(Ref: No. PNGRB/M(C)/17-Vol III dated 03.02.2016)
Subject: Final initial unit natural gas pipeline tariff under the
provisions of the Petroleum and Natural Gas
Regulatory Board (Determination of Natural Gas
Pipeline Tariff) Regulations, 2008.
Name of Entity: GAIL (India) Limited [GAIL]
Name of Pipeline: Dadri-Bawana-Nangal Natural Gas Pipeline Network
[2]
1. Regulatory Framework
1.1. In terms of Section 22 of the PNGRB Act, 2006, the Board is entrusted
with the responsibility of determining the natural gas pipeline tariff to be
charged by the entities laying, building, operating or expanding a natural
gas pipeline before the appointed day.
1.2. The methodology for determination of pipeline tariff has been specified in
the relevant provisions of the Petroleum and Natural Gas Regulatory Board
(Determination of Natural Gas Pipeline Tariff) Regulations, 2008
(hereinafter referred to as “Tariff Regulations”) notified on 20.11.2008.
Under the provisions of these regulations, PNGRB is to determine the
initial unit natural gas pipeline tariff on a provisional basis first and then
finalize the same considering the actual costs and data at the end of the
financial year on the basis of audited accounts. The transportation tariff is
determined using the Discounted Cash Flow (DCF) method using actual
and projected pipeline capex and opex costs (in line with provisions of
Tariff Regulations) over the entire economic life (25 years) of the pipeline
thus arriving at a single levelized transportation tariff. If the length of the
pipeline is more than 300 kms the recovery of the transportation tariff is
apportioned across such zones of 300 kms each resulting in zonal tariff
where the zonal tariff of a later zone is higher than that of an earlier zone.
2. Provisional Transportation Tariff Order
2.1. PNGRB issued the final terms and conditions of acceptance to Central
Government Authorization for Dadri-Bawana-Nangal Natural Gas Pipeline
Network (DBNPL) of GAIL vide communication dated 13.02.2011. The
[3]
provisional capacity and length as per the acceptance letter is 31
MMSCMD (including common carrier capacity of 7.75 MMSCMD) and
886 kms respectively.
2.2. PNGRB issued a provisional tariff order no. TO/07/2012 dated 12.07.2012
determining the provisional initial unit natural gas pipeline tariff under the
provisions of the Tariff Regulations for DBNPL of GAIL. (The same is
available on the PNGRB’s website.) The provisional transportation tariff as
proposed by GAIL and as determined by PNGRB are as follows:

2.3. As stated in the final terms and conditions of acceptance to Central
Government Authorization issued by PNGRB, the total length of the
network is 886 kms. Of this, the length of the trunk line and spur line is 336
km and 550 km respectively. Since the length of the trunk line is more than
300kms, there are two zones in the network.
2.4. PNGRB issued tariff order no. TO/01/2013 dated 18.02.2013 determining
the zonal tariff apportionment of the provisional initial unit natural gas
pipeline tariff under the provisions of the Tariff Regulations for DBNPL of
GAIL. (The same is available on the PNGRB’s website.) Accordingly,
based on the methodology for calculating the zonal tariffs as specified in
[4]
the Tariff Regulations, the zonal apportionment of provisional tariff
proposed by GAIL and that approved by PNGRB is as below.

3. Details of the Order of Appellate Tribunal for Electricity (APTEL)
3.1. GAIL had challenged PNGRB’s provisional tariff order in APTEL in
appeal no. 38 of 2014 on various aspects of computation of tariff. APTEL
in its order dated 29.05.2015 (in appeal no. 161/13 & batch) has held that
the provisional tariff already fixed shall continue to apply, subject to
adjustment, if any, in terms of the Regulations. APTEL directed PNGRB to
complete the process of determination of final tariff of DBNPL by
31.03.2016 and pass a speaking and reasoned order. APTEL also directed
PNGRB to consider the matter independently without being influenced by
the view already taken by it in the provisional tariff order. However, if after
independently considering the matter, PNGRB takes a view similar to the
one taken in the provisional tariff order, then this would not be held against
PNGRB.
3.2. GAIL was also directed by APTEL to make submissions including
challenges against the findings/observations/conclusions/calculations in the
provisional tariff orders. The last date to make these submissions in writing
[5]
before the Board was 30.07.2015. GAIL, vide its letters dated 27.07.2015
and 29.07.2015, has made common submissions for all 6 pipelines
networks whose provisional orders were challenged in APTEL. GAIL’s
submissions are placed as Annexure-1 and Annexure-2 and the relevant
issues are discussed under para 5 of this Public Consultation Document
(PCD).
3.3. GAIL had submitted partial tariff filing vide its letters dated 20.02.2015,
26.02.2015 and 30.04.2015. PNGRB was directed to inform GAIL about
any pending data and information required within 15 days from the date of
the order of APTEL. In conformity with the Order, PNGRB issued a letter
to GAIL dated 10.06.2015. GAIL submitted its response vide its letter
dated 08.07.2015. On scrutiny of the information submitted by GAIL, it
was observed that GAIL has not submitted the complete information as
some clarifications were required or some information was missing. Hence,
PNGRB vide its letter dated 07.09.2015 sought clarifications from GAIL.
In response, GAIL has submitted details vide its letter dated 18.09.2015.
GAIL in its letter has stated that it has provided the information sought by
PNGRB in its letter dated 29.06.2015, thereby ensuring compliance to the
directives of APTEL. It may be clarified to GAIL that PNGRB is only
seeking clarifications or asking GAIL to complete it submission and is not
asking GAIL for any additional information. GAIL in its letter dated
18.09.2015 has submitted additional CA certificates and some of these do
not reconcile with CA certificates already submitted by GAIL.

**Un-escalated figures
1. Project Execution (PE) Capex
Under PE head, GAIL has claimed a total future capex of Rs. 53.35
crores in the tariff filing. The amounts claimed in the tariff filing
has been escalated starting from the year 2014-15 and onwards at an
inflation rate of 5.87% per annum.
GAIL in its letter dated 08.07.2015 has claimed total PE capex of
Rs. 48.60 crores. This is comprised of LMC in Haridwar Region
[13]
(Rs. 1 crore) which GAIL has considered in the year 2014-15 and
LMC in NCR Region (Rs. 6 crores) and LMC for Rajpura
Consumers (Rs. 41.60 crores). In the tariff filing, GAIL has
considered LMC in NCR Region (Rs. 6 crores) and LMC for
Rajpura Consumers (Rs. 41.60 crores) after escalating it by 5.87%
per annum resulting in a total amount of Rs. 53.35 crores.
2. O&M Capex
Under O&M head, GAIL has claimed a total future capex of Rs.
361.61 crores.
GAIL in its letter dated 30.04.2015 claimed Rs. 166.75 crores as
O&M capex which it revised to Rs. 167.75 crores vide its letter
dated 08.07.2015. GAIL has stated that this O&M capex amount is
suitably inflated in the model using appropriate inflation rate.
3. PD Capex
Under PD head, GAIL has claimed a total future capex of Rs.
891.35 crores. The projections are for future last mile connectivities
(LMC) in the pipeline. The LMC amount claimed in the tariff filing
is claimed under two heads: (i) PD future capex with IDC
(amounting to Rs. 423.25 crores) and (ii) PD future capex without
IDC but after inflation (amounting to Rs. 468.10 crores). GAIL has
considered inflation rate at a rate of 5.87% p.a. starting from the
year 2014-15 and onwards.
i. ‘PD future capex with IDC’ (amounting to Rs. 423.25 crores)
– This amount includes IDC of Rs. 32.99 crores from 2015-16
[14]
to 2017-18 and it also considers escalation at 5.87% p.a. from
2014-15 and onwards. However, GAIL in its submissions vide
letters dated 30.04.2015 and 08.07.2015 has not considered
IDC value in these figures. Hence the total PD figures do not
reconcile.
ii. ‘PD future capex without IDC but after inflation’ (amounting
to Rs. 468.10 crores) includes Rs. 105.94 crores in 2015-16
and Rs. 10 crores per annum from 2016-17 to 2034-35 (All
these figures are escalated by 5.87% per annum from 2014-15
and onwards). To substantiate this claim, GAIL vide it letter
dated 08.07.2015 has submitted CA certificate for addition to
last mile connectivity from 2011-12 to 2014-15 stating that the
total capitalization cost during this period is Rs. 427.59 crore.
Hence GAIL has stated that it has incurred average
expenditure of Rs. 106.90 crores per year. Hence, GAIL has
stated that presently minimal future capex of Rs. 10 crores /
year has been considered to provide LMC to new customers
enroute DBNPL network from 2015-16 onwards which is
much lower than the actual yearly capital investment done
during the last four years.
GAIL’s comments on future capex is mentioned as point 4 from page
(32) to (35) of annexure A of GAIL’s letter dated 27.07.2015 annexed
to this PCD.
[15]
c) Actual Common Corporate Assets from 2008-09 to 2014-15
In the tariff filing, GAIL has claimed actual common corporate assets
from 2008-09 to 2014-15 of Rs. 3.92 crores. GAIL has submitted
first CA certificate dated 18.06.2015 vide letter dated 23.06.2015
providing allocation of assets from 2009-10 to 2013-14. Subsequently
GAIL submitted second CA certificate dated 16.09.2015 vide its letter
dated 18.09.2015 providing allocation of assets in 2014-15.Year-wise
gross common corporate assets allocated to DBNPL as given in the
tariff filing and that certified in CA certificates submitted by GAIL is

[16]
With regards to mechanism for allocation of common corporate assets
GAIL has stated that - GAIL has 8 offices/work centers and 11 zonal
marketing offices providing services to the whole company. There are
many capital expenditure and operating expenditure incurred to build,
maintain and operate these offices. GAIL has calculated the total
capex and opex of these offices and bifurcated them among all
business segments of the company on the basis of total gross block of
respective business segments. Capex and opex allocated to business
segment – NG Transmission is then allocated to all the pipelines
including dedicated pipelines on the basis of actual throughput in that
particular pipeline system in the corresponding previous year.
PNGRB in its letter dated 07.09.2015 sought clarifications on the
allocation of corporate common assets that GAIL had submitted on
23.06.2015. It was also observed that GAIL had included marketing
related assets in the common corporate assets and has allocated it to
NG transmission business which is not in line with PNGRB
Regulations. GAIL was asked: (a) rationale of allocation of the assets
to all business segments on the basis of gross block, (b) bifurcation of
these assets (excluding all marketing and finance related assets) into
direct and indirect assets certified by CA, (c) reconciliation of indirect
assets (excluding all marketing and finance related assets) with un-
allocable assets appearing in the business segment information in
annual report of GAIL certified by CA.
GAIL in its response to the clarifications sought by PNGRB reiterated
the same rationale allocation for common corporate assets and has not
[17]
submitted the bifurcation into direct and indirect assets and
reconciliation of indirect assets with un-allocable assets. GAIL also
stated that as corporate marketing department is providing services to
Gas Transmission and all other business segments also, therefore all
common assets including marketing related expenses are allocated to
all business segments.
d) Future common corporate assets projections from 2015-16 to 2034-35
GAIL, in its tariff filing, has not claimed any future common
corporate assets from 2015-16 to 2034-35.
5.4. Operating Expenses (Opex)
Head-wise breakup of opex considered by GAIL in its tariff submission for
the entire economic life of the pipeline as follows:
(Amount Rs. in crores)
Particulars
a) Opex outgo (2009-10 to 2014-15) 123.53
b) Future opex projections (2015-16 to 2034-35) 3050.24
c) Common corporate expenses (2009-10 to 2014-15) 7.55
d) Future common corporate expenses (2015-16 to 2034-35) 3.91
TOTAL 3185.23
a) Actual Opex Outgo from 2009-10 to 2014-15
In its tariff filing, GAIL has claimed opex of Rs. 123.53 crores from
2009-10 to 2014-15. Year-wise breakup of opex claimed in tariff
filing (excluding common corporate expenses) and that certified in CA
certificate submitted by GAIL is as follows:

TOTAL 123.53 9.53
* Includes Interest Apportionment of Rs. 2.78 cr
** This is projected figure in the tariff filing
The following points are observed:
i. GAIL in its letter dated 30.04.2015 has stated that as the
pipeline was commissioned on 06.01.2010 and opex has been
allocated based on last year volume flow, therefore no opex
for the period from 01.01.2010 to 31.03.2010 has been
allocated.
ii. GAIL has not netted off miscellaneous income from operating
expenses in tariff filling as well as in CA certificate.
iii. Further, the total opex figures for DBNPL from 2008-09 to
2013-14 certified in the CA certificate could not be reconciled
with the trial balances of GAIL due to the discrepancies
mentioned in para 5.2 above.
[19]
GAIL’s comments on netting off misc. income is mentioned as point 7
on page (37) of annexure A of GAIL’s letter dated 27.07.2015
annexed to this PCD
b) Future opex projections from 2015-16 to 2034-35
In its tariff filing, GAIL has claimed a future capex of Rs. 3050.24
crores from 2015-16 to 2034-35. This amount includes:
i. O&M escalated future opex of Rs. 384.38 crores
ii. PE future opex of Rs. 54.24 crores
iii. PD future opex of Rs. 305.15 crores
iv. Other opex of Rs. 2306.47 crores
GAIL has considered annual escalation rate of 5.87% p.a. from 2014-
15 onwards and has considered 280 operating days in the year 2034-
35.
GAIL’s comments on inflation rate is mentioned as point 3 from page

c) Actual common corporate expenses from 2009-10 to 2014-15
[20]
Actual expenses claimed by GAIL during this period are Rs. 7.55
crores. Year-wise breakup of expenses claimed in tariff filing and that
certified in CA certificates submitted by GAIL is tabulated in table
below. GAIL has submitted two CA certificates on the bifurcation of
common corporate expenses amongst all natural gas pipelines.
However the figures in these two CA certificates do not reconcile.

Rationale for allocation of the actual expenses: With regards to
mechanism for allocation of common corporate expenses GAIL has
stated that it has 8 offices/work centres and 11 zonal marketing offices
providing services to the whole company. There are many capital
[21]
expenditure and operating expenditure incurred to build, maintain and
operate these offices. GAIL has calculated the total capex and opex of
these offices and bifurcated them among all business segments of the
company on the basis of total gross block of respective business
segments. Capex and opex allocated to business segment – NG
Transmission is then allocated to all the pipelines including dedicated
pipelines on the basis of actual throughput in that particular pipeline
system in the corresponding previous year.
PNGRB in its letter dated 07.09.2015 sought clarifications on the
allocation of corporate common expenses that GAIL had submitted on
23.06.2015. It was also observed that GAIL had included marketing
related expenses in the common corporate expenditure and has
allocated it to NG transmission business which is not in line with
PNGRB Regulations. GAIL was asked: (a) rationale of allocation of
the expenses to all business segments on the basis of gross block, (b)
bifurcation of these expenses (excluding all marketing and finance
related expenses) into direct and indirect expenses certified by CA, (c)
reconciliation of indirect expenses (excluding all marketing and
finance related expenses) with un-allocable expenses appearing in the
business segment information in annual report of GAIL certified by
CA.
GAIL in its response to the clarifications sought by PNGRB reiterated
the same rationale allocation for common corporate expenses and has
not submitted the bifurcation into direct and indirect expenses and
reconciliation of indirect expenses with un-allocable expenses. GAIL
[22]
also stated that as corporate marketing department is providing
services to Gas Transmission and all other business segments also,
therefore all common expenses including marketing related expenses
are allocated to all business segments.
d) Future common corporate expenses from 2015-16 to 2034-35
In addition to the above, GAIL has also claimed future common
corporate expenses of Rs. 3.91 crores. Expenses claimed in each year
are calculated by considering 2.5% of the sum of total capex outgo
from 2008-09 to that respective year. Each year’s figure is then
escalated by 5.87% annually, starting from 2014-15 onwards. GAIL
has considered 280 operating days in the year 2034-35.
5.5. Unaccounted Gas
In addition to the opex, GAIL has considered 0.3% of the throughput as
unaccounted gas loss, as a cost to be recovered through the transportation
tariff. GAIL, in its tariff filing, has claimed a total unaccounted gas loss of
Rs. 2492.06 crores from 2008-09 to 2034-35.
Further, PNGRB vide its letters dated 26.05.2015 and 10.06.2015 had
asked GAIL to provide CA certificate for unaccounted gas data in
MMSCM and unaccounted gas expenditure from 2008-09 onwards as
appearing in the books of accounts for both sub-networks of DBNPL.
GAIL vide its letter dated 08.07.2015 has submitted a CA certificate on
unaccounted gas loss from 2008-09 to 2014-15 as appearing in the audited
books of accounts of GAIL. This is tabulated below along with figures in
tariff filing for the same period.

2014-15 51.80 4.83
TOTAL 158.37 10.29
In addition to the figures mentioned in the table above, GAIL has claimed
projected future unaccounted gas of Rs. 2333.69 crores from 2015-16 to
2034-35.
GAIL’s comments on unaccounted gas loss is mentioned as point 2 from
page (29) to (31) of annexure A of GAIL’s letter dated 27.07.2015 annexed
to this PCD.
5.6. Volume Divisor
As per the final terms and conditions of acceptance to Central Government
Authorization issued by PNGRB the total capacity is 31 MMSCMD
(including common carrier capacity of 7.75 MMSCMD).
Year-wise capacity considered by GAIL in its tariff submission is as
follows:
[24]
(In MMSCMD)
Year Capacity
2009-10 2.89
2010-11 3.01
2011-12 4.83
2012-13 8.59
2013-14 11.57
2014-15 12.00
2015-16 12.89
2016-17 13.77
2017-18 12.03
2018-19 onwards 12.07
GAIL’s comment on volume divisor is mentioned as point 2 from page
(19) to (28) of annexure A of GAIL’s letter dated 27.07.2015 annexed to
this PCD.
5.7. Working Capital
Working capital is calculated as sum of 30 days of opex (excluding
depreciation) and 18 days of revenue (tariff receivables), in conformity
with the Tariff Regulations. GAIL, in its tariff submission, has considered
total working capital of Rs. 71.41 crores for DBNPL.
[25]
5.8. Number of Working Days
As per the Clause 14(3) of the Access Code Regulations, the planned
maintenance period shall not exceed 10 days in a year. On this basis, there
would be 355 working days for a pipeline in one financial year. GAIL has
considered 85 operating days for the year 2009-10, 345 operating days for
all years from 2010-11to 2033-34 and 280 operating days in 2034-35.
GAIL’s comment on number of working days in a year is mentioned as
point 5 from page (35) to (36) of annexure A of GAIL’s letter dated
27.07.2015 annexed to this PCD.
5.9. Line Pack
Line pack is the value of gas which always remains in the pipeline and as
per regulations it is to be considered as cash outflow in the initial year and
to be considered as cash inflow in the last year of the economic life of the
pipeline.
GAIL, in its tariff model, has considered line pack of Rs. 9.20 crores in
2009-10 (phase 1) and Rs. 47.25 crores in 2012-13 (phase 2).
5.10. Terminal Value
Terminal Value is the sum of the residual value of the assets at the end of
the economic life, working capital and line pack. It is considered as cash
inflow at the end of economic life of the pipeline.
The terminal value submitted by GAIL in its tariff filing is Rs. 1729.64
crores as on 31.03.2035.
[26]
5.11. Return on Capital Employed
GAIL has computed the annual rate of return using a rate of return of 12%
and further grossing this up with the rates of corporate income tax
applicable to each year. For this purpose, GAIL has considered year-wise
income tax rates for both sub-networks as follows:
Year FY 08-
09
FY 09-
10
FY 10-
11
FY 11-
12
FY 12-
13
FY 13-14
and
beyond
Income
Tax
Rate
33.99% 33.99% 33.22% 32.45% 32.45% 33.99%
So in order to arrive at a post tax rate of return of 12% for each year of the
pipeline project, this translates to an allowable pre-tax rate of return, as
claimed in the tariff filing, as follows:
Year FY 08-
09
FY 09-
10
FY 10-
11
FY 11-
12
FY 12-
13
FY 13-14
and
beyond
Rate of
return 18.18% 18.18% 17.97% 17.76% 17.76% 18.18%
Clause 2 of Schedule A of the Tariff Regulations mandates that natural gas
pipeline tariff shall be calculated based on the DCF methodology after
considering the reasonable rate of return (i.e. “twelve percent post tax” as
per clause 3 to Schedule A) to be the projects internal rate of return.
[27]
5.12. Zonal Apportionment
As discussed in para 2.3 above, DBNPL has two zones. Further, as stated
by GAIL vide its letter dated 30.04.2015, increment of zone 2 tariff over
zone 1 tariff is 0.1%.
5.13. Other Issues
In addition to comments on some of the issues stated above, GAIL in its
letters dated 27.07.2015 and 29.07.2015 has provided comments on the
issues:
(a) Interest During Construction - mentioned as point 6 on page (36)
of annexure A of GAIL’s letter dated 27.07.2015 annexed to this
PCD.
