Abstract: Abstract Chinese government enacted the Renewable Energy Law and started the full-scale introduction of renewable energy power generation in 2006. The Chinese government has put particular effort into the spread of wind power generation, and the installed capacity of wind power generation in China surpassed that of the United States to become the world’s largest in 2011. However, most of China’s wind farms were built in the northwest where land prices are cheaper and wind resources are abundant. These areas are far from the eastern coastal areas, which have a high demand for electric power, and a strong power transmission network is required to utilize the electric power in the eastern coastal areas. But the wind power plant output was curtailed since the power transmission network was not sufficiently developed. It is too costly to transmit the wind power generated in the northwest to the eastern coastal area using the existing 220 kV transmission lines. Therefore, this study examined the economic efficiency of power transmission at a high voltage of 750 kV. As a result, it was found that the point with the lowest cost became far from the metropolitan area (expanded from about 120 km to about 500 km), and it was found that the economic efficiency of power transmission from the northwest to the capital district (Beijing and Tianjin area) was secured.
