Abstract: A solar chimney power plant (SCPP) is proposed to be built in Qinghai-Tibet Plateau where there is abundant solar radiation, high direct solar radiation low atmospheric temperature, large diurnal temperature range, and lots of salt lakes working as heat storage system, which can help to improve the power output of SCPP. The plant is expected to power local railway traffic lines and act as a solar power base to supply power for national development. The performance of the SCPP that will be built in Qinghai-Tibet Plateau is analyzed and power potential estimated by developing a simple mathematical model. It is found that SCPP if built in the plateau can produce twice more power than an SCPP built on the same latitude of other regions. The yearly power potential for SCPP in Qinghai-Tibet Plateau is estimated to be 86.8 million TJ. When 10-20% of the plateau land is used for the SCPP, the yearly power output may reach 8.7 million TJ to 17.4 million TJ, accounting for 10.7-21.3% of China's energy consumption in 2008 which stood at 81.6 million TJ. It is found that the SCPP in the plateau can support local and national development together with other renewable energy resources such as hydroelectric power and wind power.
