- Theoretical Potential: about 300 bil. kWh (only

accounting for rivers with length of over 10km).

- Technical Potential: about 123 bil. kWh, referredto 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.

Power Energy Potential of Medium and Small

Scaled Hydropower Projects lower 30MW.

Total Technical-Economic Potential of HydropowerProjects 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 PowerProjects: 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 Bnh: 1, Ninh Thuan: 1 andin Binh Thuan province: 1 project). Pre-feasibility

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

Thuan, has been prepared.

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 underconstruction.

In which Sonla hydropower plant,

2,400 MW, is the biggest one in the

South East Asian. The first andsecond 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

- 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 2directions 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

8/8/2019 LVDaiEW1

22/24

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

8/8/2019 LVDaiEW1

23/24

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 importedto 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.
