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: 1.1.

Techno-economic potential: Vietnam hydro-power is about 82-100 billion KWh with capacity range from 18.600 to 20.000 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 18.000  18.640 MW (about 90-93 % of total hydro-power teachno-economic potential). See diagram 1.1 and table 1.1 - Small hydro-power stations (with capacity smaller than 30.000 KW/1 station): it is expected to have total of capacity about 1.600 -2000 MW (about 7-10% of total hydro-power resource economic-technological potential. 2.

Role of hydro-electric development in Vietnam’s energy sector, economic significance and contribution of hydro-electricity toward Vietnam’s GDP. 3.1. situation of carring out Electric power development in period V – period 2001- 2010 and perspective up to 2020 ( is abbreviated to MPEPD - 5 ; MPEPD-V ; or in Vietnamese is TSD - 5 ; TSD - V ). 3.1.1. Compare real energy demands and one according to the forecast TSD V is carried out in period 1998-1999, therefore, results forcasted (energy and capacity) may be compared to real data in period 2000 - 2005. real values is higher than all methods of forecast (high, low, medium) of TSD V. High case has smallest disparity between forecasted value and real data . The reason is that TSD V was established at the time when economic financial crisis happened in the area, therefore forecast of economic growth speed (according to national wide and economic sectors in common), invested capital estimated as well as reconstruction of industrial zones, export processing zones, large factories all are at rather modest starting point. So, commodity energy and maximum additional charge capacity are smaller than ones in reality during last years. Comparision of energy demand forecasted results of TSD 5 with the fact of encreasing energy demand (2000-2005) is shown in table 2.1. 7 Table 2.1.

Namely, high energy forecast method has average absolute error of 3041.7 GWh,  With regards to max capacity demand (Pmax), high method also has error in a permitted limit. Namely, high method has mean absolute error of 898.8 MW, with Std.Dev of 354.6 MW. Similarly, high method has mean relative error of 15.38% with Std.Dev of 3.99% After assessing the high rise of additional charge in years of 1999 - 2001, economic and envestment growth efficency due to timely and flexible managing methods of goverment, early 2002, electric sector actively revised some contents of TSD V such as: 2005 electricity demand was forecasted to be 53,4 TWh, 15% higher than the one of 46,5 TWh; and one of 2010 is 96,1 Wh, 23% higher than one of 78,5 TWh (high method of TSD V); push up some resource projects and transfered and loaded networks ext. Therefore, during 2001 to 2005 electricity sector basically met highly increasing demands of electricity, serving economic and social development. Table 2.4 and picture 2.1 show us sumarized, assessed and forecasted numbers of electricity demand in TSD IV, V, and revised TSD V compared to reality of 1995- 2005 period. One of big impacts which affected electricity demand recently is Asian Sou  financial monetary crisis in 1997. it caused a decline in foreign investment and internal industry during those years.
