All the substations are switching stations with no load or generation.  The changes in the Load Zone assignments do not impact calculation of Settlement Point Prices for the associated Load Zones since Locational Marginal Prices (LMPs) at Electrical Buses with no load have a zero weighting factor in the load-weighted average LMP calculations used to determine Load Zone Settlement Point Prices.
