About Us

Geschäftsführer Dipl. Ing. (FH) Dietmar Tietz

Energy is a fundamental physical variable, it can neither be generated nor destroyed, it can only be transformed.

Energy conversion is the speciality of WT Energiesysteme GmbH. We are medium-sized company with our headquarters in Riesa and Dresden. Our core competence lies in the construction, maintenance and modernisation of transformer stations or grid feeds – with an output that ranges from 10 to 380 kV.

During the realisation of our projects, we attach particular importance to adherence to delivery dates and cost reliability. The construction of a transformer station is always a major project, which makes it all the more important for us to work together very closely. The following is very important here: Our customers are always also our partners.

WT Energiesysteme


WT Energiesysteme GmbH, with its headquarters in Riesa, has constructed numerous electrotechnical plants in recent years.

Our areas of expertise are the implementation of customer-specific requirements for the efficient feeding in and connection of high and medium voltage systems in the field of regenerative energy production. In addition, we realise the connection of electrotechnical plants of industrial companies. An additional priority area is the construction of transformer stations for energy supply companies. In doing so, we back manufacturer-independent and pioneering solutions both in terms of the use of system components as well as in the areas of monitoring and system protection.

Our company offers you the entire service catalogue from one source. You have a contact in us that works with you to develop turnkey solutions that meet your individual requirements.

Experienced engineering and assembly teams realise your goals efficiently, quickly and cost-effectively. Here we as a company assume the entire responsibility for the projects that have been jointly developed. Safety and occupational safety are important issues for us. We therefore attach great importance to the annual training courses on occupational safety and occupational health care for all employees. In addition, the training sessions are supplemented by monthly briefings on current topics in order to always keep their awareness of safety, health and the environment at a high level.

We always keep our employees up to date with technological developments. We develop a protection concept for every project. We monitor the protective settings of the plant and ensure the parameterisation of the corresponding protective devices.
