High voltage AC and DC construction will accelerate

In January 2012, the 2012 work conference of the State Grid Corporation of China was held in Beijing. Deploy key tasks in 2012, comprehensively deepen the "two transformations", speed up the construction of a "strong and three excellent" modern company, create a world-class power grid, a world-class enterprise, and serve the economic and social development.

The general manager of the company, Liu Zhenya, stated that the national examination and approval work for a group of UHV power transmission projects has been difficult to promote and has become a bottleneck restricting the development of power grids. In 2012, the company will ensure that a number of UHV projects are approved or started construction. Concentrate on promoting the UHV preparatory work to ensure that 4 UHV AC projects and 3 UHV DC projects have been approved and commenced by the State. In addition to this, UHV AC projects and 1 UHV DC project will be pursued. Approved during the year. Liu said that the next step is to work hard to promote the company's five-year power grid planning into the country's "12th Five-Year Plan" special network planning, and strive for early approval of the UHV project, early construction, early network, play a role as soon as possible.

In 2012, the State Grid Corporation of China will complete investment in fixed assets of 336.2 billion yuan, of which 309.7 billion yuan will be from the grid. 16,000 kilometers of 110 (66) kV and above AC lines, 3.6 billion kVA of transformer capacity, 6,146 kilometers of DC lines, and 51 million kilowatts of commutation capacity; and 57,000 kilometers of 110 kV and above AC lines 260 million kVA of variable capacity, 2,095 km of DC lines, and 14.4 million kilowatts of commutation capacity. Electricity sales amounted to 3,700 billion kwh, an increase of 9%; the national power market traded 416.5 billion kwh, an increase of 4.1%. At the same time, State Grid Corporation of China has built a number of demonstration projects for charging and exchanging electric vehicles in Beijing, Suzhou, Shanghai, and Qingdao. There are 156 new charging and switching stations and 6,252 charging stations.

In 2012, the growth rate of State Grid’s investment slowed to 3%. From the perspective of the rapid growth of line length, substation capacity, and converter capacity, the structural opportunities remain. The State Grid will push forward the construction of UHV AC and DC and maintain the investment climate of distribution network.
