BYSTRUP is the designer behind the Composite Pylon. The firm has been involved with infrastructure design and power pylon design for the past 20 years and have had designs realized in Denmark and the United Kingdom. 


Bystrup is a global consultancy adding value to public and private clients on next-generation architecture and design all over the world. Bystrup was originally founded as a broadly focused architecture firm in 1994 but redefined as an architect and engineering firm in 2009. Today, the company is primarily involved in infrastructure related projects. Bystrup is owned by Founder Erik Bystrup and CEO Henrik Skouboe.


Bystrup has been working on the design of new high voltage pylons for over 15 years. Bystrup holds a thorough knowledge of what is happening on the development front in the high-voltage pylons throughout Europe and worldwide and also has a wide component manufacturer network. Bystrup is primarily dedicated to the design, development and optimization of high voltage pylon solutions for Transmission System Operators (TSOs), and has participated in several international design competitions, winning prices for their innovative new OHTL pylon design. 


Bystrup's work encompasses the complete overhead line design including foundation and routing. 

In collaboration with the Danish operator Energinet, Bystrup have previously developed the new 1x400 kV Design pylon made of steel, which is now installed on a 25 km line in North Jutland, Denmark. 


Later, a 2 x400kV Design pylon (the Eagle Pylon) has been developed and is being used for the construction of a 180 km OHTL in Southern Jutland, (to be expanded in 2020). 
Bystrup won another OHTL design competition in England with the "T-pylon" design (also in steel), where the first prototypes have been through a comprehensive testing program, and where the T-pylon is planned for different OHTLs in the UK.
