It is reported that Nguyen Dening, director of the National Power Dispatching Center of Vietnam, recently stated that in 2021, Vietnam plans to cut 500 million kWh of photovoltaic power generation. In 2020, the installed capacity of renewable energy projects such as photovoltaic power stations, especially rooftop solar power stations, will show "explosive" growth, resulting in overcapacity during the peak hours of photovoltaic power generation in Vietnam at noon and overloading of the 500kV power transmission channel in the north and south.

In the whole year of 2020, the newly installed rooftop photovoltaic capacity in Vietnam will exceed 9 GW. The cumulative installed capacity of rooftop photovoltaics increased from 378 MW in 2019 to 9.583 GW, an increase of 2435 percent. Ruan Dening pointed out that in June 2020, the peak output power of rooftop solar power has reached 6000 MWp, and it has climbed to 10000 MWp by the end of the year. In Ningshun, Binh Thuan and some central provinces, the scale of photovoltaic power curtailment has reached 365 million kWh.

Vietnam needs to reformulate its energy policy

The Vietnam Power Group has pointed out in a report released not long ago that in Vietnam, photovoltaic power generation has accounted for a quarter of the entire power system, and the explosive growth of photovoltaic installations has affected the stability of the power distribution system in Vietnam. Sex.

As early as the 2019 Vietnam Photovoltaic Exhibition, a salesperson from a Chinese inverter company said: "The installed photovoltaic capacity is growing too fast, but the foundation of the Vietnamese power grid is too weak. Although the projects seem to be connected to the grid, they will appear later. The possibility of'power curtailment' is very high."

Ruan Dening pointed out that the recent development of rooftop solar energy has led to an embarrassing situation. It is necessary to formulate clear industry standards and related policy rules, make overall considerations, and limit disorderly development. Ruan Dening revealed that currently, the Vietnamese government has suggested that some small hydropower projects adjust their power generation time and suspend power generation during the peak period of sunshine from 11 to 13 o'clock every day to make more room for photovoltaic projects.

In this regard, the US Institute of Energy Economics and Financial Analysis also pointed out: “Vietnam's energy authorities need to fully consider the rapid and bold development momentum of the renewable energy industry and reformulate energy policies.”

IEEFA further stated that the surge in installed photovoltaic capacity on rooftops in Vietnam shows that local private investors are enthusiastic about investing in renewable energy, and they also have strong risk resistance capabilities. "According to the statistics of the Vietnam Banking Association, as of June 2020, domestic banks in Vietnam have provided loans of up to 360 million U.S. dollars to renewable energy projects, and only one third of the payments were made in the first half of 2020. "

IEEFA emphasized that photovoltaic power plants invested and built by private capital are booming, and their power generation has reached more than 3.5 times of the Vietnamese government’s "2016-2020 Renewable Energy Capacity Plan", and it is expected that there will be large-scale wind power projects by the end of 2021. Completion and delivery. "Compared with traditional energy, the developers of renewable energy projects have more decisive decision-making capabilities and project delivery capabilities. In 2020, after several rounds of planning and demonstration, Vietnam has only added 1.2 GW of coal power installed capacity across the country. This speed is completely incomparable with renewable energy sources such as photovoltaics. The official renewable energy forecasts are often very conservative and are far behind the actual development of the electricity market. This poses a huge challenge to the Vietnamese government’s electricity planning." Sang Xiaomei
