The power sector seems to have
fared slightly worse during the
first seven months of FY13,
compared to what Central Electricity
Authority had projected in its Load
Generation Balance Report. Thus,
actual average deficit was around 8.6
per cent over the period, as compared to
8.5 per cent expected in LGBR. Actual
power availability was assessed better
at 534 BU during April-October,
against 522 BU factored in LGBR. But,
then, requirement of around 584 BU
over the period also exceeded the 522
BU expected in LGBR. The feat on
deficit for April-October, however,
masks intra-period volatility of power
sector. Thus, due to southwest
monsoon playing truant on the one
hand and higher power requirement on
the other, actual deficit had worsened
from 8.6 per cent in June to 8.9 per cent
in July and 9.1 per cent in August, as
compared to easing in deficit from 7.7
per cent to 6 per cent expected in LGBR
over the period. However, lower deficit
in April, May and October due to
subdued growth in requirement helped
make up for the lost ground. Peak
demand shortage was expected to be
around 10.4 per cent, against 9 per cent
for April-October period as per
provisional data from CEA.
LGBR projections seem to have gone
wrong during April-October,
particularly in western region, which
is the second highest power consumer
region in the country. The region ran
power deficits throughout the seven
months period, against surpluses
assumed in LGBR, with actual average
deficit over the period working out to
3.1 per cent, against a surplus of 1.3
per cent assessed in LGBR. Power
requirement for the region turned out
to be more, while availability fell
marginally short. The deficit in
northern region, the most power
consuming region, turned out to be
around one percentage point less,
while that in southern region was over
three percentage points lower. In
northern region, actual deficit was
lower than projection in April, May
and October, whereas it surpassed
projections in June to September due
to lacking southwest monsoon rains.
Actual deficit fell short of projected
deficit consistently during April-
October in the southern region, even
as it exceeded projected levels in
eastern region in all the seven months
barring June.

The gross energy generation in the
country has been assessed at 930 BU for
2012-13 in LGBR, which has factored
for this purpose power availability
from various stations in operation
including CPP and non-conventional
energy, fuel availability, proposed
maintenance schedule of the units,
anticipated water availability at
hydropower stations, as also a capacity
addition of 17,956 mw over the year,
comprising 15,154 mw of thermal, 802
mw of hydro and 2,000 mw of nuclear
power. The first seven months of the
year have seen 9,036 mw of new
capacity, comprising 8,735 mw of
thermal and 301 mw of hydro power.
The country is to tackle average
deficit of 9.3 per cent and a peak
demand/availability deficit of around
10.6 per cent over 2012-13. Power
requirement is expected to go up by
around 5.1 per cent over the year and
total ex-bus energy availability (i.e.
energy dispatched by the generating
station after internal consumption) by
4.1 per cent, which would lead to a
rather sharp worsening in energy
deficit to 9.3 per cent from 8.5 per cent
average in the preceding two years.
Peak demand/availability deficit is to
broadly remain same. Western region is expected to be self-sufficient in energy
with peak demand deficit too
remaining subdued at 3.2 per cent. The
feat reflecting robust growth in power
availability, but surprisingly a nominal
decline during 2012-13 is remarkable
when viewed against average deficit of
10+ per cent in preceding five years. By
the way, the region recorded 3.1 per
cent deficit, against 1.2 per cent surplus
projected in LGBR during the first
seven months of the fiscal. Northern
region is to face 10.6 per cent energy
deficit and 12.3 per cent peak demand
deficit, southern region 19.5 per cent
energy and 26.3 per cent peak demand
deficit and eastern region 4.8 per cent
energy deficit and a nominal surplus in
peak demand requirement.
The average power deficit for the
country was to fall from 11 per cent in
April to 6 per cent by August and
resume uptrend subsequently to peak
at 13 per cent in February as per LGBR.
Energy requirement as also availability
would be the maximum in March,
which would see energy shortage of
11.6 per cent. Seven out of 12 months
during 2012-13 would see double-digit
peak demand/availability deficit in the
country.
STATE-WISE DETAILS
Twenty five states (or UTs) would have
energy deficit and 30 states would have
peak deficit of varying degrees. Nine
states would have net surplus energy
and five would have peak surplus on
annual basis.
Hydro-rich states having run of river
schemes on the Himalayan rivers viz.
Himachal Pradesh, Jammu & Kashmir,
and Uttarakhand would be surplus in
energy during monsoon period, while
they would face severe shortage
conditions during the low inflow
winter months when the generation
from hydro schemes dwindles to the
minimum. DVC and Sikkim would
have both peaking and energy surplus
on annual basis.

Chandigarh, Haryana,
Chhattisgarh, DNH, Manipur and
Tripura would have surplus in terms of
energy whereas Himachal Pradesh and
Orissa will be in comfortable position
in terms of peak on annual basis.
All other states in the country would
have electricity shortages of varying
degrees both in term of energy and
peaking.
In a major transformation,
Chhattisgarh has emerged as the
largest power surplus state, with
surplus projected at 30 per cent during
the current fiscal, against shortfalls,
though nominal, in earlier years. Power
availability is expected to double to
31,222 MU during the year which
would easily take care of 59 per cent
increase in power requirement. The
state recorded 1.7 per cent power
shortage during April-October, though
it was expected to be power surplus
throughout the year.
Maharashtra, the largest consuming
state, is to face 12.1 per cent deficit over
the current fiscal, reducing from 16.6-
16.7 per cent in 2010-11 and 2011-12.
The state's power requirement is
projected to go down 15 per cent,
whereas the availability is feared to
deteriorate by 10 per cent. The deficit
was to range between 8 per cent in June
to 18 per cent in August. The state
faced a much lower deficit of 3.5 per
cent during April-October 2012.
Uttar Pradesh is projected to face a
much worse 19 per cent deficit,
compared to 11 per cent in 2011-12, due
to a much faster increase in power
requirement and a little lower power
availability. The deficit was to range
between 13 per cent in March 2013 to
27 per cent in September. The state
faced 16 per cent energy deficit during
April-October 2012.
The deficit in Tamil Nadu is expected
to worsen three times to 30 per cent
due to 8 per cent increase in
requirement, against a decline in
availability. The deficit was to remain
well over 20 per cent over the months
(barring 19 per cent in June). The state
faced 16 per cent deficit during April-
October.
Andhra Pradesh is projected to face
23 per cent deficit, three times the level
in 2011-12 as its power needs were expected to be self-sufficient in energy
with peak demand deficit too
remaining subdued at 3.2 per cent. The
feat reflecting robust growth in power
availability, but surprisingly a nominal
decline during 2012-13 is remarkable
when viewed against average deficit of
10+ per cent in preceding five years. By
the way, the region recorded 3.1 per
cent deficit, against 1.2 per cent surplus
projected in LGBR during the first
seven months of the fiscal. Northern
region is to face 10.6 per cent energy
deficit and 12.3 per cent peak demand
deficit, southern region 19.5 per cent
energy and 26.3 per cent peak demand
deficit and eastern region 4.8 per cent
energy deficit and a nominal surplus in
peak demand requirement.
The average power deficit for the
country was to fall from 11 per cent in
April to 6 per cent by August and
resume uptrend subsequently to peak
at 13 per cent in February as per LGBR.
Energy requirement as also availability
would be the maximum in March,
which would see energy shortage of
11.6 per cent. Seven out of 12 months
during 2012-13 would see double-digit
peak demand/availability deficit in the
country.
Hydro-rich states having run of river
schemes on the Himalayan rivers viz.
Himachal Pradesh, Jammu & Kashmir,
and Uttarakhand would be surplus in
energy during monsoon period, while
they would face severe shortage
conditions during the low inflow
winter months when the generation
from hydro schemes dwindles to the
minimum. DVC and Sikkim would
have both peaking and energy surplus
on annual basis.
Chandigarh, Haryana,
Chhattisgarh, DNH, Manipur and

faced 16 per cent energy deficit during
April-October 2012.
The deficit in Tamil Nadu is expected
to worsen three times to 30 per cent
due to 8 per cent increase in
requirement, against a decline in
availability. The deficit was to remain
well over 20 per cent over the months
(barring 19 per cent in June). The state
faced 16 per cent deficit during April-
October.
Andhra Pradesh is projected to face
23 per cent deficit, three times the level
in 2011-12 as its power needs were expected to mount 8 per cent, while the
availability is to fall around 10 per cent.
The deficit in the state was to range
between 16 per cent in August to 29 per
cent in March. The average deficit in
Andhra Pradesh over April-October
worked out to around 16.7 per cent.
Energy deficit in Karnataka is to fall
from 11 per cent to 1.3 per cent, due to
sharp increase of around 13 per cent in
power availability. The state was to be
surplus in energy in four out of 12
months. Actual deficit in the state over
April-October was, however, much
more at 13.5 per cent, against around
twice the measure expected in LGBR.
Gujarat would encounter 5 per cent
shortfall, against a nominal shortfall in
2011-12. The state suffered only
nominal shortfall during the first seven
months of the current fiscal.
METHODOLOGY
The annual Load Generation Balance
Report (LGBR) for the year 2012-13,
the thirty first publication in the series
on the subject, covers the month-wise
anticipated energy requirement and
availability (in MU) as well as peak
demand and availability (in MW) for
the year, considering all India annual
generation target of 930 BU, finalized
after detailed discussions with the
state electricity boards/ utilities and
Central/state/private generation
companies and availability from
import of power from generation
projects in Bhutan and also availability
from non-conventional and renewable
energy sources in the country.
The net energy availability (ex-bus)
corresponding to gross energy target as
finalized in CEA/ Ministry of Power is
computed for all generating plants
taking into consideration the
normative auxiliary consumption. The
energy availability in each state is
worked out at respective Regional
Power Committee Secretariat as under:
- Generation from generating plants
owned by the state
- Share of power from the common
projects
- Allocation of firm power from
Central generating stations
- Allocation from unallocated quota
of power from Central generating
stations as per the allocation in
vogue
- Energy import-export under long
term bilateral agreements
The short-term exchange as per
bilateral contracts and exchange of
energy through exchanges is not taken
into consideration. Depending upon
the actual exchanges and over
drawal/under drawls of energy against
schedule, the availability of power to a
state may change.
Assessment of unrestricted peak
demand and unrestricted energy
requirement and peak and energy
availability of constituent states of
each Region has been done by the
respective Regional Power
Committees (RPCs) after review of
the projections made by the
constituent states, past data and the
trend analysis. The inputs provided by
the RPCs are analysed and the
anticipated month-wise power supply
position for each state, region and the
country are prepared by Grid
Management Division of CEA. The
estimated peak availability is
calculated from the units available for
generation for various utilities in
different months after considering
schedule maintenance in the RPC
forum and auxiliary consumptions.
The anticipated electricity shortages
or surpluses are calculated as a
difference between the net
unrestricted anticipated requirement
and the net anticipated availability in
terms of energy and peak demand.
The LGBR projections have tended
to be relatively close to actual
performance. Thus, actual power
availability in FY12 was 2.4 per cent
above the projection in FY12 and 0.6
per cent in FY11, while it fell 2 per cent
short of projection in FY10. Actual
power requirement surpassed
projection in FY12, while it fell 1-2 per
cent short of projection in earlier two
years.
In eastern region, actual feat fell
short of LGBR projection in all
parameters, namely energy
requirement, availability, peak demand
ad peak demand met in 2011-12,
whereas in southern it surpassed LGBR
expectations.
XII PLAN PROJECTIONS
As per 18th Electric Power Survey (EPS)
report, the projected all-India peak
demand and energy requirement at the
end of 12th Plan (2016-17) is 199,540
mw and 1354.874 BU respectively at
power station bus-bar. To meet this
projected demand, capacity addition of
88,537 mw is required during 12th Five
Year Plan from conventional sources
including thermal and hydro. In
addition, the installed capacity of gridinteractive
renewable sources of power
generation is expected to be about
54,000 mw at the end of XII Plan
period. This capacity is expected to be
adequate to generate power to meet
the stipulated energy requirement
(net) at the end of the current Five Year
Plan period, according to the
information recently furnished in
Parliament.
