@intended, thanks for informative post. People tend to think all govt ventures are of shabby quality. I've a few friends who are engineers at KPTCL (Karnataka Power Transmission Company Ltd). It gives me goosebumps when I hear their experience about planning and building new sub-stations, high power lines etc. Minute details that go into these things are simply amazing. All I can say is GP's assumptions about PowerGrid being archaic is not correct.
