Landmark order for 231 MW onshore wind project in Sweden

Siemens Gamesa has launched a deal to supply its new the most powerful geared SG 5.8-155 onshore 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 at the 231 MW Skaftåsen project in Sweden, the first in the world to feature the Siemens Gamesa 5.X platform.

Project developer Arise AB and Foresight Group LLP 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.

Siemens Gamesa 5.X has 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. This is also due to improved 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.

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 and has recently been acquired by funds managed by Foresight.
