OAR 860-023-0151
Annual Report on Electric Reliability


(1)

On or before May 1 of each year, an electric company must file with the Commission a report that includes the information set forth in section (2) of this rule for the reporting period. The electric company must file the report in electronic form. The electric company must make electronic copies of the report available to the public upon request. For paper copies requested by the public, the electric company may charge a reasonable cost for production of the copy.

(2)

The annual Electric Service Reliability Report must contain:

(a)

The results of the calculated SAIDI, SAIFI, and MAIFIE indices required by OAR 860-023-0111 (Electric Reliability Calculations). The electric company must also report this information on a system-wide basis compared with the previous four years’ performance, and on a reliability reporting area basis compared with the previous four years’ performance.

(b)

A summary of system-wide and reliability reporting area sustained interruption causes compared to the previous four-year performance. Cause categories to be evaluated include:

(A)

Loss of Supply — Transmission;

(B)

Loss of Supply — Substation;

(C)

Distribution — Equipment;

(D)

Distribution — Lightning;

(E)

Distribution — Planned;

(F)

Distribution — Public;

(G)

Distribution — Vegetation;

(H)

Distribution — Weather (other than lightning);

(I)

Distribution — Wildlife;

(J)

Distribution — Unknown; and

(K)

Distribution — Other.

(c)

A listing of the Major Events experienced during the reporting period, including reliability reporting area involved; operating areas involved; dates involved; TMED applied; interruption causes; and SAIDI, SAIFI, and CAIDI impacts to customers for the Event on both a reliability reporting area basis and a system-wide basis.

(d)

A listing of the TMED values that will be used for each reliability reporting area for the forthcoming annual reporting period compared with the previous four years of TMED values.

(e)

A summary of the characteristics of the systems covered under OAR 860-023-0091 (Electric Service Continuity)(4) and estimation methodologies covered by OAR 860-023-0101 (Electric Interruption Records)(3) and 860-023-0111 (Electric Reliability Calculations)(3) for the collection of interruption data, calculation of reliability information, and facilitation of interruption restoration and mitigation.

(f)

A summary addressing the changes that the electric company has made or will make in the collection of data and the calculation, estimation, and reporting of reliability information. The electric company must explain why the changes occurred and explain how the change affects the comparison of newer and older information.

(g)

A map showing the reliability reporting areas and operating- areas.

(h)

A listing of circuits by reliability reporting area and substation, indicating circuit voltage and number of customers connected.

(3)

This rule is effective beginning January 1, 2012.
