Quantifying Cross-provincial Power Transmission Barriers in China, Based on A Computable General Equilibrium Approach

Type: conference-paper
Abstract: Long-distance high-voltage power transmission has been developing at an unprecedented rate in China, connecting the power-rich northwest and southwest with Central and Southeast China, where most of China’s power demand locates. Albeit the fast increase of long-distance power transmission capacity, intangible transmission barriers start to appear, which restrict power transmission and result in renewable power curtailment. The barriers stem from the immaturity of power market. Therefore, considerations from government on economic and social viewpoints gain more weight. In this paper, economic and environmental impacts of power transmission on a power importing province are quantitatively analyzed based on a computable general equilibrium (CGE) model. The power transmission from Sichuan, a typical hydropower exporting province, to Jiangsu, a typical power importing province and one of China’s most developed regions with large power demand, is analyzed as a case study. Results show that both economy and greenhouse gas emissions in the power importing province tend to decrease. It indicates that traditional government performance appraisal system, mainly values economic growth, would take partial responsibility for the barriers and the curtailment. Taking environmental assessment index into consideration would lower the barriers. Establishing a mature power market is the fundamental way to eliminate the barriers.
