Information about the cold winter in Beijing in 2004

I hope you can use it.

"Although the supply of natural gas in Beijing is relatively tight this year, through the adjustment measures such as starting the heating emergency plan, the gas consumption for the Spring Festival heating and the new heating season this year has been guaranteed." On the morning of 26th, at the second press conference, Chen, director of Beijing Municipal Administration Committee, said affirmatively when asked by our reporter.

The "cold winter" has increased Beijing's natural gas consumption.

Chen explained to the media that this winter is different from previous years. The cold season in previous years all appeared in the middle and late June of 1, and in 2004 it began to enter the cold season on February 20th of 16, which was about 4 degrees lower than the average temperature in previous years, making it the coldest winter since 16. Such weather conditions have increased Beijing's natural gas consumption.

According to Chen, the daily gas consumption in Beijing has increased from the initial180,000 cubic meters to 2 10/0,000 cubic meters, and then to 23 million cubic meters, and sometimes even to 24 million cubic meters.

In addition to the weather, Chen said that the rapid development of urban construction and industry in Beijing in the past two years is also an important reason for the increase in natural gas consumption. The rapid development of urban construction and industry has brought great vitality to Beijing's economy, but it has also brought great pressure on gas consumption.

In 2005, the gap between energy supply and demand remained huge.

In fact, it's not just natural gas that worries Beijing leaders. In 2005, the gap between energy supply and demand in Beijing was still huge.

According to the interpretation of Beijing's national economic and social development plan in 2005 provided by the Municipal Development and Reform Commission, the total electricity consumption in Beijing in 2005 is expected to reach 48.298 billion kWh, up 6.46% year-on-year. The estimated coal consumption is not less than 28 million tons; The demand for refined oil is expected to reach 4.2 million tons; It is estimated that the consumption of natural gas will exceed 3 billion cubic meters.

According to the interpretation of the plan, the supply of thermal coal in Beijing has been running below the warning inventory for a long time, and the inventory of individual enterprises is only enough 1 day. Beijing is not only extremely short of primary energy, but also relatively short of secondary energy production capacity. 70% of electricity, 94% of coal, 1.000% of natural gas, 1.000% of oil and 60% of refined oil all need to be imported from outside. The tight railway transportation capacity also brings great pressure to energy supply and storage. To solve the energy problem for a long time, it is necessary to shift from emergency regulation to system regulation.

Countermeasures

Beijing plans to open Russian natural gas sources this year.

The second gas source can supply 2 billion cubic meters of natural gas every year in the future.

A few days ago, I learned from Beijing's long-term natural gas development plan that Beijing plans to open up a second gas source from Russia.

According to the plan, Beijing's natural gas consumption will reach 4 billion cubic meters in 2005, 5 billion cubic meters in 2007 and 6 billion cubic meters in 20 10.

According to the plan, the distribution of natural gas sources is initially considered as: 4 billion to 5 billion cubic meters of natural gas per year (including second-line gas transmission capacity) and the second gas source (Russian natural gas or LNG, etc.). ) 2 billion cubic meters per year. Due to the large seasonal peak-valley difference of gas consumption in Beijing, the seasonal peak gas consumption is generally 3-4 times of the annual average gas consumption, so it is necessary to build a certain scale peak-shaving gas source or build an underground gas storage with a total effective volume of more than 65.438+0.2 billion cubic meters.

According to this plan, when the demand for natural gas is 4 billion cubic meters in 2005, the maximum daily gas supply will reach 32 million cubic meters; The daily gas supply capacity of the second line of Shaanxi-Gansu-Ningxia natural gas to Beijing reaches 7 million cubic meters, and the daily gas supply capacity of the second gas source (Russian natural gas or liquefied natural gas, etc.). ) and supporting gas storage is 6,543,806,000 cubic meters, and the daily gas supply capacity of North China Oilfield is still 800,000 cubic meters.

The government should develop new energy sources.

NPC representatives suggested reducing dependence on traditional energy sources.

In response to the serious energy shortage faced by Beijing, on the 26th, deputies to the National People's Congress suggested vigorously developing new energy sources such as solar energy, sewage utilization (its temperature energy) and geothermal energy to replace conventional energy sources such as coal and natural gas. It is suggested that the Municipal Development and Reform Commission establish a project, give financial subsidies to the experimental section and establish a demonstration project.

Deputy Fu believes that Beijing has advantages in developing new energy sources. First, coal-fired boilers are still being rebuilt. Second, a large number of public buildings provide a wide range of places. Thirdly, there have been many successful demonstration projects that use solar energy, geothermal energy and hydropower to provide heating systems.

He suggested actively promoting clean new energy sources such as hotels and restaurants such as solar energy, ground source heat pump and water source heat pump. In order to avoid future troubles, geological departments should make unified planning in advance and draw areas suitable for water source heat pumps and ground source heat pumps according to geological conditions. Professional departments and relevant departments should formulate specifications and unify engineering standards to ensure long-term use.

Carry out the citizens' energy-saving campaign.

Environmentalists hope to take the "gas shortage" as an opportunity to strengthen environmental awareness.

On the evening of 26th, Liao Xiaoyi, a non-governmental environmentalist and director of Beijing Global Village Environmental and Cultural Center, said in an interview with this reporter that Beijing should take this "gas shortage" as an opportunity to carry out energy-saving campaigns, strengthen the environmental awareness of all sectors of society, start with the government and adopt energy demand side management.

Liao Xiaoyi has just returned from Sichuan. She said that in the small town where she went, there was no electricity for half a day every week. By contrast, Beijing is much luckier. In fact, Beijing has great energy-saving potential, and there is great potential for both air conditioning in summer and heating in winter.

According to the survey of "26-degree air conditioning energy saving" initiated by six non-governmental environmental protection organizations such as Beijing Global Village last year, the electricity consumption of civil air conditioning accounts for 40% of the total electricity consumption in Beijing in summer. Although the energy consumption of air conditioners in winter has not been measured, Liao Xiaoyi thinks that this is not a small amount.

Liao Xiaoyi believes that Beijing's winter heating can be managed from the demand side. She introduced that in the second half of last year, Beijing Global Village and the Olympic Organizing Committee jointly held an energy-saving publicity campaign of "Turn down the air conditioner once in winter", which was attended by more than 80 Olympic contracted hotels, and the energy-saving effect was very obvious. A hotel saves 1000 kwh a day.

Liao Xiaoyi suggested that the government launch a citizen movement with the theme of energy conservation.

A single heat source is prone to problems.

The general manager of China Petroleum and Natural Gas Group said that Beijing's failure to contact the company was one of the reasons for the "gas shortage".

"A single heat source can easily lead to safety problems," said Tian Jinfeng, manager of the sales branch of Beijing Thermal Power Group. He believes that Beijing has no choice but to start an emergency plan for gas supply and heating in winter.

Chen Geng, general manager of PetroChina, also said in an interview with the media that many industrial boilers in Beijing have changed from burning coal to burning natural gas, but the connection with PetroChina is not good. Judging from the relationship between supply and demand of natural gas in China, natural gas is limited after all. It is not allowed to convert all industrial and civil facilities burning coal from output and resources to natural gas.

Wu of Beijing Gas Group said that due to the development of a large number of heating loads, natural gas has now accounted for a considerable proportion of the annual gas consumption, even exceeding 80% at the peak in winter.

Energy experts believe that the government wants to use clean energy from the perspective of environmental protection, but burning coal for heating does not mean that it will definitely pollute the air. As long as it meets the national emission standards, the fuel mode should not be restricted.
