Transmission Channel Gaming: Southern Electricity Desolation Inner Mongolia Electric Power

In the south, it is possible to usher in the worst electricity shortage since 2004, and Inner Mongolia is making a diametrically opposite scene.

CEC expects that the electricity gap during peak hours in China this year will reach 30 million to 40 million kilowatts. At the same time, Inner Mongolia, where energy is so important, has experienced litter electricity due to delays in the construction of power transmission channels.

According to the Inner Mongolia Economic and Information Technology Commission, as of April, the surplus power supply capacity of the power grid in Mengxi was about 6.4 million kilowatts, while the installed growth rate in the Mengdong region was 2.07 times faster than the increase in electricity demand.

A large amount of electricity needs to be sent out, but not only the delivery capacity is limited, even if the existing transmission lines, due to lack of profitability and inter-provincial scheduling problems, the utilization rate of the Mengdong's outward transmission channels has only reached 60%.

In this regard, Inner Mongolia hopes to speed up the approval and promotion of the transmission grid project, and at the same time accelerate the construction of wind power supporting power and launch a number of thermal power projects.

However, this is inconsistent with China's energy structure adjustment in recent years, especially the energy policy that controls total coal consumption. Regional energy endowment differences make a new round of competition between the national energy policy and local development enthusiasm, energy surplus regions and energy shortage regions, and power grids and power generation companies.

Electric Inner Mongolia

“In Inner Mongolia, coal cannot be transported and electricity cannot be delivered,” said Zhang Fusheng, general manager of Inner Mongolia Electric Power Group.

"Inner Mongolia has the ability to support the country's energy needs," said Zhao Gang, deputy director of the Energy Development Bureau of Inner Mongolia Development and Reform Commission. He said that Inner Mongolia had 600 million tons of coal production capacity and 150 million kilowatts of coal-fired power projects in the early stage of its work. Since the beginning of the “Eleventh Five-Year Plan” period, it has started to build new special coal transportation lines and transmission channels, but it has not obtained approval from the state. The phenomenon of electricity. "This is considered by the country, and we are anxious to use it," said Zhao Gang.

However, despite the phenomenon of litter, Inner Mongolia is still the region with the largest amount of electricity sent by China. Last year, Inner Mongolia sent 106.4 billion kWh of electricity. In the first four months of this year, Inner Mongolia has sent a total of 39.8 billion kilowatt-hours of electricity outside the area, an increase of 10.84% ​​over the same period last year.

According to Zhang De, director of the Energy Division of Inner Mongolia Economic and Information Commission, the growth rate of installed capacity in Inner Mongolia exceeded the national average in recent years. At the end of 2010, Inner Mongolia’s installed capacity of electricity reached 64.58 million kilowatts, of which thermal power installed capacity was 54.06 million kilowatts, wind power was 9.68 million kilowatts, and hydropower was 844,000 kilowatts. From the distribution point of view, the installed capacity of Mengxi is 48.99 million kilowatts, and the installed capacity in Mengdong is 15.59 million kilowatts. In Inner Mongolia, there are currently 10 outward-produced passages with an output capacity of 26.2 million kilowatts.

“The power supply exceeds demand in Mengxi Power Grid, and some of the thermal power plants have surplus capacity and wind power output is hindered.” Zhang De said, “The outbound capacity of the Mengdong region has increased, but due to the small increase in the external power transmission, the utilization hours of thermal power units have decreased.” He said that due to the lack of provincial power resources allocation methods, the lack of inter-provincial interests to ease, Mengdong's foreign transmission channel transmission capacity only played less than 60%.

Moreover, as a region with extremely abundant wind power resources, the installed capacity of wind power in Inner Mongolia has grown rapidly. Director of new energy and renewable energy development at the Inner Mongolia Bureau of Liu Dongsheng said that Inner Mongolia alone in situ digestion, wind power development is very limited. Therefore, the scale and progress of long-distance transmission and integration into large power grids determine the speed of development of wind power in Inner Mongolia.

Multi-game circuit difficult to start

For the phenomenon that Inner Mongolian Wowo did not receive approval for the construction of an exit channel, Yang Lan, deputy general manager of Inner Mongolia Electric Power, felt "perplexed and anxious".

He introduced that the power transmission channel in the Mengxi area was connected to the North China power grid, but the operation of the northern channel was not stable since it was put into operation, affecting the transmission of power from the west of Monxi. Yang Lan said that in April, Inner Mongolia Electric Power had communicated with the North China Power Grid and demanded that it compensate for the losses caused by Inner Mongolia Electric Power. In addition, the North China Power Grid shoulders the heating task and has limited the acceptance of Mengxi Power.

Yang Lan said that in 2007, the third power transmission EHV line of Inner Mongolia Electric Power Co., Ltd. had already passed the demonstration. After coordination between the State Grid and North China Power Grid, the channel was changed from ultra high voltage to UHV, and guaranteed during the “Eleventh Five-Year Plan” period. Work started, but the project has been delayed until now has not been approved by the state.

Inner Mongolia Electric Power Company is currently responsible for the Mengxi Power Grid, which is different from the Mengdong Power Grid and does not belong to the State Grid. The failure to start the project on schedule was attributed to the fact that the State Grid intended to control the Inner Mongolian grid that was independent of its own system. Zhang Fusheng also stated that the State Grid intends to merge with the West Inner Mongolia grid.

As the national grid delayed its performance

The commitment of Inner Mongolia Electric Power, Inner Mongolia Electric Power is also planning to go north to Mongolia, South China Southern Power Grid's outbound channel. Yang Hao said that Inner Mongolia Electric Power intends to build a ± 800 kV UHVDC transmission line as a power transmission channel in Inner Mongolia. “We, as the northern provinces, transmit electricity to the South China Power Grid, and we must pass through the provinces of the central region. We will certainly encounter difficulties and need national coordination,” Yang Xi said. “But these difficulties are better than electricity shortages.”

In fact, the National Grid has planned to build the Mengxi high-voltage channel and report it to the National Development and Reform Commission. However, Inner Mongolia Electric Power believes that this scheme does not consider the grid connection between the UHV power grid and the Inner Mongolian power grid, and cannot solve the problems of wind power and thermal power generation in Inner Mongolia power grid.

For the construction of transmission channels, national decision-making bodies must weigh the game between multiple stakeholders. In the event that the electricity shortage is expected to increase, the balance is also tilting towards the origin of energy.

Inner Mongolia strives for new projects

While Inner Mongolia Electric Power is eagerly looking forward to building a power transmission channel as soon as possible, the Inner Mongolia Development and Reform Commission hopes to use this opportunity to obtain more energy projects, especially thermal power projects.

Zhao Gang said that despite the phenomenon of litter in Inner Mongolia, with the increase of electricity load in Inner Mongolia in recent years, the phenomenon of litter has gradually eased. It is expected that the power supply in the Mengxi region can be resolved next year, and that power shortages will occur in 2013 as in other regions.

According to Inner Mongolia Economic and Information Commission data, the installed surplus of power grids in the Mengxi region this year was approximately 3.4 million kilowatts, which was basically balanced in 2012, with a shortage of installed capacity of 900,000 kilowatts. In 2013, there was a shortage of installed capacity of 4 million kilowatts. Therefore, it is necessary to speed up the construction of new power projects to meet the electricity demand. It is hoped that in conjunction with urban heating, a batch of new cogeneration projects will be opened in the seats of the municipal governments of Hohhot, Baotou, Wuhai, Dongsheng District, etc., and an appropriate scale power grid will be built to support power projects.

At the same time, Inner Mongolia is also planning to promote the start of a new coal transportation channel. “We had been trying to build coal passages in the early years of the 11th Five-Year Plan, but we haven't been approved yet.” Zhao Gang said, “The coal transportation and the power transmission must be carried out simultaneously. The Mainland is lack of coal. How can we not transport coal? ?"

It is expected that this year's coal production in Inner Mongolia will reach 880 million tons, and by the end of the "Twelfth Five-Year Plan", it will exceed 1 billion tons. In fact, in recent years, the construction of Inner Mongolia Coal Coal Line has been continuously strengthened. In particular, after the large traffic jam on the Beijing-Tibet highway last year, a number of coal transportation lines were started to ease the strain on transportation capacity.
