High-resolution gridded dataset of China’s offshore wind potential and costs under technical change

We provide three datasets for users. The first dataset contains 25 features of offshore wind in 5058 grid points at 10km resolution, under 3 technical change scenarios from 2020 to 2035, and stored in 3 NetCDF(.nc) files. The features include 1 time variable, 5 geographic features, 4 turbine characteristics, 2 technology selection variables (foundation and transmission), 9 technology costs by components, 1 resource variable, and 3 generation cost variables. The second dataset includes the spatial distribution maps of capacity factors, investment costs, and LCOE for typical scenario years (2020, 2025, 2030, and 2035 of medium scenario, and 2035 of high and low scenarios) which are stored in 18 GeoTIFF files at a 10km resolution. The third dataset offers hourly output curves for offshore wind power over 8760 hours at the 5058 grid points in 2020, stored in a NetCDF file for high spatio-temporal resolution power system modeling.
