Okla. Admin. Code § 165:35-25-20

Current through Vol. 42, No. 7, December 16, 2024

Section 165:35-25-20 - Annual reliability report

(a) Each utility shall submit an annual reliability report to PUD by March 1 of each year, beginning March 1, 2005.

(b) The annual reliability report shall include the following:

(1) A description of all vegetation management it performed for the previous calendar year and the vegetation management it plans to perform for the current year.

(2) SAIDI and SAIFI (and to the maximum extent practicable, MAIFI) values computed for the entire service territory and displayed in tabular form. SAIDI and SAIFI events should be calculated using a sustained time of five (5) minutes or more for Root Mean Square (RMS) zero voltages; MAIFI events should be calculated using any time less than five (5) minutes for RMS zero voltages. Multiple interruptions within five (5) minutes are considered one momentary interruption event.

(3) SAIDI and SAIFI (and to the maximum extent practicable, MAIFI) values computed for each of the utility's regions and displayed in tabular form. SAIDI and SAIFI events should be calculated using a sustained time of five (5) minutes or more for RMS zero voltages; MAIFI events should be calculated using any time less than five (5) minutes for RMS zero voltages. Multiple interruptions within five (5) minutes are considered one momentary interruption event.

(4) A detailed report for each major event that is not included in the calculation of the reliability indices. The major event report shall include the interruption cause or causes, date, regional location, percentages of consumers without service in that region as a result of the event, the time or time frame in which service was lost to 10% or more of that region, the time the last consumer's service was restored in that region, and any other details that the utility or PUD believes will further justify the exclusion of the event from the calculations.

(5) A description of the program the utility has in place for analyzing and improving worst performing circuits and a summary of the results of the program for the reporting year.

(6) A description and map identifying the utility's service regions or operations divisions. Documentation and illustration of any changes in region boundaries as defined by the utility, and justification for such changes.

(7) For each utility with less than 100,000 consumers, show the data used to calculate as well as the calculation of the rural adjusted minimum performance level.

(c) PUD reserves the right to request additional data and/or documents if necessary.

(d)Limitations to technology. Utilities that do not have the technological capability to maintain and compile all such data, shall maintain and compile such data that it has available and utilizes to define and identify system reliability levels as well as outline progress towards attainment of additional technologies.
