Electricity from a European onshore wind farm using SG 6.2-170 / 6.6-170 wind turbines

The new Siemens Gamesa 5.X onshore platform has its roots in Siemens Gamesa technology, synonymous with innovation, know-how and reliability accredited through experience. Siemens Gamesa 5.X incorporates proven technologies, minimizing risk and guaranteeing reliability for its two new product models: SG 6.6-155 and SG 6.6-170 wind turbines. These include a doubly-fed generator and partial converter combination, a compact drive train design with a three-stage gearbox, and the use of components widely validated on the other Siemens Gamesa platforms. The result is a wind turbine design that gives optimum performance and LCoE.

Siemens Gamesa 5.X goes one step further to become the new generation platform that combines a flexible power rating from 5.6 MW to 6.6 MW with two of the largest rotor diameters in the market, 155 and 170 meters, resulting in maximum performance in high-, medium- and low-wind conditions.

SG 6.2-170 and 6.6-170 turbines mean greater AEP per wind turbine and optimized CAPEX for the project. This is also due to their versatility, with a modular, flexible design for maximum ease of logistics, construction and O&M, as well as reducing the OPEX, which results in a lower Cost of Energy for projects. For the present LCA, a life cycle model has been created, using 115 m high towers.
