Development of National Grid National Grid planned in a phased manner Phase-I envisaged Interconnection of Regional Grids through HVDC Back-to-Back links having cumulative capacity of 5000 MW has been completed in 2002 Present inter regional capacity is 9500 MW It is envisaged to have 37,000 MW inter regional capacity by 2012 comprising of high capacity HVDC and HVAC lines (both 765kV and 400kV) and 50,000MW by 2016
Technology Integration To conserve the Right-of-Way while meeting the power transfer requirement of immediate as well as long-term Technology adopted for progressive enhancement of transmission capacity of same Tr. corridor through High capacity 400kV (quad) lines 800kV EHVAC line initially operated at 400kV High capacity 800kV HVDC systems initially operated at 600kV Series compensation and TCSC High temperature endurance conductor like INVAR Multi-ckt. line and compact towers (ROW for 800kV line 85 m to 64 m) Optimal utilisation of existing infrastructure through Series Compensation Uprating/Upgrading of lines Enhancement of thermal capacity of line (75-85 0 /95 0 C)
