Strengthening Technical Renovation of Power Grid, and Fully Tapping the
Potential of Resource Allocation in the Existing Power Grid
SGCC continuously carries out projects to enhance transmission capacity in the existing power grid. The first
phase of projects has increased transmission capacity by 19,700 MW, and the second phase has increased the
transmission capacity by 51,600 MW while the on-going third phase has increased the capacity by 13,910 MW.
The total incremental transmission capacity is 85,270 MW.
The planning investment of technical refurbishment of power grid is RMB 102.2 billion Yuan according to the
11th Five-year Plan of SGCC, including the cost of refurbishment projects of rebuilding and enlarging with
177,900 km of transmission lines and 345,000 MVA transformation capacity. The refurbishment of the existing
power grid has greatly enhanced the stability of power grid, re-powered the equipments status standard, enlarged
the transmission capacity, reduced the loss of power grid and built a conservation-oriented and environmentfriendly
power grid.
