (i) compliance with legal and regulatory requirements, (ii) compliance with a contract established with the data subject, (iii) management of the organisation's activity, and (iv) delivery of information and/or products requested by the data subjects.
When this period of time has elapsed, the personal data are erased by REN.


To satisfy your request, REN may have to communicate your personal data to the other companies that belong to the REN Group. The companies of the REN Group are listed and may be consulted at any time on the website:
Within the scope of its activity, REN may hire third parties to provide services. Sometimes the provision of these services requires these third parties to have access to personal data. Therefore, the personal data may be sent to these third parties in accordance with the purposes for which they were collected.
The entities that data may be sent to include service providers hired by REN, national authorities (e.g. CNPD [the Portuguese Data Protection Authority], Municipal Councils, Tax Authority), regulatory entities of the sector (e.g. ERSE [Energy Services Regulatory Authority], DGEG [Directorate General for Energy and Geology]) or banks.
REN does not sell the personal data it processes to third parties.


REN makes every effort to guarantee the maximum-security levels possible, suited to the nature of the data being processed. Hence, REN undertakes to implement suitable technical and organisational measures needed to protect the personal data it processes from accidental or illegal destruction, loss, alteration, dissemination or non-authorised access and use.
When data is transmitted to third parties, REN shall take suitable measures to make sure the entities that have access to the data are reputable and adopt the technical and organisational measures needed to protect the personal data and guarantee their confidentiality, integrity and availability. These measures shall be duly consecrated and safeguarded in a contract signed between REN and the third party.
When a service provider (processor) is hired by REN to process the subjects' personal data on its behalf, REN shall remain accountable for the personal data it supplies to the service provider.
In spite of the previous, the technical security in a medium such as the Internet is not impregnable, and malicious actions by third parties may take place, even if REN makes use of all available means to avoid them.

In the cases provided for in the General Data Protection Regulation, data subjects may also request erasure or object to the processing of their data, withdraw their consent to process them, request the portability of the data and not be subject to automated decisions about their personal data, by making a written request to the same addresses.
Users are also entitled to lodge a complaint to the Portuguese Data Protection Authority (CNPD).
