Act, 1998 (14 of 1998) on February 28, 2001. The Commission is mandated to

exercise the powers conferred under Section 181 of the Electricity Act, 2003 (36 of

2003) (hereinafter referred to as “the Act” or “the EA, 2003”) and to exercise the

functions conferred on it under Section 86 of the Act from June 10, 2003.

1.2.1. Under Section 61 of the Act in the determination of tariffs, the Commission is to be

guided by the following:

(a) The principles and methodologies specified by the Central Commission for

determination of the tariff applicable to generating companies and transmission

licensees;

(b) The electricity generation, transmission, distribution and supply are conducted

on commercial principles;

(c) The factors, which would encourage competition, efficiency, economical use of

the resources, good performance, Optimum investments, and other matters

which the State Commission considers appropriate for the purpose of this Act;

(d) The interests of the consumers are safeguarded and at the same time, the

consumers pay for the use of electricity in a reasonable manner;

(e) That the tariff progressively reflects the cost of supply of electricity at an

adequate and improving level of efficiency and also gradually reduces cross

subsidies;

(f) The National Electricity Plans formulated by the Central Government including

the National Electricity Policy and Tariff Policy.

1.2 Multi Year Tariff Regulations, 2015

2.3 Capital Investment Plan

2.3.1 AEGCL submitted the Capital Investment Plan under various heads such as

Strengthening & Augmentation of existing network, expansion of transmission

network, plan for evacuation of power, IT application, reduction of Transmission

losses, system reliability and efficiency improvement, metering plan, network

expansion and reactive power management. AEGCL has projected the total

investment of Rs. 2457.69 Crore during the Control Period from FY 2016-17 to FY

2018-19. AEGCL has projected the capacity addition of 5184.50 MVA and network

addition of 3244.50 ckt-km based on this investment.

2.3.2 It may be noted that AEGCL has only submitted the capital expenditure against each

Scheme and has not submitted the scheme-wise capitalisation, except for some On-

going projects.

2.3.3 AEGCL submitted that the total investment proposed is in line with Power for All

roadmap and sufficient for meeting Power for All roadmap objectives. The details of

the projects have been discussed below:

2.3.4 Strengthening & Augmentation of Existing Network

2.3.4.1 AEGCL submitted that the present network has the capacity to handle 1628 MW

peak load, which will increase to 1900 MW after commissioning of all On-going

projects. AEGCL submitted that it has considered the present constraints in

transmission network while planning for the schemes related to Strengthening &

Augmentation of Existing Network. Some of the constraints as highlighted by

AEGCL are:

a) The Lower Assam districts mainly Kamrup (Rural), Nalbari, Baksa, Barpeta, and

Dhubri are facing load shedding to the tune of 50 MW due to constraints in

network.

b) Some of the critical corridors like BTPS – Dhaligaon 132kV D/C line, LTPS-

Mariani 132kV S/C line, and Sonabil –Depota 132kV S/C line are more than 30

years old. These lines require strengthening through replacement with efficient

conductors like High Temperature Low Sag (HTLS).

17

c) Some of the Substations are radially connected with a single circuit only.

d) Power & Auto transformers of some of the critical sub-stations have mostly

completed their insulation life and are also being operated at critical load.

2.3.4.2 AEGCL submitted that the total project cost against the new Strengthening &

Augmentation schemes is Rs. 1815.81 Crore, to be initiated during the Control

Period. These projects include the project under NERPSIP 2nd Tranche and AEGCL

Plan. Some of the projects initiated by Ministry of Power in 2009 like NERPSIP 1st

Tranche have been considered under AEGCL Plan, but till date there is no clarity

regarding the funding pattern.

2.3.4.3 The North Eastern Region Power System Improvement Programme (NERPSIP) 2nd

Tranche projects are extremely essential for system strengthening. The projected

cost for the NERPSIP 2nd Tranche projects is Rs. 886.72 Crore. AEGCL has

proposed that under this scheme, Rs. 45.44 Crore will be invested during FY 2017-

18 & Rs. 446.59 Crore during FY 2018-19 and the remaining investment will be

done beyond the Control Period. AEGCL has considered the funding of capital

investment from the Asian Development Bank (ADB)/Japan International Co-

operation Agency (JICA) and equity.

2.3.4.4 The balance amount of Rs. 929.10 Crore (Rs. 1815.81 crore - Rs. 886.72 crore) is

to be arranged either from ADB or JICA. Out of this Rs. 929.10 Crore, AEGCL has

proposed the capital investment of Rs. 45.78 Crore in FY 2017-18 and Rs. 436.63

Crore in FY 2018-19. It is observed that there is difference in submissions made by

AEGCL regarding capital investment for NERPSIP projects. The list of schemes

showing the investment of Rs. 886.72 Crore has been considered. The remaining

investment is considered beyond the Control Period. AEGCL has already initiated

preliminary discussions with both ADB and JICA and is preparing Detailed Project

Reports (DPRs) for the projects planned.

2.3.4.5 AEGCL in its Business Plan Petition has submitted the list of schemes related to

sub-station, transmission lines and bays for projects under NERPSIP 2nd Tranche

and AEGCL Plan.

2.3.4.6 AEGCL has also considered on-going projects, which have commenced before the

beginning of the Control Period and targeted to be completed in FY 2016-17.

AEGCL has considered the capital investment of Rs. 61.70 Crore in FY 2016-17 for

18

such on-going projects. The summary of Capital Investment proposed by AEGCL

for strengthening and augmentation of existing network is summarised in the

following Table:

2.3.5 Expansion of Transmission Network

2.3.5.1 AEGCL submitted that the Government of India and Government of Assam have

prepared 24x7 Power for All document with a view to provide reliable power to

existing consumers as well as electrification of rural and left out households in the

State. The document mentions that still 46% rural households are yet to be

electrified. The new load centres are already identified in the document and

accordingly, the expansion of transmission network for catering to the demand has

been considered. AEGCL has considered project cost of these new projects to be

initiated during the Control Period as per 24x7 'Power for All' roadmap as Rs.

613.31 Crore. The proposed Capital Investment during the Control Period is Rs.

2.3.6 Plan for Evacuation of Power

2.3.6.1 AEGCL has considered the transmission schemes for evacuating power from State

Generators and from Central Transmission Utility’s interface. AEGCL has proposed

evacuation plan for Lower Kopili HEP (LKHEP), for which APGCL has proposed the

target of completion by FY 2020-21. AEGCL submitted that evacuation plan for

upcoming generators must be completed well ahead, since transmission project

always takes sizable time because of forest clearance and Right of Way (ROW)

issues.

2.3.6.2 Assam will get 500 MW Bhutan power in a phased manner in the Control Period

with quantum of 123 MW from Mangedechhu in FY 2016-17, 173 MW from

Punatchangshhu-II in FY 2017-18 and 204 MW from Punatchangshhu-I in FY 2018-

19. Further, NTPC-Bongaigaon will generate at full capacity by FY 2017-18 and

Assam's share of 381 MW is to be evacuated from CTU’s interface points. The

proposed evacuation plan will be able to evacuate Bhutan, Central Generating

Station power and LKHEP.

2.3.6.3 DPR for this project will be submitted to ADB through the Government of Assam

and Government of India. The sanction of fund is expected by the end of FY 2016-

20

17 and funds will be available by mid of FY 2017-18. The total fund requirement is

Rs. 589.64 Crore and equity portion will be Rs. 165.36 Crore, i.e., 28.04%.

2.3.6.4 The completion of evacuation system for LKHEP will take 36 months from Zero

date, however, 400 kV Rangia may be completed by FY 2019-20 and accordingly

financial phasing plan has been considered.

2.3.6.5 AEGCL has proposed total project costs for new projects for evacuation of power

as Rs. 594.84 Crore. AEGCL has considered the phasing of such investment as

Rs. 13.86 Crore in FY 2017-18 and Rs. 219.81 Crore in FY 2018-19, and the

remaining expenditure will be incurred beyond the Control Period.

2.3.7.3 Some substations, which are mostly radial with trunk line, are not connected by

OPGW. Hence, AEGCL has proposed OPGW communication links for such

substations, which requires replacement of 1531.5 km of transmission line ground

wire by OPGW. AEGCL has envisaged the following benefits of this project:

a) All the EHV substations will come under Fibre Optic network and there will

be good communication backbone.

b) Authentic Real time data will be received.

c) Option for remote operation and control of the EHV substation will be

available in future.

d) 6 pairs out of 24 pairs of Fibre Optic are more than sufficient for

communication and tele protection system.

e) Increase in reliability, efficiency and availability as faster decision can be

made.

f) All townships within the State will be covered.

g) Demand Side Management (DSM) application can be implemented.

h) Option for leasing of fibre will be available.

2.3.7.4 AEGCL has proposed the total project cost of Rs. 39.04 Crore for new projects to

be initiated during the Control Period. AEGCL has considered the phasing of such

investment as Rs. 15.62 Crore in FY 2017-18, Rs. 19.52 Crore in FY 2018-19 and

Rs. 3.90 Crore in FY 2019-20.

2.3.9 System Reliability and Efficiency Improvement

2.3.9.1 AEGCL has considered the up-gradation and renovation of EHV substations older

than 8 years for increasing the reliability and efficient operation. It has submitted a

23

DPR to the Ministry of Power (MoP), Government of India (GoI) in FY 2014-15, for

sanction of Rs. 382.48 Crore against Power System Development Fund (PSDF) for

up-gradation of existing obsolete switchgear equipment and introduction of IEC

61850 based numerical protective relays in 48 numbers of EHV substations, which

include existing three sub-stations at generating stations, viz. Namrup, Lakwa and

KLHEP. AEGCL has submitted the detailed list of EHV substations included in the

said DPR. The GoI has sanctioned the fund in two separate Orders of Rs. 299.37

Crore in May 2015 and Rs. 53.52 Crore in October 2015. The State level taxes and

expenditure towards local automation system of Rs. 42.93 Crore is excluded from

the PSDF fund. The tripartite agreement between nodal agency of PSDF,

Government of Assam and AEGCL was signed in February 29, 2016 and the first

instalment of Rs. 12.97 Crore against Letter of Award (LOA) issued to vendors

regarding procurement of switchgear equipment like Circuit Breakers of various

voltage levels, etc. The time of completion of this project is eighteen (18) months

from the date of signing of aforementioned agreement, i.e., September 2017.

2.3.9.2 AEGCL, as a part of system efficiency improvement, has considered modern

technology as a part of disaster management like Tower collapse, etc., through

Emergency Restoration System (ERS). It consists of set of poles, which can be

installed within a day and transmission line can be restored from next day. AEGCL

has procured two sets of ERS, which have been placed at Kahilipara and Mariani.

AEGCL is planning for four sets of ERS towers at Dhaligaon, Tezpur, Tinsukia and

Silchar in order to reduce transportation time.

2.3.9.3 AEGCL has also considered the capital investment of Rs. 224 Crore in FY 2016-17

and Rs. 156.29 Crore in FY 2017-18 towards On-going projects, which have been

initiated before the Control Period and projected to be completed in FY 2017-18.

2.3.9.4 The summary of Capital Investment proposed by AEGCL for these schemes is

2.3.10 Metering Plan

2.3.10.1 AEGCL has installed ABT compliant meters at Distribution Licensee’s interface, i.e.,

LV side of power transformers and at inter-State transmission line. The meters for

EHV line feeders, ICTs, HV side of power transformers and 33 kV outgoing feeders

are mostly non-ABT compliant and have an accuracy class of 0.5 or more. Since,

Protection and Control System will be upgraded by IEC 61850 compliant numeric

relays and local automation at existing 45 numbers of EHV substations and 3

numbers of generating substations, the energy meters for all type of feeders will

also be replaced by communicable ABT meters. All new EHV substations

commissioned in the 12th Plan already have ABT compliant meters and only

communication links are required to receive data centrally at SLDC.

2.3.10.2 Under PSDF, AEGCL will replace all Control and Relay panel with IEC 61850

compatible numeric relays. The summary of Capital Investment proposed by

AEGCL for Metering Plan is summarised in the following Table:

2.3.11 Network Expansion

2.3.11.1 AEGCL submitted that the transmission network in the State primarily consists of

132 kV network. The planned network growth is dependent on availability of funds.

Whenever funds are available, AEGCL has to create sub-stations compromising the

basic transmission criteria, i.e., N-1. Therefore, any eventuality in the system leads

25

to total black out at the area under that sub-station. AEGCL is planning to fill the

gap in a phased manner and as per guidelines from statutory authority like CEA.

2.3.11.2 AEGCL has proposed the total cost of Rs. 152.24 Crore for various projects under

network expansion to be initiated during the Control Period. AEGCL has considered

the phasing of such investment as Rs. 10.04 Crore in FY 2017-18 and Rs. 79.71

Crore in FY 2018-19, and the remaining expenditure will be incurred beyond the

Control Period.

equipment for the required reactive power, except for 220 kV and 400 kV system.

The shunt reactors are not considered for long 220 kV lines with the increase of the

220 kV system, as earlier line reactors have been installed. However, to get rid of

high voltage in 400 kV sub-station, shunt reactors will be installed at bus.

2.3.13 On-going projects

2.3.13.1 AEGCL has submitted the list of on-going transmission projects being undertaken

by PGCIL along with their physical and financial progress.

2.3.13.2 Further, AEGCL submitted that the 1st Tranche of NERPSIP Central Sector on-

going Projects being implemented by PGCIL, include 11 numbers of new sub-

26

stations of which 2 substations are of 220/132 kV level and rest are at 132/33 kV

level. The projects also include all the associated transmission lines and network

addition by FY 2018-19, as under:

a) Transformer Capacity of 690 MVA at 220/132 kV level and 494 MVA at 132/33

kV level

b) Transmission line of 176 ckt-km at 220 kV level and 200 ckt-km at 132 kV level.

3.2.2 During scrutiny of the Petition, the Commission asked AEGCL to submit the scheme-

wise details in the requisite format for various transmission works proposed during

the Control Period. It is also noted that AEGCL has proposed the Capital Investment

Plan in line with the 'Power for All' roadmap.

3.2.3 As regards the funding of capital structure, Regulation 32 of MYT Regulations, 2015

specifies as under:

“32 Debt-equity ratio

32.1 For a project declared under commercial operation on or after April 1,

2016, a normative debt:equity ratio of 70:30 would be considered as on COD.

If the equity actually deployed is more than 30% of the capital cost, equity in

excess of 30% shall be treated as normative loan for the Generating

Company, Transmission Licensee and Distribution Licensee.

Provided that where equity actually deployed is less than 30% of the capital

cost of the capitalised asset, the actual equity shall be considered for

determination of tariff:

Provided further that the equity invested in foreign currency shall be

designated in Indian rupees on the date of each investment.

Provided that any grant obtained for the execution of the project shall not be

considered as part of capital structure for the purpose of debt: equity ratio.

Explanation.- The premium, if any, raised by the Generating Company or the

Transmission Licensee or the Distribution Licensee, as the case may be,

while issuing share capital and investment of internal resources created out of

its free reserve, for the funding of the project, shall be reckoned as paid up

capital for the purpose of computing return on equity, provided such premium

amount and internal resources are actually utilised for meeting the capital

expenditure of the Generating Station or the transmission system or the

distribution system.

33

32.2 In case of the Generating Company, Transmission Licensee, Distribution

Licensee and SLDC, if any fixed asset is capitalised on account of capital

expenditure prior to April 1, 2016, debt-equity ratio allowed by the

Commission for determination of tariff for the period ending March 31, 2016

shall be considered:

Provided that in case of retirement or replacement of the assets, the equity

capital approved as mentioned above, shall be reduced to the extent of 30%

(or actual equity component based on documentary evidence, if it is lower

than 30%) of the original cost of the retired or replaced asset.

32.3 Any expenditure incurred or projected to be incurred on or after April 1,

2016, as may be admitted by the Commission as additional capital

expenditure for determination of tariff, and renovation and modernisation

expenditure for life extension, shall be serviced in the manner specified in this

Regulation.”

3.2.4 The above said Regulation specifies the normative debt:quity ratio of 70:30 for

determination of tariff. In case actual equity is less than 30% of capital cost of the

capitalised asset, then actual equity shall be considered. Also, the Regulation

specifies that any grant obtained for the project shall not be considered as part of

capital structure for the purpose of debt: equity ratio, i.e., in other words, the

normative debt:equity ratio has to be considered, after reducing the amount of grant

funding.

3.2.5 AEGCL has proposed the funding of capital expenditure. The determination of tariff

including ARR component such as the interest, depreciation, and RoE are dependent

on the capitalisation, rather than the capital expenditure. The capitalisation are

allowed only after the asset is put to use, i.e., capitalised. Hence, the Commission

while provisionally approving the Capital Investment Plan, has also considered the

normative funding of estimated capitalised works, along with Capital expenditure.

3.2.6 Though AEGCL has not submitted the scheme-wise capitalisation in some cases, the

Commission has considered the scheme-wise capitalisation by considering the

amount in the year in which the all capital expenditure is incurred and scheme is

projected to be completed, i.e., put to use.

34

3.2.7 The Commission has computed normative funding of estimated capitalised works as

per the provisions of MYT Regulations, 2015, which can be considered as input for

the determination of Tariff. The Commission has provisionally approved the Grant for

each project as proposed by AEGCL The grant considered against each project has

been excluded for the purpose of debt:equity ratio. The Commission has considered

the actual equity proposed by AEGCL subject to maximum of 30% of estimated

capital cost of the project, after reducing the amount funded by grants. Further, in

many cases, the equity considered by AEGCL is much higher than the normative

30% of capitalisation, after reducing the grant component. However, the Commission

has restricted the equity component to maximum of 30% of amount of capitalised

works, after reducing the grant component. The balance amount has been

provisionally approved as funded by loans.

3.2.8 The Commission's analysis and ruling on the scheme-wise Capital Investment Plan

proposed by AEGCL in its Business Plan Petition are discussed in subsequent

sections as under:

3.2.9 Strengthening and Augmentation of Existing Network

3.2.9.1 The Commission notes that AEGCL has considered network strengthening projects

planned by Ministry of Power, GOI in 2009 under AEGCL Plan. However, AEGCL

does not have any clarity regarding the funding for these projects. AEGCL has

considered the projects under NERPSIP and projects planned by AEGCL.

3.2.9.2 The Commission scrutinised the details of transmission schemes submitted by

AEGCL. The Commission notes that AEGCL has considered four (4) On-going

schemes of total cost of Rs. 205.69 Crore to get completed during the Control

Period. Such schemes include 220/132 KV Sonapur Sub-station (Rs. 16.95 Crore),

LILO of 220 kV Samaguri – Sarusajai at Sonapur (Rs. 4.12 Crore), LILO of

Chandrapur – Narengi-Kahilipara at Sonapur (Rs. 3.56 Crore), and Rangia –

Salakathi 220 kV D/C line (Rs. 37.07 Crore). AEGCL has proposed to incur

expenditure of Rs 61.70 Crore for these schemes during FY 2016-17. Accordingly,

the Commission has provisionally considered the Capital Investment for these on-

going schemes for FY 2016-17.

3.2.9.3 As regards the new System Strengthening and Augmentation projects, during the

technical discussions, AEGCL submitted that the work related to Makum

35

220/132/33 kV Sub-station (2 x 100 MVA and 2 x 40 MVA) along with associated

transmission lines will be executed in the 13th Plan period and will be up-graded to

400 kV level if Margherita Generation (1 x 660 MW) is connected to the network.

The Commission notes that APGCL in its Business Plan Petition has considered

the commissioning of Margherita Generating Station beyond the Control Period. In

view of this, the Commission has not considered the capital investment related to

schemes of Makum Sub-station and associated transmission lines for the present

Control Period.

3.2.9.4 Further, AEGCL intimated that Central Transmission Utility is planning to

commission a 400 kV Sub-station at Lakhimpur District. Hence, the commissioning

of 220/132 kV Silapathar Sub-station along with associated transmission lines

would have to be deferred for implementation. In view of this, the Commission has

not considered the Capital Investment for such schemes for the present Control

Period.

3.2.9.5 As regards transformer capacity augmentation, the Commission notes that AEGCL

has proposed the requirement of new transformers of capacity 25 MVA. However,

during the technical discussions, AEGCL submitted that AEGCL will utilise the

existing transformers of 25 MVA, which would be available after the augmentation

of such existing 25 MVA transformers to 40 MVA/50 MVA transformers. Hence,

there will be requirement of transformers of higher capacity only and no

requirement for new transformers of capacity 25 MVA is to be considered. The

Commission has found this approach of AEGCL to be cost effective and

accordingly considered the revised cost of schemes where 25 MVA transformers

were proposed.

3.2.9.6 AEGCL submitted the target year of completion against each scheme. The

Commission notes that for some schemes, AEGCL has proposed the capital

investment even during the year immediately after the proposed completion year.

Therefore, for all the schemes, the Commission has considered the year when all

investment is completed as the completion year for the project.

3.2.9.7 AEGCL submitted during the various technical discussions after submission of

Business Plan, that considering the priority of the works, some schemes may be

required to be advanced or postponed. For example, Srikona (2X25 MVA to 2X40

MVA) and Sarusajai (3X100 MVA to 2X160 MVA) are advanced to FY 2016-17.

36

The same is provisionally approved accordingly.

3.2.9.8 As regards the funding of this capital expenditure, the Commission notes that for

new projects, AEGCL has considered the funding from ADB/JICA & Equity. The

Commission has provisionally approved the funding of capital expenditure as

proposed by AEGCL.

3.2.9.9 Accordingly, the Commission has provisionally approved the capital investment and

its funding for Strengthening and Augmentation of Existing projects for the Control

Period as shown in the following Table:

Further, the Commission has considered normative funding of capitalised works as

discussed in para 3.2.7 of this Order. Considering the fact that this Business Plan

will act as basis for MYT, the Commission has provisionally approved the

capitalisation and funding of the capitalised works as shown in the following Table:

3.2.10 Expansion of Transmission Network (Existing)

3.2.10.1 During the scrutiny of the Petition, the Commission observed that AEGCL has

proposed schemes under two heads, viz., Expansion of transmission network and

Network expansion. In reply to the query regarding any duplication of transmission

schemes under these two heads, AEGCL submitted that in Expansion of

Transmission network, it has considered the schemes towards the expansion of

existing network, however, new network expansion has been proposed under the

other head.

3.2.10.2 The Commission scrutinised the details of transmission schemes submitted by

AEGCL under expansion of transmission network. The Commission observes that

AEGCL has considered 17 Nos. of On-going schemes with total capital investment

of Rs. 96.65 Crore in the Control Period. Out of total 17 Nos. of schemes, 6

schemes are related to Sub-station amounting to Rs. 29.47 Crore and 11 schemes

are associated with Transmission lines amounting to Rs. 67.18 Crore. AEGCL has

proposed to complete these schemes during the Control Period. The Commission

has provisionally approved the Capital Investment proposed against such On-going

schemes as submitted by AEGCL.

38

3.2.10.3 As regards new schemes proposed during the Control Period, the Commission

notes that AEGCL has proposed schemes under the 2nd Tranche of NERPSIP and

proposed schemes for new load centres as per 'Power for All' roadmap. For sub-

station related schemes where the transformer of 25 MVA has been proposed, the

Commission has provisionally considered the revised cost of schemes as discussed

in earlier section. During the various technical discussions with AEGCL, it was

observed that the proposed transmission schemes will be delayed considering the

execution of On-going schemes and actual capital expenditure for FY 2015-16. The

Commission has provisionally approved the revised phasing of capital expenditure

based on the technical discussions with AEGCL.


new projects, AEGCL has considered a part of funding from ADB/JICA. The

Commission has provisionally approved the funding of Capital Expenditure as

proposed by AEGCL.

3.2.10.5 In view of the above, the Commission has provisionally approved the Capital

investment and its funding for expansion of transmission network for the Control

Period as shown in the following Table:

3.2.10.6 As regards the target year of completion, the Commission notes that for some

schemes, AEGCL has proposed the investment in FY 2019-20, which is after the

proposed projected completion year of FY 2018-19. For such schemes, the

Commission has considered the target year of completion as FY 2019-20.

3.2.10.7 Since, all new projects will be completed in FY 2019-20, which is beyond the

Control Period, the Commission has not considered any capitalisation for such new

projects during the Control Period. Accordingly, the funding of capitalised works has

not been considered.

3.2.10.8 For on-going projects, the Commission has considered normative funding of

capitalised works as discussed in para 3.2.7 of this Order. The capitalisation and

funding of capitalised works is as shown in the following Table:

3.2.11 Plan for Evacuation of Power

3.2.11.1 AEGCL has proposed transmission schemes with total investment of Rs. 594.84

Crore, out of which Rs. 233.67 Crore has been proposed during the Control Period.

The schemes are proposed for evacuation of power from LKHEP of APGCL and

40

CTU Rangia Sub-station. The Commission notes that no On-going schemes have

been considered under this Plan for evacuation of Power.

3.2.11.2 During the technical discussions, AEGCL intimated that the 400/220 kV Rangia

sub-station (2 x 500 MVA) will be executed by Central Transmission Utility (CTU)

now, under Tariff Based Competitive Bidding (TBCB) process and the process is

going on. In that sub-station, CTU will provide four (4) bays of 220 kV to AEGCL for

evacuation of power. In view of this, AEGCL has dropped the commissioning of

400/200 kV, 2 x 500 MVA transformers. Accordingly, the Commission has not

considered the scheme of 2x500 MVA, 400/220kV Transformers at CTU’s proposed

Rangia (PGCIL) Substation.

3.2.11.3 As regards the evacuation of power from LKHEP, AEGCL has considered the

completion of evacuation system of LKHEP in 36 months from Zero date. The

Commission notes that APGCL in its Business Plan has revised the Zero date for

LKHEP as September, 2016. The phasing of capital expenditure of such schemes

would be revised considering the revised timelines proposed by APGCL for

commissioning of LKHEP. Accordingly, the Commission has provisionally approved

the phasing of capital expenditure of such schemes as per revised timelines based

on technical discussions with AEGCL.

3.2.11.4 As regards the funding of this capital expenditure, AEGCL submitted that ADB

funds will be available by mid of FY 2017-18. The Commission has provisionally

approved the funding of works as proposed by AEGCL for the Control Period.

3.2.11.5 In view of the above, the Capital Investment and its funding provisionally approved

by the Commission for evacuation of power for the Control Period is shown in the

following Table:

3.2.11.6 As regards the capitalisation, the Commission notes that all projects proposed for

evacuation of power will be completed beyond the Control Period. Accordingly, the

Commission has not considered any capitalisation for new projects.

3.2.12 IT Application

3.2.12.1 As regards the IT Application schemes, AEGCL has proposed total capital

investment of Rs. 39.04 Crore for new projects, out of which Rs. 35.13 Crore has

been proposed during the Control Period. The new project includes the

replacement of ground wire by OPGW for total length of 1531.5 km.

3.2.12.2 The Commission notes that AEGCL has also considered On-going capital

investment schemes of Rs. 14.05 Crore during the Control Period, for renovation of

Power Line Carrier Communication system and protection software for Relay

database management. AEGCL has proposed the completion of these schemes by

FY 2017-18. The Commission has provisionally approved the capital expenditure

and the funding of such On-going schemes as submitted by AEGCL during the

Control Period.

3.2.12.3 As regards the new schemes for replacement of ground wire by OPGW for total

length of 1531.5 km, the Commission notes that AEGCL has proposed 13 links for

OPGW connecting radial and trunk line. The Commission has perused the benefits

of schemes submitted by AEGCL.


new projects, AEGCL has considered funding from ADB/JICA. The Commission

has provisionally approved the funding of capital expenditure as proposed by

AEGCL.

3.2.12.5 In view of the above, the Commission has provisionally considered the capital

investment and its funding for IT Application for the Control Period as shown in the

following Table:

3.2.12.6 As regards the target year of completion, the Commission notes that for new

projects, AEGCL has proposed the investment in FY 2019-20, which is after the

projected completion year of FY 2018-19. For such schemes, the Commission has

considered the target year of completion as FY 2019-20. Since, new project will be

completed in FY 2019-20, which is beyond the Control Period, the Commission has

not considered any capitalisation for such new projects during the Control Period.

3.2.12.7 As regards the funding of capitalised works, the funding has not been considered

for new projects. For On-going projects, the Commission has considered normative

funding of capitalised works as discussed in para 3.2.7 of this Order. The

capitalisation and funding of capitalised works for IT Application is as shown in the

3.2.13 Reduction of Transmission Losses

3.2.13.1 As regards the reduction of transmission losses, AEGCL has projected new capital

investment of Rs. 83.71 Crore, out of which investment amounting to Rs. 76.56

Crore is proposed in the Control Period, entirely in FY 2018-19.

3.2.13.2 The Commission notes that no on-going schemes have been considered for

reduction of transmission losses. In the proposed new schemes, AEGCL has

considered the replacement of existing lines with low loss HTLS conductors. The

proposed replacement has been considered for the following transmission lines:

a) Sonabil – Depota 132kV S/C line

b) LTPS – Mariani 132 kV S/C line

c) BTPS - Dhaligaon 132kV D/C line

d) Kukurmara – Sarusajai 220kV D/C line

3.2.13.3 As regards Sonabil – Depota 132kV S/C line, the Commission notes that AEGCL

has proposed to replace the existing ACSR conductor by new generation ACCC

HTLS conductors, which can reduce the loss by around 40% as compared to the

existing conductor and increase the power carrying capacity. It is noted that the

demand of associated substations is nearly 109 MW as against the existing

capacity of 60 MW. AEGCL has proposed this option instead of proposing

additional 132 kV line because of non-availability of corridor. The Commission finds

the approach adopted by AEGCL justified and has provisionally considered the

capital investment against this scheme.

44

3.2.13.4 The Commission notes that BTPS - Dhaligaon 132kV D/C line can carry maximum

power of 65 MW per circuit, which leads to 40 MW to 50 MW load shedding in

Lower Assam. Hence, AEGCL has proposed the scheme to increase the power

carrying capacity of the line. Further, AEGCL also submitted that the Kukurmara –

Sarusajai 220 kV D/C line is treated as the main artery to Guwahati City. Presently,

average loading of both the circuits is about 70%. AEGCL has proposed the

scheme to eliminate the issue of system security and to reduce line loss.

3.2.13.5 The Commission finds the schemes proposed by AEGCL for reduction of

transmission losses justified. In view of this, the Commission has provisionally

approved the capital investment and its funding for reduction of transmission losses

for the Control Period as shown in the following Table:

Table 3-8: Capital Investment and its funding for Reduction of transmission losses as provisionally approved by the Commission (Rs. Crore)

3.2.13.6 As regards the target year of completion, the Commission notes that AEGCL has

proposed the investment of Rs. 7.14 Crore in FY 2019-20, which is after the

projected completion year of FY 2018-19. For such schemes, the Commission has

provisionally approved the target year of completion as FY 2019-20.

3.2.13.7 Since, projects for reduction in transmission losses will be completed in FY 2019-

20, which is beyond the Control Period, the Commission has not considered any

capitalisation and funding of capitalised works for such projects during the Control

Period.

3.2.14 System Reliability and Efficiency Improvement

3.2.14.1 As regards System Reliability and Efficiency Improvement, AEGCL has proposed

capital investment towards up-gradation and renovation works of existing

equipments to improve the reliability and ensure efficient operations.

45

3.2.14.2 The Commission notes that AEGCL has considered capital investment of Rs.

380.29 Crore for five (5) on-going schemes in FY 2016-17 and FY 2017-18. These

schemes are proposed for replacement of old and obsolete switchgear equipment

of existing 45 numbers EHV Substations (Rs. 80.13 Crore), Up-gradation of existing

Control and Protection system to IEC 61850 based system (Rs. 193.67 Crore),

Procurement of Diagnostic Tools (Rs. 29.68 Crore), Strengthening of existing

switching scheme and earthing system (Rs. 16.30 Crore), Redundancy in station

auxiliary systems, and Retrofitting of Nitrogen Fire Fighting System for existing

transformers (Rs. 60.51 Crore). AEGCL has proposed the completion of these

schemes in FY 2017-18. The Commission has provisionally approved the capital

investment and its funding for such On-going schemes as proposed by AEGCL in

FY 2016-17 and FY 2017-18.

3.2.14.3 The Commission notes that AEGCL has proposed a new scheme of Rs. 26.49

Crore for procurement of Emergency Restoration System tower at four locations,

viz., Bongaigaon, Tezpur, Tinsukia and Silchar. AEGCL submitted that it has found

some sabotage of transmission towers like theft of tower members, digging near

tower base, etc., which cause the towers to collapse. Normal restoration of

collapsed tower takes more than a week. If the line is critical in nature, then the

area fed by the line is plunged in complete darkness. AEGCL has proposed

Emergency Restoration System to restore collapsed tower within 48 hours. Further,

the Commission directs AEGCL to take efforts to prevent sabotage of transmission

towers. The Commission directs AEGCL to submit actions taken and future plan to

prevent such sabotage of transmission towers, in its MYT Petition.

3.2.14.4 The Commission finds the scheme proposed by AEGCL justified. In view of above,

the Commission has provisionally approved the capital investment and its funding

for System Reliability and Efficiency Improvement for the Control Period as shown

in the following Table:

3.2.14.5 As regards the target year of completion, the Commission notes that for new

projects, AEGCL has proposed the investment of Rs. 2.65 Crore in FY 2019-20

after the projected completion year of FY 2018-19. For such projects, the

Commission has provisionally considered the target year of completion as FY 2019-

20. Since, projects will be completed in FY 2019-20, which is beyond the Control

Period, the Commission has not considered any capitalisation and funding of any

capitalised works during the Control Period.

3.2.14.6 As regards the funding of capitalised works for on-going projects, the Commission

has considered normative funding of capitalised works as discussed in para 3.2.7 of

this Order. The capitalisation and funding of capitalised works for System reliability

and efficiency improvement projects as provisionally approved by the Commission

is shown in the following Table:

3.2.15 Metering Plan

3.2.15.1 As regards Metering Plan, AEGCL has proposed total capital investment of Rs 4.69

Crore for procurement of ABT compliant meters at 45 locations. The whole project

is estimated to be completed by FY 2017-18.

3.2.15.2 The Commission notes that AEGCL has proposed to replace the existing meters by

ABT compliant meters at 45 locations in view of up gradation of Control and

Protection System to IEC 61850 compliant numerical relays and local automation.

AEGCL submitted that it has proposed online data transfer system, to bring the

meters readings in a simplified manner from the client server to main server to be

installed at SLDC, Kahilipara, mostly using optical fibre network and GPS modem

wherever optic fibre communications are not available.

3.2.15.3 The Commission finds the scheme proposed by AEGCL justified and accordingly,

the Commission has provisionally approved the capital expenditure and its funding

as submitted by AEGCL as shown in the following Table:

3.2.16 Network Expansion

3.2.16.1 As regards Network Expansion, AEGCL has proposed total capital investment of

Rs. 152.24 Crore, out of which capital investment of Rs. 89.75 Crore has been

proposed during the Control Period. AEGCL has not considered any On-going

scheme under Network Expansion.

3.2.16.2 The Commission notes that AEGCL has proposed 10 schemes for requirement of

132 kV bay amounting to Rs. 18.98 Crore in FY 2018-19 and Rs. 4.75 Crore in FY

2019-20, which is beyond the Control Period. However, AEGCL has proposed the

completion in FY 2018-19 for such schemes. The Commission has considered the

completion of such schemes by FY 2019-20, which is beyond the Control Period.

Hence, no capitalisation against such scheme is considered by the Commission.

3.2.16.3 The Commission notes that AEGCL has proposed four (4) schemes for

commissioning of new transmission lines, viz., Nagaon – Baghjap 132kV D/C line,

Moran-Sibsagar 132kV D/C line, 2nd Circuit stringing of Samaguri – Nagaon 132 kV

S/C line on D/C Tower and 2nd Circuit stringing of BTPS -Kokrajhar – Bilasipara –

Gauripur 132kV S/C line on D/C Tower. During the technical discussions, AEGCL

submitted the revised priority of these lines wherein it has revised the phasing of

capital expenditure of Nagaon – Baghjap 132kV D/C line and Moran-Sibsagar

132kV D/C line. These two lines are proposed to be completed by FY 2019-20.

Accordingly, the Commission has provisionally approved the revised capital

expenditure for these two lines. AEGCL has proposed the completion of other two

lines by FY 2018-19. However, it has also proposed capital expenditure of Rs. 5.07

Crore for such two lines in FY 2019-20. Hence, the Commission has provisionally

49

approved the completion of these two lines by FY 2019-20.

3.2.16.4 In view of the above, the capital investment and its funding for Network Expansion

for the Control Period is as shown in the following Table:

3.2.16.5 The Commission notes that projects proposed by AEGCL for network expansion

will be completed in FY 2019-20 (12 projects) and FY 2020-21 (2 Projects) beyond

the Control Period. Hence, the Commission has not considered any capitalisation

for such projects during the Control Period.

3.2.17 Reactive Power Management

3.2.17.1 As regards reactive power management, the Commission notes that AEGCL has

proposed shunt reactors for bus in order to reduce high voltages at 400 kV level.

AEGCL submitted that it has no such plan for reactive power management except

at 220 kV and 400 kV system. In view of this, the Commission opines that AEGCL

may submit its requirement for capital investment, if any, for reactive power

management as part of its MYT Petition.

3.2.18.4 The list of schemes along with details of capital expenditure and funding pattern

provisionally approved by the Commission is appended as Annexure 2 to this

Order.

3.2.18.5 AEGCL has not proposed any investment during the Control Period specific for

SLDC. Hence, the Commission has not considered the same in its approval.

3.2.18.6 The Commission in-principle approves the provisional Capital Investment against

new schemes for the Control Period, as detailed above. AEGCL may re-asses the

timelines and priorities of various schemes. The Commission directs AEGCL to

submit the revised Capital Expenditure and Capitalisation in its MYT Petition, if

considered necessary, based on updated status and the tie-up of funds for

undertaking the capital expenditure. The Commission will approve the revised

Capital Expenditure for such schemes in the MYT Order for the Control Period

based on submissions made by AEGCL and justification made therein. Further, the

Commission directs AEGCL to separately project the capitalisation for each year of

the Control Period based on the Capital Works in Progress, capital expenditure

proposed to be undertaken during the year, and the schemes proposed to achieve

completion during each year, along with its MYT Petition.

3.2.18.7 The Commission further directs AEGCL to take prior approval of the Commission in

case of any addition and/or deletion of schemes or any change in funding pattern of

schemes approved in this Order. AEGCL shall also take prior approval of the

Commission in case of any emergency works, apart from the works approved in this

Order, to be carried out during the Control Period.

3.2.18.8 The Commission notes that AEGCL has proposed the Capital Investment in line

with the 'Power for All' Roadmap. In the 'Power for All' document, capital investment

proposed is Rs. 416 Crore in FY 2015-16, Rs. 1119 Crore in FY 2016-17, Rs. 2409

Crore in FY 2017-18, and Rs. 1453 Crore in FY 2018-19 for various projects like

TDF, NLCPR, NERPSIP Tranche 1 & 2, State Plan, etc. These investments were

planned based on actual data and realistic position as available till FY 2014-15. In

the Business Plan Petition, AEGCL has submitted the Capital Investment after

assessing the realistic position till FY 2015-16 and taking into account changes

subsequent to the 'Power for All' roadmap. However, AEGCL stated that the

objective of “Power for All” will be achieved by the proposed CAPEX.

54

3.3 Transmission Loss

3.3.1 Regulation 9 of the MYT Regulations, 2015 requires the Commission to stipulate the

trajectory of Transmission Loss for the Control Period while approving the Business

Plan.

3.3.2 The Commission notes that AEGCL in its Business Plan Petition has projected the

Transmission Loss of 3.64% for FY 2016-17, 3.50% for FY 2017-18 and 3.40% for

FY 2018-19. AEGCL has achieved the actual Transmission loss of 3.84% in FY

2014-15, and has estimated the Transmission loss in FY 2015-16 as 3.64%.

3.3.3 The Commission notes that the 'Power for All' roadmap has considered the

Transmission loss of 4% during the Control Period, which is higher than

Transmission loss projected by AEGCL in its Business Plan Petition as well as the

Transmission loss approved by the Commission for the previous Control Period. The

Commission in Tariff Order for FY 2015-16 had approved Transmission loss of

3.64% for FY 2015-16. It is noted that AEGCL has been investing considerable

amounts on new transmission lines, substations, network augmentation, reduction of

transmission losses, etc. Given the amount of Capital Expenditure approved by the

Commission for the Control Period, the Commission approves the loss reduction of

0.10% for first year of the Control Period, i.e.,, FY 2016-17 and 0.05% for the

remaining years of the Control Period.

3.3.4 The Commission, therefore, approves the Transmission loss level at 3.54%, 3.49%

and 3.44% for FY 2016-17, FY 2017-18 and FY 2018-19, respectively, as shown in

the following Table:

Table 3-17: Transmission Loss approved by the Commission

Particulars FY 2016-17 FY 2017-18 FY 2018-19 Transmission Loss 3.54% 3.49% 3.44%

3.4 Transmission Availability

3.4.1 Regulation 9 of MYT Regulations, 2015 requires the Commission to stipulate the

trajectory of the Transmission Availability for the Control Period while approving the

Business Plan.

55

3.4.2 The Commission notes that AEGCL in its Business Plan Petition has projected the

Transmission Availability of 99.45% for FY 2016-17, 99.50% for FY 2017-18 and

99.50% for FY 2018-19. AEGCL has achieved the actual Transmission Availability of

99.04% in FY 2014-15 and estimated availability of 99.14% for FY 2015-16.

3.4.3 Regulation 67 of the MYT Regulations, 2015 specifies Normative Transmission

Availability of 98% for full recovery of transmission charges and 98.5% for incentive

consideration. Also, the computation and payment of Transmission Charges has

been linked to monthly Transmission Availability computed as per Regulation 71 of

the MYT Regulations, 2015.

3.4.4 The Commission notes that AEGCL has projected the trajectory of Transmission

Availability higher than Normative Transmission Availability as specified in MYT

Regulations, 2015. It is also noted that AEGCL has been investing considerable

amounts on new transmission network, strengthening and augmentation existing

transmission network, system reliability and efficiency improvement, etc., which has

also been considered by the Commission while provisionally approving the Capital

Investment Plan for the Control Period. Hence, the Commission is of view that

AEGCL shall achieve the projected trajectory of Transmission Availability during the

Control Period. The computation of incentive/disincentive on account of Transmission

Availability shall be undertaken during annual performance review and at the end of

Control Period in line with the MYT Regulations, 2015.

3.5 Aggregate Revenue Requirement

3.5.1 The Commission notes that AEGCL has submitted the projected Aggregate Revenue

Requirement for the Control Period for FY 2016-17 to FY 2018-19 as part of

Business Plan Petition. At this stage, the Commission has not considered Aggregate

Revenue Requirement for AEGCL for the Control Period. The Commission shall

consider the same after the submission of revised forecast of Aggregate Revenue

Requirement and true-up Petitions in the MYT Petition.

made by the representatives of the power utilities on the overall power scenario of the State

and also on the Business Plan submitted by each of the three utilities for the MYT Period

2016-17 to 2018-19. He requested the members to take this opportunity to raise various

issues and problems being faced by the consumers and offer suggestions so that effective

strategies and investment could be worked out to improve the overall power sector in the

State. The agenda items were taken up for discussions in seriatim which are briefly recorded

below.

1. Agenda No. 1: Confirmation of the Minutes of the 19th meeting of the State

Advisory Committee (SAC) held on 08-05-2015

The Minutes of the 19th Meeting of the Committee was already circulated among the

Members and Special Invitees. No comment was received on the Minutes. With the

approval of the members, the Minutes of the 19th meeting of the SAC were confirmed.

2. Agenda No. 2: Action taken on the Minutes of the 19th Meeting of SAC.

The action taken report was submitted to the members, which are summarized as

below.

Mr. J.K Sarma MD APGCL gave a brief on the action taken report as per the clause

no 11.2 of the 19th SAC meeting.

Efforts should be made to Minimize operating cost.

Mr. Sarma mentioned that efforts are already taken up to minimize the operating

costs which are elaborated in the section 8.4 of the Business Plan.

59

Under utilisation of capacity should be avoided as far as possible by taking

preventive measures.

The reason for under utilisation of capacity is due to mainly lack of sufficient gas

supply.MD APGCL mentioned that continuous efforts are being made to strengthen

the supply of gas by regular correspondence with OIL, ONGC and MOPNG also.

Execution of work should be expedited.

He mentioned that various geographical terrains, absence of skilled manpower are

the major constraints for the project execution work. Even after so many constraints

he mentioned that APGCL is putting lot of thrust to complete the projects within a

specified time.

There should be policies on procurement and inventory control of Stocks. Physical

verification should be carried out at times.

Mr. Sharma stated that the procurement process of APGCL is as per their rules

only. He stated that APGCL is at present maintaining an online inventory record in

addition with the regular inventory control. Further a physical inventory inspection

had been carried out in the year 2013.Now APGCL is planning to implement ERP

which will help in improving the inventory control.

A proper investment policy should be made by the Companies.

APGCL investment plan is as per the projects as it has identified feasible with

available fuel linkage and possible of future fuel links and other statutory clearances.

Considering this APGCL has already formed an investment plan in the Business Plan

which has been submitted to the Commission.

A disaster management cell should be set up by all the Companies.

MD, APGCL mentioned that disaster management cells are already in placed in all

the power stations.

Audit report should be made available in the Website.

Annual reports of APGCL with audited account of FY 2010-11, FY 2011-12 and

provisional account of FY 2012-13 are already available in the website. Annual

reports with final audited accounts for the FY 2012-13, FY 2013-14 and FY 2014-15

will be uploaded in the website.

Mr. G.K Das MD AEGCL gave a brief on the action taken report as per the clause

no. 6 of the 19th SAC meeting.

Mr. Bimal phukan enquired about the capacity that can be handled by AEGCL.

Mr. Das stated that 1180 MW and 1290 MW were handled during 2013-14 and

2014-15 respectively. Now AEGCL can handle about 1628 MW in Peak Hours but

still there is a constraint in the lower Assam about 40 MW-50 MW. He stated that,

AEGCL recently restored the situation by commissioning a 132 KV line from BTPS to

Kokrajhar ,Kokrajhar to Billasipara and Billasipara to Gauripur. These lines and

substations are already completed and can minimize the constraint of 40MW to 50

MW in the North Bank.

Mr. Nitin Sabikhi Manager IEX desired to know about the Import capacity of AEGCL.

60

Mr. Das mentioned that import capacity mainly dependant on CTU’s interface

points to State. As all of us aware that due to constraint in the Chicken Neck which

connect north East States to the rest of the India. Power import from other regions is

restricted and presently is limited to 1160 MW (TTC) and 1115 MW (ATC). Though

the 800 KV HVDC line was already charged, the ATC is not yet cleared, however the

total import capacity is 3000 MW.

A representative from APDCL gave a brief on the action taken report of the 19th SAC

meeting.

Peak power Tariff in consumer categories is not presently covered under the TOD

Tariff. The Commission had advised APDCL to submit the required information. On

receipt of the same the Commission would be in a position to take a decision.

TOD consumption data of consumers under different categories for FY 2014-15

has been submitted. Data for FY 2015-16 will be submitted along with the Tariff

Petition.

Present power scenario of the State.

In the 19th SAC meeting clause 4.1 of Agenda item No2 Mr. Bimal Phukan desired to

know about the methodology of calculation of demand by APDCL .APDCL apprised

that physical demand recorded in the system is considered to calculate demand. Mr.

Bimal Phukan objected to the same stating that during summer months (4-5months)

load shedding occurs across the state therefore the system will not record the actual

demand. APDCL confirmed that they consider substation wise recorded data for

those days of the month when no load shedding was carried out. However, Mr.

Phukan however opined that the demand data is a suppressed demand data and he

apprehended that if this demand is considered by Central Government for allocation

of power then Assam will get lower allocation of power than actual requirement.

A representative from APDCL mentioned that the demand data is restricted because

of constraints in the Transmission Grid Corridor (132 KV BTPS-Dhaligaon Double

Circuit Line), 132KV Samuguri GSS and the distribution network system. APDCL is

taking steps to eliminate these network constraints under 24X7 Power for all scheme

and in coming years by 2022, the estimated demand forecast of unrestricted power

demand is as follows:

61

Mr. Anup Gogoi, Prof Deptt. EEE IITG mentioned that the growth of the demand gap (MU) is

becoming less as the year progresses. He suggested that the growth should always keep on

increasing and mentioned that APDCL should start pushing for more power.

3. Presentation on the Business Plan and capital investment plan petitions for MYT

period 2016-19 submitted by the respective utilities.

APGCL:

i) Mr. Satyen Kalita APGCL CGM (F&A) made a brief presentation on APGCL’s

Business Plan. The hard copy of the presentation was circulated among the

members. He mentioned that in the FY 2015-16 APGCL has turned around and

made an after tax profit of Rs.92.80 Lakhs.

During the course of the presentation the Commission enquired whether complete

investment of the Silchar Thermal Power Project can be included within the MYT

Period 2016-2019. Mr. Eapen Chairman APGCL informed that ONGC has not

agreed to supply gas to the Silchar project on firm basis. Infact APGCL is required

to arrange the pipelines for transporting the gas to Silchar project from its own

investment. He further informed that for construction of gas pipelines huge

investment is required and APGCL is in correspondence with ONGCL on the issue.

Due to this uncertainty the Silchar project has not been included in the MYT period.

Regarding investment proposed for the existing projects it was informed that the

Company estimated more investment in LTPS in the FY 2016-17 as the LRPP

project is likely to come into operation only after two years. Therefore, investments

are required in Unit5, 6 and 7 of the LTPS plant for better generation during the

year. Mr. Kalita also informed that 30.7 Crores is proposed to be invested against

special R & M of the existing projects.

Mr. Anup Gogoi, Prof Deptt. EEE IITG enquired whether any steps have been taken to

maintain the PH level of the water of the lower Kopili Project. He stated that due to

extensive mining in those areas the PH imbalance is recorded in the water bodies which

adversely affect the equipments of the units. Mr. Kalita explained that this has been a

problem in many projects of the North-East particularly Khangdong where 90% of the

generating equipments had to be replaced.He informed that these aspects has been taken

into consideration while designing the Lower Kopili project for which the project cost have

risen.

Mr. Arup Kumar Dutta, President, AASIA stated that from the presentation, it has become

obvious that APGCL proposed to come up with only 4 MW Solar project. Mr. Dutta wanted

to know as to whether APGCL was planning to set up any project in the future in

collaboration with central Government.

62

Mr J.K. Sarma, MD APGCL mentioned that APGCL took initiative to set up a 60 MW

photovoltaic Solar power project through Joint venture with NEEPCO at Amguri, Sibsagar

District and a MOU was signed on 14th July 2014 subject to approval of Board of Directors

of respective companies for forming a joint venture company. However, at a later stage,

MNRE sanctioned a Solar Park of 69 MW at Amguri for development through JV between

APDCL, Solar Energy Corporation of India & APGCL.He also informed that 100 Bighas of

land has been allotted to MNRE to develop a pilot Solar plant of 6 MW at the Chandrapur

Thermal Power Station (CTPS).Mr. Sarma also informed that APGCL is also planning to set

up two solar projects of 2 MW each in the vacant land at Namrup and Lakua Thermal Project

stations.

The Commission observed that APGCL should come up with a comprehensive plan for Solar

Projects in the State over the next couple of years. The Commission stated that Solar Policy

needs to be drafted for the State by the power department so that technology support can be

provided to attract investments. Mr. Rajiv Bora, Additional CS, Power, GOA informed that

the Department is in the process of drafting a Solar policy and inputs from the Members of

this Committee are most welcome.

ii) Mr. Karuna Sarma AEGCL AGM made a brief presentation on AEGCL’s

Business Plan. The hard copy of the presentation was circulated among the

members.

The following issues were raised during the course of the presentation:

a) Mrs. Susmita Priyadarshini, Member of the Committee enquired as to why the

projected Transmission loss in the FY 2015-16 and 2016-17 were estimated as

3.64%. The Transmission loss were expected to come down on a Annual basis as is

estimated for the FY 2017-18 and 2018-19 which is 3.5% and 3.4% respectively.

Mr. Sharma replied that number of new projects are expected to come in the

operation only from FY 2017-18 and therefore loss is expected to remain the same

for FY 2015-16 and FY 2016-17.

b) Member Mrs. Susmita Priyadarshini enquired as to whether funds under North East

Region Power System Improvement Project (NERPSIP) are forthcoming which is

being used for strengthening and Augmentation of the existing network.

Mr. Sharma informed that the first Tranche of NERPSIP fund has been released

while the fund for the second Tranche is somewhat not firmed up and it is expected

that once this Tranche is received it can be used for augmentation of four Numbers

of 22KV Sub-Stations with Transformation capacity of 960 MVA and associated 206

Ckt Km of 220 KV lines and 120 Ckt Km of 132 KV lines.

iii) Representative from APDCL made a brief presentation on APDCL’s Business

Plan. The hard copy of the presentation was circulated among the members.

63

Agenda Item No 4:

Discussion and views of the members of the Advisory Committee on the Business

Plan 2016-19 submitted by the utilities.

A representative from TAIPA stated that the Business plan doesn’t suggest any

investment on Pre-paid meters. The collection efficiency of APDCL is around 92.87%

and stated that the company should devise a plan for installing prepaid meters in

industries to improve the Collection Efficiency. The member of the Committee

informed that there are around 6000 Tele-Communication Towers in the State and

TAIPA had approached APDCL to install Pre-paid meters in their towers. However,

the Company has not shown much interest on the proposal.

MD, APDCL informed that Pre-Paid meters were being installed in a phase manner

under RAPDRP Scheme.

The Commission observed that APDCL should take up the matter with TAIPA and

initiate process of installation of Pre-paid meters on Telecom towers on a priority

basis.

Mr. Dilip Kumar Baruah, Retd. Professor, Cotton College enquired regarding the

present Debt burden of APDCL and if there was any plan of the State Government

to take over the debt burden under the UDAY scheme.

APDCL explained that there is a Debt of around Rs. 1300 Crores and Government of

Assam has accepted the UDAY Scheme in principle. He further informed that the

decision will be taken on the issue of bonds etc. as per the scheme. MD APDCL

further informed that the Rs 1300 Crore are actually outstanding payments to be

made to the other utilities like NEEPCO, AEGCL and APGCL and there are no bank

debts as such.

There was a suggestion from a Mr. Arup Kumar Dutta, President; AASIA of the

Committee that APDCL should not give subsidized/free power to any category Govt.

establishment/consumers. It was clarified that power is supplied in bulk (single point)

to all consumers at the prevalent rate and there is no loss to APDCL .The subsidy is

given to certain consumers by Govt. and the entire cost of subsidy is borne by the

Government of Assam. It was also clarified that giving subsidised/free power is a

policy decision of the Government and APDCL is not giving subsidized power to any

consumer.

Mrs. Susmita Priyadarshini enquired as to how yearwise prediction of the

Electrification of new households is done by APDCL.

It was clarified by a representative of APDCL that the Data was taken from the GOI

power for all schemes and the Compounded annual growth rate (CAGR) have been

used to arrive at the numbers

64

Mrs Susmita Priyadarshini also enquired as to why the projection for the Distribution

loss in FY 2013-14 and 2014-15 remain same. While in other Fiscal Years the

projection graph shows at least a slight decrease in percentage of Distribution loss.

It was informed that there was massive Rural Electrification during the year 2013-14

and 2014-15 which resulted in higher Distribution Loss and therefore the projection

was shown same for both the years.

The Commission wanted to know to know whether APDCL is aware that once the

UDAY scheme is signed, there are certain standards of performance parameter

including AT & C loss which would have to be adhered to by APDCL.

MD APDCL informed that if the UDAY scheme have been signed all the Distribution

feeders, Distribution Transformers have to metered and AT & C loss have to be

restricted to 18%.

Dr. Birendra Kumar Das, President, Grahak Suraksha Sanstha, Guwahati enquired

as to the measures undertaken by APDCL to create consumer awareness.

APDCL informed that number of programmes have been undertaken to increase

awareness through radio, television, mobile theatre etc. on a number of issues like

electricity safety, use of energy efficient devices, theft of electricity etc.

Dr. Birendra Kumar Das also suggested that source of bill payments needs to be

improved further. He stated that the gap between bill delivery and bill payment is

sometime very less and the consumers have to face inconvenience while paying the

bills. He also suggested that there should be separate lines for payment for senior

citizens and ladies and priority should be assigned while making payment. Further,

he suggested that the number of washrooms should be increased in the collection

centres. It was informed that APDCL has introduced Kiosk in different Sub-divisions

in Guwahati and bills can also be paid through mobile and internet facilities.

Mr. Rohit Bajaj from IEX suggested that APDCL should buy power whenever

necessary from the Indian Energy Exchange as the cost of Power is much lesser

than the price of allotted power under long term agreement.

APDCL informed that they were buying power from the Energy Exchanges whenever

necessary. APDCL observed that although the price for allotted power and merchant

power is higher, even than APDCL chooses to continue buying from these sources

as the power availability is certain and APDCL avail advantage of a credit period for

the payment and also cost benefit analysis is done during the selection of power

purchase for allocated power also.

Mr. S. Baruah, President, NESSIA informed that they have written to the state

Government to decrease the VAT rate on LED lights to 5% from the present 14.5%

65

in order to reduce the price of LED bulbs and encourage more use of such bulbs by

the consumers which would help in reducing power consumption substantially.

The Commission requested Additional Chief Secretary Power GOA to take up the

matter of the reduction in VAT with Govt. of Assam.

Mr. Arup Kumar Dutta enquired regarding the smart Grid pilot project which is under

implementation by APDCL.

APDCL informed that works regarding this project has been taken up and although

the matter was delayed due to non-availability of vendors for smart meters, the issue

has now being resolved.

Agenda No. 5: Any other mater

No other matter had come up for discussion.

The meeting ended with a “Vote of Thanks” to and from the chair.
