This summer, a relentless succession of heatwaves and brief, intense rainstorms coincided with a booming tourism economy and full-throttle operation of local specialty industries, pushing the city's grid electricity load to repeated record highs. State Grid Qinhuangdao Power Supply Company has anchored its response in meeting the needs of daily life and urban development, leveraging a robust grid as its foundation, technological innovation as its engine, and precise services as its core tool. By weaving a tight-knit power supply security network, the company is fully committed to safeguarding stable urban electricity, flourishing cultural tourism, and increased industrial income, ensuring the smooth and stable operation of the city's summer economy.

On August 26th, in the Liuzhuang Homestay area of Beidaihe District, staff from the Beidaihe Power Supply Center of State Grid Qinhuangdao Power Supply Company were meticulously inspecting distribution boxes, meter boxes, and other equipment. They worked alongside users to check indoor wiring, switch leakage protection devices, and other facilities, while also providing on-the-spot guidance on safe electricity usage. Responding swiftly to merchants' requests for increased power capacity, the team processed the full range of electricity service procedures in a closed loop, fully meeting the operational electricity needs of businesses during the peak tourist season. Tourist Liu Xin remarked, "I just checked in today and happened to meet the power staff who came to inspect the lines. They were very thorough, and we feel completely at ease with the electricity here."

Behind this high-quality service lies the strong support of a resilient power grid. During the tourist rush, the booming catering, homestay, and other cultural tourism businesses led to the concentrated use of various high-power appliances, causing a significant surge in regional electricity load and imposing higher demands on supply stability and safety. Focusing on the electricity needs of the city's cultural tourism operators, State Grid Qinhuangdao Power Supply Company optimized its summer supply service plan, implementing a model of "dynamic monitoring plus door-to-door service." The company conducts routine specialized inspections of electricity use for merchants in the area, effectively guaranteeing stable and reliable power for the cultural tourism market.

While strengthening the hardware foundation, State Grid Qinhuangdao Power Supply Company has also been deepening its development of smart grid infrastructure. The cable tunnel, a critical underground component of the power supply network, presents challenges such as a hot and humid environment, a tendency for harmful gases to accumulate, and complex terrain. Traditional manual inspections are time-consuming, labor-intensive, and carry high operational risks. To address this, the company has innovatively introduced a four-legged intelligent inspection "robot dog" to fully replace manual patrols for routine cable tunnel checks. Equipped with high-precision sensors, the "robot dog" autonomously adapts to complex terrains, accurately performing tasks such as gas detection, temperature measurement, and line inspection, while transmitting data back in real-time. This achieves intelligent operations for high-risk tasks and precise hidden danger identification. Huang Haiwen, an employee at the company's Cable Operation and Inspection Center, noted, "With the cable inspection 'robot dog,' we can now assign inspection tasks remotely. It replaces manual patrols and repairs, reducing each operation's time by more than 40 minutes while enhancing personnel safety."

Simultaneously, State Grid Qinhuangdao Power Supply Company continues to upgrade its digital and intelligent operation and maintenance systems. By optimizing the functions of its transmission monitoring center and integrating over 7,000 line monitoring camera devices, the company has achieved 24-hour intelligent monitoring, identification, and early warning for hazards like mountain fires and external damage from construction. To tackle the challenges of complex terrain and difficult manual line patrols in the Qinglong mountainous area, an innovative joint inspection model for transmission and substation facilities has been established. Multiple intelligent inspection drone nests have been deployed, and cross-professional data platforms have been connected. Drones, maintenance personnel, and civilian line guards work together in an integrated air-ground inspection system, moving safety control to the forefront and shifting from post-incident handling to pre-incident prevention and in-process management.

Facing the unpredictable weather tests of the flood season, State Grid Qinhuangdao Power Supply Company strictly enforces a 24-hour leadership duty system, with all types of repair teams on standby. Comprehensive hazard surveys are conducted across the city's key substations, transmission lines, and distribution rooms. Repair materials and emergency equipment are pre-positioned in areas prone to mountain floods. During heavy rainfall, staff remain on the front lines of flood prevention and power protection, focusing on inspecting power facilities near riverbanks and reservoirs to ensure stable power supply at temporary resettlement sites. Following the principle of "restore power first, repair later," the company minimizes the impact of severe weather on people's daily electricity use.

In addition to safeguarding cultural tourism and people's livelihoods, State Grid Qinhuangdao Power Supply Company precisely empowers the development of local specialty industries. Responding to the electricity needs of industries like grape cultivation in Lulong and wine processing in Changli, a customized "one county, one policy" service has been implemented. Leveraging a "village-grid co-construction" service model, convenience service points have been established in planting areas. During key phases of grape fruiting, harvesting, and winemaking, routine "electrical check-ups" are conducted to identify and resolve hidden dangers in greenhouse temperature control, irrigation equipment, and winery production lines. The company also upgrades rural grid infrastructure, providing comprehensive support for the steady growth of local specialty industries.

During this year's tourist season, from bustling cultural tourism districts to rural industrial fields, from intelligent technology inspections to frontline emergency power protection, State Grid Qinhuangdao Power Supply Company has used technology to enhance grid resilience and warm-hearted service to fulfill its corporate responsibility. Through dedication and practical action, it has fortified the power grid's safety defense line, injecting reliable electric momentum into the city's high-quality development.
