The construction is part of China's multiyear plan to build a “solar great wall” designed to generate enough energy to power Beijing. The project, expected to be finished in 2030, will be 400 kilometers (250 miles) long, 5 kilometers (3 miles) wide, and achieve a maximum generating capacity of 100 gigawatts.
Li Kai, an energy official in Dalad Banner, where part of the great solar wall is located, told the state-sponsored media outlet China Daily: "All of the projects are invested in by state-owned companies, some of which are centrally administered ones, and so local governments don't have to make any investment at all.
