Ventotec signs framework agreement for at least 200 Siemens wind turbines

German wind power plant project developer Ventotec GmbH is looking to work closely with Siemens. At WindEnergy Hamburg 2016, the firm, headquartered at Leer in East Friesland, signed a framework agreement for the supply of at least 200 Siemens direct-drive wind turbines.

The turbines will be deployed in a number of current and upcoming onshore projects being planned by Ventotec across Germany. In addition, Siemens will service the turbines on behalf of Ventotec under a 20-year full-scope maintenance agreement.

Under the agreement, Siemens will supply at least 35 units to Ventotec per year, enabling around 40 new wind farms to be built over the next eight years, notably in the German states of Mecklenburg-West Pomerania, Saxony, Saxony-Anhalt, Brandenburg and Thuringia. Siemens’ current direct-drive wind turbines offer rotor configurations and hub heights to cover a wide range of site conditions, and can also be configured for special requirements. This allows noise abatement regulations and, in particular, grid requirements (relating, for example, to bat protection or deicing) to be met.

“Siemens, with its state-of-the-art systems and equipment, is an ideal partner for us,” said Ventotec’s joint managing directors Helmer Stecker and Ralf Heinen. “As we are always looking to develop new projects, we need mature technology that can be supplied to our wind farms on an ongoing basis. This framework agreement allows us to implement our projects within short planning lead times, and gives us continuous access to optimally adapted wind turbines.”

“We are looking forward to the close, long-term collaboration that this agreement will bring”, said Thomas Richterich, CEO Onshore of Siemens’ Wind Power and Renewables Division. “As an experienced company with expertise that spans the entire spectrum from project design through licensing to construction and operation of wind farms, Ventotec is a key player in the German market.”
