Current through all regulations passed and filed through August 26, 2022
(A) General. This rule sets forth a method
for determining the performance of each electric utility's distribution
(B) Circuit performance
methodology. The following provisions apply to the determination of the
appropriate method for calculating circuit performance.
(1) Circuit performance data during major
events and transmission outages shall be excluded from the calculation of
electric utility shall submit, for review and acceptance by the director of the
service monitoring and enforcement department, a method to calculate circuit
performance, based on the service reliability indices defined in paragraph
(B)(1) of rule
of the Administrative Code and other factors proposed by the electric utility,
and supporting justification for that method. An electric utility may revise
the method it uses for calculating circuit performance (starting with the next
succeeding reporting period) by submitting such revisions and supporting
justification for such revisions to the director of the service monitoring and
enforcement department for review and acceptance.
(3) If the electric utility and the director
of the service monitoring and enforcement department cannot agree on the method
to calculate circuit performance, then the director of the service monitoring
and enforcement department shall issue a letter rejecting the proposal within
forty-five calendar days of its submittal. The electric utility or the director
may request a hearing to establish the appropriate calculation methodology. At
such hearing, the burden of proof to show that the calculation methodology is
just and reasonable shall be upon the electric utility.
(4) No proposal shall be effective until it
is either accepted by the director or, in the event of a hearing, approved by
performing circuits. The following provisions apply to the reporting of each
electric utility's eight per cent worst performing circuits:
(1) Each electric utility shall submit, no
later than ninety calendar days after the end of its reporting period, a report
to the director of the service monitoring and enforcement department that
identifies the worst performing eight per cent of the electric utility's
distribution circuits during the previous twelve-month reporting
(2) Unless otherwise
approved by the commission, each electric utility's reporting period for
purposes of paragraph (C) of this rule shall begin on September first of each
year and shall end on August thirty-first of the subsequent year.
(3) The report prescribed by paragraph (C) of
this rule shall provide the following information for each reported
(a) The circuit
location of the primary area served by the circuit.
(c) The approximate number of customers on
the circuit by customer class.
The circuit ranking value.
values and supporting data for each circuit's service reliability indices for
the reporting period:
(i) System average
interruption frequency index (SAIFI) determined according to paragraph (B)(1)
of the Administrative Code.
Customer average interruption duration index (CAIDI) determined according to
paragraph (B)(1) of rule
of the Administrative Code.
System average interruption duration index calculated by multiplying the SAIFI
times the CAIDI.
number of safety and reliability complaints, based on the definition of
complaint pursuant to paragraph (A) of rule
of the Administrative Code.
number of critical customers on the circuit.
(h) An identification of each circuit lockout
that occurred during the reporting period, together with an explanation of the
cause and duration of each such circuit lockout.
(i) The total number of outages
experienced during the reporting period for each such outage.
The total number of out-of-service minutes experienced during the reporting
period for each such outage.
(i) An identification
of any major factors or events that specifically caused the circuit to be
reported among the worst performing circuits and, if applicable, the analysis
performed to determine those major factors.
(j) An action plan,
including the start and completion dates of all remedial action taken or
planned, to improve circuit performance to a level that removes the circuit
from the report submitted pursuant to paragraph (C) of this rule within the
next two reporting periods. If the electric utility does not believe remedial
action is necessary, then the electric utility must state the rationale for not
taking any remedial action.
(D) If the director of the service monitoring
and enforcement department believes that an action plan submitted pursuant to
paragraph (C)(3)(l) of this rule is insufficient or unreasonable, the director
shall provide written notice to the electric utility within forty-five calendar
days of the submittal, otherwise the report is deemed approved. Should no
agreement be reached between the electric utility and the director of the
service monitoring and enforcement department on a modified action plan, within
thirty calendar days following the rejection of the action plan, the electric
utility shall apply to the commission for a hearing. At such hearing, the
burden of proof to show that the modified action plan is just and reasonable
shall be upon the electric utility.
(E) Each electric utility shall submit the
reports required by this rule, on electronic media, in a format prescribed by
the commission or its staff.
Electric utilities shall take sufficient remedial action to make sure that no
circuit is listed on three consecutive reports. The inclusion of a given
circuit in the report under paragraph (C) of this rule for three consecutive
reporting periods shall create a rebuttable presumption of a violation of this
