Executive Summary
1.0 INTRODUCTION
1.1 India is deficit in Liquefied Petroleum Gas (LPG). Industry imports LPG to the tune of
5 MMTPA to meet the domestic demand. South India, comprising Andhra Pradesh
(A.P.), Karnataka, Kerala and Tamil Nadu, is also deficit in LPG.
1.2 In 2010-11 and 2011-12, the deficit of LPG in southern region was about 2.8 MMTPA
and 3.0 MMTPA respectively. As per the latest supply-demand assessment, the demand
in south India is expected to be about 6.4 MMTPA in 2016-17 and about 7.3 MMTPA
by 2021-22. Domestic availability of LPG would be about 4.3 MMTPA and
4.5 MMTPA in those years. The deficit in 2016-17 is projected to reduce from the
present level of 3.0 MMTPA to 2.1 MMTPA, mainly due to additional production of
LPG after implementation of the proposed expansion plans at Chennai refinery of
Chennai Petroleum Corporation Limited (CPCL), Kochi refinery, Mangalore refinery
and Vizag refinery, and commissioning of Nagarjuna refinery. However, the deficit is
projected to increase again to 2.8 MMTPA in 2021-22, which would continue. This
deficit would be met by import of LPG through coastal receipts at Ennore, Vizag,
Mangalore and Kochi ports.
1.3 Presently, IOC operates 11 LPG bottling plants in Tamil Nadu viz. Ennore, Erode,
Ilayangudi, Madurai, Mannargudi, Mayiladuthurai, Salem, Trichy, Chengalpet,
Coimbatore and CPCL Chennai and 1 plant at Pondicherry.
1.4 M/s IndianOil Petronas Private Ltd. (IPPL), a Joint Venture of IOC and Petronas,
Malaysia have set up a LPG import terminal at Ennore, primarily to meet the deficit of
LPG in Tamil Nadu. The terminal has been commissioned and is in operation since
August 2012, handling about 100 TMT of LPG per month. It presently supplies LPG to
IOCs bottling plants at Ennore, Ilayangudi, Trichy and Madurai in Tamil Nadu by road
tankers.
1.5 CPCL has monthly output of about 33 TMT of LPG, out of which IOCs share is about
28 TMT. This LPG is predominantly used for meeting non-domestic requirement of all
bottling plants in Tamil Nadu, Cuddapah bottling plant in A.P. and about 50%
requirement of Devanagonthi bottling plant in Karnataka. Requirement of CPCLs
Executive SummaryEnnore-Trichy-Madurai LPG Pipeline ( ii )
bottling plant at Chennai is also met by CPCL refinery. Requirement of domestic LPG
in Tamil Nadu, Cuddapah and part requirement of Devanagonthi is met from LPG
import terminal at Ennore by road tankers.
1.6 As these bottling plants are situated at considerable distance from Ennore, an
optimisation study was carried out in 2011, which indicated that there would be
considerable savings if a LPG pipeline system was put in place from Ennore to Trichy
via Chengalpet and Pondicherry to substitute the road movement of LPG ex-
Chennai/Ennore to the bottling plants in Tamil Nadu and Pondicherry. Further, nodal
movement from Trichy was envisaged to reduce road movement to other bottling plants
in Tamil Nadu. LPG sourcing for bottling plants in other states of south India would
continue from the existing sources at Ennore, Mangalore, Vizag and the proposed
import terminal at Kochi.
1.7 Vide Agenda Item No. P/224 dated 23.4.2012, Board had accorded first-stage approval
to the proposal of laying a pipeline from Ennore to Trichy for transportation of LPG and
had approved an amount of Rs.5 crore for carrying out pre-project activities, so as to
facilitate preparation of Detailed Feasibility Report (DFR) for the proposal. The Board
had also advised to carry out study of various alternatives of pipeline connectivity to
more bottling plants in Tamil Nadu.
1.8 Subsequent to the first-stage approval, survey of the pipeline route has been completed
and optimisation has been carried out for different pipeline configurations so as to arrive
at the optimum configuration. Details are as under.
1.9 Analysis of Alternatives
1.9.1 To start with, assumptions considered for optimization study carried out in April 2011
for formulation of feasibility report (FR) were revisited. It emerged that, with
materialization of Kochi LPG terminal proposal, which was not considered at the time
of preparation of FR, there might be some impact on the throughput of the proposed
pipeline. Accordingly, optimization study was carried out again in September 2012,
considering LPG import facilities to be available at Kochi by 2016-17. The proposal for
Kochi LPG import terminal was subsequently approved by the Board in
December 2012.

From the above details, it emerged that throughput of the pipeline would remain the
same in any combination of linked bottling plants.
1.9.3 Preliminary analysis of various alternatives was then carried out and the two best
options were short-listed for preparation of the detailed scheme and cost estimates,
manpower assessment and financial analysis etc. Results of the analysis were as under.

1.9.4 This study concluded that Ennore-Trichy pipeline and Ennore-Trichy-Madurai pipeline
would be the two financially most attractive pipeline configurations.
1.9.5 Based on the above analysis, CO(Optimisation) undertook another study in January
2013, considering updated demand numbers for working out throughput and savings for
the said two pipeline configurations. The study considered all-India supply-demand
scenario for IOC in 2016-17 and 2021-22. Findings of the study were as under.

Ennore-Trichy-Madurai Pipeline 617 809 103.5 169.9
It can be noted that throughput projection and savings for both 2016-17 and 2021-22
have improved from earlier workings in both pipeline configurations.
1.9.6 IOC already has a petroleum product pipeline from Chennai to Madurai due to which
right-of-way (RoW) up to Madurai is already available. Therefore, considering
availability of most of the right-of-way up to Madurai and marginal difference in RoI
for pipeline up to Trichy vis--vis pipeline up to Madurai, it was considered prudent to
undertake detailed feasibility study for laying the pipeline up to Madurai. The DFR has
been prepared accordingly.
1.10 The DFR broadly deals with the need and justification, system configuration, cost,
viability, implementation methodology and allied details in respect of the proposed
pipeline from Ennore to Madurai via Trichy. The pipeline would originate at Ennore
import terminal and terminate at the existing Madurai bottling plant, providing pipeline
connectivity en route to the existing LPG bottling plants at Chengalpet, Pondicherry and
Trichy.
2.0 NEED AND JUSTIFICATION
2.1 The demand of LPG in south India in 2011-12 was about 4.5 MMTPA. As per the latest
LPG supply-demand workings by Marketing Division, LPG demand of Industry for
south India is projected as under.
Fig. in MMT
Year 2016-17 2018-19 2021-22
South India Demand 6.4 6.8 7.3
2.2 Considering actual demand of previous year, projected growth rate in the demand and
supply scenario, CO(Optimisation) has carried out optimization study for proposed
Ennore-Trichy-Madurai LPG pipeline for 2016-17 and 2021-22. The study projects
throughput of 617 TMT in 2016-17 and 809 TMT in 2011 for the pipeline and
substantial savings in logistics cost.
Executive SummaryEnnore-Trichy-Madurai LPG Pipeline ( v )
2.3 At present, CPCL refinery is producing about 33 TMT of LPG per month. CPCLs LPG
is primarily used for bottling plant at Chennai, non-domestic requirement of bottling
plants in Tamil Nadu, Cuddapah in A.P. and partial requirement of Devanagonthi
bottling plants.
2.4 Most of domestic requirement of LPG at IOCs bottling plants in Tamil Nadu,
Cuddapah in A.P. and partial requirement of Devanagonthi is met from LPG import
terminal at Ennore by Road Tankers.
2.6 Throughput Projections
2.6.1 The supply and distribution plans of LPG for various bottling plants linked to the
proposed pipeline, for 2016-17 and 2021-22, have been projected to be as under.

2.6.2 It may be seen from the above table that out of the projected throughput of 617 TMT for
2016-17, about 134 TMT and 24 TMT of LPG would be transported through road from
Trichy and Madurai respectively. Similarly, out of the projected throughput of 809 TMT
Executive SummaryEnnore-Trichy-Madurai LPG Pipeline ( vi )
for 2021-22, about 235 TMT and 50 TMT of LPG would be transported through road
from Trichy and Madurai respectively.
2.7 The long-term projected throughput for the pipeline would be as under. For working out
projected demand beyond 2021-22, growth rate of 1.76% has been considered, as
assessed by the Planning Cell of Marketing Division. As the pipeline would originate
from Ennore import terminal, the additional demand would be met by increasing the
imports.
Throughput Projections (TMT)
2016-17 2021-22 2026-27
617 809 883
2.8 It is pertinent to mention here that while some of the bottling plant capacities are
projected to be saturated during 2016-17, the demand in attached markets would
continue to increase. Therefore, it would be required to either stretch the capacities of
the existing plants or set up new bottling plants in and around the existing markets to
meet the increased LPG demand as required. Therefore, the pipeline facilities have been
designed considering long-term demand projections.
2.9 For facilitating nodal movement to linked bottling plants from Trichy and Madurai, the
existing unloading bays would be converted to loading bays.
2.10 The transportation requirement of LPG volumes indicated in para 2.7 can be met by the
following alternative modes.
a) By Road
b) By Pipeline
Railway has not been considered as a feasible transportation option for LPG as the
existing bottling plants do not have rail linkage.
2.11 It has been established the world over that pipelines are superior means for
transportation of petroleum products compared to other modes viz. rail, road, tankers
etc. due to their inherent advantages like reliability, economy, safety, flexibility, low
energy consumption, low transit losses and negligible impact on environment.
Construction of new pipelines provides relief to other modes of transportation for
movement of essential commodities and passengers.
Executive SummaryEnnore-Trichy-Madurai LPG Pipeline ( vii )
2.12 In view of the above, it is proposed to lay Ennore-Trichy-Madurai LPG pipeline for
transportation of LPG from Ennore to the LPG bottling plants at Chengalpet,
Pondicherry, Trichy and Madurai. The proposed pipeline would realign movement of
LPG for certain other bottling plants viz. Salem, Coimbatore, Erode, Ilayangudi and
Tirunalveli from Trichy and Madurai in place of the present practice of movement from
Ennore. Thus, the proposed pipeline would considerably reduce distances involved in
road movements and thereby, logistics cost.
3.0 Design Capacity
3.1 Taking into account findings of the optimization study and the requirements of linked
bottling plants, it is proposed to design the proposed LPG pipeline from Ennore to
Madurai for a capacity of 0.9 MMTPA.
4.0 Project Description
4.1 Pipeline Route
4.1.1 The proposed pipeline would originate at IPPLs LPG import facilities at Ennore and
would follow an independent route for approximately 30 km, where it would meet the
existing right-of-way (RoW) of Chennai-Trichy-Madurai Pipeline (CTMPL) at its
chainage 27.4 km. Thereafter, the pipeline would follow the RoW of CTMPL up to
Madurai via Asanur except for about 5.3 km detour for linking Chengalpet bottling
plant, about 55 km to Pondicherry bottling plant and about 19 km to Trichy. The
pipeline, after leaving CTMPL RoW near Madurai delivery station of CTMPL, would
further follow an independent route for about 28 km to reach the bottling plant at
Madurai.
4.2 System Configuration
4.2.1 Configuration of the pipeline system broadly comprises the following.
Total length: 615 km
419 km long, 10.75 OD x 0.25 WT pipeline section from Ennore to T-Point
location for Trichy bottling plant
55 km long, 8.625 OD x 0.25 WT branch pipeline from T-point to
Pondicherry and 19 km long, 8.625 OD x 0.25 WT branch pipeline from T-
point to Trichy
Executive SummaryEnnore-Trichy-Madurai LPG Pipeline ( viii )
122 km long, 8.625 OD x 0.25 WT, branch pipeline from T-point location

4.3 Operation Philosophy
4.3.1 Operation of the pipeline would predominantly be through heart-cut mode.
4.4 Implementation Methodology
4.4.1 It is proposed to take up execution of the project through in-house expertise.
4.5 Statutory Clearances
4.5.1 Suitable actions will be taken for obtaining MoE&F clearance and other statutory
clearances for the proposed pipeline from concerned authorities, as applicable.
4.6 Construction Schedule
4.6.1 The proposed scheme is expected to be completed in a period of about 30 months after
receipt of statutory clearances.
4.7 Manpower Requirement
4.7.1 The manpower requirement would be about 82 during construction phase and about 76
for operation of the pipeline, excluding Line Patrolmen (LPM). The requirement of
LPM for the new portion of right-of-way is envisaged to be outsourced.
5.0 Capital Cost
5.1 The pipeline system from Ennore to Madurai is estimated to cost Rs.711 crore,
including a foreign exchange component of Rs.202 crore, at December 2012 price level.
This includes Rs.60 lakh required for modifications in unloading bays at Trichy and
Madurai bottling plants for their use as loading bays.
5.2 The cost estimates have been prepared on conservative basis without considering
benefits under EPCG (Export Promotion Capital Goods) scheme.
6.0 Operating Cost
6.1 Operating cost of the pipeline system includes the cost of power for mainline pumping
units, utilities, consumables, salaries and wages, administrative overheads, repair and
Executive SummaryEnnore-Trichy-Madurai LPG Pipeline ( ix )
maintenance etc. The operating cost corresponding to throughput of 0.9 MMTPA is
estimated to be about Rs.30 crore per annum at December 2012 price level.
7.0 Financial Analysis
7.1 Capital cost of the project is considered to be financed through internal
resources/commercial borrowings. For the purpose of financial analysis, debt:equity
ratio of 1:1 has been considered, with interest @ 10.75% per annum and repayment in 8
equal annual installments, with one-year moratorium from the date of commissioning.
Requirement of working capital will be met through internal resources.
7.2 Financial analysis for the proposed pipeline system has been carried out taking into
account the following.
Capital cost of the pipeline and its operation for 15 years / 25 years
Throughput as indicated in the optimization study for 2016-17 and 2021-22

8.0 Conclusions and Recommendations
8.1 Most of the LPG bottling plants in Tamil Nadu are situated at considerable distance
from Ennore. Optimization study indicates that there would be considerable savings by
laying a LPG pipeline from Ennore to Madurai via Chengalpet, Pondicherry and Trichy,
which would substitute road movement of LPG ex-Ennore to these bottling plants.
8.2 Results of the financial analysis indicate that the proposed pipeline is viable under most
of the scenarios considering the prevailing hurdle rate of 13%. The pipeline will
facilitate cost-effective transportation of LPG from Ennore to different bottling plants in
Tamil Nadu and one plant at Pondicherry.
8.3 IOC intends to lay several LPG pipelines to provide connectivity to its major LPG
bottling plants. With commissioning of LPG import terminal at Ennore and
implementation of Kochi terminal, potential exists to lay new LPG pipelines from these
two sources and formation of a LPG grid in south India in future. It would, therefore, be
prudent to lay the proposed Ennore-Trichy-Madurai LPG pipeline for providing pipeline
connectivity to all major bottling plants en route. Providing pipeline connectivity to
other major bottling plants in Tamil Nadu viz. Coimbatore, Salem and Erode could be
examined at a later stage.
8.4 Keeping the above in view, it is recommended to lay Ennore-Trichy-Madurai LPG
pipeline at an estimated cost of Rs.711 crore, including a foreign exchange component
of Rs.202 crore, at December 2012 price level. This includes cost of modifications in
Marketing facilities at Trichy and Madurai at an estimated cost of Rs.60 lakh.

CHAPTER I
1.0 INTRODUCTION
1.1 India is deficit in Liquefied Petroleum Gas (LPG). Industry imports LPG to the tune of
5 MMTPA to meet the domestic demand. South India, comprising Andhra Pradesh
(A.P.), Karnataka, Kerala and Tamil Nadu, is also deficit in LPG.
1.2 In 2010-11 and 2011-12, the deficit of LPG in southern region was about 2.8 MMTPA
and 3.0 MMTPA respectively. As per the latest supply-demand assessment, the
demand in south India is expected to be about 6.4 MMTPA in 2016-17 and about
7.3 MMTPA by 2021-22. Domestic availability of LPG would be about 4.3 MMTPA
and 4.5 MMTPA in those years. The deficit in 2016-17 is projected to reduce from the
present level of 3.0 MMTPA to 2.1 MMTPA, mainly due to additional production of
LPG after implementation of the proposed expansion plans at Chennai refinery of
Chennai Petroleum Corporation Limited (CPCL), Kochi refinery, Mangalore refinery
and Vizag refinery, and commissioning of Nagarjuna refinery. However, the deficit is
projected to increase again to 2.8 MMTPA in 2021-22, which would continue. This
deficit would be met by import of LPG through coastal receipts at Ennore, Vizag,
Mangalore and Kochi ports.
1.3 Presently, IOC operates 11 LPG bottling plants in Tamil Nadu viz. Ennore, Erode,
Ilayangudi, Madurai, Mannargudi, Mayiladuthurai, Salem, Trichy, Chengalpet,
Coimbatore and CPCL Chennai and 1 plant at Pondicherry.
1.4 M/s IndianOil Petronas Private Ltd. (IPPL), a Joint Venture of IOC and Petronas,
Malaysia have set up a LPG import terminal at Ennore, primarily to meet the deficit of
LPG in Tamil Nadu. The terminal has been commissioned and is in operation since
August 2012, handling about 100 TMT of LPG per month. It presently supplies LPG
to IOCs bottling plants at Ennore, Ilayangudi, Trichy and Madurai in Tamil Nadu by
road tankers.
1.5 CPCL has monthly output of about 33 TMT of LPG, out of which IOCs share is about
28 TMT. This LPG is predominantly used for meeting non-domestic requirement of all
bottling plants in Tamil Nadu, Cuddapah bottling plant in A.P. and about 50%
DFR Ennore-Trichy-Madurai LPG Pipeline Page 2 of 38
requirement of Devanagonthi bottling plant in Karnataka. Requirement of CPCLs
bottling plant at Chennai is also met by CPCL refinery. Requirement of domestic LPG
in Tamil Nadu, Cuddapah and part requirement of Devanagonthi is met from LPG
import terminal at Ennore by road tankers.
1.6 As these bottling plants are situated at considerable distance from Ennore, an
optimisation study was carried out in 2011, which indicated that there would be
considerable savings if a LPG pipeline system was put in place from Ennore to Trichy
via Chengalpet and Pondicherry to substitute the road movement of LPG ex-
Chennai/Ennore to the bottling plants in Tamil Nadu and Pondicherry. Further, nodal
movement from Trichy was envisaged to reduce road movement to other bottling
plants in Tamil Nadu. LPG sourcing for bottling plants in other states of south India
would continue from the existing sources at Ennore, Mangalore, Vizag and the
proposed import terminal at Kochi.
1.7 Vide Agenda Item No. P/224 dated 23.4.2012, Board had accorded first-stage approval
to the proposal of laying a pipeline from Ennore to Trichy for transportation of LPG
and had approved an amount of Rs.5 crore for carrying out pre-project activities, so as
to facilitate preparation of Detailed Feasibility Report (DFR) for the proposal. The
Board had also advised to carry out study of various alternatives of pipeline
connectivity to more bottling plants in Tamil Nadu.
1.8 Subsequent to the first-stage approval, survey of the pipeline route has been
completed. Based on the optimisation study for different pipeline configurations,
preliminary analysis of various alternatives was carried out and the two best options
were short-listed for preparation of the detailed scheme and cost estimates, manpower
assessment and financial analysis etc. This study concluded that Ennore-Trichy
pipeline and Ennore-Trichy-Madurai pipeline would be the two financially most
attractive pipeline configurations. The study has been covered in details in Chapter-II.
1.9 Based on the above analysis, CO(Optimisation) undertook another study in January
2013, considering updated demand numbers for working out throughput and savings
for the two pipeline configuration i.e. Ennore-Trichy pipeline and Ennore-Trichy-
Madurai pipeline. IOC already has a petroleum product pipeline from Chennai to
Madurai due to which right-of-way (RoW) up to Madurai is already available.
Therefore, considering availability of most of the right-of-way up to Madurai and
DFR Ennore-Trichy-Madurai LPG Pipeline Page 3 of 38
marginal difference in Return-on-Investment (RoI) for pipeline up to Trichy vis--vis
pipeline up to Madurai, it is considered prudent to undertake detailed feasibility study
including viability study for laying the pipeline up to Madurai. The DFR has been
prepared accordingly.
1.10 The DFR broadly deals with the need and justification, system configuration, cost,
viability, implementation methodology and allied details in respect of the proposed
pipeline from Ennore to Madurai via Trichy. The pipeline would originate at Ennore
import terminal and terminate at the existing Madurai bottling plant, providing pipeline
connectivity en route to the existing LPG bottling plants at Chengalpet, Pondicherry
and Trichy.

CHAPTER - II
2.0 ANALYSIS OF ALTERNATIVES
2.1 While analyzing the proposal seeking first-stage approval for Ennore-Trichy LPG
pipeline, a view emerged that options be explored for minimizing nodal movement
through road tankers and, instead, feeding additional bottling plants in the region
through the pipeline itself. Accordingly, a preliminary feasibility study was carried out
for linking the proposed Ennore-Trichy LPG pipeline with 6 major bottling plants in
Tamil Nadu viz. Chengalpet, Trichy, Madurai, Salem, Erode and Coimbatore and one at
Pondicherry. The study indicated that Ennore-Trichy pipeline configuration was
financially most attractive among various pipeline alternatives.
2.2 Accordingly, IOC Board accorded first-stage approval to the proposal of laying a
pipeline from Ennore up to Trichy for transportation of LPG and sanctioned an amount
of Rs.5 crore for carrying out pre-project activities, so as to facilitate preparation of
Detailed Feasibility Report (DFR) for the proposal. At the same time, Board also
advised to carry out study of various alternatives for connectivity of more bottling plants
in Tamil Nadu.
2.3 In the mean time, a proposal for LPG terminal at Kochi proposal was revived, and was
approved by the Board in December 2012. This development was a major change in the
basic premises considered for preparation of Ennore-Trichy LPG pipeline proposal, as
feasibility report of Ennore-Trichy pipeline was based on the optimization study
considering without LPG import facilities at Kochi. Approval of the proposed LPG
import facilities at Kochi mandated fresh optimization study for the proposed pipeline.
Accordingly, an optimization study was carried out in September 2012, considering
import facilities at Kochi functional by 2016-17.
2.4 Findings of the optimization study of September 2012 were as under.

2.6 This study concluded that Ennore-Trichy pipeline and Ennore-Trichy-Madurai pipeline
would be the two financially most attractive pipeline configurations.
2.7 Based on the above analysis, CO(Optimisation) undertook another study in January
2013, considering updated demand numbers for working out throughput and savings
for the said two pipeline configurations. Summary Report of this study is given in
Attachment 2.1.
2.8 Considering availability of most of the right-of-way up to Madurai and marginal
difference in return on investment (RoI) for pipeline up to Trichy vis--vis pipeline up to
Madurai, it was considered prudent to undertake proposal for laying the pipeline up to
Madurai.
2.9 Accordingly, the DFR has been prepared for 615 km long Ennore-Trichy-Madurai
LPG pipeline.

CHAPTER - III
3.0 NEED AND JUSTIFICATION
3.1 The demand of LPG in south India in 2011-12 was about 4.5 MMTPA. As per the
latest LPG supply-demand workings by Marketing Division, LPG demand of Industry
for south India is projected as under.
Fig. in MMT
Year 2016-17 2018-19 21-22
South India Demand 6.4 6.8 7.3
3.2 Considering actual demand of previous year, projected growth rate in the demand and
supply scenario, CO(Optimisation) has carried out optimization study for proposed
Ennore-Trichy-Madurai LPG pipeline for 2016-17 and 2021-22. This study projects
throughput of 617 TMT in 2016-17 and 809 TMT in 2021-22 for the pipeline and
substantial savings in logistics cost for transportation of LPG. The financial analysis of
laying own LPG pipeline vis--vis use of alternate mode i.e. road has been covered in
details in Chapter-VIII.
3.3 At present, CPCL refinery is producing about 33 TMT of LPG per month. CPCLs
LPG is primarily used for bottling plant at Chennai, non-domestic requirement of
bottling plants in Tamil Nadu, Cuddapah in A.P. and partial requirement of
Devanagonthi bottling plants.
3.4 Most of domestic requirement of LPG at IOCs bottling plants in Tamil Nadu,
Cuddapah in A.P. and partial requirement of Devanagonthi is met from LPG import
terminal at Ennore by Road Tankers.
3.5 Throughput Projections
3.5.1 The supply and distribution plans of LPG for various bottling plants linked to the
proposed pipeline, for 2016-17 and 2021-22, have been projected to be as under.

3.5.2 It may be seen from the above table that out of the projected throughput of 617 TMT
for 2016-17, about 134 TMT and 24 TMT of LPG would be transported through road
from Trichy and Madurai respectively. Similarly, out of the projected throughput of
809 TMT for 2021-22, about 235 TMT and 50 TMT of LPG would be transported
through road from Trichy and Madurai respectively.
Schematic presentations of section-wise projected throughput and nodal movements
for 2016-17 and 2021-22 are given at Attachment 3.1 and 3.2.
3.6 The long-term projected throughput for the pipeline would be as under. For working
out projected demand beyond 2021-22, growth rate of 1.76% has been considered, as
assessed by the Planning Cell of Marketing Division. As the pipeline would originate
from Ennore import terminal, the additional demand would be met by increasing the
imports.

3.7 It is pertinent to mention here that while some of the bottling plant capacities are
projected to be saturated during 2016-17, the demand in attached markets would
continue to increase. Therefore, it would be required to either stretch the capacities of
the existing plants or set up new bottling plants in and around the existing markets to
meet the increased LPG demand as required. Therefore, the pipeline facilities have
been designed considering long-term demand projections.
3.8 For facilitating nodal movement to linked bottling plants from Trichy and Madurai, the
existing unloading bays would be converted to loading bays.
3.9 The transportation requirement of LPG volumes indicated in para 3.6 can be met by
the following alternative modes.
a) By Road
b) By Pipeline
Railway has not been considered as a feasible transportation option for LPG as the
existing bottling plants do not have rail linkage.
3.10 It has been established the world over that pipelines are superior means for
transportation of petroleum products compared to other modes viz. rail, road, tankers
etc. due to their inherent advantages like reliability, economy, safety, flexibility, low
energy consumption, low transit losses and negligible impact on environment.
Construction of new pipelines provides relief to other modes of transportation for
movement of essential commodities and passengers.
3.11 In view of the above, it is proposed to lay Ennore-Trichy-Madurai LPG pipeline for
transportation of LPG from Ennore to the LPG bottling plants at Chengalpet,
Pondicherry, Trichy and Madurai. The proposed pipeline would realign movement of
LPG for certain other bottling plants viz. Salem, Coimbatore, Erode, Ilayangudi and
Tirunelveli from Trichy and Madurai in place of Ennore. Thus, the proposed pipeline
would considerably reduce distances involved in road movements and thereby,
logistics cost.

CHAPTER-VII
7.0 OPERATING COST
7.1 Operating cost of the pipeline system includes the cost of power for mainline pumping
units, utilities, consumables, salaries and wages, administrative overheads, repair and
maintenance etc.
The operating cost corresponding to throughput of 0.9 MMTPA is estimated to be about
Rs.30 crore per annum at December 2012 price level.
Details of the operating cost are given in Attachment-7.1.
7.2 Basis of estimation
7.2.1 Fuel/Power (Electricity)
The project envisages motor driven pumping units at Ennore. For the purpose of
operating cost calculations, tariff for electricity has been considered @ Rs.5.00 per unit.
7.2.2 Utilities
7.2.2.1 Power
Power is also required for operation of the auxiliaries & controls etc. and for
illumination at the stations. Requirement of power is planned to be drawn from State
Grid or by increasing contract demand of existing electricity connections at bottling
plants, if required, and extending to pipeline facilities.
7.2.2.2 Water
There is no major requirement of water for operation of the pipeline system. Water for
fire-fighting will be drawn from the Fire water network of existing facilities of
Marketing.
7.2.3 Manpower
7.2.3.1 The cost towards salaries and wages shown against the labour component in the
operating cost is based on the estimated manpower requirement on the existing scales of
pay and allowances. The manpower requirement, which would be around 82 during
construction and around 76 for operation phase, has been worked out on the basis of
DFR Ennore-Trichy-Madurai LPG Pipeline Page 33 of 38
prevailing norms and practices. The requirement of manpower is expected to be met
through internal deployment as well as by induction of competent personnel, who will
be trained to operate the system.
7.2.4 Repair and Maintenance
7.2.4.1 Repair and maintenance of the mainline has been considered to be about 1% of the
investment in the mainline. Similarly, repair and maintenance of the stations has been
considered to be about 2% of the investment on stations, telecommunication &
telesupervisory system.
7.2.5 General Administration Expenses
7.2.5.1 The cost under this head covers management expenses including security services,
insurance of facilities etc. being proposed in the pipeline system.

CHAPTER - VIII
8.0 FINANCIAL ANALYSIS
8.1 Project Financing
8.1.1 Capital cost of the project is considered to be financed through internal
resources/commercial borrowings. For the purpose of financial analysis, Debt:Equity
ratio of 1:1 has been considered, with interest rate of 10.75% per annum and repayment
in 8 equal installments, with one year moratorium from the date of commissioning.
Requirement of working capital will be met through internal resources.
8.2 Financial Analysis
8.2.1 Financial analysis for the proposed pipeline system has been carried out taking into
account the following.
Capital cost of the pipeline and its operation for 15 years / 25 years
Throughput as indicated in the optimization study for 2016-17 and 2021-22
Corporate savings, as assessed in the optimization study, as Revenue
Benefit due to lower transit loss in pipeline transportation compared to losses
permitted for transportation through road tankers
Savings in the loading and decanting charges associated with road tankers on
notional basis
Results of the financial analysis are as under.
15 years operation 25 years operation
ROI (%) 16.2 17.5
ROE (%) 19.8 21.1
8.2.2 Sensitivity analysis has also been carried out, the results of which are as under.

8.2.4 It is seen from the above that the proposed pipeline is viable under most of the
scenarios considering the prevailing hurdle rate of 13%. The pipeline will facilitate
cost-effective transportation of LPG from Ennore to LPG bottling plants at
Chengalpet, Pondicherry, Trichy and Madurai.

CHAPTER IX
9.0 CONCLUSIONS AND RECOMMENDATIONS
9.1 With commissioning of IPPLs LPG import terminal at Ennore, which was set up
primarily to meet the deficit of LPG in Tamil Nadu, requirement of domestic category
of LPG for various bottling plants in Tamil Nadu, Cuddapah in A.P. and part
requirement of Devanagonthi is met from Ennore by road tankers.
9.2 Most of the LPG bottling plants in Tamil Nadu are situated at considerable distance
from Ennore. Optimization study indicates that there would be considerable savings by
laying a LPG pipeline from Ennore to Madurai via Chengalpet, Pondicherry and
Trichy, which would substitute road movement of LPG ex-Ennore to these bottling
plants.
9.3 The proposed pipeline will facilitate cost-effective transportation of LPG from Ennore
to different bottling plants in the state of Tamil Nadu and also at Pondicherry in a safe,
cost-effective, environment-friendly and reliable manner. The pipeline would replace
significant movement of LPG by road tankers and would thus provide relief from
problems associated therewith
9.4 In view of the above, it is proposed to lay Ennore-Trichy-Madurai LPG pipeline which
would originate at Ennore and terminate at existing Madurai bottling plant, providing
pipeline connectivity en route to the existing LPG bottling plants at Chengalpet,
Pondicherry and Trichy.
9.5 Results of the financial analysis indicate that the proposed LPG pipeline is viable
considering the prevailing hurdle rate of 13%.
9.6 Keeping the above in view, it is recommended to consider this pipeline at an estimated
cost of Rs.711 crore including a foreign exchange component of Rs.202 crore, at
December 2012 price level.
9.7 The project is estimated to be completed in a period of about 30 months after receipt of
all statutory clearances.
