Max Bögl Wind AG releases the next generation of its Hybrid Tower system that brings the new high-performance turbine generators up to the hub heights dictated by the market and makes hybrid tower construction even more cost-effective.

They are already higher and generally more efficient than alternative tower designs. The Hybrid Towers of Max Bögl Wind AG combine concrete and steel and allow hub heights of up to 190 meters. The company has now developed the 2.0 version of its Hybrid Tower, which requires less material while still ensuring the highest stability. The new system is even more cost-effective due to changes to the foundation and interior construction and the revised segmentation and geometry of the towers.

Innovative power for more cost efficiency

The new foundation design simplifies pre-tensioning at the input level of the wind turbine and thus streamlines operation. Higher fatigue strengths are achieved and stress peaks in the structure are further reduced. With the conical shape of Hybrid Towers mb 2.0, less tendons are necessary by optimizing the load transference. The interior will now be constructed using a new procedure patented by the Max Bögl Group in which the lift and ladder are mounted during concrete tower erection. Due to the parallel installation process, assembly time is significantly reduced. Company engineers also focused on logistics and transport: In the future almost no heavy lifting devices will be necessary to transport the individual tower segments. Any standard truck can be used, which means wind turbines can now be erected in a far more flexible, faster and safer way.

Hybrid Tower 2.0 paves the way to a successful energy transition

“The market demands more cost-effective wind turbines to meet the new challenges created by the Renewable Energy Sources Act (EEG 2017). Turbine technology is becoming more powerful and rotors are constantly getting bigger and heavier,” says Josef Knitl, CEO of the Max Bögl Wind AG. “Our Hybrid Tower 2.0 is capable of meeting both structural as well as economic requirements. This allows for the continued expansion of renewable energies under the new market conditions.” To this end Max Bögl AG is developing customer-specific tower designs based on the hybrid tower 2.0 for the next generation of turbine generators.

Recently, the high-power wind turbine developed by CRRC for the complex climate and unique geological conditions of Northwest China rolled off the production line and entered mass production at CRRC Baiyin New Energy Equipment Base. This marks an important milestone of CRRC’s presence in the new energy industry in Baiyin.

The 7.5 MW high-power wind turbine offers flexible power configurations ranging from 6.X to 8.X MW and features a rotor diameter of over 220 meters. By incorporating the high-speed train reliability design principles, it not only improves the wind energy capture efficiency, but also ensures safe and stable operation in the complex and variable climate conditions. The wind turbine is the result of CRRC Shandong Wind Power Co., Ltd.’s indepth research into the wind resources and geographical features of Northwest China, particularly in provinces like Gansu.

The first phase of CRRC Baiyin New Energy Equipment Base has been built into a modern industrial cluster centered on wind turbine sets, hydrogen production equipment, and electrical systems, providing a mass production capacity of 300 wind turbine sets and hubs per year.

A strategic step that strengthens LEITWIND’s presence in the Eastern Thrace region.

LEITWIND is pleased to announce the renewed collaboration with its Turkish customer, who had already placed trust in the brand’s products and services in 2023 by choosing LEITWIND for the installation of a 1,500 kW wind turbine. In December 2024, the agreement was formalized for the supply of an LTW90 2,000 kW turbine, which will be installed in the spring of 2026 in Kırklareli province, Eastern Thrace. Equipped with a 97.5-meter-high tower, this turbine represents a significant milestone for LEITWIND in the Turkish wind energy market.

LEITWIND’s success in Turkey can be attributed to several factors: the adoption of cutting-edge technology, the offer of
a comprehensive all-inclusive package that includes not only the standard supply of wind turbines but also continuous support throughout all project phases, and a strong local presence. Following the establishment of LEITNER TURKEY in May 2012, specializing in the ropeway sector, the LEITWIND TURKEY branch was inaugurated in Bursa, actively managing the 10 LEITWIND wind farms currently operating in the country.

Not only in Turkey but also in Italy, the LTW90 product continues to receive significant recognition. In the fall of 2024, LEITWIND successfully completed the first LTW90 wind farm in the province of Trapani. This project, consisting of three LTW90 with a rated power of 1,000 kW, presented a significant logistical challenge due to the area’s unique morphological characteristics. However, achieving this result highlights the company’s experience and expertise in handling installations in complex environments.

The wind energy sector is undergoing a transformation, with major manufacturers shifting towards turbines with larger rotors and higher power outputs, thereby reducing the availability of Megawatt- class turbines. In this challenging context, LEITWIND stands out for its specialization in small to medium-sized projects and repowering operations, reinforcing its role as a key partner for communities, SMEs, and local investors.

Despite regulatory and permitting uncertainties, the small to medium-sized wind energy sector represents a strategic opportunity to enhance the value of already installed energy potential. LEITWIND is ready to further strengthen its leadership position, making a significant contribution to the global energy transition.

Since its establishment in 1984, ENERCON has pioneered in wind energy technology by developing onshore wind turbines and playing a key role in the industry. With over 33,000 installed wind turbines worldwide and a cumulative installed capacity exceeding 64 GW, the company stands as one of the architects of a sustainable future. It has established itself as one of the leading brands in the global wind energy sector by means of its innovative wind turbine technology, high-quality standards, and decades of experience. In Türkiye, it is recognized as one of the pioneers of the country’s energy transition. As Türkiye’s first wind turbine brand, ENERCON Türkiye has achieved many industry milestones throughout its 27-year history. Today, with more than 1,250wind turbines installed, the company alone accounts for nearly 24% of Türkiye’s total 13 GW installed wind capacity.

The company entered the Turkish market in 1997 and has since exceeded a cumulative installed capacity of 3 GW, starting from just 1.5 MW, marking a significant milestone in its journey. By the end of 2025, it aims to achieve a total installed capacity of 4 GW. As the turbine supplier for the 1,000 MW mega project encompassing the entire YEKA RES-2 tenders, the company continues to play a key role in Türkiye’s energy transition through its contracts in YEKA-2 and YEKA-3.

The company is solidifying its role in Türkiye’s wind energy sector with ongoing and contracted projects. Rather than seeing Türkiye merely as a sales market, it actively engages in production and engineering activities. Through its investments in education and R&D, ENERCON contributes to developing innovative wind energy technologies in the country. As part of its collaboration with Enerjisa Üretim, ENERCON is set to test the E-175 EP5 model—one of the world’s largest wind turbines with a rotor diameter of 175 meters—for the first time in Türkiye at the Bandırma Energy Hub. The E-175 EP5 E2 7 MW stands out as one of ENERCON’s latest and most advanced turbine designs in engineering. ENERCON’s signature direct drive technology distinguishes the company from other brands and is also a key feature in this model. Additionally, incorporating a permanent magnet system maximizes energy efficiency, demonstrating its commitment to high performance. With its robust performance and optimized aerodynamic design, the E-175 EP5 E2 ensures maximum energy generation even at low and medium wind speeds, reflecting ENERCON’s sustainability and technology-driven vision.
