Abstract
Adequate recognition of offshore wind energy potential may have far-reaching
influence on the development of future energy strategies. This study aims to
investigate available offshore wind energy resource in China’s exclusive
economic zones (EEZs) with the aid of a Geographical Information System
(GIS), which allows the influence of technical, spatial and economic
constraints on raw offshore wind potential being reflected in a continuous
space. Firstly, based on ocean wind speed data gained from satellite
QuikSCAT, raw potential are identified. Those findings are then used along
with projections of current wind turbine technology development to calculate
the maximum amount of offshore wind energy that could be generated.
Secondly, to calculate practical potential, the migratory path of an endangered
bird and existing shipping lanes and submarine cables are excluded from the
calculated technical potential. 4km, 8km and 12km buffer to coast are
repsectively applied to avoid annoying visual impacts for coastal zones from
offshore wind farms. Thirdly, a GIS based cost model for bottom-mounted
offshore wind energy farms is established. Levelised production cost is
calculated and showed across wide regions, and sensitivity analysis is
conducted to reflect how various factors influence cost of energy. The results
of the study can serve as a foundation for future policy-making. More detailed
assessments at regional or local scale are needed for decisions on developing
offshore wind farms.
