Abstract:As a new form of inter-regional energy transportation, the increasing inter-grid power transmissions will change the trajectories of regional energy consumptions, consequently, the emissions of air pollutants and greenhouse gases. Modeling and analyzing these impacts can support policy makers with regard to national and regional energy strategies, as well as emission control policies. This study applied a multi-region bottom-up optimization model for China’s electricity sector (BOMCES-ED) to simulate the impacts of inter-grid power transmissions on regional emissions and power sector developments, using the electricity generation technology mix of 2010 as the base year dataset. Results show that Northwestern Grid, which is expected to export the most electricity according to the strategic planning of ultra-high voltage power transmissions, will have to increase its coal consumption for power generation in an amount of 123.51Mt, causing the emissions of SO2, NOx, CO2 and Hg within the grid grow by 0.221Mt, 0.116Mt, 227.5Mt and 3.80t respectively in 2020. It is suggested to pay more attentions to ease the potential conflicts in terms of environmental loss and health risk resulted from inter-grid power transmissions.
