Peter Kelemen, an experienced engineer from Salzgitter with many years of expertise in large steel structures, has explored how know-how from the steel industry can also be applied to foundation and tower structures in the wind energy sector. In doing so, he has repeatedly developed compelling ideas for innovative support structures for wind turbines.
We recognized the potential of these ideas and have already carried out feasibility studies based on real turbine data.
In close collaboration with Peter Kelemen, these concepts are now being further developed under the K-Tower Systems label. In this process, we draw on many years of experience in the development and structural verification of support structures, enabling us to transform initial design ideas into feasible, buildable solutions.

K-TowerGiant
Wind energy at new heights!
Wind energy has made significant progress, but conventional onshore systems are increasingly reaching their technical limits. A forward-looking approach is the utilization of stronger winds and higher altitude. A feasibility study by P. E. Concepts GmbH and K-Tower Systems GbR shows that wind turbines with hub heights of 220 to 300 meters can significantly increase energy yield. With innovative, modular tower designs such as the ‘K-TowerGiant,‘ this vision can be realized economically, sustainably, and using proven technologies.
What benefits does this concept offer you?
- Greater hub height enables higher energy yield
- Construction using standard steel products
- Compact design with minimal space requirements
- Installation using conventional and proven climbing cranes
- Use of four ‘small‘ individual foundations
- Internal components similar to those in standard towers

K-TowerRe
Uplifting for your towers and systems!
With the K-TowerRe, existing wind turbines can be efficiently modernized or extended to greater heights. Existing tower structures and foundations are partially reused and supplemented with new components such as pylons and tower segments.
There are two main use cases:
- Turbine height increase: An existing, high-performance turbine is raised to a significantly greater hub height by extending the tower, without completely rebuilding.
- Turbine repowering: Old turbines are replaced, while parts of the existing infrastructure are integrated to significantly reduce costs and construction time.
The process enables an economical and sustainable increase in energy yield while simultaneously reducing construction effort.
What benefits does this concept offer you?
- Significant cost savings and resource conservation through reuse of tower sections and foundations
- Reduced material requirements for new components
- Lower logistics and transportation costs
- Use of existing infrastructure (access roads, grid connection, construction areas)
- Modular construction principle with pylons and tower extensions
- No need for complex pre-assembly areas for large cranes
- Flexible adaptation to different turbine classes and heights
- Significantly shorter construction time due to partial reuse and optimized construction processes
- Faster commissioning compared to a completely new build
- Less impact on soil and surroundings
- Alternative to complete site restoration and redevelopment
