ANNUAL PLAN AT A GLANCE

The annual plan outlay for the last 10 years and for the year for 2009-10 under State Plan is

highlighted below:-

Salient features of Annual Plan 2009-10 is given below:

1. The total outlay during 2009-10 is 40.6% increase over 2008-09 only. However, the actual re-

quirement during 2009-10 for continuation of on-going developmental works is much higher than the

projected outlay.

2. The projected outlay can be divided as follows:-

(Rupees in lakhs)

3. Direction & Administration : There are 178 nos of Plan posts which had not yet been con-

verted into non-plan posts. The establishment cost of these 178 posts continues to be met from plan

fund. In addition to the above, there are many infrastructural assets created since 7th Five Year Plan.

The maintenance of many of these assets is still met from plan fund as the same are not yet committed

to non-plan. At the same time, the Department underwent expansion last year, during which 35 nos of

posts, mainly those in the top structure, were created. Hence, the fund requirement for maintenance of

Direction & Administration, including wages of MR and W/C staff, Office contingency, Motor vehicle

.. etc is worked out to be Rs 2,806.00 lakhs. For wages of 2123nos of MR and 625 nos of W/C staff

in the Department, the amounts of Rs 1038.84 lakh and Rs 781.16 lakh respectively are provided

16


initially in this Plan. However, due to revision of M.R wages vide No.B.11015/1/2009-L&E dt.3.11.09

additional fund was required for which proposal was submitted to Government for additional alloca-

tion. Accordingly, additional allocation amounting to Rs 317 lakhs was made vide No.G.20015/1/

2010-FBT dt.1.3.2010.

4. Works: The works component may be grouped as follows:

Un-earmarked:

(1) Generation: Mizoram is not having its own power generation except from few mini hydel

projects which are seasonal, and operational during rainy season. Though a number of me-

dium and major projects of hydel generation are in the pipeline, harnessing of the hydel

potential can not be taken up in a big way due to fund constraint. Recently, Maicham-II Mini

Hydel Project of 3MW capacity and Lamsial Mini Hydel Project of 500kW were com-

pleted and commissioned. Serlui 'B' Small Hydel Project of 12MW capacity is also at comple-

tion stage under the State sector. In addition to this, Renovation & Modernisation of the old

mini hydel projects of Tuipui, Serlui 'A' and Khawiva are completed which now supplements

the power availability to some extent during rainy season. In spite of the fund constraints, it

is important that we should strive towards harnessing of the immense hydel potential, with

which Mizoram is endowed. So, in this year's Annual Plan, an amount of Rs 10.0 lakh is

provided under Hydel generation for investigation purpose.

Again, under Hydel Generation (R&M), a fund of Rs 9.40 lakh is provided for

repair of Penstock at Serlui 'A' Micro Hydel Station, to complete the R&M work financially.

(2) Transmission: The transmission network within Mizoram is so far at 132kV and at 33kV

levels. The overall sizes of the network are as follows:

(i) Transmission lines at 132kV level - 638.37 Km

(a) Charged at 132kV - 203.98 Km

(b) Charged at 33kV - 434.39 Km

(c) 66kV charged at 33kV - 117.00 Km

(ii) Sub-Transmission lines at 33kV level - 828.03 Km

There is a plan now under active consideration to bring into the State 400kV level

transmission system, to strengthen the power network, keeping in view future plan of gen-

eration and power transaction in the State. At the same time, the collapsing 132kV Sub-

Station at Zuangtui due to massive hill slide, necessitate re-drawing of 132kV power net-

work in the central part of the State, which involves re-alignments or new construction of

132kV lines and Sub-Stations. In spite of these huge tasks ahead, an amount of Rs 34.95

lakh only can be provided innitially in this Annual Plan due to inadequacy of available fund.

The Plan targeted re-alignments / improvements of existing 132kV and 33kV lines including

some new constructions, to remove network constraints and to complete on-going projects.

In addition to above, Government of Mizoram had made additional allocation ot the

tune of Rs 200 lakhs and Rs 1050 lakhs for Construction of 33kV D/C Serlui B to Bawktlang

line and Equity share of 400kV Palatana to Bongaigoan line vide No.G.20015/1/2010-FBT

dt.1.3.2010.

(3) Transformation: In general, the present transformation capacity at 132/33kV and 33/11kV

levels requires strengthening to cope up with the increasing power demands. At the same

time, the capacity addition Plan in the Generation and Transmission fields also calls for the

corresponding strengthening of transformation capacity at various Sub-Stations and at vari-

ous on-going Projects. At present, it is proposed to construct 1x25.0MVA, 400/132kV

17


Sub-Station at Sihhmui to draw power at 400kV level when the 400kV Srikona (Silchar) -

Aizawl line is completed by PowerGrid. However, the transformation capacity in existence

at present are as below:-

(i) Sub-Station at 132/66kV, 132/33kV, 66/33kV

& 11/132kV level - 7 Nos (153.20 MVA)

(ii) Sub-Station at 33/11kV level - 43 Nos (187.90 MVA)

(Inclusive of 33/11kV system at 132 kV Sub-Stations)

(4) Distribution: At present, the size of Distribution network under the Department is as follows:

(a) 11kV lines - 4292.41 Km

(b) Distribution Sub-stations (DTs) - 1273 Nos. (179.35 MVA)

(c) LT (low tension) llines - 2251.97 Km.

In almost all the villages, towns / City of Mizoram, there is growth. Villages are growing

bigger and towns are expanding due to imigration. Inhabited areas are increasing with popu-

lation increase and new constructions. These growths call for massive strengthening of Dis-

tribution networks, involving the need for new 11kV lines, new distribution transformers

(DTs), and new LT lines. In many areas, the need is in the form of extensions or strengthen-

ing, or augmentation to bring the benefits of electricity to more people or to wider areas, or

to improve the quality of the electricity, as against the low voltage regulation due to voltage

drop. In many cases, the strengthening is required in the form of augmentation of the distri-

bution lines or transformers which have become undersized on account of increase in de-

mands from the areas they cater. The overall practical need of new infrastructures for distri-

bution network is also huge and immense this year. But due to the overall fund shortage, an

amount of Rs 295.91 lakh only can be provided for Distribution work. The provided fund

mainly targeted completion of on-going distribution works, such as Raising of DT Platforms,

renovation of 33kV and DT Sub-Stations, Repair of damaged DTs, Wireless, metering of

Circle inputs ..etc.

(5) Buildings: In spite of numerous Department's residential and non-residential buildings acutely

due for repair, and the necessity to continue construction of RCC buildings for 33kV Indoor

Sub-Station, for the Office of the E-in-C, P&E at P&E Office Complex, Electric veng,

Aizawl, including the need to improve the Complex, no fund more than Rs 46.74 lakh can be

provided due to shortage.

Earmarked:

(6) Additional Central Assistance (ACA):

(i) Replacement of existing LT bare Conductors at Aizawl and at Lunglei by Insulated

Aerial Bunched Cables - Rs 513.36 lakh

(ii) R&M of 22.92MW HFO based standby Diesel Generating sets- Rs 250.0 lakh

(iii) Construction of 2x3.50MVA, 33/11kV Sub-Station at P&E Complex, Lunglei,

with the 9.0km 33kV D/C line Khawiva - Lunglei - Rs 622.47 lakh

(iv) Renovation of 132KV Sub-Station at Khawiva, Lunglei - Rs 298.0 lakh

(v) Installation of Optical Ground Wire (OPGW) in 132kV Aizawl - Lunglei line

- Rs 719.0 lakh

(vi) Upgradation of 33kV Sub-Station, Bilkhawthlir - Rs 215.0 lakh

(vii) Construction of 33kV Sub-Station at S. Vanlaiphai, including the associated

33kV and 11kV line - Rs 300.0 lakh.

18


(viii)5.0 Km 33kV D/C Mualpui - Tlangnuam line - Rs 200.01 lakh

(ix) Augmentation of 132kV Sub-Station, Luangmual - Rs 74.16 lakh

(x) Improvement of 132kV Sub-Station, Bawktlang, Kolasib - Rs 395.0 lakh

Total :Rs 3587.0 lakh

5. Non-Conventional Source of Energy (NCSE): For Non-Conventional Source of Energy Rs

50.00 lakhs is provided during 2009-10 for taking up non-conventional system of energy sources. This

fund will be transferred to Zoram Energy Development Agency (ZEDA), an autonomous body and

nodal agency for non-conventional sources of energy in Mizoram as Grant-in-Aid.

6. Integrated Rural Electric Programme (IREP): Under this scheme Rs 11.00 lakhs is provided

during 2009-10 and similar to above, the fund will be transferred to ZEDA as Grant-in-Aid.

CONCLUSION: Approved Annual Plan 2009 - 10 Rs 6911 lakhs is framed based on the direc-

tion of State Planning Board, Government of Mizoram vide their letter No. G.28014/55/2009-10/

SPB/Pt-III dt. 22.07.2009 and No. G.28014/55/2008-10/SPB dt. 19.8.2009.
