With the geographical advantages of highland and numerous waterfalls, hydropower resources of the area are large and are used effectively. Two hydroelectric power stations built in this region before are Da Nhim (160.00 kW) on Da Nhim River (source of Dong Nai River) and Dray H’inh (120.000 kW) on Serepok River. Moreover, the Yaly Hydropower Project has been in operation since 2000; other projects such as Bon Ron-Dai Ninh and Play Krong have been expected to build recently. Tay Nguyen (the central highland of Vietnam) does not abound in mineral resources but is abundant in bauxite reserves measuring at billions of tons.
