It is learned from the State Grid Corporation of China that is being held at the 2012 mid-year meeting that in the first half of the year, the company accelerated the construction of UHV projects, optimized the grid structure, and greatly improved the ability of cross-regional and cross-provincial transmission and grid optimization of resource allocation. The absorption capacity is significantly enhanced.
In the first half of the year, the State Grid Corporation’s operating areas added 5.76 million kilowatts of wind power and photovoltaic power grid-connected capacity and 100,000 kilowatts, up 29.7% and 4.7% year-on-year; consumption of new energy 47 billion kilowatt-hours, an increase of 22.4% year-on-year. Since the "Eleventh Five-Year Plan", a total of 210 billion kWh of new energy has been consumed, 69.3 million tons of standard coal has been saved, and 173 million tons of carbon dioxide reduced.
In response to the early water inflow and large water volume in Central China, the State Grid Corporation of China played the role of UHV and other cross-regional and cross-provincial projects in optimizing the allocation of resources on a large scale, consuming 5.62 billion kWh of hydropower, an increase of 26.8% year-on-year. In the first half of the year, UHV AC and DC projects achieved a total of 10.4 billion kWh of cross-regional power transmission, a year-on-year increase of 57%. Ensure the safe and stable operation of the power grid and reliable power supply.
According to reports, since the beginning of this year, in the face of the severe economic situation, complex external environment, and arduous reform and development tasks, State Grid Corporation of China has conscientiously implemented the decisions and deployments of the Party Central Committee and the State Council, accelerated the development of power grids, innovated systems and mechanisms, and vigorously promoted various tasks. , Maintaining a good situation of stable and healthy development overall.
In the first half of the year, the State Grid Corporation completed a fixed asset investment of 124.38 billion yuan, of which 119.26 billion was invested in the power grid. The 110 (66) kV and above AC line started 27,201 kilometers and put into production 25,597 kilometers. The amount of electricity traded in the national power market was 225.9 billion kWh, a year-on-year increase of 10.1%. It has been rated as an A-level enterprise in performance appraisal by the SASAC for 8 consecutive years, and maintained the 7th place in the 2012 World Top 500 Enterprise Ranking.
At the same time, State Grid is actively serving the western development strategy and the leap-forward development of Xinjiang, accelerating the power transmission from Xinjiang, the Hami South-Zhengzhou UHV DC project, and the construction of the 750 kV second channel connecting Xinjiang and Northwest China, Jinping- The bipolar low-end of the Sunan UHV DC project was put into trial operation, and my country's first double-circuit UHV AC power transmission project from Anhui to East on the same tower progressed smoothly. The key post-disaster reconstruction project in Yushu, Qinghai-Yushu Power Grid and Qinghai Main Power Grid Interconnection Project started construction. The "Electricity Skyway"-the Qinghai-Tibet AC/DC interconnection project was put into operation. A total of 445 million kilowatt-hours of electricity were sent to Tibet, accounting for 29.6% of the electricity consumption of the central Tibet power grid. Power protection.
The construction of the provincial power grid has been further strengthened, the structure and layout of the 500 (330) kV grid have been optimized, and the power supply capacity and reliability have been significantly improved. Demonstration projects for urban power grid construction and transformation are accelerated. The transformation and upgrading of rural power grids and power construction in areas with no electricity were accelerated. In the first half of the year, 23.22 billion yuan was invested in rural power grids, the low voltage problem of 1.467 million households was solved, the power supply problem of 8,900 households without electricity was solved, and the power supply capacity and quality were improved.
The company has formulated an action plan for the comprehensive construction of smart grids, clarifying the construction goals and key tasks, and the development of key technologies and key equipment for the new generation of smart substations has been fully launched. Promote the application of smart meters. In the first half of the year, 20.3 million were added, reaching 92.65 million in total. The automatic collection of electricity consumption information of 97.69 million households was realized. New progress was made in the construction of intelligent charging and replacement service network for electric vehicles, integrating charging, replacement, logistics, Beijing Gaoantun Electric Vehicle Charging and Swap Station, which integrates monitoring and other functions, has been put into operation. A total of 243 charging and swapping stations and 13,283 charging piles have been put into operation.
