Data Protection


Thank you for visiting our website and your interest in our company and what we do. Protecting your personal data is important to us. The following text describes which personal data we collect, how we process it, and what rights you have in connection with your personal data. These provisions apply whenever you visit our website or use our services, including events, which refer or include a link to this data protection information. Any further information that may be provided to you regarding the processing of personal details will apply in addition to these provisions.

The party responsible for processing your data (the “data controller”) is:

TransnetBW GmbH
Pariser Platz
Osloer Strasse 15-17
70173 Stuttgart
Tel.: +49 711 21858-0

Our data protection officer can be reached at, and will be happy to assist with any questions you may have on data protection.

We collect and process your data only if we have obtained your permission to process it, or if processing is permitted by law. We guarantee that we use all incoming data only for its intended purpose.

Automatically saved data

When you visit our website, we save the following data that your browser transmits to us: your IP address or the IP address of your Internet Service Provider; the website that directed you to us; the type of browser you use; your operating system and platform; the pages that you called up at; and the dates and times you accessed them. We process this log data without reference to the identity of the user or other profiling, on the basis of Art. 6 para 1 (f) GDPR and only to the extent necessary, to enable us to perform statistical analyses for our business, for security and to optimise our online content. If an IP address is saved, it will be deleted or anonymised after no more than seven days. It is essential for this data to be collected and for the data to be stored in log files to enable the website to function. Users therefore have no right of objection in this regard.

If you make use of elements on our website that require registration or explicitly require your details to be entered, additional data will be saved. Personal details such as your name, address, telephone number and e-mail address are saved only when you provide them to us voluntarily, as part of the registration process, for example, or for a survey or competition, to execute a contract, or to order information material or display a newsletter, or if you otherwise actively make contact with us, e.g. via e-mail. In other words, it is entirely your decision whether you make any details available to us, and which details you choose to provide. You will find advice about this in the following text.

Use of Cookies

When you visit particular parts of its website, TransnetBW makes use of cookies to offer you more personalised services. Cookies are small text files that a web server can send to your computer to identify it. This is done on the legal basis of Art. 6 para 1 (f) GDPR for the purpose of managing the connection while you visit websites and to save your settings to make it easier for you to use our website. Some functions on our website will not work without the use of these cookies, and it would not otherwise be possible to offer them. They are not associated with your personal details. Our legitimate interest in processing cookies is derived from the above purposes. You can set your browser to notify you each time a cookie is saved, making their use transparent for you. You can adjust your browser settings to control how cookies are used, and to what extent, or you can turn them off completely. With the exception of cookies from Google Analytics, cookies are deleted at the end of each session (e.g. when you log out or close your browser). We also use cookies that enable us to analyse the user behaviour of visitors to our website by examining data such as search expressions that are entered, time spent on the individual pages of the website, and use of website functions. The legal basis for this data processing is Art. 6 para 1 (f) GDPR and s. 15 para 3 of Germany’s Telemedia Act (TMG). The use of cookies enables us to optimise our website and structure it more in accordance with user needs. These purposes also underlie our legitimate interest in the use of this data. The cookies are deleted at the end of a predetermined period. Cookies from Google Analytics are stored on our website for a maximum of two years.


If you are legally obliged to supply information to TransnetBW regarding the reallocation charge and you log in to the energy industry portal, we will process your data solely for the purposes of our commercial relationship. When you register on our online platform, you will be advised which information must be supplied. You decide whether to provide any further details in addition to these. Details regarding third parties may be provided only with their permission or when otherwise permitted by law.

User profiles are not public and cannot be viewed by other users. When you terminate your registration or delete your profile, you are responsible for saving your data; we are entitled to permanently delete all user data saved during the term of the agreement unless legal or contractual archiving obligations dictate otherwise.

TransnetBW will disclose your personal data only if and to the extent that this is legally required.

Making Contact

If you contact us using a form on, this will use 128-bit encryption as a matter of course. If you use your private e-mail account rather than the TransnetBW forms that are secured with 128-bit SSL encryption, please note that you must ensure your own security measures are in place to guarantee the security of your transmission.

We therefore recommend you use the encrypted TransnetBW forms. If the form is not encrypted, this will be the result of a technical problem, and we cannot assume liability for the security of your data transmission. The closed “lock” symbol in your browser window will show whether the form is encrypted. The legal basis for data processing is Art. 6 para 1 (a) GDPR. The data that you send us with your enquiry is saved for the purpose of processing your enquiry, and will be deleted once the result has been achieved.

Newsletter services

If you subscribe to a TransnetBW newsletter, we will regularly contact you with the latest information about our projects and services. To subscribe to the newsletter, you must provide us with a valid e-mail address and register to receive the newsletter. We will then check your e-mail address to determine whether you have access to the specified e-mail account (known as a “double opt-in process”). We will use your e-mail address only to send our newsletter, and will not disclose it to third parties. If you register for our newsletter, we will log your IP address and the date and time of registration for the record. The data collected when you order the newsletter will not be combined with other data collected via our website unless you give us your approval to do so. The legal basis for data processing is your voluntarily given approval to receive the newsletter, as per Art. 6 para 1 (a) GDPR. If you no longer want to receive the newsletter, you can withdraw your agreement with future effect at any time by clicking on the link provided.

The data that is collected in connection with the newsletter will be deleted no later than three years following the end of the year in which you register.

Recipients of your personal data

We treat your data as confidential. Within TransnetBW, only the departments and employees that need your data for the above purposes are given access to your data.

We disclose personal data to third parties only if this is necessary for the above purposes and is legally permitted, or if you have given your prior agreement. If service providers are brought in to assist with the performance of our obligations, e.g. specialists in analysis or the destruction of documents and data media, the performance of such contracts will be subject to the stringent conditions of Art. 28 GDPR.

Google analytics

This website uses Google Analytics, a web analysis service of Google Inc. (“Google”). Google Analytics uses “cookies”, which are text files that are stored on your computer and make it possible to analyse the use that you make of this website. The information that is generated by the cookie regarding your use of this website is generally transmitted to a Google server in the US and is saved there.

If IP anonymisation is activated on this website, however, Google will first abbreviate your IP address within the member countries of the European Union or the other signatory countries to the Agreement on the European Economic Area. Only in rare instances is the full IP address transferred to a Google server in the US and truncated there. IP anonymisation is active on this website. On our behalf, Google will use this information to evaluate your use of this website to draw up reports about website activity and to perform additional services for the website operator in connection with the use of the website and the Internet as a whole.

The IP address transmitted from your browser in connection with Google Analytics will not be linked with any other data held by Google. The legal basis for data processing is Art. 6 para 1 (f) GDPR and s. 15 para 3 TMG. Our legitimate interest is derived from the above purposes.

You can stop cookies from being saved by adjusting the settings on your browser software; however, we must warn you that this may restrict your ability to use all of the functions of this website to their full extent. You can also prevent the data generated by the cookie relating to your use of the website (including your IP address) from being collected and processed by Google by downloading and installing the browser plugin available from this link: As an alternative to the browser add-on, click this link to prevent Google Analytics from recording data via this website in future. This will save an opt-out cookie on your device. Note that the opt-out cookie will only work in the browser in which it is set. And if you delete cookies from your browser, you will need to click this link again.

Our security measures are constantly being improved in line with technological developments.

We use Google’s reCAPTCHA service to enhance data security in the transmission of forms on the basis of TransnetBW’s legitimate interest in the prevention of misuse and spam pursuant to Article 6 (1) lit. f GDPR. The service is associated with the sending of IP addresses and, where applicable, other data required by Google for the reCAPTCHA service. The deviating provisions of Google’s Privacy Policy apply.

We expressly encourage parents or guardians to monitor their children’s online activities. Unless they have permission from their parents or guardians, children should not send personal details to us.

User rights and deletion of data

You are entitled to receive, at no cost, information about the personal details about you that are saved in our system as per Art. 15 GDPR. You also have the right to correct inaccurate details (Art. 16 GDPR), to restriction of processing (Art. 18 GDPR), and to deletion of your personal data (Art. 17 GDPR). You may also withdraw any consent at any time with future effect.

If we process your data on the basis of legitimate interests (Art. 6 para 1 (f) GDPR) or to perform a task in the public interest (Art. 6 para 1 (e) GDPR), or if your particular situation gives rise to grounds opposing such processing, you have the right to object to processing of your data in accordance with Art. 21 para 1 GDPR.

Pursuant to Art. 21 paras 2 and 3 GDPR, you have the unrestricted right to object to any form of processing for the purposes of direct marketing.

If there are grounds to assume data is being processed illegally, you are entitled to lodge a complaint with the competent supervisory authority.
