The project under consideration aims to construct a 10MW-scale solar power generation system in Altai City, Gobi-Altai aimag, Mongolia, and sell the generated energy to Altai-Uliastai Energy System. Currently, of all electricity supplied, approximately half is covered by import from coal-fired power plants of neighboring Central Energy System and Western Energy System, 40% by hydroelectric plant, and the rest by small-scale diesel power plants. The implementation of the project reduces GHG emissions by replacing electricity by coal-fired and diesel power plants which have high emission factors, with a solar power generation system, thus resolving the grid’s electricity shortage problem due to increasing power demand.
