The National Energy Administration held emergency drills for large-scale power outages across provinces and regions in Shanghai for the first time. Provincial | East China | National Energy Administration
In order to enhance the emergency coordination ability across provinces and regions, and to do a good job in responding to power emergencies during important periods such as peak summer, today, the National Energy Administration held an emergency drill for large-scale power outages across provinces and regions in the East China region. This is the first time that the National Energy Administration has held an emergency drill for large-scale power outages across provinces and regions, and it is also the largest, most extensive, and most targeted joint emergency drill conducted so far for public power emergencies.
The East China Power Grid is the largest and highest voltage level regional power grid in China. In the summer of 2023, the maximum electricity load of the East China Power Grid is expected to be 397.25 million kilowatts, and the situation of ensuring safety and supply of the power grid is relatively severe. Meanwhile, as a typical receiving power grid, the power balance of the East China Power Grid highly relies on external electricity. In the summer of 2023, it is expected that the external electricity in the area will be about 70 million kilowatts, accounting for approximately 18% of the highest load on the power grid. Once catastrophic weather occurs, it may cause large-scale power outages that have a serious impact on social and economic development and people's lives.
This drill focuses on the operational characteristics and main safety risks of the East China Power Grid. It simulates a large-scale power outage in four provinces and one city of East China during this year's peak electricity summer season. After the incident, the National Energy Administration coordinates and guides the power management departments, energy regulatory agencies, and power enterprises of various provinces and cities to initiate emergency response, carry out cross provincial and cross regional power emergency support, and jointly respond to and handle the sudden large-scale power outage in the power grid in accordance with the National Emergency Plan for Large Area Power Outages. The drill includes five stages: monitoring and early warning, early response, emergency response initiation, emergency response, and emergency closure. There are nine drill subjects, including early warning release and action, early response by power grid enterprises, emergency response initiation by relevant units, social emergency linkage in Shanghai, cross provincial and regional power support, emergency repair of transmission channel faults, and partial power grid restoration. In addition to severe faults caused by typhoons and heavy rainfall in the transmission channels of the East China Power Grid, the scenario settings also include power plant transmission line faults, new energy disconnection, and cross regional DC blocking. The drill also set up scenarios for power outages among multiple important power users in Shanghai and social emergency response, highlighting the orderly implementation of social emergency response by the Shanghai Municipal Government as the leading department for large-scale power outages, reflecting the emergency response linkage between the power industry and local governments, and further enhancing the practical and guiding significance of the drill.
