(B) Service reliability indices and minimum
performance standards.
(1) The service
reliability indices are as follows:
"CAIDI," or the customer average interruption duration index,
represents the average interruption duration or average time to restore service
per interrupted customer. CAIDI is expressed by the following formula:
CAIDI equals sum of customer interruption durations divided by
total number of customer interruptions
"SAIFI," or the system average interruption frequency index,
represents the average number of interruptions per customer. SAIFI is expressed
by the following formula:
SAIFI equals total number of customer interruptions divided by
total number of customers served
(2) Each electric utility in this state shall
file with the commission an application to establish company-specific minimum
reliability performance standards.
(3) Applications for approval of a
reliability performance standard shall include:
(a) A proposed methodology for establishing
reliability standards.
(b) A
proposed company-specific reliability performance standard for each service
reliability index based on the proposed methodology.
(c) Supporting justification for the proposed
methodology and each resulting performance standard.
(4) Supporting justification for the proposed
methodology and each resulting performance standard.
(a) Performance standards should reflect
historical system performance, system design, technological advancements,
service area geography, customer perception survey results as defined in
paragraph (B)(4)(b) of this rule, and other relevant factors.
(b) Each electric utility shall periodically
(no less than every three years) conduct a customer perception survey. The
survey results shall also be used as an input to the methodology for
calculating new performance standards. The survey shall be paid for by the
electric utility and shall be conducted under staff oversight. The objective of
the survey is to measure customer perceptions, including, but not limited to
expectations of electric service reliability in terms of the service
reliability indices defined in paragraph (B)(1) of this rule.
(c) Performance data during major events and
transmission outages shall be excluded from the calculation of the indices,
proposed standards, and any revised performance standards, as set forth in
paragraph (B) of this rule.
(5) A complete set of work papers
must be filed with the application. Work papers must include, but are not
limited to, any and all documents prepared by the electric utility for the
application, a list of assumptions used in establishing its proposed
methodology, and a narrative or other justification for its proposed
methodology and each resulting performance standard.
(6)(5) Unless otherwise
ordered by the commission, legal director, deputy legal director, or attorney
examiner, the following procedural schedule shall apply:
(a) Upon the filing of an application, the
commission, legal director, deputy legal director, or an attorney examiner will
schedule a technical conference. The purpose of the technical conference is to
allow interested persons an opportunity to better understand the electric
utility's application. The electric utility will have the necessary personnel
in attendance at this conference so as to explain, among other things, the
filing, the work papers and the manner in which methodologies and resulting
performance standards were devised. The conference will be held at the
commission offices.
(b) Within
twenty calendar days after the technical conference, any person may file
comments.
(c) Within thirty
calendar days after the technical conference, the commission's staff may file
comments.
(d) Within fifty calendar
days after the technical conference, any person may file a response to the
comments.
(e) If it appears to the commission
that the proposals in the application may be unjust or unreasonable, the
commission shall set the matter for hearing and shall publish notice of the
hearing in accordance with section 4909.10 of the Revised Code. At such
hearing, the burden of proof to show that the proposals in the application are
just and reasonable shall be upon the electric utility.
(f)(e)
If the commission schedules a hearing,Interested
interested
persons wishing to participate in the hearing shall
may file a
motion to intervene no later than thirty calendar days after the issuance of
the entry scheduling the hearing, unless ordered otherwise by the commission,
legal director, deputy legal director, or attorney examiner. This rule does not
prohibit the filing of a motion to intervene and conducting discovery prior to
the issuance of an entry scheduling a hearing.
(7)(6) An
electric utility may request to revise its authorized performance standards by
filing its revisions and supporting justification for such revisions with the
commission for approval pursuant to paragraph (B)(6) of this rule, unless
otherwise ordered by the commission, legal director, deputy legal director, or
attorney examiner.
(8)(7) The authorized
performance standards approved for an electric utility shall remain in place
until superseded by revised standards as approved by the commission.
(C) Annual report. Each electric
utility shall file with the commission an annual report by March thirty-first
of each year. That annual report shall include the following information
regarding the previous calendar year:
(1)
Annual performance and supporting data for each service reliability index set
forth in paragraph (B) of this rule both with and without exclusions for major
events and transmission outages. Supporting data includes, for example, the
number of customers served, the number of customer interruptions, the number of
customer minutes interrupted, SAIFI data for a major event, CAIDI data for a
major event, information concerning a transmission interruption, and a listing
of distribution circuits interrupted during a transmission
interruption.
(2) Performance on
the same indices during major events and transmission outages, reported in
separate categories with their respective supporting data.
(3) Data for the total number of sustained
outages, customers interrupted, and customer minutes interrupted for each
outage cause code, all of which shall be reported in the following versions:
(a) Data excluding major events and
transmission outages.
(b) Data for
major events only.
(c) Data for
transmission outages only.
(4) Data for the total number of
momentary interruptions on the electric utility's system where
practicable.
(5)(4) Each electric
utility shall file the annual report required by paragraph (C) of this rule in
an electronic form prescribed by the commission or its staff.
(D) If the annual performance of
an electric utility does not meet the electric utility's performance standard
for any index, the electric utility shall file with the commission an action
plan, by March thirty-first of the year following the year when the standard
was missed.
The action plan shall include the following:
(1) Factors which contributed to the actual
performance level for that index.
(2) A proposal for improving performance to a
level that meets or exceeds the performance standards authorized for each
missed reliability index, including each action taken or planned to be taken,
and the anticipated completion date.
(2) The action plan shall be filed
in an electronic form prescribed by the commission or its
staff.
(3) A status report on each action
included in the action plan shall be submitted to the director of the service
monitoring and enforcement department upon request of the
staff.
