Multi-Scenario Sharing of Enterprise-Level "Power Banks"

 (Lianyungang Power Supply Branch of State Grid Jiangsu Electric Power Co., Ltd.)

Large-scale mobile energy storage equipment (energy storage vehicles) offer significant advantages in resolving the conflict between enterprises’ fluctuating electricity consumption for production and transformers’ fixed power supply capacity. However, such enterprise-level shared "power banks" still remain a commercial blank. The Lianyungang Power Supply Branch accurately identified the development trend of the mobile energy storage industry, innovatively promoted market cooperation models, and took the lead in standardizing interface protocols. It also expanded various application scenarios such as regular over-capacity electricity use and emergency backup power supply, achieving the commercialization of enterprise-level "power banks."

Promoting Energy Consumption Transformation to Support the Rapid Development of NEVs

(Wuxi Power Supply Branch of State Grid Jiangsu Electric Power Co., Ltd.)

The robust growth and large-scale development of new energy vehicles(NEVs) in China have impacted grid load, power supply quality, and electricity trading. The Wuxi Power Supply Branch implemented incentive measures such as peak-valley electricity pricing for NEV owners, encouraging them to charge during off-peak grid hours and discharge to the grid during peak hours to gain benefits. This approach transforms vehicles from energy consumers to energy producers, alleviating grid supply pressure and enhancing peak-shaving capacity. It supports the rapid development of NEVs.

✅ Green Grids Sustain Ecological Splendor

Enterprise-Government-Public Collaboration in Windbreaking and Sand Fixation: Writing a Green Legend of "West-East Electricity Transmission"

(Ultra-High Voltage Company of State Grid Ningxia Electric Power Co., Ltd.)

Approximately 20% of the towers in the Ningxia section of the ±660 kV Yindong HVDC transmission project are located in desert areas. Sand damage not only threatens the safe operation of the power lines but also inconveniences local production and daily life. Since 2012, State Grid Ningxia Ultra-High Voltage Company has collaborated with local governments and communities through a "tripartite collaboration" model—joint assessment, joint governance, and joint maintenance—to combat desertification and stabilize sand. This effort has transformed the desert beneath the power lines into an oasis, enhanced local biodiversity, and supported regional ecological conservation while ensuring the stable transmission of green and clean energy.

✅ Engaging in Social Governance to Tackle Complex Challenges

"Rescue Power Towers" Establish Wild Escape Routes

(Ultra-High Voltage Branch and Shaoxing Power Supply Company of State Grid Zhejiang Electric Power Co., Ltd.)

In collaboration with emergency management agencies, social rescue organizations, and other stakeholders, and leveraging existing power corridors and visual monitoring devices along transmission lines, a "Wild Emergency Rescue Alliance" has been established. This network uses the main control room of an ultra-high voltage station as the "rescue center," connects 45,000 high-definition "sky eye" monitoring devices on power towers as the medium, and designates rescue power towers as support points. The alliance has created four major application scenarios, eliminated communication dead zones in remote areas and solved the challenge of "difficult positioning," reducing the average wilderness rescue time from 2-5 days to as little as 4-8 hours.
