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).

1 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 operation.

i TEST STATUS is defined as that period following int-tial criticality during which the unit is tested at succes-sisely higher outputs. culminating with operation at full power for a sustamed period and completion of war-ranty runs. Following this phase. the unit is generally considered by the utility to be availab!c for commercial operation.

Date of C0\lilERCIAL OPERATION is defined as the date that the umt was declared by the utility owner to be available for the regular production of electricity.

[ usually related to the satisfactory completion of quali-fication tests as specified in the purchase contract and to the accounting pohcies and practices of the utility.
