ANNEXURE
- II
I. Installed capacity: Power suply position/peak deficit/energy
shortage.
1. The installed capacity as on 1st January 2000 both with KEB and KPTCL
is 4216 MW. Besides Karnataka has been allocated a share of 761 MW from
the central generating stations owned by NTPC, NLC, MAPP and Kaiga in
the Southern Region. In addition, the State has a captive generating capacity
of about 1600 MW mostly with large and medium size industrial consumers.
The hydel generating capacity constitutes 70% of the total generating
capacity of the State. The unrestricted peak demand of Karnataka is 4482
MW and average daily energy requirement of 78 MU per day.
2. With the installed capacity and share from the central generating
stations, Karnataka has met a peak demand of 4060 MW, and highest daily
consumption of 84.37 MU during January 2000, out of which hydel generation
is 36.44 MU, thermal generation is 24.65 MU, and 14.98 MU is supplied
from the Southern Regional Grid. In addition, Karnataka is presently importing
7.226 MU; of which MSEB supplies 2.998 MU and 2.784 MU is being received
from the Eastern region by utilising the HVDC link between Jeypore in
Orissa and Gajuwaka in Andhra Pradesh. M/s Jindal Tracteble is supplying
1.444 MU. Despite these arrangements which have been operationalised,
there is a shortage of 6.30 MU (average daily shortage).
3. At present there is no firm allocation of power to KPTCL from the
un-allocated capacity of central generating stations in the Eastern region.However,
KPTCL, has signed a PPA with NTPC on 3.12.1999 for purchase of 150 MWs
(3.75 MU) on a regular basis from the NTPC stations in Eastern region.
This allocation has been made out of the 600 MW capacity which has been
made available for constituent States in the Southern Region.
4. NTPC would require a LC to be opened amounting to Rs.15 crores per
month so that power could be supplied on an uninterrupted basis. This
amount has been assessed on the basis of an average rate of powr exported
from the Eastern region at 199 paise/Kwh. The pooled transmission losses
due to the power flow in the Easgtern Region has been assessed at 2.5%.
there is a subsisting agreement between constituents of the Southern Region
and POWERGRID for payment of transmission charges.
II. Additional Power to be made available to Karnataka
1. DVC has been allocated 393 MW from the Generating Stations operated
by NTPC in Eastern Region, of which 130 MW has already been surrendered.
The DBVC has adequate generating capacity of its own and, therefore, does
not require power from NTPC. Therefore, it will be possible to supply
100 MW of
power on a firm basis to Karnataka by NTPC. In view of the transmission
constraints which do not permit more power to flow from the Eastern region
to the Southern region, transfer of power can be effected by transmitting
power from Eastern Region to Northern region and thereafter, to Southern
region via the Western region. This would require co-ordination with
UPSEB/NREB. Member (G.O)/CEA, Sri V.V.R.K. Rao will work out the modalities
and the nature of agreements to be executed between NTPC/KPTCL/UP Power
Corporation/PSEB/PGCIL. This would also require KPTCL to open an additional
L/C of about Rs.15 crores per month in favour of NTPC.
2. Karnataka has been allocated a share of 84 MW from NLC Stage-II Mine
cut-I and 115 MW from Mine cut-II. There is an unallocated share
of 220 MW out of which constituents are allocated by CEA. CEA would allocate
an additional 80 MW in addition to the existing allocation. This would
enable Karnataka to get an additional 2 MU per day from NLC. An agreement
has to be executed between NLC and KPTCL for which CEA will have to play
a facilitating role.
III. Transmission Systems to be taken up by POWERGRID
1. Karnataka Power Transmission Corporation Ltd. Has suggested several
transmission schemes to be taken by POWERGRID, in order to strengthen
and improve the reliability of the State transmission system and also
to enable surplus power to flow from both the Eastern and Western regions.
Some of these lines have already been taken up by POWERGRID and are under
execution:-
a) Establishment of Kolar HVDC substation
b) Talcher-Kolar HVDC bipole for receiving 2000 MW from Talcher
for
benefit to the constituent States in the Southern region.
c) Kaiga-Narendra (Dharwad District) 40 KV D/c lines to evacuate power
from Kaiga Atomic Power Station (440 MW) to North Karnataka.
2. Some of the lines are proposed for enabling transfer of power from
Maharashtra on a long term basis. A pre-feasibility report will be jointly
prepared by POWERGRID and KPTCL in consultation with MSEB, POWERGRID
would
take up the construction of lines after approval of CEA, and after the
commercial agreements have been executed. The transmission charges would
have to be borne by KPTCL. These lines would include:-
a) Kolhapaur-Mahalingapur-Narendra 400 KV D/c line along with construction
of 400 KV substations at Narendra in Dharwad District and Mahalingapur
in Bagalkot District.
b) Parli-Hymnabad 400 KV D/c line.
3. The third category includes lines which would benefit Karnataka as
well as
other constituents in the Southern region. A pre-feasibility report will
be prepared jointly by KPTCL and POWERGRID and there after necessary approvals
would be obtained from SREB and CEA. Once these lines are approved as
regional lines, it would be possible for POWERGRID to organise the finances
and undertake construction. Thereafter, the recovery of fixed monthly
transmission charges from the constituent States of Southern region will
be done by POWERGRID. The lines proposed to be taken up under this dispensation
are:-
a) Raichur-gooty 400 KV S/c line.
b) Nelamangla Mysore 400 KV D/c line.
4. Efforts will be made to complete the lines envisaged in the next 2-3years.
IV. Strengthening of the Sub-transmission and Distribution System
in
Karnataka.
1. A new scheme has been formulated by Planning Commission in consultation
with Ministry of Powr to be implemented with effect from 1-04-2000. Under
this scheme Karnataka along with other reforming States would receive
funds for (I) Renovation and Modernisation (R&M) and Extension/uprating
of the generating stations (both thermal and hydel); and (ii) strengthening/upgrading/improvement
of the distribution system including sub-transmission. In order to derive
maximum advantage from this scheme which provides for both grant and loan
to be given by the Planning Commission as well as loan by PFC/REC, it
would be necessary for Karnataka to prioritize the investments required
to undertaken both in urban as well as rural areaas so that the entire
State couldbe covered in a phased manner. In the first phase of the programme,
Karnataka will cover all cities (population > 5 lakhs, 1991 census)
including adjoining rural areas. The investments that could be funded
would include (I) Conversion of LT lines to HT lines, (ii) augmentation
of transformer capacity, (iii) installation of capacitors at 33 KV, 66
KV and 110 KV substations for providing reactive compensation. This is
necessary for improving the voltage profile, (iv) introduction of metering
arrangements at major sub-stations and at the premises of bulk consumers
and (v) other system improvement schemes.
V. Reduction in T&D Losses.
1. The line losses in different parts of the country based on the actual
studies carried out are in the range of 15 to 20%, and power factor is
in the range of 0.7 to 0.8. These have resulted in high voltage drop at
the consumer end and a typical consumer in the rural area has a voltage
drop between 60 to 100 Volts. By converting the extremely long 440 Volt
lines to 11 KV lines, losses can be substantially reduced. Under this
project the poles, conductors can be reused and only the insulators, cross
arms and transformers are required to be modified. The transformers will
be of smaller size (10 to 25 KVA) and these will be erected as close to
the load centres as possible. Typically, in Haryana every farmer has been
given one transformer and in case of A.P. where there are a number of
pumps two or three pumps have been clubbed together with one transformer.
Along with transformers, the capacitors have also to be installed so that
power factor correction is achieved. This also enables capacitors to go
on-line when the load is on line and switched off when load is switched
off. Additionally, for load management purpose alternate technologies
are available. Transformers can be disconnected at different times for
necessary required duration to distribute the shortage in an equitable
and technically acceptable manner. The investment required will be approximately
Rs. One crore per feeder. A district has about 100 feeders and, therefore,
Rs.100 crores would be required per District. To evaluate the scheme and
to quantify the benefits it would be desirable to select two district
which are badly affected by low voltage and line losses. Thereafter, based
on the actual results monitored after the implementation the remaining
districts can be taken up in phased manner. A feasibility study has to
be carried out in the two selected districts to chose the most appropriate
system of HVDS taking into account the local constraints. Once the feasibility
is established, a detailed project report will have to be prepared with
all the technical specifications, requirement of equipment, modification
of the system and time frame in which the entire project would be completed.
The implementation of the project will be funded by the Energy Conservation
revolving fund through a loan at about 7% interest. The repayment period
will be seven years, including two years moratorium.
2. The problem of T&D losses including theft can be substantially
solved by taking up following activities treating a sub-station as an
unit.
a) Installation of pre-paid electronic meter/electronic meters at the
sub-station.
b) Conversion of LT line to HT line within the area served by the sub_station.
c) Installation of capactors to improve the power factor at the sub-station.
d) Upgradation/replacement of transformers.
e) Installation of electronic meters on all the consumers lined to high-tension
line and the domestic consumers.
The above activities/retrofitting will bring down the T&D losses
(including theft and pilferage) in the areas served by the sub-station
by 10 to 15% if not more.
3. In athe rural S/S areas the above activities can be combined with
a programme of replacement/rectification of the agricultural pumpsets
including replacement of suction & delivery water pipes. A large number
of studies have proved that replacement of existing low efficiency pumpsets
with high efficiency pumpsets and replacement of GI suction & delivery
pipes with PVC pipes would refuce electricity consumption straightway
by 30 to 35%. Therefore, a combination of rectificaiton/replacement of
pumpsets & water distribution pipes and all the activities to reduce
T&D losses (including theft and pilferage) as mentioned above, would
cumulatively reduce powr consumption in the Sub-station area by 25 to
30% which could easily pay for the investment made in the retrofittings/installation
in a short span of time.
4. Similar arraangement can be worked out in the urban areas where instead
of replacements/rectification of agricultural pumpsets, energy efficiency
in all the major institutional/commercial buildings, water-pumping systems
and in the process industries together with reduction in T&D (including
theft) losses, would make it possible to get substantial saving in energy
conservation. We need to make attempts in both rural and urban areas.
5. It is agreed to create certain demonstrations using funds from PFC/REC/FIs.
To begin with, it is agreed to take up energy audit of few urban and rural
sub-stations in some districts in Karnataka. The energy audit conducted
on lines discussed above will bring about the total investment required
in retrofitting and possible savings in energy sub-station-wise. The costs
of taking up energy audit and associated activity be funded by the Central
Government.
V. Concessional Lending from PFC for Sub-Transmission System
1. Under the Accelerated Generation Programme 9AGSP), PFC had extended
concessional lending for some of the programmes of the KPTCL with an interest
rate of 9 to 10%. The concessional lending is available for 400 KV transmission
line from Shmoga to Nelamangala, Metering, Capacitor Banks. R&M of
Shivasamudram/Jog. Other proposals for 220 KV Sub-stations and transmission
lines of 110/66 KV have been posed to the PFC for concessional lending.
PFC would consider this expeditiously.
2. PFC will also consider suitable finding of KPTCLs future plans
for automation and SCADA covering.
· Expansion of VSATS to cover new generating ans sub-stations,
Zonal and Circle offices where video conferencing is also proposed with
these offices. (Total cost Rs.10 crores).
· Expansion of SCADA It is proposed to extend the SCADA
system in the State and to have a separate SCADA system for Bangalore.
(Total cost Rs.35 crores).
· Expansion of Computerised billing and collection and other packages
in 258 sub-divisions, 58 Division offices, 10 Circle offices and 5 Zonal
offices besides other offices in the State (Total cost Rs.51 crores).
· Remote reading of meters in Sub-stations: In order to hve a
proposer accounting of energy transmitted from sub-stations and sold to
the consumers. It is proposed to have remote reading of meters in sub-stations
for the purpose of energy auditing. For this, it is proposed to install
PCs in each of the sub-stations and associated equipment. (Total cost
Rs.18 crores).
· Hand Held Instruments for Meter Reading: In order to effectively
read meters of consumers without any error, it is propsoed to provide
hand held instruments to all the meter readers in the State. The readings
recorded in these instruments will be down loaded onto the PCs in Sub-divisions.
(Total cost Rs.7.5 crores).
· Access Control: In order to monitor the movement of staff in
major offices, it is proposed to introduce multi purpose SMART Cards.
3. Under the commitment made by Govt. of Karnataka to PFC for reforming
the power Sector, PFC will provide the following assistance linked to
milestones of Reforms. (R-OFAP).
a) Financial Assistance:
· Comprehensive package of financial assistance and support of
the investment plan in relaxation of the current policy in regard to exposure
limit, for considering sanction.
· Relaxation in eligibility conditions for State Utilities on
ROR, DSCR etc.
· Extent of funding for all types of projects to be 80% of the
cost of the project as against lower percentage for different schemes
as at present.
· Provide concessional lending for selected projects.
· New private utilities formed as a result of reform process,
also be considered for funding.
· Providing support to the financial restructuring plan recommended
by reform studies and agreed to by lenders.
b) Grant/Soft Loans studies Technical Assistance:
· Grants to carry out reform related and other studies.
· Interest free loans/soft loans provided for studies.
· Grant offered to SERCs for procurement of computers and accessories,
conducting reform related studies, seminars and workshops.
c) Technical Assistance:
· Assisting States in finalising Terms of Reference, bidding,
evaluation and selection of consultants for carrying out reform related
studies.
· Support institutional strengthening of utilities in areas like
computerisation/communication, improvements in metering, billing and collection;
distribution management; DSM load growth demand patter; tariff reationalisation
etc.,
· Conducting workshops/seminars and training programmes on reform
and regulation.
VI. Rural Electrification Plan Programme
1. In Karnataka, Govt./KPTCL intends to electrify all the balance hamlets/villages
in the State (by the end of the year 2004-05). Un-electrified hamlets
as on date are 17,933 and villages to be covered are 52. The programme
for 1999-2000 is 3,600 hamlets and the few un-electrified villages. The
programme will cost approximately Rs.77 Crs. The REC is presently funding
KPTCL for the electrification of villages and hamlets. REC funding will
be available for the programme. However the rate of interest charged by
REC is high considering the fact that most of the uncovered villages and
hamlets are located at far flung area located at a considerable distance
from the main grid, therefore, the investments ae not remunerative. Hence,
REC need to provide loans for electrification of hamlets/villages at a
concessional rate of interest.
2. REC has a Kutir Jyoti Programme with a grant of Rs.800/- per connection
without meter. KPTCL is availing funds from REC. it is necessary to integrate
the electrification of hamlets and villages in the state so that grant
component can be enhanced and metering facility is provided for all connections
even though no billing is involved. REC also may fund projects on a subsidised
basis for establishing this sub-transmission network to supply electricity
to the Rural areas and to undertake electrification of un-electrified
villages.
