(4) The Real-Time Settlement Point Price of the Hub for a given 15-minute Settlement Interval is calculated as follows: RTSPP = Max [-$251, (RTRSVPOR + RTRDP + South345 (HUBDF * ((RTHBP * hb, South345 hb, South345, y TLMP / (TLMP if HB y) y))))], South345≠0 RTSPP = RTSPPERCOT345Bus, if HB South345 South345=0 Where: RTRSVPOR = (RNWF * RTORPA y y) RTRDP = ( RNWFy * RTORDPAy) / RNWF = TLMP TLMP y y y RTHBP = (HBDF * RTLMP hb, South345, y b, hb, South345 b, hb, South345, y) / HUBDF = IF(HB 0, 1 HB hb, South345 South345=0, South345) / HBDF = IF(B 0, 1 B b, hb, South345 hb, South345=0, hb, South345) The above variables are defined as follows: Variable Unit Description RTSPP $/MWh Real-Time Settlement Point Price at the South345 Real-Time Settlement Point PriceThe Hub, for the 15-minute Settlement Interval. RTHBP $/MWh Real-Time hb, Real-Time Hub Bus Price at Hub Bus per SCED intervalThe energy price at Hub Bus for the SCED interval South345, y hb y.
