Electric Service Reliability
Five-Year Notice of Review and Statement of Continuation
DAR File No.: 41514
Filed: 04/27/2017 07:34:37 AM
NOTICE OF REVIEW AND STATEMENT OF CONTINUATION
Concise explanation of the particular statutory provisions under which the rule is enacted and how these provisions authorize or require the rule:
Section 54-3-1 requires the Public Service Commission (Commission) to establish requirements for each electric corporation and distribution electrical cooperative that is also a public utility to have a program to ensure reliable electric service is provided to each electric service customer.
Summary of written comments received during and since the last five-year review of the rule from interested persons supporting or opposing the rule:
This rule was proposed by the Commission on 04/15/2012. On 08/01/2012, a change of proposed rule was filed. Changes were based upon the consideration of comments received on the initial version of the rule and the desire to incorporate the 05/21/2012 version of Standard IEEE 1366-2012 Guide for Electric Power Distribution Reliability Indices (which was published after the initial 05/15/2012 filing deadline for the proposed rule) as the foundation for the rule. The changes provided more flexibility for an electric corporation to develop, manage, and revise its electric service reliability program while requiring the electric corporation to meet Commission-approved levels of reliability. When the rule was amended on 12/20/2012, Rocky Mountain Power recommended to replace the requirement for an electric corporation to report Momentary Average Interruption Frequency Index (MAIFI) data with the requirement to report Momentary Average Interruption Frequency Index Event (MAIFIe) data, to clarify reporting requirements for MAIFIe data and to make other minor changes. As proposed by Rocky Mountain Power, the impact of momentary electric service interruption experienced by a customer is related to the entire momentary event (as represented by MAIFIe) rather than the electric system's attempts to automatically restore power after a fault event (as represented by MAIFI). Therefore, the electric service reliability rules addressing momentary outages should reference MAIFIe not MAIFI.
Reasoned justification for continuation of the rule, including reasons why the agency disagrees with comments in opposition to the rule, if any:
The rule should remain in effect to allow the Public Service Commission to require utilities to have a program to ensure reliable electric service is provided to each electric service customer. Therefore, this rule should be continued.
