tailieunhanh - Hydropower development and management

Vietnam‟s hydro-power resources are very plentiful and distributed widespread in national scope. Vietnam is one of 14 countries which are rich in hydro-electric resources in the world. Total hydro-power resources potential of more than 2200 mini, medium and large rivers (just mention rivers with more than 10 km in length) in national scope is assessed as follows: | ADB TA 4903-VIE WATER SECTOR REVIEW PROJECT STATUS AND ISSUES IN HYDROPOWER DEVELOPMENT Prepared for: Final Report Prepared by: HA TIEN LUY Energy & Hydropower Specialist 05 / March / 2008 A. Overview on hydro-power development status in national scope 1. Overview on Vietnam’s hydropower resources Vietnam‟s hydro-power resources are very plentiful and distributed widespread in national scope. Vietnam is one of 14 countries which are rich in hydro-electric resources in the world. Total hydro-power resources potential of more than 2200 mini, medium and large rivers (just mention rivers with more than 10 km in length) in national scope is assessed as follows: . Theorical potential: Vietnam‟s hydro-power resources is evaluated to be 300 billion KWh, with capacity of to MW. . Techno-economic potential: Vietnam hydro-power is about 82-100 billion KWh with capacity range from to MW as evaluated (about 30 to 33% of theorical potential) in which: - Large and medium hydro-power plants (the kind with capacity of the same or more than 30 MW/1 plant): as expected there are about 150 such plants, with total capacity around – MW (about 90-93 % of total hydro-power teachno-economic potential). See diagram and table - Small hydro-power stations (with capacity smaller than KW/1 station): it is expected to have total of capacity about -2000 MW (about 7-10% of total hydro-power resource economic-technological potential. 2. Operating and constructing hydro-power plants (to be put into operation in 2010) At present (to lately 2007), total machine capacity of Vietnam‟s operating hydro-power plants is MW, many year‟s average electricity is about 18 billion kwh. Therefore, more than 20% of total Vietnam‟s economic-technological potential was exploited. Regarding pump storage hydro-electricity at present, 10 feasible economic-technical projects with total machine capacity about MW was .
