Abstract: Clean energy resources, especially hydropower resources are very rich in Tibet. However, due to the low level of power source development and the mismatch between the power output characteristics and the grid load characteristics, the Tibet Power Grid have long been “surplus in flood season and shortage in dry season” in power supply and demand characteristics since the “12th Five-Year Plan” period. As the development of clean energy resources continues to increase, the overall production scale of Tibet's power supply during the “14th Five-Year Plan” period will far exceed its actual electricity demand, but most of the newly added power sources are far away from the grid load center. It is therefore the primary objective of the Tibet's “14th Five-Year Power Development Plan” to meet the electricity demand, promote the coordinated development of power supply and grid, and lay the foundation for the construction of the national clean energy base. According to Tibet's power grid structure, power sources distribution, and power supply and demand situation, and combined with the characteristics of energy resources, the power development focus of Tibet's “14th Five-Year Plan” are clarified in this paper through study and comparison of the power supply measures in the “14th Five-Year Plan” period and the years afterward.
