Considering the additional electric energy generated after the full operation of the underground hydropower station, the electric energy accommodation of the Three Gorges Project (TGP) is reviewed. It is focused on the additional electricity accommodation, based on the research at the early stage. The electric energy accommodation solutions are recommended as that, based on the cost-benefit analysis of the power distribution area, the additional electric energy of the Three Gorges should be given priority to meet the needs at the supply end of Hubei and Chongqing. The results of this research has a reference value on the implementation of the Three Gorges electric power accommodation, after the further optimization of the transmission curves in both wet and dry seasons.
