Power consumption in third quarter of the whole country and the South sharply decreased compared to the second quarter and the same period of 2020

According to data from the National Load Dispatch Center, due to the impact of the COVID-19 pandemic in many provinces/cities, the power consumption in the whole country and the South in the third quarter sharply decreased compared to the second quarter and the same period in the third quarter of 2020.

If comparing the average daily power consumption output on a national scale, the power consumption in Q3 of this year decreased by 10.53% compared to Q2 of 2021 and by 4.14% compared to the same period in Q3 of 2020. At the same time, if comparing the average daily power consumption output of the South alone, the power consumption in Q3 of this year decreased by 23.41% compared to Q2 of 2021 and decreased by 13.59% compared to Q3 of 2020 (detailed data as in the table below).

To enhance public and transparent information on the operation of the national power system, from the end of September 2021, the National Load Dispatch Center (A0) publishes daily data at the end of the afternoon about the expected mobilized power capacity of the next day according to each type of power source in 2 typical time frames: (i) Noon (the solar radiation is the largest but the power consumption is low) and (ii) Afternoon-evening (power consumption is highest but solar radiation is very low). These data are published and posted on the website of A0 (https://www.nldc.evn.vn).

Based on the generation/load information published by A0, the power source investors in the system will see the overall power consumption situation of the country, the level of mobilization demand to corresponding power sources. The dispatching and mobilization of power sources, in addition to the requirement of closely following the power consumption demand of the whole country and each region, must also meet technical requirements to ensure the safe and stable operation of the power system such as: operation capacity of power transmission lines, ensuring the necessary level of rotational and quick-start reserve, compliance with the terms of the power purchase agreement, the issue of bidding in the power market, etc. In addition, the mobilizing power sources process and operating the power system must always aim at optimizing the cost of power production.
