RE: WEPCO Capacity Demonstration (Port Washington Power Plant) 

FROM: Walt Stevenson <_£ 

This note and attached data summarize the recent Port Washington 

Power Plant capacity tests. Two of the units achieved full 

Maximum Continuous Rating (MCR), the others did not. As shown by 

the attachments, units 2 and 3 achieved full design MCR and unit? 

1 and 4 demonstrated 287. and 117. derate, respectively. WEPCO did 

not operate unit 5 and it is assumed that unit 5 cannot be 

operated (100% derate)

(a; Demonstrated NCR is lowest 1-hr operating level during 50 hr test. 

it! The percent derate for anit-1 and unit-? is equal to SG2 reduction requirement. 

For unit-5. Subpart Da 70-90 2 reduction requirement would apply. 

!c) The 1-hr peak load exceeded the NCR !50 hr value) by this asiount. 

For short periods, a new power plant can exceed its design MCR level by 3 to 57..
