Introduction
Power generated far away from load due to
source of energy (hydro, coal mines etc) Require high voltage transmission lines (grid)
to transfer large power from generation pointsto load centers
Need to appropriately plan the grid system Various generation size
Changing load demand Long lead time for transmission projects
