In recent years, almost every time in March, central China will suffer from power shortages. This kind of seasonal power shortage is not due to lack of installed capacity, but electric coal is tight. It is understood that after the Spring Festival, the situation of coal supply in Hunan is extremely severe. The province's coal inventories fell at a rate of 28,000 tons per day. In the face of the severe power supply situation in Hunan Power Grid, Huazhong Power Grid Corporation applied to the Power Distribution and Communication Center of the State Grid Corporation of China for super-supply support from the Three Gorges Power Plant. At present, the daily limit of electricity in Hunan shows a gradual downward trend.

Current situation: Seasonal characteristics of the grid's abundance and abundance Since March, rainfall in Hunan Province and reservoirs have been significantly less, and hydropower stations have reached or approached dead water levels, and their ability to generate electricity is severely limited. Due to lack of power generation capacity, Hunan Province has implemented orderly electricity use measures on March 21.

In the face of the severe power supply situation in Hunan Power Grid, Huazhong Power Grid Company has used the favorable opportunity for the recent increase in water supply from the Three Gorges to apply for super-supply support from the Three Gorges Power Plant to the Power Distribution Communication Center of the State Grid Corporation of China. The National Training Center has arranged the Three Gorges to send 450,000 kilowatts of electricity to support Hunan. At the same time, Henan Province, Henan Province, Henan Province, Henan Province, Henan Province, has provided electricity for 300,000 kilowatts of electricity.

Seasonal power shortage in Hunan is not a case of Central China Power Grid. Central China Power Grid supports 396 million people in six provinces and cities in Hubei, Hunan, Henan, Jiangxi, Sichuan, and Chongqing, and is the nation's most populated regional power grid. With the rapid growth of electricity load in the entire network, the situation of power shortage in Central China is getting more and more serious. Despite the abundant hydropower resources, the seasonal characteristics of abundance in the Central China Power Grid are obvious.

Suggestions: To promote the transformation of energy transmission methods In recent years, it has become normal for the six provinces (cities) in Central China's network to lose electricity in the winter and spring. This has also become the topic of the NPC deputies of the Central China Power Grid Company when they participate in the two sessions of the country.

During the two sessions this year, the three National People's Congress representatives of Xi'an China Power Grid Corporation Xie Mingliang, Mao Rifeng, and Tang Wenquan focused on how to solve the problem of seasonal power shortage in central China, and actively provided advice and suggestions on the basis of UHV and strong smart grid construction and clean energy development. Proactively promoted the superiority and special role of UHV power grids to leaders at various levels and people's congress representatives, and led the organization to submit a report on “Accelerating UHV power grid construction to fundamentally solve the problem of electricity shortage in Hubei”, and jointly reported on the promotion of power grid construction. Legislative Proposals "Recommendations on Increasing the Proportion of Three Gorges Power Distribution in Central China" "Proposal on Further Promoting Generation Power Transaction to Promote Energy Saving and Emission Reduction of Electric Power" "Proposal on Establishing National Standards for Environmental Impact of Transmission and Transformation Projects as Quickly as Possible" "About Strengthening Energy Industry Planning Recommendations and other five recommendations.

"In the past few years, with the development of UHV and the rapid development of the power grid, the ability to optimize the allocation of electric power resources has become increasingly strong at the level of the State Grid Corporation of China." Xie Ming, deputy chairman of the National People's Congress and chairman of the Central China Power Grid Corporation and party secretary He said during the two sessions of the National Conference this year.

Countermeasures: Inter-provincial and inter-provincial power generation rights trading In 2010, the Hubei Provincial Government and the Inner Mongolia Autonomous Region Government signed a strategic economic and social cooperation agreement, stipulating that “starting from 2010, we will increase the power transmission from Inner Mongolia to Hubei and reach 20 billion kilowatt-hours by 2015. ". According to reports, the large-scale energy base in Inner Mongolia is 600 to 1,500 kilometers away from the eastern load center, which is an economically reasonable distance for UHV transmission.

At the end of 2010, China’s total installed capacity of power generation reached 962 million kilowatts, of which thermal power installed capacity accounted for approximately 76%, and non-fossil energy installed capacity accounted for only 24%. Thermal power consumes roughly 50% of coal resources, and carbon dioxide emissions also account for about 50%. The power industry has become an important area of ​​energy conservation and emission reduction.

Mao Rifeng, general manager of Central China Power Grid Corporation, stated that power generation rights trading guided by energy saving and emission reduction targets should be vigorously promoted; corresponding transmission pricing policies should be formulated as soon as possible; investment in power grid construction should be increased to accelerate the construction of UHV power grids and generate electricity for trans-provincial inter-provincial power generation. The transfer of power provides strong network support and promotes the implementation of power generation rights trading nationwide.

The implementation of power generation rights trading is an effective way to innovate mechanisms, reduce costs, and implement connotative energy saving and emission reduction. Generation rights trading can guide large-capacity, high-parameter, high-efficiency, low-emission generators to replace small thermal power generation, improve energy conversion efficiency, reduce carbon dioxide and sulfur dioxide emissions, and reduce environmental pollution. The development of trans-regional and inter-provincial power generation rights trading will help expand the scale of power generation transactions, increase energy-saving emission reduction efforts, help to achieve a more optimal allocation of resources, but also help improve the economic efficiency of power generation companies.

Interview: Implementing mandatory quotas for renewable energy combined with the operation of China's electricity market, Mao Jifeng, general manager of Huazhong Power Grid Corporation, proposed to impose a mandatory legal requirement on the share of renewable energy in total electricity consumption. Implement compulsory quotas.

Liang Liang: How to solve the reasonable allocation of the share of renewable energy in the total electricity consumption?

Mao Rifeng: You can choose a demonstration area as a pilot to implement renewable energy demand quotas. The regional renewable energy demand quota is also the demand quota for each province (city) in the region. Under the constraints of demand quotas, provinces (cities) with insufficient renewable energy resources will actively participate in cross-regional and inter-provincial transactions to achieve their goals, and prioritize the allocation of renewable energy power demand quotas into the province's (city) power balance so as to ensure the power grid The company has purchased the demand market for renewable energy in full, and has increased the enthusiasm and initiative of grid companies to purchase renewable energy.

Liang Liang: What are the specific measures?

Mao Rifeng: Implementing a nationwide renewable electricity demand quota. First, determine the national quota target for renewable energy power, and then allocate the country’s overall target to the region or province (city) according to the principle of fairness and reasonableness. Develop renewable energy power certificate trading. Set up a special management agency to issue green certificates. Renewable energy power certificate trading can be conducted first among power grid companies. After successful experience, renewable energy power certificate trading can be carried out in a wider range. The main body of trading can no longer be limited to power grid companies. Other companies can also reflect the environmental value and social value of renewable energy power through renewable energy power certificate trading.
