As many as 17 states are expected to witness significant power supply shortages this fiscal, with Tamil Nadu projected to receive less than three-fourth of its total electricity requirements.
Among the 17 states, the worst hit would be the three southern states of Tamil Nadu, Kerala and Karnataka.
Latest estimates from the Central Electricity Authority (CEA) show that the southern region — comprising four states and one union territory — is likely to see a power deficit of 19.1 per cent in 2013-14.
In signs that electricity supply is worsening in the southern region, the power deficit would be higher this fiscal compared to deficit of 15.5 per cent in 2012-13 period.
The projections come against the backdrop of acute power shortages in various parts of the country due to a slew of factors including fuel scarcity, poor financial health of discoms (state power distribution companies) and transmission woes.
Tamil Nadu, Kerala, Karnataka, Andhra Pradesh and Union territory of Puducherry make up the southern region.
While the deficit in Tamil Nadu is estimated to be around 26.5 per cent, the shortage in Kerala would be around 24.8 per cent, Karnataka (23.2 per cent) and Andhra Pradesh (9.1 per cent). Puducherry is projected to have a electricity supply surplus of 9.9 per cent.
Other states that are projected to see substantial electricity supply shortages include Punjab (19.7 per cent), Assam (19.7 per cent), Bihar (19 per cent), Uttar Pradesh (18 per cent), Arunachal Pradesh (17.7 per cent), Uttarakhand (15.4 per cent), Rajasthan (15.1 per cent) and Tripura (13.5 per cent).
As per CEA, the planning body for the power sector, Maharashtra with a deficit of 9.8 per cent, Goa (4.5 per cent), Jharkhand (6.8 per cent), Nagaland (5.6 per cent) and Orissa (0.8 per cent), are also among the 17 states that are expected to witness electricity shortages. The figures are based on the gap in supply and demand calculated on million units basis.
