2.1Background

The Day Ahead Market Inter-SC Energy Trade of Energy Charge Codesettles for Energy trades between SCs. An Inter-SC Trade of Energy is an Energy quantity (MWh) traded from one SC to another SC for a specific Trading Hour, Location, and CAISO Market or process i.e., Day-Ahead Market (DAM) or Hour-Ahead Scheduling Process (HASP). The Location of an Inter-SC Trade of Energy can be a PNode, a Default Load Aggregation Point (LAP), or anExisting Zone (EZ) Generation Hub. Physical Trades that are validated pursuant to the provisions set forth in Section 28.1.6 of the CAISO Tariff and Section 9 of the BPM on Market Instruments are settled at the LMP at the PNode. Converted Physical Trades, which are Physical Trades or portions of Physical Trades that are not validated Post-Market are settled at the relevant Existing Zone (EZ) Generation Hub Price. All other Inter-SC Trades of Energy are settled at the relevant Default LAP or Existing Zone (EZ) Generation Hub Price.

An SC can have many ISTs of any type with another SC at the same location or at different locations. A unique Depend On Trade Name distinguishes multiple Physical ISTs of the same type, Location, hour, and market between the same pair of SCs.

2.2Description

Inter-SC Trades of Energy submitted in the Day Ahead Market are settled hourly based on the hourly LMPs at the applicable PNode, EZ Generation Hub, or Default LAPin those hours.

An Inter-SC Trade (IST) involves two SCs: the “From” SC and the “To” SC. The “From” SC is charged the same amount that the “To” SC is paid. Specifically, the “From” SC is charged the product of the valid quantity of the “From” Inter-SC Trade and the LMP at the appropriate PNode, EZ Generation Hub, or Default LAP. The “To” SC is paid the product of the valid quantity of the “To” Inter-SC Trade and the LMP at the appropriate PNode, EZ Generation Hub, or Default LAP. Inter-SC trades of Energy are settled on an hourly basis and the respective Settlements account is net to zero.
