New Delhi: India may face electricity shortage of over 10 percent this fiscal as fuel shortage and environmental issues have hit the power sector. 

The expected power shortage in the current financial year is higher than the deficit of 8.5 per cent seen in 2010-11.

"The anticipated energy and peaking shortage in the country would be 10.3 per cent and 12.9 per cent, respectively (in 2011-12)," the Central Electricity Authority has said.

Going by the projections, there would be an electricity supply shortfall of 96,367 million units in 2011-12.

During this fiscal, the requirement is expected to be higher at 9,33,741 million units as against an estimated availability of 8,373,74 million units.

"All regions would face energy shortage varying from 0.3 per cent in the North-Eastern region to 11 per cent in the Western region," CEA said in a recent report.

The country's power requirement is on a rise considering the good economic growth. However, availability of electricity is low, due to delays in some projects as well as longer time taken for stabilisation of power projects, according to CEA officials.

They noted that usually actual electricity shortage would be lower than estimated figures, since the projection takes into account extreme scenarios such as environmental changes (mainly in hydro projects).

As per the CEA, in previous fiscal, energy requirement grew 3.7 per cent as against the projection of 5.6 per cent while peak demand rose 2.6 per cent compared to the estimated 6.5 per cent.

The gross energy generation target for the current fiscal is 8,55,000 million units, with thermal power plants anticipated to generate 7,122,34 million units.

Coal supply concerns and environmental hurdles have resulted in many power projects getting delayed. Such issues have adversely impacted the government's ambitious capacity addition plans.
