3.3 In case of applications requiring supply under agriculture category (Agriculture Pump sets) licensee’s obligation shall be limited to the number of connections that can be covered within the target fixed by the State Government for release of agricultural connections for a financial year. The target for an ensuing year should be fixed and made public at least 2 months before the commencement of the year. The licensee shall inform the applicants in writing within 15 days of receipt of applications, if the applicants’ case cannot be covered in the programme of release of Agriculture Pump set connections fixed for the year.
3.4
Schedule II relates to Overall
Standards of Performance, which indicates the level of performance the licensee
shall seek to achieve in the discharge of his obligations as a licensee.![]()
The
Commission may, at any time, add, vary, alter, modify or amend any of the

III.![]()
5.1 The standards of performance specified in these regulations shall remain suspended during Force Majeure conditions such as war, mutiny, civil commotion, riot, flood, cyclone, lightning, earthquake or other causes beyond the control of the Licensee and strike, lockout, fire affecting the licensee’s installations and activities.
5.2
The Commission may by a general or special order, issued for the purpose,
after hearing the Licensee and the affected consumer group relieve the Licensee
from the liability to compensate the consumers for any default in the
performance of any standard if the Commission is satisfied that such default is
for reasons other than those attributable to the Licensee & beyond the
control of the Licensee and further that the Licensee has otherwise made efforts
to fulfill his obligations.![]()
6.1 If the Licensee fails to meet the Standards of Performance specified in Schedule I, the licensee shall pay to the affected consumer against whom no arrear is pending on the date of violation, the compensation as indicated against each of the Standards of Performance in Schedule I.
6.2 The Licensee shall register every complaint of a consumer. The Licensee shall computerise the registration of every complaint of a consumer through automatic answering machine or any other such means intimating the complaint number to the consumer automatically.
6.3 The Licensee shall maintain relevant records consumer-wise regarding the Standards of performance in order to give a fair treatment to all consumers and avoid any dispute regarding violation of standards.
6.4 All payment of compensation shall be made by way of adjustment against existing, current and/or future bills for supply of electricity.
Provided the compensation shall be paid in Cash/ Demand draft wherever the claimant ceases to be the consumer of the utility.
Provided
that all the compensation shall be made within 90 days from the date of
violation of a guaranteed standard of performance. If the Compensation is not
adjustable in the existing, current and/or future bills of the supply of
electricity the same should be paid in cash / demand draft to ensure that the
compensation is paid within 90 days from the date of violation of a guaranteed
standard of performance.![]()
7. Procedure for payment of compensation

standard of performance.![]()
CHAPTER IV FURNISHING INFORMATION, ISSUE OF ORDERS
8. Information on Standards of Performance
8.1 Every Licensee shall furnish to the Commission the following information in the Performa placed at Schedule-III.
a The level of performance achieved in respect of matters covered in schedule I and II of these Regulations shall be furnished quarterly.
b The number of cases in which compensation was paid under these Regulations and amount of the compensation in each case, shall be furnished quarterly.
8.2 The Commission shall arrange for publication of the above information, at least once in a year, in the manner as deemed fit.
8.3 Reliability Indices
(a) The following reliability/outage indices are prescribed by the Institute of Electrical and Electronics Engineers (IEEE) Standard 1366 of 1998. The licensee shall compute and report the value of these indices as per the formula and methodology specified below from 2004-05 onwards:
(i) System Average Interruption Frequency Index (SAIFI):
(ii) System Average Interruption Duration Index (SAIDI):
(iii) Momentary Average Interruption Frequency Index (MAIFI):
(b) Method to compute Distribution System Reliability Indices
The Indices shall be computed for the Distribution licensee as a whole by stacking, for each month, all the 11 KV 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 formula:
Where,
Ai = Total number of sustained interruptions (each longer than 5 minutes) on ith feeder for the month
Ni = Connected load of ith feeder affected due to each interruption
Nt = Total connected load at 11KV in the Distribution licensee’s supply area
n = Number of 11KV feeders in the licensed area of supply (excluding those serving predominantly agricultural loads)
Where,
Bi = Total duration of all sustained interruptions on ith feeder for the month.
Where,
Ci = Total number of momentary interruptions (each less than or equal to 5 minutes) on ith feeder for the month
Note: The feeders must be segregated into rural and urban and the value of the indices must be reported separately for each month. However interruptions due to load restrictions, power cut, shut down shall not be taken into account while calculating the indices
(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.![]()
9. Issue of orders and ‘practice’ directions
Subject to the
provisions of the Act and these regulations, the Commission may, from time to
time, issue orders and ‘practice’ directions in regard to the implementation
of the Regulations and Procedures to be followed.![]()
10. Power to remove difficulties
10.1 If any difficulty arises in giving effect to any of the provisions of these regulations, the Commission may, by general or special order, direct the licensee to do anything not being inconsistent with the provisions of the Act, which appears to it to be necessary or expedient for the purpose of removing the difficulties.
10.2 The Licensee may make an application to
the Commission and seek suitable orders to remove any difficulty that may arise
in implementation of these Regulations.![]()
11. Implementation / Transition Period
The
standard indicating the maximum time limit for rendering the service is in line
with the documents already approved by the Commission. Thus the licensee should
not face any difficulty in the implementation of the same. However, the Licensee
would be allowed a period of six months from the date of notification of this
regulation for putting the required infrastructure in place. From 1st
February 2005 the mock exercise would be carried out to make the system
perfect and implementable. The actual payment of monetary compensation to the
consumer w.r.t the provisions of these regulations would start from 1st
August 2005 for urban consumers and from 1st August 2006
for rural consumers.![]()
Nothing in these regulations shall affect the rights and privileges of the consumers under any other law including the Consumer Protection Act, 1986 (Act 68 of 1986).
