Electric Reliability Calculations
(1)
Using records collected per OAR 860-023-0101 (Electric Interruption Records), each electric company must perform annual reliability index calculations required by this rule in compliance with IEEE 1366. Each electric company must report the results of the calculations in the company’s annual report as set forth in 860-023-0151 (Annual Report on Electric Reliability) and in the company’s major event filings as set forth in 860-023-0161 (Major Event Filing by Electric Companies).(2)
After December 31 of each year an electric company must calculate the SAIDI, SAIFI, and MAIFIE indices for the previous reporting period. These indices are to be calculated both with all interruptions included and separately with major event interruptions excluded:(a)
On a system-wide basis;(b)
For each reliability reporting area; and(c)
For each circuit.(3)
If an electric company estimates or uses factors in calculating actual CAIDI, SAIDI, SAIFI, or MAIFIE indices in sections (1) or (2) of this rule, the company must summarize the estimation methodologies in the company’s annual report, as set forth in OAR 860-023-0151 (Annual Report on Electric Reliability).(4)
This rule is effective beginning January 1, 2012.
