In the past 10 years, the total investment in power grid construction in the Wenchuan earthquake-stricken area has reached 60.6 billion yuan, and the number of substations has increased from 385 to 728, which is 1.89 times before the earthquake. The maximum power load in the disaster area has increased from 4.39 million kilowatts to 9.35 million kilowatts. The previous 2.13 times; the annual electricity consumption in the disaster area increased from 26 billion kWh to 54.9 billion kWh, which was 2.11 times before the earthquake; the country's leading power emergency response system was built.
“It can quickly collect parameters and improve work efficiency.†On the afternoon of May 10th, a smart inspection robot was conducting daily inspection and maintenance work at the 220kV substation of Ertaishan. According to Luo Liang, chairman and general manager of State Grid Sichuan Abazhou Electric Power Co., Ltd., the substation was formerly known as the 220kV switchyard of Yingxiuwan Power Plant, which was devastated during the “5.12†Wenchuan earthquake. After 9 months, the State Grid Sichuan Electric Power Company rebuilt the original site and upgraded it to a substation.
It is reported that this is the first substation used in the reconstruction of Aba Prefecture after the disaster. Ten years ago, the Wenchuan earthquake hit Sichuan Power Grid. 171 substations and 2,751 transmission lines in our province were shut down. Some of the power grids were destroyed, 4.05 million households were cut off, and direct economic losses amounted to 10.6 billion yuan.

Scientific reconstruction of power grids in disaster areasAfter the earthquake, State Grid Sichuan Power restored the power supply at the fastest speed. Under the support of the State Grid Corporation and the counterpart support of the brother network company, the grid was reconstructed according to local conditions and achieved leapfrog development.
In the past 10 years, the Wenchuan earthquake-stricken area has completed the investment of 60.6 billion yuan in power grids, newly built and expanded 396 substations of 35 kV and above, newly added capacity of 53.45 million kVA, and added 12762 km of transmission lines of 35 kV and above. The power grid assets in the disaster area increased from 14.643 billion yuan to 46.858 billion yuan, 3.2 times before the earthquake; the number of substations increased from 385 to 728, which was 1.89 times before the earthquake; the capacity was changed from 25.07 million. The kilovolt-ampere increased to 78.57 million kVA, which was 3.12 times before the earthquake; the length of the line increased from 21,000 km to 33,900 km, which was 1.62 times before the earthquake. The power supply capacity, power grid structure and technical equipment level of the power grid in the disaster area have been greatly improved, and the ability to withstand natural disasters and power supply support has been significantly improved.
At the same time, State Grid Sichuan Electric Power actively implemented special policies such as direct purchase of electricity, surplus electricity, retained electricity, and temporary price hikes in the disaster areas to benefit the people and support the development of key industrial parks such as Aba and Guangyuan. It received 8 million resident customers of local power grids and small hydropower supply areas, and developed 9.5 million new residential customers. State Grid Sichuan Electric Power has donated more than 8.6 million yuan for post-disaster reconstruction and love support.
In Chengdu, the State Grid Chengdu (Dujiangyan) Communist Party Service Team set up a pledge of "27 people to fight to 40 people" on the ruins of the earthquake. Chengdu Power Grid quickly grew into a 600-kilometer volt with a weak body. Substation, double-loop network operation, power grid scale, equipment quantity and technical level are all in the forefront of the provincial capital cities.
In Deyang, Deyang Power Grid and Deyang Industrial have experienced heavy losses, recovery and rise. State Grid Deyang Power Supply Company helped a number of leading enterprises such as Dongqi and Hongda Group to emerge from the disaster and implement the “Kangqiao Project†and “Rainbow Projectâ€. The 6.4 billion yuan investment in power grids provided energy security for Deyang's industrial economic development.
In Mianyang, the country’s first 110 kV smart substation was launched as a landmark project for post-disaster reconstruction in Beichuan. Wang Zhigang, an electrician from Beichuan, lit up the lights of the villagers in the village, and sent power to the Tibetan compatriots, moving China.
In Guangyuan, the 500 kV substation was built from scratch, the structure of Guangyuan Power Grid was stronger, the power supply capacity was tripled, and the reform dividend was released. The city's 1.7 million urban and rural residents realized the same price on the same network.
In Aba, in the past 10 years, a total investment of 9.58 billion yuan has been built to build a strong grid with 220 kV and 110 kV as the backbone, providing power protection for post-disaster reconstruction. The implementation of the "warm Tibetan mastiff" project will effectively guarantee power supply in remote areas and promote economic development and national unity.
The disaster-prone Yingxiuwan power plant was damaged twice and rebuilt twice. The power station realized remote centralized control. The safety production and operation management exceeded the pre-earthquake level, and the power generation reached the best level in history, realizing the rebirth from desperation to revitalization. The leap.

The nation's leading power emergency system constructionAfter the 5.12 earthquake, after ten years of hard work, State Grid Sichuan Power has built a leading electric power emergency system in the country. The power emergency capability has been experienced and matured in many natural disasters such as the Lushan earthquake, the Jiuzhaigou earthquake, and the Maoxian landslide. It has achieved unified command, complete functions, responsiveness and efficient operation.
The system has built three levels of power emergency command centers at the provincial, prefecture and county levels, forming a command system covering the whole Sichuan, connecting up and down, interconnecting and interoperating, and establishing a coordinated mechanism of politics, enterprises and regions, equipped with “high-precision†emergency rescue equipment. Create a three-dimensional rescue mode of “water, land and airâ€. Emergency technologies such as “3D Combat Command Deduction Roomâ€, “4D Disaster Experience Roomâ€, “High Altitude Emergency Survey and Inspection†and “High-altitude Transmission Line Emergency Rescue†have made breakthroughs.
In the past 10 years, State Grid Sichuan Electric Power handled 962 emergencies of various types, initiated 26 emergency response at the company level, accumulatively invested 337,700 emergency rescue personnel, and dispatched 32,600 emergency vehicles. Standardization and team of emergency systems The specialization and synergy linkage mechanism is scientific, the modernization of equipment and material security is improving day by day, the emergency system construction and actual combat capability are at the leading level in the national power industry, and the goal of “the world-class electric power emergency system†is continuously advanced.
