On February 2, 2023, the Zhaowen 220 kV power transmission and transformation project of State Grid Weihai Power Supply Company officially started construction. This is the first power transmission and transformation project newly started by State Grid Shandong Electric Power Company in 2023. The project substation is located at the intersection of Hushan Road and Xiushan East Road, Wendeng District, Weihai City, Shandong Province, about 37.5 kilometers south of Weihai City and 7.7 kilometers southeast of Wendeng District, covering an area of 16.3 acres. There are 4 outgoing lines of 220 kV, 8 outgoing lines of 110 kV, and 24 outgoing lines of 10 kV. It is planned to be completed and put into operation in March 2024.

Sui Shiyan, safety officer of the Zhaowen 220 kV power transmission and transformation project construction project department, told reporters: "After the project is put into operation, the power supply mode of dual 220 kV substations in Wendeng City will be realized, and the power supply capacity of the city will be doubled. At the same time, substations and related users in the region also have a reliable second power point, which can significantly optimize the regional grid structure and improve power supply capacity and reliability."

In 2023, State Grid Shandong Electric Power will further increase the construction of power grid projects, and the investment in power grid infrastructure of 35 kV and above will hit a new high. It plans to start 2,886 kilometers of new lines and 24.99 million kVA of transformation capacity; With a capacity of 26.47 million kVA, it will focus on promoting the construction of 17 UHV and EHV projects, including Longdong to Shandong DC, to help Shandong replace old and new kinetic energy, optimize energy transformation, and provide safe, reliable and high-quality power guarantee for Shandong's economic and social development.
