Abstract

Developing renewable energy is crucial for achieving China's carbon neutrality target by 2060. Xizang has a large renewable energy potential, especially hydropower potential, and it could become an important source of clean energy. Meanwhile, climate change has been affecting and will significantly alter hydropower resources in Xizang. This study estimates the development of Xizang's power system and its role in the national power supply under China's carbon neutrality target. In particular, it considers the changes in theoretically available hydropower potential from glacial retreat and transmission-supporting policies. The results show that considering the hydropower potential changes from glacier retreat under climate change, an additional 5.7–6.8 GW of hydropower capacity could be developed in Xizang by 2060, concentrated in Linzhi and Naqu areas. This additional hydropower capacity could increase to 15.9–17.7 GW if transmission subsidies are provided. Under such a scenario, Xizang could export renewable electricity to other provinces for up to about 3 % of the national electricity demand by 2060. The results indicate the importance of considering the impacts of climate change in power system planning and implementing transmission-supporting policies, which could facilitate Xizang to become a renewable energy base for China.
