With the "power" in 13th Five-Year "plan" officially released, the path of development in the next few years China power industry was clearly outlined, as the central rate of the two network, five large and four small electric power enterprises, the central government will undoubtedly is the most direct executor, facing the economic development trend, new technology progress of change, and the ongoing environmental pressure, and how these enterprises development goals in the next few years? Please look at the electric power enterprises in 13th Five-Year detailed planning.
National Power Grid Corp
As the largest public utility in the world, the national grid has reached a new high in 2015. Therefore, under the background of the new economy, the construction of the transmission and distribution line has become an indispensable means of steady growth of the government. On the other hand, in order to avoid distributed + storage and power plant erosion area of the Eastern market, the national grid has always stressed environmental protection of the long-distance transmission of clean energy in western, to show that the public grid is irreplaceable, and has been accepted by the government, so in 13th Five-Year during the development of the national power grid construction is the main keywords ultra high voltage, and the consumption of clean energy.
1, overall planning: the existing North China, East China, East China, northeast, north-west and other AC synchronous grid, the interconnected integration into the East and west of the two power grid. Among them, the western power grid is formed by interconnected power grid with different resources in the west, and the East power grid is mainly the interconnection of the main electric power area in the East.
2 line construction: 13th Five-Year, the construction of UHV network will be mainly divided into three batches, which before 2016 started five pay eight straight, to meet the current new energy and hydropower East; 2018 started four pay two straight, to form the eastern and Western power grid; 2020 started three pay has been "to connect Xinjiang and Tibet's two largest energy base, while promoting the cross-border power grid project. By 2020, the East and central areas were 310 million kilowatts, of which 50% were clean energy.
3, the new energy consumption: before 2020, an annual increase of 25 million kilowatts of wind power, photovoltaic power generation 20 million kilowatts installed capacity of the grid and send facilities. By 2020, China business district grid renewable energy installed capacity reached 570 million kilowatts, the total installed 35%; annual consumption of clean electricity 2 trillion and 200 billion kwh; improve the non fossil energy in primary energy consumption to 15.5%;
4, the transformation of rural power network: 2020, 110-35 kV substation capacity construction reached 12.88 million KVA, line length of 823 thousand and 200 km; 10 thousand volt distribution capacity reached 6.46 million KVA, line length of 3 million 271 thousand and 800 km.
Power Grid Corp in the South
Is different from the national grid to large-scale investment in power grid construction, China Southern Power Grid to focus more on the reform, especially in the implementation of the electric power system reform, China Southern Power Grid proposed: open and non discriminatory investment according to the policy of power grid, power grid project, and vigorously promote the control operation of open and transparent information. At present, the business area of Guangdong, Yunnan, Guizhou province has become the model for the project of the electricity reform, the existing situation, South network have changed much on the leading role of the new electricity reform is not in 13th Five-Year.
1, power grid planning: the existing five provinces (District) synchronous grid will gradually form a moderate scale, clear structure, relatively independent of the 2 synchronous grid. It takes the Yunnan power grid as the main body to form the synchronous power grid, and the other 4 provinces (districts) form a synchronous grid.
2, line construction: the construction of 6-8 transmission channels to meet the power supply requirements of Guangdong and Guangxi in Yunnan, the southeast and the surrounding countries. We will steadily promote the construction of the cross provincial channels, such as two cycles in the northwest of Yunnan and the network of Hainan, and the capacity of 11 million kilowatts for the new power supply to the West. In 2020, the "eight - back exchange and eleven - back DC" transmission lines were built, with a power supply of 46 million KW.
3, agricultural network transformation: investment of 130 billion yuan, for rural power grid upgrading and upgrading.
4, energy saving and synergy: the potential of energy saving in the power grid is deep, and the overall line loss rate of the whole network is reduced to less than 6.5% in 2020.
5, new energy vehicles: by 2020, the infrastructure system to meet the needs of the development of 1 million electric vehicles is built.
China Huaneng Group
1, overall planning: by 2020, to enter the ranks of world - class enterprises with international competitiveness.
2, clean energy: we plan to produce low carbon and clean energy over 29 million 400 thousand kilowatts, so that the proportion of clean energy installed will reach 35%. We will carry out relevant research and demonstration of hydropower development in the lower reaches of Yarlung Zangbo River.
3, the coal and electricity industry: accelerate the transformation of ultra-low emissions, invest 30 billion yuan before 2020, complete the ultra-low emission transformation capacity of the unit to reach 104 million 200 thousand kilowatts, and the proportion of the unit reaches 94%.
4, international cooperation: by 2020, the capacity of power generation installed capacity is about 10%, and the proportion of international income is about 20%.
