The reporter from Seedao.com was informed that on June 15, 2022, the Chongqing Municipal People's Government issued the "14th Five-Year Plan for Energy Development", pointing out that the "14th Five-Year Plan" period is the first five-year period for China to promote peak carbon dioxide emissions and carbon neutrality. In 2019, the low-carbon energy transition has entered a critical period of peak carbon dioxide emissions, and Chongqing's energy structure adjustment will face greater challenges.

Development Goal: Remarkable achievements in energy green transformation

The "Plan" targets that by 2025, the coal supply guarantee capacity will reach 50 million tons; the installed power capacity will reach 36.5 million kilowatts, and the electricity consumption of the whole society will reach 162 billion kilowatt hours; the output of conventional natural gas and shale gas will reach 5 billion cubic meters respectively. , 13.5 billion cubic meters; the supply capacity of refined oil reached 10.5 million tons.

The green transformation of energy has achieved remarkable results. By 2025, the total responsibility weight of renewable energy power consumption will reach the target set by the state, and the proportion of non-fossil energy consumption will increase to 25%; the proportion of coal consumption will be reduced to 40%, the proportion of oil consumption will remain at 15%, and the proportion of natural gas consumption will reach 20%.

Energy efficiency has been greatly improved. The reduction index of energy consumption per unit of GDP meets the national requirements; the average coal consumption of thermal power supply is controlled below 300 grams of standard coal/kWh, and the comprehensive line loss rate of the power grid is controlled below 4.8%; the multi-integration and high-flexibility power grid is built, and the reliability rate of power supply of the distribution network is Above 99.893%.

 By 2025, the transformation of power supply facilities in old residential areas will be completed, and the "one meter for one household" will be fully covered, and the per capita domestic electricity consumption of residents will reach more than 900 kWh.

Build a multi-safety energy supply system

The "Planning" proposes that by 2025, the city's comprehensive energy production capacity will reach more than 34 million tons of standard coal. How to achieve? Chongqing will build an energy supply "safety net" from the aspects of coal, electricity, oil and gas supply guarantee, Wanshan energy infrastructure network, and improving the safety level of energy operation.

In terms of strengthening the guarantee of power supply, we will promote the construction of the Sichuan-Chongqing UHV main grid, and complete the Hami-Chongqing ±800kV UHV DC transmission project and the Sichuan Tianfu South to Tongliang 1000kV UHV AC power transmission and transformation project. The external power transmission capacity will reach 15 million to 19 million kilowatts.

In terms of improving the energy infrastructure network, the interconnection between the local power grid and the national power grid will be strengthened to achieve balanced power supply in each supply area, reasonable distribution of power flow, and stable and reliable power quality. At the same time, relying on ports, railway stations and user freight yards, a number of coal storage bases will be built, renovated and expanded in due course, and strive to achieve a coal storage capacity of over 7.5 million tons per year in Chongqing. Build a comprehensive natural gas peak shaving system with underground gas storage as the mainstay, gas field peak shaving, CNG and LNG storage stations as supplements, and can be supplemented by interrupted users. Strive to reach 3.86 billion cubic meters of gas storage and peak regulation capacity in Chongqing by 2025.

Improve the energy infrastructure of urban residents, improve the power supply capacity of 110kV and 10kV urban distribution networks, and promote the coordinated and orderly development of diversified loads such as new energy, distributed energy, and electric vehicle charging and swapping facilities with the distribution network.

Promote green and low-carbon transformation of energy structure

In the next five years, a new round of scientific and technological revolution and industrial transformation will promote the comprehensive upgrading of the energy industry. The "Plan" proposes to implement the carbon neutralization action in the energy field, and promote the green and low-carbon transformation of energy production and consumption in a scientific and orderly manner. Implement renewable energy alternatives to reduce fossil energy consumption.

First of all, it is necessary to reduce the proportion of coal in the energy supply and consumption structure, and continue to increase the proportion of clean energy supply, such as improving the efficiency of wind power generation, orderly promoting the construction of rooftop photovoltaics in the whole county, and promoting biomass power generation according to local conditions. Strictly control coal consumption in the steel, chemical, cement and other coal-using industries, and promote the "coal-to-electricity" and "coal-to-gas" projects in an orderly manner. Reduce carbon emissions from the energy industry, strengthen carbon emission reduction in fossil energy development and production, and promote energy processing, storage and transportation to improve efficiency and reduce carbon emissions. Promote the integrated development of natural gas, solar energy, geothermal sources, water sources and other renewable energy sources. Accelerate the construction of "oil, gas, electricity and hydrogen" comprehensive energy stations, improve the network layout of LNG filling stations, increase the filling function of LNG filling stations, and form a network system of LNG filling stations covering Chongqing.

Second, promote the adjustment of energy consumption structure in key industries. Optimize industrial layout and strengthen energy conservation in key areas such as industry, construction, transportation, new infrastructure, and public institutions. Implement key energy-saving projects, take energy efficiency improvement in key industries as the starting point, and build a green manufacturing system covering the entire industrial chain and the entire life cycle of products.

Strengthening energy cooperation in the Chengdu-Chongqing economic circle

The "Plan" mentioned that it is necessary to actively implement the national regional development strategy, actively integrate into the domestic and international dual cycle, and strengthen the connection of energy resources.

In terms of Sichuan-Chongqing cooperation, give full play to the complementary characteristics of power supply and demand and power supply structure between Sichuan and Chongqing, guide the power market players of the two provinces and cities to strengthen medium- and long-term power cooperation, and promote the integration of Sichuan-Chongqing power grids. Explore the establishment of a work integration mechanism for power trading institutions in Sichuan and Chongqing, jointly cultivate and develop the power spot market and the Sichuan-Chongqing integrated power auxiliary service market, and promote market-oriented power transactions.

Taking advantage of the rich natural gas resources, active consumption, flexible pipeline network scheduling, wide market connectivity and strong price conductivity in Sichuan and Chongqing regions, the Chongqing Petroleum and Natural Gas Trading Center will be used as a platform to build a national natural gas central market.

Strengthen cross-regional cooperation in coal, and promote the establishment of coal reserve bases in major coal consumption areas and key nodes of transportation channels in the Sichuan-Chongqing region. Establish a monitoring information sharing mechanism for the refined oil market in the Sichuan-Chongqing region to enhance market monitoring and emergency response capabilities.

Accelerate the construction of the Chengdu-Chongqing Hydrogen Corridor, strive for the implementation of the fuel cell vehicle demonstration city cluster policy in the Chengdu-Chongqing area, and promote the development of the hydrogen energy industry in the industrial-leading cities led by the main urban area of Chongqing and the Chengdu metropolitan area, and help the corridor between Chengdu and Chongqing. The layout of the hydrogen energy industry in the city. Editor / Xu Shengpeng
