Annual performance

1. INTRODUCTION
As per rule 25 of the Rules of Business each Ministry/Division on the beginning of each
financial year has to prepare and upload on its website as a permanent record a year book; The
Annual Performance Reports should include at least the following information:-
(a) System Performance Reports
(b) Consumer Service Performance Reports
(c) Analysis of performance parameters through descriptive & graphical representation based on
the data reported by the company. The analysis is based on the following parameters:-
• Transmission & Distribution Losses,
• Recovery in percentage,
• System Average Interruption Frequency Index (SAIFI),
• System Average Interruption Duration Index (SAIDI),
• Percentage consumers who were not given new connection in permitted time period,
• Total number of consumers who made complaints about Voltage,
• Average duration of load shedding (hrs.),
• Total Consumer Service Complaints received by DISCO during the year,
• Fault Rate (faults/km) of distribution system,
• Electrical incident resulting in death or permanent serious injury/disability to the member
of staff or public.
Performance against standard distribution rules, 2005 defined by NEPRA are stated as under
