Among the many Advantages of belonging to a large Company Group, sustanability plays an important role across it, particularly evident from the synergies between the individual companies. A classic example is the collaboration established between the R&D Department of LEITWIND and LEITNER (cable Transport systems), which resulted in the Production of the first direct drive LEITWIND wind turbine. Here, the direct drive is used in reverse Operation as a Generator. During the last 16 years, LEITWIND has designed many Generators, with nominal power up to 3MW, installing and commissioning more than 365 wind turbines with the LEITNER DirectDrive.
Now the LEITWIND Team has advised DEMACLENKO, another brand of the High Technology Industries (HTI) Company Group, which deals with the Production and Installation of turnkey snowmaking systems. While for LEITWIND the wind is the key element for being able to produce energy, for DEMACLENKO it is the temperatures and the reliable forecast of the evolution of the weather conditions to assume greater importance, since Windows opportunity for snowmaking are becoming ever Shorter. The R&D Department of LEITWIND has therefore developed in collaboration with DEMACLENKO a meteo-app, which makes it possible to deduce the trend of the wet bulb temperature over the coming ten days to plan snowmaking operations carefully. The forecast is based on current and historic recordings of temperatures and humidity in selected places in the Ski Resort, combined with General weather models (MOS-procedures). It is the most reliable on the market.

LEITWIND will be exhibiting at the ICCI trade Show in Istanbul, Turkey, from the 28th - 30th May. Come and join us at the LEITWIND stand, Hall 9 - stand 105, it would be great to see you!
ICCI is Turkey's biggest event for renewable energy and energy Efficiency industry, which is successfully Held since 1994 and regularly attended by 14,000 visitors.
The first LTW42 turbine was installed on March 15 in Steinfeld, in Schleswig-Holstein (GER), near the Danish boarder. This first LEITWIND-turbine will be followed by a further 49 turbines by the end of 2020.
The first calculations on the plant in Schleswig-Holstein demonstrate that the turbine will supply the customer’s agricultural business in Steinfeld with 660 MWh of self-produced electricity annually with a reduction of CO2 emissions equal to 370 tons.
The turbine uses the well proven and patented LEITWIND DirectDrive technology. The low tower height of 28m allows a simplified authorization process and an installation closer to buildings compared to conventional wind turbine generators. This is an important argument for potential customers to switch to this particularly user-friendly form of green energy in the future.
Another peculiarity of that wind turbine generator is the grid connection concept, which is compatible to grods of low-voltage at 400V and can be directly connected to the distribution unit of the customer. In this way the customer can self-consume the major part of the produced energy without being dependent on intermediary distributors and without being exposed to the varying feed in tariffs of the energy market. These attributes make the turbine especially interesting for small and medium-sized enterprises, which represent the main target group of this product.
For Anton Seeber, CEO of the LEITNER Group, the successful installation of this first plant is already a significant milestone in the more than 15-year history of LEITWIND. “What was particulary impressive is that with this system, we quickly developed a pioneering solution together with our partners in order to produce renewable electricity from wind in an efficient and cost-effective way. We were able to demonstrate once again our strength in Research and Development. We are proud that our company contributes to protecting our environment”, explained Seeber.
In the Greek region of Eastern Macedonia and Thrace, near the Turkish border and the Aegean Sea, the construction of a LEITWIND LTW101 wind turbine, with a hub height of 93.5-metres, has been completed. The supply contract incuded the planning, delivery, installation, and commissioning of the LTW101 turbine on customer Techniki Ergon’s property in Alexandroupolis. The LTW101 3.0 MW is the largest wind turbine generator currently offered by LEITWIND.
The the area surrounding Alexandroupolis, wind turbine generators are not new. However, it is the first installation of the LEIWTIND in Greece. The Greek wind industry has struggled after years of recession, but is now reinvigorated and LEITWIND wants to become an important player.
The project specifications required the construction of a wind turbine with a maximum power output of 2.6 MW. This means that the LTW101 will be able to generate a maximum of 8.3 GWh per year – the equivalent of powering 2,200 Greek households. The quality and high performance of the LTW101 were crucial factors in the selection of a Leitwind wind turbine generator.
The high degree of flexibility and organizational capacities in Leitwind’s produtcs, event for a single installation, played an important role for the customer.
As well as a planned expansion of the project in Alexandroupoli, Leitwind is extending its generators acress the Greek market as a whole, using both small- and medium-sized generators to accommodate for the geography of the Mediterranean country.
LEITWIND specializes in the construction of small wind turbine generators and small wind farms with hundreds of installed wind turbine generators worldwide.
“The project is an expression of our commitment to a greater growth in new markets. With the première in Greece, the company is sending another strong signal,”says Marco Tosi, sales manager at Leitwind.
“We are convinced of the potential of the Greek wind power market and delighted that we have made a successful start with the first turbine. Through this we are continuing the LEITWIND strategy of recent years,” explains Tosi.
Panagiotis Gkiokas, board member of Techniki Ergon SA, the company that installed the LEITWIND wind turbine said:”We chose LEITWIND to be our partner in our first step as they offered competitive pricing, direct-drive technology and, more importantly, met our demand of installing a single turbine in a tight time schedule.”
The wind turbine design differs from all other products on the market. With its big rotor diameter of 42m and the low power output of 250kW, the specific energy reaches a level of 180W/m² which makes the turbine perform perfectly also on sites with very low average wind speeds. The low total height given by the 30m tower allows a simplified permitting process and an installation closer to buildings than for conventional wind turbines.
The turbine uses the well proven and patented LEITWIND DirectDrive Technology similar to the LEITWIND MW-class products, which are installed all over the world. Design assets as active electrical pitch and yaw regulation, control and protection system as of MW class turbines, LEITNER DirectDrive generator and the LEITNER full power IGBT power converter LeitDrive make the turbine an avant-garde product in its class.
The turbine´s most specific asset is however its grid connection concept. The turbine connects to a 400V low-voltage grid, directly to the dispatching unit of the customer. So the major part of the produced energy will be used in own-consumption by the customer itself what increases highly its profitability and makes it independent from public feed in tariffs. These attributes make the turbine especially interesting for small and medium-sized enterprises, which present the main target group of this product.
The first prototype of the turbine will be installed in fall 2018 on a site in the south of Germany. b.ventus offers a complete package including permitting, construction, grid connection, maintenance and insurance for the 250kW turbine. To produce his own green energy the customer has nothing to do except to commission b.ventus. In Germany, customers benefit twice: as a self-sufficient consumer - in terms of self-consumption – their energy consumption is exempted from the feed-in tariffs by means of renewable energies.
b.ventus business concept is a perfect fit for LEITWIND's strategy, as wind turbines must be able to connect to the local energy network, as well as offering high efficiency. The power is supposed to be available directly, without needing to transport the electricity from one place to another. That avoids high infrastructure costs and network losses.
