The input of operation hours of the two options "With Modernization“ and "Without Modernization“ is detailed per month. Here shown for the first option "With Modernization".
 

In the data input sheet "Power_M“, the monthly operating hours before the modernization and after the modernization are considered.

 
The "Old plant“ operates until March 2003 (line "2003-03“) with 583 hrs/month, equivalent to 7000 hrs/yr, and then stops.

 

 
 
After a gap of three months downtime, the "New plant“ starts its operation again in July 2003 with 633 hrs/month, equivalent to 7600 hrs/yr.
