Performance payments for directly enrolled customers are calculated at the service agreement level by multiplying the event incremental load reduction (ILR) by $2/kWh. The interval ILR is the load reduction achieved during an ELRP event interval incremental to the non-event applicable baseline and any other existing commitment. The event ILR is the sum of the positive and negative interval ILR values across all intervals of a given event.
The ELRP baseline for directly enrolled customers is calculated with the following method:
Calculate the Energy Baseline (EB) – The EB is calculated on an hourly basis using the average of the preceding similar days, excluding those days when the customer: (1) was subject to an ELRP event, or (2) an event for a dually-enrolled demand response program, if applicable, or (3) was subject to a Public Safety Power Shutoff. For weekday events, the 10 non-excluded weekdays will be selected; for weekend and holiday events, the 4 non-excluded weekend and holiday days will be selected. If the customer elects to count exports in their ILR, the baseline calculation is modified to include net of exports (net of forward and reverse meter channels). Peak Day Pricing event days will not be excluded from the similar days in order to capture incrementality for ILR.
Calculate the Day-Of Adjustment Value (DOAV) – The DOAV is a ratio of (a) the average load of the first three hours of the four hours prior to the event to (b) the average load of the same hours from the days selected in accordance with Step 1 above. A DOAV shall not be less than 0.6 or greater than 1.40. If either (a) or (b) are negative, the DOAV is 1.0.
Calculate the Adjusted Energy Baseline (AEB) – When the EB is greater than zero, the AEB is calculated by multiplying the EB by the DOAV. There is no AEB when the EB is less than zero.
The ILR for Base Interruptible Program participants is calculated by subtracting the load during the overlapping event window from the pre-committed Firm Service Level. Base Interruptible Program participants are only eligible for ELRP compensation for ELRP events that overlap with Base Interruptible Program events, and only the incremental reduction below the Base Interruptible Program pre-committed Firm Service Level during the overlapping event window is compensated under the ELRP.
