SBC-Hindupur is really active and most parts of it are under the wires, poles are erected in almost 90% of the whole SBC-GY stretch, wiring done in most places between DMM-GY too..Not too active in PKD-DMM via SSPN though, the last i went..

We can expect this to be complete by 2014 end or so being very optimistic that is,else could go even beyond that..
