National Grid held an annual working meeting on January 5, 2012, announcing that the power grid investment in 2011 reached 301.9 billion yuan, an increase of 13.7% year-on-year, an increase of 18% over the same period of last year, and proposed that the planned grid investment in 2012 was 309.7 billion yuan, a year-on-year increase of 2.58%.
In 2011, the State Grid planned to complete a grid investment of 292.5 billion yuan, but actually completed 301.9 billion yuan, an increase of 9.4 billion yuan. China's energy distribution and energy consumption do not match. It is an optimal choice to build power supplies in the western and northern regions where energy resources are abundant, and then send power to load centers. However, China’s existing power grids are mainly based on 500-kV EHV lines, which not only have low power transmission capacity, but also cannot realize long-distance transmission.
State Grid predicts that in 2015, the entire society will use 6.3 trillion KWh of electricity and the maximum load will reach 1.01 billion KW. The average annual growth rate during the "12th Five-Year Plan" period will be 8.6% and 8.9%, respectively. UHV grid support.
In 2012, the State Grid will focus on promoting the UHV preparatory work to ensure that “Six Cross and Three Straights†are approved by the State and started: Ximeng to Nanjing, Huainan to Shanghai, Mengxi to Changsha, Ya'an to Weinan UHV AC project, Haminan To UHV DC projects in Zhengzhou, Xiluodu to West Zhejiang, and Hamixi to Chongqing; and to strive for an UHV AC project from North Zhejiang to Fuzhou, and two UHV DC projects from Zhudong to Sichuan and Ximen to Taizhou were obtained during the year. Approved.
