With GDP annual growth over 5% and in the process of expanding global cooperation and trade so Vietnamese demand for energy is becoming urgent and the supply always overworks to satisfy growing demand day by day. The growth of Vietnamese electricity consumption is always over 9% and after 10 years from 2005 until now electricity consumption increased from 51.4bn KWh to nearly 140bn KWh. With the average growth rate in the recent years about 9% - 10% we can forecast the demand will reach 220bn KWh.
