South China Power Grid's electricity load has reached a new high for four consecutive days, breaking the seasonal pattern.

Summary of Key Points

Recently, the electricity demand in the Southern Power Grid (covering Guangdong, Guangxi, Yunnan, Guizhou, and Hainan provinces) has continuously reached new highs. Not only did this happen earlier than in previous years (the peak used to occur in June or July, but this year it was frequently broken in May), but there has also been a new trend of particularly high demand during the evening hours. The reasons include an earlier onset of hot weather, full-capacity industrial production, and a surge in electricity consumption from emerging industries such as data centers and new energy vehicles. These factors have combined to shift the electricity demand pattern from a single peak during the day to three peaks throughout the day. Although the power supply remains stable for now, the Southern Power Grid has already activated its summer power supply assurance measures.

1. This year's peak demand came earlier, with more record-breaking occurrences

In previous years, the annual peak in electricity consumption for the Southern Power Grid usually occurred in June or July, but this year it happened as early as May. From May 25 to 28, the load reached new highs for four consecutive days, reaching a maximum of 275 million kilowatts. On May 28, the Guangdong power grid hit its second highest level of the year (170 million kilowatts), while Guangzhou and Shenzhen experienced their first record-breaking peaks of the year. The Guangxi power grid also reached its fifth peak of the year. In total, since the beginning of the year, there have been over 20 instances of breaking electricity consumption records across the entire network and the five provinces, completely disrupting the previous seasonal patterns.

2. Why did the peak come earlier? A combination of high temperatures, industrial activity, and new industries

Manager Li Zhiyong from China Southern Power Dispatching explained that three main factors contributed to this:

1. Earlier hot weather: This year, the heat in South China arrived earlier than usual, leading to an increased use of air conditioning and a surge in electricity consumption for cooling.

2. Uninterrupted industrial production: Factories are operating at full capacity, resulting in a steady increase in industrial electricity demand.

3. Strong consumer demand: People are using more electricity for their daily needs than before.

3. Electricity consumption from new industries has skyrocketed, with data centers and new energy vehicles being the most significant

The data is quite telling:

  • Guangdong: From January to April, electricity consumption by data centers increased by 18.48%, and high-tech manufacturing by 8.51%.
  • Guangxi: Electricity consumption by 36 key monitored data centers increased by 19.2%, while the production of new energy vehicles surged by 277.9% (almost tripling), and the lithium battery industry grew by 17%.
  • Shenzhen Guangming District: As a hub for data centers, electricity consumption there increased by 85.31%. These new industries operate around the clock, significantly contributing to the high demand during evening hours.

4. Changes in electricity demand patterns: From a single peak during the day to three peaks throughout the day

Previously, industrial electricity consumption was the main driver of peak demand, which mainly occurred during the day. However, now services (such as data centers and the internet) and residential electricity use are accounting for an increasing proportion. Additionally, residents charging new energy vehicles at night also contributes to peaks in the morning, noon, and evening, creating a new pattern with three distinct peaks. This means that the rules for power supply management have completely changed, making it more complex.

5. Pressure to ensure supply has increased, and the Southern Power Grid is already taking action

Although the current power supply is stable, the Southern Power Grid has initiated its summer power supply assurance measures in advance to prepare for the expected peak demand. This includes potentially increasing power generation capacity, optimizing grid operations, and ensuring that key users have access to electricity. With these measures in place, there should be no major issues with electricity supply.

In summary, the earlier peak this year reflects two trends: changes in weather (earlier hot seasons) and shifts in the economic structure (an increase in electricity consumption from new industries). For consumers, it may seem like summer has arrived early due to more frequent use of air conditioning, but this is a sign of economic vitality and industrial development. As long as the supply assurance measures are effective, there should be no significant problems with electricity availability.
