The Nordex Group is extending its range of Delta4000 turbines for the North American market to include a variant of the
N155/4.X turbine on concrete towers for specific sites.
John McComas, CEO Nordex USA: “Nordex is committed to working along with our clients collaboratively in order to find unique product solutions in order to increase project suitability, investment, and ultimately return.” And he adds: “Up to 20 percent of the total costs of a wind turbine is accounted for by the tower. At specific sites, concrete towers can be an option to reduce project costs. We are now also offering our N155/4.X turbine in the Delta4000 series on concrete towers with a hub height of 120 metres for selected sites in the USA, like in Texas.”
The Nordex Group is currently building projects comprising more than 400 MW with N155/4.X turbines on concrete towers in Spain and Mexico. A first project with Nordex turbines on concrete towers in the US is the 209.4 MW “Reloj del Sol wind farm”, owned and operated by EDP Renewables North America, near San Ygnacio in the south of Texas. It comprises 40 AW132/3465 turbines, 17 AW132/3000s and six AW132/3300s, all installed on concrete towers with hub heights of 120 metres.
The Nordex Group can look back on 15 years of experience in the manufacture of concrete towers. The concrete towers consist of 20 metre prefabricated convex segments, which are assembled on site when the turbines are installed in the wind farms. As of today, the Nordex Group has sold more than 1,900 turbines with Nordex concrete towers worldwide.
