EVOLUTION OF POWER SYSTEM IN INDIA
PRE INDEPENDENCE - SMALL ISOLATED SYSTEM
PRIOR TO 60s - GENEARTION/TRANSMISION BY SEBS
DURING 60s - LIMITED INTERCONNECTION BETWEEN NEIGHBOURING STATES
70s - EMERGENCE OF CENTRAL SECTOR GENERATION ( NTPC/NHPC/NUCLEAR ETC.)

LATE 80s – INTEGRATED GRID OPERATION THRO’ 400kV SYSTEMLATE 90s - ASYNCHRONOUS INTER REGIONAL LINKS LONG DISTANCE HVDC LINKS / BtB STATIONS
