LICENSEES’ STANDARDS OF
PERFORMANCE
Introduction :
In order to improve reliability
and quality of supply, the Commission notified “Standards of Performance” to be

to High Tension and payment of necessary charges by
vice-versa the consumer
Provided that in case of conversion from Low Tension to High Tension and vice-versa, the Licensee shall not be held responsible for the delay if the same is on account of delay in consumer’s obligation to obtain approval of Chief Electrical Inspector to Government, for such installation.

SCHEDULE-III
Overall Standards
of Performance
1.1 Normal fuse-off calls: The
Licensee shall maintain the percentage of fuse-off calls rectified within the
time limits prescribed under sub-paragraph 1.1 of Schedule-I to total calls
received at a value not less than 99%.
1.2 Line Breakdowns: In case of line breakdowns, the Licensee shall ensure restoration of power supply within 6 hours of occurrence of breakdown in towns and cities and within 24 hours of occurrence of breakdown in rural areas as prescribed in sub-paragraph 1.2 of Schedule-I. The Licensee shall achieve this standard of performance in at least 95% of the cases.
1.3 Distribution Transformer Failures: The Licensee shall maintain the percentage of distribution transformers replaced within the time limits prescribed in sub-paragraph 1.3 of Schedule-I to the total distribution transformers failed at a value not less than 95%.
1.4 Period of scheduled outages: As
specified in sub-paragraph 1.5 of Schedule-I, interruption in power supply due
to scheduled outages, other than the load-shedding, has
to be notified in advance and shall not exceed 12 hours in a day and in each
such event, the Licensee has to ensure that the supply is restored by
1.5 Street Light faults
1.5.1 The Licensee shall rectify line faults and restore streetlights within 24 hours of detection or receipt of complaint, whichever is earlier, and shall achieve this standard of performance in at least 90% of the cases.
1.5.2 In case of a fused light or defective unit, the Licensee, wherever responsible for maintenance of street lights, shall replace the light or rectify/replace the unit within 24 hours of detection or receipt of complaint, whichever is earlier, and shall achieve this standards of performance in at least 90% of the cases.
1.6 Reliability Indices
(i)
The following reliability/outage indices are prescribed
by the
(a) System Average Interruption Frequency Index
(SAIFI): The Licensee shall calculate the value as per the
formula and methodology specified below.
(b)
System
Average Interruption Duration Index (SAIDI): The Licensee shall calculate
the value as per the formula and methodology specified below.
(c)
Momentary
Average Interruption Frequency Index (MAIFI):
The Licensee shall calculate the value as per the formula and methodology
specified below.
Method to compute Distribution System Reliability Indices
The Indices shall be computed for the Discom as a whole by stacking, for each month all the 11KV/33KV feeders in the supply area, excluding those serving predominantly agricultural loads, and then aggregating the number and duration of all interruptions in that month for each feeder. The Indices would then be computed using the following formulae:
1. SAIFI =
Where,
2. SAIDI =
Where,
3. MAIFI =
Where,
Note: The feeders must be
segregated into rural and urban and the value of the indices must be reported
separately for each month.
(i) The
Licensee shall compute the value of these indices separately for feeders
serving predominantly agricultural loads. The methodology for computation of
indices shall remain the same as in the case of other feeders.
(ii)
Based
on the information provided by the Licensees, the Commission would notify the
target levels for these indices annually.
1.7 Frequency variations: The
Licensee shall achieve coordination with other network constituents such as
State Transmission Utility, State Load Dispatch Center, distribution Licensees
and other transmission Licensees in an endeavour to maintain the supply
frequency as per the Indian Electricity
Grid Code (the present values being between 49.0 and 50.5 Hz), as amended from
time to time. The Licensee shall conduct hourly measurement of supply frequency
and report the number of events when the supply frequency was outside
prescribed limits.
1.8 Voltage Unbalance: The Licensee shall ensure that the voltage unbalance does not exceed 3% at the point of commencement of supply. Voltage Unbalance shall be computed in a manner to be specified by the Commission separately or as part of the Distribution Code or Distribution Operating Standards.
1.9 Billing mistakes: The Licensee shall maintain the percentage of bills requiring modifications following complaints to the total number of bills issued, at a value not greater than 0.1%.
1.10 Faulty meters: The Licensee shall maintain the percentage of defective meters to the total number of meters in service, at a value not greater than 3%.
