Given the importance of adequate power supply in the economic development of the country,augmenting the power generation base has emerged as one of the priorities for India in the recent past. More than one-third of the investment outlay on infrastructure in both the 10th and 11th Plan was allocated to the power sector alone. Further, to address the power deficit situation, 12th Plan envisages increasing investment on generation from Rs 4,79,620 crores in 11th Plan to an estimated Rs 6,38,600 crores. This is expected to raise the power generation capacity additions from nearly 52 GW in the 11th Plan to 75 GW in the 12th Plan.
