A.

the utility's SAIDI for the calendar year, by work center and for its assigned service area as a whole;

B.

the utility's SAIFI for the calendar year, by work center and for its assigned service area as a whole;

C.

the utility's CAIDI for the calendar year, by work center and for its assigned service area as a whole;

D.

an explanation of how the utility normalizes its reliability data to account for major storms;

E.

an action plan for remedying any failure to comply with the reliability standards set forth in part 7826.0600 or an explanation as to why noncompliance was unavoidable under the circumstances;

F.

to the extent feasible, a report on each interruption of a bulk power supply facility during the calendar year, including the reasons for interruption, duration of interruption, and any remedial steps that have been taken or will be taken to prevent future interruption;

G.

a copy of each report filed under part 7826.0700;

H.

to the extent technically feasible, circuit interruption data, including identifying the worst performing circuit in each work center, stating the criteria the utility used to identify the worst performing circuit, stating the circuit's SAIDI, SAIFI, and CAIDI, explaining the reasons that the circuit's performance is in last place, and describing any operational changes the utility has made, is considering, or intends to make to improve its performance;

I.

data on all known instances in which nominal electric service voltages on the utility's side of the meter did not meet the standards of the American National Standards Institute for nominal system voltages greater or less than voltage range B;

J.

data on staffing levels at each work center, including the number of full-time equivalent positions held by field employees responsible for responding to trouble and for the operation and maintenance of distribution lines; and

K.

any other information the utility considers relevant in evaluating its reliability performance over the calendar year.

Subp. 2.

Initial reporting requirements.

By March 30, 2003, each utility shall file its SAIDI, SAIFI, and CAIDI for each of the past five calendar years, by work center and for its assigned service area as a whole. If this information is not available, the utility shall file an explanation of how it has been tracking reliability for the past five years, together with reliability data for that period of time. If the utility has implemented a new reliability tracking system that makes comparisons between historical data and current data unreliable, the utility shall explain this situation in its filing.
