According to Vo Quang Lam, deputy CEO of EVN, the total designed capacity of all electricity generation units is 48,000 MW, but the usable capacity is 39,000 MW only.

With the demand increasing by 10 percent per annum, Vietnam will need 4,000 MW more next year, or 43,000 MW in total.

Vietnam is witnessing a solar power boom. But the electricity output from solar power plants is small compared with demand.

With the demand increasing by 10 percent per annum, Vietnam will need 4,000 MW more next year, or 43,000 MW in total.

The total electricity merchandise output in 2019 is 212 billion kwh, which means that Vietnam needs 750 million kwh a day.

Meanwhile, the solar electricity output could be up to 27 million kwn at maximum. As such, Vietnam needs 720-730 million kwh of electricity from other sources, including coal-fired, gas-fired and hydraulic power plants.

Lam said the low capability of the transmission line for solar power is a problem. Many solar power plants have been set up in the provinces with high solar radiation levels, but the electricity output from the plants cannot be used up because of the transmission system overloading.

Meanwhile, according to EVN, many electricity generation projects are running slowly and cannot become operational on schedule, worsening electricity shortage.

MOIT warned that because of the tardiness, Vietnam will lack electricity in 2021-2025, even if EVN mobilizes all electricity generation sources, including oil-fired plants.

The ministry predicts that Vietnam will lack 6.6 billion kwh in 2021, while the figure will rise to 11.8 billion kwh in 2022 and to 15 billion kwh by 2023, or 5 percent of demand. The electricity shortage will be eased in 2024-2025, when Vietnam gets power from B-block and Ca Voi Xanh gas-fired hydropower plants.

Lam said that the growth rate in electricity demand would be 10 percent per annum from now until 2025. As for traditional electricity types, Vietnam now can exploit coal-fired and gas-fired power only, while hydraulic power potential has been exhausted.

Meanwhile, he expressed worry about the coal supply for coal-fired power plants. VInacomin and Dong Bac Corporation, the two biggest miners, are meeting difficulties in exploiting coal. While coal exploitation output has not increased, the coal price has increased. Therefore, EVN has to think of importing coal and gas.

At the Vietnam Energy Forum held recently, Nguyen Quan, former Minister of Science and Technology, proposed developing nuclear power to satisfy domestic demand.

Vietnam once thought of developing nuclear power but decided to cancel the project in 2016.

Warning of electricity shortage, Vietnam seeks energy savings

The demand for electricity merchandise will be high in the upcoming years: 235 billion kwh, 352 billion kwh and 506 billion kwh by 2020, 2025 and 2030, respectively.

Big cities in Vietnam burn waste to generate electricity

Hanoi, HCMC and other big cities are using waste-to-electricity (WTE) technology to treat domestic waste and produce much-needed power.v
