mercial operation.

TEST STATUS is defined as that period following ini-tial criticality during which the unit is tested at succes-sively higher outputs. et.iminating with operation at full power for a sustained period and completion of war-ranty runs. Following this phase, the unit is generally considered by the utility to be available for com nercial operation.

Date of COMMERCIAL OPERATION is defined as the date that the unit was declared by the utility owner to be available for the regular prodnetion of electricity.
