3. The development pattern of Chinese power grid must concentrate on improvement of resources configuration optimization ability. The coal and hydro power mainly allocated in western and northwest China, but the energy resources and power consumption are mainly located in Eastern China and Central China where economy is relatively more developed. The distance between energy base and load center are normally km. The coal and hydro power mainly allocated in western and northwest China, but the energy resources and power consumption are mainly located in Eastern China and Central China where economy is relatively more developed. The distance between energy base and load center are normally km. These basic facts determine that China have to optimize nation wide allocation of energy resources, and realize large scale and long distance inter-regional transmission of power with compensated balancing between thermal power and hydro power in order to realize the effective exploration and efficient utilization of resources.

The existing power system based on 500kv is weak in interconnection, Interregional and inter-provincial power exchange capacity is not sufficient, resulted in unsatisfying the demand of resources, but also bringing negative impacts to the safe and stable operation of power grid and reliable power supply due to issues like long-term overloading of major connection lines and short currency over limit become more and more imminent. In order to effectively secure the power supply for future economic and social development, we must start construction of a strong network based on higher voltage level.

According to the plan, it is anticipated that around 2020, the UHV backbone network will be preliminarily completed. The ability and scale of power grid to optimize resources allocation will be greatly improved. This will greatly improve efficient exploration and utilization of Chinese energy resources. At that time, SGCC will form a power grid with interregional or even international transmission capacity over 250GW by UHV line. The operational stability and anti faults ability will also be greatly improved. According to the plan, it is anticipated that around 2020, the UHV backbone network will be preliminarily completed.
