 With the dramatic increase of the national electricity consumption, the maximum load surge in the national power grid construction in the "12th Five-Year" period, the 14 DC projects to ease the electricity pressure, to protect the safe operation of the power supply and grid.
2011, the national electricity consumption increased dramatically. Growth situation from the point of view, to 2015, electricity consumption of 6.3 trillion kwh, the maximum load will reach 1.01 billion kilowatts, "12" average annual growth rate of 8.6% and 8.9%, respectively; 2020, the society as a whole electricity 8.3 trillion kwh, "Thirteen" during the 5.6 percent average annual growth rate of electricity consumption; 2030, total electricity consumption 10.4 trillion kwh, a maximum load of 1.73 billion kilowatts ,2020-2030 average annual growth 2.3% and 2.7%.

State Grid Corporation of Development Planning Division Lu Jian, deputy director of the expected 2015 total electricity consumption will reach 6.3 trillion kwh, the maximum load is approaching 1.01 billion kilowatts, the average annual growth rate of the "12th Five-Year" period were 8.6% and 8.9 %. The power of rapid growth requires the support of the UHV network construction, he suggested that authorities should speed up the approval of the progress of the Huainan - Shanghai "," Hami - Zhengzhou "UHV.

The national grid, "the 12th Five-Year" period wishes to vote to build 14 dc Project. The national network is expected to meet the demand for electricity, "the 12th Five-Year" period will be voted to build Jinping - the South, Golmud - Lhasa, Xiluodu - western Zhejiang, Huaidong - Chengdu 14 ultra-high DC project. "12" exchange works form a ring of three vertical and three horizontal grid, built Ximeng - Nanjing, Zhang North - Nanchang, Mengxi - Changsha, Northern - Weifang, Jingbian - Lianyungang, Ya'an - Shanghai exchange programs. Thirteen Five-Year Plan, the vote will be built 15 DC Project.

Some authorities have confirmed that approved by the Huainan - Shanghai UHV exchange program of the countdown. According to the network planning of the country, built in 2012 Ximeng - Nanjing East Rift UHV, built in 2013 Xiluodu - western Zhejiang DC, built Yaan - Anhui Southern Cross-Island UHV. It is understood that UHV backbone network "three vertical and three horizontal ring, no one in construction. Electricity consumption in 2015 or super 6 trillion kwh. Forecast data from the State Grid, the next 20 years, China's demand for electricity continued to grow, additional capacity will reach 6.2 trillion kwh, the new load will reach 1.07 billion kilowatts. State Grid is expected that the national installed capacity will reach 1.47 billion kilowatts in 2015, average annual increase of 8.9% during the "12", "Thirteen" average annual increase of 4.6% in 2030 will reach 2.47 billion kilowatts.
