The state govt does not try to produce more electricity calculatingly up to the level of need .The sources of wind ,water,sunlight and lignite should be fully used for the production.Atomic power is contradictory one .Kudankulam is a central govt project .We don't know how much it would help to Tamil nadu.
The state govt is purchasing electricity from private companies for higher cost.So it may want to continue purchase from others than producing.;it may from their benamis or party men or for indirect commission.
The Central govt gave continuous pressure to bifurcate the Tamil Nadu Electricity board in three companies .For some period it rejected but now it has divided in three as the first step of privatisation .The policy of central and state govts is to privatise all govt institutions so that they get gain from that companies .
Once Kolkutta was called a dark city and now it is heard that it supplies its excess electricity to other states.That state had long term and short term goals in production of electricity and using every small chance to produce electricity though the central govt is helpful .Tamil nadu also should follow this path.
