According to the Load Generation Balance Report for 2009-10 released by Central Electricity Authority, The eastern region will be surplus in energy to the extent of 2.4%. All other regions will face energy shortage varying from 7.7% in the northern region to 15.2% in the western region. The peak shortage will prevail in all regions varying from 6.3% in the eastern region to 15. 5% in the northern region.
According to CEA, the energy requirement is estimated at 8,40,544 million units(mu) and peak demand at 1,18,794 mw in 2009-10 while the availability will be 7,62,115 mu (-9.3%) and 1,03,816 mw (-12.6%)respectively.
There will be surplus energy in northern region states having predominantly hydro systems during the monsoon months while shortage conditions would prevail during winters.
States with hydel power such as Himachal Pradesh, Jammu & Kashmir and Uttarakhand will be surplus in energy during monsoon period, while they will face severe shortage conditions during the winter low flow months when the generation from hydro schemes dwindles to the minimum. However, Sikkim will have both peaking and energy surplus in all the months.
The West Bengal will have surplus both in terms of capacity and energy. Moreover, Tripura and national capital region of Delhi will have surplus energy on annual basis but have peaking deficit. Rajasthan will have energy surplus in all months except summer months and face peaking shortage.
The report also mentioned at length the actual power supply position in 2008-09. During the previous fiscal, though the total ex-bus energy availability increased by 3.76% over 2007-08 and the peak met increased by 6.6%, the shortage conditions pervailed in the country both in terms of energy and peaking availability.
The energy requirement registered a growth of 5.10% against the projected growth of 8.15% and peaking demand reported a growth of 0.87% against the projected growth of 10.33% in 2008-09.
The total inter-state and inter-regional exchanges during 2008-09 were 34,647 mu, which helpted in mitigating the shortages in various states/systems.
Meanwhile, CEA said there will be a capacity addition of 12,770 mw during the year 2009 -10 comprising 11,446 mw of thermal, 664 mw of hydro and 660 mw nuclear power stations has been considered.
