New 120 m Hybrid Steel Tower makes E175 EP5 E2 installation possible in ENERCON’s home region.
As part of ENERCON’s identity as a provider of solutions for the connected energy ecosystem, it is essential to remove obstacles that stand in the way of successfully implementing customer projects. In some regions, for example, there are complex height and distance limitations that prevent the use of standard towers from the product portfolio. Thanks to ENERCON’s flexible tower development, customers in such cases – assuming a positive economic assessment – can rely on competitive alternatives, as demonstrated by the example of the new 120meter hybrid steel tower for the flagship E175 EP5 E2 model.
The ‘Ostfriesland Tower’ was developed to meet the specific requirements of customers in ENERCON’s home region. Due to restrictive specifications from the German armed forces related to airspace surveillance along the coast, wind turbines around ENERCON’s headquarters may not exceed a maximum height (‘tip height’) of 218 meters above sea level. In addition, for nature conservation reasons, the distance between ground level and the lower blade tip position (‘lower tip height’) may not be less than 30 meters for new turbines – otherwise significant yield reducing shutdown periods may apply.
These specific requirements cannot be met by the standard towers of the E175 EP5 E2. An alternative solution was therefore needed. ‘We are talking about roughly 60 new turbines that we want to implement together with our customers in our home region,’ says Moritz Rodenhausen, Head of Product Management. ‘This scale ensures a positive business case for us as a manufacturer as well. Thanks to our flexible tower development, a rapid project specific tower design was completed and the “Ostfriesland Tower” was developed.’175 EP5 E2.

This tower is based on ENERCON’s hybrid steel tower technology, combining segments of the Modular Steel Tower (MST) – made of bolted, bent steel plates – with segments of a tubular steel tower (ST). It has a hub height of 120 meters. With this tower variant, the E175 EP5 E2 fits precisely within the height and distance restrictions defined by military radar and nature conservation requirements for Ostfriesland.
‘We are pleased to offer our local customers options that allow them to begin detailed planning of their wind farm projects,’ says Moritz Rodenhausen. ‘Our tower development team has further optimized and significantly accelerated its processes. This allows us to react even more agilely and flexibly to specific customer requirements.’
But the new HST tower will not be limited to the Ostfriesland region: ‘Since we are obtaining certification for the new tower according to IEC and DIBt standards, we automatically meet the certification requirements in many European countries – for example, the UK, Italy, Turkey, the Baltic states, Poland, Romania, Portugal, Austria, the Netherlands, Luxembourg, Greece, and Ireland,’ says Maria-Josefa Brand, Tower Product Manager in ENERCON Product Management. ‘The “Ostfriesland Tower” will therefore also enable customers in other market regions to realize their onshore projects with our flagship model in the future.’
As a provider of integrated solutions for the connected Green Energy Ecosystem, ENERCON supports its customers in the realization of onshore wind energy projects. To fully unlock project potential, the company combines its high-performance, high-yield wind turbines with complementary solution components and services, enhancing customer benefits and the overall value of wind energy. The range of the solution portfolio, from which customers can select modules according to their requirements, extends from planning and installation to management and control, service and maintenance, and optimisation of system performance during the operational phase.
As a pioneer in renewable energy with over 40 years of experience and a deep understanding of the demands of a changing energy system, ENERCON’s scope has always extended beyond mere wind turbines. With the mission ‘Energy for the World’, the company has been committed to sustainable energy generation from onshore wind since 1984. Thanks to its innovative turbine technology, high quality standards, and an installed total capacity of more than 65 gigawatts, ENERCON is among the world’s leading renewable energy companies.
With extensive expertise in the area of ‘holistic project development’, ‘connected operation’, and ‘smart optimisation’, a dense service network, and a broad network of partners and service providers, ENERCON is a competent and reliable partner for its customers in all project phases. Headquartered in Aurich, Lower Saxony, the company employs around 13,000 people at administrative, sales, production, and service locations worldwide.

ENERCON and logistics partner Rhenus are using the new, innovative push barge “Rhenus Berlin I” for the first time to transport wind turbine components via inland waterways. Last weekend, steel tower sections for ENERCON wind turbines of types E-138 EP3 and E-115 EP3 were loaded onto the 100-metre-long vessel at the Port of Emden.
The two companies will continue their collaboration in the future. The industry pioneers have now extended their partnership and signed a new framework agreement for their cooperation.
