Day-Ahead Prices
Figure 3.1 shows the daily simple average prices for all hours in IFM for each of the four default load-aggregation points (DLAP): PG&E, SCE, SDG&E, and VEA.
Average Day-Ahead DLAP prices in PGAE, SCE, SDGE, and VEA all increased between from October to November, aligning with an increase of gas price.
TABLE 3.1 below lists the binding constraints that resulted in relatively high or low DLAP prices on certain dates.
