I am new guy as an electrical engr. in a 100MW HFO based power project. I am in operations division. I have noticed from last few days, my supervisor sends the last 24 hours energy generation calculation to my plant manager. I have noticed, he calculated last 24 hour's generated energy differences in KWH then he multiplied it with a multiplying factor 960. for example: total difference =2.685 KWH*960= 2577.6 MWH. but he does not not know what is multiplying factor 960?? can anybody explain it??
