en.Wedoany.com Reported - Since May 27, the power load of Guangdong Power Grid has hit record highs three times this year, reaching a peak of 173.67 million kW, a 5.3% increase from last year's peak load, making it the first province in China this year to exceed 170 million kW in load. Multiple cities within the province have also set new load records simultaneously. For instance, the Guangzhou Power Grid load hit new highs twice on May 28 and 29, climbing to 25.946 million kW, a 3.33% increase from last year's peak load. Despite consecutive heavy rains in the past two days, the high temperatures across the province remain unabated, driving strong electricity demand. China Southern Power Grid Company has been fully committed to ensuring power supply during the peak summer period, from grid reinforcement and digital intelligence empowerment to frontline duty.
To fortify the summer power supply defense, the Guangzhou Power Supply Bureau of China Southern Power Grid Guangdong Company completed and commissioned 827 distribution network summer projects across the city before April 30, with a total investment of 989 million yuan, adding 616,800 kVA of distribution capacity, focusing on weak power supply areas such as urban villages and old residential communities. The Guangzhou Power Supply Bureau has formulated a three-year task list for village-level distribution network construction land, incorporating 1,092 plots of land into the grid construction task list on an annual basis, collaborating with local governments to address grid construction issues.
In densely populated urban villages with concentrated rental housing, such as Kanglu, Lijiao, and Tuhua in Haizhu District, the Haizhu Power Supply Bureau of China Southern Power Grid Guangdong Company has strengthened the power supply hardware foundation by promoting transformer capacity expansion, equipment deployment, and upgrading old lines, while implementing hazard management and refined operation and maintenance. It has also established normalized coordination mechanisms with local streets and village communities to promptly respond to residents' electricity needs. Currently, this governance model has been adapted and promoted in districts such as Tianhe, Baiyun, Panyu, and Huangpu based on local conditions.
In Nanhe Village, Suixi Town, Zhanjiang, four 630 kVA transformers frequently exceeded their limits during peak hours, but narrow village lanes prevented large power generation vehicles from entering. The Party member commando team of the Zhanjiang Power Supply Bureau of China Southern Power Grid Guangdong Company utilized idle homestead land in the village to set up temporary power supply points and deploy temporary transformers, completing and commissioning an emergency station within a day, effectively diverting the load from the original transformers. The Jieyang Power Supply Bureau of China Southern Power Grid Guangdong Company focused on 11 distribution areas prone to faults during the peak summer period, addressing existing issues through distribution network renovation, transformer capacity expansion, load optimization and reconnection, and three-phase imbalance management, while implementing a "one village, one WeChat" service model.
In terms of digital intelligence empowerment, the "Distribution Network Repair Commander Intelligent Agent" independently developed by the Guangzhou Power Supply Bureau has been fully deployed across the city. This system integrates multi-dimensional spatiotemporal data such as grids, equipment, addresses, coordinates, and users, enabling precise identification of 77 types of risk targets, achieving second-level perception of line faults. The fault diagnosis time has been reduced from the traditional manual 15 minutes to an automatic response of 1 minute, improving disposal efficiency by over 90%. To date, this intelligent application has accurately identified 1,347 faults.
On the frontline of power supply, Li Dahua, an employee of the Jinji Power Supply Station of the Kaiping Power Supply Bureau of China Southern Power Grid Guangdong Company, discovered during a visit that the 10 kV Gaoxi public distribution area was overloaded due to insufficient transformer capacity and rising loads during the peak summer period, resulting in low voltage at night that could not power air conditioners. He worked for over four hours under the scorching sun that afternoon to replace the old transformer with a new one, and immediately notified residents after successfully restoring power in the evening. Zheng Qiongyi, captain of the "Island Light Cavalry" Party member service team of the Nan'ao Power Supply Bureau of China Southern Power Grid Guangdong Company, led team members using infrared thermometers to conduct temperature measurement and inspection of distribution transformers and line connectors in the area, utilizing nighttime high-load periods to identify hidden heating and overload issues.
