Assessment of long-term offshore wind energy potential in the south and southeast coasts of China based on a 55-year dataset

In this study, based on the Japanese 55-year Reanalysis (JRA-55) dataset, spatio-temporal variations of wind resources were analyzed in South China Sea. An approach to determine suitable locations offshore energy extraction was proposed and applied south southeast coasts China. The took into account various criteria, including long-term change wave condition, with different weights. results showed that Luzon Strait Taiwan have higher potential than other areas, while intra-annual fluctuation is significantly high, ranging from 400 2500 W/m2 thus it not provide stable power output. investigation most Sea experienced a remarkable decrease period 1971–1980, overall trend during five decades mostly even. selected sites indicated location for exploitation nearshore Quanzhou, Fujian, near which there are farms under construction, already. suggested future development along Hong Kong, generating 35.36 MWh/y per turbine type SWT-7.0-154.
