Changes for NPRR595 and NPRR698:

o       New Settlement Calculation Revisions:

1.   Real-Time Capacity from Controllable Load Resources for the Qualified Scheduling Entity (QSE)

RTCLRCAPq = (RTCLRNPC q – RTCLRLPCq – RTCLRNSq  ) + RTCLRREGq

RTCLRREG q = SYS_GEN_DISCFACTOR */cgi-bin/wa?A3=1510&L=NOTICE_PRR_SCR&E=base64&P=51955&B=--_006_A1C95E722D016D4EAE77BC454B4AA41555C4707ECPW0012_&T=image%2Fpng;%20name=%22image001.png%22&N=image001.png RTCLRREGR q,r,p 

2.   Real-Time Capacity from Non-Controllable Load Resources carrying Responsive Reserve (RRS) for the QSE

RTNCLRCAPq = RTNCLRNPC q – RTNCLRLPCq

 

Where:

 

        RTNCLRNPC q = SYS_GEN_DISCFACTOR */cgi-bin/wa?A3=1510&L=NOTICE_PRR_SCR&E=base64&P=51955&B=--_006_A1C95E722D016D4EAE77BC454B4AA41555C4707ECPW0012_&T=image%2Fpng;%20name=%22image001.png%22&N=image001.pngRTNCLRNPCR q,r,p 

 

        RTNCLRLPC q = SYS_GEN_DISCFACTOR */cgi-bin/wa?A3=1510&L=NOTICE_PRR_SCR&E=base64&P=51955&B=--_006_A1C95E722D016D4EAE77BC454B4AA41555C4707ECPW0012_&T=image%2Fpng;%20name=%22image001.png%22&N=image001.pngRTNCLRLPCR q,r,p 

3.    Real-Time On-Line Capacity

 

RTOLCAP q = (RTOLHSL q – RTMGQ q – SYS_GEN_DISCFACTOR * (/cgi-bin/wa?A3=1510&L=NOTICE_PRR_SCR&E=base64&P=52934&B=--_006_A1C95E722D016D4EAE77BC454B4AA41555C4707ECPW0012_&T=image%2Fpng;%20name=%22image002.png%22&N=image002.png/cgi-bin/wa?A3=1510&L=NOTICE_PRR_SCR&E=base64&P=53775&B=--_006_A1C95E722D016D4EAE77BC454B4AA41555C4707ECPW0012_&T=image%2Fpng;%20name=%22image003.png%22&N=image003.pngUGENA q,r,p)) +   RTCLRCAP q + RTNCLRCAP q
