PETITION UNDER SECTION 23 OF THE ELECTRICITY ACT, 2003 SEEKING
REGULATORY GUIDANCE FOR MEASURES TO BE TAKEN IN CASE OF EXIGENCIES
LEADING TO POWER CUTS FOR THE TARIFF YEAR 2019-20.
MOST RESPECTFULLY SHOWETH:
1. The present petition is being filed by the Petitioner, Punjab State Power
Corporation Limited (hereinafter called PSPCL) under Section 23 of the
Electricity Act, 2003 seeking regulatory guidance and concurrence of the
Hon'ble Commission for the measures to be taken by PSPCL for load
regulation and imposing power cuts in case of exigencies and system
requirements.
2. PSPCL is hereby providing the basis, assumptions and projections of the
elements constituting the determination of demand/Supply gap, the
prevalent regulations being undertaken and their constraints, the extent of
power regulatory measures required to be imposed on various categories
of consumers in an equitable manner with an objective of ensuring quality
power in the most economical and reliable manner and in compliant to
National/State grid code during the year 2019-20.
1
2--d8b1-d774-48d4-b185 3/1/2019
3. The endeavor of PSPCL as a distribution licensee is to ensure uninterrupted
power supply to all its consumers and regulate the supply only in case of
unavoidable exigencies. After incorporating the latest anticipated banking
arrangements for the period FY-2019-20, the details of the anticipated
demand and availability of electricity for the year 2019-20 is provided in
the attachment marked as Annexure A.
4. PSPCL is presently expected to be surplus in power availability for the year
during 2019-20. The details of the applicable category of feeders - PR
Circular 5/2003 dated 05.06.2003 is attached hereto and marked as
Annexure B.
5. It is stated that from the details in Annexure-A, it is evident that there
would be a surplus availability of electricity to PSPCL during the year 2019-
20. In the circumstances, it is expected that the requirement to regulate
supply to consumers and imposing power cuts would be minimal and only
to take care of unexpected events and circumstances.
6. It is pertinent to mention that post grid collapse of 30 & 31.7.2012, the
stringent grid regulations are applicable for deviation from the schedule
which includes severe penalties in terms of high deviation charges. The
availability of power has to be maintained around the running load at all
the times for safeguard of the grid.
7. With the introduction of capping on volume limits on over drwal from the
grid in the currently applicable deviation settlement mechanism, the
violations beyond the specified limit attract severe penalties against over
drawl from the system in real time operation as such the regulation of load
through the implementation of the power regulatory measures may be
necessitated on real time basis. Moreover, after applicability of new DSM
2
3--d8b1-d774-48d4-b185 3/1/2019
regulation 2018 w.e.f 1.1.2019, the frequency band has now become 49.85
to 50.05 HZ which was earlier 49.70 to 50.10 HZ. By linking market clearing
price of exchange with the DSM rate, the operation of power system on
day to day basis has become more rigid and in case of sudden outages of
power system elements, the power regulation may be the utmost
requirement in the interest of safety of grid.
8. It is however stated that even in the surplus scenario, the eventualities as
mentioned below cannot be ruled out in the power system which may
require regulation of load and supply:
Till now, all the three no. IPPs viz NPL, Rajpura (2x700=1400 MW),
TSPL, Talwandi Sabo (3x660 = 1980 MW) & GVK, Goindwal Thermal
plant (2x270=540 MW) have been synchronized with the grid. The
forced outage of the generating units especially these larger capacity
IPPs for longer duration may necessitate the imposition of regulatory
measures on the consumers.
Any downward revision in the Central Sector schedule due to longer
duration on account of forced outage of Central Sector Generating
Units, in which the State of Punjab has a major stake.
A maximum unrestricted demand of 2750 LUs on 4.8.2018 and a
peak demand of 12638 MW have been recorded during the year
2018-19 on 10.7.2018 without imposing any notified regulatory
measures/power cuts. During the year 2019-20, a projected
unrestricted demand of around 13500 MW is being envisaged. With
a full internal generation and any forced outage due to any
unforeseen reasons & any limitation of the transmission/ sub
3
4--d8b1-d774-48d4-b185 3/1/2019
transmission network, may necessitate imposition of Regulatory
Measures.
At present, the existing ATC/ TTC of Punjab has been fixed by NRLDC
as 6400 / 7000 MW respectively (Annexure-C). With any reduction
of internal generation due to forced outage may require the
emergent imposition of Power Regulatory Measures during the year
2019-20 to keep the system running within the limitations of grid
code.
Any restrictions due to overloading of inter-regional lines may also
necessitate load shedding within the state.
In addition, the scheduled commissioning of the new generating
units i.e. Parbati-II (80 MW share) and Tapovan Vishnugadh (41 MW
share) Hydro electric plants under the central sector may also get
delayed and the energy which is envisaged to remain available
during the year 2019-20 become uncertain, on account of which
situations may arise for the imposition of power regulatory
measures.
Any other contingency, where availability of power is not able to
meet with the demand may also be required in regulating the load
on the system on real time basis.
9. In the scenarios and circumstances as mentioned above, PSPCL may be
required to bridge the demand / supply gap within Punjab control area on
real time basis by imposing various regulatory measures.
10. Under the Electricity Act, 2003 while the management of load is to be taken
care of by the licensees, a provision in Section 23 enables the Hon'ble
Commission to decide the principles and basis on which the regulation in
4
5--d8b1-d774-48d4-b185 3/1/2019
power can be done, to the extent possible in case of exigencies and
circumstances that may arise. Further, having a guiding principle for
imposing regulatory measures in case of exigencies result in greater
regulatory certainty.
11. In the circumstances mentioned above, PSPCL proposes the following
regulatory measures to be taken in case it becomes imperative to impose
power regulatory measures and impose power cuts:
To regulate the supply by imposing power cut on feeders controlling
supply to the 24 hours UPS/Urban-Industrial Cat-1/Main cities /
District. Head Quarters.
To impose weekly off day(s) on LS & MS category of industrial
consumers fed from category 2 & 3 industrial feeders.
To restrict the drawl of the LS & MS category consumers (fed from
category 2&3 feeders) to the extent required for keeping the system
running within the grid code limitations during peak load hours as
well as off-peak hours.
To restrict the drawl of power by continuous process (category 4)
consumers to the extent of their continuous process load allowed to
them during peak/ off peak load hours, as per the policy approved by
the Hon'ble PSERC.
To regulate power supply to AP consumers.
Any other additional regulatory measures to the left out category of
consumers in case of exigencies of outage of own / central sector
5
6--d8b1-d774-48d4-b185 3/1/2019
generating units or transmission/ sub transmission network of ISTS/
STU or any of the major grid elements ICTs etc.
The priority order of imposing power cuts/regulatory measures
generally be followed as:
Priority Order for Regulation of
Power Supply to various
categories of consumers.
Type of Regulatory Measure
1 AP Feeders Power Cut (opening of Breakers from the Grid
Substations for certain period in rotation
depending on the requirement in real time) for
safeguard of grid. Thereafter, all possible efforts
will be made to compensate the AP supply
within 24 Hrs.
2 Kandi feeders / UPS Feeders
Power Cut (opening of Breakers from the Grid
Substations for certain period in rotation
depending on the requirement in real time)
3 Category-1 feeders
Power Cut (opening of Breakers from the Grid
Substations for certain period in rotation
depending on the requirement in real time)
4 Category-2 feeders Restricting the drawl of the LS & MS category
consumers to the extent required for keeping
the system running within grid code limitations
/ Imposing Weekly-Off Day on LS & MS
Category consumers.
5 Category-3 feeders Restricting the drawl of the LS & MS category
6
7--d8b1-d774-48d4-b185 3/1/2019
consumers to the extent required for keeping
the system running within grid code limitations
/ Imposing Weekly-Off Day on LS & MS
Category consumers.
6 Category-4 feeders feeding
continuous process status
industrial consumers.
To restrict the drawl of power by Continuous
process consumers to the extent of their
continuous process load allowed to them
during peak/off-peak load hours.
Note: Depending upon the Real Time Requirements, Various Permutation &
Combinations may be used for bridging the gap in demand & supply owing to
various exigencies explained above till some alternate arrangement is made.
12. It is stated that in the year 2019-20, the regulatory measures shall be
imposed on the real time basis depending upon the real time gap in the
demand and supply of power and other system constraints.
13. PSPCL shall however make its best endeavor not to impose any regulatory
measures and shall on its part:
(a) Impose minimum Scheduled Power Regulatory Measures /
Scheduled Power cuts for which an advanced notification will be
published about the schedule of power cuts and regulatory
measures in case of outages/exigencies for longer durations without
any scope of alternate arrangement of power.
(b) Unscheduled load shedding, if any, shall only be imposed during
sudden outage of generating units or exigencies in the grid. Duration
of such load shedding shall be kept to be as minimum as possible.
7
8--d8b1-d774-48d4-b185 3/1/2019
14. The Hon'ble Commission had for the year 2018-19 passed orders dated
4.5.2018 against Petition No. 06 of 2018 dealing with the regulatory
measures to be taken when situation arises. The said order dated 4.5.18 is
effective for the period till 31.03.2019.
PRAYER:-
In the facts and circumstances mentioned above, it is respectfully prayed
that the Hon'ble Commission may be pleased to:
(a) Admit and take on record the present petition filed by PSPCL on the
regulatory measures proposed to be taken for the purpose of
maintaining equitable distribution of power supply throughout the
State of Punjab and to operate the grid in a most economical and
efficient manner in compliance to the IEGC/State Grid Code
Provisions.
(b) Provide guidance on the regulatory measures proposed by PSPCL as
detailed hereinabove and make such modifications in the proposal of

e When generation at Lehrarylohabbat is reduced, then loading of lrloga lCTs increases bY
significanfrnargin, loading of lCTs at Ludhiana also i!'rcreases by consiclerahle margin. Thus, full
generation at !-ehramohabbat is necessary to maintain this ATC/TTC limit fcr Funjab.
o lVlore generation at Goindwal TPS woulcj only help to reduce constraints at Amritsar, IVlakhu iCTs
and underlying network. Thus, Punj,ab SLDC shall try to maximize generation at Goindwal TPS so
as to reduce loadings of Amritsar lCTs and underlying network.

Punjab SLDC needs to rnclnitor continuorisiy the voltage profile, load power factor and avallabilityof shunt con'lpensation. Punjab Pianning division/ SLDC has to reass€ss its irnpori capabitrity forany change in the Punjab control area frorn the assurrred scenario.
Based on above TTC/ATC computation and latest LTA/allocation details provided by pun.!ab {pSpCL},
