In China, the tidal range energy is mainly concentrated in
two coastal provinces, Zhejiang and Fujian, accounting for
about 90% of the total.
Zhoushan
The tidal current energy resources of China is most abundant in
Zhejiang coastal area, amounting to about 5.17 million kilowatts
( 5.17GW), and accounting for more than half of the total
nationwide potential tidal current energy resources, which is
mainly concentrated in the estuary of Hangzhou Bay and
Zhoushan Islands.
The wave energy resources in China are most abundant in
Guangdong coastal area, the next are Fujian, Zhejiang,
Hainan and Shandong, accounting for 90% of the total.
2. Characteristics of ocean energy resources in Zhoushan
Status of ocean energy resources in Zhoushan
 Tidal Range Energy:The average tidal range in Zhoushan sea area is about 2m only, island and harbor
area is small and many harbors have been developed into ports, docks, there are few bays suitable for tidal
energy development, therefore, the area is slenderly endowed with tidal energy resources as a whole.
 Tidal Current Energy: The waterways in Zhoushan sea area is crisscross, the flow velocity of tidal
current is big, the maximum flow velocity in waterway of several areas is 2.0-3.0m/s, and over 4.0m/s at
most in partial areas, so it is an area rich in tidal current energy resources, and with most advantageous
tidal current energy resource conditions among Chinese coastal areas.
 Wave Energy: Zhoushan sea area close to the East China Sea is a large wave zone along the coast of
China, the long-period wave can go into this area. The sea area inside of the islands is shielded by islands,
the wave height is smaller; the wave height is big in the open sea area in the east of the islands, average
annual wave power density is more than 2.5kW/m, so the wave resources are abundant.
To sum up, full use of unique advantages of the area such as concentration of ocean energy resources,
convenient transportation and prosperous marine equipment manufacture industry to exploit and utilization
clean marine renewable energy will be one of the effective means to promote energy structure
transformation and drive the development of emerging marine industry in Zhoushan Islands District.
