Existing Language
When the IFM cannot identify an electrically connected PNODE within the fixed level of proximity, a post process will be performed to determine the next closest electrically connected PNode and replace the LMP of the disconnected PNode with this price.  This price update will be done within the DAM price correction timeline.
Proposed Language
During a significant outage event in which many PNodes at certain locations are disconnected, for example, a Public Safety Power Shutoff (PSPS) event in the IFM, it may not be possible to identify an electrically connected PNode within the fixed level of proximity.  In such cases, the ISO market software uses the System Marginal Energy Cost (SMEC) as the LMP at such disconnected pricing node.
Reason For Revision
Due to the DAM software parameter update which increases the node replacement layer for disconnected node which eliminate the manual workaround in CRR and price correction
