Production analysis

The above figure shows the concurrent monthly production data and monthly Windex Windunie “Noord Holland Noord” data over a number of years per turbine. The Windex from Windunie is a well-known Windex in the Netherlands. The reference period of this Windex is from 1996 until 2005.

The above figure shows the monthly production data and the monthly Windex Windunie “Noord Holland Noord” data in a scatter plot. The trend line is the closest match between all points and the R2 represents the correlation factor. If R2 is 1 the data shows a perfect match and from 0,8 it is considered as a good correlation.

Site Overview

Site is similar to picture above (picture of neighbouring park). Drawing available upon request.

Vestas Requiremants - Terrain & Climatic ConditionsIf the terrain within a 100 m radius of the turbine has a slope of more than 10° (18%), particular considerations have to be taken.

The turbine is designed for ambient temperature ranging from -20°C to +40°C. Outside these temperatures the turbine stops, and special considerations must be taken.

With regards to the wind conditions the turbine has been designed in accordance with IEC 1400-1 class I, DS472 (Teknisk Grundlag), Germanischer Lloyd of 1993, class II and NEN 6996/2, Den Helder.

The turbines can be placed in wind farms with a distance of min. 5 rotor diameters (330 m) between turbines. If the turbines are placed in one row, along predominant wind direction, the distance between the turbines must as a min. be 4 rotor diameters (264 m).

Operation & MaintenanceAll assets are maintained according to Vattenfall standards, following the original maintenance manual, by the Original Equipment Manufacturer or a third-party contractor. Maintenance manual, maintenance history are available during site visit. As-built documentation is available upon request.
