TÜV NORD has prepared an energy yield assessment for one of the first large wind farms in the Philippines for the Bremen-based project developer and operator of wind and solar farms wpd and cooperation partner Triconti ECC Renewables Corporation. The AEP report (annual energy production) is very important for the planning of a wind farm in order to estimate the wind conditions at the planned site and to calculate the expected energy yields. Site assessment experts from TÜV NORD GROUP in Hamburg and Athens worked closely together to produce the technically demanding report for the project.
The Aklan wind farm is being built in a hilly area on the north-western tip of Panay Island at an altitude of between 123 meters to 362 meters above sea level. According to wpd, commissioning is scheduled for the end of 2025 or the beginning of 2026.
As the wind-farm area is considered a complex terrain according to IEC classification, CFD (Computational Fluid Dynamics) modeling was carried out for the project by wind-energy experts in Athens. The results of this flow modeling were then used for further calculations in Hamburg.
The yield assessment was based on wind measurements that wpd and its cooperation partner Triconti ECC had previously collected at the planned site using several measuring masts and Lidar devices. The combination of two measurement methods and also the correlation among the data sets enabled a comprehensive picture of the wind conditions in the challenging terrain. With these evaluations and the CFD modeling, the Hamburg site assessment experts of TÜV NORD determined the wind potential at the respective locations of the planned wind turbines and thus predicted the expected energy yield.
