Current through Register Vol. 48, No. 38, September 20, 2024
a) Beginning in the year 1999 and at least every three years thereafter, the Commission shall assess the annual report of each jurisdictional entity and evaluate its reliability performance. Within thirty days after receiving the Commission's final report on such assessment, the jurisdictional entity may prepare a response to such report. Both the Commission's final report and the jurisdictional entity's response shall be filed with the Chief Clerk of the Commission.
1)
The Commission recognizes that circumstances and events beyond a jurisdictional

evaluating a jurisdictional entity's reliability performance.
2) The Commission evaluation shall:
A) Assess the jurisdictional entity's historical
performance relative to established reliability targets.
B) Identify trends in the jurisdictional entity's
reliability performance.
C) Evaluate the
jurisdictional entity's plan to maintain or improve reliability.
D) Include specific identification, assessment,
and recommendations pertaining to any potential reliability problems and risks that
the Commission has identified as a result of its evaluation.
E) Include a review of the jurisdictional entity's
implementation of its plan for the previous reporting period.
b) Annual report assessment and reliability performance evaluation criteria.
1)
When assessing a jurisdictional entity's annual report, the Commission shall
consider the information listed below.
A)
Information that this Part requires a jurisdictional entity to include in annual
reports.
B) The relevant characteristics
of the area served, including but not limited to system configuration, population
density, and geographical constraints.
C) The age and condition of the system's equipment
and facilities.
D) Generally accepted
engineering practices.
E) The costs of
potential actions.
F) The benefits of
avoiding the risks of service disruptions.
G) The reliability effects of severe weather
events and other events and circumstances that may be beyond the jurisdictional
entity's control.
2) Criteria
for Commission assessment of a jurisdictional entity's annual report.
A) The report must comply with the requirements of
this Part.
B) The report must contain a
plan, as required by Section
411.120(b)(3)(A).
3) When assessing a jurisdictional
entity's reliability performance, the Commission shall consider the information
listed below.
A) Controllable
interruptions.
B) Statistical measures
of interruptions.
C) The number of
interruptions experienced by individual customers.
D) The cumulative hours of interruption
experienced by individual customers.
E)
The jurisdictional entity's actions to prevent interruptions.
F) The jurisdictional entity's responses to
interruptions and to the customers affected by interruptions.
G) The extent to which the jurisdictional entity
has restored interruptions of service to customers on a non-discriminatory basis
without regard to whether a customer has chosen the jurisdictional entity or another
provider of electric power and energy.
H) The number and substance of informal inquiries,
requests for assistance, and complaints directed by customers to the jurisdictional
entity and to the Commission.
I) The
results of customer satisfaction surveys that include customer perceptions of
service reliability.
J) Generally
accepted engineering practices.
K) The
costs of potential actions.
L) The
benefits of avoiding the risks of service disruptions.
M) The reliability effects of severe weather
events and other events and circumstances that may be beyond the jurisdictional
entity's control.
N) Previous Commission
reports and the jurisdictional entity's responses to those reports.
O) Information that this Part requires a
jurisdictional entity to include in annual reports.
P) The relevant characteristics of the area
served, including but not limited to system configuration, population density, and
geographical constraints.
Q) The age and
condition of the system's equipment and facilities.
4) The jurisdictional entity shall strive to
provide electric service to its customers that complies with the targets listed
below.
A) Customers whose immediate primary source
of service operates at 69,000 volts or above should not have experienced:
i) More than three controllable interruptions in
each of the last three consecutive years.
ii) More than nine hours of total interruption
duration due to controllable interruptions in each of the last three consecutive
years.
B) Customers whose
immediate primary source of service operates at more than 15,000 volts, but less
than 69,000 volts, should not have experienced:
i)
More than four controllable interruptions in each of the last three consecutive
years.
ii) More than twelve hours of
total interruption duration due to controllable interruptions in each of the last
three consecutive years.
C)
Customers whose immediate primary source of service operates at 15,000 volts or
below should not have experienced:
i) More than
six controllable interruptions in each of the last three consecutive
years.
ii) More than eighteen hours of
total interruption duration due to controllable interruptions in each of the last
three consecutive years.
D)
Exceeding the service reliability targets is not, in and of itself, an indication of
unreliable service, nor does it constitute a violation of the Act or any Commission
order, rule, direction, or requirement. The Commission's assessment shall determine
if the jurisdictional entity has a process in place to identify, analyze, and
correct service reliability for customers who experience a number or duration of
interruptions that exceeds the targets.
