Experts: Vietnam has large wind power potential

Hanoi (VNA) – Vietnam has huge potential in terms of geography and wind
power resources to generate electricity, experts have said.

The western part of the East Sea bordering southern Vietnam is one
of two areas with an average wind speed at sea of 10-11km per hour, according
to research from the Vietnam Institute of Seas and Islands under the
Ministry of Natural Resources and Environment (MONRE).

The water from the central province of Binh Thuan to the southernmost
province of Ca Mau – especially the area 300km from the shore – has wind speed
of 7-11km per hour on average, making it one of the areas with the highest
potential of generating electricity from wind energy in the world, according to
the research.

At a height of 80 metres from the surface of the East Sea, the
extended area in the northeast-southwest direction from the Taiwan Strait to
waters off Vietnam’s southeastern region has power capacity of 600-800W per
square metre per year.

Waters off the South Central Coast have power density of 400-700W
per square metre, and those off the Gulf of Tonkin have power density of
400-500W per square metre.

Forecasts from wind power experts show that wind power from the
country’s sea will continue to increase, alongside wind power from mainland,
reaching 100GW and higher by 2030.

Large areas of sea have potential for developing offshore wind
power constructions, according to Dr Du Van Toan from the Vietnam
Institute of Seas and Islands. He cited the 142,000sq.km sea area in the
southern region and the 44,000sq.km sea area from the central province of Binh
Thuan to the southernmost province of Ca Mau.

Statistics from 1,500 wind farms in the country (some are in the
process of developing further) in the last decade show that the average wind
speed of 7-12.5m per second at 100m above sea level generates the most wind
power, which is highly effective for consumption and trade.  

Projects exploiting wind power in Vietnam are developing well,
especially two major projects wind farms in the southern Bac Lieu province and
southernmost Ca Mau province, which are expected to generate 1,000 MW of wind
power by 2020 and 2025, respectively.  

The wind farms and wind power plants have been contributing to the
provinces’ budgets by selling electricity to the Electricity of Vietnam Group (EVN).

For example, the 100 MW Bac Lieu
wind power plant in the southern province of Bac Lieu has been
contributing some 76 billion VND (3.3 million USD) per year to the local budget
since 2010. It is expected to increase its capacity to 400 MW and contribute
some 300 billion VND (13.2 million USD) per year to the local budget soon.

On January 16 last year, construction of the 100MW Khai Long wind
power plant began in the southernmost province of Ca Mau. It is expected to generate
300 MW of wind power and some 200 billion VND (8.8 million USD) per year by
2018.

This high potential should Vietnam to establish a wind energy
development strategy which includes developing wind power construction on the
sea, said Dr Du Van Toan.

“We will be able to further develop the economy and prevent
landslides and land erosion if we know how to utilise wind power resources
together with other sources of power such as solar power, wave
power, ocean thermal energy conversion, as well as biomass energy,
aquaculture and aquatic conservation,” he said.

“On the other hand, offshore wind power constructions not only
create new tourism attractions but also help strengthen the protection of
national sovereignty on the sea,” he said.-VNA
