Poor quality service. When ever there is a rain or storm power is cut. There are frequent disruptions in power supply, often there are whole day power cuts in the name of maintenance. There is no shortage of power in India now. Apartment complexes have the worst experience since they are big consumers of powers so supply to Apartments is low on priority. But they dont realise that these are people from whom they get maximum revenue along with commercial complexes which funds the the free supply/theft (T&D losses). I would suggest competition in this area, the monopoly should be abolished.

Very poor quality of supply, frequent power cuts. Constantly raising prices every year, no accountability
