Generating Units and Loads are modeled as individual physical resources in the FNM, and their Energy Supply and Demand is then mapped to their associated physical resources in the FNM using the relevant Generation and Load Distribution Factors, respectively. To the extent sufficient data is available or adequate estimates can be made for the Integrated Balancing Authority Areas, the CAISO may use this data for power flow calculations and Congestion Management in the CAISO Markets Processes. CAISO monitors but does not enforce the network constraints for Integrated Balancing Authority Areas in running the CAISO Markets Processes. CAISO models the resistive component for Transmission Losses on Integrated Balancing Authority Areas but does not allow such losses to determine LMPs. The use of the FNM in the DAM and the RTM incorporates Transmission Losses and allows modeling and enforcing all network constraints. This results in LMPs for Energy that reflects the System Marginal Energy Cost (SMEC), Marginal Cost of Losses (MCL), and Marginal Cost of Congestion (MCC). Although the SMEC component of the LMP is the same for all PNodes, based on the selection of a certain Reference Bus, the MCL and the MCC may vary across the network due to network characteristics and power flow patterns.
