Northeast Asia is one of world's major economic and energy consumption centers. Countries in this region are undergoing rapid economic and social development

and energy security and greenhouse gas emission reduction have become prominent issues. In this region

clean energy resources including hydro

wind

and solar are concentrated in Russia

Mongolia

and Northeast China

whilst electricity load centers are in East China

Korea and Japan. Currently

an energy and electricity model has been developed to project electricity demand through 2030 for each country. Based on the idea of a Global Energy Interconnection

this article proposes to establish a Northeast Asia Grid Interconnection (NEAG)

connecting Mongolia

China

Korea

Japan

and Russia with large volumes of transmission lines

in an effort to facilitate optimized resource allocation. The NEAG would be accomplished step by step along with identification of key interconnectors. China is set to play an important role in establishing the NEAG by providing a strong sending grid and necessary technological equipment. Tremendous economic

environmental

and social benefits are expected to be generated by the NEAG.
