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

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

7) times the grcss hours in the reporting penod (item i1).

Express as percent to the nearest tenth of a percent.

20. 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 octage hours (from the table in Unit Shutdowns and Power Reductions).

Express as percent to the nearest tenth of a percent.

24. SHLTDOWNS SCHEDULED OVER NEXT 6 MONTHS (TYPE. DATE. AND DURATION OF EACH). Include typ (refueling. maintenance, other), proposed date of start of shutdown and proposed length of shutdown.

It :s recognized that shutdowns may be schedu!ed between repotts 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 appropnate until the actual shutdown occurs.

25. Self<xplanatory.

!6. Self. explanatory. Note, however, that this information is requested for all units m startup and power ascension test status and is not required for umts already in com-mercial operation.

TEST STATUS is defined as that pened following mi-tial enticality dunng which the unit is tested at succes-sively higher outputs, eu!mmatmg with operation at full power for a sustamed pened and completion of war-ranty suns. Fol!owmg this phase, the umt is generally considered by the utility to be available for commercial operation.

Date ot' COMMERCIAL OPERATION is defined as the date that the unit was declared by the utility owner to be available for the regular production of electneity, usually reisted to.the satisfactory completion of quali.

rication tests as specified in the purchase contract and to the accountmg policies and practices of the utility.
