In view of the development trend of coal demand in China’s coastal area, this paper analyzes the development of coal demand of Zhejiang province, the service target of Ningbo-Zhoushan port coal transport.According to the analysis of the current situation of energy consumption, coal consumption and transport structure of Zhejiang province, this paper forecasts the energy and coal consumption demand of Zhejiang province in 2015 and 2020 and estimates the coal transport mode and structure, and thus obtains the development trend of coal throughput of Ningbo-Zhoushan port. Combining with the situations of the existed coal berths and those under construction, this paper also discusses the adaptability of port throughput and wharf capacity.
