Renewable Energy


I am a certified electrician. After the move to a cable manufacturer (2003) I worked until 2007 in the field of mobile radio and fiber optic cable technology.

In 2008-2012 the main focus of the company was the construction and maintenance of solar power plants. In the beginning my function was construction manager and then project manager.

From 2012, the business field shifted to the area of high-voltage cable systems onshore and medium-voltage cable systems offshore. During this time I held the position of Senior Project Manager, where I was also directly responsible for various projects as Project Manager.

Revocation of your consent to data processing
Many data processing operations are only possible with your express consent. You can revoke your consent at any time. For this purpose, an informal e-mail notification to us is sufficient. The legality of the data processing carried out until the revocation remains unaffected by the revocation.

Right of appeal to the competent supervisory authority
In the event of breaches of data protection law, the data subject shall have the right to lodge a complaint with the competent supervisory authority. The responsible supervisory authority for data protection issues is the data protection officer of the federal state in which our company is based.

You have the right to have data which we process automatically on the basis of your consent or in fulfilment of a contract handed over to you or to a third party in a common, machine-readable format. If you request the direct transfer of the data to another responsible person, this will only be done as far as it is technically feasible.

SSL or TLS encryption

Cookies are small text files that are stored on your computer by your browser. Most of the cookies we use are so-called session cookies. They are automatically deleted at the end of your visit. Other cookies remain stored on your end device until you delete them. These cookies enable us to recognize your browser during your next visit. You can set your browser so that you are informed about the setting of cookies and only allow cookies in individual cases, accept cookies for certain cases or generally exclude them and activate the automatic deletion of cookies when closing the browser. If cookies are deactivated, the functionality of this website may be restricted. Cookies which are necessary for the electronic communication process or for the provision of certain functions requested by you (e.g. shopping basket function) are stored on the basis of Art. 6 para. 1 lit. f DSGVO. The website operator has a justified interest in the storage of cookies for the technically error-free and optimised provision of its services. Insofar as other cookies (e.g. cookies for analysing your surfing behaviour) are stored, these are dealt with separately in this data protection declaration.

Server log files
The provider of the pages automatically collects and stores information in so-called server log files, which your browser automatically transmits to us. These are: - Browser type and browser version - operating system used - referrer URL - host name of the accessing computer - time of server request - IP address This data is not merged with other data sources. The basis for data processing is Art. 6 Para. 1 lit. f DSGVO, which permits the processing of data to fulfil a contract or pre-contractual measures.

Contact form
If you send us enquiries via the contact form, your details from the enquiry form including the contact data you provided there will be stored by us for the purpose of processing the enquiry and in the event of follow-up questions. These data will not be passed on without your consent. The processing of the data entered in the contact form is therefore carried out exclusively on the basis of your consent (Art. 6 para. 1 lit. a DSGVO). You can revoke this consent at any time. For this purpose, an informal e-mail notification to us is sufficient. The legality of the data processing operations carried out until the revocation remains unaffected by the revocation.

Mandatory legal provisions - in particular retention periods - remain unaffected.

When calling up the respective social networks and platforms, the terms and conditions and data processing guidelines of their respective operators apply. If users contact us via the chat, comment or message function of social networks and platforms, we process this information for communication purposes. Basis for the data processing is your voluntary transmission of the data according to art. 6 para. 1 lit. a DSGVO. You can revoke this consent at any time.
