 The vision is for a total system capacity of about 3,400 MW, at a total investment of nearly US$12 billion, not including investment for connection to the national electricity system.Vietnam wind resource mostly lies along its coastline of more than 3,000 km, and in the hills and highlands of the northern and central regions.A World Bank ESMAP study (see the table below) estimated that over 39% of Vietnam's area had annual average wind speed over 6 m/s at a height of 65m, equivalent to a total capacity of 512 GW.
