SIEMENS GAMESA 5.X PLATFORM SELECTED FOR THE SKAFTASEN PROJECT IN SWEDEN

Siemens Gamesa is launching a new era for wind power with a deal to supply the most powerful geared onshore wind turbine ever, the SG 5.8-155 wind turbine. The first of the 35 units, all with flexible power rating operating at 6.6 MW, will be installed in the second quarter of 2021 in the Skaftåsen project in Sweden, the first in the world to feature the Siemens Gamesa 5.X platform.
Project developer Arise AB and leading infrastructure investment manager Foresight Group have chosen this latest generation of onshore turbines due to its strong performance and advanced design, combining reliability with maximum Annual Energy Production (AEP) for the lowest LCoE. With a 30-year full-service agreement, this new generation of onshore wind turbines will generate predictable revenue streams over its lifecycle, improving the business case of the project.
The 231 MW order marks the debut of the Siemens Gamesa 5.X platform, only months after its presentation in April 2019, during WindEurope Bilbao trade fair. Additionally, the debut of the Siemens Gamesa 5.X in one of the world’s most sophisticated wind markets highlights the superior performance of a platform developed by an engineering team bringing together the best technologies for use in a wide range of markets and requirements.
Siemens Gamesa 5.X goes one step further to become the new generation platform with the biggest unitary power on the market and the largest rotor diameters, 155 and 170 meters, resulting in maximum performance in high-, medium and low-wind conditions. Both turbines mean greater AEP per wind turbine and optimized project CAPEX.
To adapt successfully to temperatures that can reach -15º C in Fågelsjö, where the turbines will be installed, they will be delivered in the cold climate version of the platform, capable of withstanding -40°C and operating at temperatures as low as -30°C. The turbines will feature the STC, a turbine control software system also used for Siemens Gamesa offshore products, meaning that all enhancements can be transferred, facilitating the work of the service technicians.
The project was developed by Arise AB, one of Sweden’s leading developers. The project has been acquired by funds managed by Foresight, a leading UK-based renewable energy infrastructure investor.
