| 6.5 |
Reasonable Return
With regard to reasonable return it is clarified
that the same has to be calculated on the basis of the capital
base arrived at in accordance with the provision of Sixth
Schedule to the Supply Act, 1948. |
| 6.6 |
Treatment of Working Capital |
| 6.6.1 |
The Commission believes
that the companies must commit themselves to a higher level
of efficiency, bring loan to meet the working capital needs
so that the transmission utility and the generators are
not starved of funds. There is a gap between the revenue
billed and the revenue realised due to inefficiency on the
part of the licensees for failing to take appropriate and
expeditious steps like disconnection in time or initiation
of civil suits to realise the arrear dues. Domestic, irrigation
and agricultural consumers are not required to pay any DPS
for delay in payment, whereas small and medium industries
and other categories only pay one time DPS. This is a disincentive
for revenue collection especially when the licensees are
not capable of realising the dues after the due date of
payment is over. The Commission also may at appropriate
time consider for levy of DPS for those consumers who are
at present not covered under DPS for delay in payment. |
| 6.6.2 |
The distribution companies
have failed to bring required working capital to ensure
cash balance in the system to meet all expenses. The licensee
can get rebate on prompt payment from GRIDCO @2% per month,
which will reduce its power purchase liability. In a sense
if the licensee arranges working capital from the commercial
and financial institutions they can save not only the DPS
but will earn a rebate from the GRIDCO that will compensate
the interest on working capital and may accrue some revenue
in the form of rebate. |
| 6.7 |
T&D loss |
| 6.7.1 |
The next issue is determination
of the total cost of distribution and retail supply. The
supply business requires purchase of power by the DISTCOs
from the transmission company (GRIDCO) for supply to consumers.
The energy received at grid sub-stations at 33 kV by the
DISTCOs and supplied to the end-use consumers at different
voltage levels entails both technical and commercial losses.
The Commission hitherto have been following the concept
of determination of power procurement after applying a normative
loss level to the total power proposed to be sold by the
licensee, irrespective of the quantum of actual power purchase
by DISTCOs from GRIDCO. This quantum of power purchase is
metered in each grid sub-station and is reflected in the
various data recorded in the energy billing centre (EBC)
of GRIDCO and also in the BST bill of GRIDCO raised on DISTCOs.
|
| 6.7.2 |
The World Bank Staff
Appraisal Report of April 1996 projected different levels
of transmission and distribution loss for the year 1996-97
to the FY 2002-03 based on the studies made by a group of
reputed consultants. The Commission while approving the
tariff application in the year 1997-98 took cognizance of
these projected loss figures. While adopting a loss level
of 35% for the year 1997-98, the Commission went by the
estimate of 34.8% made in the SAR as against the claim of
47% made by GRIDCO for that year. The projections made in
the SAR, the level of T&D loss as established by the
audit report of GRIDCO gives a wide disparity in the projections
and actual performance as can be revealed from the table
below.

The members the Commission
Advisory Committee specifically discussed the issues of
high percentage of T&D loss, Distribution loss, poor
performance of Distcos, subsidy, cross-subsidy. Majority
of the members suggested that the recommendation of the
Kanungo committee should be kept in view while finalising
the tariff and revenue requirement of DISTCOs as neither
the Government of Orissa filed any objection nor depute
any representative to appear in the hearing. Members also
advocated in favour of uniform retail tariff for the whole
State. Some of the Members raised issues specific to the
interest groups they represent. But there was near unanimity
with regard to the certain issues. It was felt that T&D
loss was still high and while fixing the target level of
loss, the Commission should not go back to the level already
set. Rather the target level of loss be set at still lower.
It was also felt that installation of meters and consumer
services were far from satisfactory. Most of the members
opined that there should be thorough scrutiny on the input
cost of the licensees, while Some suggested that depreciation
should not be charged on the assets those have already outlived.
The Chief Electrical Engineer, S.E. Railways raised certain
vital issues to be tackled while passing this tariff order
to give benefit to the Railways. |
| 6.7.4 |
The objectors in general
were of the opinion that the adoption of a uniform loss
figure for the four distribution companies with a different
load mix was hiding the inefficiency of the companies with
higher components of HT and EHT load. EHT component of load
makes a big difference to the overall loss figure for the
company as loss in EHT category is practically negligible.
The overage loss as a percentage of the total power procurement
from the GRIDCO by DISTCOs as well as the direct sale figures
at EHT as projected by the four DISTCOs are given in the
table for the FY 2001-02.(RR02-03 filing of DISTCOS).

Some of the objectors
have pointed out that the distribution loss is being computed
after taking into account even the zero loss EHT energy
input into the system to show a reduced level of loss. The
total power sale to a DISTCO is arrived at the Energy Billing
Centre of GRIDCO by integrating the EHT drawal at 132/220
kV and bulk power drawal at 33 kV in any grid sub-station.
Therefore, sale at EHT can be taken out from the total power
purchase figures to determine the energy input to various
DISTCOs for supply to HT and LT consumers. If the EHT sale
projected by the four DISTCOs are taken out from the total
sale projected by these companies then the distribution
loss as the percentage loss of HT and LT input works out
to 53.3% for NESCO, 56.3% for WESCO, 44.1% for SOUTHCO and
48.2% for CESCO with an overall loss figure of 50.6% for
the State as a whole under HT & LT category. |
| 6.7.6 |
As we will be determining
the energy input into the DISTCOs system based on the billing
figures of GRIDCO for the FY 2001-02, it will be appropriate
to determine the loss as a percentage of HT and LT input
after deducting the direct sale at EHT to show a comparative
picture of performance of the four DISTCOs and also plan
for bringing down the distribution loss at the HT &
LT level, which will ultimately bring down the overall distribution
loss in a DISTCO. |
| 6.7.7 |
Identical comparison
can be done for the FY 2002-03 by determining distribution
loss as a percentage of HT and LT input. |
| 6.7.8 |
The Commission in the
tariff order dtd.19.01.2001 had observed that the task of
fixing a level of loss in the absence of verifiable and
reliable data has led it to apply a value judgement that
should be fair, reasonable and financially sound. Any arbitrariness
on the part of the Commission will either affect the financial
viability of the licensee or sustain undue burden on the
consumers. |
| 6.7.9 |
The Commission had also
observed in the last tariff order that the high T&D
loss is not an isolated phenomena in Orissa. Higher level
of loss figures are being gradually disclosed in all most
all the reforming states in the country. The Commission
was also of the view that the benchmark of T&D loss
at 35% was as a measure of performance perceived to be unrealistic
and unacceptable by GRIDCO and the DISTCOs. The World Bank
on whose SAR Commission relied in fixing an overall loss
level of 35% in FY 1997-98 subsequently came out in its
midterm review report dtd.31.10.1998 that it underestimated
the actual loss level. The World Bank states "Consultation
with the Commission on the issue of recognizing the actual
system loss levels and pass through of prior years' financial
losses, given that we all so severely underestimated GRIDCO's
system losses in 1996 and set unachievable performance targets".
|
| 6.7.10 |
Therefore DISTCOs all
along complained about to unrealistic loss level of 35%
adopted by the Commission while adopting a loss level of
34% for the FY 2000-01 including the losses at EHT transmission
system of 3.7%, the Commission had directed the DISTCOs
during the course of the hearing to carry out pilot studies
within a period of six months from April, 2001 to September,
2001 and submit the same to the Commission for its appraisal
while determining the target level of loss reduction from
year to year. The Commission is constrained to place on
record the utter failure of licensees to address this most
important and crucial issue which was being raked up by
them time and again. DISTCOs have not initiated any concerned
and vigorous effort to fix meters in feeders, LV side of
transformer and consumers served by the feeder to ascertain
the actual level of loss. |
| 6.7.11 |
Due to insistence by
Commission the DISTCOs started determination of loss on
a selected feeder. It was a much delayed exercise by all
the licensees. Also Commission's effort to engage outside
consultants to oversee the pilot loss study could not take
off due to the financial problem of the licensees. Only
WESCO initiated a study by engaging an outside agency. |
| 6.7.12 |
However, the Commission
with the assistance of the Department for International
Development (DFID) has conducted pilot study in one 11 kV
feeder for WESCO, NESCO and SOUTHCO and two feeders of CESCO
by appointing its own consultants. The report of this pilot
study demonstrates that there is ample scope and opportunity
for quick reduction of loss by the DISTCOs. |
| 6.7.13 |
The distribution companies
while submitting the business plan for a period of 5 years
to the Committee of independent expert in the month of October,
2001 have supplied the following distribution loss figures
for the year 2001-02 to 2004-05:-

This, however, excludes the transmission

| 6.7.15 |
The committee, however,
accepted a distribution level loss of 42.21% for the base
year of FY 2001-02 after hearing the DISTCOs and suggested
reduction of distribution loss by 5% each year from FY 2002-03
to reach a level of 22.21% in the year 2005-06. Similarly,
the committee had also approved a reduction of transmission
loss at a rate 0.3% each year from FY 2002-03 till the losses
reach 3.7% by 2005-06. This is projected in the table below.

The committee of independent
experts appointed by the Government of Orissa to review
the power sector reform in their report have suggested reduction
of distribution loss at the rate of 5% per annum. The pilot
study conducted by the Commission brings out very clearly
that the scope of reduction of distribution loss is enormous
provided the companies take effective steps such as technical,
financial and managerial decisions for reduction of distribution
loss. Any number of alibis expressing inability for not
reducing the distribution loss are not acceptable to the
Commission. Besides higher level of loss found out on the
basis of pilot study is purely indicative as the number
of feeders selected were very few compared to the existing
number of feeders. Pilot study results cannot be taken as
basis of loss levels existing in different DISTCOs, as study
on one feeder out of hundreds of feeders in the company
with varied load mix, concentration of loads, length and
size of feeders cannot be a representative one. But this
study brought to the fore very interesting facts like direct
tapping of 11 kV feeder by industrial consumers, by-passing
of meter CTs. It so happened in some areas where pilot study
was being taken up, the consumers locked their houses and
went away forbidding the utility staff and Commission consultant
to check the status of the meter. Pole scheduling in the
study area revealed unauthorized abstraction of energy by
the illegal consumers, consuming energy far more in excess
of what was shown in the consumer ledger of the DISTCOs. |
| 6.7.18 |
In the 2001-02 tariff
filing, WESCO had reported a loss level of 38% for that
year. But while submitting the revenue requirement application
FY 2002-03, WESCO have reported distribution loss for the
year 2001-02 as 45%. This kind of irresponsible reporting
for a particular year has been made within an interval of
3 months. It implies that the DISTCOs have demonstrated
a very casual attitude in projecting the figure to the Commission
for the purpose of determination of tariff or revenue requirement.
The case of other companies are also not different. |
| 6.7.19 |
The Commission accepts
the distribution loss figure as approved by the Kanungo
Committee as 42.21% for the FY 2001-02 which is treated
as the base year. This figure of 42.21% represents the overall
average distribution loss for the entire State but varies
across the four distribution companies. The variation in
loss figures across the DISTCOs are exhibited in Table-12.
The Commission also adopts the recommendation of the committee
for reduction of distribution loss at least at the rate
of 5% per annum from 2001-02 to 2002-03. The Commission
therefore directs that for the purpose of determination
tariff and the revenue requirement the rate of loss reduction
will be calculated at the rate of 5% (overall average for
the state) starting from the FY 2001-02 and 2002-03. Accordingly,
the following loss figures are approved for the aforesaid
purpose for the year 2001-02 and 2002-03. While formulating
the multi-year tariff proposed to be effective from 01.04.2003,
this aspect of loss reduction along with collection efficiency
etc will be decided for subsequent years.

Commission wants to
make it expressly clear that there is no shortcut way unless
a systematic drive is made to reduce the distribution loss.
This should necessarily include metering of 11 kV feeders,
metering at LV side of transformers, pole scheduling, verification
if deemed necessary of consumer connected loads, rectification
or replacement of consumer meters so that each feeder is
converted to a Profit Centre as has been very aptly stated
by the Ministry of Power, GoI, which is allotting large
sum of funds to meet cost of metering etc. to achieve the
goal in a time bound manner, which will be available through
State Govts. to utilities and SEBs under APDRP programme.
|
| 6.7.21 |
There are 846 Nos. of
33/11 kV feeders in the State under the four DISTCOs. There
are about 900 field sections in the DISTCOs. This means
that there may be 1 to 2 Nos. of 11 kV feeders under each
section and 1 No. of 33 kV feeder and 9 Nos. of 33/11 kV
transformers and at least 30 Nos. of distribution transformers
in each feeder. Once members and other supporting staff
including MRT personnel are made available, it would be
possible to complete within one year for monitoring of all
feeders along with complete pole scheduling leading to identification
and regularisation of unauthorised connection. Progressive
achievements will bring substantial in reduction of loss
in feeders. |
| 6.7.22 |
Commission, among other
things shall attach highest priority on these aspects and
would expect the licensee to aggressively start taking up
related activities. Commission would, on its part approach
DFID to provide support to temporarily hire services of
technical personnel by the Commission to oversee the progress
made in this regard by the licensee on a day to day basis. |
| 6.7.23 |
Although the Commission
in deference to the spirit of OER Act, 1995 would have liked
for a hands-off regulation while dealing with DISTCOs. But
it finds to its dismay that utilities have taken advantage
of this liberal gesture and have done precious little to
address this single major factor of loss reduction which
constitutes a menace to the viability of the power sector.
Therefore, Commission would closely associate itself in
monitoring the activities of DISTCOs in this regard. |
| 6.7.24 |
As indicated in para
6.7.16 the loss as a percentage of HT & LT input for
the year 2005-06 approved by the Kanungo Committee should
be targeted at 28.39% to be attained by all the DISTCOs. |
