Hydro-power and coal based thermal power have been the main sources of generating electricity in the Indian power sector which has registered significant progress since 1950 when the process of planned development of the economy began. Nuclear power development has been at a slower pace, since its inception in the late sixties. In spite of the overall development in the recent times, the power supply industry has been under constant pressure to bridge the gap between supply and demand.
The Indian Power Sector has always received adequate priority since the process of planned development began in 1950. It has been getting 18-20% of the total Public Sector outlay in initial plan periods.

Structure of power supply industry
In December 1950 about 63% of the installed capacity in the Utilities was in the private sector and about 37% was in the public sector.
The Electricity (Supply) Act, 1948, proposed creation of State Electricity Boards (SEBs) for
