VietNamNet Bridge – Water, “white coal”, is being exhausted, while the demand for electricity is growing alongside the national economy.
Therefore, building thermopower plants, which have big advantages (low installation costs, short construction times) will be top priority.
By the end of 2006, the total capacity of power sources had reached 12,270 MW, 57% of which (6,586 MW) came from thermopower plants.
Besides the expanded power plants belonging to the Electricity of Vietnam (EVN), including Pha Lai, Uong Bi, Ninh Binh, which help raise the capacity from 645 MW to 1,550 MW, Vietnam also has electricity sources from foreign invested plants like Cao Ngan (100MW), Na Duong (110 MW), Formosa (150 MW). Gas-run thermopower plants in the south, including Ba Ria (389 MW), Phu My (4,014 MW), and Ca Mau (480 MW), have also been put into operation.
It is estimated that the structure of power sources in Vietnam will see big changes after 2010, with the focus to be on thermopower development. A series of big thermopower plants will open, including ones in Quang Ninh (1,200MW), Hai Phong (1,200MW), Vung Ang (600 MW), O Mon (600 MW), Ca Mau (1,400MW), Nhon Trach (450 MW), Nghi Son (1,200 MW), Mong Duong (2,200MW) and others.
According to the power development strategy for 2006-2015, the total installation capacity of power sources will be 15,497 MW by 2011, and 27,261-27,811 MW by 2015.
How to develop thermopower plants effectively?
While affirming the importance of focusing on thermopower development, experts said that solutions should be found to tackle the disadvantages of this source of power.
The biggest disadvantages of thermopower plants are high regular expenses, the impact on the environment, and limited sources of materials (coal, oil and gas).
The current capacity of power generating units of coal-run thermopower plants is 300 MW at maximum. In the future, Vietnam will have to use modern technologies for coal-run plants, which ensure high productivity and acceptable investment capital. Moreover, the plants should have a high capacity of power generating units (300, 600, 1,000 MW). The gas-run power sources will only use mixed turbine engines with high capacity (150-250 MW).
