OREANDA-NEWS. June 14, 2013. Another “Heavenly Road of Electricity” has been built on the snow-covered plateau, which is bound to bring light to the people. On June 6, 2013, the 330kV Interconnection Project between Yushu grid and the state grid was put into trial operation, which took one year to construct. The project puts an end to the isolated operation of Yushu grid and solves the power shortage problem in that area once and for all.

The ceremony took place at the main venue of Qinghai Electric Power Company. Sub-venues were at Tangnaihe Substation, Maduo Switching Station, and Yushu Substation. Qinghai Provincial Party Secretary and Chairman of Standing Committee of Provincial CPC Luo HuiNing, Deputy Party Secretary of Qinghai and the Governor Hao Peng attended the event at the main venue. Standing Committee Member and Deputy Governor of Qinghai Luo Yulin and SGCC EVP Shuai Junqing presented at the main venue and delivered speeches.

This interconnection project is another major grid project of SGCC on the plateau after the Qinghai-Tibet ADC/C Interconnection Project. The project starts at Huangzhong County, Xining City in the north, and ends at Gyegu Township of Yushu Tibetan Autonomous Prefecture, waving its way through Xining, Hainan, Golog and Yushu. It the world’s highest 330kV transmission and transformation project, with an attitude of 3,200m to 5,000m. The project, with a total investment of 2.47 billion yuan, has built Tangnaihe 330kV Substation, Maduo 330kV Switching Station, Yushu 330kV Substation and the Riyue Mountain-Tangnaihe-Maduo-Yushu line. The total length is 803km.

The Yushu Interconnection Project is a civic project to ensure the post-quake reconstruction and the power supply for the socio-economic development in that area, promote national unity, and build a harmonious society. It is also a green project to promote the exploitation of hydropower resources and optimize resource allocation in a broader scope. The voltage of Yushu grid was upgraded to 330kV for the first time so the interconnection to other grids in Qinghai could be realized. It is certainly another milestone for the electric power development in Qinghai.

Luo Yulin extended his gratitude to SGCC on behalf of Qinghai Provincial Party Committee and the Provincial Government for its contribution to the Yushu Interconnection Project. He hoped that SGCC could intensify its support for Qinghai grid to accelerate UHV construction, support new energy, improve grid structure in the Tibetan area, and solve the power problems in areas without access to electricity as the province is advancing rapidly socially and economically. He also hoped that SGCC could optimize the grid structure in a broader scope, form a safe and reliable transmission/distribution system with an improved layout, rationalized structure, close connection, and urban and rural coordination, providing strong power support for the development of Qinghai.

Shuai Junqing said this project was an important measure of SGCC to implement the deployment of the CPC Central Committee and Stat Council and to promote the socio-economic development in Qinghai. The construction was quite difficult due to geological complexity, widespread permafrost, severe cold, and lack of oxygen. Therefore, the mission was an honor. During the construction, SGCC gave full play to the conglomerate operation and intensive management, standardized the construction, and combined specialized project management with localized project construction. All construction workers have ensured hardships and difficulties to complete a safe, reliable, quality, efficient, and green project with high standard, high efficiency and high level within a year.

SGCC Assistant President and Director of Northwest Branch Chen Xiaolin presided the event at the main venue. SGCC Deputy Chief Engineer Li Wenyi attended the ceremony at the main venue.

It is learned that the Yushu Interconnection Project will send electricity to 110kV Gyegu Substation through two connecting lines once it is put into operation and the electric power from the big grid will be delivered to households through the existing Yushu-Chindu-Nangqen Zong Interconnection Project and the distribution network.
