If Koodankulam power production starts then there will be solution to power cuts. But my mind says they won't start this power plant very soon. Power cuts occurs only at poor mans home. All the politicians were rich enough and they have generators / inverter in their home. Who cares about poor in this 20th century. Suppose if all the politicians suffer from this power cut they may take some steps.
Instead of constructing solar power plant, TN can reduce the solar panel cost which can be used by all peoples in Tamilnadu.
