Section 3 Market Performance Metrics
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 rose compared to the previous month, aligning with the increase in load discussed in the last section. Besides, the gas price also increased from June to July.
TABLE 3.1 below lists the binding constraints that resulted in relatively high or low DLAP prices on certain dates.

Figure 3.3 below shows the daily frequency of positive price spikes and negative prices by price range for the DLAPs in the FMM.
The cumulative frequency of prices in FMM above $250/MWh remained at 0 from June to July, while the cumulative frequency of negative prices decreased from 6.59 percent in June to 1.85 percent in July, correlated with an decrease in renewable generation curtailment.
