EVN to cut 8 billion kWh of coal-fired power output

HCMC – State-owned corporation Vietnam Electricity (EVN) expects to cut 8 billion kWh of coal-fired power output this year to increase the portion of solar and wind power, Nguyen Duc Ninh, director of the National Load Dispatch Center, said at a meeting on May 4.

EVN has planned to mobilize some 32 billion kWh of solar and wind power this year, twice as much as 2020. As of late April, the total capacity of solar farms was 9,200 MW, while that of rooftop solar power and wind power was some 9,600 MW and 612 MW, respectively. Some new wind farms with a total capacity of 4,500-5,400 MW are expected to be put into operation in the rest of this year.

According to EVN, the large production of renewable energy has also put pressure on the electricity system and transmission lines.

Overloads have been reported in Ninh Thuan, Binh Thuan and some central provinces, especially midday from 10 a.m. to 2 p.m. when the electricity demand is low and solar power capacity reaches its peak.

Nguyen Duc Cuong, member of the Board of Directors of EVN, said although the output of renewable energy has soared, Vietnam still needs to maintain other sources such as liquefied natural gas-fired, coal-fired and hydro power.

“With advanced technology, coal-fired power plants have been able to solve many problems, including environmental pollution,” he stressed.

According to the National Load Dispatch Center, Vietnam’s capacity of solar and wind power will reach some 20,000 MW this year, accounting for over 30% of the total power capacity. However, renewable energy output contributes only 12% of the total and is expected to rise to 17% in the next five years.

Therefore, the country needs to maintain the portion of traditional energy (liquefied natural gas-fired, coal-fired and hydro power) at 40-80% to ensure power security.

EVN has planned to cut 1.3 billion kWh of renewable energy in 2021. The corporation said in the coming time, it will cut renewable energy capacity by 15-20%. Particularly, solar power and wind power output will be cut by 13.3% and 4.8%, respectively.

The Ministry of Industry and Trade said the development of renewable energy, especially solar power, has seen positive results, attracting large investment and contributing to effectively exploiting the potential renewable energy resources in the country.

However, the boom of high-capacity renewable energy plants, mainly in the central and southern regions, has overloaded inter-regional transmission lines and caused an oversupply.
