This is a list of states and territories of India by installed capacity of power utilities with electricity generation mode break-up as of 30-06-2012 and 31-01-2013 with figures in millions of watts (Megawatts). We cannot sustain the improvement in the quality of power supply unless tariffs are revised. Delhi's distribution companies lose Rs 1.79-1.93 per unit of power supplied to consumers. Planning Commission calculations of the financial performance of distribution companies in 20 major states (excluding Delhi and Orissa) shows that the average loss per unit supplied to the consumer was 90 paise in 2009-10. Key implementation challenges for India's electricity sector include new project management and execution, ensuring availability of fuel quantities and qualities, lack of initiative to develop large coal and natural gas resources present in India, land acquisition, environmental clearances at state and central government level, and training of skilled manpower to prevent talent shortages for operating latest technology plants.
