Binh Thuan is considered as the "capital" of the country's wind power. There are about 20 wind power projects in the category of wind power project development up to 2020.
However, up to now, only two projects are operating in moderation because investors are not interested.
Experts and managers of electricity and energy consider that current wind power is inefficient for many reasons, so it does not attract investors.
Make up for long and long losses
At the end of 2010, Petrovietnam Renewable Energy Co., Ltd. (PVPower RE, a member of PetroVietnam Power Corporation) started construction of the Phu Quy wind power project with three wind turbine columns, the total 6MW capacity, investment capital is over 335 billion dong. By May 8-2012, this project officially operated with the first two tuocbin supplying electricity to Phu Quy. However, according to Mr. Pham Cuong - director of this enterprise, to break even every year, the corporation must cover a loss of about 10 billion dong.
“Wind power produces electricity to buy 6.8 cents (1 USD equals 100 cents), the State compensates 1 cent to 7.8 cents / kWh of electricity. Meanwhile, we calculate if using Chinese equipment, the purchase price must be over 9 cents to be profitable. Only the current project in Phu Quy costs 10.36 cents to recover the capital within 12 years ”- Mr. Pham Cuong said.
Mr. Pham Cuong compared wind power as a luxury product. Only developed countries accept high prices, Vietnam is still poor, so when the development of wind power without a separate mechanism, like other forms of energy, investors are not interested. “In Binh Thuan, there are about 20 wind power projects and only one unit can install 20 columns in Tuy Phong district, and we install three columns in Phu Quy. Most of the remaining projects are researching ”- Mr. Cuong said.
In Tuy Phong district, 20 wind power poles of Vietnam Renewable Energy Joint Stock Company (REVN) with a total capacity of 30MW have been connected to the national network. The above 20 columns are implemented in phase 1, completed at the end of 2009 with a total cost of nearly 1,000 billion VND. According to REVN's representative, with the current electricity purchase price, it takes a long time for investors to recover their capital.
Will not be as planned
Mr. Duong Tan Phong, head of the electricity and energy management department (Binh Thuan Department of Industry and Trade), said that according to the wind power development plan of Binh Thuan province for the period 2011-2020, the installed capacity reached 700MW. However, Mr. Phong assessed that without the adjustment of wind power policy, the above target is not feasible. "Try to achieve 500MW" - Mr. Phong said.
Mr. Phong analyzed that the current difficulty is that investors lack capital. "A wind power pole is invested up to millions of USD, but it is difficult for wind power to recover capital for a long time, so it is difficult to attract investors" - Mr. Phong added.
Meanwhile, Mr. Tran Ngoc Linh, director of Binh Thuan Power Company, analyzed technically, when the wind power operates, it also creates many problems. For example in Phu Quy island today, Mr. Linh said that the diesel-powered power grid is 3MW, but the source of the wind by design is 6MW, double the capacity of diesel. That is wrong about the technical solution. Solving this problem requires a very specific technical solution, for example, wind power must have a load storage system, but now it cannot be saved because equipment investment costs a lot of money. “Wind power is an additional source. Mechanism of operation, wind power itself must have a common support network ”- Mr. Linh explained.
Even though wind power is already running, people on Phu Quy island have not been able to use much more electricity, still only 16 hours / day like when there was no wind power. The reason is that wind power depends on wind power, so it only reaches 500-900kW / day when it is put into operation here. Wind power depends on diesel power, so when diesel power cannot run (only runs 16 hours / day), wind power cannot be regulated and regulated.
