Category-wise Energy Sales
3.4 The Commission had approved energy sales of 6684 MU, 7524 MU, and 8399 MU
for FY 2016-17, FY 2017-18, and FY 2018-19, respectively in the MYT tariff order
dated March 31’ 2017. The Commission, subsequently approved energy sales of
6526 MU in the truing-up for FY 2016-17. Also, the energy sales were revised to
7107 MU in the APR for FY 2017-18 and 7784 MU for FY 2018-19 as approved by
the Commission in the tariff order dated March 19’ 2018.
3.5 The Petitioner submits that the actual energy sales for FY 2017-18 are 6814 MU
Assam Power Distribution Company Limited (APDCL) Page 12MYT Petition for the Control Period FY 2019-20 to FY 2021-22
as against 7107 MU approved in the APR for FY 2017-18. It is to be noted that
actual energy sales for FY 2017-18 are more than the actual energy sales for FY
2016-17, both for the LT and HT category. The LT sales for FY 2017-18 has
shown an increase in sales of ~6% over LT sales for FY 2016-17 and HT sales for
FY 2017-18 has shown an increase in sales of 1% over HT sales for FY 2016-17.
3.6 The Petitioner submits that it has to complete the remaining household
electrification by December 2018 as per the provisions of the SAUBHAGYA
scheme. This will increase the household consumption, particularly in the rural
areas from FY 2018-19. All efforts are being made to achieve the stipulated
timeline. 9,62,704 households are pending electrification as on 29th November’
2018 in Assam (as per figures on SAUBHAGYA portal). The pending
electrification of households is to be completed by December2018. We have
considered that this addition in households will primarily be in the Jeevan Dhara
category. The Petitioner has considered that this addition in households will
result in additional ~487 MU of energy sales in the Jeevan Dhara category during
FY 2018-19. This additional consumption has been considered over and the
above the 4 year CAGR growth applied to the Jeevan Dhara category during FY
2018-19. The actual impact of the increase in sales due to the SAUBHAGYA
implementation will be considered at the time of true-up of ARR for FY 2018-19.
3.7 The projections of energy sales for FY 2018-19 have been revised based on
actual energy sales for FY 2017-18 and actual performance in H1 of FY 2018-19.
For rest of the consumer categories, energy sales have been projected keeping
historical growth rates in mind and projecting the 3 year, 4 year, 5 year CAGR
along with the Y-o-Y growth seen in the consumer categories. Reasonable
estimates about the growth rates of the various consumer categories have been
made to arrive at the energy sales for FY 2018-19. Accordingly, the Petitioner has
estimated energy sales of 7749 MU in the APR for FY 2018-19.
3.8 For the years of the control period from FY 2019-20 to FY 2021-22, the
Petitioner has considered the historical 4 year CAGR for estimation of sales to
Jeevan Dhara category. For Domestic A category the average YoY growth seen
during last two years, has been applied to estimate the sales for the control
period from FY 2019-20 to FY 2021-22.
3.9 For rest of the consumer categories, the energy sales have been projected
keeping historical growth rates in mind and projecting the 3 year, 4 year, 5 year
CAGR along with the Y-o-Y growth seen in the consumer categories. Reasonable
estimates about the growth rates of the various consumer categories have been
made to arrive at the energy sales forecast for the control period from FY 2019-
20 to FY 2021-22. In case the growth trend is recent years was negative, we
have considered 0% growth rate for those consumer categories. The growth rate
as observed by the trend of CAGR has been adjusted in line with the recent YoY
Assam Power Distribution Company Limited (APDCL) Page 13MYT Petition for the Control Period FY 2019-20 to FY 2021-22

3.12 Accordingly, the Petitioner requests the Hon’ble Commission to approve the
energy sales as estimated above for the MYT control period from FY 2019-20 to
FY 2021-22.
Distribution Loss Trajectory
3.13 The Commission in the business plan order dated September 1’ 2016 had
approved distribution loss of 17.35%, 17.10% and 16.85% for FY 2016-17, FY
2017-18 and FY 2018-19 respectively.
3.14 The Commission during true-up of FY 2016-17 vide tariff order dated March 19’
Assam Power Distribution Company Limited (APDCL) Page 15MYT Petition for the Control Period FY 2019-20 to FY 2021-22
2018 approved the same distribution loss at 17.35% as against actual
distribution loss of 17.89% for FY 2016-17. The Commission maintained the
distribution loss at 17.10% during APR for FY 2017-18 and 16.85% during
revised ARR for FY 2018-19 (as per tariff order dated March 19’ 2018).
3.15 It is to be submitted that the Petitioner has been praying for consideration of loss
at actuals with detailed justification on regular basis.
3.16 The APDCL during FY 2017-18 has achieved actual distribution loss of 17.64%
against the target of 17.10% even with various constraints i.e. adverse LT: HT
ratio, incremental sale to LT consumers, old infrastructure etc. The past years
actual distribution loss of APDCL against the target approved by the Commission
is shown in the following table:
Table 3: Target vis-à-vis actual distribution loss of APDCL
Year Approved Loss (%) Actual Loss Level (%)
2005-06 29.95 31.10
2006-07 30.71 29.43
2007-08 25.05 27.32
2008-09 24.24 24.32
2009-10 22.60 26.06
2010-11 21.60 25.44
2011-12 20.60 26.61
2012-13 19.60 25.85
2013-14 18.60 24.11
2014-15 18.60 21.14
2015-16 17.60 18.12
2016-17 17.35 17.89
2017-18 17.10 17.64
3.17 It is seen that over the years the utility has been able to bring down the losses
gradually. It is pertinent to mention that with specific programs like DSM
initiatives, creation of dedicated cells to monitor high value consumers etc.
APDCL has been able to bring down the loss level significantly even with
restricted resources. The Petitioner, humbly submits that despite the best efforts
of the utility to achieve the target distribution losses, it is getting much more
difficult to reduce the distribution losses now at the same rate as achieved in the
past years.The HT: LT ratio is getting adverse every year as LT sales are
increasing on account of extensive rural electrification and HT sales are not
increasing at the same rate as it is impacted due to other factors like lack of
industrial growth in the state, etc.
3.18 Year-on-year sales mix of APDCL and corresponding distribution losses of APDCL
are as depicted below:
Assam Power Distribution Company Limited (APDCL) Page 16MYT Petition for the Control Period FY 2019-20 to FY 2021-22
Table 4: LT: HT ratio vis-à-vis actual distribution loss of APDCL

2012-13 2176(52%) 2029(48%) 25.85
2013-14 2593(54%) 2170(46%) 24.11
2014-15 3228(59%) 2257(41%) 21.14

2016-17 4270(65%) 2256(35%) 17.89
2017-18 4534 (67%) 2280 (33%) 17.64
3.19 It is understood that HT: LT ratio has a key impact on overall distribution losses
of the state and with the present trend of inverse HT: LT ratio, the distribution
loss targets stipulated for the current control period are difficult to achieve.
Losses increase with increase in LT consumption at the same performance levels.
3.20 The distribution loss scenario of APDCL is also to be seen from the aspect of
overall situation prevailing in some parts of the state. It may be seen that in
predominantly urban areas as well as areas without any social disturbances, the
utility was able to achieve distribution loss far below the approved loss levels.
However, in some areas where the situation is beyond reasonable control of the
licensee, the losses have crossed the approved limit. Further, consumer
behaviour of certain areas under APDCL is at variance from others. Frequent
bandh as well as perennial natural calamities in some part of the State affects the
performance in these areas resulting in higher losses.
3.21 The Petitioner as per first half actual performance in FY 2018-19 has not been
able to achieve the targeted distribution loss of 16.85%. The actual distribution
loss as per H1 of FY 2018-19 is 18.34%. The Petitioner notes that as per the
UDAY MoU, the distribution licensee is to achieve the AT&C loss target of 15% by
FY 2019-20. Considering the collection efficiency of 99.50%, the UDAY MoU had
stipulated the target distribution loss of 14.57% by FY 2019-20. The Hon’ble
Commission in the last tariff order dated March 19’ 2018 had maintained the
distribution loss trajectory as approved by the Commission in the business plan
order dated September 1’ 2016 and accordingly approved the distribution loss of
16.85% for FY 2018-19. As per the latest communication received from the
Hon’ble Commission vide letter dated June 8’ 2018, the Commission is planning
to fix target AT&C loss of 15% for FY 2019-20 and gradually reducing it to 14%
Assam Power Distribution Company Limited (APDCL) Page 17MYT Petition for the Control Period FY 2019-20 to FY 2021-22
by FY 2021-22. It is to be noted that the Commission has stipulated a very steep
reduction in target distribution losses for FY 2019-20 at 15% (assuming 100%
collection efficiency) from 16.85% fixed for FY 2018-19 i.e. reduction of 1.85% in
one year. This appears difficult to achieve.
3.22 Considering collection efficiency of 99%, the licensee would be required to bring
down the losses to 14.14% in FY 2019-20 and to 13.13% in FY 2021-22 with the
above stipulated AT&C loss trajectory. Assuming best case 100% collection
efficiency, the licensee would have to bring down the losses to 14% in FY 2021-
22 from 17.64% in FY 2017-18.
3.23 The Petitioner is to complete the SAUBHAGYA household electrification target by
December 2018. Considering the increase in consumption of LT sales due to
SAUBHAGYA implementation, the Petitionerrequests the Hon’ble Commission to
revisit its plan to approve AT&C loss target of 14% by FY 2021-22. The sudden
increase in LT sales due to increased rural electrification has resulted in
increased distribution losses in H1 of FY 2018-19 vis-à-vis FY 2017-18 actual
distribution loss. The increased rural electrification will make it more difficult to
attain the loss targets stipulated by the Commission. Infact, the distribution loss
during FY 2018-19 (annual) is likely to be more than the FY 2017-18 loss figure.
Accordingly, the Petitioner requests the Commission to approve distribution loss
of 18.34% for FY 2018-19 and further reduction of 0.5% each year during the
control period from FY 2019-20 to FY 2021-22.
3.24 The Petitionerrequests to approve the distribution loss trajectory for the control
period from FY 2019-20 to FY 2021-22 as shown in the following table:

Energy Requirement
3.25 Based on the energy sales as estimated above along with the proposed
distribution loss trajectory, the energy requirement for the control period from
FY 2019-20 to FY 2021-22 has been estimated as below. The intra-state (AEGCL)
transmission loss of 3.44% has been considered as approved for FY 2018-19 in
the latest tariff order of AEGCL dated March 19’ 2018. The latest weighted
average 52-week transmission loss of NER and ER regions has been considered
as 1.55% for the control period from FY 2019-20 to FY 2021-22.
