The controversial conclusions of the issue of UHV construction are emerging. The national Power Grid Corp issued a message yesterday that the 1 million volt Huainan Nanjing Shanghai UHV exchange project was approved by the national development and Reform Commission. The 12 transmission channels that the state is about to approve, including 4 UHV AC projects of the national Power Grid Corp and 4 UHVDC projects, will be approved by the state.

Huainan - Nanjing - Shanghai UHV AC line became the first approved UHV line in the year. Industry insiders believe that this means that the long - debated UHP exchange project will break the ice. Relative to the DC UHV, AC UHV is more controversial because of security and economic considerations.

The initial investment of Huainan - Nanjing - Shanghai AC UHV (North Ring Line) was about 26 billion 100 million yuan.

Recently, media reports reported that a power grid investment plan developed by the electric power planning and Design Institute has passed the evaluation of China International Engineering Consulting Company and will soon be approved by the national energy administration.

Reported that this scheme involves the investment of more than 200 billion yuan, including the construction of transmission channel 12 through China East, which contains 4 UHV AC project, 5 UHV DC project, and 3 + 500 thousand volt transmission channel, the transmission of electricity resources in Inner Mongolia, Shanxi, Shaanxi and Yunnan and other places to the Beijing Tianjin Hebei, Yangtze River Delta and Pearl River Delta region, in order to solve the haze and power shortages in these areas increasingly serious.

In these UHV projects, there are 4 communication projects and 4 DC projects involved in the national network. It includes the Huainan Nanjing Shanghai UHV exchange project approved by the State Energy Bureau in April 21st. The industry is expected throughout the year there will be Ya'an, Ximeng - Wuhan - Shandong AC line will be allowed to formal construction; DC, the probability of Jiuquan - Hunan, Ningdong - Zhejiang UHV was also larger.

The issue of UHV is also becoming more and more clear with the release of management. In 2014, the national grid will focus on building 27 UHV lines has been completed and put into operation: including "two pay three straight project, approved in the construction of the" cross "project, obtain Lutiao three pay three straight project and several other projects into the national air pollution control plan.

In April 18th this year, the first meeting of the new National Energy Commission, Premier Li Keqiang explicitly proposed to accelerate the adjustment of energy structure, the implementation of cross transmission projects, the development of long-distance high-capacity transmission technology; according to the planning to start the construction of a group using conventional techniques and UHV power transmission from West to east transmission channel, optimizing the allocation of resources, promote energy efficiency. This is also since the standing meeting of the State Council in February 12th this year proposed the "implementation of the cross district power supply project", the high rise again on the high voltage technology.

Guotai Junan Securities said that the government's determination to optimize the energy structure and balance supply and demand has become the core driver of the comprehensive outburst of UHVDC and intra network communication in 2014. In 2015, it will continue to grow at a high speed. The UHV approval normalization will become clearer.
