The 3rd-generation LHD horizontal axis modular generator set was successfully installed offshore on Saturday in Zhoushan, east China's Zhejiang Province. It marked the commissioning installed LHD tidal power capacity reaching 1.7 megawatts, which makes it a leader across the world.
China's farthest offshore wind farm is being built in the Yellow Sea off the coast of eastern China's Yancheng City. The farm is scheduled to be completed by the end of November and it is expected to generate 870 million kwh of electricity per year.
