It is not appropriate to build power plants in central and eastern China

: [CCTV Finance Channel] On January 14th, 2012, in the economic information network, "The East and West should not build power plants to continue UHV transmission and electrolysis," and the news shows that China's first UHV transmission project has successfully expanded, marking UHV. The technology of power transmission has gradually matured. At present, the scale of thermal power in the central and eastern regions of China has reached the limit of environmental carrying. There is an urgent need to optimize high-voltage transmission over long distances to optimize the energy supply structure and reduce environmental pressure.

The successful expansion of China’s first UHV transmission project in recent days signals that the technology of UHV transmission has become more mature. At present, the scale of thermal power in China's central and eastern regions has reached the limit of environmental carrying. There is an urgent need to optimize high-voltage transmission over long distances to optimize the energy supply structure and reduce environmental pressure.

The latest environmental monitoring from the Ministry of Environmental Protection shows that at present, 104 acid rain cities nationwide are located in the central and eastern regions, and the sulfur dioxide emissions of the central and eastern units are 5.2 times that of the west. This means that there is basically no environmental space for the development of coal and electricity in the central and eastern regions. The State Council has made it clear in recent days that it has implemented total coal control in the Yangtze River Delta, the Pearl River Delta and the Beijing-Tianjin-Henan region to limit pollution.

Zhang Zhengling, deputy director of the State Grid Development and Planning Department, said: “On the coast of the Yangtze River, there is a power plant for every 30 km and a power plant for almost every 10 km in the local section of Jiangsu. The density is very large, with 55% of the country’s Electricity is distributed in the central and eastern regions."

Some experts said that the central and eastern regions are in urgent need of long-range high-voltage transmission lines to ease the strained power shortage. According to the national grid plan, during the 12th Five-Year Plan period, three vertical and three horizontal cross-country high-voltage exchanges and 16 zones will be constructed. The HVDC transmission project connects large energy bases and major responsible centers. Formed a large-scale transmission of electricity from west to east, and the distribution of energy from north to south.

The so-called three vertical and three horizontal lines, namely, the East Vertical Tin Alliance to Nanjing, the Middle Zhangbei to Nanchang, the West Longitudinal to the west of Changsha, the north to the north to the Weifang, the middle Jingjing to Lianyungang, and the south to Ya'an to Shanghai. A total of six test high voltage AC transmission lines. At present, the project already has conditions for starting work and is waiting for approval from the country.

“If we do not accelerate the start of construction and speed up the construction, it may be that our country’s recent years and year-after-year difficulties that have plagued coal-to-electricity transportation in central and eastern China will continue.” said Zhang Zhengling, deputy director of the State Grid Development and Planning Department.
