Bill Determinants ERCOT Nodal Implementation Surcharge QNSAMT_<QSE> = NODSF * ∑zone (GSITETOTCM_<QSE>_<ZONE>) Where: QNSAMT: QSE NIS amount per 15-min interval ($) GSITETOTCM: Real-Time net metered generation in MWh per 15-min interval for the given QSE NODSF: $0.0663/MWh for every 15-min interval

  4. System Changes • Implemented in legacy zonal settlement architecture: QNSPRICE_<QSE> = NODSF for every 15-min interval QNSQTY_<QSE> = ∑zone (GSITETOTCM_<QSE>_<ZONE>) QNSAMT, QNSBILLAMT, QNSBILLQTY • Effective on trade date 10/1/2006 Initial Settlement • Rounding issue on NODSF QNSPRICE = 0.0663 → Extracts QNSPRICE = 0.07 → Statements
