6. DIFFERENCE IN COMPUTATION OF CAPACITY CHARGES OF NTPC STATIONS AS PER NEW CERC REGULATIONS (2014-19)

6.1 KSEB vide letter dated 14th July 2014 (Annexure-IX) had proposed the following

point for discussion in the 24th TCC/ 25th CRPC Meetings:

Reference has been invited to CERC Tariff Regulation 2014-19 regarding

payment of capacity charges to Thermal Generating Station for a calendar

month. It has been stated that all generators have adopted calculation

procedure in accordance with CERC Norms whereas NTPC has adopted a

different methodology for the same. The amount claimed towards capacity

charges by NTPC is more than the amount permissible as per CERC

Norms.

6.2 In the 24th Meeting of TCC held on 25th July 2014, it had been agreed that the issue

would be first discussed in the Commercial Sub-Committee.

6.3 In the Meeting, KSEB stated that in accordance with Regulation 30 (1) of CERC

Tariff Regulations 2014-19, fixed cost of a thermal generating station shall be

computed on annual basis, and recovered on monthly basis under capacity charge.


Total capacity charge payable for a generating station shall be shared by its

beneficiaries as per their respective percentage share / allocation in the capacity of

the generating station. Regulation 30 (2) details the manner in which the capacity

charge payable to a thermal generating station for a calendar month shall be

calculated. The prorata Annual Fixed charges up to the last day of each calendar

month is to be recovered fully if the cumulative Plant Availability Factor achieved

upto the end of the calendar month is equal to or more than Normative Annual

Plant Availability Factor. If the cumulative Plant Availability Factor is less than

Normative Annual Plant Availability Factor, the cumulative monthly capacity charge

up to the end of the calendar month would be reduced proportionally. Capacity

Charge for a month would be calculated by deducting the Cumulative Capacity

Charges recovered till previous month from the Cumulative Capacity Charge up to

the end of the billing month. Further, as per Regulation 42 (2), payment of the

capacity charge for a thermal generating station shall be shared by the

beneficiaries of the generating station as per their percentage shares for the

month (inclusive of any allocation out of the unallocated capacity) in the installed

capacity of the generating station.

KSEB further stated that NTPC is apportioning the cumulative annual fixed charges

up to the last day of each calendar month among the beneficiaries of the

generating station based on the cumulative percentage allocation up to the end of

the month. From this figure, the cumulative capacity charges paid by the respective

beneficiary till previous month are deducted to arrive the capacity charge for the

month. The methodology being followed by NTPC is against the true spirit of the

Regulation.

6.4 NTPC first of all clarified that annual capacity charges being claimed by NTPC

were strictly as per the approved tariff by CERC and hence these were not

more than the amount permissible as per CERC norms. All beneficiaries

including KSEB agreed to this. NTPC further stated that the computation and

billing of capacity charges etc. being carried out was in line with CERC Tariff

Regulations 2014-19. Cumulative Capacity charges payable by a beneficiary is

computed based on the cumulative allocation percentage up to the month and

after deducting the capacity charges paid up to the previous month, the

capacity charges payable for the month is arrived. This methodology had been

in vogue since the introduction of two part tariff by GoI in 1992 and upto the

tariff period 2004-09. During the tariff period 2009-14, there was change in

methodology of computation of capacity charges from cumulative to monthly

basis which has been again changed to cumulative basis in 2014-19

Regulations.


6.5 After deliberations, all other beneficiaries, except KSEB were agreeable for the

methodology currently being followed by NTPC.

7. DRAWAL POINTS OF COASTAL ENERGEN

7.1 SRPC Secretariat vide letter dated 15th July 2014 (Annexure-X) had sought

views/comments from the Members on the issue of energy accounting of drawal by

Coastal Energen. It was proposed that energy accounting of drawal by Coastal

Energen be based on the meters at Madurai end on Madurai-Coastal line and

meters at Coastal end on Coastal-NTPL line.

7.2 NLC vide letter dated 17th July 2014 (Annexure-XI) had stated that energy

accounting of startup power drawal by NTPL be based on the energy meters

provided at NTPL end of 400 kV NTPL – Madurai & 400 kV NTPL- Coastal lines.

7.3 Coastal Energen vide letter dated 17th July 2014 (Annexure-XII) requested to

consider metering point for 400 kV Madurai – Coastal Energen line at Coastal

Energen end.

7.4 After deliberations, it was agreed that energy accounting of drawal by Coastal

Energen be based on the meters at Madurai end on Madurai-Coastal line and

meters at Coastal end on Coastal-NTPL line. It was also noted that energy

accounting of startup power drawl by NTPL would be based on the energy meters

provided at NTPL end.

8. PENDING ARREARS PAYMENT BETWEEN BENEFICIARY STATES IN SR

8.1 TANTRANSCO vide letter dated 11th August 2014 (Annexure-XIII) had proposed

discussions on the issue of pending payment between TANTRANSCO and PCKL

12.1 In the 98th Meeting of OCC of SRPC held on 12th August 2014, SRLDC had

informed that in Eastern Region allocation of URS power to the beneficiaries was

being carried out by the Generators. SRLDC had stated that as per Hon’ble CERC

order dated 11.01.2010 in Petition No.134/2009 with I.A. No.54/2009 allocating of

Un-requisitioned surplus (URS) Power of ISG Stations could be carried out by the

Generator itself.

12.2 After deliberations, OCC had suggested that the matter be discussed in the

Commercial Sub-Committee Meeting. In this connection relevant pages from the

Minutes of the 99th Meeting of OCC of ERPC is enclosed as Annexure-XV

12.3 In the Meeting, SRLDC stated that in line with CERC order dated 11.01.2010,

12.4 SRPC Secretariat pointed out that as per CERC order dated 11.01.2010 in Petition

No. 134/2009 with I. A. No. 54/2009, all the generating stations, governed by the

Tariff Regulations of the Commission are allowed to change schedule for the

unrequisitioned quantum of power from one beneficiary(s) to another beneficiary(s)

of the same power station on the requisition by these beneficiaries through the

provision provided in the IEGC. These schedule revisions would be treated as re-

allocation of power on temporary basis and would not be taken as open access

transactions.

As per IEGC, ISGS shall advise the concerned RLDC, the ex-power plant

capabilities. Based on the capability declared by the ISGS, RLDC would

communicate the entitlement to each beneficiary. RLDC would convey the

Generation Schedule of ISGS based on the requisition received from the

beneficiaries. The responsibility of ISGS is to declare the plant capabilities faithfully

i.e, according to their best assessment and power generation/injection according to

the schedules advised by the RLDC. As such, URS power had to be allocated /

scheduled by SRLDC to the beneficiaries based on their requisition.


12.5 NTPC appreciated the efforts of SRLDC in scheduling the URS power in the past.

Out of available 452 MU URS power, around 320 MU had been scheduled by

SRLDC to different beneficiaries in the region. They requested SRLDC to continue

to scheduling URS power in line with IEGC, based on the requisition by

beneficiaries

12.6 MS I/C, SRPC pointed out that allocation / scheduling of power being carried out is

also based on the corridor availability etc. Real time S1-S2 corridor issue etc. could

be foreseen by SRLDC only.

12.7 All the beneficiary states urged SRLDC to continue with the existing methodology

of allocating/ scheduling of URS power.

12.8 SRLDC informed that a common approach would be adopted throughout all

regions while implementing new Scheduling software as per which URS scheduling

would be done.

12.9 Commercial Sub-Committee suggested that new scheduling software should be

developed in line with the existing methodology of URS power scheduling.

13. DIFFERENCE IN BILATERAL SHEDULES FOR THE MONTH OF JUNE 2014

very cumbersome exercise involving LTA, MTOA, huge number of STOA

transactions. Mismatches were increasing due to increased curtailments, revisions

in trans-regional ISGS etc. In such a complex situation, errors could be minimized

if all stakeholders check the web based schedules on real time basis and furnish

timely feedback on the observed errors.

14.5 SRLDC informed that drawal of AP for for the week 02-06-14 to 08-06-14 had

been verified and the account was found to be in order. Error in Original

Deviation Account R-0 had been corrected by shifting the credit for injection by

AP on 400 kV Khammam Kalpakka D/C line from Telangana drawl to AP’s

drawls. However, as there were number of other changes related to 220 kV lines

and 132 kV lines with regard to polarity corrections, CT/PT ratios etc, due to

which the drawl marginally increased and hence AP remained on the payable


side. Analysis of various components of drawal furnished by SRLDC is given in

following table:
