Some thoughts about the quality of the wind data used:
The ECMWF data used for the calculation of wind potentials and also used to provide time series of the potential wind energy production for the scenarios tend to significantly underestimate the conditions in mountainous terrain. This can be shown on a huge variety of locations worldwide. One of the most significant underestimations of the wind energy potentials is known in the area around the Gulf of Suez. Here the best locations might deliver almost three times the amount of electricity compared to the calculations based on the ECMWF data.
This will be shown in the following slides.
The very conservative ECMWF data therefore also lead to very conservative scenarios. This has to be consider while evaluating the results of the scenarios. They therefore tend to be something like a worst case estimation. The real conditions will be better and therefore the electricity might be provided significantly cheaper.
