At 15:36 on August 23, 2007, Xu Fushun, Vice Governor of Qinghai Province, issued the start-up command. Following established procedures, dispatchers ordered the 330 kV Mingzhu Substation to begin power transmission. The Xijin Chaidamu II Transmission and Transformation Project in Qinghai Province includes the construction of two new 330 kV substations—Mingzhu and Bayin—as well as a 772-kilometer transmission line at 330 kV running from Huangyuan to Mingzhu, then to Ulan, Bayin River, and finally to Golmud. Additionally, the project involves the expansion of three existing 330 kV substations—Golmud, Huangyuan, and Ulan—and the installation of five main transformers with a total capacity of 390 MVA. This project represents the largest and most challenging undertaking in the history of Qinghai’s power grid development. Once put into operation, the project will further enhance Qinghai’s main power supply.

This project represents the largest and most challenging undertaking in the history of Qinghai’s power grid development. Once put into operation, the project will further enhance the Qinghai main grid’s ability to transmit power to the western part of Qinghai Province and improve the reliability of power supply. It will also provide continued support for resource development in the Chaidamu region, ensure a reliable power supply for the Qinghai-Tibet electrified railway, and play a critically important role in promoting rapid resource development and economic growth in western Qinghai—and indeed throughout the entire province—during the 11th Five-Year Plan period.
