Saudi Arabia’s energy portfolio has historically been dominated by fossil fuels due to their abundance in the country. However the country is currently investing significant research efforts for the development of technologies to harness alternative, renewable energy sources to meet the increasing demands resulting from Saudi Arabia’s economic growth and population increase expected over the next decades. Recent studies, based on coarse climate model simulations and in-situ measurements, have indicated that wind resources are naturally abundant in Saudi Arabia, especially in its mountain and coastal regions. Here we present the first ensemble of high-resolution simulations of the Weather and Research Forecasting (WRF) model performed over the region to quantify wind energy potential. Simulated wind speeds are evaluated against a range of observations to identify model settings that allow optimal representation of wind fields. In the next phase of the project, computationally affordable stochastic generators will be developed to generate additional runs, in order to quantify the uncertainty in wind power estimates, which is a critical component for a wind farm feasibility study.
