Wind power growth makes it essential to simulate weather variability and its impacts on the electricity grid. Low-probability, high-impact weather events such as a wind drought are important but difficult to iden-tify based on limited historical datasets. A stochastic weather generator, Imperial College Weather Genera-tor (IMAGE), is employed to identify extreme events through long-period simulations. IMAGE captures mean, spatial correlation and seasonality in wind speed and estimates return periods of extreme wind events over India. Simulations show that when Rajasthan ex-periences wind drought, southern India continues to have wind, and vice versa. Regional grid-scale wind droughts could be avoided if grids are strongly inter-connected across the country.
