Power supply situation after EVN's affirmation of 'sufficient power supply for the North'

Power supply in the North guaranteed after EVN announcement

Regarding the electricity supply situation after information from Vietnam Electricity Group (EVN), a representative of the Electricity Regulatory Authority said that from June 23, the Northern power system will basically meet the demand for electricity.

According to the Electricity Regulatory Authority, the reason is that the amount of water flowing into hydroelectric reservoirs has increased significantly in recent days. In addition, the incidents at thermal power plants have been resolved, the connection of renewable energy projects has also increased, the weather in the North has also cooled down in recent days, and the demand for electricity is no longer severe.

The report of the National Power System Dispatch Center (A0) shows that the total electricity output of the system on June 24 reached 773.4 million kWh, of which the Northern electricity output was 344 million kWh, with the largest capacity of 79.4 MW.

Regarding hydropower in the North, with the continued mobilization of Hoa Binh, Lai Chau, Thac Ba, Bac Ha, and Nam Chien 1 hydropower plants, the hydropower output exploited on June 24 reached 4,945 million kWh, an increase of 17.4 million kWh compared to June 23.

The amount of water flowing into hydroelectric reservoirs increased rapidly compared to yesterday: Lai Chau Lake: 782 m3/s; Son La Lake: 2,220 m3/s; Hoa Binh Lake: 769 m3/s; Thac Ba Lake: 341 m3/s; Tuyen Quang Lake: 901 m3/s; Ban Chat Lake: 805 m3/s. The current water levels of Son La, Lai Chau, Tuyen Quang, and Ban Chat lakes have all accumulated 10 - 20 m higher than the dead water level.

Mr. Tran Viet Hoa - Director of the Electricity Regulatory Authority - said that the North is currently in the early flood period. It is expected that in the coming time, the water flow to the lakes in the North will continue to increase and can ensure electricity supply with an average calculated load of about 421-425 million kWh/day.

However, due to the current low water level of hydroelectric reservoirs and the reduced available capacity of the generators, the maximum load response capacity of the Northern power system is about 344.0 MW depending on the time frame in June.

"In the extreme case of no flood or low flood flow to the lake, the Northern region can still use the remaining water in the lake combined with the natural water flow to the lakes to meet the load demand, however, the ability to store water will be difficult," said Mr. Hoa.

For the Central and Southern regions, ensure electricity supply and do not have to run on oil in the coming time. In some cases of unusually high load or incidents with many thermal power sources, it is possible to flexibly mobilize DO oil sources to meet the demand.

Regarding temperature, it is forecasted that the temperature in late June and early to mid-July will not be as extreme as in late May and early June, so the demand for household electricity is unlikely to skyrocket as in recent times.

The average daily load in the North is forecasted to be around 421.7 million kWh. If there is a reasonable operating regime and good implementation, synchronous solutions to ensure electricity supply, the Northern power system will basically meet the load demand.

Many solutions to ensure electricity supply in the future

To continue to ensure safe, stable and efficient electricity supply from now until the end of the dry season in 2023 and prepare for the dry season in 2024, Mr. Tran Viet Hoa informed:

"The Ministry of Industry and Trade continues to monitor and direct units to deploy a number of key solutions such as: Having a reasonable operating regime for hydroelectric and thermal power sources in the North; hydroelectric plants must closely follow weather developments to have appropriate operating regimes to ensure output and capacity."

At the same time, thermal power plants in the North need to ensure maximum availability and arrange enough coal fuel for electricity production. Thermal power plants must regularly monitor and closely follow the operation of the plant's equipment, absolutely not allowing subjective incidents to occur during the current period of power supply stress.

Units must speed up the progress of projects to increase transmission line capacity, strengthen on-duty work, inspect and review the transmission grid to quickly detect and handle equipment abnormalities, and minimize the possibility of incidents.

Continue to promote the synchronous and drastic implementation of solutions on electricity saving, concentrate resources, and speed up the progress of putting into operation types of power sources under construction, especially in the Northern region.

In order to cope with the risk of power shortages, on the afternoon of June 24, the Minister of Industry and Trade held a meeting with 10 provinces with liquefied natural gas (LNG) electricity, including: Quang Ninh, Thai Binh, Thanh Hoa, Nghe An, Quang Binh, Quang Tri, Ninh Thuan, Binh Thuan, Long An, and Bac Lieu.
At the meeting's conclusion announcement, the Minister of Industry and Trade requested the provincial Party Committee, People's Committees of provinces and cities and relevant agencies and units to speed up the progress of LNG power projects on schedule according to the approved planning.
For projects that already have investors, localities focus on urging progress and creating favorable conditions for investors to implement the project; promptly resolve or support the resolution of difficulties and problems (especially regarding land, infrastructure, environment, etc.) so as not to affect the project progress.
Actively and closely coordinate effectively with investors, the Ministry of Industry and Trade and relevant ministries and branches during the investment preparation and project implementation process to promptly resolve arising problems, ensuring progress and efficiency.
