83 Ill. Adm. Code 501.520
Interruptions of Service
Section 501.520 Interruptions of Service
a) Each
utility shall make all reasonable efforts to prevent interruptions of service.
When interruptions occur, the utility shall reestablish service with the
shortest possible delay, consistent with general safety and public welfare.
Whenever a utility must interrupt its customers' service for the purpose of
working on the system, the utility shall conduct this work at a time that will
cause the least inconvenience to customers, and the utility shall notify, in
advance and in writing, the customers who will be affected by the interruption.
Advanced notification is not required whenever a utility interrupts service for
emergency work on a matter that represents an existing or probable hazard to
persons or property, and requires immediate repair or continuous action until
the conditions are no longer hazardous. A utility shall notify the Director of
the Safety and Reliability Division and the Director of the Consumer Services
Division by phone during working hours or via fax or email during non-working
hours if it has interrupted service to more than 50 customers for a period of
12 hours or more.
b) Each
utility shall annually file a report with the Director of the Safety and
Reliability Division by April 1 that details the prior calendar year's service
interruptions that affected more than 25 customers for longer than eight hours.
The utility shall include the following information in the report:
1) Indicate
the number of service interruptions that:
A) Lasted
8 or more hours, but less than 12 hours.
B) Lasted
12 or more hours.
2) Dates
of service interruption that exceeded 8 hours in length.
3) City and
location of service interruptions that exceeded 8 hours in length.
4) Reason
for service interruptions that exceeded 8 hours in length.
c) The
provisions of this Section shall not apply to customers receiving gas service
on an interruptible basis.
d) A
utility shall measure a service interruption beginning at the time the utility
becomes aware of the interruption and ending when the utility reestablishes
service or makes a first attempt at visiting a customer's premises for the
purpose of reestablishing service.
