Organisational Structure of EVN

Electricity of Vietnam (EVN) is a state-owned utility established in 1995. It is engaged in generation, transmission and distribution of electricity in the whole country.

The EVN oversees the various entities or business units engaged in generation, transmission, distribution, and associated service functions along commercial lines. These business units are grouped as either dependent (generation and transmission entities attached to EVN accounts) or independent accounting units (distribution and supply entities detached from EVN accounts). In spite of strong government regulation of power tariffs, the EVN is capable of raising profits out of its operations and to source external funds subject to approval of appropriate government agencies for infrastructure development, network expansion, and human resource management.

In the power industry, there are National Load Dispatch Center, fourteen main power plants, four transmission companies, and the Institute of Energy operating as dependent accounting units under EVN. The independent accounting units are seven distribution power companies, four design and engineering companies, two power equipment manufacturing companies, and one electric telecommunication company.

Generation Facilities

In 2001, the total installed capacity of Vietnam reached 8,478 MW, of which 7,878 MW are operated and owned by EVN and the remainder of 600 MW are owned by the IPPs. Hydropower accounted for 48.6 percent, coal and oil 13.4 percent, gas turbine and diesel 30.8 percent, and the remainder of 7.2 percent came from IPPs with mixed use of fuels.

The total amount of electricity generated was 30,600 GWh, of which hydropower generation accounted for 59.5 percent, coal-fired 10.5 percent, oil-fired 3.6 percent, gas turbine (gas) 14.4 percent, and 7 percent turbine+Diesel (DO), and 4.9 percent from IPPs. (Shown in figure of below). The growth rate power generated over the year 2000 is 14,3%.

The total new capacity added to the power system in 2001 was 2225 MW. They were: hydropower Yaly unit 3,4 (360 MW), hydropower Ham Thuan-Da Mi (475 MW), GTCC Phu My 1(1090 MW), and Coal-Fired Pha Lai (300 MW).

Averagely, the growth rate of power energy produced over the period from 1995 to 2001 is about 13,1%, reaching 30.6TWh in the year 2001: The peak load of the system has been increased from 2,774 MW in year 1995 to 5,600 MW in year 2001, the annual Load Factor (LF) of VN is about 62%.
Record of peak power demand and energy generation in period 1995-2001 shown in figure below.

In 2001, EVN's turnover was about 18.800 billions VDN (about 1.25 Billions USD), with sales volume of 25.8 TWh. Compared to previous year, sales volume increased by 15% and number of customers by 13% (amounted to 3.8 million customers). Customer category and market segmentation construed of: industry (40.4%), residential (49.1%), Commercials and services (4.9%) and others (5.6%).

Since 1995, the two graphs below shown the situation of the load demand over the past seven years.

The average energy sales growth rate in period 1995 - 2001 was 15%.

Transmission and Distribution Facilities

Transmission voltages in Vietnam are 500 kV, 220 kV 110 kV. The total length and substation capacity at various voltage levels are the following:

Voltage Level,kV	Length of line, km	Transformer's Capacity,MVA
500	1529	2580
220	3706	7170
110, 66	7900	9000
Medium voltage	79800	3016

The medium voltage network is planned for integration with 35 kV for the mountainous and rural areas and 22 kV for the urban areas. In the next five years, the 6 kV network will be upgraded to 22 kV. The 10 kV and 15 kV transmission lines will be step-by-step replaced by 22 kV or 35 kV in the future

Rural electrification

As of December 2001, 97.6 percent of the total districts have been connected to the national grid, the remaining districts (2.4 percent) are provided with off-grid local power supply. About 87 percent of the communes, and 77.4 percent of rural households have been provided with grid electricity.

Presently, the ceiling price of 700 VND/kWh (4.67 US cents/kWh) mandated by the Government to rural households is strictly being applied to 81.4 percent of the communes.

EVN has made a great effort to support provinces in providing rural households with affordable electricity supply.
