19. UNIT SERVICE FACTOR. Compute by dividing hours the generator was on line (item 14) by the gross hours in the reporting period (item i1). Express as percent to the neatest tenth of a percent. Do not include reserve shut-down hours in the calculation.

20. UNIT AVAILABILITY FACTOR. Compute by dividing the unit available hours (item 14 plus item 15) by the gross hours in the reporting period (item 1!). Express as percent to the nearest tenth of a percent.

21. UNIT CAPACITY FACTOR (USING MDC NET). Com-pute by dividing net electrical energy generated (item 18) by the product of maximum dependable capacity (item

7) times the gross hours in the reporting period (item 11).

Express as percent to the nearest tenth of a percent.

22. UNIT CAPACITY FACTOR (USING DER NET). Com-pute as in item 21, substituting design electrical rating (item 5) for maximum dependable capacity.

23. UNIT FORCED OUTAGE RATE. Compute by dividing the total forced outage hours (from the table in Unit Shutdowns and Power Reductions) by the sum of hours generator on line (item 14) plus total forced outage hours (from the table in Unit Shutdowns and Power Reductions).

Express as percent to the nearest tenth of a percent.

24. SilUTDOWNS SCilEDULED OVER NEXT 6 MONTilS (TYPE, DATE. AND DURATION OF EACil). Include type (refaeling, maintenance, other), proposed date of start of shutdown, and proposed length of shutdown.

It is recognized that shutdowns may be scheduled between reports and that this item may not be allinclusive. Be as accurate as possible as of the date the report is prepared.

This item is to be prepared each month and updated if appropriate until the actual shutdown occurs.

25. Self-explanatory.

26. Self-explanatory. Note, however, that this information is requested for all units in startup and power ascension test status and is not required for units already in com-mercial operatton.

TEST STATUS is defined as that period following ini-tial criticahty during which the unit is tested at succes-sively higher outputs. culminating with operation at full power for a sustained period and completion of war-ranty runs. Following tlus phase the umt is generally considered by the utihty to be availab!e for commercial operation.

Date of COMMI'RCIAL OPERATION is detined as the date that the unit was declared by the utility owner to be asailable for the regular production of electrietty.

usually related to the satisfactory completion of quali-tication tests as specified m the purchase contract and to the accoummg policies and practices of the utility.
