Jiangsu Province is one of the planned strategic areas for wind power development in China, but its current development of wind power industry is not so outstanding. Since, Jiangsu would encounter little market resistance, this paper focuses on the evaluation of resource capacity for wind power development in Jiangsu Province, including the wind energy capacity, land resources capacity and power grid capacity, in order to find their supportive or restrictive effects on the development of wind power industry. The results show that the wind energy resource in Jiangsu Province are sufficient to meet the needs of the development of wind farms; the extensive mudflat in the coastal areas also provides ideal site conditions for wind farms; but the power grid capacity is insufficient for the wind power development in Jiangsu. Therefore, from the aspect of enhancing the capacity of power grid for carrying wind power and from the other aspect of combining the non-grid-connected utilization and the large-scale storage of wind power, this paper suggests some strategies to overcome the constraints of grid capacity and promoting the wind power development in Jiangsu Province.
