Energy Survey

If India grows at 8 to 9% per annum, it will need at least 4 to 5 times the energy it currently consumes by 2030-31.

India’s current total primary energy supply (TPES) per capita stands at 520 kgoe (kg of oil equivalent) as against a world average of 1,688 and China’s 1,090 and USA’s 7,853 kgoe.

Hydel power has a current installed capacity of 32,000 MW.

Coal:

Of the four major fuel sources, coal has the largest share of India’s energy requirement at about 55%.

With an estimated reserve of 248 bn tonnes and proven reserve of 92 bn tonnes, the supply is expected to last about 80 years.

70% of power being produced in the country is from coal. Coal production has gone to 400 mt currently. Only 30 to 32% of energy efficiency is achieved through the present coal based power generation. Gas based plants have an efficiency of 50%. The latest super critical technology for coal based power generation takes the energy efficiency up to 40%.

Oil:

The current oil reserves will last only about 22 years.

Currently there is a 70% dependency on imports and it is expected to go up to more than 90%.

Oil and gas account for about 38% of the primary energy consumption in the country.

India’s consumption of diesel, petroleum and aviation turbine fuel is about 52 mln tonnes in FY06.

Total number of vehicles in India was about 67 mln in 2002-03; with about 24 mln added in the three subsequent years.

Gas:

Current gas availability is about 90 MMSCMD, against an estimated requirement of around 150 MMSCMD (Million Metric Standard Cubic Meters per Day)

India’s current reserves are about 30 tcf (Trillion Cubic Feet), enough for only about 30 years.

Gas has currently a share of 11% in total installed capacity. The share of natural gas in the country’s energy basket is about 8%, but is still far lower than the average of 23% for the world.

Uranium:

India has a requirement of about 600-650 tonnes/year of uranium, which will nearly double in the next 15 months.

Nuclear power share is currently about 3%.

Fast Breeder Reactors: The advantage with these reactors is that they will use the reprocessed fuel from the first stage reactors. Also, the third stage development, which uses locally available thorium, can increase nuclear potential from the current 10,000 MW to about 500,000 MW.

Wind energy

Worldwide installed capacity is about 67,000 MW.

India’s installed capacity is 5,200 MW and is the 4th largest in the world.

Wind has unpredictable and very low load factors – for India it is estimated to be in the 20-25% range.

A windmill can be setup in a matter of weeks in contrast to other modes which take years to install.
