Features of Geography and Meteo-hydrology

Gross area of Vietnam is S = 331.000km 2 , in which 4/5 of this

is mountainous areas and highlands

Vietnam is S-shaped, length of 1630km prolonging from the

North to South Largest width of the North and South is 600km

and 370km, respectively, while it is narrowest in the Central part

of Vietnam, Quang Binh province (Dong Hoi provincial town),

as of 50km

Vietnam is located in the tropical monsoon area, hot and humid,

with large amount of rainfall Average Annual Rainfall is some

of 2,000 mm, in which highest and lowest one is

4,000-5,000mm and 1,000mm, respectively In general, rainy season

lasts from 3 - 5 months but unevenly distributed in term of

spacial aspect.

River network of Vietnam is densely presented in which 2,400

rivers are longer than 10km Almost all rivers in Vietnam flow

into the East Sea.

Gross Run-off Volume is 870 bil m3/year, presented as Annual

Average Discharge as of 37,500 m3/s

www.vncold.vn

- Theoretical Potential: about 300 bil kWh (only

accounting for rivers with length of over 10km)

- Technical Potential: about 123 bil kWh, referred

to as Installed Capacity of 31,000 MW

- Technical-Economic Potential is identified as

some of 75-80 bil kWh, equivalent to capacity as

18,000-20,000MW

By the year 2006, Total Capacity of Existing

Hydropower Plants in Vietnam is 4460 MW

which is considered as 18 bil kWh of Average

Annual Energy Production It has been, therefore,

over 20% of technical-economic potential

exploited

www.vncold.vn

Power Energy Potential of Medium and Small

Scaled Hydropower Projects lower 30MW.

Total Technical-Economic Potential of Hydropower

Projects ≤ 30MW, some of 300 projects, is in the

range of 2,500-3,000 MW, referred to as 10 bil kWh

of Average Annual Energy Production

Power Energy Potential of Pumped Storage Power

Projects: 10 of Pumped Storage Power Projects, total

capacity of 10,000MW, has been identified viable in

term of Technical-Economic aspect (i.e in Sonla

province: 7 projects, Hoa Bình: 1, Ninh Thuan: 1 and

in Binh Thuan province: 1 project) Pre-feasibility

Report of 2 projects, 1 in Sonla and the other in Ninh

Thuan, has been prepared

www.vncold.vn

b- EVN has been conducting construction of projects > 30MW , which total capacity is 6,500MW,

to commission in 2010

At the present, 19 projects invested by EVN are under construction.

In which Sonla hydropower plant, 2,400 MW, is the biggest one in the South East Asian The first and

second units are planned to commission by late 2010 and project completion in late 2012

d Pumped Storage Power Plants, EVN: These planned projects, total capacity of 4,800MW, will be commissioned in the period 2018-2022.

e- Hydropower Plants, N >30MW: these will be invested by local units in the form of BOT and IPP, and planned commissioning as follows:

- Period 2006 – 2010 : 920MW

- Period 2011 – 2015 : 3100MW

- Period 2016 – 2020 : 1000MW

g- Small-scaled Hydropower Plants:

1,000 MW from small-scaled hydropower projects (i.e projects <30MW) will

be generated in the period 2006- 2010, about 500 MW in 2011-2015 and 1,000 MW in 2016-2020

www.vncold.vn

- Interconnecting with Lao:

Immediate projection is that hydropower plants of Lao

such as Nam Mo (100 MW) will be interconnected with

Vietnam via transmission line 220 KV running through A

Vuong HPP to Da Nang city

In Power Development Plan No 6, an amount of

1,000MW will be imported from Lao up to the year 2010

and an increase of 2,000MW beyond 2010 via 2

directions as follows:

+ The first direction: from Central of Lao( Nam Thueon

2, 688MW) to Ha Tinh province

+ The second direction: from the South of Lao( Ban Sok),

Sekaman 1, Se Kong 4, 5 and Nam Kong, total capacity

of up to 1,600MW to Pleiku (Gia Lai)

Due to the delay of proposed development plans of

hydropower projects in Lao, construction of planned

transmission line 500kV will be backward 2010

www.vncold.vn

Interconnecting with Cambodia

+ In the period 2008 – 2010: Vietnam will provide

Cambodia with 150-200MW via transmission line

220KV from Cuu Long River Delta (i.e proposed

from transformer station 220KV, Thot Not)

running through Chau Doc and Ta Keo to Phnom Penh

+ In the period 2010 – 2015: proposed

construction of hydropower projects as Lower Se

San 2 (430MW) and Se San 1 & Se San 5

(100MW) will be implemented and transmitted to

the North of Ho Chi Minh city and transformer

station Pleiku, respectively

www.vncold.vn

Interconnecting with Van Nam province of

China

+ It is planned that 250 -300 MW will be imported via transmission line 220KV Lao Cai – Yen Bai -Viet Tri in 2006

+ In the middle of 2007, 200MW will be imported

to Ha Giang - Thai Nguyen

+ Possibility of electricity importation 1,500MW in the period of 2006-2018 via transmission line 500KV is considering to connect transformer station 500/220KV Hong He (Hong Ha – Van Nam province) with the one of Soc Son

Average Investment Capital for itself EVN in the period of 2006- 2015 is USD 4 billion per year, orientation of capital mobilization methods are as follows:

- Privatization of Power Plants and Power Companies

- Domestic Credit and Bond issue

- International Credit and Diversification of Different Financing Sources
