Power grid investment rose the first break 500 billion, distribution network construction has become the focus of investment

2017-05-02 16:33:46 click: 772

In the national distribution network construction and transformation plan and a new round of rural power grids and other policies to guide the upgrade, accounting for 58% of the total investment in the grid 110 kV and below grid investment grew 35.6%. From the power investment trend, the degree of power grid saturation is still less than power, China's renewable energy consumption capacity and power supply reliability is still urgent need for continuous investment in power grid. With the slowdown in the growth of electricity consumption in the whole society, and most of the power supply and transmission line skeleton gradually improve the situation, the focus of China's power grid construction investment has been transferred from the backbone network to the distribution side.
Change: power grid investment rose the first break 500 billion
2016, China's power grid construction investment continues to increase, the speed continues to accelerate. Along the "second five" power grid development trajectory, power grid backbone network is increasingly strong, with the network, rural power supply level steadily improved, power grid service clean energy development capacity significantly enhanced.
State Energy Bureau released statistics show that in 2016, China's major power companies to complete the construction of electrical power construction investment 885.5 billion yuan. Among them, the investment in power construction completed 34.29 billion yuan, down 12.9%; power grid construction completed investment 542.6 billion yuan, an increase of 16.9%.
Reporters access to relevant statistics and found that the "second five" since the completion of power grid construction projects have different degrees of improvement every year. Among them, in 2011 completed 368.2 billion yuan, up by 67.7 percent; completed in 2006 369.3 billion yuan, up 0.2 percent; 2013 completed 389.4 billion yuan, up by 5.4 percent; 2014 breakthrough 400 billion yuan, reaching 411.8 billion yuan ; 2015 to complete 460.3 billion yuan, the growth rate for the first time to reach double digits; 2016 first break 500 billion yuan mark, reaching 54.26 billion yuan, growth rate rose to 16.9%.
The value of grid investment in the new transmission lines and substation equipment to be reflected.
In 2016 the national power grid new 220 kV and above transmission line length of 34,906 km, an increase of 5%; new 220 kV and above the capacity of 24.33 million KVA, up 11.1%. Both are maintaining high growth.
From the main network construction point of view, the ability to optimize the allocation of resources to further enhance the 2016 cross-regional, inter-provincial power transmission growth rate increased year on year. Cross-district power generation increased by 6.9%, compared with 2015 increased by 4.1 percentage points. China Electric Power Enterprise Association of experts pointed out that the increase in cross-district power transmission is mainly the grid companies actively through the UHV sent to the northwest of the new energy and southwest hydropower. Inter-provincial output power increased by 4.8%, 5.9 percentage points higher than 2015, China Southern Power Grid area power transmission capacity increased by 3.3%.
In 2016, the national grid to UHV as the representative of the power grid construction to speed up the "three cross six straight" UHV project to speed up the construction, completed and put into operation "three cross has been" UHV project. At the same time, the Northwest 750 kV main grid, Tibet and the network, Sichuan and Chongqing third channel and other voltage level key projects are also accelerating the construction. Over the past year, the State Grid Corporation inter-provincial inter-provincial transmission of southwest hydropower 107.4 billion kwh, an increase of 7.4%. The annual consumption of clean energy is 1189.3 billion kwh, up 15.2% year on year.
State Grid Corporation and China Southern Power Grid Corporation 2017 working conference data show that: over the past year, the State Grid Corporation to complete the power grid investment 497.7 billion yuan. Which a new round of rural power grids to upgrade investment 171.8 billion yuan, new energy and the total investment of more than 64 billion yuan transportation project. China Southern Power Grid Corporation in 2016 to complete fixed assets investment 102.2 billion yuan, an increase of 22.6%. Which completed the construction investment 85.3 billion yuan, seven key projects all put into operation on schedule.
Power grid construction efforts to increase, for the regional economic development has brought a scale, effective new investment, power equipment manufacturing enterprises performance has gone up. According to research data, power grid investment for each additional 100 million yuan, driving industry output 300 million yuan. In 2016, the national grid investment 54.26 billion yuan, a record high, directly to the output value of more than one trillion yuan.
Trend: distribution network construction has become the focus of investment
In the power system internal investment structure, China's power supply, power grid investment in different periods, investment is very different. Since the "second five" to the next 10 years or even longer, the investment focus has gradually shifted to the power grid intelligent and distribution network construction, more biased with the electricity side.
2016 grid investment in the contrarian, to achieve a record high growth rate of 16.9%, with a new round of rural power grids to upgrade nearly 100 billion yuan investment projects and accelerate the construction of the national distribution network transformation is not unrelated.
Over the past year, the State Grid Corporation of a new round of rural power grids to upgrade investment of 171.8 billion yuan to complete the transformation of 36,000 small towns power grids, 782,000 million wells through power, 22,000 natural villages and new transformation and power transformation tasks, Tough fight "stage goal. China Southern Power Grid Corporation completed the transformation of rural power grid to upgrade 32.4 billion yuan to complete the 216 poor rural power grid investment 21.2 billion yuan, to achieve 66 poor villages through power. Rural integrated voltage pass rate increased 1.02 percentage points year on year, the cumulative rural users average power failure time than the planned time 0.09 hours / household.
Backbone grid construction is still the most definite part of the grid investment in 2017. According to the national grid company planning, 2017 will be built air pollution control "four cross four straight" special high pressure engineering and Jiuquan - Hunan, Zha Lute - Qingzhou DC project, started construction of northern Shaanxi - Wuhan DC and a number of special high pressure engineering.
On the situation in 2016, the saturation of power grid construction is still less than power, power investment is weaker than the phenomenon of grid investment is expected to continue. Although the overall supply capacity of China's power system has been rich, but in the renewable energy consumption capacity, peaking capacity, power supply reliability and so on, there is still a need for continuous power grid construction investment.
"Southern Power Grid Development Plan" pointed out that will strengthen the urban and rural distribution network construction, promotion and construction of smart grid, by 2020 the urban distribution network automation coverage rate reached 80%. State Grid Corporation also proposed that in 2017 will accelerate the construction of the distribution network transformation. Construction of intelligent modern urban distribution network, improve the construction standards, equipment quality and automation level, so that the wire section selected once, corridor once in place, substation civil construction once completed, to avoid large demolition building.
With the new urbanization, the pace of modernization of agriculture, new energy, distributed power, electric vehicles, energy storage devices, the rapid development of terminal electricity load growth, change, diversification of the new trend, to speed up the upgrading of distribution network The task becomes more urgent. It is worth noting that, in the power grid construction investment, the main network investment is the core indicator of electricity consumption growth, with the slowdown in this indicator, coupled with the increasingly perfect backbone construction, power grid investment will continue to focus on distribution network Transfer.
