Norwegians to be advisors on wind substation in China

Energy experts from Norway has been contracted to provide technical advisory support on feasibility studies for offshore wind substation in China.

Norwegian DNV GL, the world’s largest resource of independent energy experts and certification body, will provide technical advisory support on feasibility studies for the first-ever Chinese high-voltage direct current (HVDC) offshore wind substation.

China has committed heavily to developing its offshore wind power generating capacity. But the country is now faced by the challenge that all the promising wind farm sites within 10 km of the shore have already been exploited. Therefore, China has to explore locations that are further offshore.

Chinese Huadong Engineering Corporation is planning for the offshore wind farm to be located some 90km off the coast of Jiangsu Province.

Traditional submarine high-voltage alternating current (HVAC) cables become extremely inefficient when transporting large amounts of electricity over such long distances. In contrast, high-voltage direct current (HVDC) systems allow power to be transmitted over large distances under the sea with minimal losses.
