PurposeThe California ISO market Scheduling paths are associated with the market Scheduling and tie points. In most cases, the nameregistered in the NAESB Electric Industry Registry (EIR) provided by the OATI webRegistry system is the same as the Tie Point. WECCtagging specifications require a single point to be designated as Point of Receipt/Point of Delivery (POR/POD) on NERC tags. Thefollowing table provides a cross reference to match the NERC POR/POD with the ISO market Scheduling path. This informationregarding registered POR/POD’s can also be found in the OATI Web Registry at cript /NAESBWRY/sys-main.wml, but it requires a security certificate.1.2.
