- The limits of permissible variations in voltages at various levels have to be fixed on the basis of existing network, spare capacity, etc., and always be improved with system improvements, capacity generation and various other related factors. Hence, even though the ideal situations would be different, the bandwidth of variations has to reflect the actual condition and has to be specified after periodical reviews. Accordingly, the Commission, from time to time, will order the permissible limits for voltage variations.The frequency variations shall be governed by the National / State Grid Code and hence not specified under this regulation

15. Voltage complaints.

'25. Service reliability:- Reliability of the distribution system operated by the distribution licensee shall be computed on the basis of number and duration of interruptions in a year. Reliability standards shall be judged by two indices, namely, consumer's average interruption frequency index (CAIFI), consumer’s average interruption duration index (CAIDI).Each distribution licensee shall formulate a suitable model on the basis of his geographical spread of the network to reveal the real ity of the situation on the above two indices and set standards of performance. The model shall begot approved by the Commission and can be distinct for each licensee.]]- 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:
(a)System Average Interruption Frequency Index (SAJFI)
(b)System Average Interruption Duration Index (SAIDI)
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 11KV/22KV 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:n∑ (A1*n1)
| 1. Saifi =| i-1N1
Where,Ai = Total number of sustained interruptions (each longer than 5 minutes) on with feeder for the monthNi = Connected load of with feeder affected due to each interruptionNt = Total connected load at 11/22 KV in the Distribution licensee's supply arean = number of 11/22 KV feeders in the licensed area of supply (excluding those serving predominantly agricultural loads)n∑ (B1*n1)
| 2. Saidi =| i-1N1
Where,Bi = Total duration of all sustained interruptions on this 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.
(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.]

26. Regulation to be read with Supply Code, Distribution Code, etc.

(1)As these regulations are intended to enforce quality, continuity and reliability of service, these regulations shall be read along with Supply Code, Distribution Code, Grid Code and other relevant provisions of the Act, rules and regulations made thereunder pertaining to supply and consumption of electricity.
(2)Where any of the provisions in these regulations is found to be inconsistent with those of the Act, rules or regulations made thereunder, notwithstanding such inconsistency, the remaining provisions in these regulations shall remain operative.
