No more wind and solar power sources to be added this year

HÀ NỘI — The Ministry of Industry and Trade will not add any more wind and solar power into this year's plan, due to a lack of input facilities to transfer them to the national grid.

At the  二0 二 一 review meeting of the National Load Dispatch Center on January  一0, its deputy director Nguyễn Quốc Trung said the total electricity produced and imported including rooftop solar power output was expected to reach  二 七 五. 五 billion kWh this year, up  七. 九 per cent compared to  二0 二 一.

Trung said that total hydropower output was expected to be  八 二. 五 billion kWh,  三. 八 billion kWh higher than in  二0 二 一.

Traditional power sources expected to come into operation in  二0 二 二 were  三, 四0 七 MW, including large thermal power plants with a capacity of  六00 MW each plant, such as the Nghi Sơn  二 and Sông Hậu  一, with no more wind power, farm solar power and rooftop solar power to the grid this year.

Trung also said the southeast gas source would reach  一 三. 五 -  一 四. 五 million cubic metres per day, while the southwest gas sources would reach from  三. 九 -  四. 五 million cubic metres in the year.

Buying electricity from China with an output of about  三 八0 million kWh in May and June was also expected.

For the north of Việt Nam, Trung said the peak load was expected to grow by  九. 五 –  一 三 per cent, or increase by  二, 四 九 七 -  二, 八 七0 MW in the year.

Though the north will have many potential risks of shortages during peak capacity, especially during the peak hot months from May to July, the National Load Dispatch Center has proposed asked to adjust the repair schedule, changing the wiring in Nghi Sơn when necessary so that the Nghi Sơn  二 plant could supply the region when necessary, together with calculating the purchase of Chinese electricity under the direction of Vietnam Electricity (EVN).

“Currently, low cost gas fields are decreasing while high cost gas fields were put into operation with the policy that BOT gas-fired power plants continue to be used, leading to the higher cost of new gas fields, affecting the electricity cost of the whole system,” Trung said.

Even after energising all approved new projects to ensure power supply to important load centers such as Hà Nội and HCM City as well as to release renewable energy (RE), most of the  五00kV transformers were at full load.

“The using of RE sources in  二0 二 二 continues to face many difficulties, because the power grid has suffered with the amount of RE sources that have been put into operation in recent years,” Trung said.

The challenges were reported in the provinces of Bình Định, Khánh Hoà, Phú Yên, Đắk Lắk, Đắk Nông, Kon Tum, Gia Lai, Ninh Thuận, Bình Thuận, Cà Mau and Bạc Liêu.

In addition, with the increasing rate of RE sources put into operation, the problem of stabilising the power system in real time was still a big challenge, he added.

Last year, the total new power source put into operation was  七, 四 三 三MW, bringing the total installed capacity of the national power system to  七 八, 六 八 二MW including  七 五 wind power plants with a total capacity of about  三, 六00 MW.

By the end of  二0 二 一, the total number of national dispatching plants was  三 三 七, an increase of  七 三 plants compared to  二0 二0.

Currently, there are  一0 四 plants directly participating in the power market with a total installed capacity of  二 七, 九 九0MW, accounting for  三 六. 八 per cent of the total installed capacity of power plants. During the year, four new factories entered the market with a total capacity of  三 七 二MW.

In addition, the national dispatcher energised, tested and accepted many important transmission lines and transformers projects on the  五00kV power grid such as energizing eight new transformers with a total capacity of  四, 三 八 七 MVA, increasing the capacity of five transformers with a total capacity of  三, 九00 MW, and  一 四 newly energised  五00kV lines with a total length of  二,0 二 二km. 

At the same time, the industry has built  二0 三 new  二 二0kV -  一 一0kV transformers with a total capacity of  一 三,0 一 六 MVA, and  二 三 六 new sections of  二 二0kV -  一 一0kV transmission lines with a total length of  三, 四 五0km. — VNS
