Lingshan Island is covered in green grass, lush trees, singing birds, and fragrant flowers in the summer. The sound of laughter resounds endlessly, and most of the tourists on the island come to see the  "carbon-negative sea island".
 

 
How did they achieve “Carbon-Negative”?

Carbon emission reduction is not an easy task, and the core of it is “electricity”. To change the way of life and production of the islanders, it is important to ensure that the island has a safe and reliable power supply.

To protect the safe and reliable operation of the island power supply, the State Grid Qingdao Huangdao District Power Supply Company developed an innovative Submarine Cable Inspection Robot, which has increased inspection efficiency from the traditional 0.2 kilometers per hour to 3.2 kilometers. This changed the “fault repair” of submarine cables to “full monitoring.”

In addition, since 2020, the State Grid Qingdao Huangdao District Power Supply Company has fully implemented the Lingshan Island distribution network renovation project, completing 12 low-voltage substation upgrades and replacing 7.8 kilometers of overhead wires.
 
What are the benefits of “Carbon-Negative”

The “Carbon-Negative” sign has promoted the steady improvement of Lingshan Island’s cultural tourism industry, forming a tourism aggregating effect.

To ensure reliable power supply throughout the tourist season, Gu Yongjun, Miao Zaiwei, and Xiao Yonglei, grid managers of the Qingdao Huangdao District Power Supply Company of SGCC, carry out safe electricity inspection at each hostel every day before the peak of electricity consumption, helping to timely eliminate hidden dangers.
 
This year marks their 33rd year working on the island. “We are busier during the tourist season. It is hard, but we can see the whole island becoming more and more beautiful, and everyone's life getting better and better and that makes it all worth it, and we all feel proud of the work.” Gu Yongjun said.
